The Country Water Assessment (CWA) evaluates the balance between reliable and available water supplies and future demands for sustainable economic development in Indonesia. Articulated around the water,food, and energy nexus, the CWA explores technical, institutional, and policy options to improve planning, management, and development of water resources. The 2015-2019 midterm government development policy guides the priorities covered under the CWA. This assessment intends to provide a platform for dialogue to advance water reforms across Indonesia, focusing on Java, Sumatera, and Sulawesi—-the country's three main economic regions.
