Taking Urban Farming to the Next Level23
by Betsy Mikel
Dig deep through the produce section of a typical city supermarket and you might notice a disturbing trend.
Okay, not the crazy guy who’s whispering sweet nothings to the tomatoes, but the tomatoes themselves. Like the majority of the fruit and vegetables on the shelf, those tomatoes have probably traveled great distances to get to you, and that can have a devastating effect on the environment.
Vertical farming uncovered
The building blocks of vertical farming already exist. Hydroponics uses nutrient-rich water instead of soil to feed crops, and leftover water is recycled back into the system. This growing system is free of pesticides and herbicides, which are common in conventional farming.
Because vertical farms are stacked structures, they require less space than conventional farms while still producing a high quantity of food. Still, each square foot of real estate in an urban area is more expensive than its rural counterpart, which means vertical farms must ultimately produce a high yield of crops in a small surface area.
By 2050, 70 percent of the world’s population will be living in urban areas.
Though not all agricultural scientists accept that vertical farms can work, the rapid growth of urban populations could accelerate the technology, and many believe vertical farms could eliminate food deserts in inner cities.
By 2025 almost 60 percent of the world’s population will be living in urban areas, according to the United Nations Population Division. By 2050, it’ll be 70 percent. If conventional farming in rural areas continues to produce the food needed for our growing urban population, the cost of transporting it will continue to rise.
