2009 food Print Manhattan
How much space is needed to produce food for the entire population of Manhattan, including those who live there and those who visit? With current US production yields, this would require 150 times the area of Manhattan.
With a combination of hydroponic farming to boost crop efficiency, organic farming for animals to increase quality and animal well-being, while maintaining minimum livestock surface areas as specified by Dutch regulations (US organic farming regulations do not specify minimum), the area needed for food production is reduced to 46 times Manhattan.
To grow all food for Manhattan in one tower, a tower of 23 miles in height would be needed, including the food for animal production (or 8.7 miles tall without food). By distributing various ingredients over Governors Island in different towers—cereal tower, chicken tower, fruit tower, fish tower—a gigantic food city would appear next to Lady Liberty. Alternatively, distributing the towers over all the rooftops of Manhattan would result in a food layer of 656 feet on top of every building of the city. Food City by T?F, MVRDV Film: Wieland&Gouwens
