The United Nations World Water Development Report 2025

"Water flows from top to bottom, but food insecurity goes from bottom to top. The earth's mountains provide 60% of freshwater, but the communities that safeguard these vital resources are among those who suffer the most from food insecurity. We must invest in their resilience to protect glaciers, rivers, and a shared future for all of us". The United Nations World Water Development Report 2025, published by UNESCO on behalf of UN-Water, reveals how climate disruption, biodiversity loss and unsustainable activities are transforming mountain environments at an unprecedented rate and threatening the water resources on which billions of people depend. There is now an urgent need for international cooperation, adaptation strategies and actions to address the crisis that looms over our mountains and glaciers.
