Growing demand, shrinking suppliesExpanding, thirsty citiesThreatened ecosystemsIrrigation for food securityWater to generate powerAmenity value, recreation
Drought, early runoff Global & regional warming
Urban heat islandGroundwater depletion
Fewer (no?) “next buckets”
Adapt while mitigating climate & societal driversInterdisciplinary, 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
