WASHINGTON (Reuters) - Rivers in some of the world's most populated regions are losing water, many because of climate change, researchers reported on Tuesday.
Affected rivers include the Yellow River in northern China, the Ganges in India, the Niger in West Africa, and the Colorado in the southwestern United States.
When added to the effects from damming, irrigation and other water use, these changes could add up to a threat to future supplies of food and water, the researchers reported in the American Meteorological Society's Journal of Climate.
"Reduced runoff is increasing the pressure on freshwater resources in much of the world, especially with more demand for water as population increases," Aiguo Dai of the National Center for Atmospheric Research in Boulder, Colorado, who led the study, said in a statement.
"Freshwater being a vital resource, the downward trends are a great concern."
You can live without oil. You will die without water. It is going to be an interesting couple of decades.
