Summary
Deforestation in the Cerrado, one of the world's most biodiverse savannas, has significantly altered regional climate and water availability. A study analyzing land-use transitions (LUTs) from 2006 to 2019 found that clearing forests for cropland or pasture increased land surface temperature (LST) by ~3.5°C and reduced evapotranspiration (ET) by up to 44%. These changes, driven by satellite data and regression analyses, have already caused a 10% reduction in water recycled to the atmosphere and a 0.9°C increase in LST compared to native vegetation. Future scenarios project that continued deforestation could further worsen these effects, while zero-deforestation policies could mitigate them.
