In Nigeria, increased land-use intensity has depressed the use of fallow for soil fertility restoration. Crop yields have fallen, threatening food security. High cost limits farmers’ access to fertilizers. Reliance on crop-livestock interaction is plausible because animals provide manure. This pa...

Declining agricultural research budgets coupled with worsening poverty have increasingly required formal priority setting of public agricultural research in developing countries to ensure that scarce research resources are allocated in ways that will have the greatest impact on the poor. This pap...

Traditional shifting cultivation systems can no longer be sustained in West Africa because of rapid increases in human and livestock populations. Short-duration, improved fallows are among the alternative land-management strategies that have evolved. This paper reviews how velvetbean or mucuna (M...

Research was undertaken on the economics of crop-livestock integration in the Northern Guinea Savannah of Nigeria. The aim of the study was to quantify the reciprocal contributions of crops and livestock and also the factors affecting the integration of crops and livestock production in the area....

Agricultural intensification involving greater crop-livestock interactions and integration is emerging as the most promising strategy for improving agricultural production and productivity in much of sub-Saharan Africa. In West Africa, where this process is at various stages of evolution, 559 far...

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 ...
