This policy brief for the Gedaref-Adigrat Transboundary Aquifer resonates the outcomes of a Shared Aquifer Diagnostic Analysis (SADA) and the Groundwater Modelling, assignments conducted as part of a groundwater project executed by the Nile Basin Initiative. SADA provides a regional overview of aquifer characteristics and water resources management, supported by a thorough stakeholders’ survey. While presently only a fraction of population in the aquifer area has access to clean and safe water, the population grow, intensive agriculture and lack of sanitation are causing ever-increasing groundwater depletion and pollution. Better groundwater monitoring is essential for improvement of knowledge about the aquifer and its management. Better cooperation at all levels of governance, nationally and internationally, is necessary to
ensure integrated and harmonized management of water resources in the region.
