Mixed farming systems, combining crop and livestock activities, hold considerable promise for improved agricultural productivity and environmental conservation in semi-arid West Africa. Increasing population pressure and climatic changes have combined to render long-fallow periods less feasible a...

This chapter investigates the options for improving the performance of small ruminants interms of their contribution to household incomes. The characteristics of the existing production system are first sketched in order to identify the resource requirements and constraints of the system. Based o...

A classification of the major ruminant livestock production systems in West Africa is proposed. The proposed typology has two major classes of systems-sole livestock and crop-livestock. The sole livestock class has two systems (rangeland-based and landless) and the crop-livestock class has three ...

Animal manure is of vital importance to soil-fertility maintenance in semi-arid West Africa due to its intrinsic value as a soil amendment and because of the low level of inorganic fertiliser use. This paper provides a regional overview of manure utilisation for food crop production. Results of e...

Livestock pricing policies in many developing countries are often instituted without a good appreciation of the consequences of such policies for allocative efficiency, output, trade and consumption. This paper evaluates, in a comparative cross-country context, the objectives and instruments of l...

The livestock subsector (LSS) has always been an important component of the Nigerian economy. Despite the importance of the sector, growth in livestock output has been slow. In the face of constraints posed by disease and ecological problems, government policies have not been totally successful i...
