Adapting to water scarcity and changing climate Christopher Scott Udall Center for Studies in Public Policy, and Dept. of Geography & Regional Development
Growing demand, shrinking supplies Expanding, thirsty cities Threatened ecosystems Irrigation for food security Water to generate power Amenity value, recreation Drought, early runoff Global & regional warming Urban heat island Groundwater depletion Fewer (no?) “next buckets”
Adapt while mitigating climate & societal drivers Interdisciplinary, applied research on: Agriculture – urban water transfers: potential & limits Urban heat island: landscaping water demand & cooling Water reuse, greywater, water harvesting: public choice, regulation, and technology Water-energy nexus: adaptation vs. mitigation tradeoffs Transboundary waters: US-Mexico & global partnerships Partners: NOAA, USGS, ASU, NGOs, researchers and agencies in Mexico, India, Ghana, and Ethiopia Christopher Scott
