World Water Day 2025 will focus on the theme, ‘Glacier Preservation,’ to highlight the critical role of glaciers in sustaining life and the water cycle. Glaciers, mountain run-off, and snowmelt provide nearly two billion people with water for drinking, agriculture, and energy production. 

The Day aims to raise awareness on the challenges created by melting glaciers and calls on the global community to accelerate carbon emission reductions and implement local strategies to adapt to shrinking glaciers and uncertainties in water flows.
