California officials crafting a new conservation plan for the state’s dry future drew criticism from environmentalists on Thursday for failing to require more cutbacks of farmers, who use 80 percent of the water consumed by people. Gov. Jerry Brown ordered up the state plans for improving long-term conservation in May, when he lifted a statewide mandate put in place at the height of California’s drought for 25-percent water conservation by cities and towns. Ben Chou, a water-policy analyst with the Natural Resources Defense Council, criticized state planners for not mandating any new water-savings by farm water districts.
