Groundwater overuse puts Brazil’s river flow at risk, study finds

In many parts of Brazil, rivers may be losing water to the ground instead of gaining from it. A recent study found that groundwater levels in several regions are lower than those of nearby rivers, pulling river water underground. This shift, potentially driven in part by intensive pumping of groundwater, could reduce streamflow and have serious consequences for Brazil’s water supply, agriculture, energy production, and ecosystems. While the stud…
