This paper presents main findings of a feasibility study for a joint transdisciplinary project to strengthen the implementation of integrated water resources management (IWRM) in the Cuvelai Basin, northern Namibia. The region is characterised by seasonal alterations of droughts and heavy rainfall, mostly saline groundwater and a lack of permanent rivers. Difficult local conditions pose a great challenge for water supply against the background of high population density. Currently, most drinking water of the area is withdrawn from the Kunene River at the Angolan border and transported through a canal and pipeline scheme. However, it is expected that this infrastructure will be put at risk due to increasing water demand on both the Namibian and Angolan side.
