Water is such a basic human need that it takes real ingenuity to find new ways to control, retrieve, and share this critical resource. We meet some of the wizards of water—the engineers who are helping communities handle acute water challenges and plan for the future.

Contamination of China's fresh water resources from industrial pollution and inadequate sewage treatment is seen by Chinese residents as the nation's most critical environmental priority, according to a new public opinion survey. The survey by Circle of Blue, an American multi-media news and science organization, and GlobeScan, a global public opinion polling firm, also found that people are hungry for more information.

Scientists, led by Professor Martin Parry, the former co-chair of the Intergovernmental Panel on Climate Change, are set to warn that the UN negotiations aimed at combating climate change are based on unachievable low costs. The real costs are likely to be 2-3 times greater than estimates set out by the UN Framework Convention on Climate Change, according to a new report published by the International Institute for Environment and Development and the Grantham Institute for Climate Change at Imperial College London.

Grail Research has just released a study on water shortages across the world. Fresh water is becoming increasingly scarce, and in countries like India and China that are rapidly growing, the scarcity will hit hardest as the culture moves towards consumerism. The study's findings illustrate how current reserves must be managed more effectively if scarcity is to be mitigated, but at the current rate, an estimated 3 billion people will live below the water stress threshold by 2025.
