We have studied on the harmonization of development and environmental conservation in Cidanau watershed of West Java, Indonesia, where the natural environment has been getting worse recently, and we have reported some results of three topics. One is a report on the socio-economic change and the recent environmental change by studying literatures and field surveys. Second is a report on green vegetation change and land use change in Cidanau watershed by using remote sensing images observed in 1994 and 2000. The last is a report on hazard mapping of soil loss in Cidanau watershed by using GIS, based on USLE. Based on these research, we conclude following findings. 1) Large area of forest near Rawa Danau, which is tropical pure water swamp forest and registered as a green belt, had been deforested accompanied with the increment of population from 1994 to 2000. 2) Some small scaled developments were occurred in other places such as sloped lands, but they had low risks of soil loss from the view point of soil conservation in the whole watershed. Finally, we conclude these results and summarized, the characteristics of the land use change and environmental change in this area. After that, we refer the significance of environmental policies such as environmental education or improvement of land registration system.
