    In 1986, ILCA carried out informal surveys at Dogollo and Inewari in order to understand the farming systems. Such surveys were also conducted by the Institute of Agricultural Research (IAR) at Ginchi in 1986 and by the Alemaya University of Agriculture at Ada/Debre Zeit in 1988/89. This was followed by one-time detailed formal farm surveys at Dogollo, Inewari and Ginchi in 1988/89. This chapter mostly presents the results of these formal surveys.

    As the only international centre that is solely concerned with African livestock, ILCA has a responsibility to play a lead role in defining the agenda of research issues related to livestock development and environmental policy in Africa. This paper presents a framework appropriate for defining that agenda and for guiding analysis of particular research issues and gives some detail on how ILCA might approach the specific area of range management policy in the arid and semi-arid areas.
