“Nearly one in 10 watersheds in the United States is “stressed,” with demand for water exceeding natural supply — a trend that appears likely to become the new normal, according to a recent study.
“By midcentury, we expect to see less reliable surface water supplies in several regions of the United States,” said Kristen Averyt, associate director for science at the Cooperative Institute for Research in Environmental Sciences at the University of Colorado-Boulder and one of the authors of the study. “This is likely to create growing challenges for agriculture, electrical suppliers and municipalities, as there may be more demand for water and less to go around.”
According to the research of Averyt and her colleagues, 193 of the 2,103 watersheds examined are already stressed — meaning demand for water is higher than natural supply. The researchers found that most of the water stress is in the Western United States, where there are fewer surface water resources, compared with the East.”
