Abstract
The Soil Loss Estimation Model for Southern Africa (SLEMSA) model integrated with Remote Sensing (RS) and Geographical Information Systems (GIS) was positively validated to spatially assess soil erosion risk in the Taung Watershed of Ramotswa Agricultural District during the period 2000 – 2020. The estimated annual soil erosion averaged 11.77 and 12.57 t/ha/year in 2000 and 2020, respectively. The Land Use/Land Cover (LULC) and topography were found to be key determinants of high soil erosion risk when using SLEMSA. The soil erosion assessment tools enabled prioritization of high erosion prone areas in the study area for soil conservation planning and watershed management.
