There’s a new breed of urban agriculture germinating throughout the country, one whose seeds come from an unlikely source.

Local government officials from Baltimore, Md., to Bainbridge Island, Wash. are plowing under the ubiquitous hydrangeas, petunias, day lilies, and turf grass around public buildings, and planting fruits and vegetables instead — as well as in underutilized spaces in our parks, plazas, street medians, and even parking lots. The new attitude at forward-thinking city halls seems to be, in a tough economy, why expend precious resources growing ornamental plants, when you can grow edible ones? And the bounty from these municipal gardens — call it public produce — not only promotes healthy eating, it bolsters food security simply by providing passersby with ready access to low- or no-cost fresh fruits and vegetables.

But is this really city government’s job?

As long as municipal policymakers strive to create programs to reduce social inequity and increase the quality of life for their citizens, I contend that it is. Access to healthy, low-cost food helps assure the health, safety, and welfare of citizens every bit as much as other services that city governments provide, such as clean drinking water, protection from crime and catastrophe, sewage treatment, garbage collection, shelters and low-income housing programs, fallen-tree disposal, and pothole-free streets.
