Inco-prorating the community based management project in rural development strategies seems to be the best approach to implement rural development project. The study used both qualitative and quantitative research techniques to obtain data on the implementation of LEEMP （local empowerment and environmental management project）. The result shows that the project has impacted positively to rural development of some rural communities in the state. However, there were challenges discovered, which include non-inclusion of some stake holders because of social class or due to political affiliations, while projects are not evenly distributed among communities of serious needs. This paper implies that effective incorporation of rural communities in the managements of rural development projects requires full community participation in the development process. This requires collective action, which ties the community on values, sustainable maintenance of infrastructures, and improvements, in cultures, of environmental conservation and economics benefits into rural development, with balancing the aim of sustaining social infrastructures, environmental management and poverty alleviation.展开更多

This necessitated eutrophication to occupy a front seat in research accompanied with climate change. Climate change has revealed to be a key player and a main contributor in the occurrence of such phenomenon. This paper discusses the ever-growing concern about eutrophication as a cause of climate change. Climate change affects storms intensity, changing the precipitation regime and increasing temperature. These effects increase the nutrient loading diffusion and cause excessive nutrients accompanied with storm water runoff, domestic wastewaters, and agricultural discharges to pour into water bodies. Eutrophication conversely contributes in the global wanning by releasing greenhouse gases from deoxygenated waters and sediments. Some control and mitigation measures are needed to fight climate change and achieve desired water quality goals. These measures include mitigation of climate change causes, enhancement of natural ecohydrological processes, application of proper integrated water resource management and participation of communities and governments.展开更多

Numerous complaints have already been filed against the EIA, challenging the scientific integrity of the report on the following grounds： misrepresentation of failure to specify the radioactive inventory and of projected releases into the environment, omitting tritium and carbon-14; incomplete information about the toxic chemicals which will be injected into the cooling system throughout the nuclear complex; misleading information about the cooling water＇s temporal and chemical effects on marine life; lack of details on an emergency evacuation plan; lack of a comprehensive nuclear waste management plan; unspecified insurance coverage for the nuclear complex, noncompliance with third party liability requirements. Coupled with these complaints are allegations that signatures on some sensitive reports contained or referred to have been falsified.展开更多

According to the level of corporate environmental management, there are many influential factors, and their relations are also complicated. In this paper, we analyzed influential factors of corporate environmental management through consultation of experts. And based on the analysis, we applied interpretative structural modeling（ISM） to classify 13 influential factors into 3 levels. We hope it will be useful for the subsequent research and evaluation of corporate environmental management level.展开更多
