According to the United Nations, the earth will house an estimated 9.7 billion people by 2050.
Consequently, more food will need to be produced over the next four decades than has been produced over the last 10,000 years. And with more than 99.7 percent of global food coming from land, and most of the arable land already accounted for, increasing yields per surface area is essential.
One crop production solution creating opportunities for investors, entrepreneurs and multinational companies is vertical farming, aka plant factories. Although nomenclature varies, the concept involves growing crops on urban rooftops or in high rises or other controlled, indoor environments, which build vertically in stacks as opposed to spreading horizontally.
