GLOWA-Volta

 

 GLOWA Volta Project - Phase III

Sustainable water use under changing land use patterns, rainfall reliability and water demand in the Volta basin.

The project is financed by the Federal Ministry for Education and Research. Additional funding comes from the Ministry od Science and Research of North Rhine-Estphalia. 

 

The overall objective of the GLOWA Volta Project is the analysis of the physical and socio-economic determinants of the hydrological cycle inthe face of global climate change. Based on this, the project aims at the establishment of a scientifically sound Decision Support System for water resource management.
