However, the economic value of natural landscapes has only been recognized in recent decades, and the resulting large-scale decline and degradation of ecosystems now severely threatens the sustainable provision of their services to society. There is an emerging consensus that natural capital should be incorporated into the current socioeconomic accounting system. Many studies valuated natural resources at local and regional scales, but there are very few empirical studies at a national level. To provide a benchmark for natural landscape management on a national scale, we use the travel cost method(TCM) and the contingent valuation method(CVM) to determine the economic value and the spatial distribution of natural landscapes across China. Our results show that the total economic value of China′s natural landscape was 9.75 × 10^(11) U.S. dollars(USD) in 2012. Of this value, the highest proportion was in the eastern and southwestern regions of China, which accounts for 23.7% and 18.3%, respectively. The provinces of Guangdong, Sichuan, Yunnan, Inner Mongolia, and Heilongjiang were the top five in terms of the largest number of natural landscapes and largest economic values. Together, these five provinces accounted for 32.9% of the total number of natural landscapes and 29.4% of the total economic value in 2012. We believe this study will increase awareness of the value of natural landscapes, and more importantly provide a scientific basis for resolving conflicts between development and resource conservation.展开更多

If so, how large is the source of surplus labor and how long it can be lasting? These questions were hotly debated in the literature abroad. But in Vietnam there is very little or hardly exchanged opinions about the concepts and methods of measurement of surplus labor in general and surplus labor in agriculture in particular. This article refers to the measurement approach of surplus labor in agriculture in Vietnam.展开更多

PES-W is derived from an extension of governance analyses of 163 watershed-based PES (payments for ecosystem services) programs, and from the integrative decision mechanism of IPES (integrated payments for ecosystem services) to generalize the PES approach. PES-W reflects three interrelated perspectives fundamental to the global science of integrated water governance: (1) the ecological and economic perspective to integrate human incentives for integrated water resources governance; (2) the sociological and ecological perspective to form partnerships for meta-monitoring and recta-funding for integrated watershed governance; and (3) the scientific and sociological perspective to develop organizing botmdaries based on technology, lifestyle, entrepreneurship and organizing infrastructure for integrated aquatic ecosystem governance. This study is intended to communicate with the international scientific communities for establishing an advanced, academic, and practical multidisciplinary field of the global science of integrated water governance as a critical condition for sustainable development in human societies.展开更多

This fishery is an important one in the region, but is threatened by increasing over-exploitation which has led to a steady decrease in the production. In addition to over-exploitation problem, a record of tsunami disaster makes this fishery a unique case. This research, based on a set of primary and secondary data was carried out using the Rapfish analytical approach. Primary data were collected using a stratified cluster random sampling technique, where as many as 186 outboard fishing operators were selected. Meanwhile, relevant complementary data were solicited purposively from five employees of Pangandaran Marine and Fisheries Service. Following from the Rapfish approach, it was found through this research that sustainability levels of fisheries in Pangandaran fall into poor category. For all types of fisheries that exist in the region, almost all sustainability dimensions namely ecological, social, technological and ethical dimensions were scored below 50 of the 100 maximum values. This paper concludes with a suggestion, pointing out attributes that should receive government attention in order that the sustainability of the fisheries in the future.展开更多

Entrepreneurship is a global world. It is not possible to think about economic driving force of technological development and scientific research. It materializes knowledge and involvement of people and society. Expansion of business activities is a source of individual country's economic performance. It contributes to the development of people's living standards. In every market economy, it represents an irreplaceable role for small and medium-sized enterprises (SMEs). A strong representation of"micro-enterprises" can be found in the field of personal services. Companies within the course of their existence go through particular stages of their development--from their foundation through the stage of steady development. After this stage, there comes their decline that can develop even into their termination. We indicate this process as a company life cycle. The aim of the submitted project is to map the life cycle of particularly chosen companies providing accommodation and catering services and to find a mutual relation among observed quantities and their stable economic positions in the market. The analysis is based on the data of macro-economic character, the data about development of receipts in the sector, development of inflation, tempo of economic growth, and development of consumer prices. Out of a company, non-financial factors will also be considered. The core of the analysis is the stage of sustainable stability of the assessed companies. The point of the findings is revelation of the causes of risks of possible transition into the stage of termination due to the decline of services volume, decline of profitability, and long-lasting payment insolvency. The contribution of the project is to draw our attention to possible risks of critical situation development and to propose how to avoid them so that the company will not occur in financial straits. Achieved information could assist the company management to make relevant decisions.展开更多

UNFCCC reports indicate that those who are least responsible for climate change are the most vulnerable to its projected impact and the masses are the ones affected by environmental degradation and lack of access to clean and affordable energy services. This paper therefore addresses the effects of these issues, some forms of energy production in Nigeria and the effects on our environment and how it can be effectively managed through innovative policies and partnership with organizations that can help pilot projects that will build a sustainable energy.展开更多

If we have no access to electricity and depend on traditional biomass fuels to meet household energy demands, it will mean we cannot enjoy the modern energy service. With the deepening international understanding of the issue, many countries have been promoting the practice of eliminating energy poverty, and the "universal access to affordable, clean and sustainable energy" has become one of the post 2015 UN development goals.展开更多

Access to modern energy is essential for the supply of clean water, hygiene and health, and for the provision of reliable and efficient lighting, heating, cooking, and mechanical power. It seems clear, therefore, that the energy factor and its availability, the demand for which is growing, must be ensured over time. Moreover, considering that the world population will significantly increase in coming decades and, legitimately, all of these individuals want access to sources of energy for a better quality of life. The patterns of consumption most commonly used nowadays are expensive and highly polluting, but, most importantly, now they are almost completely exhausted. Therefore, research has to find sources of "alternative" and renewable energy in order to sustain the continuously growing global demand for energy. It is necessary, therefore, to develop and improve policies in order to change current consumption patterns, while strengthening approaches and strategies for sustainable models, applying incentives for good behavior and penalizing waste, and promoting the empowerment of producers. This paper concerns this sector and aims to highlight innovation in bioclimatic and eco-friendly buildings.展开更多

However, China's sustainable agricultural development faces severe tests such as agri-tech "short slabs" and poor collaborative operation. The 12'h Five- year Plan period will bring both strategic opportunities and challenges. Brisker market demands and more agricultural inputs, a higher technical level and better policy regimes will drive development. On the other hand, agriculture will be confronted with more resource and environment constraints, fewer traditional comparative advantages and hidden hazards, etc. Over the next five years, China should stay its course to agricultural modernization based on its national conditions and the sustainable development concept and establish a "broad interpretation of grain security" to improve the productivity, risk- resistance capabilities and market competitiveness of its agricultural industry.展开更多
