What to know about Brazilian breadbasket's aquifers are falling, and new satellite maps show where water stress is growing

A collaboration between NASA and Brazilian researchers used AI and satellite data to map groundwater changes in Brazil from 2002 to 2023. The study found significant aquifer depletion in central and eastern regions, attributed to a combination of climate factors and human activities such as agriculture and mining.

What happened

Brazilian breadbasket's aquifers are falling, and new satellite maps show where water stress is growing Gaby Clark Scientific Editor Robert Egan Associate Editor A collaboration of scientists from NASA and Brazilian research institutions has produced a…

Why it matters

The images reveal significant declines in some of the aquifers that are critical to one of the world's largest agricultural producers.

Common ground

In the study, published June 3 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.

Perspective signals
