Picture the bucolic little town of a fairy tale. At its core stand medieval buildings, a square where folks hawk their goods, and perhaps a well to provide water. Beyond the defensive wall radiate agricultural fields, where people toil to bring grains, fruits, and vegetables to market.

Invert that for modern times and you’ve got the idea behind “agrihoods,” communities designed around a central farm. Like a garden in a big city, agrihoods promise to boost food security, reduce temperatures, capture rainwater, and increase biodiversity. As climate change intensifies heat, flooding, and pressure on food systems, agrihoods could be a way to make urban living more resilient — not just more picturesque.

“Developers have a hard time offering open space, because they would like to build more housing,” said Vincent Mudd, a partner at the architectural firm Steinberg Hart, which designs agrihoods. “One of the few ways to kind of bridge that gap is to be able to use active open space that actually generates commerce.”
