Some environmentalists are motivated by news of world water woes; others are more moved by the scary numbers on their water utility bill. Both types can put their energy to good use on World Water Day 2011 on March 22. This year, the theme for the day’s “Water for Cities” — which means you can participate in solving the world’s water issues simply by taking efforts to save water in your urban home.

Celebrated annually since 1993, World Water Day’s organized by the UN Water group, which will hold its main event in Cape Town this year. But the day can be celebrated everywhere at events are happening around the world. Find a green-and-blue get-together near you on the UN’s official World Water Day 2011 website.

You can celebrate the day online too. Surfrider Foundation, for example, is focusing on saving water with a World Water Day photo challenge. Simply upload a photo of yourself holding up a sign with your water-saving tip to Surfrider’s Flickr Group. If your photo’s selected as one of Surfrider’s favorites, you’ll get a pair of Levi’s Water Less jeans.

Surfrider’s also put together a list of 15 water-saving tips. Most MNN readers will have implemented many of them, but perhaps World Water Day can be your chance to start working on the more challenging tips — like replanting your lawn or yard with climate adapted plants. What will you be doing on World Water Day?
