Researchers warned that global warming threatens the water supply for urban communities in Arizona, in a new report funded by the Department of Commerce.
"Rapid growth in these areas has increased the vulnerability of urban water users to climatic changes," the University of Arizona researchers, who collaborated with Mexican researchers at El Colegio de Sonora, reported today. UA News explained that "researchers found increased vulnerability of urban water users to climatic changes because of factors such as aging or inadequate water-delivery infrastructure, over-allocation of water resources within the region and the location of poor neighborhoods in flood-prone areas or other areas at risk."
The reserachers proposed solutions tailored to various areas. For Tucson, Ariz., for instance, they suggested "long-term water supply/climate scenario" and "conservation promotion at household scale."
