NBS 4: Aquaponics
Aquaponics is the combination of raising fish (aquaculture) in tanks together with soilless cultivation of plants (hydroponics) in a symbiotic environment, whereby the fish waste water provides the nutrients needed to feed the plants.
Aquaponics is ideal for promoting local food production in areas with contaminated or poor quality soil. Similarly to NBS 3, food produced locally by locals can lead to healthier diets and contribute to community-building. Additionally the aquaponics systems will create green job opportunities.
This project intends to implement low-cost but stable aquaponics systems, which are easy to operate for non-experts and local communities.
Considered the focal point of proGIreg for Dortmund, a community-managed aquaponics system on 200m2 will be located next to the food forests and the orchard (NBS 3). Supported also by the city of Dortmund, the aquaponics system will provide new green job opportunities.
Supported with technology from Dortmund and expertise from the University of Zagreb’s Faculty of Agriculture, Zagreb will also test the potential of an aquaponics system on a 100m2 former industrial site.
Supported by the Dortmund Living Lab, Turin will test its first ever aquaponics system, with the potential for future replication, if successful. The small-scale community-designed system will be set up on an abandoned public site.
As a result of heavy industry, much of the soil in the area is contaminated. Aquaponics will enable communities to product their own healthy food from within the urban area.
