The 2015 edition of the United Nations World Water Development Report (WWDR 2015), titled 'Water for a Sustainable World' was launched at the official celebration of the World Water Day, on March 20, in New Delhi, India.

The WWDR 2015 demonstrates how water resources and services are essential to achieving global sustainability. Taking account of economic growth, social equity and environmental sustainability, the report's forward-looking narrative describes how major challenges and change factors in the modern world will affect – and can be affected by – water resources, services and related benefits.

The report provides a comprehensive overview of major and emerging trends from around the world, with examples of how some of the trend-related challenges have been addressed, their implications for policy-makers, and further actions that can be taken by stakeholders and the international community.

The report can be downloaded from the UNESCO website.
