World Water Day, on 22 March every year, is about taking action to tackle the water crisis. Today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.

This year’s theme – Nature for Water – explores how we can use nature to overcome the water challenges of the 21st century. Find out more by visiting http://worldwaterday.org/
