At present, China is establishing eco-compensation mechanism on the basis of key ecological function zones and ecological factors, but trans-provincial eco-compensation mechanism (especially in river basin) is making slow progress due to its complicated stakeholders involvement. The promulgation of relevant papers, such as Planning on National Main Functional Zones and National Key Ecological Function Zones, provide important basis and new thoughts for implementing eco-compensation mechanism in China. In this paper, we take trans-provincial key ecological function zone as breakthrough point to study trans-provincial river basin eco-compensation mechanism, and take the source area of Dongjiang River in Jiangxi province and Guangdong province as an example to put forward some ideas for trans-provincial river basin eco-compensation mechanism designing based on the key ecological function zones. Taking the study of key ecological function zone as the platform, we propose a framework of river basin eco-compensation plan, which includes particular design in the following aspects: the funding needs, funding sources, financial operation mechanism, monitoring and evaluation, organizational management and compensation security system. Designing River basin eco-compensation mechanism in source areas while based on key ecological function zone, which will increase the scientific nature and rationality of policy making, is more in line with ideas and concepts of payment for ecosystem services (PES) and it will effectively promote scientific and rational development and implementation of river basin eco-compensation. However there are still many inevitable problems in the following aspects: river basin eco-compensation monitoring and evaluation, management of river basin eco-compensation and measures to ensure the long-term effect of river basin eco-compensation policy. With the in-depth understanding of eco-compensation study and practice in China, these problems should be constantly improved and Chinas eco-compensation mechanism will become increasingly complete and rigorous in the future.

Van Don district has many favorable conditions in terms of geographical location, economic and political position, and diversity in natural resources for developing marine economic zone. The strength of the district is to develop eco-tourism, conservation of valuable marine ecosystems as well as exploitation of minerals and construction materials. At the present, Van Don is facing negative impacts from urbanization and economic development, environmental degradation, and reduction of biodiversity. Therefore, the purpose of this study aims to determine the zoning criteria and application for the functional zoning for sustainable use of environment and natural resources in Van Don island district. Based on the zoning criteria and natural and socio-economic characteristics, Van Don island district can be divided into two main environmental and natural resources function zones, consisting of Cai Bau island zone (with 3 sub-zones) and Van Hai zone (with 4 sub-zones). Each sub-region has its own unique characteristics that are scientific foundations for orienting sustainable development.

Acne (acne vulgaris) is a skin disease caused by infection or inflammation of the pilosebaceous unit. Staphylococcus aureus and Prapionibacterium acnes was the main actor in the infection. Eco-enzyme that is made from pineapple peel has been stated that have inhibitory activity against gram-positive and negative bacteria, also applied as home industry soap. This study objective as scientific support that Eco-enzyme phytochemical compounds had the antibacterial activity to the acne bacteria. Eco-enzyme was composed of pineapple peel, brown sugar, and water with the ratio of 3:1:10 for 3 months fermentation time. Eco-enzyme was screened of its phytochemical compound and antibacterial activity against S.aureus and P.acnes by dilution with various concentrations (1.5625%, 3, 125%, 6.25%, 12.5%, 25%, and 50% v/v) and various control. The minimum inhibition concentration (MIC) was then tested by diffusion method to determine the inhibition zone with 3 replication using the higher concentration (50%, 75%, 100% v/v). The result showed that eco-enzyme has a clear yellow colour, contains tannin and saponin, MIC of S.aureus and P.acnes bacteria is 50%. The dilution test of eco-enzyme gives the most effective concentration to inhibit S.aureus at eco-enzyme 100% (v/v), contrasted to P. acnes which didn’t show the best inhibition concentration.

As the wetlands has decreased and degenerated badly due to human’s excessive use, it becomes to be a hotspot in international academe’s forefield to resume and rebuild wetlands. Simply opposing protection to using can effectively ease up the stress of wetland’s degradation in a short term, but is disadvantageous to wetland’s sustainable development. This article takes Tianjin Qilihai wetland as example, aiming at its existing problems, sums up two kinds of infection genes – exterior representation and interior motivation, and intensively analyzes the sticking point from three aspects – economic, acknowledgement and mechanism. It suggests that basing on the idea of accretion and co-prosperity, we can divide wetland area into three zone – core zone, buffer zone and experimental zone, and then let the interior dispersive inhabitants and production activities move out to the intensively constructed eco-town. Thus we can make scientific use of wetland’s economical value and promote circumjacent industries’ transformation. Moreover, by the recycling use of water on a model of source separation combined with wetland classification, the quantity of regenerated water would reach 18.25 million cubic meters. By the Low Impact Development (LID) strategies in the control and use of rainfall and flood, the quantity of rainwater for use would reach 8.62 million cubic meters per year. In this way, the wetlands’ ecological conservation would obtain regurgitation-feeding, the construction of eco-town would be organically combined with protection and using of wetlands, and an effective system of wetlands’ sustainable development and using would be established.

To combat global warming, the development of eco-friendly ultra-high performance concrete (UHPC) has become one of the current research hotspots. Understanding the relationship between composition and performance of eco-friendly UHPC from a meso-mechanical point will be of great significance in proposing a more scientific and effective mix design theory. In this paper, the 3D discrete element model (DEM) of an eco-friendly UHPC matrix was constructed. The mechanism of the effect of the interface transition zone (ITZ) properties on the tensile behavior of an eco-friendly UHPC matrix was studied. The relationship between composition, ITZ property, and tensile behavior of eco-friendly UHPC matrix was analyzed. The results show that ITZ strength influences the tensile strength and cracking behavior of eco-friendly UHPC matrix. The effect of ITZ on the tensile properties of eco-friendly UHPC matrix is more significant than that of normal concrete. The tensile strength of UHPC will be increased by 48% when the ITZ property is changed from normal condition to perfect. Improving the reactivity of the binder system of UHPC will improve the performance of ITZ. The cement content in UHPC was reduced from 80% to 35%, and the σITZ/σPaste was reduced from 0.7 to 0.32. Both nanomaterials and chemical activators can promote the hydration reaction of the binder material, which in turn leads to better ITZ strength and tensile properties for an eco-friendly UHPC matrix.

The Arctic zone is a strategically important region for the sustainable development of the Russian Federation and the Union State. At the same time, an absolutely large part of the population and economic activity in the Arctic is concentrated in the coastal zone. For the effective decision-making process support on the sustainable development of Arctic regions, it is necessary to develop scientific justifications for the implementation of Arctic strategies. As a such tool an information and analytical system can be used in the form of a model of strategic spatial planning of Arctic coastal eco-socioeconomic systems based on an indicator approach. The current state and trends of socio-economic development of the Arctic coastal regions of Russia are analyzed as an approbation of this model.

Abstract. The Balkan Lake Ohrid is the oldest and most diverse freshwater lacustrine system in Europe. However, it remains unclear whether species community composition, as well as the diversification of its endemic taxa, is mainly driven by dispersal limitation, environmental filtering, or species interaction. This calls for a holistic perspective involving both evolutionary processes and ecological dynamics, as provided by the unifying framework of the “metacommunity speciation model”.The current study used the species-rich model taxon Gastropoda to assess how extant communities in Lake Ohrid are structured by performing process-based metacommunity analyses. Specifically, the study aimed (1) to identifying the relative importance of the three community assembly processes and (2) to test whether the importance of these individual processes changes gradually with lake depth or discontinuously with eco-zone shifts.Based on automated eco-zone detection and process-specific simulation steps, we demonstrated that dispersal limitation had the strongest influence on gastropod community composition. However, it was not the exclusive assembly process, but acted together with the other two processes – environmental filtering and species interaction. The relative importance of the community assembly processes varied both with lake depth and eco-zones, though the processes were better predicted by the latter.This suggests that environmental characteristics have a pronounced effect on shaping gastropod communities via assembly processes. Moreover, the study corroborated the high importance of dispersal limitation for both maintaining species richness in Lake Ohrid (through its impact on community composition) and generating endemic biodiversity (via its influence on diversification processes). However, according to the metacommunity speciation model, the inferred importance of environmental filtering and biotic interaction also suggests a small but significant influence of ecological speciation. These findings contribute to the main goal of the Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO) deep drilling initiative – inferring the drivers of biotic evolution – and might provide an integrative perspective on biological and limnological dynamics in ancient Lake Ohrid.

Eco Scientific Zone is an area that exhibits an economically, Scientifically and sustainably prosperous habitat for living. In our present world, everything that is around us is an technical invention of some brilliant minds. This web of technical jargon has affected not only our lives but our environment too. By rapidly increasing industries and indiscriminate cutting of trees we already crossed our limits to get back human friendly environment. We are creating new technologies everyday, without considering its impact on our nature. To rectify this problem, I have proposed a Novel technique to establish Eco Scientific Zone via IOT based Hybrid Intelligent Transportation and Communication System. The proposed method has a multidimensional aspects, where each dimension solves the plethora of problems that we face in our present world. With the help of an Hybrid Intelligent Transport and Communication System architecture with IOT devices, we can not only transfer data for long distances but can link various IOT devices that can perform multiple tasks at a single time.

In the past 50 years, human activities and climatic variability have caused major environmental changes in the semi-arid Sahelian zone and desertification/degradation of arable lands is of major concern for livelihoods and food security. In the wake of the Sahel droughts in the early 1970s and 1980s, the UN focused on the problem of desertification by organizing the UN Conference on Desertification (UNCOD) in Nairobi in 1976. This fuelled a significant increase in the often alarmist popular accounts of desertification as well as scientific efforts in providing an understanding of the mechanisms involved. The global interest in the subject led to the nomination of desertification as focal point for one of three international environmental conventions: the UN Convention to Combat Desertification (UNCCD), emerging from the Rio conference in 1992. This implied that substantial efforts were made to quantify the extent of desertification and to understand its causes. Desertification is a complex and multi-faceted phenomenon aggravating poverty that can be seen as both a cause and a consequence of land resource depletion. As reflected in its definition adopted by the UNCCD, desertification is “land degradation in arid, semi-arid[,] and dry sub-humid areas resulting from various factors, including climate variation and human activities” (UN, 1992). While desertification was seen as a phenomenon of relevance to drylands globally, the Sahel-Sudan region remained a region of specific interest and a significant amount of scientific efforts have been invested to provide an empirically supported understanding of both climatic and anthropogenic factors involved. Despite decades of intensive research on human–environmental systems in the Sahel, there is no overall consensus about the severity of desertification and the scientific literature is characterized by a range of conflicting observations and interpretations of the environmental conditions in the region. Earth Observation (EO) studies generally show a positive trend in rainfall and vegetation greenness over the last decades for the majority of the Sahel and this has been interpreted as an increase in biomass and contradicts narratives of a vicious cycle of widespread degradation caused by human overuse and climate change. Even though an increase in vegetation greenness, as observed from EO data, can be confirmed by ground observations, long-term assessments of biodiversity at finer spatial scales highlight a negative trend in species diversity in several studies and overall it remains unclear if the observed positive trends provide an environmental improvement with positive effects on people’s livelihood.

The last decade has been characterized by an increased frequency of climatic anomalies and their amplitude. These anomalies affect the productivity of crops and orchards, which is directly dependent on agro-meteorological conditions. The registered tendencies to change the hydrothermal conditions in the different regions of the country sometimes are a risk factor for their productivity, especially in the initial phenological stages of the development of the fruit trees. Bud dormancy on the fruit trees from the temperate zones is a phase of development that occurs annually and enables trees to survive cold winters. To estimate the chill requirements of orchards, besides temperature data, three chronological dates must be defined: the chill accumulation start date, the deep dormancy breaking date, and the date of eco dormancy end. This study aims to assess the thermal conditions in the initial stages of development of some stone fruit plants grown in Bulgaria. There were analyzed the conditions during the deep dormancy in the orchards and the permanent transition of the average daily temperature above 5�C. Chilling requirements for breaking dormancy were studied for some peach, cherry, and apricot cultivars, located in the regions for industrial producing of these plants. The Utah chilling unit model was used to measure the accumulation of chilling requirements.

Recently, the echosounder systems in the Bulgarian Black Sea shelf have become a standard method of seabed exploration. The paper presents the present-day field activity of bathymetric research, which revised available hydrographic data for the seabed. The study aims to combine and update archival bathymetric data from contemporary multibeam echo-sounding scanning and archive single-beam data. This work presents activity in the second stage of Project �Multidisciplinary study of Burgas Bay � MidBay. (Composition of a detailed digital model of the bottom relief with analysis of modern geomorphological conditions and archaeological forecasting modelling)� with a primary scientific goal to create an overall bathymetric model of the Burgas and Pomorie bays. The studied bay is strongly anthropogenically modified by the port in its southern part. The reconstruction of seafloor topography will allow the detection of substrate varieties and the identification of contemporary geomorphological bedforms and processes. A historical review of hydrographic research and geo base database was created for the seabed of the Bulgarian coastal zone in support of this study with different-year bathymetric surveys. The used data consolidate sonar mosaics, single beam, multibeam bathymetric data and raster satellite images, processed in PDS 2000, SonarWiz, and GIS environment. The coverage and density of the bathymetric data allowed the generation of a seabed digital bathymetric model with a horizontal resolution of 11 m. In addition, a bathymetric map with an interval of 0.5 m was created with high accuracy. Such a high-resolution model is an important advance in the highresolution mapping of the Bulgarian Black Sea coastal zone.

The ability of a computational fluid dynamics (CFD) simulation to reproduce the diesel-like reacting spray ignitionprocess and its corresponding flame structure strongly depends on both the fidelity of the chemical mechanismfor reproducing the oxidation of the fuel and also on how the turbulence-chemistry interaction (TCI) is modeled.Therefore, investigating the performance of different chemical mechanisms not only in perfect stirred reactors butdirectly in the diesel-like spray itself is of great interest in order to evaluate their suitability for being further appliedto CFD engine simulations.This research work focuses on applying a presumed probability density function (PDF) unsteady flamelet combustionmodel to the well-known spray A from the Engine Combustion Network (ECN), using three chemical mechanismswidely accepted by the scientific community as a way to figure out the influence of chemistry in the keycharacteristics of the combustion process in the frame of diesel-like spray simulations. Results confirm that in spiteof providing all of them correct trends for ignition delays (ID) and lift-off lengths (LOL), when comparing with experimentalresults, the structure of the flame presents noticeable differences, especially in the low and intermediatetemperatures and high equivalence ratio regions. Consequently, the selection of the chemical mechanism has animpact on the zones of influence of key species as observed in both spatial coordinates and also in the equivalenceratio-temperature maps. These differences are expected to be relevant considering the implications when couplingpollutant emissions models. The analysis of temperature and oxygen concentration parametric studies evidenceshow the observed differences are consistent and moderately dependent on the ambient conditions.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4746
