There has been little experimental work in West Africa that distinguishes grazing from climate effects on rangeland vegetation. In the absence of such Knowledge, the recurrence of boom-bust cycles in livestock populations, along with the seemingly degraded state of semiarid range, have been used ...

Overstocking the range: A critical analysis of the environmental science of Sahelian pastoralism
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...

Nutrient cycling in integrated rangeland/cropland systems of the Sahel
Over the past 10 years, mobility of livestock has been portrayed as increasing the resilience of rural households in semi-arid Africa to climate change and variability. With this recognition, there has been important work characterizing livestock mobility and the barriers to it. This paper adds t...

The role of livestock mobility in the livelihood strategies of rural peoples in semi-arid West Africa
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...

Changing uses of wealth stores by rural smallholders: Description of an approach used for longitudinal analysis of livestock transactions in the Sahel
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...

In this document ILCA proposes a set of six researchable issues pertaining to ILCA's three research areas that need to be investigated (three broad themes). A brief description of the researchable issues is presented. This includes economic and policy measures to improve the management of natural...

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...
