- 2. Global Issues • Waterand sanitation for billions • Agriculture uses vast quantities of water • Large scale water transfers • Small farm rely food production using Irrigation • Reclamation projects have great influence • Irrigation return flow affects WQ • Farm and city cooperation is possible • Farm policy and water policy are linked
- 3. Understanding Nexus • Whereand how these three systems interconnect? • Water and energy: produce food for billions • Energy used for moving water, and clean up the water and sending down the drain • Water is required to run power plants and to produce oil, gas and coal • Some food crops are turned into fuel for vehicles
- 4. U.S. Status: Water,Energy, and Food Example: • Water nourishes corn • Corn is used for ethanol and food • Ethanol competes with food for corn • Policy to promote ethanol impacts food, energy, and water
- 5. Food Water Energy Natural systems + Infrastructure Society Economy Health Prosperity • Natural systemsplus infrastructure provide water • Water is essential for food and energy production • Food, energy and water nourish society and the environment • Food, energy and water create health and prosperity • Food and energy impact water and natural systems Nexus: System Interactions

Sustainable Solution • Multi-disciplinary/multi-throngedand stakeholder driven • Need of new generation of educators, researchers and innovators • An innovative and collaborative platform for developing technologies, sharing knowledge and data for adoption of best practices and methods : Co-Design-Co-Create and Co- Implement and Co-Assess the impact • Optimize water use, intensive sustainable food production (climate smart seeds, ag inputs), and efficient energy use Bottom line…. protecting planet and limited natural resources is key otherwise Homo Sapiens extinction is looming around corner!
