Description
Augusto Getirana and co-authors reconstruct in 2026 how Brazil's groundwater storage changed over two decades of human use and climate stress. Brazil holds the world's largest renewable fresh water reserves, yet repeated national water crises expose growing strain. The team merged satellite and ground data inside an artificial intelligence framework to map groundwater behavior nationwide.
Average recharge in exposed aquifer zones from 2002 to 2023 came to roughly twelve percent of rainfall in those areas. Heavily pumped aquifers in eastern Brazil showed lasting depletion or no recharge, worsened by long droughts and climate swings. Their decline mirrors patterns in intensively farmed regions of Asia and North America. The findings matter for a country central to world food supply.
