This article discusses a study that has shown how deforestation is causing water problems. The study has produced solid estimates of the hydrologic benefits of forest restoration work. Scientist Roger Bales explains how this could create a new method to finance controlled burns and selective logging.
A team of scientists from the University of California and the National Park Service now has some answers. In a new study, they combined sensors that measure evapotranspiration – how much water trees exhale – with satellite images of “greenness” on the landscape to estimate the additional freshwater runoff that could be created by thinning overgrown forests.
