    RAINFALL, PRIMARY PRODUCTION AND THE PROBLEM OF CARRYING CAPACITY IN THE SEMI-ARID ZONE OF NIGERIA,
    (Department of Geography, Nasarawa State University Keffi, 1999-07-01) Ayuba, H.K.; Maryah, U.M.; Bdliya, B.S.
    Interannual variability of rainfall and its effects on forage and livestock productivity on the rangelands of the arid zone of North East (N.E.) Nigeria poses basic questions regarding the sustainability of the system under variable rainfall regimes, and creates difficult management problems for the ' pastoralisls who depend on the system for their livelihood. There is a considerable debate in relation to the likelihood or otherwise of global changes in rainfall regimes as a result of increasing temperature levels consequent upon higher concentrations of greenhouse gases (GHG) (for example Gordon el al., 1994, Mitchell and Williams, 1986; and Watson el al\ 1988). In addition there is a lot of uncertainty concerning the regional effects of such climatic changes upon agriculture (Parry and Carter, 1988; Mitchell el al 1996), and particularly on livestock production.
