    Botswana, 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).

    Botswana, 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.

    République arabe syrienne, Asie occidentale, Afrique septentrionale

    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.

    This papers examines the trade and price trends for livestock products emerging for the 1990s in sub-Saharan Africa, the issues that these trends present for policy research, the potential impact of research that addresses the identified issues, and wheather ILCA have a comparative advantage in undertaking work on the identified issues and wheather there are potential collaborators to work with. The issues and areas identified constitute a modest set of suggestions for future research.

    Éthiopie, Afrique, Afrique orientale

    The Borana plateau of southern Ethiopia: synthesis of pastoral research, development and change, 1980-91 summarises results from work conducted by 40 people in the southern Ethiopian rangelands between 1980 and 1991. The first chapter reviews rangelands and rangeland development in Ethiopia. The second chapter is an introduction to the Borana plateau: natural resources and pastoral society. The next three chapters deals with vegetation dynamics and resoruce use, Borana household economy, and livestock husbandry and production.

    This volume contains papers and abstracts of the Second Biennial Conference of the African Small Ruminant Network. In addition to the keynote address, there are nine papers on Small Ruminant Production Systems, Economics and Policy, nine papers on Small Ruminant Performance and Reproduction, ten papers on Small Ruminant Health and Reproductive Wastage, eight papers on Small Ruminant Feeds and Feeding Systems and eight papers on Small Ruminant Genetic Resources and Breeding. Ten poster abstracts covering the above topics add to the volume.

    Mali, Afrique, Afrique occidentale

    This chapter investigates the options for improving the performance of small ruminants interms of their contribution to household incomes. The characteristics of the existing production system are first sketched in order to identify the resource requirements and constraints of the system. Based on this imformation, a steady-state flock model is then developed and used to assess the impact of variation in growth, reproduction and mortality rates production.
