Growing with less

Water crunch turns eyes to agriculture's 85% share


Denver Post

Agriculture continues to use 85 percent of total water supplies. But growing numbers of farmers are shifting toward greater efficiency, replacing ditch-and-flood irrigation with center-pivot sprinklers and tubes that emit tiny drops. Colorado officials are counting on such increased efficiency and conservation as the state readies for an increase in people and industry — with a projected annual shortfall of 163 billion gallons.

In the virtual worlds of climate modeling, forests and other vegetation are assumed to bounce back quickly from extreme drought. But that assumption is far off the mark, according to a new study of drought impacts worldwide. Living trees took an average of two to four years to recover and resume normal growth rates after droughts ended, researchers report in the journal Science.
