To Solve California’s Water Crisis, We Must Change the Nation’s Food System
Posted on Mar 19, 2015
The bold headline of a recent Los Angeles Times editorial by the hydrologist Jay Famiglietti starkly warned: “California has about one year of water left. Will you ration now?” The write-up quickly made the social media rounds, prompting both panic and the usual blame game: It’s because of the meat eaters or the vegan almond-milk drinkers or the bottled-water guzzlers or the Southern California lawn soakers.
California’s water loss has been terrifying. But people everywhere should be scared, not just Californians, because this story goes far beyond state lines. It is a story of global climate change and industrial agriculture. It is also a saga that began many decades ago—with the early water wars of the 1930s immortalized in the 1974 Roman Polanski film “Chinatown.”
When my family first moved to the Los Angeles area, we spent years adjusting our lifestyle to be more in line with our values. Ten years ago, we stopped watering our lawn and eventually replaced the lawn with plants that were drought-tolerant or native to California. Three years ago, we installed solar panels on our roofs. Last year, we diverted our laundry runoff to our vegetable garden and fruit trees through a graywater system. We have replaced all our toilets with dual-flush systems to take advantage of local rebates, and we practice responsible flushing. We almost never wash our cars, and we shower less often in the winter. We are investigating rainwater barrels in our latest effort to be responsible stewards of our water. Yet none of our efforts to be an example to others have done anything other than make us feel morally self-righteous enough to wag our fingers at water wasters.

Even though Gov. Jerry Brown just imposed a series of mandatory water-conservation measures in response to the emergency, most of those measures are aimed at individual users and restaurants. While it is crucial for residents to stop wasting water on the utterly useless tasks of car washing and lawn watering, “residential use in California is about 4 percent,” Redman told me. “Eighty percent is for agriculture.”
The truth is that California’s Central Valley, which is where the vast majority of the state’s farming businesses are located, is a desert. That desert is irrigated with enough precious water to artificially sustain the growing of one-third of the nation’s fruits and vegetables, a $40 billion industry.
Think about it. A third of all produce in the United States is grown in a desert in a state that has almost no water left. That produce is trucked from the West Coast all over the country in fossil-fuel-consuming vehicles, thereby contributing to the very mechanism of climate change that is likely to be driving California’s historic drought.
“It is not a place that agriculture, at the scale and at the scope that exists now, should exist,” Redman explained.
The food journalist Mark Bittman, writing in The New York Times in 2012, summed up the dire situation in California’s Central Valley: “For the last century or so, we’ve been exploiting—almost without limitation—its water, mineral resources, land, air, people and animals.”
When water allocations from the federal government were cut, Central Valley farmers began drilling deep into the ground to pump water out of the state’s precious, ancient aquifer. Now, the pumping has gotten so out of control that water is being tapped faster than it can be replenished by rain or snowfall, leading to some parts of the land literally sinking. What’s worse, California’s farmers are irrigating their lands with water from a 20,000-year-old reserve, depleting and probably permanently damaging a reservoir that formed in the Pleistocene epoch.
Shockingly, until recently, California did not even regulate groundwater use, unlike states like Texas. Anyone could drill a well on their property and simply take as much water as they needed for their own use—a practice that dated back to the Gold Rush.
Then, last year, the state finally passed the Sustainable Groundwater Management Act, aimed at regulating water use from the aquifer and other ground resources. But the law is weak: It allows local water agencies to regulate and manage groundwater pumping but gives the state the power to step in only if local control is deemed deficient.
In the meantime, our prized water heritage is being used to water lettuce, alfalfa and cantaloupes. But we have to eat, don’t we?
