Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., suggests that the reduced flows in many cases are associated with climate change, and could potentially threaten future supplies of food and water.
The Colorado River in the southwestern United States and northwestern Mexico, the Yellow River in northern China, the Ganges in India and the Niger in West Africa are losing water, says the study.
The study examined stream flow in 925 of Earth's largest rivers, and found significant change in about one third of them over the past 50 years. These rivers, all key sources of water for the regions they flow through, were found to be funneling less water through their channels.
