Conference Paper 1996

Autor: Powell, J.M. Fernández Rivera, S. Hiernaux, Pierre H.Y. Turner, M.

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...

In much of rural Africa, livestock represent one of the major individual stores of material wealth. The way in which this wealth is perceived and used will have an important effect on the prospects for sustained agricultural Development and resource management. The study of the changing socio-eco...

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...

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...

The integration of crops and livestock has often been cited as a model for agricultural development in semi-arid West Africa. Recent formulations treat the adoption of more intensive forms of manuring as a critical step in agricultural development. These analyses have been criticised for ignoring...
