This paper evaluates in a comparative cross-country context, the objectives and instruments of livestock pricing policy in five sub-Saharan African Countries: Cote d'Ivoire, Mali, Nigeria, Sudan and Zimbabwe during the period 1970-86. It assesses the extent to which pricing policy objectives have...

Classification constitutes an essential step in any realistic evaluation of the constraints and opportunities that exist within a farming system. In this study, cluster analysis was used to classify crop-livestock producers in three villages in western Niger into recommendation domains using a co...

Degradation of crop and grazing lands is a pervasive problem that negatively impacts agricultural productivity and livelihoods of crop-livestock farmers in the Blue Nile basin of Ethiopia. Area enclosure together with a cut and carry livestock feeding system is often advocated as an approach for ...

Animal manure is of vital importance in maintaining soil fertility in semiarid west Africa due to the low level of use of inorganic fertilizer. Using data from Niger however, it is shown that insufficient animals are available to provide the manure needed to sustain crop yields on a long-term bas...

Soil fertility maintenance and food crop production in semi-arid West Africa: Is reliance on manure a sustainable strategy?
Despite its vital role in supporting crop production, a key question that has often been posed is whether sufficient amounts of manure are available to permit adequate food production and improvement of soil quality on a long-term basis. While this question can be addressed at a regional, nationa...

The use of animal draft power for soil tillage has long been a major theme of agricultural development programmes in semi-arid West Africa. The rationale for animal traction utilization ranges from increasing agricultural productivity and income to relieving the drudgery in farm work. Yet, its ad...

Crop-livestock integration (CLI) to improve natural resource management for increased productivity is evolving in Nigeria and West Africa. Processes in the evolution and factors that influence it still need to be well understood. This article proposes and tests a new framework for measuring the m...

Animal manure is one of the principal sources of nutrients for soil fertility maintenance and crop production in semi-arid west Africa. Farm-level decisions concerning the use of manure are governed by socioeconomic and institutional factors, as much as they are by agronomic ecological concerns. ...

This paper examines the water dimensions of recent large-scale land acquisitions for biofuel production in the Ashanti, Brong-Ahafo and Northern regions of Ghana. Using secondary sources of data complemented by individual and group interviews, the paper reveals an almost universal lack of conside...

As institutions that facilitate the conversion of livestock to grain and adjust livestock populations to local forage availabilities, livestock markets play important economic and ecological roles in dryland Africa. Using a comprehensive database of 1,580 sales of livestock owned by members of 54...
