Climate change is going to be the focus of the Eden Project's new biome, with a teaser exhibit soon to open for the summer running from 26 May to 2 September 2007. WaterAid has an important part to play within the new exhibit called Towards the Edge.

International charity WaterAid is working to provide clean, safe water to the world's poorest people - over one billion of whom are already struggling to survive on just 10 litres of water a day. With climate change threatening to affect these people the most, WaterAid is striving to provide long-term, sustainable water solutions.

One of the major issues facing us all in the near future is the challenge of ensuring that everyone has enough water. We need it to drink, to wash in, cook with, bathe in and grow crops with. In the UK, we are beginning to feel a few of the effects of climate change, but for the world's poorest people, a lack of water is already critical.

Justine Quinn, Eden's Public Education Manager explains: "The context for the new building will be the oncoming water crisis, the challenges in the supply of energy, and the impacts of these change to our climate. But it is not a building about climate change; it is a building because of climate change."

WaterAid's area in the exhibit will be highly interactive, making the charity's activities come alive. The charity has teemed up with Digit, the London based digital design agency, to create the Water Shed' installation. By using what looks like an ordinary garden hose to water the shed's wall, digital images and messages grow highlighting global water issues.

Tamsin Maunder from WaterAid says: "The Eden project highlights environmental issues in an engaging and inspiring way, giving WaterAid the perfect opportunity to raise awareness of the problems that face millions of people who have to live without safe water or sanitation. The Water Shed fits perfectly here - it looks like a simple shed but when messages start growing in the shape of trees it is completely captivating."

Visitors to WaterAid's area can also operate a handpump for themselves, seeing how the simplest technology is often the best solution. Plus they can log onto WaterAid's website, read some real life stories about how provision of safe water can literally transform people's lives, and also they can find out lots of different ways that they can help make a difference.

Towards the Edge is running at the Eden project from 26 May to September 2007.
