Abstract
The overall soil erosion potential of the Nsikazi area in Mpumalanga Province, South Africa, was determined using the bare soil index (BSI), derived from satellite imagery and geo-spatial information from various sources in a geographic information system (GIS) environment. By integrating a BSI map with a natural soil erosion potential map for the study area, an indication of the causes of soil degradation was obtained. Land-use patterns were also used to identify the specific human activities that caused the most extensive soil erosion. Spatial information about the extent and causes of soil erosion is essential for the effective implementation of soil erosion prevention programmes.
