Short description of the intervention
The Toulouse based project Green My City is a community collective focused on promoting sustainable consumption and creating a sustainable environment, (Ref. 2) It anticipates constructing thousands of square meters of organic vegetable gardens on the roofs of the city of Toulouse, saving 50 tons of CO2 emissions per year. The project defines itself as a prospective tool, which intervenes in the stream of gardening initiatives: it maps, selects, and then accompanies the initiatives (Ref. 1). The project supports the realisation of environmental initiatives by engaging citizens, communities, businesses and designers to help create an urban oasis (Ref. 23).

Goals of the intervention
The Green My City project aims to encourage gardening initiatives in Toulouse in order to locally produce organic food, reduce energy consumption of vegetated buildings, increase local food distribution systems and reinforce social links by fostering urban gardening (Ref. 2). Project objectives include:
Greening cities and especially urban agriculture in order to increase the resilience of the territories to climate change and the scarcity of resources;
Improve the quality of life of urban dwellers, especially the most vulnerable;
Strengthen the social bond through actions and meetings around these themes (Ref. 2).
The project also suggests it hopes to federate and humanize the city's green initiatives, and in principle, the project aims to use green in cities to mitigate and adapt to climate change (Ref. 8) and reduce urban island heating effects (Ref. 22).
Quantitative targets
One initiative related to the project consisted of installing 100 vegetable gardens in 48 hours on the many composting sites in the city (Ref. 14).
Monitoring indicators defined
Expansion of vegetated and gardening spaces that accompany urban living (m^2) (Ref. 14)

Implementation activities
The My Green City's open data tool hosts a collaborative web platform linking future volunteer gardens, educational kits, and accompanying projects (Ref. 1). The project has therefore involved itself in different projects, (Ref. 6, 11) workshops, conferences, plantations, (Ref. 14) tours (Ref. 25) and initiatives throughout the city since starting in 2015. This included the 48 hour citywide initiative of 30 associations on March 17th 2017, implemented as a way of decentralising the creation of green spaces, edible landscapes and urban agriculture (Ref. 5, 7, 8, 9, 12, 13, 15, 16, 17). An example is the residence of Tibaous where inhabitants replanted fruit trees and aromatic plants (Ref. 4). An ephemeral urban vegetable garden was created at the square of Charles-de-Gaulle by the association Reflets meanwhile. Other activities were workshops on permaculture, creating wooden refuges to promote biodiversity, a balcony gardening workshop, sessions on cultivating wasteland, and making green graffitti using moss (Ref. 14). "Thousands of square meters of organic vegetable gardens on the roofs of the city of Toulouse, saving 50 tonnes of C02 per year. Designed to fight against urban heat islands, the Toulouse team's project Green My City won the national C3 Challenge" (Ref. 1).

The Green My City project is a community collective that defines itself as a prospective tool, which intervenes in the stream of gardening initiatives: it maps, selects, and then accompanies. It therefore elects representatives - companies, community, social housing - who have been previously chosen thanks to the development of an algorithm based on open data concerning the orientation of roofs and adapted structures. To refine the prospects of development, Météo France will also bring its expertise on the urban climate, and pollution to the project. It was also reported in 2015 the project was vying for the financial support of outside benefactors (Première Brique and la Mêlée numérique) to consolidate the viability of the project; (Ref. 1) developer of social innovations Première Brique have since been reported as having joined the project (Ref. 10).

Please specify social innovation
The project suggests that it hopes to federate and humanise the city's green initiatives, and thereby disseminate environmental practices among community level groups and activities. The provision of educational workshops and online-based learning tools are considered as innovative steps towards achieving this. (8) This includes a methodological "make [it] yourself" kit as a decided step towards realising citizen ecology. (10)
The project meanwhile promotes current trends in urban farming as part of its educational design, such as permaculture. The idea of permaculture is promoted in the project as a means to create an equilibrium of an ecosystem to cultivate fruits and vegetables as part of its educational workshops, lectures and conferences.

Comments and notes
Additional insights
2/Goals: The project considers that urban planning regulations are supposed to control and manage urban construction, while the logic of urban planning is to densify cities. Given this backdrop, Green My City wants to incorporate green and blue frames to encourage a return of nature to the city (Ref. 1).

Regular updates and announcements are available on Green my City's facebook page: https://www.facebook.com/greenmycity/ (Accessed: October 17, 2020).
