Urban farming is a growing trend around the world, and a topic we regularly cover here on iState. Here is an article in Futurism that covers urban farming in general, but, specifically a technique of farming called vertical farming, which is usually a form of hydroponics farming where trays are stacked up vertically to conserve limited, horizontal space.
New technologies are changing the equation, allowing people to grow food in places where it was previously difficult or impossible, and in quantities akin to traditional farms.
Urban farms can be as simple as traditional small outdoor community gardens, or as complex as indoor vertical farms in which farmers think about growing space in three-dimensional terms. These complex, futuristic farms can be configured in a number of ways, but most of them contain rows of racks lined with plants rooted in soil, nutrient-enriched water, or simply air. Each tier is equipped with UV lighting to mimic the effects of the sun. Unlike the unpredictable weather of outdoor farming, growing indoors allows farmers to tailor conditions to maximize growth…..
As people all over the world move to cities, urban centers sprawl to accommodate them. Often, that means taking over former farmland to support more people. In New Jersey, cities like Camden and Trenton are becoming more populous as they convert into urban spaces.
Vertical farming can limit that sprawl. “Vertical farms can actually come into these areas to recolonize the city and to take spaces that have been removed from producing anything,” Paul P.G. Gauthier, a vertical farming expert at the Princeton Environmental Institute, told Futurism.
But setting up an urban farm is often not an easy task. Finding enough space for an affordable price can present a significant obstacle for potential farmers. Vertical farmers also need to know how to operate more technology, including systems that control elements such as soil contaminants and water availability, that nature takes care of on a traditional farm.
