Ing the deterioration of meals quality [52] plus the new aspirations of residents with regards to the link involving ecology, social justice and food production. In that context, for a low-income population with issues in acquiring sufficient food supplies, urban agriculture can facilitate access to specific foods [53,54]. Furthermore, urban agriculture can contribute to residents’ general amount of health [55] and education [54]. Finally, urban agriculture contributes to strengthening social ties [55,56]. Currently, as environmental difficulties intensify, urban agriculture is increasingly referred to as into play as a means to market sustainable improvement [53,54,57]. It truly is part of the repertoire of collective actions oriented toward the co-construction of a “sustainable city” [58]. It truly is this aspect that we are going to address together with the enable from the Lufa Farms case. 3.2.1. Lufa Farms in Montreal Lufa is certainly one of Canada’s top urban agriculture production experiments. It is actually innovative at a number of levels. Around the one hand, it was a pioneer in the implementation of commercial greenhouses on developing roofs [59]. However, offered that it includes the construction of rooftop greenhouses, it mobilizes high-level technologies for each production and management. In 2010, the firm built its initial greenhouse, using a surface area of 2973 m2 , on a disused developing situated within the borough of Ahuntsic-Cartierville.Climate 2021, 9,8 ofHarvesting and delivery of items began in April 2011. In 2013, a second greenhouse of 3995 m2 was built on a roof in Laval. In 2017, a third bigger greenhouse (5853 m2 ) was place into operation inside the borough of Anjou. In August 2020, lastly, Lufa inaugurated a fourth greenhouse, spanning 15,217 m2 , around the roof of a developing positioned in the borough of Saint-Laurent, doubling the productive capacity that the corporation had reached by then. Altogether, Lufa Farms offers fresh food year-round to almost 30,000 persons. More than fifty varieties of vegetables are developed annually in its 4 greenhouses (quite a few varieties of tomatoes, cucumbers, peppers, lettuce, eggplants, microgreens, basil and Swiss chard, amongst other folks). The production is carried out in accordance using the specifications of organic agriculture, that is definitely, devoid of pesticides, applying biocontrol (the use of Cy3 NHS ester Epigenetics advantageous CYM5442 MedChemExpress insects to combat pests) alongside rational use of water and electrical energy. Lufa relies on an incredibly complicated computerized program run by the Argus Titan software, designed for facilities management in protected environments which include agricultural greenhouses (The firm that markets this program is situated in British Columbia. See http://arguscontrols.com/about-argus/system-applications/ accessed on 23 July 2021). This application manages parameters including temperature, humidity, light, CO2 level, air exchange and circulation, snow loads, rain and wind protection. Furthermore, the method takes into account the protection of buildings and crops. three.two.2. The Creation and Putting into Operation with the Organization Lufa was founded in 2009 (“The name on the project is inspired by luffa, a climbing plant that grows in Lebanon, among other areas, where it thrives in urban environments. It decorates the walls and fences it covers, provides shade beneath pergolas, and supplies squash that could be cooked or dried to create sponges” [60].). The project was the brainchild of Mohamed Hage, who was joined by Lauren Rathmell, a biochemist by education and researcher at McGill University’s Macdonald campu.
