A field at the edge of a growing city may be worth far more than its market price suggests. It may produce vegetables sold in nearby markets, support local livelihoods and provide green space in an increasingly built-up environment. It can also help cities manage water, adapt to climate shocks and strengthen local food supplies. As municipal authorities decide where new homes and infrastructure should go, understanding what their land already contributes can help them plan for housing and food together.

This question lies at the heart of World Cities Day, which the United Nations will mark on 31 October under the theme “Regenerating the City: Adequate Housing for All.”

This does not mean protecting every agricultural plot from development. Cities urgently need more homes, and housing must remain a priority. The task is to make better-informed decisions about where development should proceed and where maintaining productive agricultural land can offer lasting benefits

According to the United Nations, cities are now home to 45 percent of the world’s population and are projected to account for two-thirds of global population growth between now and 2050.

Accommodating this expansion will require enormous investment in housing, infrastructure and public services. It also presents an opportunity to reconsider how food production and urban development can support one another.

Agriculture is already an integral part of the life and economy of many cities around the world. Within urban areas and along their expanding boundaries, farmers cultivate vegetables, fruits and other crops that supply local markets, generate employment and income, particularly for small-scale producers, and improve access to fresh and nutritious food.

Beyond food production, urban and peri-urban agriculture can also strengthen climate resilience, contribute to the restoration of urban ecosystems and support the development of greener, healthier and more sustainable cities.

The proximity of farms to consumers can be especially valuable for perishable produce. Proximity to markets can reduce transport distances and, when supported by adequate handling and storage, help limit losses of perishable produce. Urban and peri-urban agriculture can also diversify food supply chains, giving cities additional sources of food when longer distribution networks face disruptions.³

Yet the contribution of these farms is not always adequately recognized in urban development decisions. Land may be assessed primarily for its potential commercial or residential value, overlooking the food, livelihoods and environmental services it already provides.

As cities expand, these wider benefits deserve greater consideration. Agricultural land can help absorb rainfall, support biodiversity and contribute to urban green infrastructure. With appropriate safeguards, farming can also make use of suitably treated wastewater and safely processed organic resources. Once agricultural land is converted to other uses, such benefits can be difficult to recover.

This does not mean protecting every agricultural plot from development. Cities urgently need more homes, and housing must remain a priority. The task is to make better-informed decisions about where development should proceed and where maintaining productive agricultural land can offer lasting benefits.

Rosario, Argentina, illustrates how municipal policy can bring these objectives together. Following the country’s economic crisis in 2001, the city developed an urban agriculture programme that transformed vacant and underused land into productive spaces. It created opportunities for low-income households, supported fresh-food production and brought agriculture into municipal development planning.

Municipal authorities established arrangements to connect producers with available land, including public and private plots. Rosario subsequently incorporated agriculture into municipal planning and, in 2016, introduced a Green Belt Project to support agroecological production around the city.

Its experience demonstrates how local governments can integrate food production into wider efforts to improve urban livelihoods and the environment.

The lesson extends beyond Rosario. Urban agriculture cannot replace rural farming, which remains indispensable for feeding cities. Its particular contribution lies in complementing rural production, especially through fresh produce, diversified supply chains and stronger connections between urban markets and surrounding agricultural areas.

Realizing these benefits requires sound management. Producers need access to suitable land and safe water, alongside effective food-safety safeguards. Water-efficient irrigation, protected cultivation, improved logistics and the recovery of nutrients from organic waste can help cities use scarce resources more effectively. The most useful innovations are those that local farmers can afford, operate and sustain.

This broader approach is reflected in the Food and Agriculture Organization of the United Nations’ Green Cities Initiative , launched in 2020 with the ambition of improving health and well-being in 1,000 cities by 2030.

The Initiative connects urban and peri-urban agriculture with forestry, green infrastructure and sustainable natural-resource management. Through the Green Cities Network, municipalities can exchange experience, build partnerships and identify practical solutions suited to their circumstances.

World Cities Day offers an occasion for municipal authorities to act. Two measures would make a practical difference.

First, cities can integrate food and agriculture into urban and territorial planning. Mapping agricultural land, identifying its producers and understanding its connections to markets and surrounding rural areas can help governments make more informed decisions about housing, infrastructure and land use.

Second, municipalities can create conditions that encourage sustainable agricultural investment through appropriate zoning, secure access to land, improved market infrastructure and technical support. Rosario demonstrates how municipal policies can help make agriculture a lasting part of urban development.

The cities of tomorrow will need more homes, better infrastructure and thriving economies. They also stand to gain from the agriculture that sustains their populations. Recognizing its full value can help cities make better decisions about what to build, what to preserve and how to grow.
