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...

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...

Conference Paper 1997

Autor: Williams, Timothy O. Hiernaux, Pierre H.Y. Fernández Rivera, S. Turner, M.

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...

Autor: Fernández Rivera, S. Hiernaux, Pierre H.Y. Kaufmann, Ralph R. von Turner, M. Williams, Timothy O.

Three papers are reviewed in this paper. The first paper presents a model of biological processes to investigate long-term effects of soil and crop long-erm effects of soil and crop management strategies while the other two papers present approaches to study crop production strategies at the ente...
