information on landforms, vegetation density and water-balance. The environmental information was collected during the HAPEX-Sahel-Experiment in Niger, August-October 1992. The aim of this paper is to demonstrate and discuss parameterization of the processes
The aim of the project is to develop a method for mapping and monitoring of biological diversity in the Sahel zone. Sahel is undergoing marked environmental changes, affecting not only human populations but also ecological communities. These ongoing
