Degradation of arid and semi-arid lands (ASALs) through denudation has been found to result in lowered capacity to support livestock, particularly under extensive production systems. After a participatory rural appraisal (PRA) in Kajiado district, an opportunity was identified in the pastoral res...

This paper explores the potential for, and limits to, sustainable agricultural growth in semi-arid Africa, with a focus on the role of pastoralism. Examines the main pressures on pastoral systems, and on the resource base upon which these depend. The paper argues that it is premature to contempla...

Temporal and spatial variabilities in rainfall, herbaceous production and biomass were studied over a 4-year period in a topographically diverse, arid pastoral region of northwest Kenya. A significant relation between rainfall and primary production was found, and this was applied in a manner tha...
