Discusses the historical context of ILCA's research, the principal types of animal production systems and the stages in ILCA's farming systems research. Describes the smallholder farming in the Ethiopian highlands & humid zone, the agropastoralists of the sub-humid zone, systems research in pastoral areas of eastern Africa (Kenya & Ethiopia), characteristics of the arid and semi-arid zones of West Africa and the role of modelling in the system. Ends with a summary of past experience.

Presents results of studies of settlement, land use & relations w. settled farmers of Fulani agropastoralists in Abet & Kachia Grazing Reserve in Subhumid Nigeria. Discusses reasons of choice of site, pattern & right of grazing and access to land.

A trial conducted to examine the effects of watering Boran cattle once daily, once every two days and once every three days on birth and weaning weights, post-weaning growth and cow performance under extensive grazing conditions.

Describes effects of feeding Bunaji cows supplements of cottonseed cake, molasses-urea or fodder bank on birth & 1-year weight of calves and their viability to 1-year, and milk yield, for both calves & humans, of cows under an agropastoral management system.

This paper examines a process - the spontaneous enclosure of the range by livestock owners - which may rise new problems but also permit new approaches to the development of the African livestock industry. Drawing on case material from Sudan and Somalia, the opening section of the paper discusses some of the spontaneous range enclosure.

Discusses the results of the measurement of environmental changes in grazed ecosystems with reference to correlated changes in livestock management in Kenya; includes techniques used to measure the changes, and proposed methods; presents data on a case study at a group ranch located in western Kenya which covers 50,000 ha.; ends with comparison of surveys, i.e., that of 1978 and 1981.

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.

Explains to what extent effective traditional African range management systems exist/existed, and discusses the factors which influence their incidence, persistence or effectiveness - focussing principally on sub-Saharan Africa.

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.

This paper examines the decline of common property resources in the arid zone of Rajasthan in India and the factors underlying the decline.The article concludes that:well-intentioned public programmes like land reformcan deprive a region of its comparative advantage in a key economic activity (in this case livestock farming)privatisation raises the cost of livestock raising and, hence, erodes the the region's comparative advantagethe continuing shrinkage and degradation of common property resources is likely to force further reduction in the size of livestock holdings and changes in their c
