Talking large-scale farming from an entrepreneurial point of view, Lufa Farms in Montreal is pretty interesting.
On top of a two-story building the farm has built a 31,000-square-foot greenhouse. Over 40 different crops are being produced year round in the rather innovative greenhouses that can even stand the snow in the Canadian winters. For watering the plants the farm uses the irrigation system of the building. For some crops produces in this greenhouses, extra energy is needed. This energy is largely provided by the building too. This way Lufa Farms really uses the advantages of the urban conditions, which makes it a real urban rooftop farm. Lufa Farms is currently looking to expand its activities to the United States and find a way to scale urban farming.
City Farm in Tokyo sets itself apart from European and American rooftop farms.
The idea of producing local food for the community is the same and also in Tokyo activities are organized to let the urban population witness how food grows. The type of food though is slightly different and focused on the Japanese kitchen. Crops produced by City Farm includes rice, egg plants and soy beans. This requires different farming techniques. As rice grows in wet circumstances, draining and irrigating the roof will be different from Western-world rooftop farms.
On September 1st, Iimura Kazuki opened Omotesando Farm, a rooftop garden rental space in a central upscale commercial and residential district. The farm offers sixteen small plots at rents ranging from $170 to $250 per month.
The garden houses vegetables and herbs (and some bees, too!), The urban rooftop farm, called Dakakker, is an initiative of architecture firm ZUS and has sold its first veggies and herbs to local restaurants and shops. Also in Amsterdam, the Netherlands, the Zuidpark rooftop farm has opened its doors last year. Located along the city’s ring road, Zuidpark focuses (more than other urban farms) on activities, workshops and education, as well as on organizing special dinners with a view.
