Rural areas of West Africa have seen notable transformations these last two decades, mainly due to high population growth, development policies in favor of export crops and introduction of new cropping practices. The results of these developments are a pressure on forestry resources, an evolution of farming systems, a depletion of soils and a saturation of cultivated areas.

In that context, early warning systems have been developed in order to foresee and curb food insecurity by the mean of hazard analyses.The present work deals with agrarian changes and their mechanisms, in the context of early warning sys...
