Abstract
The farm Gamis is located about 250 km SW from Windhoek at the edge of the Namib. Mean annual precipitation is 177 mm with enormous fluctuations in space and time. Extensive pastoral agriculture is supposed to be the appropriate type of land use in this ecologically sensitive region where much of the land is now degraded due to overgrazing in the past. At the Gamis farm, Karakul sheep are kept for the production of furs. The farmland (30000 ha) is divided into 98 paddocks, approximately 60 of them are used for the grazing of (up to three) fur production flocks. A sophisticated grazing rotation system has prevented the land from degradation, at the same time guaranteeing the farm's econo
