World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources. It is about taking action to tackle the global water crisis, in support of Sustainable Development Goal (SDG) 6: water and sanitation for all by 2030.
In 2025, World Water Day focuses on glacier preservation. UNESCO and the World Meteorological Organization are the UN lead agencies for the celebration.
Glaciers serve as natural freshwater reservoirs, releasing meltwater that supports drinking water supplies, agriculture, industry, and healthy ecosystems. They provide essential benefits such as climate regulation and protection from natural hazards.
Preserving glaciers is vital for the well-being of individuals and communities worldwide. Through the implementation of sustainable glacier management and monitoring practices, humanity can protect these frozen reservoirs that still hold approximately 70% of Earth's freshwater. Implementing sustainable management practices and fostering international scientific cooperation are vital steps in preserving these critical water sources, ensuring long-term prosperity and promoting global peace.
Glaciers play an essential role in the global water cycle, storing nearly two-thirds of all the freshwater on Earth - they are the water towers of the world.
