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.
World Water Day is celebrated annually on March 22 to raise awareness and inspire action to tackle the water and sanitation crisis. World Water Day became a UN observance day in 1993. A core focus of World Water Day is to support the achievement of Sustainable Development Goal 6: water and sanitation for all by 2030.
