While many pastoral regions are the focus of current desertification studies the long history of sustainability evidenced by these cultures is of great interest. Numerous studies suggesting a general trend of desertification intimate degradation is a recent phenomenon principally attributable to changes in land tenure management and treatment. This paper explores the suggested causes of land degradation and identifies the land management and grazing treatments shared by many pastoral cultures. The singular commonality found in nearly all studies of degradation is the prevalence of partial or total rest. While historical observations rightly suggest that desertification is the result of both climatic and anthropic factors recent focus has been placed upon the effect of sedentarisation. This paper attempts to coalesce these two streams of thinking with particular focus upon inclusive planning processes which may improve arid and semiarid rangeland ecosystems using livestock as a solution to the problem of land degradation.
