The Drying Planet
What’s needed most is governance of water that recognizes it as a crucial resource that determines both sovereignty and progress. Yet there is no international framework for water management, and only a handful of countries have national water policies of their own.
The United States has taken stabs at regulating its groundwater use, but in some cases those attempts appear to be failing. In 2014, California passed what seemed to many a revolutionary groundwater management act that required communities to assess their total water supply and budget its long-term use. But the act doesn’t take full effect until 2040, which has allowed many groundwater districts to continue to draw heavily from aquifers even as they complete their plans to conserve those resources. Chandanpurkar and Famiglietti’s research underscores the consequences for such a slow approach.
Arizona pioneered groundwater regulations in 1980, creating what it called active management areas where extraction would be limited and surface waters would be used to replenish aquifers. But it only chose to manage the water in metropolitan areas, leaving vast, unregulated swaths of the state where investors, farmers and industry have all pounced on the availability of free water for profit. In recent years, Saudi investors have pumped rural water to grow feed for cattle exported back to the Arabian Peninsula, and hedge funds are competing to pump and sell water to towns near Phoenix. Meanwhile, four out of the original five active management areas are failing to meet the state’s own targets.
“They like to say, ‘Oh, the management’s doing well,’” Famiglietti said, but looking out over the next century, the trends suggest the aquifers will continue to empty out. “No one talks about that. I don’t think it’s an exaggeration to say it’s an existential issue for cities like Phoenix.”
Both California and Arizona grow significant portions of America’s fruits and vegetables. Something has to give. “If you want to grow ood in a place like California,” Famiglietti asked, “do you just bring in water? If we deplete that groundwater, I don’t think there’s enough water to really replace what we’re doing there.” The United States might not have much choice, he added, but to move California’s agriculture production somewhere far away and retire the land.
Chandanpurkar, Famiglietti and the report’s other authors suggest there are ready solutions to the problems they have identified, because unlike so many aspects of the climate crisis, the human decisions that lead to the overuse of water can be speedily corrected. Agriculture, which uses the vast majority of the world’s fresh water, can deploy well-tested technologies like drip irrigation, as Israel has, that sharply cut use by as much as 50%. When California farms reduced their take of Colorado River water in 2023 and 2024, the water levels in Lake Mead, the nation’s largest reservoir, jumped by 16 vertical feet as some 390 billion gallons were saved by 2025. Individuals can reduce water waste by changing simple routines: shortening showers or removing lawns. And cities can look to recycle more of the water they use, as San Diego has.
A national policy that establishes rules around water practices but also prioritizes the use of water resources for national security and a collective interest could counterbalance the forces of habit and special interests, Salzberg said. Every country needs such a policy, and if the United States were to lead, it might offer an advantage. But “the U.S. doesn’t have a national water strategy,” he said, referring to a disjointed patchwork of state and court oversight. “We don’t even have a national water institution. We haven’t thought as a country about how we would even protect our own water resources for our own national interests, and we’re a mess.”
