  • Secret contracts, unusual rises of water

prices

  • Group of activists reached publication of

Discussion

  • Why is green virtual water better than blue virtual water?
  • When might use of green virtual water be a problem?
  • What are the limits by comparing water flows between

countries (c.f. Brazil, US)?
