A Farm Grows In The City

By Betsy McKay, May 14, 2017

Billions of people around the world live far from where their food is grown.

It’s a big disconnect in modern life. And it may be about to change.

The world’s population is expected to reach 9.7 billion by 2050, 33% more people than are on the planet today, according to projections from the United Nations. About two-thirds of them are expected to live in cities, continuing a migration that has been under way around the world for years.

That’s a lot of mouths to feed, particularly in urban areas. Getting food to people who live far from farms—sometimes hundreds or thousands of miles away—is costly and strains natural resources. And heavy rains, droughts and other extreme weather events can threaten supplies.

Now more startups and city authorities are finding ways to grow food closer to home. High-tech “vertical farms” are sprouting inside warehouses and shipping containers, where lettuce and other greens grow without soil, stacked in horizontal or vertical rows and fed by water and LED lights, which can be customized to control the size, texture or other characteristic of a plant.

Companies are also engineering new ways to grow vegetables in smaller spaces, such as walls, rooftops, balconies, abandoned lots—and kitchens. They’re out to take advantage of a city’s resources, composting food waste and capturing rainwater as it runs off buildings or parking lots.

“We’re currently seeing the biggest movement of humans in the history of the planet, with rural people moving into cities across the world,” says Brendan Condon, co-founder and director of Biofilta Ltd., an Australian environmental-engineering company marketing a “closed-loop” gardening system that aims to use compost and rainwater runoff. “We’ve got rooftops, car parks, walls, balconies. If we can turn these city spaces into farms, then we’re reducing food miles down to food meters.”
