The “Foodopolis” project addresses the politics, spaces, and actors at play in the global food system—from market to table, and from local to global trade. Today, there is an urgent need to reform the global food network, both to increase food sustainability in the developed world and to provide food security for an increasingly malnourished developing world. “Foodopolis” envisions a series of “floating farms” that would help meet a portion of New York City’s food needs locally rather than relying heavily on remote sources. The greenhouse farms would be paired with two types of food markets: global auction markets, which would use the internet to transmit real-time food prices—making wholesale food exchange more transparent—and public markets and outdoor parks, which would redefine the water’s edge by creating food spaces and recreational areas. Together, the floating farms, markets, and parks would transform New York City’s post-industrial waterfront into an infrastructure of urban food and park spaces.
