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
