Consumers' love for avocados within the United States seems to know no bounds. From 2001 to 2020, consumption of this fruit loaded with healthy fats tripled nationwideand rises to over £8 per person per yr.
On average, 90% of those avocados are grown within the southwestern Mexican state of Michoacán. As with other trendy foods, resembling Acai berriesor as widely used as palm oil, intensive avocado cultivation causes considerable environmental damage.
My research on Latin American environmental history of the twentieth century examines how the transnational movement of individuals, food, and agricultural technologies has transformed rural landscapes in Latin America. I’m currently writing a book in regards to the development of a world avocado industry based in Michoacán, the world's largest avocado-producing region.

My research shows that growing avocados is economically viable within the short term for farmers – in Latin America, these are typically medium-sized farms and agribusinesses. It also helps producers – people in rural areas who grow subsistence crops. In the long run, nonetheless, every serving of avocado toast puts a strain on Michoacán's land, forests and water supplies. Rural producers, who lack the resources of large-scale farmers, feel these impacts essentially the most.
The environmental impact of monoculture
Michoacán is the one place on Earth where avocados grow year-round, because of its temperate climate, abundant rainfall and deep, porous volcanic soils wealthy in potassium, a significant plant nutrient. But even under favorable conditions, monocultures are never ecologically sustainable.
The introduction of homogenous, high-yielding crop varieties causes farmers to desert native crops. This makes the local ecosystem more vulnerable to threats resembling pest infestation and reduces food options. It also erodes fertile soils and increases using agrochemicals.
Monocultures may also contribute to deforestation. Mexican authorities imagine that avocado production will result in the clearing of 1,100 to 10,000 hectares of forest per yr from 2010 to 2020. And it’s resource-intensive: Avocado trees eat 4 to 5 times more water than the native pines of Michoacán, endangering water reserves for human consumption.
Bred in California
Avocados have been an element of the Mexican weight-reduction plan since ancient Mesoamerica, but the hate – the most well-liked variety on the planet today – was bred in what’s now California.
In the late nineteenth century Scientists from the US Department of Agriculture launched into a mission to gather and send home samples of food crops from all over the world. The goal was to adapt and grow these crops within the United States to scale back the necessity for food imports.
The collection of genetic plant material from Latin America and the imposition of quarantines on avocados from Mexico from 1914 onwards ensured that necessary support for the event of an avocado industry within the USAFarmers in California and Florida bred several varieties from the fabric collected by USDA researchers. But U.S. consumers within the early twentieth century were unfamiliar with this latest food and were hesitant to purchase avocados of various texture, size and color.
In response, farmers began choosing plants that produced avocados with small seeds, abundant flesh, hard skin, creamy texture and, most significantly, high yields. According to Industry knowledgeRudolph Hass, a mail carrier and amateur gardener from Southern California, got here across a brand new variety within the late Nineteen Twenties while attempting to propagate a range called Rideout.
Within just a few many years, the Hass avocado became the predominant avocado variety in California. In the Nineteen Fifties, Mexican farmers with connections to U.S. brokers introduced the Hass avocado south of the border.
How the Hate Islands modified Michoacán
In the early Nineteen Sixties, Michoacano Metaloupe farmers acquired land to expand their production by growing avocados, and shortly they focused exclusively on producing the Hass variety.
Many indigenous Purhépecha people, in addition to non-indigenous campesinos or peasants, rented or sold land to the emerging class of avocado farmers. In the Eighties, campesinos also began growing the fruit. This was an expensive, long-term endeavor: It took 4 years for the trees to supply marketable avocados, but farmers had to purchase the trees, clear land for them, and supply water, fertilizer, and pesticides to assist them grow.
Cantaloupe farmers could afford to speculate capital for 4 years without receiving any repayment. Campesinos needed to depend on loans or remittances from members of the family abroad to ascertain avocado plantations.
As production expanded, agrochemical dealers, nurseries and packaging plants emerged on Purhépecha's land, cutting down native pine trees and eroding the fertile soil. In 2003, Mexico passed a law that Prohibition of clearing of forests for business agriculturebut at the moment the campesinos in Michoacán were already growing Hass avocados on a big scale.

The Guacamole Wars: NAFTA and Avocados
After the adoption of the North American Free Trade Agreement In 1994, Californian avocado farmers campaigned maintain a quarantine imposed by the USDA in 1914 due to an alleged plague on Mexican avocado trees. After three years of drought in California and testing of orchards in Michoacán for pests, Mexico began shipping Hass avocados to the USA in 1997.
However only region certified by the USDA The first place where avocados were to be shipped to the United States was Michoacán. Mexico had to permit the USDA to station agents in Michoacán to confirm that the certified orchards met the agreed conditions to attenuate the chance of plant diseases.
Companies like Calavo, a fruit and vegetable retailer based in Californiabegan buying, packing and shipping avocados grown in Michoacán to U.S. customers, becoming major competitors to California avocado farmers.
Beyond monoculture
Today, avocados are considered one of the Most regulated exports from MexicoHowever, these rules do little to the environmental impact of the industry.
Farmers in Michoacán proceed to clear forests, spray agrochemicals, deplete aquifers and buy communal property in Purhépecha to convert it into smaller, private plots. Rising profits have fuelled violence and corruption, as some local authorities cooperate with organized criminal groups to expand the market.
During his visit to Michoacán on February 26, 2024, the US Ambassador to Mexico, Ken Salazar, promised that the US would change its protocol to Block the import of illegally grown avocadosHowever, this doesn’t restore local ecosystems.
In my view, it’s the incorrect responsibility to expect small farmers to guard the environment when the ecology and economy of Michoacán have been radically transformed within the name of free markets and development. And a boycott of Mexican avocados would probably only cause farmers to search for other markets.
Diversifying agriculture within the region and reforesting Michoacán could help restore the ecology of the Sierra Purhepecha and protect the agricultural economy. An indigenous community there successfully grows peaches and lemons for the domestic market and avocados for the international market and Planting native pines on their common areasThis is a possible model for other farmers, although it might be difficult to breed without government support.
In my view, importing avocados from different regions of Mexico and the world to scale back Hass market share stands out as the handiest environmental protection strategy. In 2022, the USDA approved the import of avocados grown within the Mexican state of JaliscoThis is a start, but Jalisco will follow Michoacán's example unless the United States finds more sources and promotes more varieties of avocado.
As US eaters change into more adventurous, try avocados from different sizes, shapes, textures, tastes and origins might be a call that’s each enjoyable and environmentally conscious.
