Effects of rainfall, wild herbivores and change in land use. Investigations with local populations and empirical observations showed a rapid degradation of the vegetation related to human activities.

We aimed to study the relationships between the recent changes in human activities and the level of vegetation resource so as to anticipate a possible lack of resources in an arid region confronted to recurrent droughts.
