This study aim to attempt mapping out the Land Use or Land Cover (LULC) status of Regional Project Coordination Committee (RPCC) between 2009-2019 with a view of detecting the land consumption rate and the changes that has taken place using RS and GIS techniques; serving as a precursor to the further study on urban induced variations or change in weather pattern of the cityn Rangpur City Corporation(RCC) is the main administrative functional area for both of Rangpur City and Rangpur division and experiencing a rapid changes in the field of urban sprawl, cultural and physical landscape,city growth. These agents of Land use or Land cover (LULC) varieties are responsible for multi-dimensional problems such as traffic congestion, waterlogging, and solid waste disposal, loss of agricultural land. In this regard, this study fulfills LULC changes by using Geographical Information Systems (GIS) and Remote Sensing (RS) as well as field survey was conducted for the measurement of change detection. The sources of data were Landsat 7 ETM and landsat 8 OLI/TIRS of both C1 level 1. Then after correcting the data, geometrically and radiometrically change detection and combined classification (supervised & unsupervised) were used. The study finds LULC changes built-up area, water source, agricultural land, bare soil in a change of percentage is 17.23, 2.58, -9.94, -10.19 respectively between 2009 and 2019. Among these changes, bare soil is changed to a great extent, which indicates the expansion of urban areas is utilizing the land to a proper extent.

GEOPROCESSAMENTO E SENSORIAMENTO REMOTO APLICADO NA DETERMINAÇÃO DA APTIDÃO AGRÍCOLA DE UMA MICROBACIA Cláudia Webber Corseuil1; Sérgio Campos1; Fernanda Leite Ribeiro2; Teresa Cristina Tarlé Pissarra3; Flavia Mazzer Rodrigues3 1Departamento de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP, seca@fca.unesp.br 2Departamento de Geociências, Universidade Estadual de Londrina, Londrina, PR3Departamento de Engenharia Rural, Faculdade de Ciências Agrárias e Veterinária, Universidade Estadual Paulista, Jaboticabal, SP 1 RESUMO Atividades como agricultura e pecuária causam impactos significativos no meio ambiente, principalmente quando estas são praticadas de forma intensiva, desconsiderando a fragilidade e o potencial de uso dos recursos naturais. A análise de vários critérios ambientais como, aptidão agrícola do solo, área com necessidade de proteção, zoneamento ambiental, entre outros, permite realizar uma caracterização do meio físico, biótico e sócio-econôminco, voltada para a utilização racional dos recursos naturais. Desta forma, é essencial que se faça o planejamento das atividades a serem desenvolvidas numa área, considerando a aptidão dos recursos nela disponíveis. Para uma utilização racional desses recursos, é necessário considerar o seu potencial de uso. No caso específico dos solos, a interpretação dos levantamentos de solos é de grande importância, pois as características de cada unidade é que determina o seu potencial de uso. Assim, este estudo objetivou analisar as classes de aptidão agrícola das terras de uma bacia hidrográfica por meio de sistema de informação geográfica (SIG). A microbacia do Arroio Ajuricaba localiza-se no Município de Marechal Cândido Rondon-PR, entre as coordenadas UTM 787309m E e 793892m E; 7275026m N e 7281310m N, do Fuso 21, apresentando uma área de 1681ha. A base cartográfica digital utilizada foi o mapa de solos, em escala de semidetalhe. Os resultados permitiram concluir que 42,41% da bacia apresentam uma boa aptidão para lavouras no nível de manejo de alta tecnologia (nível de manejo C), regular para o B e restrita para o A [classe 1(a)bC] e que 12% da área compreendem terras com aptidão regular para lavoura nos três níveis de manejo (classe 1abc). As terras da microbacia (14,24%) apresentam uma aptidão regular para o uso com lavouras no nível de manejo C, restrita para o B e inapta para o A [classe de aptidão 2(b)c]; 15,85% apresentam aptidão boa para pastagem plantada (classe 4P) e 12,21% são consideradas sem aptidão para uso agrícola (classe 6). Podemos dizer que 71,94% das terras possuem aptidão para lavouras, embora apresentem diferentes graus de limitações, que requerem tratamentos distintos para a sua conservação. UNITERMOS: unidades de solo, aptidão agrícola, geoprocessamento. CORSEUIL, C. W.; CAMPOS, S.; RIBEIRO, F. L.; PISSARRA, T. C. T.; RODRIGUES, F. M.. GEOPROCESSING AND REMOTE SENSING APPLIED TO DETERMINATION OF A WATERSHED AGRICULTURAL APTITUDE 2 ABSTRACT Soil use for the development of activities as agriculture and livestock has been causing great alterations in the environment, mainly when these are practiced intensively, disrespecting the fragility and aptitude of the natural resources. Therefore, it is essential that the planning of the agricultural activities is done, taking into consideration the several environmental criteria involved in the decision-making process. Thus, this study aimed to analyze the agricultural aptitude classes of lands from a watershed through geographical information system (GIS). The Arroio Ajuricaba watershed is located in theMunicipalityofMarechal Cândido Rondon- PR among the coordinates UTM 787309m E and 793892m E; 7275026m N and 7281310m N, in the Spindle 21, presenting an area of 1681ha. Soil maps, in semi detail scale, was the digital cartographic base used. The results allowed to conclude that 42.41% of the basin presented a good aptitude for farming in handling level of high technology (handling level C), regular aptitude for B, and restricted aptitude for A [class 1(a)bC] and that 12% of the area had regular aptitude for farming in the three handling levels (class 1abc). The watershed lands (14.24%) presented regular aptitude for farming in handling level C, restricted aptitude for B, and inapt for A [class of aptitude 2(b)c]; 15.85% presented good aptitude for planted pasture (class 4P) and 12.21% were considered without aptitude for agricultural use (class 6). We can say that 71.94% of the lands has aptitude for farming, although they present different degrees of limitations that request different treatments for its conservation. KEY WORDS: soil units, agricultural aptitude, geoprocessing

Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics. An integrated combination of mitigation, adaptation and resilience measures is currently considered as the most indicated way to resist SLR today and in the near future.References Aerts J.C.J.H., Hassan A., Savenije H.H.G., Khan M.F., 2000.

DETERMINAÇÃO DA CAPACIDADE DE USO DAS TERRAS DO MUNICÍPIO DE SÃO MANUEL - SP Osmar Delmanto JuniorSérgio CamposLincoln Gehring CardosoZacarias Xavier de BarrosDepartamento de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP. CP 237, CEP 18603-970. E-mail: seca@fca.unesp.br 1 RESUMO Esse trabalho objetivou a elaboração da carta de capacidade de uso das terras do Município de São Manuel - SP, visando o planejamento adequado da ocupação do solo, utilizado-se de Sistema de Informação Geográfica (SIG). A bacia situa-se entre as coordenadas geográficas 22º 28’ 20” e 22º 53’ 10” de latitudes S e os meridianos 48º 21’ 52” e 48º 48’ 00” de longitudes W Gr., apresentando uma área de 60.988ha. O mapa de capacidade de uso da terra do município foi elaborado a partir dos mapas de classes de declive e de solo, tomando-se por base as características de cada um e utilizando-se da tabela de julgamento de classes de capacidade de uso. As áreas da classe e subclasses de capacidade de uso das terras determinadas pelo SIG –IDRISI foram: IIe,s (22,64%); IIIe (8,62%); IIIe,s (15,83%); IIIs (29,97%); IVe (10,82%); VIe (3,95%) e VIIe (0,96%). Os resultados permitiram inferir que as subclasses mais significativas foram a IIIs e IIe,s. As classes de declive de 0 a 20% ocorrem em mais de ¾ do Município, sendo as áreas planas, as mais representativas, pois ocorrem em quase 1/3 da área total. O SIG mostrou-se uma excelente ferramenta para determinação da capacidade de uso da terra, demonstrando que a utilização do geoprocessamento facilita e agiliza o cruzamento dos dados digitais, permitindo seu armazenamento, que poderão ser utilizados para outras análises em futuros planejamentos geoambientais. UNITERMOS: Sistema de Informações Geográficas, unidades de solo, classes de declive, capacidade de uso da terra DELMANTO JUNIOR, O.; CAMPOS S.; CARDOSO, L.G.; BARROS, Z.X. LAND USE CAPABILITY DETERMINATION OF SÃO MANUEL MUNICIPALITY-SP 2 ABSTRACT The present work purposed a land use capability chart development from São Manuel Municipality-SP using a Geographical Information System - Idrisi aiming to contribute for a better territorial organization and soil occupation planning. The basin is located in the 22º 28’ 20” geographical co-ordinates at 22º 53’ 10” S latitude, 48º 21’ 52” and 48º 48’ 00” meridian of W Gr. longitude, presenting an area of 9180,12ha. The chart of the basin land use capability was elaborated from the soil and sloping class charts based on each one characteristics and using the class table of use capability. The class and subclass areas determined through the Geographical Information System IDRISI presented the following values: IIe,s (22,64%), IIIe (8,62%), IIIe,s (15,83%), IIIs (29,97%), IVe (10,82%), VIe (3,95%) and VIIe (0,96%). The results allowed to infer that the most significant sub classes were IIIs and IIe,s. The 0 to 20% sloping classes have occurred in more than ¾ of the district. Plane areas were the most significant since they occur in nearly 1/3 of the whole area. The Geographical Information System IDRISI has been an excellent tool to determine land use capability, specially related with geo-processing use. The later also facilitates the input, analysis and display of spatial environmental information as well as data digital storage which could be used for other analyses in further geo-environmental design. KEYWORDS: Geoprocessing, land-use capability, Geographical Information Systems.

Entikong is a sub-districts located in the borderline, northern end of Sanggau Regency directly adjacent to Sarawak, Malaysia. The growth of Entikong as a center of growth does not provide a downward trickle effect, but it creates an excessive resources exploitation effect to the surrounding area (backwash effect). The land use within an area should be adjusted to its function. For that reason, this research will determine the priority and rank of land use by using the Analytic Hierarchy Process (AHP). The ranking is based on four aspects of criteria; social, economic, institutional, and environmental. The hierarchy model is sorted into alternatives, criteria, and sub-criteria. The criteria and subcriteria are compared, as well as the value of consistency. After data processing and analyzing with Expert Choice software version 11, the researcher found that the main priority of land use in Entikong is for plantation, which is 29,7%.

A CULTURA DA CANA-DE-AÇÚCAR COMO FATOR DE RISCO PARA OS CÓRREGOS E AS NASCENTES BRUNA SOARES XAVIER DE BARROS1 E ZACARIAS XAVIER DE BARROS2 Departamento de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP, zacariasxb@fca.unesp.br1Pós-Doutoranda do Programa de Pós-Graduação - Energia na Agricultura, FCA/UNESP - Botucatu, SP. 2Professor Titular do Departamento de Engenharia Rural, FCA/UNESP - Botucatu, SP. 1 RESUMO O levantamento do uso e ocupação do solo tornou-se muito importante para se conhecer e determinar as principais culturas de uma região, pois a ação antrópica pode modificar profundamente as feições de uma paisagem nativa. Neste contexto, este trabalho visou analisar a ocupação do solo na bacia Fazenda Serra Negra, Botucatu-SP, no período de 1962 a 2014, no intuito de verificar a influência das diferentes culturas sobre as redes de drenagem e as nascentes na bacia. A bacia está situada entre as coordenadas de 22º 46’ 42” a 22º 48’ 12” de latitude S e 48º 24’ 04” a 48º 25’ 54” longitude Wgr, perfazendo uma área de 963,97 ha. O estudo possibilitou constatar que os córregos existentes em 1962 cederam espaços para o plantio da cana-de-açúcar restando apenas vestígios da rede de drenagem; pode-se também constatar que a várzea sofreu diminuição devido à construção de uma rede de drenos. Palavras-chave: Imagens aéreas; bacia hidrográfica; ocupação do solo. BARROS, B. S. X.; BARROS, Z. X.SUGAR CANE GROWING AS A RISK FACTOR FOR STREAMS AND SPRINGS 2 ABSTRACT The survey of land use and occupation has become very important to know and determine the main crops of the region, because human activities can profoundly change the features of a native landscape. In this context, this study aimed to analyze land use in the Fazenda Serra Negra drainage basin, Botucatu, São Paulo, from 1962 to 2014, in order to investigate the influence of different cultures on the drainage systems and springs in the basin. This basin is located between coordinates 22º46’42” to 22°48’'12”S latitude and 48°24’04” to 48°25’54”W longitude, covering an area of 963.97 ha. Through this study, it was possible to see that the existing streams in 1962 gave room to sugarcane growing, leaving only traces of the drainage system; it can also be seen that the plain suffered a decrease due to the building of a drain network. Keywords: aerial images; hydrographic basin; land use.

Rapid urbanization rates impact significantly on the nature of Land Cover patterns of the environment, which has been evident in the depletion of vegetal reserves and in general modifying the human climatic systems (Henderson, et al., 2017; Kumar, Masago, Mishra, & Fukushi, 2018; Luo and Lau, 2017). This study explores remote sensing classification technique and other auxiliary data to determine LULCC for a period of 50 years (1967-2016). The LULCC types identified were quantitatively evaluated using the change detection approach from results of maximum likelihood classification algorithm in GIS. Accuracy assessment results were evaluated and found to be between 56 to 98 percent of the LULC classification. The change detection analysis revealed change in the LULC types in Minna from 1976 to 2016. Built-up area increases from 74.82ha in 1976 to 116.58ha in 2016. Farmlands increased from 2.23 ha to 46.45ha and bared surface increases from 120.00ha to 161.31ha between 1976 to 2016 resulting to decline in vegetation, water body, and wetlands. The Decade of rapid urbanization was found to coincide with the period of increased Public Private Partnership Agreement (PPPA). Increase in farmlands was due to the adoption of urban agriculture which has influence on food security and the environmental sustainability. The observed increase in built up areas, farmlands and bare surfaces has substantially led to reduction in vegetation and water bodies. The oscillatory nature of water bodies LULCC which was not particularly consistent with the rates of urbanization also suggests that beyond the urbanization process, other factors may influence the LULCC of water bodies in urban settlements.

Abstract. Surface water and energy fluxes are essential components of the Earth system. Surface latent heat fluxes provide major energy input to the atmosphere. Despite the importance of these fluxes, state-of-the-art data sets of surface energy and water fluxes largely differ. The present paper introduces a new framework for the estimation of surface energy and water fluxes at the land surface, which allows for temporally and spatially high-resolved flux estimates at the quasi-global scale (50° S, 50° N) (High resOlution Land Atmosphere Parameters from Space – HOLAPS v1.0). The framework makes use of existing long-term satellite and reanalysis data records and ensures internally consistent estimates of the surface radiation and water fluxes. The manuscript introduces the technical details of the developed framework and provides results of a comprehensive sensitivity and evaluation study. Overall the root mean square difference (RMSD) was found to be 51.2 (30.7) W m−2 for hourly (daily) latent heat flux, and 84 (38) W m−2 for sensible heat flux when compared against 48 FLUXNET stations worldwide. The largest uncertainties of latent heat flux and net radiation were found to result from uncertainties in the solar radiation flux obtained from satellite data products.

CAPACIDADE DE USO DAS TERRAS DA BACIA DO RIBEIRÃO ÁGUA FRIA – BOFETE (SP) Sérgio CamposThiago Godinho dos SantosCristiane Lopes da SilvaZacarias Xavier de BarrosLincoln Gehring CardosoDepartamento de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, CP 237, CEP 18603-970, Botucatu - SP, E-mail: seca@fca.unesp.br. 1 RESUMO A determinação da capacidade de uso das terras numa bacia é muito importante para o planejamento e uso do solo, pois o uso inadequado e sem planejamento dessas terras provocam a baixa produtividade das culturas. Este trabalho visou definir as classes homogêneas de capacidade de uso da terra da bacia do Ribeirão Água Fria - Bofete (SP) para atender ao planejamento de práticas de conservação do solo desta área. A bacia situa-se entre as coordenadas geográficas 22o 58' 30`` a 23o 04' 30`` de latitude S e 48o 09' 30`` a 48o 18' 30`` de longitude W Gr., apresentando uma área de 9.180,12 hectares. A carta de capacidade de uso da terra da bacia foi elaborada a partir da carta clinográfica obtida por Santos et al. (1999), mapa pedológico do Estado de São Paulo (Oliveira et al., 1999), da tabela de julgamento de classes de capacidade de uso do solo (França, 1963) e das recomendações constantes no manual para levantamento utilitário do meio físico e classificação das terras no sistema de capacidade de uso (Lepsch et al., 1983). A discriminação, o mapeamento e a quantificação das áreas das classes e subclasses de capacidade de uso pelo Sistema de Informação Geográfica - IDRISI apresentaram os seguintes valores: IIIe,s - 517,020 ha (5,63%); IIIs - 863,150 ha (9,40%); IVe - 846,730 ha (9,23%); VIe - 871,110 ha (9,49%) e VIIe - 6082,115 ha (66,25%). Os resultados permitiram concluir que a bacia essencialmente constituída por 2/3 pela subclasse VIIe, ou seja, são terras que podem ser utilizadas por pastagens com uso moderado ou florestas, pois apresentam problemas complexos de erosão por causa de sua declividade. O Sistema de Informação Geográfica IDRISI permitiu através de seus módulos discriminar, mapear e quantificar as áreas das classes e subclasses de capacidade de uso das terras da bacia com rapidez e confiabilidade. UNITERMOS: Capacidade de uso, unidades de solo, classes de declive, bacia hidrográfica. CAMPOS, S., SANTOS, T.G., SILVA, C.L., BARROS, Z.X., CARDOSO, L.G. LAND USE CAPACITY OF AGUA FRIA STREAM BASIN – BOFETE (SP) 2 ABSTRACT The land use capacity determination is considered to be very important on land use planning, since its inadequate utilization can lead to low crop productivity. This work aimed to define the homogeneous classes of land use capacity of Agua Fria stream Basin – Bofete (SP) in order to help the soil conservation procedure planning in this area. The Basin is located from 22°58’30’’ to 23° 04’30’’ southern latitude and 48° 09’30’’ to 48°18’30’’ western longitude, in a 9180.12 ha area. The chart of land use capacity was established based on the clinographic chart by Santos et al. (1999), São Paulo state pedological map (Oliveira et al, 1999), class determination chart of soil use capacity (França, 1963) and the recommendations from the manual for physical environmental utilitary survey in the using capacity system (Lepsch et al, 1983). The determination, mapping and quantification of class and subclass areas of using capacity by the Geographic Information System – IDRISI presented the following values: IIIe,s – 517.020 ha (5.63%); IIIs 863.150 ha (9.40 %); IVe – 846.730 ha (9.23%); VIe – 871.110 ha (9.49 %) e VIIe – 6082.115 ha (66.25 %). The results allowed to conclude that the Basin is 2/3 essentially constituted by VIIe subclass, i.e., land that could be used for moderate grazing or forests, since it has complex erosion problems due to its slope. The Geographic Information System IDRISI by its modules enabled to discriminate, map and quantify the land use capacity class and subclass areas of the basin fast and reliably.

Daily, quasi-global (50° N–S and 180° W–E), satellite-based estimates of actual evapotranspiration at 0.25° spatial resolution have recently become available, generated by the Global Land Evaporation Amsterdam Model (GLEAM). We investigate the use of these data to improve the performance of a simple lumped catchment-scale hydrologic model driven by satellite-based precipitation estimates to generate streamflow simulations for a poorly gauged basin in Africa. In one approach, we use GLEAM to constrain the evapotranspiration estimates generated by the model, thereby modifying daily water balance and improving model performance. In an alternative approach, we instead change the structure of the model to improve its ability to simulate actual evapotranspiration (as estimated by GLEAM). Finally, we test whether the GLEAM product is able to further improve the performance of the structurally modified model. Results indicate that while both approaches can provide improved simulations of streamflow, the second approach also improves the simulation of actual evapotranspiration significantly, which substantiates the importance of making diagnostic structural improvements to hydrologic models whenever possible.

The high prevalence of gender-based violence (GBV) in armed conflict has been documented in various national contexts, but less is known about the complex pathways that constitute the relation between the two. Employing a community-based collaborative approach, we constructed a community-informed socioecological conceptual model from a feminist perspective, detailing how armed conflict relates to GBV in a conflict-affected rural community in Northeastern Uganda. The research questions were as follows: (1) How does the community conceptualize GBV? and (2) How does armed conflict relate to GBV? Nine focus group discussions divided by gender, age, and profession and six key informant interviews were conducted. Participants’ ages ranged from 9 to 80 years ( n = 34 girls/women, n = 43 boys/men). Grounded theory was used in analysis. Participants conceptualized eight forms of and 22 interactive variables that contributed to GBV. Armed conflict affected physical violence/quarreling, sexual violence, early marriage, and land grabbing via a direct pathway and four indirect pathways initiated through looting of resources, militarization of the community, death of a parent(s) or husband, and sexual violence. The findings suggest that community, organizational, and policy-level interventions, which include attention to intersecting vulnerabilities for exposure to GBV in conflict-affected settings, should be prioritized. While tertiary psychological interventions with women and girls affected by GBV in these areas should not be eliminated, we suggest that policy makers and members of community and organizational efforts make systemic and structural changes.

The collection, sale, and processing of non-wood forest products are becoming a significant factor in stimulating regional development and improving the economic situation, especially of poor rural communities. The fashion for a healthy lifestyle is also conducive to the growth of interest in such goods. Among them, birch sap is indicated as one of the most promising non-wood forest resources of central Europe, with very wide possibilities of its practical use, e.g., in the food, pharmaceutical, and cosmetics industries. The potential increase in birch sap commercial use prompts research on both the principles of its collection and the impact of various factors on its quality. In this presentation, we decided to investigate how the daily volume and selected sap parameters change depending on the location of the holes in relation to the cardinal directions. The research was conducted in April 2018, in the eastern part of Poland, in a stand with a dominant share of silver birch (Betula pendula Roth) at the age of approximately 100 years, in a fresh broadleaved forest habitat. On each of the six selected trees, four holes were drilled at a height of 1 m, positioned according to the cardinal directions (N-E-S-W). Sap was collected twice, one week apart, always after 24 h of leak. In each case, the daily volume of the obtained sap was determined, and then the selected properties of the sap were tested: electrolytic conductivity (proving, among others, the content of pro-health minerals), refractometric index (proving the approximate content of sugar), pH, and the percent of dry matter. As a result of the research, it was found that the location of boreholes in the tree trunk in relation to the cardinal directions (N-E-S-W) does not affect the efficiency of the birch sap leak intensity or other tested physical sap properties: refraction, pH value, and percentage of dry matter. However, a slight effect on the electrolytic conductivity was found. Therefore, it can be summarized that the cardinal directions do not affect the usefulness of the sap for the production of birch syrup, but may affect a nutritional value.

Solar radiation is a key element of the Earth’s climate system and one of the most important variables in the energy balance of the active surface. The inflow of radiant energy to the Earth’s surface depends on the movement (circulation) of the atmosphere and on the associated changes in the amount of aerosols contained in the atmosphere as well as on cloudiness changes (which reduce the inflow of radiation to the Earth’s surface through reflection, dispersion and absorption processes). In that context, the work detailed in this paper had as its main aim a determination of the influence of atmospheric circulation on the amount of global solar radiation reaching the land surface in Poland. The research was based on source material from 1986–2015, originating from meteorological reanalyses and satellite products. Global solar radiation was analysed based on data from CM SAF satellite products, while atmospheric circulation types were designated with the use of modified version of the Lityński’s classification. Mean daily sums of radiation during individual circulation types, during A, 0, C macrotypes and on days with advection from particular directions were presented. Also the spatial distribution of radiation over the area of Poland during individual circulation types was shown. In the analyses special attention was paid to days with extremely large sums of solar radiation (above the 0.95 percentile). The largest daily sums of solar radiation are connected with anticyclonic circulation types, and the smallest ones – with cyclonic types. The largest mean daily sum of solar radiation occurs during south-western anticyclonic circulation, which is related to the significantly expanded Azores High. The smallest daily sums of solar radiation occur during cyclonic types, with advection of air masses from the north and east – in spring during NWC type, in autumn during EC type, in summer and winter during NEC type. The spatial distribution of solar radiation daily sums over the territory of Poland also depends on the circulation type. For most of the year, the circulation types with the northern and eastern components (N-NE-E) are associated with the reduction of the amount of solar radiation from north to south, while the inflow of air masses from the S-SW-W directions favours the reduction of radiation from south to north. Extremely large sums of solar radiation occur most probably during anticyclonic types with advection of air masses from SW, S and SE, and during the advectionless circulation 0A (conditional probability 0.13, 0.13, 0.11 and 0.10 respectively). The paper also demonstrates that the circulation type (i.e. prevailing pressure system) has a greater influence on daily sums of global solar radiation over Poland than the direction of air masses advection. The research results show that atmospheric circulation plays a significant role in determining the amount of solar radiation reaching the land surface in Poland.

Abstract The aim of this study was to identify clear air boundaries and to obtain spatial distribution of convective areas associated with the sea breeze over the Iberian Mediterranean zone and the isle of Mallorca, both in Spain. Daytime Advanced Very High Resolution Radiometer (AVHRR) data from National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites were collected for May–October 2004. A cloud detection algorithm was used to identify clouds to derive daytime sea-breeze cloud frequency composites over land. The high-resolution composites aided in identifying the location of five preferential sea-breeze convergence zones (SBCZ) in relation to the shape of coastline and orographic effects. Additionally, eight regimes were designated using mean boundary layer wind speed and direction to provide statistics about the effect of prevailing large-scale flows on sea-breeze convection over the five SBCZ. The offshore SW to W and the NW to N regimes were characterized by high cloud frequencies parallel to the coast. Small differences in mean cloud frequency values from morning to afternoon composites were detected with these regimes because sea-breeze fronts tended to form early and persist into the afternoon. Just the opposite occurred under the onshore NE to E and SE to S regimes. It was found that light to moderate (≤5.1 m s−1) winds aloft result in more clouds at the leading edge of sea breezes. In contrast, strong synoptic-scale (>5.1 m s−1) flows weaken boundary layer convergence. The results from this satellite meteorology study could have practical applications for many people including those that forecast the weather and those that use the forecast for making decisions related to energy use, fishing, recreation, or agriculture activities, as well as for estimating pollution or issuing warnings for heavy rain or flash flooding.

Entretanto, na dessalinização, produz-se, além de água potável, salmoura que, normalmente é descartada no solo ou no corpo hídrico, causando problemas ambientais. Na comunidade Serra Mossoró e o Assentamento rural Santa Elza, beneficiadas com estação de tratamento por osmose reversa, tem aproveitado o rejeito salino em viveiros de criação de tilápias. Porém, esta atividade não reduz a salinidade do rejeito salino e, produz efluente rico em matéria orgânica com alta salinidade. Deste modo, objetivou-se de investigar a produção, a qualidade e o potencial de fitoextração de sais da erva sal (Atriplex nummularia) cultivada em solos fertirrigados com rejeito salino após utilização em viveiro de piscicultura afim reduzir os impactos do descarte do rejeito nos solos. Os resultados mostram que a erva sal produz alto rendimento de fitomassa com bom percentual de proteína bruta quando cultivado em solos fertirrigados com efluente da piscicultura oriundo de rejeito salino de dessalinizadores. A elevada extração de sais pela cultura permite a retirada de íons tóxicos Cl- e Na+ no solo por ocasião da colheita. Palavras-chave: Recursos hídricos; Reuso; Dessalinização DIAS, N. S.; QUEIROZ, R.

FERTIRRIGATED WITH PISCICULTURE EFFLUENT FROM VIVEIROS FILLED WITH REJECT BRINE FROM DESALINATION 2 ABSTRACT In semiarid zone from Brazil due the high-salinity of well water, reverse osmosis has been used to insure drinking water for the rural population. However, in desalination process, it generates drinking water, but also rejects brine that is, normally disposed in soil or water bodies, causing environmental problems. In the Serra Mossoró community and the Santa Elza rural settlement, benefited with desalination plant by reverse osmosis, it has used the reject brine to fillet tilapia nurseries. However, this activity does not reduce the salinity of reject brine and also make effluent that, though organic matter rich, has high-salinity. A study was carried out aiming to evaluate the yield, quality and phytoextractor potential of saltbush plants (Atriplex nummularia) cultivated in soils fertirrigated with reject brine after use in fish farms to reduce impact of land disposal of reject brine from desalination plants on soil. The results show that the saltbush makes phytomass yield high with good percentage of crude protein when fertirrigated effluent from fish farms derived of reject brine from desalination plants. The high salt extraction by the crop allows the removal of toxic Cl- and Na+ ions in the soil at the time harvest. Keywords: Water resources; Reuse, Desalination.

Abstract Planted pastures (mainly Brachiaria spp) are the most extensive land use in the cerrado (savannas of central Brazil) with an area of approximately 50 × 106 ha. The objective of the study was to assess the effects of pasture restoration on the N dynamics (net N mineralization/nitrification, available inorganic N and soil N oxide gas fluxes—NO and N2O), C dynamics (CO2 fluxes and microbial biomass carbon), and diversity of the soil bacterial community using denaturing gradient gel electrophoresis (DGGE) profiles. Sampling was done monthly on a farm in Planaltina, Goiás, Brazil (15°13′S, 47°42′W) from November 2001 to April 2002. Three areas of cerradão (dense cerrado) were converted to pasture (Brachiaria brizantha) in 1991, and after 8 years degradation was evident with the decreasing plant biomass production. Methods to restore these pastures were investigated for their sustainability, principally their effects on trace gas emissions. The pastures have been managed since 1999 as follows: 1) fertilized plot (N = 60 kg ha−1 yr−1, P = 12 kg ha−1 yr−1); 2) grass–legume plot, Brachiaria associated with a legume (Stylosanthes guianensis) with addition of P (12 kg ha−1 yr−1); and 3) a traditional plot without management. A fourth area of cerradão was converted to pasture in 1999 and was not managed (young pasture). Ammonium was the predominant inorganic N form in the soils (∼76 mg N kg−1) for all treatments throughout the study. In December 2001 a reduction in average soil N-NH4+ was observed (∼30 mg N kg−1) compared to November 2001, probably related to plant demand. All plots had high variability of soil N gases emissions, but during the wet season, the NO and N2O soil fluxes were near zero. The results of the water addition experiment made during the dry season (September 2002) indicated that the transition of dry to wet season is an important period for the production of N gases in the fertilized pasture and in the young pasture. Soil CO2 fluxes also increased after the water addition and the grass–legume plot had the highest increase in soil respiration (from ∼2 to 8.3 μmol m−2 s−1). The lowest values of soil respiration and microbial biomass carbon (∼320 mg C kg−1 soil) tended to be observed in the young pasture, because the superficial layer of the soil (0–10 cm) was removed during the conversion to pasture. Trace gas emissions measured after the water addition experiment corresponded to rapid changes in the soil bacterial community. The young pasture sample showed the lowest level of similarity in relation to the others, indicating that the bacterial community is also influenced by the time since conversion. This study indicates that the restoration technique of including Stylosanthes guianensis with B. brizantha increases plant productivity without the peaks of N oxide gas emissions that are often associated with the use of N fertilizers. Additionally, the soil bacterial community structure may be restored to one similar to that of native cerrado grasslands, suggesting that this restoration method may beneficially affect bacterially mediated processes.

Background:Evidence has accumulated in recent years regarding the scope of local and global climate changes attributed to exacerbating anthropogenic factors such as accelerating population growth, urbanization, industrialization, traffic and energy use. Remote space monitoring, unlike ground-based measurements, has the advantage of providing global coverage on a daily basis.Methods:MODIS (Moderate Resolution Imaging Spectroradiometer) Aqua and Terra 1°×1° spatial resolution as well as the 1 km higher resolution of Aqua-MODIS were investigated for a global overview of megacities temperature variations, as well as the recent trends of the 10 largest Monsoon Asian megacities.Results:The average Land Surface Temperature (LST) cross-sections of the 10 Asian megacities were examined for June-August 2002-2014. Temperature variations fit a spatial bell-shaped curve, with a pronounced maximum over the city center. Nighttime data indicated sharp LST decreases with distance from the city center, particularly in the coldest cities, those of Tokyo, Seoul, Osaka and Beijing.Conclusion:Daytime latitudinal (E-W) and longitudinal (N-S) Surface Urban Heat Islands (SUHI) have steeper gradients than for nighttime data. During daytime, the SUHI gradients are largest in Tokyo, Seoul, Osaka and Beijing with values reaching 15oC followed by the cities of Shanghai and Guangzhou with ~11oC, and Karachi with ~5oC SUHI. Nighttime SUHIs were more moderate, 4-6oC in Tokyo, Seoul ~5oC, Osaka 5-7oC and Beijing ~7oC. Only in the three largest megacities,i.e., Tokyo, Guangzhou and Shanghai, did the nighttime LST trends decline.

ABSTRACT The form of occupation of the state of Rondônia, Brazil, favored the extensive agriculture, which resulted in a fast deforestation. The removal of forests and inadequate soil management and use, combined with a hot and wet climate, affected the soil chemical, physical, and biological attributes. In search for less impacting and alternatives that promote greater soil conservation for coffee production in the North region of Brazil, the objective of this work was to evaluate the effects of two coffee crop systems on the soil chemical and microbiological attributes. The treatments consisted of a shaded coffee crop (SCC) and a full-sun coffee crop (FCC). A completely randomized design was used, with four clusters per treatment and seven sampling points per cluster, which constituted a replication, totaling 28 replications per treatment. The data were collected in April 2018, in a rural property in the municipality of Cacoal, state of Rondônia, Brazil (11º21’50’’S, 61º20’10’’W, and altitude of 238 m). The soil organic matter, pH, P, K, Ca, Mg, Al, H+Al, base saturation, and basal respiration were determined. The soil under SCC had higher Ca content, pH, and base saturation, and lower potential acidity (H+Al) and Al content than that under FCC. The litterfall on the soil under FCC presented higher N and Mg contents. The soil basal respiration increased in the first 5 cm depth in the treatment with SCC.

The pandemic that occurred this year created conditions that changed the activities of parents and children, the role of parents working outside the home often led to a lack of parental involvement in child development, especially the development of independence. The conditions of the Covid-19 pandemic have caused parents and children to be in one place at the same time. This study aims to determine the effect of parental involvement and maternal employment status on the independence of children aged 7-8 years in the Covid-19 pandemic situation. This quantitative research uses a comparative causal ex-post facto design, with groups of working mothers and groups of non-working mothers. The sample of each group was 60 people who were randomly selected. The findings of the study with the calculation of the two-way ANOVA test obtained the value of Fo = 4.616> F table = 3.92 or with p-value = 0.034 <α = 0.05, indicating that there is an interaction between parental involvement and maternal employment status on children's independence, and Based on the results of hypothesis testing, there is no effect of parental involvement and mother's work status on the independence of the child even though there are differences in the average results of children's independence.

CP: 237 – CEP: 18603-970. E-mail: klar@fca.unesp.br 1 RESUMO O estudo da evaporação da água tem sido bastante empregado para estimar a evapotranspiração de culturas, constituído-se num fator de importância relevante para planejamento e manejo da irrigação. Nas ultimas décadas, o cultivo em ambiente protegido, principalmente de hortaliças, tem sido muito utilizado no Brasil. No entanto, estudos referentes ao manejo de água em ambientes protegidos têm sido ainda pouco pesquisados. Este trabalho teve como objetivo, estimar a evaporação (Eo) e evapotranspiração de referência (ETo), dentro e fora das estufas, utilizando-se o método do tanque classe “A”, e estabelecer correlações entre estas variáveis medidas em duas estufas com orientações geográficas distintas (N-S, L-O). O experimento foi conduzido na área experimental do Departamento de Engenharia Rural da Faculdade de Ciências Agronômicas da Universidade Estadual Paulista - UNESP, campus de Botucatu-SP, no período de setembro de 1997 a fevereiro de 1998. Observou-se que a evaporação e a evapotranspiração de referência obtidas fora das estufas correlacionaram-se de forma positiva com as estimadas dentro das mesmas; que houve pequena variação na evaporação e evapotranspiração de referência, estimadas no interior das estufas; e que é possível estimar-se a evaporação e evapotranspiração de referência, dentro da estufa orientada no sentido Norte/Sul, através de dados de Eo e ETo obtidos fora destas e no interior da Leste/Oeste.

PLASTIC TUNNEL ORIENTATION INFLUENCE ON EVAPORATION AND REFERENCE EVAPOTRANSPIRATION 2 ABSTRACT The water evaporation has been employed to predict plant evapotranspiration in order to design irrigation management. Plastic tunnels has been used for cultivation of many plants, mainly vegetables, but few water use researches have been made under plastic tunnel conditions in Brazil. For this reason, the main objective of this study was to estimate evaporation - Eo (class A pan metthod) and reference evapotranspiration – E To inside and outside greenhouses. Two plastic tunnels oriented North/South (N/S) and East/West (E/W) were used. The study was developed at the Agricultural Engineering Department, FCA/UNESP, Botucatu – SP from 09/1997 to 02/1998. The evaporation and the reference evapotranspiration obtained from classe A pan out the tunnels had positive correlations to those inside the tunnels, consequently it is possible to evaluate Eo and ETo inside tunnels from outside data. A positive correlation were founded between class A pan data obtained from both plastic tunnels. KEYWORDS: Evaporation, Reference Evapotranspiration, Plastic Tunnel

An improved fallow is a soil fertility agroforestry technique that has commonly been used in the staple maize production systems of Zambia and sub-Saharan Africa. Several studies have assessed the adoption and impact of the improved fallow on maize production. Generally, it has been observed that though the improved fallow does increase maize yields, its efficacy on welfare in terms of increased income is low. The use of the technique on cash crops that could significantly contribute to household welfare has rarely been investigated. This study assessed the factors affecting the adoption and impact of improved fallows on a commonly grown cash crop, cotton, in the cotton growing provinces of Zambia. The study used a sub sample (N=1206) of the nationally representative 2014/15 Rural Agricultural Livelihoods Survey (RALS) data which was randomly collected by the Indaba Agricultural Policy Research Institute (IAPRI) and Central Statistical Office (CSO) of Zambia. The determinants of improved fallow adoption among the cotton farmers were examined through the use of the probit model while the impact of the technique on cotton production and income was evaluated by using the propensity score matching and the endogenous switching regression models. Among the socioeconomic factors significantly increasing the probability of improved fallow adoption included: increases in age, education level, and per capita productive assets of the farmer, in addition to the area under cotton production and the distance of the homestead to the market. Institutional factors found to increase the farmer&rsquo;s likelihood of adopting the improved fallow in the cotton production systems included; farmer membership to a cooperative, receiving improved fallow seedlings from the government projects and having information on agroforestry tree species. On the other hand, an increase in land size per capita was found to negatively affect the likelihood of improved tree fallow adoption. Impact estimates showed significant cotton yield and income increases as a result of adopting the technique. The continuous provision of information on relatively new techniques such as the improved fallows preferably in farmer organized groups, and support towards the provision of the technique&rsquo;s planting materials are some of the areas requiring government and NGOs attention. In addition, the study recommends that the farmers&rsquo; formal education level should be enhanced and that improved tree fallows should also be explicitly promoted on cash crops that have similar agronomic requirements to maize such as cotton.

Foram gerados os seguintes mapas temáticos: Índice de Vegetação da Diferença Normalizada (NDVI), Índice de Área Foliar (IAF), albedo e temperatura de superfície (Ts), saldo de radiação instantâneo (Rn) e evapotranspiração real diária (ETr). O NDVI foi maior em janeiro de 2015 e o albedo e Ts foram maiores em 2016 (0,23 e 37,44 °C), ao passo que em 2015, os valores foram de 0,20 e 34,11 °C, relacionando-se às condições meteorológicas e uso do solo. O Rn variou de 520,06 a 540,22 W m-2 nos dois anos e, para a ETr, verificou-se a maior média em janeiro de 2015 (3,41 mm dia-1), devido ao maior NDVI e precipitações, evidenciando maior disponibilidade de água na vegetação e no solo. As técnicas de sensoriamento remoto possibilitaram o monitoramento do município de Arcoverde-PE, determinando os parâmetros biofísicos nos diferentes usos do solo, predizendo os processos futuros de degradação e consequente desertificação na localidade.

The following thematic maps were generated: Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI), albedo and surface temperature (Ts), Net radiation (Rn) and daily reference evapotranspiration (ETr). The NDVI was higher on January 2015 and the albedo and Ts were higher in 2016 (0.23 and 37.44 °C), whereas in 2015, the values were 0.20 and 34.11 °C, related to the meteorological conditions and the land use. The Rn ranged from 520.06 to 540.22 W m-² in two years of study and, for the ETr, the highest average was recorded on January 2015 (3.41 mm day-1), due to the higher NDVI and rainfall index, evidencing greater availability of water in the vegetation and soil. The remote sensing techniques allowed the monitoring of the municipality of Arcoverde, determining the biophysical parameters in the different uses of soil, anticipating the future degradation processes and consequent desertification in the place. Keywords: caatinga, vegetation, environmental monitoring, use of the soil, agrometeorology.

The effects of biochar and biochar combined with N-fertilizer on the content of soil organic matter in water-stable aggregates were investigated. A field experiment was conducted with different biochar application rates: B0 control (0 t ha-1), B10 (10 t ha-1) and B20 (20 t ha-1) and 0 (no N), 1st and 2nd levels of nitrogen fertilization on silt loam Haplic Luvisol (Dolna Malanta, Slovakia), in 2014. The N doses of level 1 were calculated on required average crop production using balance method. Level 2 included additional 100% of N in year 2014 and additional 50% of N in year 2016. The effects were investigated during the growing seasons of spring barley and spring wheat in 2014 and 2016, respectively. Results indicate that the B20N2 treatment significantly increased the proportion of water-stable macro-aggregates (WSAma) and reduced water-stable micro-aggregates (WSAmi). Aggregate stability increased only in the B20N1 treatment. The B20N2 treatment showed a robust decrease by 27% in the WSAma of 0.5-0.25 mm. On the other hand, an increase by 56% was observed in the content of WSAma with fractions 3-2 mm compared to the B0N0 treatment. The effect of N fertilizer on WSAma was confirmed only in the case of the B10N2 treatment. The proportion of WSAma with fractions 3-2 mm decreased by 42%, while the size fraction of 0.5-0.25 mm increased by 30% compared to the B10N0 treatment. The content of WSAma with fractions 1-0.5 mm decreased with time. On the contrary, the content of WSAma with particle sizes above 5 mm increased with time in all treatments except the B10N2 and B20N2 treatments. A statistically significant trend was identified in the proportion of WSA in the B10N2 and B20N2 treatments, which indicates that biochar with higher application levels of N fertilizer stabilizes the proportion of water-stable aggregates. In all treatments, the content of soil organic carbon (SOC) and labile carbon (CL) in WSAmi was lower than those in WSAma. A considerable decrease of SOC in the WSAma >5 mm and an increase of SOC in WSAmi were observed when biochar was applied at the rate of 10 t ha-1. Contents of SOC in WSAmi increased as a result of adding biochar combined with N fertilizer at first level. CL in WSA significantly increased in all size fractions of WSA.References Abiven S., Hund A., Martinsen V., Cornelissen G., 2015.

Dito isto, em Mossoró-RN (5º11’31’’S, 37º20’40’’O), entre setembro de 2014 e janeiro de 2015, desenvolveu-se esta pesquisa, com o objetivo de quantificar alterações nas características químicas de um Argissolo vermelho-amarelo Eutrófico cultivado com plantas de mamona (Ricinus communis L.) que receberam aplicação de percolado de aterro sanitário. O experimento foi conduzido em blocos casualizados com cinco tratamentos e quatro repetições; do total da demanda hídrica da cultura, aplicou-se inicialmente percentuais (0; 20; 40; 60 e 80%) de percolado de aterro sanitário e, em seguida, o restante em água de abastecimento. Concluiu-se que com o incremento do percentual de percolado aplicado houve aumento do pH e no quantitativo de Ni, Cd e Pb, assim como os teores de Ca e Cu foram reduzidos nos primeiros 0,20 m. A condutividade elétrica do extrato de saturação, e o quantitativo de Fe e Cu não variou ao longo do perfil, entretanto, verificou-se aumento na capacidade de troca catiônica (CTC) - até a dose de 60% de percolado, e do percentual de sódio trocável (PST) – embora sempre abaixo de 15%. A variação no quantitativo de Mn, Zn, Ni, Cd e Pb não ultrapassou os limites impostos pela legislação vigente.

Thus, in Mossoró, RN (5º11’31'”S, 37º20’40” W), between September 2014 and January 2015, this research was developed with the objective of quantifying changes in the chemical characteristics of a Eutrophic red-yellow agrisol cultivated with castor bean plants (Ricinus communis L.) that received landfill percolation. The experiment was conducted in a randomized block with five treatments and four replicates; percentages (0%, 20%, 40%, 60% and 80%) of percolated landfill were initially applied, followed by water supply. It was concluded that, with the increase of the percolation percentage applied, there was an increase in pH and in the quantity of Ni, Cd and Pb, while the Ca and Cu contents were reduced in the first 0.20 m. The electrical conductivity of the saturation extract, and the quantitative Fe and Cu did not vary along the profile. Nevertheless, there was an increase in CTC – up to 60% of the percolation, and exchangeable sodium percentage (ESP) – albeit always below 15%. The variation in the quantity of Mn, Zn, Ni, Cd and Pb did not exceed the limits imposed by the current legislation. Keywords: liquid waste, heavy metals, sustainability

Teacher's abilities to understand the benefits and use of media literacy play an important role in dealing with children as digital natives. Media literacy education can be an instrument through the use of blended-learning websites to address the challenges of education in the 21st century and learning solutions during and after the Covid-19 pandemic. This study aims to figure the teacher's perspective in understanding media literacy as an instrument for implementing blended-learning in early-childhood classes. Using a qualitative approach, this study combines two types of data. Data collection involved kindergarten teachers, six people as informants who attended the interviews and twenty-six participants who filled out questionnaires. Typological data analysis was used for qualitative data as well as simple statistical analysis to calculate the percentage of teacher perspectives on questionnaires collected the pandemic. The findings show five categories from the teacher's perspective. First, about the ability to carry out website-based blended-learning and the use of technology in classrooms and distance learning is still low. It must be transformed into more creative and innovative one. Encouraging teacher awareness of the importance of media literacy education for teachers as a more effective integrated learning approach, especially in rural or remote areas, to be the second finding. Third, national action is needed to change from traditional to blended-learning culture. Fourth, the high need for strong environmental support, such as related-party policies and competency training is the most important finding in this study. Finally, the need for an increase in the ease of access to technology use from all related parties, because the biggest impact of the Covid-19 pandemic is on ECE, which is closely related to the perspective of teachers on technology. The research implication demands increase in technology systems and connections between educators, parents, institutional managers, and education policy holders, for ECE services in urban areas for disadvantaged children, and all children in rural or remote areas.

Abstract. The online-coupled Weather Research and Forecasting model with Chemistry (WRF-Chem) is used to simulate the direct and semi-direct radiative impacts of smoke particles over the Southeast Asian Marine Continents (MC, 10° S–10° N, 90° E–150° E) during October 2006 when a significant El Nino event caused the highest biomass burning activity since 1997. With the use of OC (Organic Carbon)/BC (Black Carbon) ratio of 10 in the smoke emission inventory, the baseline simulation shows that the low-level clouds amplifying effect on smoke absorption led to a warming effect at the top-of-atmosphere (TOA) with a domain/monthly average forcing value of ~20 W m−2 over the islands of Borneo and Sumatra. The smoke-induced monthly average daytime heating (0.3 K) that is largely confined above the low-level clouds results in the local convergence over the smoke source region. This heating-induced convergence coupled with daytime planetary boundary layer turbulent mixing, transports more smoke particles above the planetary boundary layer height (PBLH), hence rendering a positive feedback. This positive feedback contrasts with the decrease of cloud fraction resulted from the combined effects of smoke heating within the cloud layer and the more stability in the boundary layer; the latter can be considered as a negative feedback in which decrease of cloud fraction weakens the heating by smoke particles above the clouds. During nighttime, the elevated smoke layer (above clouds in daytime) is decoupled from boundary layer, and the reduction of PBLH due to the residual surface cooling from the daytime lead to the accumulation of smoke particles near the surface. Because of smoke radiative extinction, on monthly basis, the amount of the solar input at the surface is reduced as large as 60 W m−2, which lead to the decrease of sensible heat, latent heat, 2 m air temperature, and PBLH by a maximum of 20 W m−2, 20 W m−2, 1 K, 120 m, respectively. The decrease of boundary layer mixing and the generation of convergence above the PBL also results in a reduction of precipitable water 1–2 km above the PBLH and more precipitable water near the surface and in upper part of the middle troposphere with changes around 0.1 mm. Overall, there is less of a change of column water vapor over the land, and an increase of water vapor amount over the Karimata Strait. The cloud changes over continents are mostly occurred over the islands of Sumatra and Borneo during the daytime, where the low-level cloud fraction decreases more than 10%. However, the change of local wind (include sea breeze) induced by the smoke radiative feedback leads to more convergence over Karimata Strait and south coastal area of Kalimantan during both daytime and night time; consequently, cloud fraction is increased there up to 20%. The sensitivities with different OC/BC ratio show the importance of the smoke single scattering albedo for the smoke semi-direct effects. A case study on 31 October 2006 further demonstrated a much larger (more than twice of the monthly average) feedback induced by smoke aerosols. The decreased sea breeze during big events can lead to prominent increase (40%) of low-level cloud over coastal water. Lastly, the direct and semi-direct radiative impact of smoke particles over the Southeast Asian Marine Continents is summarized as a conceptual model.

The introduction of basic computer media for early childhood is very important because it is one of the skills that children need in this century. Need to support parents and teachers in developing the implementation of the use of computer technology at home or at school. This study aims to determine and understand the state of learning conducted based on technology. This research uses a qualitative approach with a case study model. This study involved 15 children and 5 parents. Data obtained through interviews (children and parents) and questionnaires for parents. The results showed that children who were introduced to and taught basic computers earlier became more skilled in learning activities. Suggestions for further research to be more in-depth both qualitatively and quantitatively explore the use of the latest technology to prepare future generations who have 21st century skills.

Physical activity is very important for early childhood, especially outdoor activities that add a lot of new experiences. This study aims to check the relationship of children's outdoor activities and parenting styles and children's social skills. The participants are 125 parents of early childhood who attend kindergarten. The research method is a descriptive study using the relational screening model. The results showed that there was a relationship between outside play and parenting style on the social skills of children in their childhood. Democratic parenting styles are found to promote children's social skills, while authoritative parenting styles have a negative correlation with interpersonal skills, the ability to express verbally, self-control, listening skills, emotional management and adaptation to change. In the sub-dimensions of anger management and adaptation to changing skills is a significant difference between authoritative parenting styles and not permissive parenting with children's social skills.

The aim was to evaluate the effect of modalities of fall-irrigated maize (Zea mays L.) intercropped with tropical forages on the components of production, grain, straw and relative nitrogen yield, competitive factors in the intercrop and land use efficiency, in no-till (NT) system in the lowland Brazilian Cerrado. A randomized complete block experimental design was used in a 4×3+1 factorial arrangement with one control treatment, constituting 13 treatments, with four replications (n=4). The treatments comprised four tropical forages intercropped with maize: palisade grass (Urochloa brizantha cv. Marandu), congo grass (Urochloa ruziziensis), and the guinea grass cultivars Tanzânia and Áries (Panicum maximum cv. Tanzânia and Áries); three intercropping modalities: forage sown simultaneously in the maize rows, mixed with fertilizer; forage sown (broadcast) on the same day as maize sowing; and forage sown, mixed with top-dressed fertilizer, at the V4 stage of maize; and one control treatment (maize monoculture). Regardless of the type of tropical forage and intercropping modality, intercropping exhibited minimum competition between crops and did not interfere on the yield components and grain yield of fall-irrigated maize. In addition, it increased the amount of straw, and improved land use efficiency and relative nitrogen yield in comparison to mono-cropped maize. The best options were congo grass sown simultaneously in the maize rows and guinea grass cv. Tanzânia and guinea grass cv. Áries sown broadcast on total area, as they raised the shoot dry matter of maize and forage and land equivalent ratio. Congo grass sown simultaneously in the maize rows also raised the relative nitrogen yield. Keywords: lowland Brazilian Cerrado, Panicum, Urochloa, Zea Mays L.PEREIRA, F. C. L. B.; MELLO, L. M.

M.AVALIAÇÃO MORFOLÓGICA DO CONSÓRCIO DE MILHO OUTONAL IRRIGADO COM FORRAGEIRAS TROPICAIS 2 RESUMO O consórcio de milho outonal irrigado com forrageiras tropicais, pode elevar a quantidade de palhada e a produtividade relativa de nitrogênio, além de melhorar a eficiência de uso da terra, sem reduzir a produtividade de grãos. Objetivou-se avaliar o efeito de modalidades de implantação do consórcio de milho outonal irrigado com forrageiras tropicais sobre os componentes da produção, a produtividade relativa de nitrogênio, grãos e palhada, os fatoresde competição no consórcio e a eficiência de uso da terra, sob sistema plantio direto no Cerrado de baixa altitude. O delineamento experimental foi em blocos casualizados em esquema fatorial (4×3+1) com uma testemunha, constituindo 13 tratamentos com quatro repetições. Os tratamentos foram constituídos por quatro forrageiras: capim-marandu, capim-ruziziensis, capim-tanzânia e capim-áries; e três modalidades de consórcio das forrageiras com o milho: forrageira semeada simultaneamente na linha de semeadura, misturada com o adubo; forrageira semeada simultaneamente a lanço em área total no mesmo dia da semeadura do milho; e forrageira semeada a lanço misturada ao adubo de cobertura no estádio V4 do milho; e uma testemunha constituída pelo cultivo exclusivo do milho. Independente da forrageira e da modalidade de semeadura, o consórcio proporcionou mínima competição entre as culturas e não interfere nos componentes da produção e na produtividade de grãos de milho outonal irrigado, além de elevar a quantidade de palhada, melhorar a eficiência de uso da terra e a produtividade relativa de nitrogênio, em relação ao cultivo exclusivo do milho.

Получены сорбенты на основе природного материала глауконита для сбора нефти и нефтепродуктов с разных поверхностей. Глауконит относится к алюмосиликатным минералам и широко используется для очистки воды и почвы от различных поллютантов. Классификация позволила отобрать фракцию глауконита с размером частиц 0.045–0.1 мм, которая наиболее эффективна при сорбции нефтепродуктов. Для этого проводилась термическая активация и модифицирование сорбента органическими соединениями. Термообработка образцов глауконита осуществлялась при температурах 100, 600 и 1000 °С. Для придания ему гидрофобных свойств модифицировалистеариновой кислотой. При контакте сорбентов с водой (продолжительность 92 часа) установлено, что при массовой доле стеариновой кислоты 5 масс. % наблюдаются наименьшие потери массы у всех трех образцов. Краевой угол смачивания для сорбентов больше 90°, что привело к изменению состояния его поверхности. Полученные образцы не смачиваются водой и могут долгое время находиться на ее поверхности. Взаимодействие нефти и гидрофобного сорбента показало,что через семь минут частицы сорбента проникают в нефть, которая также имеет гидрофобную поверхность и может сорбировать на ней поверхностно-активное вещество, нанесенное на сорбент, что свидетельствует о сродстве стеариновой кислоты к нефти. Гранулированный сорбент, термически активированный при температуре 1000 °С и модифицированный целлюлозосодержащим компонентом, в течение 2 минут сорбировал нефть. Использование данного модификатора увеличило пористость сорбента, что и повлияло на скорость сорбции. ЛИТЕРАТУРА 1. Carmody O., Frost R., Xi Y., Kokot S.

Eating habits develop during the first years of a child's life, children learn what, when, and how much to eat through direct experience with food and by observing the eating habits of others. The aim of this study is to get a clear picture of the Eating program Healthy, starting from the planning, implementation, supervision, and evaluation as a case study of nutrition education; to get information about the advantages, disadvantages and effects of implementing a healthy eating program for children. This research was conducted through a case study with qualitative data analysed using Miles and Huberman techniques. Sample of children in Ananda Islāmic School Kindergarten. The results showed the Healthy Eating program could be implemented well, the diet was quite varied and could be considered a healthy and nutritious food. The visible impact is the emotion of pleasure experienced by children, children become fond of eating vegetables, and make children disciplined and responsible. Inadequate results were found due to the limitations of an adequate kitchen for cooking healthy food, such as cooking activities still carried out by the cook himself at the Foundation's house which is located not far from the school place; use of melamine and plastic cutlery for food; the spoon and fork used already uses aluminium material but still does not match its size; does not involve nutritionists.

In the COVID-19 pandemic scenario, parents need to be familiar with health literacy by applying clean and healthy living habits to their family members, especially those with early childhood. This study aims to explain parents' perceptions of health literacy for a clean and healthy behavior in their children during the COVID-19 pandemic. The method used in this study is a cross-sectional study involving 22 men and 62 female respondents. Respondent requirements were used in data analysis to determine parents' perceptions of health literacy and the efforts they have made to practice clean and healthy lifestyle in their children. The research findings show that knowing the health awareness of parents has an impact on a child's balanced lifestyle. Based on six measures of clean and healthy behavior for children, three indicators were determined in the category of discipline and high discipline: using clean water, using the toilet, and doing physical activity. The act of washing children's hands with soap indicators has a high discipline score and the use of masks in children has low discipline. If the use of masks is not disciplined by parents, exposure to COVID-19 in early childhood can be disrupted.

EFFICIENCY OF BIOESTIMULANTS IN THE MANAGEMENT OF WATER DEFICIT IN SOYBEAN CULTURE 2 ABSTRACT This work aimed to evaluate the physiological characteristics and grain yield of soybeans submitted to the application of different biostimulants based on macronutrients, micronutrients, amino acids, plant extracts and other substances and natural complexes. The experiment was developed at the Teaching, Research and Extension Farm (FEPE) of UniBRAS - Faculdade Rio Verde, Rio Verde - GO. The experimental design used was randomized blocks with four replications. In the treatments, 5 biostimulants were tested separately: T1) Amino acids; T2) Seaweed Extract; T3) Fulvic acids; T4) Phytohormones; T5) Nutrients and T6) Control. Biometric and physiological variables, the mass of 100 grains and grain yield were evaluated. Biometric and physiological data, the mass of 100 grains and grain yield were subjected to analysis of variance (at 5% probability) and significance cases were subjected to the mean test (Tukey at 5% probability), using the SISVAR® statistical software. The use of biostimulants promoted greater resilience in the water deficit, as well as significant physiological and productivity increases in the soybean culture, in addition to providing greater protection to the plant, showing the efficiency of the use of biostimulants in promoting greater capacity to support a period of water deficit. Keywords: Glycine max; hydrical stress; water potential.

São fatores biométricos determinantes para o conhecimento da qualidade e determinação da produtividade das forrageiras usadas como pastagens: altura de plantas, diâmetro e altura dos colmos e relação folha/colmo. Neste trabalho, objetivou-se avaliar as características biométricas do capim Sudão (Sorghum sudanense (Piper) Stapf), cultivar BRS Estribo, em três cortes de uniformização, sob diferentes lâminas de irrigação. O experimento foi conduzido no município de Santa Maria-RS, Brasil, em dois anos agrícolas: 2015/2016 e 2016/2017. O delineamento experimental utilizado foi blocos casualizados, composto por quatro blocos, com cinco tratamentos por bloco, mais a testemunha. Os tratamentos consistiram na aplicação de lâminas de irrigação suplementar equivalentes a: 25, 50, 75, 100 e 125% da evapotranspiração de referência (ETo). Foram avaliados: altura de plantas, diâmetro e altura dos colmos e a relação folha/colmo. Observou-se significância estatística para todos os fatores analisados, exceto para a relação folha/colmo. À medida que as lâminas de irrigação aumentaram até o tratamento com 100% da ETo, observou-se incrementos na altura das plantas e diâmetro e altura dos colmos, portanto, para potencializar o desenvolvimento desses fatores, recomenda-se que a demanda hídrica do capim Sudão seja integralmente suprida. Palavras chave: Sorghum sudanense (Piper) Stapf., altura de plantas, diâmetro de colmos, relação folha/colmo. MEZZOMO, W.; PEITER, M. X.; ROBAINA, A. D.; TORRES, R. R.; KIRCHNER, J. H.; PEREIRA, A. C. BIOMETRIC CHARACTERISTICS OF SUDAN GRASS (BRS ESTRIBO) UNDER DIFFERENT SUPPLEMENTAL IRRIGATION DEPTHS 2 ABSTRACT The use of pastures is the most economically viable way to feed beef/dairy cattle. The biometric plant factors: plant height, diameter and height of stems and leaf/stem ratio, are determining factors for quality assessment and determination of the productivity of forages used as pastures. In this work, the objective was to evaluate the biometric characteristics of Sudan grass (Sorghum sudanense (Piper) Stapf), cultivar BRS Estribo, in three uniformity cuts under different irrigation depths. The experiment was conducted in the municipality of Santa Maria-RS, Brazil, in two agricultural years: 2015/2016 and 2016/2017. The experimental design used was randomized blocks, composed of four blocks, with five treatments per block, plus the control treatment. The treatments consisted of the application of supplemental irrigation depths equivalent to: 25, 50, 75, 100, and 125% of the reference evapotranspiration (ETo). The following factors were evaluated: plant height, diameter and height of stems and leaf/stem ratio. Statistical significance was observed for all factors analyzed, except for the leaf/stem ratio. As the supplemental irrigation depths increased until treatment with 100% of ETo, increments in plant height and diameter and height of stems were observed; therefore, to enhance the development of these factors, it is recommended that the water requirements of Sudan grass be fully met. Keywords: Sorghum sudanense (Piper) Stapf., plant height, stem diameter, leaf/stem ratio.

International visitor surveys (IVS) are traditionally designed to provide destinations with marketing data and intelligence. The New Zealand Tourism Research Institute has been developing new approaches to IVS implementation and data collection in the Pacific Islands that can provide a much richer source of information [1]. The research outlined here is the first to utilise an IVS to explore the positioning of cuisine in the culinary identity of a destination – specifically, the cuisine of the Cook Islands. The Cook Islands is known primarily for its sun, sea and sand features, rather than its culinary attributes. Drawing on data mining of the Cook Islands IVS (2012–2016) and a web audit of destination websites and menus, this paper considers the positioning of food and food-related activities within the Pacific nation’s tourism experience. National tourism organisations are increasingly seeking competitive advantage by utilising their local cuisines as tourist attractions. Research suggests that distinctive local cuisines can act as both a tourism attraction, and as a means of shaping the identity of a destination [2, 3]. In addition to providing an important source of marketable images, local cuisine can also provide a unique experience for tourists. This reinforces the competitiveness and sustainability of the destination [2]. The cuisine of the Cook Islands has come up repeatedly in recommendations for how the country can grow its tourism revenue. Recommendations have been made to improve the food product on offer, develop a distinctive Cook Islands cuisine based on fresh, local produce, and to promote a Cook Islands cuisine experience [4, 5], and to use these to market the Cook Islands as a destination for local food tourism experiences [4]. Despite these recommendations, Cook Island cuisine features less prominently than stereotypical sun, sea, and sand marketing images, and little is known about tourists’ perceptions of and satisfaction with food and food-related activities [6]. Our research addresses this gap by mining IVS data to gain a deeper understanding of tourists’ experiences and perceptions of food in the Cook Islands and assessing whether local food can be positioned as means of creating a unique destination identity. Two methods were used to develop a picture of where food sits in the Cook Islands tourist experience: one focussed on tourist feedback; and the other focused on how food is portrayed in relevant online media. Analysis of all food-related data collected as part of the national IVS between 1 April 2012 and 30 June 2016 was conducted (N = 10,950). A web audit also focused on how food is positioned as part of the Cook Islands tourism product. After identifying the quantitative food-related questions in the IVS, satisfaction with these activities was analysed. Qualitative comments related to food experiences were also examined. The results suggest that participation in food-related activities is generally a positive feature of the visitor experience. The web-audit revealed, however, that food is not a salient feature in the majority of Cook Islands-related websites, and when food did feature, it tended to be oriented towards international cuisine with a ‘touch of the Pacific’ rather than specifically Cook Islands cuisine. This reinforced findings from the IVS data mining that Cook Islands food is presented as a generic tropical ‘seafood and fruit’ cuisine that, largely, lacks the defining and differentiating features of authentic Cook Island cuisine. High participation rates in food-related activities and overall positive evaluations by visitors emerged from the IVS data, yet a dearth of images and information on the country’s food suggests that the Cook Islands is not exploiting its cuisine and food experiences to their full potential. As a direct result of this secondary analysis of IVS data, which highlighted the importance of and potential for food-related activities, the Cook Islands Government is now actively addressing this gap by developing a range of food-related resources and information that can better link tourism to local cuisine. In addition to developing a greater presence of local food in online resources, the Cook Islands Tourism Corporation has also taken on board the messages from the IVS to drive the development of Takurua [7] – an initiative to develop and document local, traditional cuisine and share it with the world. This approach is part of a broader ongoing effort to differentiate the Cook Islands from other South Pacific destinations through its unique cultural attributes. Data mining and secondary analysis of IVS data has not been restricted to the identification of food-related opportunities. Secondary analysis of IVS data in the Pacific has also been used to investigate the impact of other niche markets such as events [8] and to gauge the impact of environmental incidents, for example Cyclone Pam in Vanuatu [9] and algal bloom in the Cook Islands [10], thus reinforcing that IVS data are a rich source of information and are indeed more than just numbers.

Carbon dioxide emission on peatland under oil palm plantation were highly varied probably due to many factors involved. The objectives of the research were to evaluate the effect of distance sampling from center of oil palm tree on Carbon dioxide flux, and to study the factors that cause variability of carbon dioxide flux on peatland under oil palm plantation. The study was conducted on peatland at Arang-Arang Village, Kumpek Ulu Sub-District, Muaro Jambi District, Jambi Province, on six year old oil palm plantation. The study was conducted in the form of observational exploratory. Emission measurements performed on 5 selected oil palm trees at points within 100, 150, 200, 250, 300, 350, and 400 cm from the center of trunk. Carbon dioxide flux was measured using (IRGA), Li-COR 820. The results showed that there is significant correlation between the distance of sampling from center of oil palm tree and Carbon dioxide flux. The farther distance from the tree, Carbon dioxide flux more decreased. Before applying fertilizer, variability of soil fertility was not significantly correlated with the flux of Carbon dioxide, so the difference of Carbon dioxide flux based on distance sampling can be caused by root distribution factor. After fertilizer application, variability of Carbon dioxide flux under the oil palm tree were beside affected by differences in root distribution, was also greatly influenced by fertilization.Keywords: Carbon dioxide flux, distance sampling, oil palm, peat, root-related respiration [How to Cite: Dariah A, F Agus, E Susanti and Jubaedah. 2013.Relationship between Sampling Distance and Carbon Dioxide Emission under Oil Palm Plantation.

Green gram (Vigna radiata) is considered the chief legume in Pakistan. Thus, current study was conducted to examine the ameliorating effect of phytohormones pre-treatments under salt stress on proteome profile of green gram by sodium-dodecyl-sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The soluble green gram seedlings proteins were resolved on 4% stacking and 12% resolving gels. The SDS-PAGE resolved 24 polypeptide bands ranging from 200 to 17kDa. Among these, 12 out of 24 bands of proteins were essentials house-keeping or growth proteins of green grams. While, 120, 114.6, 51.8, 29.1, and 22.8 kDa bands were over-expressed under 50 to 350mM salt with phytohormones treatments. The others 104.5 kDa, 99.8 kDa, 95.3 kDa, 91.0 kDa, 55 kDa, 46 kDa, and 17kDa bands were related to the GAᴣ, IAA, and SA induced tolerance. Overall 120 kDa, 114.6 kDa, 104.5 kDa, 99.8, 95.3 kDa, 51.8 kDa, 29.1 kDa and 22.8kDa bands were first time identified in the current study. The information retrieved from NCBI protein database, the resolved peptides were principally belonging to 7S and 8S vicilin, 2S, 8S, 11S, and 16.5S globulins. It is determined that seed priming with SA enhanced tolerance in green gram by rapidly synthesizing stress alleviating peptides.Key word: Cluster analysis, dendrogram, mungbean, salt stress, SDS-PAGEINTRODUCTIONVarious world-wide health concerning organization recommended the use of high graded plant protein such as legumes to prevent the risk of metabolic disorder (Hou et al., 2019). Legumes are most important protein crop on the earth. Among the legumes, the green gram is the major pulses. Its seeds are rich in superior quality storage protein, which account 85% of the total protein while, another 15% have not been broadly studied (Yi-Shen et al., 2018). The soluble storage protein comprises of 60% globulins, 25% albumin and 15% prolamins. Globulins are further divided into 3.4% basic-type (7S), 7.6% legumin-type (11S), and 89% vicilin-type (8S) (Mendoza et al., 2001; Itoh et al., 2006). Other than proteins, the green gram seeds also contain starch, fiber, phenolic compound, saponins, vitamins, calcium zinc, potassium, folate, magnesium, manganese and very low in fat that made it meager man’s meat (Hou et al., 2019). It is also a good source of green manure and fodder (El-Kafafi et al., 2015). Its root has ability to fix 30 to 50 Kg/ha atmospheric nitrogen in the soil which is essential for maintaining soil fertility (Chadha, 2010). The green gram is the valuable and the major Rabi pulse crop of Pakistan. Its cultivation area in 2016-2017 was about 179,000 hectares with seed yield of 130,000 tones. In comparison during 2017-2018, it was cultivated on 161,800 hectares land with 118,800 tones seed yield (GOP, 2018). One of the reasons of this 9% decrease in both land and productivity is the shortage of irrigated land due to soil salinity. The salinity induce oxidative bust in the mungbean cells, caused by responsive oxygen species (ROS) such as hydrogen peroxide, singlet oxygen, hydroxyl radical and superoxide radical. The ROS create hindrance in various metabolic processes of plant via interacting with macromolecules like proteins (Alharby et al., 2016). However, phytohormones like gibberellic acid (GAᴣ), indole acetic acid (IAA), and salicylic acid (SA) take part in the biosynthesis of salt tolerance proteins under salinity. These salt tolerance proteins acclimate plants under salinity stress. Application of biotechnology plays a significant role in agriculture (Khan et al., 2017). Therefore, production of particular proteins under salt stress is a specific response of cell which can be analyzed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). SDS-PAGE is the simple, valid, and cost-effective biochemical marker (Mushtaq et al., 2018). This marker has been widely used to determine the extent of evolutionary variations in crops (El-Kafafi et al., 2015).OBJECTIVES The present study was directed first time with the aim to investigate the toxic effect of sodium chloride (0-350 mM) and stress acclimation by pre-treatment of GAᴣ, IAA, and SA on the proteome profile of NM-92 cultivar of a Pakistani green gram.MATERIALS AND METHODSThe present study was replicated thrice in the plant laboratory of Department of Genetics, Faculty of Science, and University of Karachi. The seeds of mung bean cultivar NM-92 were acquired from National Agricultural Research Centre (NARC), Islamabad. These freshly collected 15 seedsˉ1 treatment / replication were divided into two sets. The first was named as sodium chloride (SC) stress treatments were imbibed in sterile distilled water (DW) whereas, second set soaked in gibberellic acid (GAᴣ) (BDH Chemicals, England), indole acetic acid (IAA) (Fluka, Switzerland), and salicylic acid (SA) (J.T. Baker, Holland) in the separate beaker for 24 hours under dark condition. After 24 hours, given ample time to both the sets at room temperature. After recovery, all 20 treatments were sown in the 150 X 30 mm sized petri-dishes containing 0, 50, 150, 250, and 350 millimolar (mM) sodium chloride solution (Fisher Scientific, UK) for 72 hours.Protein extraction: Protein extraction was done by taking 0.3g of seedlings in an ice chilled mortar and crushed by adding 600µL 0.2 M Tris-HCl buffer having pH 7.5 contained 5% SDS (w/v) and 5% 2-mercaptoethanol (v/v). The homogenate was incubated at 0oC for 30 min., boiled in the water bath for 3 min. at 100oC. Samples were centrifuged in Heraeus Biofuge D-37520, Germany for 30 min. at 8000 rpm. The protein supernatant was saved at below 0°C for quantitative and qualitative determination with minor modifications. The total soluble protein content of the samples was estimated via “Bovine Serum Albumin (BSA) standard curve” and explicit in µg protein milligramˉ1 fresh weight of mung seedlings.Bovine serum albumin standard curve (2000 μg/mL): Total protein standard curve was made by dissolving 0.05g of Bovine Serum Albumin (BSA) in 25mL of distilled water. Ten serial dilutions were made from 0.1 mL to 1mL by BSA solution then performed Lowry. A standard curve of total proteins was plotted by taking BSA absorbance at Y-axis and 2000 μg BSA / mL at X-axisSample preparation for SDS-PAGE: For qualitative assessment of total proteins; the 35μL of saved protein supernatant was combined with 15μL of sample diluting buffer (SDB). The SDB was made up of 0.0625 M Tris-HCl pH 6.8 with 2% of SDS, 10% of glycerol, 0.003% of bromophenol blue dye and 5% of 2-mercaptoethanol. Boil the 50μL protein SDB supernatant at 100oC in water bath for 3 min., centrifuged at 6000 rpm for 4 min. The supernatant was loaded on SDS-PAGE gel with the given formulae. The SDS- PAGE: Total proteins were fractionated via SDS-PAGE with 4% stacking and 12% resolving gel. The resolving gel of 12% was made by taking 6mL solution A, 1.8 mL 3 M Tris 1 M HCl buffer pH 8.8, 144μL 10% SDS, 5.74 mL sterile distilled water, 720μL 1.5% ammonium persulphate (APS) in deionized water and 10μL TEMED. While, stacking was composed of 1.25mL of solution A, 2.5mL of 0.5M Tris 1M HCl buffer pH 6.8, 100μL 10% SDS, 1.8 mL of distilled water, 500μL 1.5% APS and 12μL TEMED. Solution A was prepared by conjoining 30% acrylamide and 0.8% N, N’-methylene-bisacrylamide in deionized water. To avoid polymerization in the beaker; the prepared solution was quickly poured into the 3 mm thick gel plates after adding TEMED. The stacking was lined over resolving gel, then combs were inserted between the gel plates of SCIE-PLAS TV-100 separation system, UK, and allowed to polymerize for ½ an hour. After polymerization gel was placed in the tank which were filled with Tris-Glycine buffer (electrode buffer) pH 8.4 then combs were removed. The electrode buffer contained 0.3% Tris, 1.41% Glycine and 0.1% SDS in 2000mL d/w. The gel was pre-run for 15 min. at 60 volts and 120 mA currents. The prepared SDS-PAGE samples were loaded in wells with BlueStepTM Broad Range Protein Marker, AMRESCO, USA as standard and run at 60 volts & 120 mA for about 45 min. When samples entered in resolving gel, and then gave 100 volts and 200 mA currents for around 2.5 hours. Furthermore, electrophoresis was carried out at a constant watt.The Gel was washed with 30% ethanol on Uni Thermo Shaker NTS-1300 EYELA, Japan at the constant shaking for 30 min. Then gels were placed in 10% glacial acetic acid in 50% methanol solution (Fixative) for 24 hours. SDS Gel was stained until protein bands were visible thereat placed as 5% of Methanol in 7.5% acetic acid glacial solution to destain the bands background. SDS-PAGE stain composed of 0.125% coomassie brilliant blue R-250 dissolved in 40% of Methanol and 7% acetic acid glacial solution. The stain was stirred on Magnetic stirrer & hot plate M6/1, Germany for 6-10 hours before used. Photographs were taken by Sanyo digital camera VPC-T1284BL and bands were scored through numbering pattern. Gels preserved in 10% acetic acid solution at 4°C.Interpretation of bands and data analysis: The total soluble protein bands relative mobility calculated by below formulae and Dendrogram was constructed via SPSS v. 20Where,F=(Migrated distance of protein band)/(Migrated distance of dye front)Slop=(Log MW of protein marker lower limit band–log〖MW of protein marker upper limit band )/(RF protein marker lower limit band –RF of protein marker upper limit band)RESULTS:The total soluble proteins extracted from green gram were perceived by SDS-PAGE Blue StepTm broad range biochemical markers. The protein-based marker was used to evaluate the toxic effect of sodium chloride along with pre-treatments of GAᴣ, IAA, and SA on proteome assay. In the current work, seedlings total soluble proteome resolved 24 polypeptide bands ranging from 200 to 17.1 kDa were recognized by using SDS-PAGE. The figure 1 showed Dendrogram assay, which classified the 20 treatments of SC, GAᴣ, IAA and SA into two major clusters where, the cluster I was the largest one (figure 1). Cluster I consisted of 15 treatments that further divided into I-A, and I-B. The pre-treatments of SC50+SA, SC150+SA, SC250+SA, and SC350+IAA were grouped together into C-1 of sub-cluster I-A. The C-2 of sub-cluster I-A, pre-treatment SC350+SA was most diverse among 20 treatments. The C-1 treatments showed 99% homology when compared with each other while, it was 97% similar with C-2. The sub-cluster I-B comprised another 10 treatments, SC0+GAᴣ, SC50+GAᴣ, SC150+GAᴣ, SC250+GAᴣ, SC350+GAᴣ, SC0+IAA, SC50+IAA, SC150+IAA, SC250+IAA, and SC0+SA that were also 99% similar for total proteins. Sub-cluster I-B pre-treatments was exhibiting 94% homology with the sub-cluster I-A. The second cluster was the smallest one that was divided into two sub-clusters, II-A and II-B. The II-A was comprised of SC50, SC150, and SC250 while, sub-cluster II-B consisted of SC0 and SC350. Within each sub-cluster, pre-treatments expressed 99% homology whereas, II-A was 97 different from II-B. Furthermore, cluster I showed 75% similarities with cluster II (figure 1). The seedlings storage proteome profile of green gram was shown in table 1.The results showed that 120kDa, 114.6 kDa, 51.8 kDa, 29.1 kDa and 22.8 kDa proteins bands were not induced at 0 mM SC, GAᴣ, IAA, and SA. The table 1 depicted the presence of 120 kDa and 114.6 kDa bands only at 350 mM SC level with all phytohormones treatments. Similarly, 51.8 kDa protein bands were appearing at 150SC, 250SC and 350SC stress with phytohormones. Based on the information collected from the NCBI protein database, this peptide was related to the 8S globulin alpha subunits. The two other, 7S globulins sub-units having 29.1kDa and 22.8 kDa molecular weights bands were synthesized under 50mM, 150mM, 250mM, 350mM SC stress with phytohormones. Concerning protein polypeptide of molecular weight 104.5 kDa, 99.8 kDa, 91.0 kDa, 55.0 kDa, and 46.0 kDa, those were induced by GAᴣ, IAA and SA at 0 to 350 mM SC. While, 17kDa protein band was appearing in SA, and IAA treated samples and 95.3kDa band was only present in SA treatment. Other 12 protein bands were present in all treatments proved as house-keeping proteins of green gram (table 1).DISCUSSIONThe SDS-PAGE profiling for proteome is the reliable and applied biochemical approach that has been used as biochemical marker in various crop differentiation, and characterization. In the current study, first time SDS-PAGE was utilized to investigate the impact of GAᴣ, IAA, and SA pre-soaking on green gram under salt toxicity. The salt toxicity adversely affects all seed, seedling, and plant metabolic process (Parveen et al., 2016). At salt toxicity, the endogenous GAᴣ, IAA, and SA levels markedly decrease (El-Khallal et al., 2009). In such condition, exogenous application of GAᴣ, IAA, and SA enhance seedlings survival rate by increasing synthesis of seed storage proteins. Likewise, our Dendrogram characterization based on 20 treatments showed significant diversity under 0 to 350 mM SC stress. The salicylic acid treatments were grouped together except SC0+SA treatment, exhibiting a close relationship, which proved its acclimating role under salt stress. These findings will help plant breeder toward enhancing food quality and quantity of green gram in future breeding programme on saline sodic land.The SDS-PAGE assay revealed 200. kDa, 109.4 kDa, 77 kDa, 68 kDa, 49 kDa, 38 kDa, 33 kDa, 26 kDa, 24 kDa, 22 kDa, 21 kDa and 19 kDa fractions as essential green gram proteins. Among these, 68 kDa, 49 kDa, 33 kDa, 26 kDa, 24 kDa and 21 kDa peptides were seed biotinylated isoform protein (Riascos et al., 2009), putative NADH-ubiquinone oxidoreductase subunit H (Gostinčar et al., 2019), heat shock protein 33 (Hamidian et al., 2015), globulin protein, seed coat / maturation protein (Dhaubhadel et al., 2005), and protein for dimerization. While, 22 kDa proteins belonged to the class of prolamin alpha zein Z1C1_2, Z1C1_4, and Z1C1_8 precursors, and 19kDa peptide was related with Z1A1_2, Z1A2_2, and Z1B_6 precursors (Miclaus et al., 2011). Further, the 91 kDa peptide is sucrose synthase SS1 protein, and 77kDa protein is the NADPH-cytochrome P450 reductase (Wang et al., 2004). Also, the phosphatase-associated two other proteins having 46 and 55 kDa molecular weight were reported earlier in Mucuna pruriens. Hameed et al. (2012) and Malviya et al. (2008) found 55 and 46kDa peptides as 7S vicilin small sub-units and 17kDa as 11S globulins sub-unit in the studied Vigna radiata. Some other molecular weight proteome such as 68 kDa and 49kDa are 7S vicilin, 33kDa is 8S vicilin, 38 and 26kDa 8S globulins, 24kDa 11S globulins, and 22kDa 16.5S globulins. These proteins required for germination and seed establishment of green gram plant (Hameed et al., 2012).The vast accumulation of 23kDa and 22kDa peptides under salt stress by salicylic acid, were reported previously in the mangrove Bruguiera parviffora and Zea mays (El-Khallal et al., 2009). Correspondingly, El-Kafafi et al. (2015) reported the presence of 115kDa, 23kDa, and 22kDa bands in the salt tolerant lines of green gram. These proteomes induced under salt stress may play a pivotal part in the stress acclimation and osmotic adjustment. Similarly, the induction of 104 kDa and 100kDa MW polypeptide by SC stress in the salt tolerant genotypes of green gram indicated the functional role of phytohormones in various metabolic and defense response El-Kafafi et al. (2015); Alharby et al. (2016), El-Khallal et al. (2009), Qados (2010). Ali et al. (2007), Alharby et al. (2016), and El-Kafafi et al. (2015) observed 17kDa, 26kDa, 33kDa and 77kDa bands involving in salt tolerance and can be considered as a positive biochemical marker for salt stress. Further, 26 kDa MW peptide also functions as osmotin under the salt stress that involved in enhancing the accumulation of glycine betaine and proline in the cells. Hence, proteome assay of green gram showed that GAᴣ, IAA, and SA could regulate the expression of salt stress proteins that are anticipated to play a crucial part in the salt tolerance mechanism. Likewise, the involvement of phytohormones in the induction of changes in the proteome profile pattern was attributed to their part in managing cell division by regulating some genes of apical meristems.CONCLUSIONFinally, the results revealed the presence of the ten new bands with MW of 200kDa, 120 kDa, 114.6 kDa, 109.4kDa, 104.5kDa, 99.8kDa, 95.3kDa, 51.8kDa, 29.1kDa and 22.8kDa have not reported previously under salt stress with phytohormones treatments in green gram. Furthermore, it was observed that phytohormones alleviate the negative impact of salt stress on green gram by enhancing synthesis of salt defense polypeptides. Hence, higher accumulation of proteins was observed in salicylic acid treated seedlings. Thus, present work recommended the pre-soaking of phytohormones to overcome the toxic impact of sodium chloride on green gram. Further research is needed on a biomolecular level to reveal the mechanism of signalling pathways under sever salt stress.CONFLICT OF INTERESTBoth authors have declared that no disagreement of interest regarding this research.REFERENCES Alharby, H.

O experimento foi desenvolvido na Unidade de Pesquisa Hélio de Morais em Jaú – SP do Instituto Agronômico de Campinas, (IAC-Jaú). O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições constituídos pela combinação de quatro genótipos de cana-de-açúcar: RB867515, SP801842, CTC 6, RB92579 e dois manejos da cultura: manejo de irrigação por gotejamento subterrâneo e manejo de sequeiro. Ao longo do desenvolvimento do experimento foram avaliados os índices fisiológicos: condutância estomática, temperatura foliar, estimativa do conteúdo de clorofila aparente (SPAD) e índice de área foliar (IAF). Ao final do período experimental foram quantificados a produtividade de colmos e de açúcar. Os índices fisiológicos: condutância estomática (gs) e temperatura foliar, selecionaram com maior acurácia, genótipos de cana-de-açúcar tolerantes a deficiência hídrica e responsivos às tecnologias de irrigação. Os genótipos RB92579 e CTC6 foram menos tolerantes a deficiência hídrica em comparação com os genótipos RB867515 e SP80-1842, considerando a produtividade de colmos e de açúcar.

PHYSIOLOGICAL INDICES AND THE YIELD OF GENOTYPES OF SUGARCANE IN THE HANDLING OF DROUGHT AND DRIP IRRIGATION 2 ABSTRACT The objective of this work was to use physiological indices and yield of stalks and sugar of different genotypes in two contrasting water managements: irrigated and dry land management, to identify genotypes tolerant to water deficiency and responsive to irrigation. The experiment was developed at Hélio de Morais Research Unit in Jaú/SP, Brazil, from the Agronomic Institute of Campinas (IAC-Jaú). The experimental design was completely randomized block with four replications made up of the combination of four sugarcane genotypes: RB867515, SP801842, CTC 6, RB92579 and two crop managements: underground drip irrigation management and dry. During the development of the experiment, the physiological indexes were evaluated: stomatal conductance, leaf temperature, estimated apparent chlorophyll content (SPAD) and leaf area index (IAF). At the end of the experimental period the yield of stalks and sugar were quantified. The physiological indices: stomatal conductance (gs) and leaf temperature, selected with greater accuracy, sugarcane genotypes tolerant to water deficiency and responsive to irrigation technologies. The genotypes RB92579 and CTC6 were less tolerant to water deficit compared to genotypes RB867515 and SP80-1842, considering the yield of stalks and sugar. Keywords: Subsurface drip irrigation; Saccharum spp.; stomatal conductance; SPAD; leaf temperature.

Education in Oceania continues to reflect the embedded implicit and explicit colonial practices and processes from the past. This paper conceptualises a cultural approach to education and leadership appropriate and relevant to the Republic of the Marshall Islands. As elementary school leaders, we highlight Kanne Lobal, a traditional Marshallese navigation practice based on indigenous language, values and practices. We conceptualise and develop Kanne Lobal in this paper as a framework for understanding the usefulness of our indigenous knowledge in leadership and educational practices within formal education. Through bwebwenato, a method of talk story, our key learnings and reflexivities were captured. We argue that realising the value of Marshallese indigenous knowledge and practices for school leaders requires purposeful training of the ways in which our knowledge can be made useful in our professional educational responsibilities. Drawing from our Marshallese knowledge is an intentional effort to inspire, empower and express what education and leadership partnership means for Marshallese people, as articulated by Marshallese themselves. Introduction As noted in the call for papers within the Waikato Journal of Education (WJE) for this special issue, bodies of knowledge and histories in Oceania have long sustained generations across geographic boundaries to ensure cultural survival. For Marshallese people, we cannot really know ourselves “until we know how we came to be where we are today” (Walsh, Heine, Bigler & Stege, 2012). Jitdam Kapeel is a popular Marshallese concept and ideal associated with inquiring into relationships within the family and community. In a similar way, the practice of relating is about connecting the present and future to the past. Education and leadership partnerships are linked and we look back to the past, our history, to make sense and feel inspired to transform practices that will benefit our people. In this paper and in light of our next generation, we reconnect with our navigation stories to inspire and empower education and leadership. Kanne lobal is part of our navigation stories, a conceptual framework centred on cultural practices, values, and concepts that embrace collective partnerships. Our link to this talanoa vā with others in the special issue is to attempt to make sense of connections given the global COVID-19 context by providing a Marshallese approach to address the physical and relational “distance” between education and leadership partnerships in Oceania. Like the majority of developing small island nations in Oceania, the Republic of the Marshall Islands (RMI) has had its share of educational challenges through colonial legacies of the past which continues to drive education systems in the region (Heine, 2002). The historical administration and education in the RMI is one of colonisation. Successive administrations by the Spanish, German, Japanese, and now the US, has resulted in education and learning that privileges western knowledge and forms of learning. This paper foregrounds understandings of education and learning as told by the voices of elementary school leaders from the RMI. The move to re-think education and leadership from Marshallese perspectives is an act of shifting the focus of bwebwenato or conversations that centres on Marshallese language and worldviews. The concept of jelalokjen was conceptualised as traditional education framed mainly within the community context. In the past, jelalokjen was practiced and transmitted to the younger generation for cultural continuity. During the arrival of colonial administrations into the RMI, jelalokjen was likened to the western notions of education and schooling (Kupferman, 2004). Today, the primary function of jelalokjen, as traditional and formal education, it is for “survival in a hostile [and challenging] environment” (Kupferman, 2004, p. 43). Because western approaches to learning in the RMI have not always resulted in positive outcomes for those engaged within the education system, as school leaders who value our cultural knowledge and practices, and aspire to maintain our language with the next generation, we turn to Kanne Lobal, a practice embedded in our navigation stories, collective aspirations, and leadership. The significance in the development of Kanne Lobal, as an appropriate framework for education and leadership, resulted in us coming together and working together. Not only were we able to share our leadership concerns, however, the engagement strengthened our connections with each other as school leaders, our communities, and the Public Schooling System (PSS). Prior to that, many of us were in competition for resources. Educational Leadership: IQBE and GCSL Leadership is a valued practice in the RMI. Before the IQBE programme started in 2018, the majority of the school leaders on the main island of Majuro had not engaged in collaborative partnerships with each other before. Our main educational purpose was to achieve accreditation from the Western Association of Schools and Colleges (WASC), an accreditation commission for schools in the United States. The WASC accreditation dictated our work and relationships and many school leaders on Majuro felt the pressure of competition against each other. We, the authors in this paper, share our collective bwebwenato, highlighting our school leadership experiences and how we gained strength from our own ancestral knowledge to empower “us”, to collaborate with each other, our teachers, communities, as well as with PSS; a collaborative partnership we had not realised in the past. The paucity of literature that captures Kajin Majol (Marshallese language) and education in general in the RMI is what we intend to fill by sharing our reflections and experiences. To move our educational practices forward we highlight Kanne Lobal, a cultural approach that focuses on our strengths, collective social responsibilities and wellbeing. For a long time, there was no formal training in place for elementary school leaders. School principals and vice principals were appointed primarily on their academic merit through having an undergraduate qualification. As part of the first cohort of fifteen school leaders, we engaged in the professional training programme, the Graduate Certificate in School Leadership (GCSL), refitted to our context after its initial development in the Solomon Islands. GCSL was coordinated by the Institute of Education (IOE) at the University of the South Pacific (USP). GCSL was seen as a relevant and appropriate training programme for school leaders in the RMI as part of an Asia Development Bank (ADB) funded programme which aimed at “Improving Quality Basic Education” (IQBE) in parts of the northern Pacific. GCSL was managed on Majuro, RMI’s main island, by the director at the time Dr Irene Taafaki, coordinator Yolanda McKay, and administrators at the University of the South Pacific’s (USP) RMI campus. Through the provision of GCSL, as school leaders we were encouraged to re-think and draw-from our own cultural repository and connect to our ancestral knowledge that have always provided strength for us. This kind of thinking and practice was encouraged by our educational leaders (Heine, 2002). We argue that a culturally-affirming and culturally-contextual framework that reflects the lived experiences of Marshallese people is much needed and enables the disruption of inherent colonial processes left behind by Western and Eastern administrations which have influenced our education system in the RMI (Heine, 2002). Kanne Lobal, an approach utilising a traditional navigation has warranted its need to provide solutions for today’s educational challenges for us in the RMI. Education in the Pacific Education in the Pacific cannot be understood without contextualising it in its history and culture. It is the same for us in the RMI (Heine, 2002; Walsh et al., 2012). The RMI is located in the Pacific Ocean and is part of Micronesia. It was named after a British captain, John Marshall in the 1700s. The atolls in the RMI were explored by the Spanish in the 16th century. Germany unsuccessfully attempted to colonize the islands in 1885. Japan took control in 1914, but after several battles during World War II, the US seized the RMI from them. In 1947, the United Nations made the island group, along with the Mariana and Caroline archipelagos, a U.S. trust territory (Walsh et al, 2012). Education in the RMI reflects the colonial administrations of Germany, Japan, and now the US. Before the turn of the century, formal education in the Pacific reflected western values, practices, and standards. Prior to that, education was informal and not binded to formal learning institutions (Thaman, 1997) and oral traditions was used as the medium for transmitting learning about customs and practices living with parents, grandparents, great grandparents. As alluded to by Jiba B. Kabua (2004), any “discussion about education is necessarily a discussion of culture, and any policy on education is also a policy of culture” (p. 181). It is impossible to promote one without the other, and it is not logical to understand one without the other. Re-thinking how education should look like, the pedagogical strategies that are relevant in our classrooms, the ways to engage with our parents and communities - such re-thinking sits within our cultural approaches and frameworks. Our collective attempts to provide a cultural framework that is relevant and appropriate for education in our context, sits within the political endeavour to decolonize. This means that what we are providing will not only be useful, but it can be used as a tool to question and identify whether things in place restrict and prevent our culture or whether they promote and foreground cultural ideas and concepts, a significant discussion of culture linked to education (Kabua, 2004). Donor funded development aid programmes were provided to support the challenges within education systems. Concerned with the persistent low educational outcomes of Pacific students, despite the prevalence of aid programmes in the region, in 2000 Pacific educators and leaders with support from New Zealand Aid (NZ Aid) decided to intervene (Heine, 2002; Taufe’ulungaki, 2014). In April 2001, a group of Pacific educators and leaders across the region were invited to a colloquium funded by the New Zealand Overseas Development Agency held in Suva Fiji at the University of the South Pacific. The main purpose of the colloquium was to enable “Pacific educators to re-think the values, assumptions and beliefs underlying [formal] schooling in Oceania” (Benson, 2002). Leadership, in general, is a valued practice in the RMI (Heine, 2002). Despite education leadership being identified as a significant factor in school improvement (Sanga & Chu, 2009), the limited formal training opportunities of school principals in the region was a persistent concern. As part of an Asia Development Bank (ADB) funded project, the Improve Quality Basic Education (IQBE) intervention was developed and implemented in the RMI in 2017. Mentoring is a process associated with the continuity and sustainability of leadership knowledge and practices (Sanga & Chu, 2009). It is a key aspect of building capacity and capabilities within human resources in education (ibid). Indigenous knowledges and education research According to Hilda Heine, the relationship between education and leadership is about understanding Marshallese history and culture (cited in Walsh et al., 2012). It is about sharing indigenous knowledge and histories that “details for future generations a story of survival and resilience and the pride we possess as a people” (Heine, cited in Walsh et al., 2012, p. v). This paper is fuelled by postcolonial aspirations yet is grounded in Pacific indigenous research. This means that our intentions are driven by postcolonial pursuits and discourses linked to challenging the colonial systems and schooling in the Pacific region that privileges western knowledge and learning and marginalises the education practices and processes of local people (Thiong’o, 1986). A point of difference and orientation from postcolonialism is a desire to foreground indigenous Pacific language, specifically Majin Majol, through Marshallese concepts. Our collective bwebwenato and conversation honours and values kautiej (respect), jouj eo mour eo (reciprocity), and jouj (kindness) (Taafaki & Fowler, 2019). Pacific leaders developed the Rethinking Pacific Education Initiative for and by Pacific People (RPEIPP) in 2002 to take control of the ways in which education research was conducted by donor funded organisations (Taufe’ulungaki, 2014). Our former president, Dr Hilda Heine was part of the group of leaders who sought to counter the ways in which our educational and leadership stories were controlled and told by non-Marshallese (Heine, 2002). As a former minister of education in the RMI, Hilda Heine continues to inspire and encourage the next generation of educators, school leaders, and researchers to re-think and de-construct the way learning and education is conceptualised for Marshallese people. The conceptualisation of Kanne Lobal acknowledges its origin, grounded in Marshallese navigation knowledge and practice. Our decision to unpack and deconstruct Kanne Lobal within the context of formal education and leadership responds to the need to not only draw from indigenous Marshallese ideas and practice but to consider that the next generation will continue to be educated using western processes and initiatives particularly from the US where we get a lot of our funding from. According to indigenous researchers Dawn Bessarab and Bridget Ng’andu (2010), doing research that considers “culturally appropriate processes to engage with indigenous groups and individuals is particularly pertinent in today’s research environment” (p. 37). Pacific indigenous educators and researchers have turned to their own ancestral knowledge and practices for inspiration and empowerment. Within western research contexts, the often stringent ideals and processes are not always encouraging of indigenous methods and practices. However, many were able to ground and articulate their use of indigenous methods as being relevant and appropriate to capturing the realities of their communities (Nabobo-Baba, 2008; Sualii-Sauni & Fulu-Aiolupotea, 2014; Thaman, 1997). At the same time, utilising Pacific indigenous methods and approaches enabled research engagement with their communities that honoured and respected them and their communities. For example, Tongan, Samoan, and Fijian researchers used the talanoa method as a way to capture the stories, lived realities, and worldviews of their communities within education in the diaspora (Fa’avae, Jones, & Manu’atu, 2016; Nabobo-Baba, 2008; Sualii-Sauni & Aiolupotea, 2014; Vaioleti, 2005). Tok stori was used by Solomon Islander educators and school leaders to highlight the unique circles of conversational practice and storytelling that leads to more positive engagement with their community members, capturing rich and meaningful narratives as a result (Sanga & Houma, 2004). The Indigenous Aborigine in Australia utilise yarning as a “relaxed discussion through which both the researcher and participant journey together visiting places and topics of interest relevant” (Bessarab & Ng’andu, 2010, p. 38). Despite the diverse forms of discussions and storytelling by indigenous peoples, of significance are the cultural protocols, ethics, and language for conducting and guiding the engagement (Bessarab & Ng’andu, 2010; Nabobo-Baba, 2008; Sualii-Sauni & Aiolupotea, 2014). Through the ethics, values, protocols, and language, these are what makes indigenous methods or frameworks unique compared to western methods like in-depth interviews or semi-structured interviews. This is why it is important for us as Marshallese educators to frame, ground, and articulate how our own methods and frameworks of learning could be realised in western education (Heine, 2002; Jetnil-Kijiner, 2014). In this paper, we utilise bwebwenato as an appropriate method linked to “talk story”, capturing our collective stories and experiences during GCSL and how we sought to build partnerships and collaboration with each other, our communities, and the PSS. Bwebwenato and drawing from Kajin Majel Legends and stories that reflect Marshallese society and its cultural values have survived through our oral traditions. The practice of weaving also holds knowledge about our “valuable and earliest sources of knowledge” (Taafaki & Fowler, 2019, p. 2). The skilful navigation of Marshallese wayfarers on the walap (large canoes) in the ocean is testament of their leadership and the value they place on ensuring the survival and continuity of Marshallese people (Taafaki & Fowler, 2019; Walsh et al., 2012). During her graduate study in 2014, Kathy Jetnil-Kijiner conceptualised bwebwenato as being the most “well-known form of Marshallese orality” (p. 38). The Marshallese-English dictionary defined bwebwenato as talk, conversation, story, history, article, episode, lore, myth, or tale (cited in Jetnil Kijiner, 2014). Three years later in 2017, bwebwenato was utilised in a doctoral project by Natalie Nimmer as a research method to gather “talk stories” about the experiences of 10 Marshallese experts in knowledge and skills ranging from sewing to linguistics, canoe-making and business. Our collective bwebwenato in this paper centres on Marshallese ideas and language. The philosophy of Marshallese knowledge is rooted in our “Kajin Majel”, or Marshallese language and is shared and transmitted through our oral traditions. For instance, through our historical stories and myths. Marshallese philosophy, that is, the knowledge systems inherent in our beliefs, values, customs, and practices are shared. They are inherently relational, meaning that knowledge systems and philosophies within our world are connected, in mind, body, and spirit (Jetnil-Kijiner, 2014; Nimmer, 2017). Although some Marshallese believe that our knowledge is disappearing as more and more elders pass away, it is therefore important work together, and learn from each other about the knowledges shared not only by the living but through their lamentations and stories of those who are no longer with us (Jetnil-Kijiner, 2014). As a Marshallese practice, weaving has been passed-down from generation to generation. Although the art of weaving is no longer as common as it used to be, the artefacts such as the “jaki-ed” (clothing mats) continue to embody significant Marshallese values and traditions. For our weavers, the jouj (check spelling) is the centre of the mat and it is where the weaving starts. When the jouj is correct and weaved well, the remainder and every other part of the mat will be right. The jouj is symbolic of the “heart” and if the heart is prepared well, trained well, then life or all other parts of the body will be well (Taafaki & Fowler, 2019). In that light, we have applied the same to this paper. Conceptualising and drawing from cultural practices that are close and dear to our hearts embodies a significant ontological attempt to prioritize our own knowledge and language, a sense of endearment to who we are and what we believe education to be like for us and the next generation. The application of the phrase “Majolizing '' was used by the Ministry of Education when Hilda Heine was minister, to weave cultural ideas and language into the way that teachers understand the curriculum, develop lesson plans and execute them in the classroom. Despite this, there were still concerns with the embedded colonized practices where teachers defaulted to eurocentric methods of doing things, like the strategies provided in the textbooks given to us. In some ways, our education was slow to adjust to the “Majolizing '' intention by our former minister. In this paper, we provide Kanne Lobal as a way to contribute to the “Majolizing intention” and perhaps speed up yet still be collectively responsible to all involved in education. Kajin Wa and Kanne Lobal “Wa” is the Marshallese concept for canoe. Kajin wa, as in canoe language, has a lot of symbolic meaning linked to deeply-held Marshallese values and practices. The canoe was the foundational practice that supported the livelihood of harsh atoll island living which reflects the Marshallese social world. The experts of Kajin wa often refer to “wa” as being the vessel of life, a means and source of sustaining life (Kelen, 2009, cited in Miller, 2010). “Jouj” means kindness and is the lower part of the main hull of the canoe. It is often referred to by some canoe builders in the RMI as the heart of the canoe and is linked to love. The jouj is one of the first parts of the canoe that is built and is “used to do all other measurements, and then the rest of the canoe is built on top of it” (Miller, 2010, p. 67). The significance of the jouj is that when the canoe is in the water, the jouj is the part of the hull that is underwater and ensures that all the cargo and passengers are safe. For Marshallese, jouj or kindness is what living is about and is associated with selflessly carrying the responsibility of keeping the family and community safe. The parts of the canoe reflect Marshallese culture, legend, family, lineage, and kinship. They embody social responsibilities that guide, direct, and sustain Marshallese families’ wellbeing, from atoll to atoll. For example, the rojak (boom), rojak maan (upper boom), rojak kōrā (lower boom), and they support the edges of the ujelā/ujele (sail) (see figure 1). The literal meaning of rojak maan is male boom and rojak kōrā means female boom which together strengthens the sail and ensures the canoe propels forward in a strong yet safe way. Figuratively, the rojak maan and rojak kōrā symbolise the mother and father relationship which when strong, through the jouj (kindness and love), it can strengthen families and sustain them into the future. Figure 1. Parts of the canoe Source: https://www.canoesmarshallislands.com/2014/09/names-of-canoe-parts/ From a socio-cultural, communal, and leadership view, the canoe (wa) provides understanding of the relationships required to inspire and sustain Marshallese peoples’ education and learning. We draw from Kajin wa because they provide cultural ideas and practices that enable understanding of education and leadership necessary for sustaining Marshallese people and realities in Oceania. When building a canoe, the women are tasked with the weaving of the ujelā/ujele (sail) and to ensure that it is strong enough to withstand long journeys and the fierce winds and waters of the ocean. The Kanne Lobal relates to the front part of the ujelā/ujele (sail) where the rojak maan and rojak kōrā meet and connect (see the red lines in figure 1). Kanne Lobal is linked to the strategic use of the ujelā/ujele by navigators, when there is no wind north wind to propel them forward, to find ways to capture the winds so that their journey can continue. As a proverbial saying, Kanne Lobal is used to ignite thinking and inspire and transform practice particularly when the journey is rough and tough. In this paper we draw from Kanne Lobal to ignite, inspire, and transform our educational and leadership practices, a move to explore what has always been meaningful to Marshallese people when we are faced with challenges. The Kanne Lobal utilises our language, and cultural practices and values by sourcing from the concepts of jouj (kindness, love), kautiej (respect), and jouj eo mour eo (reciprocity). A key Marshallese proverb, “Enra bwe jen lale rara”, is the cultural practice where families enact compassion through the sharing of food in all occurrences. The term “enra” is a small basket weaved from the coconut leaves, and often used by Marshallese as a plate to share and distribute food amongst each other. Bwe-jen-lale-rara is about noticing and providing for the needs of others, and “enra” the basket will help support and provide for all that are in need. “Enra-bwe-jen-lale-rara” is symbolic of cultural exchange and reciprocity and the cultural values associated with building and maintaining relationships, and constantly honouring each other. As a Marshallese practice, in this article we share our understanding and knowledge about the challenges as well as possible solutions for education concerns in our nation. In addition, we highlight another proverb, “wa kuk wa jimor”, which relates to having one canoe, and despite its capacity to feed and provide for the individual, but within the canoe all people can benefit from what it can provide. In the same way, we provide in this paper a cultural framework that will enable all educators to benefit from. It is a framework that is far-reaching and relevant to the lived realities of Marshallese people today. Kumit relates to people united to build strength, all co-operating and working together, living in peace, harmony, and good health. Kanne Lobal: conceptual framework for education and leadership An education framework is a conceptual structure that can be used to capture ideas and thinking related to aspects of learning. Kanne Lobal is conceptualised and framed in this paper as an educational framework. Kanne Lobal highlights the significance of education as a collective partnership whereby leadership is an important aspect. Kanne Lobal draws-from indigenous Marshallese concepts like kautiej (respect), jouj eo mour eo (reciprocity), and jouj (kindness, heart). The role of a leader, including an education leader, is to prioritise collective learning and partnerships that benefits Marshallese people and the continuity and survival of the next generation (Heine, 2002; Thaman, 1995). As described by Ejnar Aerōk, an expert canoe builder in the RMI, he stated: “jerbal ippān doon bwe en maron maan wa e” (cited in Miller, 2010, p. 69). His description emphasises the significance of partnerships and working together when navigating and journeying together in order to move the canoe forward. The kubaak, the outrigger of the wa (canoe) is about “partnerships”. For us as elementary school leaders on Majuro, kubaak encourages us to value collaborative partnerships with each other as well as our communities, PSS, and other stakeholders. Partnerships is an important part of the Kanne Lobal education and leadership framework. It requires ongoing bwebwenato – the inspiring as well as confronting and challenging conversations that should be mediated and negotiated if we and our education stakeholders are to journey together to ensure that the educational services we provide benefits our next generation of young people in the RMI. Navigating ahead the partnerships, mediation, and negotiation are the core values of jouj (kindness, love), kautiej (respect), and jouj eo mour eo (reciprocity). As an organic conceptual framework grounded in indigenous values, inspired through our lived experiences, Kanne Lobal provides ideas and concepts for re-thinking education and leadership practices that are conducive to learning and teaching in the schooling context in the RMI. By no means does it provide the solution to the education ills in our nation. However, we argue that Kanne Lobal is a more relevant approach which is much needed for the negatively stigmatised system as a consequence of the various colonial administrations that have and continue to shape and reframe our ideas about what education should be like for us in the RMI. Moreover, Kannel Lobal is our attempt to decolonize the framing of education and leadership, moving our bwebwenato to re-framing conversations of teaching and learning so that our cultural knowledge and values are foregrounded, appreciated, and realised within our education system. Bwebwenato: sharing our stories In this section, we use bwebwenato as a method of gathering and capturing our stories as data. Below we capture our stories and ongoing conversations about the richness in Marshallese cultural knowledge in the outer islands and on Majuro and the potentialities in Kanne Lobal. Danny Jim When I was in third grade (9-10 years of age), during my grandfather’s speech in Arno, an atoll near Majuro, during a time when a wa (canoe) was being blessed and ready to put the canoe into the ocean. My grandfather told me the canoe was a blessing for the family. “Without a canoe, a family cannot provide for them”, he said. The canoe allows for travelling between places to gather food and other sources to provide for the family. My grandfather’s stories about people’s roles within the canoe reminded me that everyone within the family has a responsibility to each other. Our women, mothers and daughters too have a significant responsibility in the journey, in fact, they hold us, care for us, and given strength to their husbands, brothers, and sons. The wise man or elder sits in the middle of the canoe, directing the young man who help to steer. The young man, he does all the work, directed by the older man. They take advice and seek the wisdom of the elder. In front of the canoe, a young boy is placed there and because of his strong and youthful vision, he is able to help the elder as well as the young man on the canoe. The story can be linked to the roles that school leaders, teachers, and students have in schooling. Without each person knowing intricately their role and responsibility, the sight and vision ahead for the collective aspirations of the school and the community is difficult to comprehend. For me, the canoe is symbolic of our educational journey within our education system. As the school leader, a central, trusted, and respected figure in the school, they provide support for teachers who are at the helm, pedagogically striving to provide for their students. For without strong direction from the school leaders and teachers at the helm, the students, like the young boy, cannot foresee their futures, or envisage how education can benefit them. This is why Kanne Lobal is a significant framework for us in the Marshall Islands because within the practice we are able to take heed and empower each other so that all benefit from the process. Kanne Lobal is linked to our culture, an essential part of who we are. We must rely on our own local approaches, rather than relying on others that are not relevant to what we know and how we live in today’s society. One of the things I can tell is that in Majuro, compared to the outer islands, it’s different. In the outer islands, parents bring children together and tell them legends and stories. The elders tell them about the legends and stories – the bwebwenato. Children from outer islands know a lot more about Marshallese legends compared to children from the Majuro atoll. They usually stay close to their parents, observe how to prepare food and all types of Marshallese skills. Loretta Joseph Case There is little Western influence in the outer islands. They grow up learning their own culture with their parents, not having tv. They are closely knit, making their own food, learning to weave. They use fire for cooking food. They are more connected because there are few of them, doing their own culture. For example, if they’re building a house, the ladies will come together and make food to take to the males that are building the house, encouraging them to keep on working - “jemjem maal” (sharpening tools i.e. axe, like encouraging workers to empower them). It’s when they bring food and entertainment. Rubon Rubon Togetherness, work together, sharing of food, these are important practices as a school leader. Jemjem maal – the whole village works together, men working and the women encourage them with food and entertainment. All the young children are involved in all of the cultural practices, cultural transmission is consistently part of their everyday life. These are stronger in the outer islands. Kanne Lobal has the potential to provide solutions using our own knowledge and practices. Connie Joel When new teachers become a teacher, they learn more about their culture in teaching. Teaching raises the question, who are we? A popular saying amongst our people, “Aelon kein ad ej aelon in manit”, means that “Our islands are cultural islands”. Therefore, when we are teaching, and managing the school, we must do this culturally. When we live and breathe, we must do this culturally. There is more socialising with family and extended family. Respect the elderly. When they’re doing things the ladies all get together, in groups and do it. Cut the breadfruit, and preserve the breadfruit and pandanus. They come together and do it. Same as fishing, building houses, building canoes. They use and speak the language often spoken by the older people. There are words that people in the outer islands use and understand language regularly applied by the elderly. Respect elderly and leaders more i.e., chiefs (iroj), commoners (alap), and the workers on the land (ri-jerbal) (social layer under the commoners). All the kids, they gather with their families, and go and visit the chiefs and alap, and take gifts from their land, first produce/food from the plantation (eojōk). Tommy Almet The people are more connected to the culture in the outer islands because they help one another. They don’t have to always buy things by themselves, everyone contributes to the occasion. For instance, for birthdays, boys go fishing, others contribute and all share with everyone. Kanne Lobal is a practice that can bring people together – leaders, teachers, stakeholders. We want our colleagues to keep strong and work together to fix problems like students and teachers’ absenteeism which is a big problem for us in schools. Demetria Malachi The culture in the outer islands are more accessible and exposed to children. In Majuro, there is a mixedness of cultures and knowledges, influenced by Western thinking and practices. Kanne Lobal is an idea that can enhance quality educational purposes for the RMI. We, the school leaders who did GCSL, we want to merge and use this idea because it will help benefit students’ learning and teachers’ teaching. Kanne Lobal will help students to learn and teachers to teach though traditional skills and knowledge. We want to revitalize our ways of life through teaching because it is slowly fading away. Also, we want to have our own Marshallese learning process because it is in our own language making it easier to use and understand. Essentially, we want to proudly use our own ways of teaching from our ancestors showing the appreciation and blessings given to us. Way Forward To think of ways forward is about reflecting on the past and current learnings. Instead of a traditional discussion within a research publication, we have opted to continue our bwebwenato by sharing what we have learnt through the Graduate Certificate in School Leadership (GCSL) programme. Our bwebwenato does not end in this article and this opportunity to collaborate and partner together in this piece of writing has been a meaningful experience to conceptualise and unpack the Kanne Lobal framework. Our collaborative bwebwenato has enabled us to dig deep into our own wise knowledges for guidance through mediating and negotiating the challenges in education and leadership (Sanga & Houma, 2004). For example, bwe-jen-lale-rara reminds us to inquire, pay attention, and focus on supporting the needs of others. Through enra-bwe-jen-lale-rara, it reminds us to value cultural exchange and reciprocity which will strengthen the development and maintaining of relationships based on ways we continue to honour each other (Nimmer, 2017). We not only continue to support each other, but also help mentor the next generation of school leaders within our education system (Heine, 2002). Education and leadership are all about collaborative partnerships (Sanga & Chu, 2009; Thaman, 1997). Developing partnerships through the GCSL was useful learning for us. It encouraged us to work together, share knowledge, respect each other, and be kind. The values of jouj (kindness, love), kautiej (respect), and jouj eo mour eo (reciprocity) are meaningful in being and becoming and educational leader in the RMI (Jetnil-Kijiner, 2014; Miller, 2010; Nimmer, 2017). These values are meaningful for us practice particularly given the drive by PSS for schools to become accredited. The workshops and meetings delivered during the GCSL in the RMI from 2018 to 2019 about Kanne Lobal has given us strength to share our stories and experiences from the meeting with the stakeholders. But before we met with the stakeholders, we were encouraged to share and speak in our language within our courses: EDP05 (Professional Development and Learning), EDP06 (School Leadership), EDP07 (School Management), EDP08 (Teaching and Learning), and EDP09 (Community Partnerships). In groups, we shared our presentations with our peers, the 15 school leaders in the GCSL programme. We also invited USP RMI staff. They liked the way we presented Kannel Lobal. They provided us with feedback, for example: how the use of the sail on the canoe, the parts and their functions can be conceptualised in education and how they are related to the way that we teach our own young people. Engaging stakeholders in the conceptualisation and design stages of Kanne Lobal strengthened our understanding of leadership and collaborative partnerships. Based on various meetings with the RMI Pacific Resources for Education and Learning (PREL) team, PSS general assembly, teachers from the outer islands, and the PSS executive committee, we were able to share and receive feedback on the Kanne Lobal framework. The coordinators of the PREL programme in the RMI were excited by the possibilities around using Kanne Lobal, as a way to teach culture in an inspirational way to Marshallese students. Our Marshallese knowledge, particularly through the proverbial meaning of Kanne Lobal provided so much inspiration and insight for the groups during the presentation which gave us hope and confidence to develop the framework. Kanne Lobal is an organic and indigenous approach, grounded in Marshallese ways of doing things (Heine, 2002; Taafaki & Fowler, 2019). Given the persistent presence of colonial processes within the education system and the constant reference to practices and initiatives from the US, Kanne Lobal for us provides a refreshing yet fulfilling experience and makes us feel warm inside because it is something that belongs to all Marshallese people. Conclusion Marshallese indigenous knowledge and practices provide meaningful educational and leadership understanding and learnings. They ignite, inspire, and transform thinking and practice. The Kanne Lobal conceptual framework emphasises key concepts and values necessary for collaborative partnerships within education and leadership practices in the RMI. The bwebwenato or talk stories have been insightful and have highlighted the strengths and benefits that our Marshallese ideas and practices possess when looking for appropriate and relevant ways to understand education and leadership. Acknowledgements We want to acknowledge our GCSL cohort of school leaders who have supported us in the development of Kanne Lobal as a conceptual framework.

This study aimed to explore the perceived barriers to physical activity among college students Study Design: Qualitative research design Eight focus group discussions on 67 college students aged 18-24 years (48 females, 19 males) was conducted on College premises. Data were analysed using inductive approach. Participants identified a number of obstacles to physical activity. Perceived barriers emerged from the analysis of the data addressed the different dimensions of the socio-ecological framework. The result indicated that the young adults perceived substantial amount of personal, social and environmental factors as barriers such as time constraint, tiredness, stress, family control, safety issues and much more. Understanding the barriers and overcoming the barriers at this stage will be valuable. Health professionals and researchers can use this information to design and implement interventions, strategies and policies to promote the participation in physical activity. This further can help the students to deal with those barriers and can help to instil the habit of regular physical activity in the later adult years.

Land cover and land use are highly visible indicators of climate change and human disruption to natural processes. While land cover is frequently monitored over a large area using satellite data, ground-based reference data is valuable as a comparison point. The NASA-funded GLOBE Observer (GO) program provides volunteer-collected land cover photos tagged with location, date and time, and, in some cases, land cover type. When making a full land cover observation, volunteers take six photos of the site, one facing north, south, east, and west (N-S-E-W), respectively, one pointing straight up to capture canopy and sky, and one pointing down to document ground cover. Together, the photos document a 100-meter square of land. Volunteers may then optionally tag each N-S-E-W photo with the land cover types present. Volunteers collect the data through a smartphone app, also called GLOBE Observer, resulting in consistent data. While land cover data collected through GLOBE Observer is ongoing, this paper presents the results of a data challenge held between June 1 and October 15, 2019. Called “GO on a Trail,” the challenge resulted in more than 3,300 land cover data points from around the world with concentrated data collection in the United States and Australia. GLOBE Observer collections can serve as reference data, complementing satellite imagery for the improvement and verification of broad land cover maps. Continued collection using this protocol will build a database documenting climate-related land cover and land use change into the future.

Abstract Background Water resources development promotes agricultural expansion and food security. But are these benefits offset by increased infectious disease risk? Dam construction on the Senegal River in 1986 was followed by agricultural expansion and increased transmission of human schistosomes. Yet the mechanisms linking these two processes at the individual and household levels remain unclear. We investigated the association between household land use and schistosome infection in children. Methods We analyzed cross-sectional household survey data (n = 655) collected in 16 rural villages in August 2016 across demographic, socio-economic and land use dimensions, which were matched to Schistosoma haematobium (n = 1232) and S. mansoni (n = 1222) infection data collected from school-aged children. Mixed effects regression determined the relationship between irrigated area and schistosome infection presence and intensity. Results Controlling for socio-economic and demographic risk factors, irrigated area cultivated by a household was associated with an increase in the presence of S. haematobium infection (odds ratio [OR] = 1.14; 95% confidence interval [95% CI]: 1.03–1.28) but not S. mansoni infection (OR = 1.02; 95% CI: 0.93–1.11). Associations between infection intensity and irrigated area were positive but imprecise (S. haematobium: rate ratio [RR] = 1.05; 95% CI: 0.98–1.13, S. mansoni: RR = 1.09; 95% CI: 0.89–1.32). Conclusions Household engagement in irrigated agriculture increases individual risk of S. haematobium but not S. mansoni infection. Increased contact with irrigated landscapes likely drives exposure, with greater impacts on households relying on agricultural livelihoods.

I examined variation in community structure, species richness, biomass and abundance of Coprini dung beetles from 45 trapping sites in meadows, 35-year-old secondary forests and primary forests in tropical, high-elevation karst ecosystems of Puluong Nature Reserve, Thanh Hoa Province. My main aim was to explore community response to the influence of land use change. By comparing the structure and community attributes of the beetles between 35-year-old secondary forests and primary forests, I expected to give indications on the conservation value of the old secondary forests for beetle conservation. Community structure significantly differed among land-use types. Species richness, abundance and biomass were significantly higher in forest habitats than in meadows. The cover of ground vegetation, soil clay content and tree diameter are important factors structuring Coprini communities in karst ecosystems of Pu Luong. The secondary forests, after 35 years of regrowth showed similarities in species richness, abundance and biomass to primary forests. This gives hope for the recovery of Coprini communities during forest succession. Keywords: Coprini, dung beetles, karst ecosystems, land use change, Pu Luong. References: [1] I. Hanski, Y.

D., Lyck, J., Mathiesen, A., & Nilsson, I. (1998). Wandel Sea Basin, eastern North Greenland. Geology of Greenland Survey Bulletin, 180, 55-62. https://doi.org/10.34194/ggub.v180.5086 _______________ The Wandel Sea Basin in eastern North Greenland is the northernmost of a series of fault-bounded Late Palaeozoic – Early Tertiary basins exposed along the eastern and northern margin of Greenland (Fig. 1). The basin and the surrounding shelf areas are located in a geologically complex region at the junction between the N–S trending Caledonian fold belt in East Greenland and the E–W trending Ellesmerian fold belt in North Greenland, and along the zone of later, Tertiary, continental break-up. The Wandel Sea Basin started to develop during the Carboniferous as a result of extension and rifting between Greenland and Norway, and Greenland and Spitsbergen (Håkansson & Stemmerik 1989), and was an area of accumulation during the Early Carboniferous – Early Tertiary period. Two main epochs of basin evolution have been recognised during previous studies of the basin fill: an early (late Palaeozoic – early Triassic) epoch characterised by a fairly simple system of grabens and half-grabens, and a late (Mesozoic) epoch dominated by strike-slip movements (Håkansson & Stemmerik 1989). The Mesozoic epoch only influenced the northern part of the basin, north of the Trolle Land fault zone (Fig. 1). Thus the northern and southern parts of the basin have very different structural and depositional histories, and accordingly different thermal histories and hydrocarbon potential. This paper summarises the results of a project supported by Energy Research Program (EFP-94), the purpose of which was to model the Wandel Sea Basin with special emphasis on hydrocarbon potential and late uplift history, and to provide biostratigraphic and sedimentological data that could improve correlation with Svalbard and the Barents Sea. It is mainly based on material collected during field work in Holm Land and Amdrup Land in the south-eastern part of the Wandel Sea Basin during 1993–1995 with additional data from eastern Peary Land (Stemmerik et al. 1996). Petroleum related field studies have concentrated on detailed sedimentological and biostratigraphic studies of the Carboniferous–Permian Sortebakker, Kap Jungersen, Foldedal and Kim Fjelde Formations in Holm Land and Amdrup Land (Fig. 2; Døssing 1995; Stemmerik 1996; Stemmerik et al. 1997). They were supplemented by a structural study of northern Amdrup Land in order to improve the understanding of the eastward extension of the Trolle Land fault system and possibly predict its influence in the shelf areas (Stemmerik et al. 1995a; Larsen 1996). Furthermore, samples for thermal maturity analysis and biostratigraphy were collected from the Mesozoic of Kap Rigsdagen and the Tertiary of Prinsesse Thyra Ø (Fig. 1).
