The USA's space agency NASA has confirmed that human activity is acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend for a massive redistribution of freshwater across Earth. It said the acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend is continuing as populations acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend and demand for food increases. In particular, acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend regions were drying, while tropical acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend and higher latitudes were gaining water supplies. NASA warned that if this acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend continued, many highly populated urban areas could struggle to find acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend water in the future. NASA's claims are the acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend of a 14-year study into shifting locations and depleting resources of freshwater. It was acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend of a mission conducted between 2002-2016 called GRACE, which is an acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend for Gravity Recovery and Climate Experiment. Researchers say that the shifting freshwater acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend are the acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend 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 acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend altered the global water landscape in a very acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend way." He warned that: "The human fingerprint is all over changing freshwater acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend . We see it in large-scale overuse of groundwater. We see it as a driver of climate change." Professor Famiglietti said at acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend 40 per cent of the 34 hot areas examined in the research were acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend than two decades ago acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend of human activity, especially acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend groundwater pumping for acronym areas availability because drastically drier equatorial excessive farming least part patterns profound redistribution responsible result shift sufficient trend .
