Creative agency Framlab has proposed building modular growing areas in Brooklyn.
The conceptual Glasir project comprises a stack of greenhouse-like modules.
They could be built in various locations across the New York borough where Framlab's research has found that 20 per cent of the population are food-insecure.
The system would use aeroponics, a process for cultivating plants in which crops are grown in mist environment rather than soil.
