The residents of Rosario, Argentina’s third-largest city, are no strangers to crises.
When the country’s economy collapsed in 2001, a quarter of Rosario’s workforce suddenly was unemployed; more than half of its population dropped below the poverty line. Faced with skyrocketing food prices and shortages, some residents resorted to looting supermarkets for food.
"There were a lot of people who didn’t have jobs and, when you are unemployed and you have nothing to do and you have no food, it makes you sad and it makes you sick," said resident Tomasa Ramos Celia.
While residents struggled with an economy in freefall, another crisis loomed in the background. Climate change was heating up the city and making rainfall more erratic, leading to both flooding in Rosario and fires in the nearby river delta.
Rosario suffers from floods and the urban heat island effect, both of which climate change has exacerbated.
The municipality of Rosario responded with the Urban Agriculture Program, a finalist for the 2020-2021 Prize for Cities, which spotlights innovative approaches to tackling both climate change and urban inequality. The program, which gives low-income residents access to underused and abandoned public and private land to cultivate food, originally was intended to alleviate food scarcity and provide economic opportunities. Over the years, the municipality evolved the program into a cornerstone of its inclusive climate action planning.
Rosario’s urban agriculture provides healthy food to eat and sell
Prior to the economic crisis of 2001, many farmers in Rosario’s state of Santa Fe, an agricultural hub, were cultivating soybeans for export. By the early 2000s, Rosario had started to depend heavily on imported agricultural products cultivated with extensive use of pesticides to meet its own food demand.
The city’s Urban Agriculture Program (Programa de Agricultura Urbana, or PAU) began supplying local groups with tools, materials, seeds and training on agroecological production — growing produce without chemicals — in 2002. The program quickly expanded to cover 185 acres of the city, including seven Parques Huerta, or Vegetable Garden Parks, and various smaller neighborhood plots that were formerly underused or abandoned land.
To establish urban farming as a source of livelihood, the municipality also created spaces throughout the city for several permanent and pop-up markets, where urban farmers could sell locally grown produce and homemade goods such as pickled vegetables, sauces, syrups, organic cosmetics and preserved fruit and jams.
"Consumers benefit because our produce is fresher and more affordable, since it doesn’t have to travel [311 to 372 miles]," said Marisa Fogante, owner of two small agribusinesses selling in Rosario’s markets. "There is a virtuous circle where local producers grow produce that they can sell here, and consumers can easily access these foods by foot or on a bike."
Today, almost 300 urban farmers have temporary ownership of public and private land. About 65 percent are women who grow produce and sell it in Rosario’s markets.
The municipality also has expanded urban agriculture into public spaces, schools, marketplaces and a variety of social programs, especially those for youth and elders, establishing a culture around food production. Vegetable Garden Parks in low-income communities have become critical locations to carry out other social programs, including those for education and youth development. For example, municipality staff trained more than 2,400 families and 40 schools on agroecological production. They have since started their own vegetable gardens.

Reducing food miles and climate risks
Besides giving people jobs and new sources of livelihood, important climate benefits are gained from the Urban Agriculture Program. When monoculture triumphed over diversified food production, the city started sourcing food from more than 250 miles away, creating a supply chain that generates considerable greenhouse gas emissions. Today, almost 2,500 tons of fruits and vegetables are agroecologically produced in Rosario each year. Localizing vegetable production creates 95 percent fewer GHG emissions than produce imported to Rosario, according to a study by the National University of Rosario and RUAF Urban Agriculture and Food Systems.
The urban agriculture program gradually has expanded into Rosario’s peri-urban areas, just outside of the city. To institutionalize this expansion, the municipality created the "Green Belt Project," a new land use ordinance in 2015 that permanently designated 1.977 acres of peri-urban land to be used for agroecological fruit and vegetable production.
The Urban Agriculture Program’s expansion to areas outside the city protects the land from urban development and conversion to soy cultivation, helps reduce flood risk and lowers air temperatures.
"That's one thing that makes Rosario different from other places, that it has permanent spaces for urban agriculture," explained Antonio Luis Lattuca, an agrarian engineer and a creator of the Urban Agriculture Program. "[This] allows agriculture to improve the soil with time. When we work with these [agroecological] techniques, the soil becomes spongier and more absorbent. Instead of sliding and creating floods, water penetrates."
Land is often thought of as a city’s most valuable commodity. Yet Rosario’s approach of reserving underused and degraded land for urban agriculture shows that the goals of density and equitable urban development can be compatible and mutually beneficial. New green spaces within the city and outside it boost the density of the inner city by preventing further urban expansion, while sustaining livelihoods of low-income residents and yielding climate benefits.
Hardwiring social, economic and environmental resilience
Over the years, Rosario’s urban agriculture program evolved from an approach to put food on the table, to a tool for job creation, and more recently to a strategy for tackling climate change. It is now fully integrated into several of the city’s plans, including the Urban Plan of Rosario in 2007, the 10-year Strategic Plans of 2008 and 2018 and the Environmental Plan of 2015.
"Every public policy improves with continuity," said Rosario’s mayor, Pablo Javkin. “If you have continuity, you add to it. You add work, you add experience."

By weaving urban agriculture into strategic plans, the municipality has hardwired resilience into Rosario’s future. Because the program shrinks carbon footprints, increases resilience to climate risks and generates jobs and social inclusion, urban agriculture is as much an environmental infrastructure initiative as it is a social and economic one.
"If there are some things that we’re clear about the future, even within all this uncertainty, is that the local and the sustainable are going to have a great value," Javkin said. "I believe this is a program that addresses many of the issues that will become a priority in the cities of the future."
