Inclusive governance

The orchard of the Vallon was established by the city in an area that had historically served as an orchard fifty years previous (Ref. 9). A few pear trees had survived and gave rise to the idea of ​​reconstituting it. In 2014, the city planted apple, peach, pear, cherry, apricot and other fruit trees on one and a half hectares of greenery. "At the beginning of 2015, the association Le Verger du Vallon was born. With its members, its mission is to maintain these trees with a view to sharing knowledge and educational exchanges "(Ref. 9). "Called upon by the city of Rouen for the establishment of a participatory orchard, the social center wished to promote this project among the inhabitants within the framework of the arrow projects of the CAF (social security) de la Seine Maritime entering the field of financing "to support a cooperative project of residents initiated and built with them from a common concern " (Ref. 3, page Description).

The municipality of Catania, in collaboration with the University of Catania promotes sustainable agricultural practices in specific areas of the city with the project “Urbanhort” (Uban Horticulture systems for Resilient, Efficient and Sustainable cities). The main focus of the project was placed on biological, indoor and vertical gardening. The main goal of the intervention is to give value to the territory, to increment tourism, culture and the environment. What wanted to be tested was the efficiency of the practice in terms of price, health outcomes and the promotion of a correct diet. (Ref.1.)

The project might still be ongoing, however, no information was found on the website of Catania's municipality or on the website of the University of Agriculture of Catania for a later date that can show the current stage of the project (as of July of 2020).

In 2014, local residents of the St. Pauli neighbourhood of Hamburg supported by architects decided to reshape the Hilldegarden bunker built during WW II. They managed to convince the owner of the bunker, who currently leases the rooms of the bunker to a nightclub, a music school, an instrument store and a photography studio, to re-create the bunker in a way that pays special attention to ecological and social aspects. (Reference 1-3). ”The new project would see the space continue its mixed-use atmosphere, but topped with a massive public rooftop garden with walking trails.” The 800 sqm garden will use sustainable techniques for its operation, including renewable energies and greywater collection for irrigation and will offer a public garden where residents can engage in urban food production. (Reference 2) In September 2020, the reconstruction of the bunker is still in its early phases. (Ref. 8)

This local initiative has revitalized the most neglected places in the district and transformed them into green areas for leisure and recreation. The project resulted in the planting of new greenery (grasses, bushes, and flowers) and better maintenance of the existing plants, as well as installation of leisure and sports equipment (including benches and open-air gym) [1,2].

The Chartreuse Park has been chosen as a pilot site for the EU-funded VALUE project, enabling the City of Liège to finance and pilot a participatory requalification process for the Chartreuse Park. Since the acquisition of the site (about 20 hectares of park and green spaces), the City has taken several steps to recognize the historical and environmental potentialities of the Park and to integrate its values in the operations for the urban development of this old military site (the Fort de la Chartreuse). As a result of broad consultation with citizens, between 2012 and 2014, three circular walkways were created in the park connected to each other, enabling greater access to the park (Ref. 1).

This pilot project to create social gardens in Gdynia was developed by a cooperative of the local government, NGO sector and businesses. The project involved creating 3 (and finally 6) social gardens in different locations of Gdynia (Oksywie, Grabówek and Redłowo). They serve ecologic (greenery planting), horticultural (jointly managed vegetable and herb gardens), social (community integration) and educational (workshops on topics such as healthy lifestyle or building bird boxes) purposes. The gardens are being co-managed on a voluntary basis by the local communities with the help of an appointed gardener and an animator [1,4]. The project is based on 4 pillars: 1) social participation; 2) innovation; 3) social sensitivity; 4) food anthropology [5].

The Strasbourg Grandeur Nature Plan is engineered by Strasbourg Metropole and is focused on optimising the actions and resources and resources of local authorities in the maintenance of local biodiversity and improving the living environment (Ref. 7). It combines with local associations and citizens through organising interfaces (e.g. workshops, online tools) that allow relevant local authorities to engage with local projects and make interventions on the basis of proposals made by the community. The project aims at improving the maintenance and development of green spaces and biodiversity due to the environmental issues surrounding urban sprawls (Ref. 4).

The Danube Eco-District project is Strasbourg's first eco-districy and is based on previous experimental designs in sustainable urban living (Ref. 27, 30). It is situated at the heart of the axis Deux Rives, and is thus a strategic point of the large Franco-German Deux Rives project (Ref. 28). The district will have the capacity for 20,000 residents, and will include green spaces, green roofs, insect hotels (Ref. 1), various water management facilities (ditches, swales... etc.), and composting facilities (Ref. 4). The project aims to improve biodiversity, social equality, ecology, reduce urban heating, and promote sustainable consumption (Ref. 30).

The idea of ​​the project Redevelopment Of Place d'Austerlitz was to create an autonomous ecosystem, including plants and animals, with wild grasses and native trees that attract insects, mammals and birds (Ref. 4). The restructuring involved a whole mixture of paths, fauna, flora and riverside, all within a framework promoting urban ecology and biodiversity (Ref. 5). The project was conceived as "an archipelago of nature in the city" (Ref. 10, 12).

The NBS is a socio-ecological initiative to create an urban garden that would serve as an outdoor space for creative endeavours in the Cracow's district Podgórze. The project was implemented by an association of cultural institutions, NGOs, artists' groups, landscape architects, social activists, cultural animators and artisans, who also activated a group of volunteers from among the residents. The initiative involves several activities including greenery planting, horticulture/vegetable garden, ecological education and art workshops. Space is rented from the municipality as an act of protection of naturalistic landscape from over investment and new residential buildings in the area. It is surrounded by modern developments [1,3,4].
The social garden was established in 2013 and it is still functioning with its original purpose [3].
