The tiny, densely populated city of Singapore saw the opening of the first commercial-scale vertical farm. The whole aim of the opening of the vertical farm is to decrease the dependence on food imports for Singapore.
Singapore is a dense city-state of just 274 square miles and almost all of this land is covered with buildings. That leaves little space to grow vegetables. As a result, the city currently only produces 7 percent of its vegetables locally, forcing it to buy from other countries.
Sky Green Farms has developed the vertical farm, which consists of 120 aluminum towers, each extending up almost 30 feet in height. It can produce over 1,000 pounds of three kinds of vegetables per day, all of which are sold in the local FairPrice Finest supermarkets.
