How are urban farming and rooftop gardens contributing to food security in cities?

Urban farming and rooftop gardens won’t replace the farms that supply most of a city’s food, but they can make local food systems more resilient and improve access to fresh produce.

Growing food in vacant lots, shared plots, and on rooftops puts some production close to the people who eat it. That can mean locally grown fresh produce is available through community gardens, farm stands, or food-sharing programs, with less dependence on long supply chains for those crops. Gardens can also give residents practical growing skills and strengthen community connections.

The contribution has limits. City farms generally produce a small share of total food, and leafy greens and herbs are easier to grow in tight spaces than staples such as grains. Rooftop projects also need safe access to water, suitable soil or growing systems, and buildings that can support the added weight. Their benefits depend on who can use the space and whether harvests reach households facing food insecurity.

So urban growing is best seen as one part of city food security: a source of fresh food and community capacity that can complement, rather than replace, larger farms and reliable distribution.
