Applying geospatial technology to identify soil erosion risks in the context of climate change in Yen Chau district, Son La province

This article presents the results of applying geospatial technology to assess soil erosion for Yen Chau district. Geospatial Technology was applied to build maps of factors affecting soil erosion such as: rain erosion coefficient map (R), soil erosion resistance coefficient map (K), terrain erosion coefficient map (LS), cover erosion coefficient map (C) and farming practices (P). Improved universal soil loss equation (RUSLE) due to Wischmeier and Smith was used to create soil erosion maps.
