Two examples towards the efficient and sustainable management of scarce water resources in North-west and West Africa:
In the IMPETUS project thorough investigations of all aspects of the hydrological cycle are carried out within two river catchments in West Africa: the wadi Drâa in the south east of Morocco and the Ouémé river in Benin. This choice is motivated by the indications found that since the 1970s the droughts north and south the Sahara have been related.
In order to solve possible future problems with regard to freshwater supply, a clearly interdisciplinary approach is taken. The underlying method is demonstrated exemplarily on the basis of two pressing problem clusters.
