Many years of stress between the USA and Mexico over shared water sources changed into an precise water-cum-trade conflict in a single day. In a publish on Reality Social, U.S. President Donald Trump made good on earlier guarantees and threatened extra tariffs on Mexico if the nation doesn’t adjust to its obligations to ship water from the Rio Grande and its tributaries into Texas.
“Mexico nonetheless owes the U.S. over 800,000 acre-feet of water for failing to adjust to our Treaty over the previous 5 years,” Trump wrote. “Mexico has an obligation to FIX THIS NOW.”

Outdoors of the American West, trans-boundary water disputes typically appear to be one thing that solely impacts faraway locations, such because the eternal combat between Egypt and Ethiopia over the Grand Ethiopian Renaissance Dam; China’s risk to its neighbors with massive hydroelectric tasks; India and Pakistan practically going to conflict this 12 months over a shared river; and Turkey and Iraq practically doing the identical.
However the U.S.-Mexico water dispute has been brewing for a very long time, and as with these different disagreements, there aren’t any rapid options. Mexico, and northern Mexico particularly, has been hammered by drought in recent times, which has made all of it however inconceivable to satisfy its commitments below the 1944 treaty that regulates water move between the 2 international locations. Below that treaty, Mexico is obligated to supply the USA with a minimum of 350,000 acre-feet of water a 12 months, whereas the USA is obligated to ship much more Colorado River water the opposite means.
Mexican President Claudia Sheinbaum has tried to placate Trump, providing to launch treasured reserves of saved water earlier this spring after the primary tariff threats. However Trump is correct that Mexico has not fulfilled its obligations: There may be hardly a 12 months this century when Mexico’s deliveries of water to Texas farmers and ranchers got here shut to what they should be, and the previous few years have been particularly dry. The issue is that there’s not a lot left to provide: Water ranges within the Amistad Reservoir, the most important worldwide storage dam between the 2 international locations, stays under 25 %, and the Falcon Reservoir’s reserves are even decrease.
On paper, a minimum of, water disputes between the 2 international locations are supposed to be resolved by the Worldwide Boundary and Water Fee, not by presidential fiat. A part of the issue with the 1944 settlement—just like the Colorado River Compact and all worldwide water treaties from Egypt to the Indus—is that it was predicated on higher-than-average water flows. That implies that when river flows return to regular (or decrease), any individual has to tighten their belt.
However one of many causes that Trump has taken such a direct and sudden curiosity in a difficulty that has been simmering because the late nineteenth century is as a result of U.S. farmers and ranchers are struggling. Texas farmers are struggling to get the water they’d been having fun with for years; Midwestern farmers have harvests however fewer export markets than they’d like; and ranchers try to rustle up herds which have fallen to the bottom ranges in additional than 70 years.
That’s partly due to drought, partly due to culled beef herds within the wake of the COVID-19 pandemic, and partly as a result of the Trump administration’s commerce insurance policies have foreclosed previously buoyant export markets. Trump’s White Home is now having beef coverage conferences to try to provide you with an answer to hovering beef costs. In the meantime, the president is mustering $12 billion in tariff monies to bail out farmers who’re being harm by his commerce wars.
Underlying Mexico’s woes, and Trump’s newest tirade, is the local weather, which is altering and unremitting. What Mexico went by way of in recent times was irregular: Usually, when a cycle shifts from La Niña to El Niño, rainfall patterns revert to the imply. However they by no means actually did.
The Obama administration took a whole lot of flak on the time, and much more since, by arguing that local weather change was a nationwide safety risk. A decade in the past, it wrote: “Local weather change is an pressing and rising risk to U.S. nationwide safety, contributing to elevated climate extremes which worsen refugee flows and conflicts over fundamental sources like meals and water.”
Mexico now faces an extra 5 % tariff on its exports to its largest buying and selling associate if it doesn’t muster up extra water by the tip of the 12 months. It’s not completely clear what that tariff would apply to, since most of Trump’s tariffs on Mexico (like these on Canada) exempt items coated by the United States-Mexico-Canada Settlement. However it can make for an fascinating speaking level when that trilateral commerce deal comes up for assessment subsequent 12 months.
What the dispute does spotlight is the function that water shortage is coming to play in trans-national frictions and the function that local weather change has in exacerbating these water flows.
The US and Mexico, for all their historical past, are fairly good neighbors and may in all probability work this out. However the fallout from points such because the melting of the Himalayan glaciers on all of the downstream international locations that rely on these water flows might be a a lot larger concern, with billions of individuals at stake.
