If camels and other stock can be based far away from a water source, the total area available for grazing is greatly increased, the stocking rate can be lowered and the dangers of environmental degradation are reduced. In simple terms, a doubling of the interval between successive visits to water results in a four-fold increase in the area available for pasture, with a corresponding reduction in grazing pressure. More especially, the time period between successive waterings has an important bearing on the carrying capacity and the degradation risk of a given area. If for example, the number of.
