Almonds Are Bad.
The environmental case against America's most overrated crop
The almond industry has spent two decades expanding in one of the most water-constrained agricultural regions on earth, draining aquifers faster than rainfall can replenish them, decimating managed honeybee populations, and successfully marketing itself as a health food while two industry lobbying organizations fight every attempt at regulation.
California's Central Valley sits atop one of the largest groundwater aquifers in North America. It took thousands of years to fill. At current extraction rates driven largely by permanent crops like almonds, portions of it will be functionally depleted within decades.
The core problem with almonds isn't simply that they're thirsty. It's that they're a permanent crop in a drought-prone region with no off switch. A farmer can fallow wheat in a dry year. You cannot fallow an almond orchard — trees that go unwatered die, taking the entire capital investment with them. So the pumps run regardless of snowpack, reservoir levels, or drought declarations.
Between 2003 and 2020, almond acreage in California roughly doubled. This expansion happened during a period that included the most severe droughts in the state's recorded history. The economic logic was sound for growers — almonds command premium prices. The hydrological logic was not.
When the Almond Board of California faced criticism over these figures, the response was not to reduce water consumption. It was to commission a study using alternative metrics — comparing water use relative to nutrient content and economic value — specifically designed to produce numbers more favorable to the industry. The study was funded by the growers. The metrics were chosen by the growers. The results were used in industry communications.
California's Sustainable Groundwater Management Act (SGMA), passed in 2014, requires local agencies to bring groundwater basins into balance by 2040. The Almond Alliance — the industry's political arm — has actively lobbied against aggressive implementation timelines and in favor of weaker baseline measurements. The entity most dependent on groundwater extraction is fighting the rules designed to protect groundwater.
Almond trees are entirely self-sterile — they cannot produce fruit without cross-pollination from another almond variety, carried by insects. At commercial scale, this means one thing: every February, the U.S. commercial beekeeping industry essentially shuts down all other work and ships the majority of its managed hives to California's almond belt.
Approximately 1.8 million managed honeybee colonies are deployed for almond pollination annually — roughly 70% of all commercially managed hives in the country. They arrive in late January, work through March, and are then dispersed back across the country.
| Factor | Impact on Bees |
|---|---|
| Concentrated pesticide exposure | Neonicotinoids applied during and near bloom period cause acute and chronic toxicity |
| Disease amplification | Hives from 49 states in close proximity accelerates spread of Varroa mite, Nosema, and viral pathogens |
| Monoculture nutrition | Almond pollen alone is nutritionally incomplete; bees fed only almond pollen show compromised immune function |
| Annual colony losses | Beekeepers report 30–40% annual colony loss rates, with almond season cited as a primary stress event |
The commercial pollination industry has become structurally dependent on almond contracts to survive financially — and the almond industry has become structurally dependent on those bees to exist. The result is a system where both parties need each other, and the bees absorb the consequences.
This is the context in which some consumers choose almond products specifically to avoid "exploiting" bees — by which they typically mean avoiding honey. Honey requires bees to produce surplus nectar. Almond production requires bees to be trucked across the country, exposed to pesticides, fed a nutritionally deficient monoculture diet, and returned to their keepers with meaningfully higher loss rates than non-almond seasons.
The almond industry's expansion into marginal, drought-prone land was made economically viable in part by federally subsidized water delivered through the Central Valley Project and State Water Project infrastructure — systems built with public funds and operating at rates well below the actual cost of water delivery. Private growers have captured a public resource at below-market prices and used it to build a $6 billion annual export industry.
Almond Board of California — A federal marketing order funded by mandatory grower assessments. Ostensibly focused on promotion and research, the Board has used its research function to produce industry-favorable water data and shape the public narrative around almond environmental impact.
Almond Alliance — The industry's dedicated political lobbying organization. Per their own 2023 Advocacy Report, active priorities include lobbying against groundwater regulation and for decreased environmental business regulations on almond farming operations.
The pattern is familiar: a resource-intensive industry uses its revenues to fund the political opposition to the regulations that would constrain it. What makes the almond case notable is the scale — the industry's environmental footprint is unusually large relative to its consumer perception, which skews toward "healthy" and "natural."
Per liter of product, almond milk requires significantly more land and water than oat milk, rice milk, or soy milk — the three other major plant-based dairy alternatives. It has the highest water footprint of any mainstream milk alternative, driven by the water-intensive nature of almond cultivation in drought-prone California.
| Milk Type | Land (m² per liter) | Water (liters per liter) | GHG (kg CO₂ per liter) |
|---|---|---|---|
| Dairy (global avg) | 9.0 | 628 | 3.2 |
| Almond milk | 0.5 | 371 | 0.7 |
| Oat milk | 0.8 | 48 | 0.9 |
| Soy milk | 2.2 | 28 | 1.0 |
| Rice milk | 0.3 | 270 | 1.2 |
Almond milk uses less land and produces fewer greenhouse gas emissions than dairy. On those metrics, it is an improvement. On water — the specific constraint that matters most in the region where 80% of the world's almonds are grown — it is not. Oat milk, by comparison, uses roughly 8× less water per liter of finished product and is grown in rain-fed regions of the Midwest and Northern Europe.
A consumer choosing almond milk over dairy for environmental reasons would achieve meaningfully better outcomes by choosing oat milk instead. The almond milk category exists primarily as a successful marketing outcome, not an environmental one.
Most commercial almond milks contain 2–3% almonds by volume. The remainder is water, stabilizers, and added vitamins. A typical serving contains approximately 1 gram of protein, compared to 8 grams in dairy milk. You are paying a premium price for a product that is mostly water and contains almost none of the nut it's named after.
The critique of almonds is not that they are uniquely evil. It is that they have been successfully framed as a health and environmental good while carrying an environmental cost that is poorly understood by most consumers.
An industry concentrated in one of the most water-stressed agricultural regions on earth, dependent on a pollinator system it is actively stressing, protected by two lobbying organizations fighting the oversight that would constrain its growth — and marketed as a guilt-free, planet-friendly snack.
Eat almonds if you enjoy them. But understand what you're supporting, and don't confuse "plant-based" with "environmentally responsible." On water — the variable that matters most in California — almonds are not your friend.
