Drip irrigation could help save world water resources
Better techniques such as drip irrigation could reduce water use by 25%-90%
if exported to the developing world. Irrigation of crops accounts for 90% of the
worlds use of fresh water.
Leaders attending the Earth Summit II in New York are being warned that wars
over the worlds dwindling water resources are likely in the next 10 years
unless urgent action is taken to improve conservation technologies in developing
Up to 800 rivers could increasingly become the focus of international
disputes. These include the Amazon, Euphrates and Danube. This could happen as
countries along their lengths pump out more water to irrigate crops and supply
growing industries and rising populations. The alarm is raised in a UN report
Comprehensive Assessment of Freshwater Resources of the World.
