The future looks promising but it remains to be seen whether aquaponics becomes the “go-to” method of growing food in the city. This article from the International Herald Tribune via the NY Times explains more about this urban food growing method.
There may be questions about the future of aquaponics but one thing is becoming increasingly clear. Regardless of the frenetic drum beating by dirt huggers and fantasy farmers, the future is not in shoveling dirt and dung in often contaminated city ground. The future of “urban agriculture” inside the city is in the wise use of water and technology.
LONDON — In the Lowlands of Scotland, an old fire station donated to the community of Moffat for a symbolic penny has been converted into what may be the farm of the future. Forget about fields. Forget even about established norms of industrial agriculture. Using a new technology known as aquaponics, the Moffat farm, due to start production at the end of this month, will churn out fish and vegetables by the ton, in a space equivalent to a small factory.
Aquaponics — a combination of aquaculture, or fish cultivation, and hydroponics, or water-based planting — utilizes a symbiotic relationship between fish and plants. Fish waste provides nutrients for the plants, which in turn filter the water in which the fish live. Cuttings from plant are composted to create food for worms, which provide food for the fish, completing the cycle.
