Late this August, Vancouver-based Alterrus Systems began installing a 530 sq. metre urban farm on the roof of an underused downtown parking structure. It uses a semi-automated vertical-farming system to hydroponically grow leafy vegetables and herbs for local consumption.
Its automation suggests it won’t be a job creator, but in a press release Alterrus’s CEO emphasized the predicted land use and carbon pollution impacts of its VertiCrop system:
“Current food-production methods are ineffective in dealing with the challenges of growing populations and decreasing amounts of farmland. VertiCrop’s high-density urban farming is an effective way to grow nutritious food using fewer land and water resources than traditional field-farming methods.”
The produce will be packaged on site and can be delivered to markets in the city the same day as harvest. “The smaller carbon footprint involved is a critical point,” said [the CEO]. “Food production represents one of the world’s largest sources of unwanted gas emissions.”
The company says it expects the facility to produce more than 68,000 kilograms of produce annually.
