The city is planning a 250-acre agricultural district, which will function as a space to work, live, shop, and farm food. Called Sunqiao Shanghai, it will include new public plazas, parks, housing, stores, restaurants, greenhouses, and a science museum. Some of the crops will be grown hydroponically indoors (i.e. under LEDs and in nutrient-rich water rather than soil).
Sunqiao will allow for produce to be grown closer to the city, while reducing the impact of land and water use that comes with traditional agriculture, Grove says. At the same time, he acknowledges the large energy use that comes with vertical farms, which rely on LEDs to grow crops.
They’re not crop circles, but they are the result of very practical agricultural engineering.
