The Middle East and North Africa Water Center Network (MENA WCN) will link technical institutions across the region to work together and with outside counterpart institutions on critical water challenges. The Network will strive to foster partnerships; build and exchange regional science and technology capacity to improve water resources planning and management; and develop and disseminate policy tools and technical and management interventions that expand water supply, manage demand, and dramatically increase its efficient and productive use. A network of cooperating institutions will facilitate collaborative activities, including competitive grants programs, capacity building, institutional twinnings, exchanges, fellowships, and knowledge management.
