  1. Water Supply and Demand Bangkok 2013

  2. Water Supply

  3. Measuring Supply • Water is expensive to move from watershed to watershed • Heavy so costly to move • Low valued (except for drinking water) • Correct measure of supply is at watershed level- not country level • Monthly pattern also matters • Expensive to store across months • Requires a dam

  4. Measuring Water Supply • Care about fresh water (not saltwater) • Care about supply relative to land and people • Not every country the same • Some have abundant water • Some have very little • Some have scarce water/land but abundant water/person

  5. Water Supply

  6. Measuring Demand • Four primary users • Agriculture- largest user • Industry- second largest • Residential- highest valued

  7. Water Demand

  8. Water Allocation • Suppose two users: farmers and U&I • U&I more price inelastic than farmer • Suppose that farmers have more water than efficient amount • What is loss?

  9. Initial Allocation U & I Supply Price Inefficiency Farmer Water for farmers Water for Urban/Industry

  10. Climate Change • Suppose that climate change reduces water supply • Suppose farmer water is protected • Water must come from U&I • Efficiency loss grows

  11. U&I Supply Price Farmer Water for farmers Water for Urban/Industry

  12. Climate Change • Suppose that climate change reduces water supply • Suppose water is reallocated from farmers to U&I • Efficiency losses shrink • Water management objective- equate marginal value of water across users

  13. U&I Supply Price Farmer Water for farmers Water for Urban/Industry
