The USA's space agency NASA has confirmed that human activity is for a massive redistribution of freshwater across Earth. It said the is continuing as populations and demand for food increases. In particular, regions were drying, while tropical and higher latitudes were gaining water supplies. NASA warned that if this continued, many highly populated urban areas could struggle to find water in the future. NASA's claims are the of a 14-year study into shifting locations and depleting resources of freshwater. It was of a mission conducted between 2002-2016 called GRACE, which is an for Gravity Recovery and Climate Experiment.

Researchers say that the shifting freshwater are the of human activity. Jay Famiglietti, a co-author of the research and the Senior Water Scientist at NASA's Jet Propulsion Laboratory, said: "The study shows that humans have really altered the global water landscape in a very way." He warned that: "The human fingerprint is all over changing freshwater . We see it in large-scale overuse of groundwater. We see it as a driver of climate change." Professor Famiglietti said at 40 per cent of the 34 hot areas examined in the research were than two decades ago of human activity, especially groundwater pumping for .
