Desertification of the Eastern Karoo, South Africa: Conflicting Paleoecological, Historical, and Soroo hypothesis as well as the argument that the Karoo’s carrying capacity has decreased in recent years. Finally, the relative responsibilities of humans and climate in the degradation process remain poorly understood and generally have not formed the focus of investigation.

Desert soils may recover slowly from surface disturbances, resulting in increased vulnerability to

Successfully applying this approach revealed the importance for land degradation of the close linkage between spatial patterns and hydrological
