As urban populations boom, urban agriculture is increasingly looked to as a local food source and a way to help combat inequitable food access. But little is known about how productive urban agriculture is compared to conventional, rural farming. A new study digs in, finding urban gardeners and hydroponics can meet and sometimes exceed the yields of rural farms. “Despite its growing popularity, there’s still quite a lot we don’t know about urban agriculture, like whether the yields are similar to conventional agriculture, or even what crops are commonly grown,” says Florian Payen, an environmental scientist at Lancaster University and lead author of the study, published today in AGU’s journal Earth’s Future. The new study compiles studies on urban agriculture from 53 countries to find out which crops grow well in cities, what growing methods are most effective, and what spaces can be utilized for growing. The researchers find that urban yields for some crops, like cucumbers, tubers and lettuces, are two to four times higher than conventional farming. Many other urban crops studied are produced at similar or higher rates than in rural settings. Cost efficiency remains an open but important question. Most studies on urban agriculture have focused on green spaces, such as private and community gardens, parks and field growing operations. Payen’s work includes “gray” spaces — places in cities that are already built but could be used for growing, such as rooftops and building facades. In both green and gray spaces, the study examines a suite of crops grown in soils versus hydroponics, horizontal versus vertical farming, and natural versus controlled conditions. “Surprisingly, there were few differences between overall yields in indoor spaces and outdoor green spaces, but there were clear differences in the suitability of crop types to different gray spaces,” Payen says. Certain crops like lettuces, kale and broccoli are more naturally suited to be grown vertically in indoor spaces than others. “You can’t exactly stack up apple trees in a five- or ten-layer high growth chamber,” he says, “though we did find one study that managed to grow wheat stacked up like that.” Other crops, like watery vegetables (e.g., tomatoes) and leafy greens, performed well in hydroponic environments. And crops grown in fully controlled environments can be grown throughout the year, allowing harvests to happen more times per year than in open-air environments, which leads to higher annual yields. But scientists will need to keep studying these systems to plan cost-effective agriculture solutions. The finding that urban agriculture can have similar or greater yields to conventional agriculture “is exactly what we have been waiting for in the urban agriculture research community,” says Erica Dorr, an environmental scientist at AgroParisTech who was not involved in the study.

Europe’s largest rooftop farm, Nature Urbaine in Paris, can produce 10 tons of produce each season. 

Hundreds of immaculate white columns dotted with small cylindrical outlets cover the rooftop of the Paris Expo Porte de Versailles exhibition center in the south of the French capital.

Fragrant basil, scarlet strawberries and unwieldy masses of dark green kale are among the colorful produce sprouting from each of the holes, which form part of a soil-less farming device known as an aeroponic growing tower.

“You see, there’s nothing in there,” says Eugénie Mercier, pulling out a bunch of kale to reveal its roots dangling freely inside the plastic structure. “When we water them, the plants take what is needed and we recycle the leftover water, so none is wasted.”

Mercier is manager of Nature Urbaine, Europe’s largest urban rooftop farm, which opened in spring 2020. At 14,000 square meters (150,000 square feet), its surface is almost as large as the playing area of the Stade de France football pitch not far away, and it can produce more than 10 tons of fruit and vegetables per season, using neither pesticides nor soil. According to manufacturer Agripolis, its computer-controlled hydroponic and aeroponic systems use 80% less water and produce 62% fewer CO2 emissions than a conventional farm for the same yield. Last year it was recognized by Ecocert, a French certification organization, as the first urban farm in the world to net offset carbon.

“It’s not just greenwashing,” adds Mercier. “This will really benefit the planet.”

Urban agriculture refers to the cultivation, processing, and distribution of food within cities and densely populated areas. This practice transforms unused spaces such as rooftops, vacant lots, and balconies into productive areas for growing vegetables, fruits, and herbs. Urban farming not only increases local food security but also promotes sustainable practices by reducing the need for long-distance transportation of produce. It can involve small-scale gardening, community farms, or even hydroponic systems inside buildings. Urban agriculture provides fresh produce, reduces carbon footprints, and fosters community engagement. Additionally, it contributes to green spaces in cities, enhancing biodiversity and improving air quality. This movement supports local economies by creating jobs and educational opportunities in food production and sustainability

In a conversation with Civil Eats, lead author Jason Hawes, a Ph.D. student at the University of Michigan, said this his team compiled “the largest data set that we know of” on urban farming. It included 73 urban farms, community gardens, and individual garden sites in Europe and the United States. At each of those sites, the research team worked with farmers and gardeners to collect data on the infrastructure, daily supplies used, irrigation, harvest amounts, and social goods. That data was then used to calculate the carbon emissions embodied in the production of food at each site and those emissions were compared to carbon emissions of the same foods produced at “conventional” farms. Overall, they found greenhouse gas emissions were six times higher at the urban sites—and that’s the conclusion the study led with. But not only is 73 a tiny number compared to the data that exists on conventional production agriculture, said Omanjana Goswami, an interdisciplinary scientist at the Union of Concerned Scientists (UCS), but lumping community gardens in with urban farms set up for commercial production and then comparing that to a rural system that has been highly tuned and financed for commercial production for centuries doesn’t make sense. “It’s almost like comparing apples to oranges,” she said. “The community garden is not set up to maximize production.” In fact, the sample set was heavily tilted toward community and individual gardens and away from urban farms. In New York City, for example, the only U.S. city represented, seven community gardens run by AmeriCorps were included. Brooklyn Grange’s massive rooftop farms—which on a few acres produce more than 100,000 pounds of produce for markets, wholesale buyers, CSAs, and the city’s largest convention center each year—were not. And what the study found was that when the small group of urban farms were disaggregated from the gardens, those farms were “statistically indistinguishable from conventional farms” on emissions. Aside from one high-emission outlier, the urban farms were carbon-competitive.

"When Cuba found itself abruptly cut off from trade with the Soviet bloc in 1989, the country entered into an economic crisis of unprecedented severity. Already sidelined from international trade due to US embargoes, Cuba became, almost overnight, a country detached from the rest of the world."

"Presented with a near collapse of its food provisioning system, the Cuban government responded with an overhaul of agriculture on the island, prioritising organic farming methods, the production of useful edible crops and the use of peasant labour. In urban areas, guerrilla gardening initiatives blossomed into new state-supported urban farming programmes, with widespread voluntary participation. These farming efforts have produced ‘what may be the world’s largest working model of a semi-sustainable agriculture’, [1] and in the process, resurrected the country’s local, affordable and accessible foodshed.[2]"

Endnotes: "Today the Cuban government has identified hundreds of large state-sponsored urban farms, 162 school gardens, 7,848 vacant lot gardens, and 34,970 yard gardens (González, 2008, p24)."

I need to test my soil. I had no idea.

a publisher reached out to me about doing a foraging book and I just like

no one wants that book i'd write, it would just be an entire book about all the different land use histories of urban spaces and why they're full of heavy metals. the plants I *want* to write and draw about would practically be a footnote compared to the worried-auntie-warnings

i insisted on including lead in the gardening book because I gotta

There is less accessibility to fresh fruits and vegetables in dense cities because how far fresh produce must travel from farm to supermarket to table.

To fix this 800 million people across the world, is practicing urban agriculture.
