Description :
This paper outlines a research project focusing on the environmental basis for sustainable development in the Sahelian zone of West Africa. It is demonstrated how a Geographical Information System (GIS) can be utilized for integrating environmental 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 of evapotranspiration and plant production.
