Feeding rapidly growing urban populations requires innovative solutions that ensure efficient water, energy, and nutrients management. CITYFOOD investigates quasi-closed loop integrated aqua-agriculture (IAAC) systems to address this global challenge.

IAAC systems produce fish and plants, while re-using the fish water as fertiliser in nearly emission-free facilities. CITYFOOD will develop strategies to further the popularity and application of this space and resource friendly food production system in urban areas.

The multidisciplinary project team will involve city planners, urban farmers, scientists, entrepreneurs, community leaders, and engaged citizens to reach its goals.

Results and outcomes

The Aquaponic Knowledge Base is research-based, freely accessible and provides comprehensive background information on various aspects in the combined production of fish in recirculating aquaculture systems and plants in hydroponics as well as on the overlapping topics such as system design and -management, product quality, nutrient dynamics and integrated pest management.
