Integrated sustainability assessment of social and technological innovations towards urban food systems


Networking: Visit to Toronto’s urban agriculture projects and Ryerson University

Urban agriculture project have spread over Toronto, as it can be seen in the UA projects map of the Toronto Urban Growers website. Project are classified among community gardens (Toronto parks, Public housing, other), allotment gardens, school and childern’s gardens, urban agriculture businesses (producers), organizations, rooftop gardens, greenhouses, beehives and orchards.

Taking advantage of my visit to North America for the ISIE-ISSST 2017 conference, I visited Prof. Joe Nasr at Ryerson University (Centre for Studies in Food Security), who showed me some of the vibrant UA projects in the city of Toronto.

 

Ryerson Urban Farm – link

Taking the advantage of a former green roof, the Ryerson Urban Farm started to cultivate the roof of one of the Campus buildings with a pilot plot. Currently, the Farm crops the entire rooftop, including two recent beehives, have some spots with container cultivation around the campus, a food forest and a flower garden. The Farm employs soil-based ecological growing methods (crop rotation, composting, mulching). Tours, educational programs and community engagement complement the food production of the rooftop farm. Food is sold through farmers’ markets (in the same Campus), to restaurants and via Community-Supported Agriculture (CSA).

Evergreen Brick Works – link

EVERGREEN Brick Works is a “place where the world can experience sustainable practices that enable flourishing cities of the future”. Through the renovation of a deterioring heritage building of past industry in Toronto’s Don Valley, this new spot of the city is a public space and meeting point to exchange and disseminate about green cities, ecology, planning, design, technology and arts. Regarding urban agriculture, Brick Works hosts a farmers’ market on Saturdays, the largest market of Toronto which started in 2007, engaging a large community to get to know local producers. Evergreen also hosts a demonstrative Urban Farming Unit by Ripple Farms (see below). Furthermore, citizens can find local seedlings and urban gardening elements in the EVERGREEN shop at Brick works to develop their own urban gardens.

Ripple Farms – link

Ripple Farms is a social enterprise developing the aquaponics technology and business moel in Canada, with its first Urban Farming Unit placed in Evergreen Brick Works. The project aims to produce food locally, in an organic manner, year-round and seeking for resource efficiency (e.g., water and nutrients recirculation). Currently, the unit produces Tilapia and different greens (Arugula Microleaf, Buttercrunch Lettuce, Chard Flamingo, Frisee Endive, Little Gem Lettuce, Mustard Sprouts, Purple Basil, Sunflower Sprouts). Food production is combined with education and dissemination, such as workshops for citizens and schools.

 

FoodShare at Eastdale – link

The School grown program at Eastdale Collegiate Institute is one of the UA programs of FoodShare in the city of Toronto. The rooftop garden implemented in the former rooftop playground of the school is made of wooden beds and self-watering buckets. Soil with compost is employed for the cultivation. The main objective of the project is to educate and tran youth in food production, cooking and marketing. The education is also the main axis of the business model, complemented with the selling of the produce in farmer’s markets and to restaurants. A total of 65 crops are cultivated in this rooftop, dominated by leaf greens, which have the higher value in the market. Fertilization is performed with self-made compost, as composting and waste management is one focus of the School Grown program. During summer, the program employs students looking for summer jobs to fund their studies.

IMG_20170329_102131

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)
