  7. Global Consumptive Use of Water Households Industry km3/year Livestock Irrigation

  8. Water-Energy-Food-Materials Nexus “When we try to pick out anything by itself, we find it hitched to everything else in the Universe” -- John Muir

  9. Food Depends on Water • Food is a major cause of runoff that results in algal growth www.waterfootprint.org

  10. Energy Depends on Water • Energy sources affect water quality through acidification and runoff www.waterfootprint.org

  11. Water Depends on Energy Gleick, P. H., Cooley, H. S., Env. Res. Let., 2009

  12. Solutions • Consumption side • Use water more efficiently • Consider direct and indirect use – reduce water footprint • Production side • Enhance the availability of good quality fresh water • Harvest rainwater, reduce runoff • Restore wetlands • Plant native vegetation • Also benefits energy, food, materials, and the environment

  13. Address the Paradox • Diamonds • Highly valued in terms of money • Not essential • Water • Very low value in monetary terms • Essential for life • Address social, political, cultural challenges
