Columbia University Professor Dickson Despommier’s Vertical Farming: a green skyscraper for EXPO 2015
Dickson Despommier, a professor of Environmental Health Sciences and Microbiology at Columbia University, developed the idea of vertical farming with some of his graduate students. The goal is to grow crops and raise animals in skyscrapers in city centers. It is projected that by 2050 about 80% of the world’s population will live in cities; for such economical reasons, Desponmmier believes that the food growth should come from the inside.

Every Universal Exposition has left an innovative architectural landmark in the host city, such as the Eiffel Tower in Paris, and the Atomium in Brussels. The symbol of the upcoming EXPO of 2015 could very well be Skyland: the first vertical farm in the world. In this green skyscraper it would be possible to cultivate agricultural products within a city for its own inhabitants. But what exactly is vertical farming? It is an architectural approach based on two concepts: the vertical development of buildings, and the possibility of cultivating biological products from the inside. The inventor of vertical farming is Dickson Despommier, a professor of Environmental Health Sciences and Microbiology at Columbia University in New York City.
According to his estimates, the large 30-story building would be able to feed between 10,000 and 50,000 people every year. Despommier claims that vertical farming could be the solution to many of the problems that we face today, such as overpopulation and food shortages. Furthermore, vertical farming would reduce CO2 emissions that are associated with food production.

The vertical farm, thanks to hydroponics, would be able to produce a richer harvest protected from atmospheric conditions and parasites. The farming would also be less harmful to the land and the overall environment.
In this interview taken from CNN, Dickson Despommier explains his design philosophy.
