    This study assesses, in an indicative way, the impact of fodder banks and forage legume technology in countries of West Africa. The economic surplus method is used to estimate the social rate of return to public investment in research on fodder banks and the distribution of that return amongst producers and consumers. Subsequent sections of this report describe the technology of fodder banks, the economic surplus method, sources of data and the results of the analyses.

    The major objectives of this workshop are to sharpen the focus of ILRI's ecoregional research, to further identify commonalities in tools and new methods that can enable ILRI to do effective transregional research, and to identify improvements to the way in which ILRI does ecoregional research.

    A short-term improved fallow system based on forage legumes is suggested for crop-livestock farming systems in subhumid West Africa targeted to enhance soil fertility and dry season feed for cattle. At two sites, 13 legume species were compared with the natural fallow vegetation, the nutritive value of which typically fails to meet cattle requirements during the dry season. Establishment, dry matter yield and nutritive value of leguminous herbage in the year of establishment were evaluated as well as regeneration of legumes after a cropping phase.

    A short-term improved fallow system based on forage legumes for enhancing crop and livestock components of mixed farming systems was tested in the subhumid zone of West Africa. As part of the evaluation, the ability of 11 legume species (Centrosema macrocarpum, C. pubescens, Stylosanthes guianensis, Pueraria phaseoloides, Mucuna pruriens, Zornia glabra, Dioclea guianensis, Arachis pintoi, Aeschynomene histrix, Calopogonium caeruleum, Flemingia macrophylla) to accumulate biomass and nitrogen after dry season harvest of herbage was assessed at 2 sites in south-west Nigeria.

    In a short-term improved fallow for crop-livestock farming systems of subhumid west Africa, rotational effects from a range of forage legumes on a subsequent maize crop were studied at two sites in south-west Nigeria. Nutrient (nitrogen, phosphorus and potassium) export from the fallows in the form of dry season herbage and subsequent nutrient accumulation in the green manure biomass were correlated with growth patterns of maize subsequently grown on the legume plots.

    The purpose of the project "Increasing livestock productivity in mixed crop-livestock systems in South Asia" is to develop a crop-livestock typology that will ultimately improve the effectiveness of technical and socio-economic interventions aimed at improving animal performance and protecting the natural resource base at farm level in South Asia.

    The Borana people are the predominant ethnic group on the Borana plateau in southern Ethiopia. Though traditionally transhumant pastoralists, they have recently increased their reliance on crops. Rainfall in the region averages between 353 and 873 mm; variability is high, with coefficients of variation ranging from 0.21 to 0.68. Anecdotal evidence implies that the vulnerability of pastoralist households to drought is increasing; stock levels increase dramatically during good rainfall years but plummet when rainfall is poor, indicating that the drought cycle is becoming more pronounced.

    The aim of this workshop was to consider methods of immunisation against East Coast Fever (ECF) and other forms of T. parva infection using the infection and treatment method or infection without treatment, and to identify needs for further research to improve vaccine quality and suitability; to consider present and future demands for T. parva vaccine and how these can be met; to review recent progress in developing alternative vaccines for the control of theileriosis caused by T. parva, to consider related research needs, and to identify training and information needs.
