SOIL EROSION RISK DETECTION BASED ON REVISED UNIVERSAL SOIL LOSS EQUATION (RUSLE) IN THE COPPERBELT WATERSHED, ZAMBIA

Abstract

Despite the general concerns of soil erosion as a major cause of land degradation emanated by human activities and natural settings, information on soil loss is not readily available in some areas under different land use systems since no studies have been done to establish the erosivity of the land. An attempt was made to identified potential vulnerable areas to soil loss  in the Copperbelt province using RUSLE model with remote sensing and GIS. The study revealed insignificant risk of soil loss for the entire study watershed.  The cell soil loss value estimated for the entire study watershed was 0.0000000011 ton/ha-1/yr-1and the area location, which exhibited high vulnerability to soil loss thus high erosion hotspot was found in the Mpongwe District and we recommend that detail study is required in the district in order to detect actual areas to soil loss. This may help to appropriately design soil conservation strategy to surmount the soil erosion problem in the district.
