Abstract
What is the nexus?
  • Water, energy and food (WEF) – essential for quality of life
  • WEF mutually interdependent, for example:
    • Irrigation – key for food security
    • Hydropower – for energy security
    • Sustainable farms and cities – water security
    • Resource nexus – crucial for societal well-being and prosperity
  • Social & political processes + institutions & policies - regulate & manage resources
  • Security – seen in human, environmental terms and national security terms
