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

The system combines data bases and GIS and a range of coupled models and analytical tools that address a range of typical management problems and cover several levels of nesting from regional to city level and street canyons. The main functions are to support regulatory tasks, compliance monitoring, operational forecasting and reporting, impact assessment EIA （environmental impact assessment）, SEA （strategic environmental assessment） and public information within one consistent framework. A major objective is the improvement of air quality through emission control. The integrated model system together with its shared data bases provides a reliable, consistent basis for the non-linear techno-economic and multi-criteria optimization of emission control strategies （including greenhouse gases and energy efficiency）. A real-time expert system drives, supports and monitors the autonomous and interactive operations, and provides embedded QA/QC （quality assurance/quality control） functions for reliable operations and ease of use.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
