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...

The livestock revolution is occurring but it is being preceded by the feed revolution because of the substantial mount of feed required to supply by the increased animal population. However, the opportunities to meet the demand for feed depend on the existing production systems. This paper looks ...

Over the last two to three decades, West Africa has witnessed considerable changes in land use. Unprecedented increases in human population combined with changes in climatic patterns have reduced per capita arable land traditionally available for agricultural production. In the livestock sub-sect...
