This report highlights ILCA's work in the past, and discusses current activities and future plans with particular reference to mixed crop-livestock systems, market-oriented smallholder dairying, conservation of biodiversity, biological efficiency of livestock, livestock production under trypanosomiasis risk, livestock and resource management policy, and strengthening national research capacitie

The impact of human endeavours on the environment in the struggle to eke out a living through crop and animal agriculture is examined in a holistic context. Analyses focus on all the sources of pressure that modify the vegetation cover of rural Africa, including the effects of fires and burning of biomass, fuel wood extraction and deforestation and land clearing.

Achieving sustainable increases in agricultural production in sub-Saharan Africa is both a regional and a worldwide concern. High human and animal population densities in some areas have surpassed

This volume contains an executive summary of papers and the discussions on them as well as the reports of working groups and the recommendations of the Roundtable on Livestock Development strategies for Low Income Countries.

Watershed management involves the integrated management of a multitude of resources such as crop land, pastures, forests and water to each of which a multitude of often conflicting interests relate. These interests arise from stakeholders inside as well as outside the watershed. The identification and negotiation of these interests therefore is an important element in watershed management.

This workshop was conducted to identify and prioritise areas of rumen ecology which are promising for their potential impact on improving nutrition status of tropical ruminants, to develop a rumen ecology research programme for ILRI based on relevance to developing countries and ILRI's comparative advantage vis-a-vis other institutions, to identify potential collaborators in advanced research

In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years.

The integration of crops and livestock has often been cited as a model for agricultural development in semi-arid West Africa. Recent formulations treat the adoption of more intensive forms of manuring as a critical step in agricultural development.
