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 ...

Turner, M.Ayantunde, Augustine A.Patterson, E.D.Patterson, K.P.[Conflict management for improved livestock productivity and sustainable natural resource use in Niger]Conflict management for improved livestock productivity and sustainable natural resource use in Niger

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...

This paper reports on a four-site study conducted in the Sahelian zone of Niger. The study takes a novel mixed methods approach for understanding conflict management from the perspective of rural peoples by not only describing past highly publicized conflicts but also by analyzing the steps rural...

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...

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...

Growing pearl millet and cowpea in combination with raising ruminant livestock is widely practiced in the Sahel. In this farming system, livestock feeding depends mostly on rangeland, fallows and cropland grazing. Nutritional constraints to grazing ruminants stem primarily from feed scarcity and ...

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...
