Science Museum puts water scarcity in spotlight

A new exhibition dedicated to water conservation and its role in beating a global food crisis opens tomorrow at London's Science Museum.

Under the headline 'Water Wars: fight the food crisis', the exhibition will showcase five innovative projects from around the world, designed and developed to secure more water to grow food. These include a British initiative, the Seawater Greenhouse, which uses solar and wind power to evaporate fresh water from seawater.

Exhibition manager Sarah Richardson said: "Water scarcity is a big issue that's going to affect us all and we can't ignore it any longer. Many of us don't realise how much fresh water goes into growing our food - it takes 13 bath tubs for example, to make a normal-sized chocolate bar. So indirectly we use a lot of water from other countries since we import about 40% of our food from abroad. This exhibition gives the opportunity to see how engineers are working round the clock to invent ways for us to save water before it is too late."
