Water – 80% to 90% of Global Freshwater Used for Irrigation; Sustainable?

Excerpted from one of my favorite tumblrs, alextiller:

As farmers around the world are forced to pay more for water, governments and land-use planners are likely to have to shift their priorities for land use, including greater use of naturally-watered land for agriculture. It is unlikely that we are going to see many governments tearing down housing developments in order to return the land to agricultural use, but over time the market will make it economically rational to farm where the water is.
