  1. Adapting to water scarcity and changing climate Presented at University of Arizona Environmental Summit, 22 April 2009.

  2. Adapting to water scarcity and changing climate Christopher Scott Udall Center for Studies in Public Policy, and Dept. of Geography & Regional Development udallcenter.arizona.edu/wrpg cascott@email.arizona.edu http://www.stormeffects.com

  3. 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”

  4. 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 udallcenter.arizona.edu/wrpg cascott@email.arizona.edu
