Vertical farming dates back thousands of years, citing the example of the Babylonian Hanging Gardens built 2,500 years ago. In Asia, the Sky Greens located in Singapore is one good example of an advanced vertical farming system, helping the country rely less on imports for its food supplies.
Also, Chinese state media recently reported that the country's scientists have established the world's tallest unmanned vertical farm in the southwestern province of Sichuan. Standing 20 stories, the vertical farm was built with oversight from the Chinese Academy of Agricultural Sciences in a downtown part of the provincial capital, Chengdu.
Chinese state broadcaster CCTV reported that Chengdu's vertical farm utilizes a range of technologies ranging from an automatic nutrient-supply system, energy-efficient artificial lighting that can emulate natural conditions and a control system based on artificial intelligence.
Among state universities and colleges in the Philippines, the Central Luzon State University (CLSU) in Muñoz, Nueva Ecija, has developed a vertical/urban farm technology demonstration system that occupies only 72 square meters and can accommodate 88 towers for growing crops. This makes the system developed by CLSU easier to start and scale up because of its modular setup.
