Nuclear and isotopic techniques play a vital role in water irrigation in places with extreme dry conditions

Incredible!!! nuclear and isotopic techniques play a vital role in water irrigation in places with extreme dry conditions!!! "Agriculture is the largest global consumer of water -- accounting for around 70% of the freshwater drawn from lakes, waterways and aquifers around the world.
The IAEA is operating projects in Kenya that use nuclear and isotopic techniques to inform farmers how to use their scarce water resources efficiently for both rain fed and irrigated agriculture.
One project is supporting the use of "drip irrigation" a cost-effective technique that can reduce water use by 50 per cent, compared to other forms of irrigation. A Maasai community on the Tanzanian border is also benefiting from the IAEA project which is helping them to grow healthy crops using very little water in extreme dry conditions." see the full video: http://www.youtube.com/watch?v=vbaTz8TO55E&feature=relmfu

... also check out this video related to the use of nuclear techniques in locating safe sources of water... "In 1993, Bangladesh found its main source of fresh water was contaminated with natural arsenic, resulting in a public health threat impacting millions of people. In cooperation with the World Bank, the IAEA used isotope hydrology techniques to help the country to find safe drinking water. By using nuclear techniques, Bangladesh was able to demonstrate that isotope hydrology could effectively and affordably help to locate identify safe sources of water. This film demonstrates some of the effects of arsenic poisoning in these villages and its successful resolution." http://www.youtube.com/watch?v=grPbrDVJrXc&feature=feedu
