Deforestation in the Serayu watershed, Central Java province, Indonesia for agriculture and other uses leaves only 0.73% of vegetation. It has triggered a number problems such as soil loss (erosion), landslides, floods sedimentation downstream. Environmental damage control needs to be applied through appropriate conservation programs. This study aims understand distribution erosion effectivenes...

The Three Gorge Project (TGP) of China necessitates the resettlement of over 1 million population (mostly farmers) to more rugged and isolated areas than their original settlements. Soil erosion is a serious environmental and production problem in this area. To decrease the risk on environmental impacts, there is an increasing demand for sound, and readily applicable techniques for soil conserv...

Understanding soil erosion in the northeastern area of China with black is vital for protecting natural environment and preserving food security. Although spatial temporal studies have been conducted, further research needed on correlation between land use type changes. In this study, modulus computed using RUSLE. The model that most suitable to was produced by contrasting three different appro...
