This report presents a synthesis of studies conducted in the framework of the Cubango-Okavango River Basin Water Audit (CORBWA). This water audit is part of a larger project "Coping with water scarcity: the role of agriculture- Developing national water audits in Africa", which aims at providing countries with a comprehensive methodology for assessing, analysing and reporting of the use of scarce water resources. On the supply side, the audit provides information about the water availability. On the demand side, it gives a detailed picture, on how the water is used, for which purpose, and with which value. Africa uses around 85% of its withdrawn freshwater resources for agriculture. Therefore, a detailed assessment of agricultural water use, including its productivity, its value-in-use, and its efficiency during the water use process, gives the countries a better insight in how to adapt their water policy and how to improve their water management in future through strategic interventions to increase their capacity to cope with water scarcity. The CORBWA project, has taken advantage of the long-term involvement of the Food and Agriculture Organization of the United Nations (FAO) in support of the Permanent Okavango River Basin Water Commission (OKACOM) through the Environmental Protection and Sustainable Management of the Okavango River Basin (EPSMO) Project.
