Water shortages are occurring in 1/3 of the planet’s watersheds and aquifers 1/2 of the world’s population is affected
3/4 of the world’s irrigated acreage is affected

Recipe for a sustainable water future1. Set sustainable limit on water
extractionsa) based on community visioningb) based on reliable water availabilityc) based on ecological needsd) hedge against climate change
2. Reduce consumption to sustainable level
3. Quantify rights to use available water
4. Enable trade among water rights holdersa) Water purchases by those that need/value it
mostb) Water purchases to restore freshwater
ecosystems c) Incentivizes water-saving
Allowable extraction
Reliable Water Supply
Existing level
Desired level

Big Solution #1:Create water
(each gallon we don’t consume is a gallon available for other users or
nature)
