French firm Vincent Callebaut Architects has unveiled a new vertical farm project tailored specially for Shenzhen, the southern metropolis of China (just a train ride over from Hong Kong).The Shenzhen Asian Cairn Farmscraper is a series of six towers, all inspired by the stacked stones meant to mark a hiking trail. According to Inhabitat:
The mixed-use eco-towers provide space for residences, offices, retail, recreation and food production. Integrated sources of renewable energy, sustainable farming, rainwater and grey water recycling all work in harmony to provide healthy living in a rapidly growing, dense, urban environment.
The call for vertical farms in cities around the world is a response to the burgeoning urban populations – particularly in China, where they have projected that 75% of the Chinese population is projected to be living in urban environments by 2030. Urban planners must now rush to find sustainable alternative solutions to generating energy, growing food and managing waste. This vertical farm project is a mix-use proposal that would support healthy living in Shenzhen.
The pebble-like structures, for example, are really steel rings that provide lots of natural daylight inside the building. The land surrounding the tower acts as an urban green space as well as a water reclamation area that can process rainwater. Additionally, the lush gardens provided in the structures act as both food production and air quality improvement for the community members.
This is only a proposal so far – no word on whether the proposal will come to fruition. But it sure would be interesting to see, if it were to be built!
