Degradation of the range in pastoral economies is widely put down to the existence of a "common property problem" (CPP) arising out of communal ownership and leading to excess holdings of livestock. Examining first the reasons for accumulating livestock in traditional livestock systems, this article looks more closely at the physical processes of range degradation, reviewing recent literature, and argues that inadequate account has been taken of the difference between average rainfall years and drought and immediate post-drought years in which degradation under the CPP, if it occurs will be concentrated.
