Land is a luxury that Singaporeans cannot afford. An island country of only 710 square km is already home to 5 million people. No wonder, Singapore’s skyline is thick with skyscrapers. In this high-density urbanized island, where 93 percent of food is imported, the notion of farming seems not only crazy but downright implausible. Yet, an ambitious entrepreneur says he can produce five times as many vegetables as a regular farm does right in the heart of Singapore’s thickly populated central business district. Thanks to his radically new farming technique, Jack Ng’s city farm is able to produce 1 ton of fresh veggies every other day, providing citizens a new and sustainable source of locally produced goodies.
