The use of remote sensing in quantifying rates of soil erosion

Abstract

A remote sensing technique is applied in the quantification of the aereal involvement and rates of spread of sodic sites in the upper Ripape River drainage basin of the Kruger National Park. The results show changing areas of sodic site erosion over a period of 41 years. Possible cause and effect relationships are not discussed but the magnitude of soil loss suggests that the erosion has progressed at a rate which is in excess of the rate of natural denudation, under the prevailing climatic regime.
