To address issues of integrated water management of large watersheds in the face of global change, the German Federal Ministry for Science and Education has initiated a large program under the name "GLOWA". GLOWA comprises five research projects along a gradient from North Germany to West Africa. The GLOWA Volta Project concerns itself with the analysis of the water cycle in the Volta Basin and the subsequent development of a decision support system. The research team consists of meteorologists, hydrologists, agronomists, geographers, economists, and institutional analysts. Integration of the research outcomes from all these disciplines into one quantitative basin model is the main scientific challenge of the project.
