Water issues are about people, and ecosystems, and financial realities. They’re about climate and energy and old habits dying hard. Since really thorny water issues don’t have a single cause, the only way to make progress is to integrate all of those other pieces—people, energy, climate, economics—into the solution.

The United Nations World Water Development Report is UN-Water's flagship report on water and sanitation issues. It is launched around World Water Day each year and gives policy recommendations to decision-makers by offering best practices and in-depth analyses. The 2025 report is titled "Mountains and glaciers - Water towers." It highlights the urgent challenges posed by rapidly melting glaciers, threatening global water security, food and energy supplies, and environmental stability. As the climate warms, the resulting glacial retreat intensifies floods, droughts, landslides, and sea-level rise. The report emphasizes the need for immediate action to reduce carbon emissions and outlines strategies to adapt to these changes, stressing the vital role of mountain meltwater in achieving the Sustainable Development Goals.
