Urban farm, it almost sounds like an oxymoron, but trust me, it isn’t. These farms are sprouting up (no pun intended) all over Chicago and other urban areas, and represent an efficient way to re-purpose under-utilized warehouse space in the city, often in economically distressed areas. Plus, they offer a tremendous opportunity for small-scale organic farmers to ply their trade in a supportive and mega-green environment.

I recently had the occasion to photograph two such urban farms: The Plant and Iron Street Farm. The former calls itself “a net-zero energy vertical farm and food business operation” whose purpose is to “promote closed-loop food production and sustainable economic development through education and research.” Now that’s a mouthful (no pun intended). And the later is a “seven-acre site on Chicago’s south side that produces local, healthy, and sustainable food year-round with a focus on serving, training, and engaging vulnerable populations.” Urban farms produce a wide range of products including cheese, vegetables, mushrooms, honey, beer, compost, and even fish. I suspect when we sang “Old McDonald had a farm” this wasn’t exactly the type of farm we were referring to.
