Urban farming utopias have been envisioned for decades—feed our urban dwellers by growing food vertically close to the people who eat it, a solution that can reduce transportation costs, save energy, and save water. Using a sensor-controlled hydroponic and aeroponic agricultural system, the Open Agriculture team at MIT’s Media Lab think they have the methodology to create an urban farm system that can one day be replicated all over the world—and potentially inspire a billion new urban farmers. Will data-driven precision agriculture change how, and potentially where, farmers farm?
