The United States is not going to run out of food. The country is one of the world’s largest food producers, and federal projections show crop yields rising steadily through at least 2033. But “running out” isn’t the only thing worth worrying about. The real pressures on the U.S. food system are subtler: rising prices that put meals out of reach for millions of households, infrastructure bottlenecks that could cause regional shortages during disasters, and long-term water depletion that threatens farming in key agricultural regions.
How Much Food the U.S. Actually Produces
The U.S. grows far more food than its population consumes. It is a major net exporter of corn, soybeans, wheat, and meat, shipping surplus production to markets around the world. USDA projections to 2033 show yields for all major staples continuing to climb. Corn is projected to rise from about 173 bushels per harvested acre in 2023 to 199 bushels by 2033. Soybean yields are expected to increase from roughly 50 bushels per acre to 56.5 over the same period, and wheat from about 49 to 53 bushels per acre.
These gains come from better seed genetics, improved farming practices, and precision agriculture technology. The USDA’s own summary puts it plainly: rising yields more than offset any declines in planted acreage, pushing corn and soybean production to record levels over the next decade. Physical food scarcity at a national level is not a realistic near-term scenario.
Imports play a smaller role than many people assume. Direct imports accounted for about 15 percent of total U.S. food and beverage spending in 2023. Those imports tend to be items like tropical fruit, off-season berries, wine, and seafood rather than calorie-dense staples. If trade were disrupted, Americans would lose variety and convenience, but not their core food supply.
The Problem Is Access, Not Supply
When people feel anxious about food availability, what they’re often experiencing is a cost problem. Grocery prices rose sharply between 2021 and 2023, and even though inflation has slowed, prices haven’t come back down. The food is on the shelves. The question is whether everyone can afford it.
In 2024, 86.3 percent of U.S. households were food secure throughout the entire year, meaning they had reliable access to enough food for an active, healthy life. That leaves 13.7 percent, or about 18.3 million households, that experienced food insecurity at some point during the year. Of those, 7.2 million households (5.4 percent) had very low food security, meaning members actually had to cut back on meals or skip eating because they couldn’t afford food.
These numbers have been creeping upward. The 2024 food insecurity rate is significantly higher than any year from 2016 through 2021. The same is true for very low food security. So while the country produces enormous quantities of food, a growing share of households struggles to put it on the table. Food insecurity in the U.S. is almost entirely an economic problem, not a production problem.
Supply Chain Weak Points
Even with abundant production, food has to travel from farms to processing plants to warehouses to stores. That distribution network has real vulnerabilities. A USDA analysis of cold chain infrastructure found that food distribution is heavily concentrated in a small number of counties. For meat, just 17 core counties handle a disproportionate share of national distribution, with five counties in Southern California ranking in the top seven. Perishable prepared foods are similarly concentrated in the Chicago area and California.
Those five Southern California counties dominate distribution of both meat and perishable prepared foods. A major earthquake, wildfire, or other disruption in that region would ripple through national food supply networks in both directions, affecting everything from farm-to-warehouse shipping to warehouse-to-store delivery. This doesn’t mean the food disappears. It means certain products could become temporarily unavailable in certain regions, with delays lasting days to weeks depending on the severity of the disruption.
The U.S. does not maintain a large-scale strategic food reserve comparable to the Strategic Petroleum Reserve for oil. The government has studied the concept of grain reserves built during good years and released during lean ones, but no such program currently operates at meaningful scale. Private inventories held by grain elevators and food companies serve as the practical buffer.
Water Depletion Is the Biggest Long-Term Threat
The most serious risk to future U.S. food production isn’t running out of land or seeds. It’s running out of water. The Ogallala Aquifer, a vast underground water source stretching from South Dakota to Texas, irrigates a significant share of the country’s corn, wheat, and cattle operations. It is being drained faster than rainfall can replenish it, and in many areas the water table has dropped dramatically over the past several decades.
Research from the University of Nebraska found that crop yields are already declining in areas where the aquifer has thinned the most. Fields sitting above the least saturated stretches of the aquifer, where the water-bearing layer is between 30 and 100 feet thick, start losing yield when water deficits reach just 16 inches, a common occurrence in Nebraska and other Midwestern states. During extreme drought conditions with a 37-inch water deficit, those fields produced roughly 19.5 fewer bushels of corn per acre.
The relationship between aquifer thickness and yield loss isn’t linear, which makes the problem accelerate as depletion continues. Reducing aquifer thickness from 330 feet to 230 feet costs only about 2.5 bushels per acre during drought. But reducing it from 230 to 130 feet costs 15 bushels per acre, a sixfold increase in losses for the same amount of depletion. As the aquifer gets thinner, each additional foot of loss hits harder. Parts of western Kansas and the Texas Panhandle are already approaching the point where irrigation from the Ogallala becomes impractical.
Wasted Food Is a Hidden Buffer
One underappreciated fact in any discussion about food shortages: the U.S. wastes an extraordinary amount of food. The EPA estimates that in 2019, 66 million tons of food was wasted in retail, food service, and residential settings alone. An additional 40 million tons was lost during manufacturing and processing. Most of that waste, about 60 percent, ended up in landfills.
That’s over 100 million tons of food discarded each year. Much of it is edible at the time it’s thrown away, lost to expiration dates, cosmetic standards, overproduction, and plate waste. In a genuine supply crisis, reducing waste could effectively stretch the existing food supply significantly without growing a single additional acre. It’s not a switch that flips overnight, but it represents an enormous margin of safety that raw production numbers alone don’t capture.
What Could Actually Cause Shortages
A nationwide famine-style food shortage in the U.S. is extremely unlikely under any plausible scenario. What is plausible, and what has already happened on smaller scales, is a combination of regional disruptions and price spikes that make specific products hard to find or hard to afford. The situations most likely to stress the food system include:
- Severe regional disasters that knock out distribution hubs in Southern California or the Chicago area, temporarily cutting supply chains for perishable goods
- Continued aquifer depletion that gradually reduces irrigated crop yields in the Great Plains, shifting production costs upward over decades
- Extreme weather years that hit multiple growing regions simultaneously, causing temporary price spikes for specific crops
- Trade disruptions that cut off imports of fresh produce, seafood, and specialty items, reducing variety more than total calories
None of these scenarios result in empty shelves nationwide. They result in higher prices, reduced selection, and greater hardship for the households already struggling to afford food. The 18.3 million food-insecure households in the U.S. are the canary in the coal mine. They’re already living the version of “running out of food” that is realistic in a wealthy, high-production country: not a physical absence of food, but an inability to consistently access it.
