Earth's continents are losing fresh water much faster than scientists thought, mostly because aquifer pumping in regions like northern India, southern Iran and parts of the U.S. is 45% more pronounced, on average, than previous estimates suggested, new research shows.
The study used satellite data to map freshwater trends across the globe between 2002 and 2025. Thanks to a high-resolution rendering method, researchers revealed regional gains and reductions in terrestrial water storage that were 33% more marked, on average, than in previous studies. The amount of fresh water lost was much higher than the gains overall, highlighting the urgent need for better water management to stave off a global water crisis.
