The concept of industrial ecology has been applied in this research to study possibilities to develop an eco-industrial cluster model for fishery production industry in Vietnam. By learning from experiments of other developed countries, we apply the principles of Industrial Ecology and of Ecological Modernization in the context of Vietnam. We design a physical-technological conceptual model for minimizing waste in agro-industries, with a case study of frozen shrimp production. The results indicate that it is possible and feasible to develop an eco-industrial cluster including aquaculture, fishery processing companies, by-product plants, and wastewater treatment units. By doing so, aquaculture and industry can cooperate for environmentally sound development. Actors and institutions that may govern the proposed eco-industrial cluster of shrimp processing industry are also analysed in this paper. The economic feasibility of the designed eco-agro industrial cluster for fish production in Vietnam depends on the energy savings and effective revenues gained from selling the produced valuable materials, such as Chitosan and animal feed. 相似文献

Drivers of Forest Cover Dynamics in Smallholder Farming Systems: The Case of Northwestern Vietnam 总被引:1,自引:0,他引:1
The national-scale forest recovery of Vietnam started in the early 1990s and is associated with a shift from net deforestation to net reforestation. Large disparities in forest cover dynamics are, however, observed at the local scale. This study aims to unravel the mechanisms driving forest cover change for a mountainous region located in northwest Vietnam. Statistical analyses were used to explore the association between forest cover change and household characteristics. In Sa Pa district, deforestation rates are decreasing, but forest degradation continues at similar rates. Deforestation is not necessarily associated with impoverished ethnic communities or high levels of subsistence farming, and the largest forest cover dynamics are found in villages with the best socio-economic conditions. Our empirical study does not provide strong evidence of a dominant role of agriculture in forest cover dynamics. It shows that empirical studies on local-scale forest dynamics remain important to unravel the complexity of human–environment interactions. 相似文献

Groundwater is an important resource in the alluvial coastal lowland plains. In the Shiroishi lowland plain, southwestern
Kyushu Island of Japan, land subsidence due to groundwater development has long been recognized as an environmental issue.
Land subsidence can have several negative economic and social implications. In this study, an integrated numerical groundwater
and land subsidence model, which combines a three-dimensional numerical groundwater flow model and a one-dimensional soil
consolidation model, was used to simulate the dynamic groundwater flow and ground subsidence due to pumping. On the other
hand, a groundwater optimization model was also formulated to search for an optimal safe yield of groundwater pumping without
violating physical, environmental, social-economic constraints. The model results reveal that groundwater levels in the aquifers
greatly vary from season to season in response to varying climatic and pumping conditions. Consequently, land subsidence has
rapidly occurred throughout the area with the central prone in Shiroishi plain. The study also proposes a countermeasure against
subsiding process in the area by means of numerical models. The optimization model result suggests that pumping can be increased
in the northern part of the study area without leading to significant land subsidence. 相似文献

The concept of school-based disaster risk reduction (DRR) education has increasingly become popular as greater emphasis is placed on the role of schools in reducing risks and building the resilience of the education system. This paper discusses the variations in the implementation of DRR education among primary schools in different areas including urban, rural, mountainous, plain and coastal areas in Da Nang City, Central Vietnam. For rural schools, similarities in the implementation of DRR education are observed and schools in both rural plain and rural mountainous areas stress the provision of disaster-related training. In addition, improvement of school buildings and external relationship is important for the resilience of urban schools. Specifically, for schools in urban coastal areas, school location and structure are significant, while for schools in the urban plain lands, enhancement of collaboration with their community has the most potential to contribute to the resilience of a school. From that, this research proposes that leadership and prioritization are key factors in helping schools to manage internal and external resources to efficiently overcome challenges and effectively promote DRR education towards the enhancement of schools’ resilience. 相似文献

Eco-industrial networking is considered as a new approach for businesses to improve their competitiveness, economic viability and human and ecosystem health. A cyclic material flow with alternative usage of all materials in the loop is an essential feature of an eco-industrial network. While eco-industrial networking has been primarily applied on the high-tech sector, this paper attempts to apply the principles on the fishery sector of An Giang, a Vietnamese province in the Mekong River Delta. An Giang Province has its own market share in the trade of Tra and Basa fish. The industries in the value chain of Tra and Basa are in a situation that forces them to improve their competitiveness to retain the market share. It was found that forming an eco-industrial network and recruiting new businesses to utilize all materials in the process provides additional revenue apart from reducing waste disposal concerns. This paper details the current market situation, the issues faced and material flow patterns and presents a feasible eco-industrial network. The results of the study indicate that the eco-industrial network creates positive impacts in terms of increased competitiveness, improved socio-economic conditions and cleaner environment. 相似文献
