Information on the first findings of Gaillona rosea (Roth) Athanasiadis 2016:814 (Aglaothamnion roseum (Roth) Maggs & L’Hardy-Halos 1933:522) in the Russian part of the South-Eastern Baltic is given. Samples of algae in the Russian part of the South-Eastern Baltic along the coast of the Kaliningrad region at depths of 1–15 m were collected by diving method on the north coast of the Sambian Peninsula near Cape Taran and Cape Gvardeysky at the stations confined to hard ground. First samples of G. rosea collected from drifting mats of perennial algae Furcellaria lumbricalis and Polysiphonia fucoides were first registered along the west and north coast of the Sambian Peninsula (Cape Taran) at depths of 1.5–7 m in autumn 2015. The finding of the species in 2015 on the west coast of the Sambian Peninsula is the first registration for the coast of the Gdansk Bay. In July 2016, the species was found in samples at Cape Taran at a depth of 0.5 m. The length of the thalli does not exceed 3 cm. The species was registered with F. lumbricalis and P. fucoides, both in attached communities and in drifting mats. G. rosea is quite common in the Baltic Sea, with the exception of the Gdansk Bay and the northernmost part of the Baltic Sea, where the salinity is low. There is no data available on the abundance of the species in the adjacent Lithuanian waters. The species is rarely registered in the Russian part of the South-Eastern Baltic, and therefore G. rosea is rare in the entire South-Eastern Baltic Sea.

Full textAbstract:
Following the accident of the oil tanker ‘Prestige’, we surveyed the large scale fuel deposition patterns on the Cantabrian shore (northern Spain) covering three regions (from west to east): (i) Asturias, west of Cape Peñas (24 segments surveyed); (ii) Asturias, east of Cape Peñas (33 segments surveyed); and (iii) Cantabria (also east of Cape Peñas, 256 segments surveyed). Fuel arrived to the Cantabrian Coast as a single oil wave which was more intense to the east than to the west of Cape Peñas. The mean percentage of coast length affected was 25, 41 and 15% in western Asturias, eastern Asturias and Cantabria, respectively. However, less than 10% of the substrate was covered by fuel in oiled patches, thus the impact was moderate. We conclude that these patterns are consistent with fuel transport by the Iberian Poleward Current, a hydrographic feature typical of this region during winter.

. The features of coastal destruction on two key areas of the Sea of Okhotsk: Nabil-Lunsky and Nevelsky, are examined, using materials from remote sensing of the Earth. Section significantly different in natural conditions. The analysis of high-resolution satellite images of different times showed that in the Okhotsk sea (Nabil-Lunsky site) a significant factor affecting the dynamics of the coasts is the migration of cuspate bars and storm deformations. Morphologically, cuspate bars are large accumulative wave-like bodies with a period along the coast of about 350–500 m and an amplitude along the normal to the coast of 50–80 m. Cuspate bars s are known to slowly migrate in the direction of the coastal sediment flow. It was found that the average abrasion rate of the beach scarp according to the results of decoding different-time (1983–2010) satellite images and aerial photographs within the Nabil-Lunsky site was from 0.0 to 0.44 m/year. In the Nevel Strait, stability of the west coast is facilitated by wide watts and marches. The eastern coast (Sakhalin Island) in the area of Cape Ouangi is steep coast (slope is greater than 0.03), which favors the marginal erosion. Within the boundaries of the studied areas, the mean annual rate of abrasion was estimated. According to the results of deciphering the satellite images of the Cape Kamennyi area, it was found that the accumulative coasts from 1968 to 2006 were in relatively stable condition, and the abrasion-denudation shore at the seabed end of the cape was subjected to abrasion at speeds of 0.05–0.1 m/year

Full textAbstract:
Cape anchovy Engraulis encrasicolus is an ecologically and economically important pelagic fish species occurring along the coast of South Africa. A recent eastward shift in Cape anchovy distribution indicates that environmental conditions are becoming more favorable for the species on the east coast. This shift is particularly important in the sheltered Algoa Bay region, a nursery area for fish larvae. However, the relatively low productivity of the Agulhas Current Large Marine Ecosystem on the eastern coast of South Africa may result in an anchovy population in poorer nutritional condition and with slower growth rates than the west coast population. Using otolith and nucleic acid analyses, the growth rates of anchovy larvae from the western and southeastern coasts of South Africa were compared. The otolith analysis results indicated that, at any given age, individual growth rates for anchovy larvae were higher on the southeast coast than on the west coast. The RNA:DNA values also indicated that instantaneous growth rates of anchovy larvae were higher in Algoa Bay than on the west coast. At the time of sampling, chlorophyll and zooplankton productivity were higher at sampling sites in Algoa Bay than sites on the west coast, potentially due to favorable oceanographic features in the bay. As such, the results suggest that Algoa Bay is a suitable and potentially favorable nursery area for the early stages of anchovy, highlighting the importance of separate management of the southeast coast region in a changing world.

Full textAbstract:
The growth and accumulation of macroalgae in estuaries are a common sight throughout the world (Boyer and Fong, 2005). Because macroalgae establish such complex but important links with other components within an estuary, it is essential to know which variables control and regulate their occurrences. The type of algae that will occur in an estuary depends however, on the physical and chemical features of the particular estuary (Lobban and Harrison, 1994). The focus of this study was to document and provide a listing of algae from estuaries around the Eastern Cape coast of South Africa and describe the communities which form within each estuarine habitat. The questions posed were: Do algae assemblages differ in estuaries with different environmental conditions? Are different plant communities inhabited by different algae communities? Also, are algae diverse in estuaries that are in a pristine condition? The estuaries were Mngazana, Ngqusi/Nxaxo, Mtati, Mpekweni, East Kleinemonde, West Kleinemonde, Kariega, Bushmans, Kowie and the Sundays estuary. Percentage cover surveys were conducted and environmental parameters recorded to determine community structure of algae and their environmental tolerances. A total of 49 different macroalgal species were identified from 11 estuaries, which were dominated by Chlorophytes (23 species) and Rhodophytes (17 species). The Ochrophytes consisted of 10 species. The highest number of species recorded was 29 at the Bushmans estuary (March 2009), while the lowest number (4 species) was recorded at Mtati (October 2008). Common Chlorophytes found included Ulva prolifera, Chaetomorpha linum and Codium tenue. In the Division Ochrophyta, species from the Genus Ectocarpus were the most common. Of the red algae filamentous reds, Polysiphonia incompta and Polysiphonia kowiensis were the common algae found at estuaries. Salinity (p= 0.029861; n= 49) and temperature (p= 0.037641; n= 49) were the driving environmental parameters of estuaries and significantly influenced richness of species. In ordination analyses, patterns of biogeographic distribution were noticeable and were described by salinity. Four gradients caused by salinity were therefore found – which is inversely correlated to water clarity. Moreover, a clear split between temporarily open/closed and the permanently open estuaries was observed. Samples grouped into four communities presumably based on the similarity in conditions of estuaries. Within each estuarine community and major type of estuary there was a range of environmental conditions. However, the macroalgae within each community may not have been colonists of or found in greatest abundances in the estuaries of these communities per se, but may have grouped together in this manner based on the optimum growing conditions for them. Also, specific algal groups were not directly determined by the type of estuary they were found in; they were driven by environmental ranges rather. The results therefore support hypothesis one which states species distribution and diversity differ and are influenced by environmental gradients of the estuary. Although close species and habitat relationships were apparent from the ordination analyses, providing support for hypothesis two which states “Different plant communities in estuaries will be inhabited by different macroalgae communities”, the evidence was not substantial enough to provide sufficient support for the hypothesis. Lastly, the hypothesis “Macroalgae are diverse in estuaries that are in a pristine condition” was not accepted as highest species numbers were found in estuaries of greatest anthropogenic disturbance (e.g. Bushmans estuary) and not in estuaries which where ecologically more natural (e.g. Mtati estuary). By doing monthly macroalgal sampling over a period of one year for example one would obtain greater information of biodiversity, and patterns of macroalgal seasonality may be uncovered as well. This is an area of reasearch which needs to be investigated in the future as it would greatly add to the understanding of the role macroalge have in an estuarine environment.

Full textAbstract:
Many of the larger estuaries along the South African coastline are highly degraded due to human impacts, highlighting the need to conserve pristine systems. There are approximately 100 micro-estuaries along our coastline which have not yet been identified or classified and hence their ecological functioning is unknown. The aim of this study was to identify and classify micro-estuaries along the Eastern Cape coast. Specific objectives of the study were to: 1) map the distribution of estuarine habitats in a selection of micro-estuaries and assess changes over time; 2) measure the physico-chemical characteristics of the micro-estuaries in the field; 3) investigate the distribution of vegetation, identify macrophyte species and habitat integrity and classify the micro-estuaries sampled using abiotic and botanical characteristics. A total of 30 systems were identified of which 10 were selected for sampling which took place seasonally (2015-2016). A relationship between open water surface area and short term rainfall was only evident in Cunge, Sandy Bottom and Ichabana. In the field it was observed that after heavy rainfall, open water surface area increased and mouth breaching occurred. Salinity was the only water column characteristic that showed differences; salinity increased in response to over wash events. Sand was dominant in all systems and there were no differences in sediment characteristics. A total of 8 macroalgal species, 16 estuarine macrophyte species, six freshwater species and 72 riparian plant species were found. Seed bank reserves were low in all systems despite them being vegetated. Only abiotic characteristics were used for classification using Principle Components Analysis since there were no botanical differences between systems. Micro-estuaries were larger (> 0.03 ha), had a higher salinity (oligohaline, mesohaline and polyhaline conditions) and a constant water body. Micro-outlets were smaller (< 0.03 ha), had a lower salinity (oligohaline conditions were most common) and showed periods of drying. Five micro-estuaries (Shelbertsstroom, Kwesani, Cunge, Mtwendwe and Mtendwe) and five micro-outlets (Stromatolite, Sandy Bottom, Ichabana, Palm Tree and Black Rock) were classified. This study has shown that the micro-estuaries along the Eastern Cape coast are pristine (i.e. intact riparian zone and catchment), untouched and highly dynamic systems (i.e. great variation in water surface area and mouth condition) highlighting their need for protection.

Full textAbstract:
The project was initiated by Eastern Cape Parks (ECP) as a request for the construction of inventories of priority species and their population levels inside three nature reserves on the Eastern Cape Wild Coast, South Africa, and to develop a strategic management plan to manage these natural resources in each reserve. Thirty key species were identified by local communities in and around Dwesa-Cwebe, Silaka and Mkambati Nature Reserves through community workshops. For forested areas belt transects of 100 m x 6 m where used. The basal circumference of key tree species within the belt transect was measured as well as the height of saplings (height < 150 m). Tree species were categorized based on densities, size class distribution (SCD) curves and values, and spatial grain. For grassland areas straight transects of 200 m long were used, along which ten 3 m x 3 m quadrates were placed at 20 m intervals. Within each grassland transect the height of herbs or tuft diameter of grasses was recorded and percentage cover estimated. Grassland species were categorized based on density, SCD curves and percentage cover. All species were placed into harvesting categories based on analysed ecological data that was collected in the field. Category 1 species were very rare or not found in the reserve and it was recommended that species be conserved and monitored. Category 2 species had low densities in the reserve indicating declining populations and was suggested that these be monitored and not harvested. Category 3 species had high densities and have potential for harvesting with strict limitations. Category 4 species were most abundant with very high densities and can be harvested within management guidelines. These categories were grouped further using social and ecological data such as harvesting risk, frequency of collection, use value and number of uses. This highlighted which species have conservation priority within each category and a decision can be made as to how intense or limited extraction should be. By incorporating GIS the distribution of each species was looked at and harvesting and non-harvesting zones established to determine where species can be extracted. Monitoring plans must consider the quantity of plant material collected, fire regimes, optimal harvesting rates and harvesting zones, and be able to pick up changes in populations. Also, it is important that the community be involved in conserving and monitoring these species. Adaptive monitoring and management must be used to steer harvesting practices in the Wild Coast reserves. This allows for the development of harvesting practices through ‘learning by doing’, and the evolution of good questions to guide monitoring decisions

Full textAbstract:
An under-reported consequence of the democratic transition is the impact on land management (LM) within communal areas of South Africa (SA).Yet land is an essential natural resource, both for the survival and prosperity of humanity, and for the maintenance of all terrestrial ecosystems (FAO&UNEP,1997.)This study focuses on land management in the Wild Coast with special reference to indigenous people in Coffee Bay.Using the concept of the land management paradigm, the study adopts an intensive research design for the analysis and interpretation of data.The study aims to examine how land as a 'resource'is managed by the local indigenous people with special reference to wether it is moving towards or away from sustainability.The study discusses LM in the rural-built up environment with emphasis on land based activities, land tenure, gender issues,indigenous knowledge systems, changes in land use and degradation.The study looks at the indigenous people's participation in the new LM policy formation as predetermined by the grand scheme of democratization and decentralization.It highlights that indigenous knowledge systems are at the centre in rural sustainable LM, and equity in land issues forms another breakthrough for communal tenure system in the new SA.Indigenous people's views in policy formulation are not necessarily matched with national policy objectives due to poor public consultation.In general, the study provides an understanding of how indigenous people grapple with new policy changes in LM, to ensure sustainable land management in the rural South Africa

Full textAbstract:
It is evident that natural fish stocks are in rapid decline and that millions of people around the world rely on these resources for food and for securing a livelihood. This has brought many social scientists, biologists and fisheries experts to acknowledge that communities need to take more control in managing their natural resources. The paradigm shift in fisheries management from a top-down resource orientated control to a participatory people-centred control is now being advocated in many maritime nations in facilitating community-based natural resource management. At the heart of these projects is the establishment of institutions and social networks that allow for clear communication and information sharing, based on scientific data and traditional knowledge which ultimately allow empowered communities to collectively manage their resources in partnership with government, market actors and many other stakeholders. Central to the problem is the issue of access rights. In many situations where co-management of natural resources through community-government partnerships is advocated, the failure of coastal states to provide adequate legislature and regulatory frameworks has jeopardised such projects. A second issue is the failure of many states to provide adequate investments in social and human capital which will enable communities to become the primary stakeholder in the co-management of their natural resources. Whilst investments like capacity building, education, skills training and development, communications and institution building can initially require high financial investments, the regulatory costs for monitoring, controlling and surveying fish stocks along the coastline will go down as communities take ownership of their resources under sustainable awareness. The main unit of investment therefore is social capital which allows for the increase in trust, cooperativeness, assertiveness, collective action and general capabilities of natural resource governance. High levels of social capital require good social relations and interactions which ultimately create a social network of fishers, community members and leaders, government officials, market players, researchers and various other stakeholders. Co-management thus has an inherent network structure made up of social relations on a horizontal scale amongst community members as well as on a vertical scale with government and fisheries authorities. These bonding relations between people and the bridging relations with institutions provide the social capital currency that allows for a successful co-management solution to community-based natural resource governance. The South African coastline is home to thousands of people who harvest the marine resources for food security and securing a basic income. Fishing is a major cultural and historical component of the livelihoods of many people along the coastline, particularly along the Wild Coast of South Africa located on its South-eastern shoreline. Due to the geopolitical nature of South Africa’s apartheid past many people were located in former tribal lands called Bantustans. The Transkei, one of the biggest homelands, is home to some of South Africa’s poorest people, many of whom rely on the marine resources. By 1998 the government sought to acknowledge the previously unrecognised subsistence sector that lived along the South African coastline with the promulgation of the Marine Living Resources Act. The act sought to legalise access rights for fishers and provide opportunities for the development of commercial fisheries. The act and many subsequent policies largely called for co-management as a solution to the management of the subsistence sector. This thesis largely explains the administrative and legislative difficulties in transporting the participatory components of co-management to the ground level. As such co-management has largely remained in rhetoric whilst the government provides a contradictory policy regarding the management of subsistence and small-scale fishers. This thesis attempts to provide qualitative ethnographic research of the East Coast Rock Lobster fishery located in a small fishing village in the Transkei. The fishery falls somewhere on the spectrum between the small-scale and subsistence sector as there are a basket of high and low value resources being harvested. It will be argued that in order to economically and socially develop the fishery the social capital and social networks of the community and various stakeholders needs to be analysed in order to effectively create a co-management network that can create a successful collective management of natural resources thereby sustaining these communities in the future.

The intertidal distributions, densities and biomasses of R. stephensoni, P. sykion and N. grammatus were examined at six sites from Port Elizabeth to East London in the eastern Cape. At all sites the three species showed similar overlapping zonations with R. stephensoni and P. sykion reaching their highest maximum mean densities and biomasses (drained wet weight) in the lower mid-shore region (401m² and 684g/m², 181m² and 269g/m², respectively at Port Elizabeth), whilst N. grammatus in the low-shore region (61m² and 72g/m², at Port Elizabeth). The highest densities and biomasses of all three species were recorded on boulder shores that had minimal sand inundation. Seasonality of reproduction of R. stephensoni, P. sykion and N. grammatus was compared at Port Elizabeth, using gonad index values, gonadal tubule diameters, egg diameters and spermatozoon content in tubules from January 1992 until August 1993. All three species are dioecious and did not deviate from a 1: 1 sex ratio. Sizes at first sexual maturity were 2.5-2.9 cm³ for R. stephensoni and P. sykion, and 3.0-3.9cm³ for N. grammatus. The gonads of R. stephensoni and P. sykion consist of a bunch of unbranched tubules of equal diameter, with males having more tubules of a smaller diameter than females. By contrast, the gonad of N. grammatus consists of two tufts of multiple branched tubules. All three species followed annual reproductive cycles, and in R. stephensoni and P. sykion gametogenesis occurred from March 1992 until August/September 1992, and maturity was maintained until the main spawning event in January 1993. By contrast, in N. grammatus gametogenesis occurred from July 1992 until September 1992, and maturity was maintained until the main spawning event in December 1992/January 1993. Unlike R. stephensoni and P. sykion the reproductive cycle of N. grammatus was more pronounced, in that the gonad regressed after spawning. Aspects of the feeding biology of R. stephensoni, P. sykion, A. spyridophora, R.ffrauenfeldi and N. grammatus were compared, using the gross buccal tentacle morphology, type and size range of ingested food particles, and gut lengths. Scanning electron microscopy revealed that the buccal tentacles of R. stephensoni, P. sykion and A. spyridophora could be classified as dendritic, branching numerous times with the tips terminating in numerous nodes covered with discs of papillate projections. The buccal tentacle structure of R. f frauenfeldi deviated from the typical dendrochirote dendritic form. The tentacles are stout with few branches which terminate in large bulbous nodes lacking discs of papillate projections. Neostichopus grammatus possesses buccal tentacles that could be classified as peltate, terminating in large nodes which also lacked discs of papillate projections. Roweia stephensoni, P. sykion and A. spyridophora are suspension-feeders, ingesting food particles mostly <53μm in size. Roweia f frauenfeldi was classed as a "heavy" suspension-feeder, ingesting food particles mostly between 250μm-1.18μm, while N. grammatus is a deposit-feeder, ingesting benthic sediments mostly between 106-500μm. The gut lengths of the dendrochirote holothurians were found to be significantly longer than that of the aspidochirote, and may be attributed to the nature of the food ingested.

Full textAbstract:
Rainforest Restoration Manual for South-Eastern Australia is the definitive guide to the recovery and restoration of Subtropical, Warm Temperate, Cool Temperate, Gallery, Dry, Dry Gully and Littoral Rainforests from south-eastern Queensland to
Tasmania. All of these rainforest types were inherently rare prior to settlement, and today with depletion, feral animals, weeds and climate change, all are threatened – with many listed under state and federal legislation.
The manual presents detailed restoration methods in 10 easy-to-follow steps, documenting the research and trials undertaken during rainforest restoration over more than two decades. These experiments and their results will empower readers to uncover answers to many of the problems they could encounter. The manual is supported by a CD that provides important background information, with 32 appendices, a propagation manual for the region's 735 rainforest plants, an illustrated glossary and resources for teachers. Species lists and specific planting guides are provided for the 57 rainforest floristic communities that occur from the
coast to the mountains between Durras Mountain in New South Wales and the Otways in Victoria.
Extensively illustrated with colour photographs, this book will empower you or your group to be able to restore, manage, protect and conserve the magnificent rainforests that are in your care. The general principles and techniques described will meet the needs of students and teachers, novices, experienced practitioners, community groups and agencies alike.

AbstractAs the Green Climate Fund continues to make concerted efforts to leverage funding for resource-constrained communities in the global south under the aegis of increasing climate change impacts in sub-Saharan Africa, there is urgent and compelling need for tools that assist organizations to track the effectiveness of adaptation interventions in reducing vulnerability. This chapter offers a cost-effective methodology to track adaptation by using a case-study-based identification of communities with diminishing coping capacities in Raymond Mhlaba Local Municipality in the Eastern Cape Province of South Africa. Multistep geostatistical techniques were utilized in the ArcGIS 10.5 software environment to rank and spatialize changes in adaptation by using demographic census data for the years 2001 and 2011. Results of the analysis revealed that 12 communities had declining or static adaptive capacities between 2001 and 2011, while 10 communities had long-term decrease in adaptive capacities from 2001 to 2011 from a sampling universe of 134 communities. These findings are important because they demonstrate that the methodology can be effectively used to provide actionable information on the prevalence of low adaptation capacities at appropriate temporal and spatial scales, in order to guide the allocation of limited resources to the most deserving communities.

Abstract This volume contributes to research on migration from Latvia, a country in Central Eastern Europe (CEE), following the fall of the Iron Curtain in 1991. The experience of independent Latvia with borders opening up to the world and more specifically to the West has turned out to be both a rewarding and wounding experience for communities in the country. On the rewarding side, individuals have gained liberty – an ability to travel the world freely, to see and live in the countries which were beyond the closed doors of the Soviet Union just some decades ago. This freedom, however, has also brought the sense of cost to the society – people are going abroad as if dissolving into other worlds, away from their small homeland. The context of decreasing birth rates and ageing in the country seems to amplify a feeling of loss which is supported by hard evidence. Research shows a worrying 17% decline in Latvia’s population between 2000 and 2013. One third of this is due to declining birth rates and two-thirds is caused by emigration (Hazans 2016). This situation has turned out to be hurtful experience for communities in Latvia causing a heightened sense of grief especially during the Great Recession which shook the country at the end of the first decade of the twenty-first century. By 2013 the feeling of crises even larger than the economic downturn came to a head in Latvian society, pushing the government for the first time in the history of independent Latvia to recognise the migration of the country’s nationals and to acknowledge diaspora politics as an important item on the national policy agenda.

The Republic of South Africa, known as South Africa, occupies the most southern tip of Africa with a coastline stretching from the border of Namibia on the Atlantic Ocean (south-west coast) of Africa, down to the tip of Africa and then north along the south-east coast to the border of Mozambique on the Indian Ocean. South Africa is bordered by Namibia, Botswana, Zimbabwe, Eswatini (formerly Swaziland), and Mozambique and surrounds the small landlocked Kingdom of Lesotho in the east-central region of South Africa. The total area of South Africa is approximately 1.22 million square kilometres (km), with a population of an estimated 58.78 million (2019). The country is divided into nine provinces, Western Cape, Eastern Cape, Northern Cape, Free State, Kwa-Zulu Natal, Northwest, Gauteng, Mpumalanga, and Limpopo. Gauteng Province is the most densely populated province with approximately 809.6 people per square kilometre, Kwa-Zulu Natal being the second most densely populated at 120.7 people per square kilometre, with Western and Eastern Cape following substantially behind at 59.1 and 51.1 people per kilometres respectively. There are three capitals in South Africa: Pretoria in the Gauteng province (administrative), Cape Town in the Western Cape (Legislative), and Bloemfontein in the Free State (Judicial). The

Full textAbstract:
Festivals are recurrent celebrations and often with ritual events and meanings. Festivals reveal something of the identity, values and world views of the community or ethnic group that celebrates them (Szabó, 2015). Festive occasions involve local residents and visitors. In Ghana, there are several festivals celebrated by different ethnic groups. For example the people of Accra, the capital of Ghana, celebrate the Homowo festival, which is a festival that literally ‘hoots at hunger’. The festival was initiated following a bumper harvest after years of famine and hunger. The people of Akropong, Akwapim in the eastern region of Ghana celebrate the Odwira festival. It is a festival that enables the people to purify ancestral stools 2 and spiritually cleanse the towns and villages in and around Akropong. In the same way the people of Cape Coast also celebrate the Fetu Afahye festival, which is a multi-purpose festival that marks cleansing of the people of Cape Coast from a plague in pre-colonial times. The festival also celebrates an abundant harvest of fish from the sea and offers the opportunity for the people in the area to thank the seventy-seven deities of the Cape Coast for their protection over the years (Opoku 1970). The Ewe people of Anlo, in the Volta Region of Ghana, celebrate a festival called Hogbetsotso. It is a migration festival that tells the story of the escape of a group of Ewes from one of their tyrannical rulers, King Agokoli. The Dagomba people of the Northern Region celebrate the Bugum or fire festival. Local traditions provide two explanations for the festival. The first credits the origin of the festival to the Prophet Noah whose Ark docked on Mount Ararat. Local historians claim that after the floods the occupants of the Ark came out with torches to find their way out and around. The second version indicates that at a point in the history of the Dagomba people a king lost his son. The king assembled his warriors who composed a search party. They finally found the son in the night sleeping under a tree. Because they managed to find him using torches made from grass, the king decreed that every year the event should be celebrated with torches made from grass.

Full textAbstract:
The Denali-Yukon domain occupies a broad arc that, in general, follows the path of the Denali Fault along the Alaska Range and southwestward into the Yukon Territory. An ophiolite in the northwestern corner of British Columbia that is northeast of the projected Denali fault is included in this locality. A projection of the Denali fault system southwestward from the Alaska Range passes through the southwestern part of the Ahklun Mountains physiographic province, as the province was defined by Wahrhaftig (1965), to Kuskokwim Bay between the mouth of the Kuskowim River and Cape Newenham. Three mafic–ultramafic complexes on the southwestern edge of the Ahklun Mountains province are included in this domain. Glaciers covered this entire domain during the Pleistocene, and mountain glaciers and ice caps are still present at the higher elevations. Permafrost is currently discontinuous. The highest mountain in North America (Mt. McKinley, 6194 m) is in the Alaska Range, but the ultramafic rocks are all at much lower elevations. The climate is very cold throughout the domain, with severe winters and short summers. The mean annual precipitation ranges from 45 to150 cm in the Ahklun Mountains, from 30 to 60 cm in the Alaska Range, and from 30 to 75 cm, or more, in the Atlin area of northwestern British Columbia, which is in the rain shadow of the Coast Mountains. The greatest precipitation is during summers, from June or July to September or October. The frostfree period is on the order of 60–90 days, or shorter, but it may be longer in some of the Atlin area of British Columbia. Localities 9-1 through 9-3 are from Cape Newenham northeastward in the Ahklun Mountains. The ultramafic rocks in the Cape Newenham area were accreted to North America by north directed thrust faults during the Late Triassic and Middle Jurassic time. Localities 9-4 through 9-7 are in the Alaska Range. Locality 9-8 is along a projection of the Denali fault to the eastern edge of the Coast Ranges in British Columbia.

As a scientist, the Long-Term Ecological Research (LTER) program has been on my mind for more than three decades. As an educator, I have served in the classroom for 41 years. The merger of the physical and the ecological sciences was at the core of my teaching philosophy. As a science communicator, I informed the general public on issues of climate and climate change. As a collaborator, I found that understanding strengths and weaknesses in collaborative partnerships best ensures success. As a science leader, I served at the National Science Foundation (NSF) as the Director of the Division of Environmental Biology (DEB), established the Schoolyard LTER Program, and launched the National Ecological Observatory Network (NEON). My disciplinary background includes formal graduate education at the University of Wisconsin in meteorology, climatology, and paleoclimatology, as well as in oceanography and biology (mycology, botany, zoology, and genecology). As a postdoctoral fellow, my scientific identity was on track to culminate as a paleoclimatologist. As an assistant and associate professor, my identity morphed to include coastal geomorphology (Hayden et al. 1995). Finally, my experiences in the LTER program have vectored my career toward the interactions of climate and vegetation (Hayden 1998). My affiliation is with the Virginia Coast Reserve (VCR) site in the LTER program (1986–2014). As one of the founding principal investigators of the VCR site, I have served in subsequent renewals as its principal or co-principal investigator. Our site-based research plan focused on the Virginia Coast Reserve on Virginia’s eastern shore with a focus on the dynamics of the chain of 14 barrier islands, bounded by the entrance to the Chesapeake Bay to the south and Assateague Barrier Island to the north. This peninsula is 100 km in length by 20 km in width. Only the islands fronting the Mississippi delta are more dynamic in both the temporal and spatial domains. Prior to joining the LTER program, my research was hemispheric to regional in scope, and it focused on the environmental dynamics of the Atlantic Coast from Florida to Cape Cod at 50-m intervals (Fenster and Hayden 2007).

The American continent extends over 12,000 kilometres from Alaska to Cape Horn, and encompasses an enormous variety of environments from arctic to tropical. For the purposes of this discussion, such a huge variety has to be simplified into a few major geographical units within the three regions of North, Central, and South America (Fig. 7.1). Large tracts of Alaska and modern Canada north of the 58th parallel consist of tundra, which extends further south down the eastern coast of Labrador. To the south, boreal coniferous forests stretch eastwards from Lake Winnipeg and the Red River past the Great Lakes to the Atlantic, and westwards from the slopes of the Rockies to the Pacific. The vast prairies in between extend southwards through the central United States between the Mississippi valley and the Rockies, becoming less forested and more open as aridity increases further south. South of the Great Lakes the Appalachian mountains dominate the eastern United States, making a temperate landscape of parallel ranges and fertile valleys, with sub-tropical environments developing in the south-east. The two together are commonly referred to as the ‘eastern Woodlands’ in the archaeological literature. On the Pacific side are more mountain ranges such as the Sierra Nevada, separated from the Rockies by arid basins including the infamous Death Valley. These drylands extend southwards into the northern part of Central America, to what is now northern Mexico, a region of pronounced winter and summer seasonality in temperature, with dryland geology and geomorphology and xerophytic vegetation. The highlands of Central America, from Mexico to Nicaragua, are cool tropical environments with mixed deciduous and coniferous forests. The latter develop into oak-laurel-myrtle rainforest further south in Costa Rica and Panama. The lowlands on either side sustain a variety of tropical vegetation adapted to high temperatures and frost-free climates, including rainforest, deciduous woodland, savannah, and scrub. South America can be divided into a number of major environmental zones (Pearsall, 1992). The first is the Pacific littoral, which changes dramatically from tropical forest in Colombia and Ecuador to desert from northern Peru to central Chile. This coastal plain is transected by rivers flowing from the Andes, and in places patches of seasonal vegetation (lomas) are able to survive in rainless desert sustained by sea fog.

Rural development and poverty alleviation are a priority for development in South Africa. Information and knowledge are key strategic resources for social and economic development, as they empower rural communities with the ability to expand their choices through knowing what works best in their communities. Information Communication Technologies (ICTs) act as tools which enable existing rural development activities. The Siyakhula living lab (SLL) aims to develop and field-test a distributed, multifunctional community communication platform, using localization through innovation, to deploy in marginalized communities in South Africa. The project exists as research collaboration between the Telkom Centres of Excellence at the University of Fort Hare and Rhodes University. Its current pilot operates in the Mbashe municipal area, which is a deep rural area located along the wild coast of the Eastern Cape province of South Africa. The Dwesa-Cweba Nature Reserve acts as a chief asset in the community, which contributes to tourism development. However, the community is currently not actively involved in tourism development; but potential exists in local arts, crafts, and authentic heritage tourism. Therefore, the SLL aspires to empower the community with appropriate communication technology skills to actively support tourism development and other complementary development activities, such as, education. The lessons learned and applied in the project’s current pilot stage identify techniques and approaches that aim to promote the effectiveness and sustainability of the ICT project in a rural context. These approaches and techniques are viewed and described from social-cultural, institutional, economic, and technological perspectives.

Full textAbstract:
This chapter focuses on the films whose plots are set in the period following the break-up of the Soviet Union and in which the Baltic Sea undergoes symbolic transformation from a metaphor of liminal space into a space which links the Nordic peripheries of Europe with neighbours on the opposite shores. Rather than being positioned as small nations facing a large and dangerous neighbour, the small Nordic countries now find themselves among equally small neighbours that have (re)emerged in the northern consciousness after the disintegration of the Eastern Bloc. In these pictures (such as Aki Kaurismäki’s Take Care of Your Scarf, Tatjana), Baltic is an expanse of ambivalence, reflecting both fear of and fascination with the newly opened borders and increasing globalisation. Plots structured on the cognitive binary of centre/periphery are examined as baselines for narratives showing various forms of distant neighbourhood. Here, the Nordic subjects are often ousted from the centre position they previously adopted. Filmic devices serve to compress the space in order to accentuate contiguity rather than distance between the Nordic and the Eastern European coasts of the Baltic.

Full textAbstract:
In this paper, we present a fused flight dynamics and wake interaction modeling framework for arrays (farms) of tethered wind and marine hydrokinetic energy systems. The replacement of conventional towers with tethers necessitates a dynamic model that captures the flight characteristics of each system, whereas the arrangement of the systems in an array necessitates a wake interaction model. The integration of these components is unique to the tethered energy systems literature and is applicable to both airborne wind energy systems and tethered marine hydrokinetic energy systems. In the application case study of this paper, we focus specifically on arrays of ocean current turbines (OCTs), which are intended to operate in the deep waters of the Gulf Stream, adjacent to the eastern coast of the United States. In particular, we evaluate the dynamic performance and resulting projected energy output of an array of tethered OCTs, based on real Gulf Stream resource data from an acoustic Doppler current profiler (ADCP) located adjacent to Cape Hatteras, North Carolina.

To achieve a more robust interpretation of sediment conditions and transport, our study combines the two different interpretation techniques. A side-scan sonar survey was used as a basis for detail sedimentological investigation. Grain-size analyses of grab samples provided sediment transport direction and decoding of sonar data. The new detail lithological map of the underwater shore slope of the northern Sambian peninsula and the Russian part of the Curonian spit in 1:50 000 scale is created. For the first time, the stretched zone of very fine sands is outlined at depths of 25-30 m of the Curonian spit underwater slope. These sands are relicts, and their formation is connected with accumulative processes on the ancient shores of the Baltic Sea. Separate morpho-lithodynamic cells are distinguished on the submarine slope of the northern Sambian peninsula coast up to a depth of 20 m. The cape areas of the Sambian peninsula serve as cell boundaries where a divergence of sediment trend and seabed erosion are observed. The convergence of sediment transport directions is confined to the bight’s central parts. Fine and very fine-grained sand accumulation prevails here.

Aim/Purpose: This paper seeks to show how University of South Africa (UNISA) is using technology to connect lecturers, tutors and students of [UNISA] in an underdeveloped region in South Africa (SA) to reduce cost and time of travelling to access information, tutorials and help [available] in designated centers, hence making quality and higher education more accessible and less costly. Background: This empirical study gives evidence to back the effectiveness, helpfulness and cost reduction of using technology as a medium of making quality and higher education accessible to under developed regions. Methodology Quantitative and purposeful sampling was deemed appropriate for the study, whereby 200 questionnaires was developed and specifically distributed to UNISA students from former Ciskei towns at East London Tutorial Center. Contribution: The paper is about the usage of mobile technology for knowledge creation and dissemination, instruction and learning, The data generated and presented add to the knowledge base about underdeveloped countries. This data and the conclusions reached based the analysis could be of interest to researchers, university administrators, politicians, planners and policy makers in underdeveloped countries. Findings: Evaluation of the overall effectiveness, helpfulness and cost reduction of e-tutorials show a slight advantage over the face-face tutorials. Recommendations for Practitioners: In the quest for ways and means of making quality and higher education accessible to underdeveloped regions, no matter which medium is chosen, the periodic measurement of success in terms of effectiveness, helpfulness, and cost implication in relation to the learner cannot be over looked. Recommendation for Researchers: More work needs to be done to check the effectiveness of technology as an efficient medium to provide access to quality and higher education to underdeveloped regional economies. Impact on Society The results could have significant implications for raising the level of education and advancing employment equity by improving the delivery and accessibility to quality and higher education to underdeveloped regional economies. Future Research: The analysis of cost efficiency and effectiveness done in this work is just representative of one point of view: the student one of accessibility and cost. There is, however, need in future work to research the implications for the institutions of higher education (in terms teaching design, curriculum design, knowledge of individual learning types, need for change in and rate of change in knowledge view, learning philosophies), individual stakeholders, and the competitive repositioning of society.

Assessment of renewable energy resources, such as surface solar radiation and wind current has great relevance in the development of local and regional energy policies. This paper examines the variability and availability of these resources as a function of possible climate changes for the Caribbean region. Global climate changes have been reported in the last decades, causing changes in the atmospheric dynamics which affects the net solar radiation balance at the surface and the wind strength and direction. For this investigation, the future climate changes for the Caribbean are predicted using the Parallel Climate Model (PCM) and it is coupled with the Regional Atmospheric Modeling System (RAMS) to simulate the solar and wind energy spatial patterns changes for the specific case of the island of Puerto Rico. Numerical results from PCM indicate that the Caribbean basin from 2041 to 2055 will experience a slight decrease in the net surface solar radiation (with respect to the years 1996–2010), which is more pronounced in the western Caribbean Sea. Results also indicate that the easterly winds have a tendency to increase in its magnitude, especially from the years 2070 to 2098. The regional model showed that important areas to collect solar energy are located in the eastern side of Puerto Rico, while the more intense wind speed is placed around the coast. A future climate change is expected in the Caribbean that will result in higher energy demands, but both renewable energy sources will have enough intensity to be used in the future as an alternative energy sources to mitigate future climate changes.

Silver salmon is usually cultured around the eastern coast of Tohoku Region in Japan. The smolt of silver salmon begins to be cultured in a cage from November. Currently, the aquaculture of silver salmon is terminated until the end of July due to high water temperature since silver salmon will die in a few days if the diurnal minimum water temperature becomes 21 or 22°C. Live salmon cannot be obtained around August because wild salmon is captured from September or October. In the present study, a submergible cage using flexible tubes is proposed to farm silver salmon in deeper and cooler waters in August. The cage was submerged and floated up by ejecting air from and injecting air into the flexible tubes, respectively. The flexible tubes were inserted into the polyethylene pipes. First, water tank test using the 1/3.64 scaled model was carried out in the Ocean Engineering Basin, Institute of Industrial Science, The University of Tokyo. The cage was submerged or floated up, changing the methods of air ejection or injection. The cage was submerged and floated up faster in case of two vents to increase the rate of air flow than in case of only one vent on flexible tubes. The submersion was also faster if the length of an injection tube between the vents and air compressor was shortened to reduce the pressure loss. However, the maximum inclination angle of the cage was determined by the diameter of the cage and the submerged depth, not depending on the methods of air injection or ejection. Similar results were observed in the field test. Consequently, silver salmon could be farmed in deeper and cooler waters until the middle of August. The inclination of the cage was not the problem for silver salmon, while it may have unfavorable effects on the other species through the deformation of netting. Hence, the methods to reduce the inclination of the cage in submerging or floating up operation should be considered and validated in field test in the future.

Full textAbstract:
Digital and representation: the second line and the forgotten castle of FiumedinisiThe Belvedere Castle of Fiumedinisi (ME) belongs to that historical heritage of Sicily characterized by abandoned and forgotten military architecture. Along the Ionian coast the defensive problem has been particularly felt over time, due to the proximity of the Turkish coast, the Middle East and the African one. The first defensive line was the coastal one, defined by principals placed on the sea in a strategic position for direct control of the coast. They were part of this group: the Maniace castle of Syracuse, that of Augusta, of Brucoli, of Catania, of Acicastello, the Tocco of Acireale, Schisò in the territory of Giardini, Capo Sant'Alessio, the Saracen Tower of Roccalumera, Capo Grosso in Ali , San Salvatore in Messina. Along the eastern side of the Peloritani mountains from Calatabiano to Messina, the island's defensive strategy also included a second line of fortifications, which controlled a more distant horizon from their position. These include the castle of Calatabiano, Taormina, Castelmola, Forza d’Agrò, Savoca, Fiumedinisi, Scaletta Zanclea, Santo Stefano di Briga, Matagrifone. Among them, the Belvedere castle of Fiumedinisi, at a critical distance from the village, so as to be in a state of neglect, among those listed is that which is in the worst conditions. In stark contrast to the dignity and history of the site and territory of Fiumedinisi, dating back to the Greek period. In this work we propose the survey of the castle with digital, photogrammetric technologies, Structure From Motion (SFM) and dense matching, to arrive at a 3D documentation and graphic drawings, considering that to date there are no significant scientific surveys and representations of this abandoned fortress.

In The International Workshop on Information, Computation, and Control Systems for Distributed Environments. Crossref, 2020. http://dx.doi.org/10.47350/iccs-de.2020.12.
Full textAbstract:
The article presents a universal diesel generator model based on the processing of the engine speed characteristic. Processing uses linear interpolation with a fixed discrete step. An autonomous photovoltaic system arbitrarily located in Eastern Siberia is used as a case study. Solar radiation modelling was based on multi-year meteorological data sets using the tandem of Iqbal-Kasten/Czeplak models. The photovoltaic system under investigation consists of two 400 kW diesel generators (totalling 800 kW) and one 375 kW solar power plant. In calculating the operating modes, the diesel power plant’s minimum limit load factor was taken into consideration. The resulting values of the diesel generator’s operating modes show the following patterns. As an example, the lesser the diesel generator’s load, the lesser engine speed and the higher specific fuel consumption. The suggested model can be used in comprehensive energy research, specifically in areas such as optimal equipment configuration, operational reliability and sustainability as well as cost-efficiency.

"Comparative Study of Managed Pressure Drilling Application in Deepwater Gas Wells - Case Study from Offshore Eastern Mediterranean of Egypt."

Full textAbstract:
Abstract Although devised in 2003, managed pressure drilling (MPD) has gained widespread popularity in recent years to precisely control the annular pressure profile throughout the wellbore. Due to the relatively high cost and complexity of implementing MPD, some operators still face a challenge deciding whether or not to MPD the well. In the offshore Mediterranean of Egypt, severe to catastrophic mud losses are encountered while conventionally drilling deepwater wells through cavernous fractured carbonate gas reservoirs with a narrow pore pressure-fracture gradient (PP-FG) window, leading to the risk of not reaching the planned target depth (TD). Furthermore, treating such losses was associated with long non-productive time (NPT), massive volume consumption of cement, and lost-circulation materials (LCM), in addition to well control situations encountered several times due to loss of hydrostatic head during severe losses. Accordingly, the operator decided to abandon the conventional drilling method and implement MPD technology to drill these problematic formations. In this paper, the application of MPD is to be examined versus the conventional drilling in terms of well control events, NPT, rate of penetration (ROP), mud losses per drilled meter, LCM volume pumped, and drilling operations optimization. According to the comparative study, MPD application showed a drastic improvement in all drilling performance aspects over the conventional drilling where the mud losses per drilled meter reduced from 19.6 m3/m to 3.7m3/m (123.2 bbl/m to 23.4 bbl/m). In addition to that, a 35% reduction of NPT and also a 35% reduction of LCM pumped, and 67.2 % reduction by volume of cement pumped to cure the mud losses. Moreover, the average mechanical rate of penetration increased by 37.4%. MPD was also credited with eliminating the need for an additional contingent 7" liner which was conventionally used to isolate the thief zone. The MPD ability to precisely control bottom hole pressure during drilling with the integration of MPD early kick detection system enables the rapid response in case of mud loss or kick, eliminating kick-loss cycles, well control events, and drilling flat time to change mud density. This paper provides an advanced and in-depth study for deep-water drilling problems of a natural gas field in the East Mediterranean and presents a comprehensive analysis of the MPD application with a drilling performance assessment (average ROP, mud losses, LCM and cement volumes, well control events) emphasizing how MPD can offer a practical solution for future drilling of challenging deepwater gas wells.

Full textAbstract:
The Government of Indonesia plans to build 9 gas power plants in South Kalimantan, South Sulawesi and Southeast Nusa Tenggara with a total power capacity of 780 MW with an estimated actual gas demand of 46.56 MMSCFD which are planned to be supplied by the Bontang terminal, DS-LNG, Masela LNG, and Tangguh LNG. LNG-C logistics optimization is needed to get the best transportation scenario regarding the eastern region which consists of scattered islands and inadequate infrastructure. This study analyzes and evaluates the best-case scenarios by comparing the time and cost variables. The process of planning the supply chain starts from determining the upstream-downstream distribution scheme and then calculates the shipping distance which results in the determination of the quantity, capacity and shipping of the LNG-C. Based on the analysis and calculation of the logistics, it is concluded that there are 3 divisions of clusters of Kalimantan-Sulawesi, NTT and NTB having estimated needs in a row of 18.06, 18.8, and 9.7 MMSCFD with the Milk-Run transportation method. Logistics optimization results show that scenario 1 has an efficiency value of 87% with an LNG-C transport capacity of 0.35 MMSCF, a roundtrip cruise time of 8.6 days and the number of shipments is 36 / year. The detailed analysis of costs in scenario A is 1-2 USD / MMBTU for the milk and run transportation method, 1.49-1.73 USD / MBTU for LNG-C transport costs, and regasification costs which are 1.0-3.7 USD / MMBTU. Based on the above results it can be calculated that the price of gas in the first year of implementation was 13.4 USD / MMBTU, so the total value below this supply chain was Rp.8,812,876,800.00. Therefore, this idea was created as a solution for the initial steps for the utilization of the domestic natural gas distribution
