Soil erosion is the most serious environmental problem in many catchments areas in Rwanda. The main factors affecting the amount of soil eroded include land use and vegetation cover, topography, soil and climate. In order to identify area of potential soil erosion risks and to develop adequate erosion prevention measures for Rwanda, a National erosion risk map was generated and validated in July 2018 based on a methodology known as “Catchment Restoration Opportunity Mapping (CROM)”
