In the Sahel of West Africa, the productivities of rangelands, croplands and livestock are inextricably linked. Cattle, sheep and goats graze rangelands and crop residues, and their manure/urine is used to fertilize crops. Rangelands provide important feeds during the manuring period, resulting i...

This conference was conducted to review the development of crop-livestock farming systems in West Africa over the preceding two decades with particular reference to the constraints, productivity, livelihood and environmental impacts; to assess future trends and determine new opportunities for sus...

Poor cropland fertility and a rapidly rising demand for food force Sahelian farmers to cultivate more land and shorten fallow periods. This mostly leads to a gradual decline in crop yields per hectare, which can be counterbalanced by the systematic use of livestock manure on cropland. To assess t...

Integrated natural resource management (INRM) is considered in the context of evolving crop-livestock systems in West Africa and recent Developments in approaches for INRM research. The major crop-livestock systems, ranging from extensive grazing, through integrated crop-livestock farming to inte...

In semi-arid south-western Niger, climatic variability, low productivity, poverty and institutional constraints limit the scope of agricultural production to meet the rising needs of the growing human population. The integration of crop and livestock production activities has long been seen as th...

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...

Forage intake and feeding behaviour of cattle grazing during day and/or night was studied in Sadore between February and May (late dry season) 1995 and, in Toukounous, Niger, between July 1995 and May 1996, covering wet (WS), early dry (EDS) and late dry (LDS) seasons. In Sadore, 24 steers grazed...

Grazing and herd management in sub-Saharan Africa is discussed in a broad ecological, agricultural and geopolitical context. A brief historical overview of the Development of the livestock sector is presented, followed by an assessment of feed supplies and livestock densities in major ecological ...
