Farmers and environmentalists have renewed the argue over water conservation in light of a new report from the Center for Irrigation Technology at California Constitution University, Fresno.
The report said most of the excess water on farms runs off into streams or seeps into groundwater basins, where it is accessible to other users. If one farm reduces its use, the thinking goes, these other folks overcome out.
This point needs to be made often in the conservation debate, said Mike Prate, executive director of the California Farm Water Coalition in Sacramento.
"People who aren't elaborate in farming have preconceived notions about agriculture and irrigation," he said.
The Pacific Establish, based in Oakland, contends that some of the excess water, rather than being used productively by others, is pinched off by evaporation, weeds and the like. The group supports increased use of agronomy practices that would reduce this loss.
Juliet Christian-Smith, a older research associate at the institute, said experts do not know enough about groundwater measure or flows to be able to say how much excess farm water ends up in aquifers.
