During the 2012 Stockholm World Water Week session entitled "Stockholm Water Prize Laureates Seminar in the Presence and Honour of H.M. King Carl XVI Gustaf: Food for Billions - The Need for a Holistic View", I took advantage of the opportunity to ask the panel of high level scientists, business people, and thinkers the following question.
"There has been a lot of discussion about how food production systems operate in a distorted market. Several people have pointed out that the market needs to allocate food more efficiently and to reduce waste, but cannot do so without a signal of the scarcity of its most valuable input - water. Acknowledging that it will inevitably be a challenge from the human rights dimension, should irrigation water be priced at a nontrivial amount to help manage water, yes or no AND why?"
This answer is from Professor Emerita Rita Colwell, University of Maryland.
