Such is the vagary of rainfall throughout Africa's rangelands that almost all pastoral communities face cycles of good and hardship years. During good years herders increase and diversify their herds, whilst consecutive hardship years or `pastoral drought,' human and livestock disease, or livestock theft may result in large livestock losses and the consequent temporary collapse of household food production.

This article looks at the changes which are taking place in the Syrian semi-nomadic bedouin flocks' feeding and migration patterns, and the historical reasons for these changes. Most of the discussion will focus on three steppe-based villages in northern Syria, where the International Center for Agricultural Research in Dry Areas (ICARDA) undertook a three-year survey between 1978 and 1981, and where a follow-up study was done this year.

Library Resourcejanvier, 1993Botswana, Afrique sub-saharienne
Recent arguments have stated that the new livestock development policy will carry a high social cost, that the reality of range degradation in Botswana has been ignored, and that there is no basis for assuming that de-stocking would decrease the productivity of rangeland.

Library Resourcejanvier, 1993Botswana, Afrique sub-saharienne
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).
