As part of our series of special features on water we're asking you to send us your pictures from around the world depicting the importance of the vital resource to your area.
China, India, Africa and the Middle East are all among key areas where access to water and irrigation are central to people's daily lives, as well as directly affecting the political landscape of the regions.
Do you live in an area where the supply of water is central to your daily life? Is access to water a major issue in your region?
Have you got a story with an accompanying picture to illustrate the importance of water to your locality?
If so, we would like to hear from you.
We will select the best of your pictures and publish them here and on our special water site.
How to submit a picture
