The biggest victim of the great California water crisis isn't cities or farmers

LOS ANGELES — As California fast approaches what is likely to be a fourth year of punishing drought, residents are being asked to cut their water use to historic lows. But while city dwellers are rising to the occasion — including record reductions in Los Angeles in August — urban consumption still represents only a small fraction of total water use in the state.

Where the rest of it goes depends on whom you ask. The California Department of Water Resources says 50% of the state's water goes toward environmental purposes, 40% toward agriculture and 10% toward urban areas.

But experts say that calculation tells only part of the story, especially because the environment's share tends to shrink dramatically during dry years. Instead, a clearer picture begins to emerge when you consider water designated for domestic and business use. Of that, 80% goes toward agriculture and 20% toward urban areas.

While agriculture's share may seem outsize to some urban residents being asked to , experts say the sector is also dealing with cuts, shortages and shifts brought on by drought and climate change, even as it continues to play a major role
