Freshwater sustainability challenges shared by southwest and southeast US

Terra Daily: Water scarcity in the western U.S. has long been an issue of concern. Now, a team of researchers studying freshwater sustainability in the U.S. have found that the Southeast, with the exception of Florida, does not have enough water capacity to meet its own needs.
Twenty-five years ago, environmentalist Marc Reisner published Cadillac Desert: The American West and Its Disappearing Water, which predicted that water resources in the West would be unable to support the growing demand of cities, agriculture and industry.

A paper co-authored by a University of Georgia researcher and just published in a special issue of the journal Proceedings of the National Academy of Sciences offers new support for most of Reisner's conclusions, using data and methods unavailable to him in 1986.

Although the paper focuses on freshwater sustainability in the Southwest, co-authors Tushar Sinha, a postdoctoral scientist at North Carolina State University; John Kominoski, a postdoctoral associate at the UGA Odum School of Ecology; and William Graf, a professor of geography at the University of South Carolina, said that the findings have important implications for the Southeast as well. "It turns out that the Southeast has a relatively low capacity for water storage," said Graf….
