Professor Dickson Despommier is a dreamer and I applaud him for it. So do many others. Since I first posted in August about Despommier and his vision of growing food in urban skyscrapers, this blog has gotten hundreds of hits a week under the search term, “vertical farming.” Sometimes it comes up as “vertikal farming” and I know that the Germans are curious, too.
Last night, before a sold-out crowd, the professor and other experts presented a panel entitled, “Designing Urban Farms to Feed New York” by the Municipal Art Society. In addition to Despommier, the panel was moderated by the Washington Post columnist Neal Pierce, and included:
- Colin Cathcart, a Brooklyn-based architect with a deep portfolio in sustainable building.
- Jenn Nelkin, Greenhouse Director for Gotham Greens, the first hydroponic rooftop farm in New York.
- Nevin Cohen, assistant professor of Environmental Studies at the New School. From the event literature: “His current research focuses on urban food policy, particularly innovative planning strategies to support food production in the urban and peri-urban landscape…”.
- Dan Albert, a landscape designer out of Seattle who was part of the team that developed the conceptual Eco-laboratory, a self-sustaining building that produces its own energy, food and water.
From the evening’s discussion I learned that we are going to address our problems of food supply and climate change in many different ways. While Despommier advocated for vertical farming, Nevin Cohen suggested growing food on urban public lands, among other ideas. What if cities grew fruit and nut trees in the parks that the public could harvest? Later in the talk, Cohen got cheers when he said that he still likens farming to soil, not purely hydroponics.
Jenn Nelkin offered a conciliatory acknowledgment that the answer is going to be in some of all these solutions. (And there were many more.) In fact, Nelkin continued, for experts in these topics, the nuances are still very much in development. Often when she’s in a conversation about her rooftop farm, she’s asked, “Which type of hydroponic system are you using?” The answers are evolving on many levels.
The tipping point will come when the financing solidifies. All the panelists agreed there is a growing demand for safe, sustainable, urban food production. We’re still searching for ways, however, to make the food affordable to the broad population and provide a good living wage to workers. Regretfully, one of the audience questions that did not get discussed was, “Can urban farmers afford to live in New York City?” I personally believe their role will be as important as doctors dispensing medicine, so I would hope so.
The theme of the night was big vision. Let’s imagine what the future can hold: Blooming verdant skyscrapers, apples from down the block, factory rooftops full of produce, and a good portion of the urban population ready to have our hands in the dirt. As my friend Michael Beneville says when he hears a good idea, “Let’s dream that into existence.”
