In the Sahel of West Africa, the productivities of rangelands, croplands and livestock are inextricably linked. Cattle, sheep and goats graze rangelands and crop residues, and their manure/urine is used to fertilize crops. Rangelands provide important feeds during the manuring period, resulting i...

Plant density and tiller cunts were done in several Sahelian rangelands in Mali, under a variety of soil, rainfall and grazing situations. Numeric models were developed to explain the dynamic relationship between grass tillering and herb density. Tests of application of these models to the plant ...

Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of canopy cover can now be easily and precisely made through image processing of high-resolution digital photography. This study aims to determine rapid, accurate and non-destructive ecological measuremen...

Little of the current focus on landscape fragmentation has focused on rangelands or pastoral lands. This paper investigates the existing evidence for causes and processes of fragmentation in pastoral lands and its effects of landscapes and peoples. More conceptual work is needed on the definition...

A major challenge for contemporary conservation policies and practices is formulating workable compromises between wildlife conservation and the people who live with wildlife. We strongly support the view that anthropology has a critical role to play in contributing to our understanding of human-...

This study investigates development priorities of individuals living in 11 communities in the arid and semi-arid rangelands of northern Kenya and southern Ethiopia. We first asked individuals to describe development efforts that have been implemented in their community. People were then asked to ...
