Mexico’s agricultural output is constrained by a combination of water scarcity, degraded soils, outdated infrastructure, a complex land ownership system, and trade dynamics that have reshaped what the country grows. Roughly 70% of the land devoted to crops and cattle raising is affected by some form of degradation, and recent multi-year droughts have pushed estimated corn production down by 20 to 40 percent in affected regions. These challenges overlap and reinforce each other, making Mexican farming far less productive than its climate and geography might otherwise allow.
Water Scarcity and Irrigation Losses
Water is the single biggest bottleneck. About 78% of Mexico’s total water consumption goes to irrigation, yet the infrastructure delivering that water is remarkably inefficient. Of Mexico’s 6.2 million irrigated hectares, 90% rely on surface irrigation methods like flooding and furrow systems. An estimated 63% of irrigation water is lost between the canal infrastructure and the crop itself, through leaks, evaporation, and runoff. That means for every 100 liters diverted for farming, only about 37 liters actually reach plant roots.
The problem is geographic as well. Municipalities in western and central Mexico routinely demand more water than is naturally available, while coastal and lowland areas have relative abundance. Climate projections suggest the mismatch will worsen. Under the most severe warming scenario, up to 39% of municipalities in heavily populated regions could face outright water scarcity by 2080, with river watersheds like the Panuco and Moctezuma under increasing stress.
Drought and Extreme Heat
Long-term drought has gripped large portions of Mexico since the winter of 2022 to 2023. By the end of May 2024, nearly 76% of the country was experiencing drought, the most widespread since 2011. April and May 2024 ranked as the second and third driest of those months since records began in 1941, and the spring season overall was the driest on record.
The agricultural toll has been direct and severe. Mexico’s Ministry of Agriculture estimated a 20 to 40 percent reduction in corn production due to the drought as early as January 2024. By spring, coffee beans, sorghum, and other crops were also at risk. Some dams in northwestern Mexico dropped below 20% capacity, cutting off water for irrigation entirely. These droughts are not isolated events. They represent a pattern of increasing frequency and intensity that makes rain-fed farming, which covers the vast majority of Mexican cropland, increasingly unreliable.
Severe Soil Degradation
Nearly 45% of Mexico’s land surface shows some form of soil degradation. Chemical degradation is the most common type, affecting about 17.8% of the country, followed by water erosion (11.9%), wind erosion (9.5%), and physical degradation like compaction (5.7%). Of the chemically degraded land, the overwhelming majority, 92.7%, suffers specifically from reduced fertility due to the loss of minerals and organic matter.
The numbers are worse when you zoom in on agricultural land specifically. About 70% of the national area used for crops and livestock, roughly 34.5 million hectares, is affected by degradation. This means most of the land Mexican farmers actually work on is producing below its potential. Depleted soils require more fertilizer to achieve the same yields, raising costs and creating a cycle that is difficult to break without significant investment in soil restoration.
Inefficient Fertilizer Use
Mexican agriculture applies substantial amounts of fertilizer but uses it poorly. For fruit crops like avocado, lemon, and apple, more than 75% of national production results in excess nitrogen loss, meaning the fertilizer is applied at rates far beyond what the plants absorb. Some fruit and cereal operations use more than 150 kilograms of nitrogen per hectare, with the surplus leaching into the soil and waterways.
Only 2 to 15% of fruit production and 25 to 40% of cereal production is grown with what researchers consider efficient fertilizer use. The rest involves significant waste. This inefficiency increases input costs for farmers without proportional gains in yield, while simultaneously accelerating the chemical degradation of soils. Globally, cereal crops convert only about 33% of applied nitrogen into harvested grain, but Mexico’s figures for many crops fall well below even that modest benchmark.
The Ejido Land System
Mexico’s distinctive land tenure system has shaped its agricultural productivity for decades. After the Mexican Revolution, large estates were broken up and redistributed as communal holdings called ejidos. For most of the 20th century, ejido land could not be sold, rented, or used as collateral for loans. This meant farmers on communal land had little incentive or ability to invest in long-term improvements like irrigation, soil conservation, or mechanization.
The consequences show up clearly in the data. The median farm size for ejido farmers is 1.2 hectares, compared to 2.8 hectares for private landowners. Median corn yields on ejido land are roughly 929 kilograms per hectare, versus 1,050 for private farms. For wheat, the gap is wider: 4,274 kilograms per hectare on ejido land compared to 5,000 on private land. Capital investment on ejidos remains significantly lower than on neighboring private operations.
Reforms in the 1990s allowed ejido members to obtain formal land certificates, which in theory should improve access to credit and enable land rental markets. Certified ejidos have shown improved functioning of rental markets, allowing some farmers to adjust their plot sizes toward more efficient scales. But the impact on credit access and productive investment has been ambiguous. Surveys found roughly equal numbers of farmers believed certification helped or hurt investment. Decades of underinvestment left infrastructure deficits that legal reform alone hasn’t erased.
Trade Pressures on Domestic Grain Production
Mexico’s entry into NAFTA in 1994, preceded by broader trade liberalization in the late 1980s, fundamentally reshaped what the country farms and why. The U.S. and Mexico developed a complementary trade relationship: nearly three-quarters of U.S. agricultural exports to Mexico are grains, oilseeds, meat, and related products, while nearly three-quarters of what Mexico sends north consists of vegetables, fruit, beverages, and spirits.
This pattern exists because Mexico cannot produce enough grains and oilseeds to meet its own demand. Domestic food and livestock producers import large volumes of corn, wheat, and soybeans from the U.S. to manufacture value-added products like meat, cooking oil, and flour, mostly for Mexican consumers. The result is a structural dependence on imported staple crops. Mexican grain farmers compete against heavily subsidized U.S. producers operating on vastly larger scales with superior infrastructure, making domestic grain production economically difficult for many smallholders. Meanwhile, agricultural investment has shifted toward high-value export crops like avocados, berries, and tomatoes, further concentrating resources away from staple food production.
How These Factors Compound
What makes Mexico’s farming challenges so persistent is that they reinforce each other. Degraded soils require more water and fertilizer to produce the same yields, but water is scarce and fertilizer is used inefficiently. Small ejido plots discourage the capital investment needed to install drip irrigation or restore soil health. Drought destroys crops on rain-fed land, but upgrading to irrigated systems requires both money and water that many regions lack. Trade liberalization pushed farmers toward export crops that can justify higher input costs, leaving staple crop production underfunded and vulnerable.
The scale of the problem is significant. With only about 37% of irrigation water reaching crops, 70% of agricultural land degraded, and multi-year droughts becoming more common, Mexico faces compounding pressures that no single policy can resolve. Addressing any one factor in isolation, whether through land reform, water infrastructure, or trade adjustment, has so far produced limited results precisely because the constraints are interconnected.
