Location: Dortmund, Germany
Typology: Modular protected aquaponics
Urban area: Urban
Innovation type: Technological innovation
Main functions: Water recirculation – Polyculture – Research

HISTORY & CONTEXT

The aquaponics system of die Urbanisten is placed in the Union Gewerbehof in Dortmund. It was implemented in 2013 for demonstrative purposes. The installation consists of a 22m2 unheated greenhouse made of aluminum, plastic and glass, where the aquaculture and soil-less production are integrated. On the on hand, the aquaculture production is performed in a 1m3 IBC container and water is filtered by biological and mechanical processes. On the other hand, the soil-less production system is done on expanded clay in polyethylene boxes.

AGRICULTURAL & AQUACULTURAL CHARACTERISTICS

Crops: Tomatoes, Mint, Lettuce, Arugula, Lettuce, Lemon balm, Basil (African blue), True Water Cress

Fish: Grass Carp (Ctenopharyngodon idella), Tench (Tinca tinca)

Techniques: Aquaponics production: Aquaculture tank with filters (biological & mechanical) + Soil-less vegetables production with expanded clay

Irrigation: Tap water – Recirculation – Automatic irrigation

Use of renewable resources: –

Sustainable practices: Pesticides-free – Integrated pest management – Local production – Minimization of water consumption – Sustainable production of protein sources

Case study: SWUAS aquaponics system – Soest (Germany)

Location: Soest, Germany
Typology: Protected aquaponics
Urban area: Urban
Innovation type: Technological innovation
Main functions: Water recirculation – Polyculture – Research

HISTORY & CONTEXT

The aquaponics system at SWUAS (Fachbereich Agrarwirtschaft der Fachhochschule Südwestfalen) was implemented for research purposes. The installation started in May 2015. Regarding the aquaculture system, European catfish are held in three 1.1 cubic meter tanks, equipped with filters, feeders and warm water. The fish production is connected to the floating hydroponic system hosted in the greenhouse next door, growing in deep water culture beds (DWC). Aquaponics seeks for resource efficiency by recirculating the water between the two systems: the water from fish farming (aquaculture) flows into the plant basins (hydroponics) where the fish residues are used as fertilizers.

AGRICULTURAL & AQUACULTURAL CHARACTERISTICS

Crops: Lettuce (Salanova cook RZ), Lemon balm and Basil (African blue)

Fish: European catfish (Silurus glanis)

Techniques: Aquaponics production: Aquaculture tanks with UV disinfection and filters (biological & mechanical) + Floating hydroponic production with wooden beds

Irrigation: Well water (Elevated amount of calcium carbonate)– Recirculation – Automatic irrigation (Tap water is available)

Use of renewable resources: –

Sustainable practices: Pesticides-free – Integrated pest management – Local production – Minimization of water consumption – Sustainable production of protein sources

Special Issue Information

Dear Colleagues,

This Special Issue calls for papers that contribute to the assessment of the sustainability of urban agriculture, both by advancing methodological approaches and by providing results from case studies. Cities have been identified as an essential element in addressing global concerns, particularly due to the growing population, and food flow is key in the urban metabolism and in the design of future sustainable cities. Resulting from the environmental awareness of the globalized food system and urban social and economic gaps, urban agriculture has grown in recent years aiming at increasing food security while coping with climate change. Urban agriculture ranges from socially-oriented initiatives, which address social gaps (e.g., social inclusion, food deserts) employing low-tech techniques and educational programs, to high-tech for-profit farms, which focus on maximizing yields (e.g., rooftop greenhouse, aquaponics). The sustainability profile of such diverse forms of urban agriculture might consistently vary and contribute differently to the three dimensions of sustainability: Environment, society, and economy. To date, the environmental benefits of urban agriculture as a local production system, the ecosystem services of urban gardens (both environmental and socio-cultural services) or contribution to food security have been evaluated in specific case studies. However, studies covering sustainability assessments of social and economic aspects are limited, as are integrated methods for assessing urban agriculture.

This Special Issue aims at covering this gap by considering papers that evaluate the sustainability of urban agriculture, proposing new methodological approaches, and assessing new case studies that provide new data on the diverse nature of urban agriculture. New methods and data are essential to support decision- and policy-making for the design of sustainable cities. The consideration of the three dimensions of sustainability, integrated analyses, and quantitative approaches are of particular interest.
