Description :
Gully erosion is an important form of soil erosion that contributes greatly to soil degradation and loss in South Africa. Little is known regarding the spatial extent of gullies at a national level. A gully location map was compiled from SPOT 5 imagery. It was found that gullies are more prominent on land that is suitable for cultivation (4.3%) than on less suitable to unsuitable land (1.5%). Possible reasons are suggested and future programmes indicated. - (AJC)
