In founding the urban farming venture Cityscape Farms, Mike Yohay is banking on the fact that people are sick and tired of getting cardboard-tasting tomatoes trucked from Mexico in the middle of winter. And he’s betting that they’ll like enterprises that will provide jobs for neighborhood people growing “hyper-local,” organic food in greenhouses on rooftops and empty lots. People are already taking notice of this fledgling sustainable-food businessman; though he’s only been in the business of designing aquaponic greenhouse farming systems for urban rooftops for about a year, Yohay was recently named one of the ten most inspiring people in sustainable food by Fast Company Magazine. I recently got Yohay on the phone to learn the ins and outs of aquaponics, urban farming and his exciting new business venture.
Benjamin Rasmussen for The New York Times A system in Colorado uses wastewater from tilapia to nourish tomatoes. The tilapia are also food.
A small, portable aquaponics system. The term aquaponics is a portmanteau of the terms aquaculture and hydroponic . Aquaponics / ˈ æ k w ə ˈ p ɒ n ɨ k s / or pisciponics is a sustainable food production system that combines a traditional aquaculture (raising aquatic animals such as snails, fish , crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In aquaculture, effluents accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products from the aquaculture are broken down by nitrogen fixing bacteria , then filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the animals. As existing hydroponic and aquaculture farming techniques form the basis for all aquaponics systems, the size, complexity, and types of foods grown in an aquaponics system can vary as much as any system found in either distinct farming discipline.
