This chapter describes seasonal herd movement and resource use in a pastoral Himba community in north-western Namibia. In this grazing system, livestock tend to occupy those areas best suited to their needs in a particular season. The self-interest of herd owners, the natural inclinations of the animals, and the dictates of the ecology are therefore routinely sufficient to enforce orderly patterns of stock movement and resource use. The perennial pastures used for dry-season grazing are the major exception to this rule. These pastures provide good grazing throughout the year, and group discipline is required to ensure their preservation. The local institutions that provide this discipline are described, and their capacity to cooperate with government authorities to develop and manage new water-points is assessed.
