You've heard of aquaculture (or fish farming) and you've heard of hydroponics (growing plants in liquid instead of soil). If you marry the two, you get aquaponics; an intergrated system that reuses water in a continuous cycle to produce an abundance of food. Some claim it is possible with this system to produce food for up to 300 families on an average urban lot.
The idea involves using nutrient rich efffluent from a fish tank to feed hydroponics plants which in turn clean the water to be returned to the tank. There is almost no water loss during the whole cycle making the system virtually drought proof.
I read about this type of system for the first time last week when I found this document on my web travels. Although fascinating, a picture is worth a thousand words, and today I found a short video of an aquaponics system up and running (very succesfully). It is of the Ecocity farm. Could this be the way of the future for our presently fossil fuel dependant food supply? I think it shows very strong promise for the cities of the future.
