    Botswana, África subsahariana

    A useful debate is developing over carrying capacity and the degradation of communal rangelands in sub-Saharan Africa. With a few lonely exceptions, scientists and policy-makers have in the past claimed that degradation is universal and livestock productivity lowered because of overstocking on communal range. This position has been mainly dogmatic. More recent research has not supported dogmatists; hence the debate, which impinges on livestock development policy in Botswana.A new livestock development policy is being promoted by the Government of Botswana (Ministry of Agriculture 1991).
