The study looked at how valuable water is in a Mexican irrigation district during droughts. Researchers used a special math method that figures out how to use water efficiently. They found that the actual value of water is higher than what users pay right now. The study shows that creating a water market could help manage water shortages during dry times. By trading water between different areas and changing crops, the district could deal with less water without losing too much money. This plan could work if all parts of the district can share water efficiently. It could lead to a fairer water price policy and better use of water.
