China subverts pollution with contained vertical farms – and boosts yield

Around one fifth of arable land in China is contaminated with levels of toxins greater than government standards, according to 2014 data. That’s around half the size of California, and it’s a growing problem for a country that faces such levels of pollution they had to import $31.2 billion of soybeans in 2015 – a 43 percent increase since 2008. Scientists and entrepreneurs are working to come up with answers to growing edible food in a polluted environment, and shipping container farms or vertical gardening could offer answers. The toxins in China’s environment have made their way into the country’s food supply. In 2013, the Guangdong province government said 44 percent of rice sampled in their region contained excessive cadmium. Around 14 percent of domestic grain contains heavy metals such as lead, arsenic, and cadmium, according to research from scientists in 2015.

Beijing startup Alesca Life Technologies is testing them out. They turn retrofitted shipping containers into gardens filled to the brim with arugula, peas, kale, and mustard greens, and monitor conditions remotely via an app. They’ve already been able to sell smaller portable versions of the gardens to a division of a group managing luxury hotels in Beijing and the Dubai royal family. Alesca Life co-founder Stuart Oda told Bloomberg, “ Agriculture has not really innovated materially in the past 10,000 years. The future of farming – to us – is urban .” And they’re not alone in their innovation. Scientist Yang Qichang of the Institute of Environment and Sustainable Development in Agriculture at the Chinese Academy of Agricultural Sciences is experimenting with a crop laboratory, testing which light from the visible light spectrum both helps plants flourish and uses little energy . His self-contained, vertical system already yields between 40 and 100 times more produce than an open field of similar size. He told Bloomberg, “Using vertical agriculture, we don’t need to use pesticides and we can use less chemical fertilizers – and produce safe food.” Via Bloomberg Images via Alesca Life Technologies
