CERA project information for GLOWA-IMPETUS (BMBF)

GLOWA-IMPETUS (BMBF): Within IMPETUS, the different components of the hydrological cycle and their interactions are investigated with an interdisciplinary approach in two river catchments in West Africa: the Oueme River in Benin and the Wadi Draa in the South-East of Morocco. The subprojects consider the atmospheric variability, the continental hydrosphere, and the important processes regarding land use and land cover. Moreover, the influence of the socio-economical development and cultural as well as medical situation on the availability of drinking water is examined. A series of numerical and conceptual models of the individual components of the hydrological cycle were adapted.
A measurement network of necessary parameters was set up in data sparse areas. To solve the relevant problems concerning complex issues such as water availability, climate change, land use, food security or demographic development, the models are being coupled by means of data exchange and integrated in plausible scenarios.
The objective consists of describing possible ways of future development, as well as their causes and their interactions. It will build up the foundation allowing to develop strategies for local decision makers.
