The use of satellite imagery in rangeland management: a comparative analysis of three Sahelian zones

Among the most vulnerable environments in Africa are the rangelands of the Sahel. This study compiles a sequential database designed to clarify how Sahelian rangelands are changing and in response to what factors. Also reviewed are common theories about how rangelands are affected by drought, for example by use of misguided methods of farming. The most important policy recommendation on rangelands is that governments advocate and plan for public participation in solving the problem. In addition, governments should foster monitoring and analysis procedures which are national in scope compatible with global approaches.
