All reports

The report is published by UNESCO, on behalf of UN-Water and its production is coordinated by the UNESCO World Water Assessment Programme.

The report gives insight on main trends concerning the state, use and management of freshwater and sanitation, based on work done by the Members and Partners of UN-Water.

Launched in conjunction with World Water Day, the report provides decision-makers with knowledge and tools to formulate and implement sustainable water policies. It also offers best practices and in-depth analyses to stimulate ideas and actions for better stewardship in the water sector and beyond.

The WWDR was founded in response to a call from the UN Commission on Sustainable Development (CSD) to produce a UN system-wide periodic global overview of the status (quantity and quality), use and management of freshwater resources.
The report gives insight on main trends concerning the state, use and management of freshwater and sanitation, based on work done by the Members and Partners of UN-Water.

Until 2012, the WWDR was produced and released every three years. In 2012, as a result of a Global Stakeholder Survey in which stakeholders called for change in terms of focus and periodicity, UN-Water Members decided to change the WWDR into an annual production with a thematic focus on specific strategic water issues.
