A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical to one of the world's largest agricultural producers.
In the study, published in Science Advances, researchers used artificial intelligence to combine satellite observations, well measurements, geology, and water-use data to evaluate groundwater in Brazil from 2002 to 2023. They found that multiple factors, including drought, deforestation, agriculture, mining, and increasing groundwater extraction, are straining aquifers that provide more than half of Brazil's water.
