Optimal long-term stocking rates for livestock grazing in a Sahelian rangeland

A recent paper in the African Journal of Agricultural and Resource Economics presents a model for calculating the optimal livestock stocking rate in a semi-arid rangeland that accounts for stochastic rainfall, the ecological feedback effect and variable prices.

The model is developed for rangelands dominated by annual rather than perennial grasses, such as the African Sahel. The feedback effect is modeled on the basis of an ecological study, conducted in northern Senegal, that analyzes the impact of different grazing pressures on vegetation productivity.
