The triennial World Water Development Report (WWDR) is the United Nations System flagship report on water, a comprehensive review of the state of the world’s freshwater resources. The Reports provide a mechanism for monitoring changes in freshwater resources and their management and tracking progress towards achieving targets, particularly those of the Millennium Development Goals and the World Summit on Sustainable Development. The Reports also offer best practices and in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector. Co-ordinated by the World Water Assessment Programme (WWAP), the development of the WWDR is a joint effort of the 26 UN agencies and entities that make up UN-Water and is carried out in partnership with UN-Water Partners, governments, international organizations, non-governmental organizations and other stakeholders.
