    Kenya, Mali, Éthiopie, Afrique, Afrique orientale, Afrique occidentale

    Describes the dif. phases in the ILCA research framework, w. regard to Livestock Systems Research (LSR), particularly the descriptive, diagnostic, design, testing & extension phases, using examples of field research on pastoral & agropastoral systems in the arid & semi arid zones of Mali, Ethiopia and Kenya.

    Nigéria, Afrique, Afrique occidentale

    Describes, briefly, sizes structures, general management and productivity of pastoral herds in the Kaduna Plains of Nigeria. Includes data on age at first calving, calving percentage, calving intervals, calf liveweight & mortality to 1 year, and milk yield of Bunaji cattle under this sedentary pastoral management system. Identifies nutrition as cause of this below-genetic-potential productivity.

    Mali, Afrique, Afrique occidentale

    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. To test this hypothesis, fertiliser trials were carried out at sites distributed along the bioclimatic gradient in the Gourma (Mali) over contrasting rainfall years between 1988 and 1992.

    Nigéria, Afrique, Afrique occidentale

    Summarises the performance of three species of stylosanthes, viz, S. guianensis cvs Cook and Schofield, S. hamata cv. Verano and S. humilis under different production systems in Nigeria, such as in pure legume pastures, mixed pastures, with crops, in rangeland and under seed production.

    Afrique, Afrique occidentale

    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. These analyses have been criticised for ignoring or underestimating the possible negative consequences of such management on rangeland and livestock productivity. This paper critically examines this debate. It is argued that the agronomic benefits of manuring depend largely on nutrient transfers from non-cropped grazing lands.

    Nigéria, Afrique, Afrique occidentale

    Describes the geology, relief, climate, major soil types, vegetation zones and land use patterns of the subhumid zone of Nigeria. Presents results of studies on natural forage productivity & composition and forage production constraints.

    Afrique, Afrique occidentale

    This report is divided into seven sections. The first section deals with biology of Stylosanthes and its importance in West Africa and Latin America. The second section presents papers on the screening and evaluation of Stylosanthes germplasm. This includes genetic diversity, genetic resources, species screening, multi-locational testing and evaluation of accessions. The third part discusses the dynamics, nutrient requirements, and pests and diseases of Stylosanthes species. Section four looks at Stylosanthes-based pastures for livestock production.

    Afrique, Afrique occidentale

    The report is divided in 12 sections. The first section is introductory. The second section presents research on animal health of working animals. Diversified uses of animal traction including animal-powered rice-huller, weed control are discussed in the 3rd section. The fourth section looks into harnessing and implements used in the different regions of West Africa. The management and nutrition of working animals is discussed in the fifth and sixth sections.

    Nigéria, Afrique, Afrique occidentale

    Presents an overview of population and land use characteristics of the Kurmin Biri, Abet and Ganawwi areas, all in the subhumid zone of Nigeria, with particular reference to ethnic composition, human & cattle population, cultivation densities and extent of fallow land.

    Niger, Afrique, Afrique occidentale

    In semi-arid south-western Niger, climatic variability, low productivity, poverty and institutional constraints limit the scope of agricultural production to meet the rising needs of the growing human population. The integration of crop and livestock production activities has long been seen as the most promising means for intensifying agriculture and improving productivity and food security. Livestock play key roles in mediating soil fertility through excreting manure and grazing crop residues and distant pastures.
