A wave of new research using decades of NASA satellite data has uncovered a dramatic and unprecedented loss of freshwater across Earth's continents.

Four massive 'mega-drying' regions have been identified, threatening water security for billions and putting food supplies at risk. Experts urge immediate action to manage water resources and address the escalating global water crisis.
