This paper deals with foraging behaviour of cattle grazing semi-arid rangelands in the Sahel of Mali. It discusses the location of study site, vegetation in the grazing orbit, herd management and livestock behaviour. Results on seasonal variation in feed supply, selection of the annual grazing or...

Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain l...

In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis,...

The sustainability of nutrient transfers in integrated rangeland/cropland systems of the Sahel was examined in relation to the impact of livestock. Rangeland nutrient balances are considered in equilibrium whereas croplands lack the internal capacity to replenish nutrient off takes in grain and c...

Discusses the aim of studies on vegetation & feed resources in pastoral systems, describing the collection & presentation of data in the descriptive phase; identification of constraints in the diagnostic phase; and analysis of the impact of selected variables or technical innovations on the syste...

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...

LaHiernaux, Pierre H.Y.Keulen, H. van[Options for intensification of mixed crop-livestock systems in rural communities of south-western Niger: Prospects and constraints]Options for intensification of mixed crop-livestock systems in rural communities of south-western Niger: Prospects and constraints

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...

Night corralling of livestock directly in crop fields during the dry season contributes to nutrient cycling for the benefit of crops. Rangeland grazing and corralling livestock on selected croplands result in a spatial transfer of organic matter and nutrients from rangelands to the corralling sit...
