"Formerly a 10 hectare market gardening site, the Repainville area is rich in environmental potential: ponds, streams, springs ... the aquatic environment is present everywhere. There is a great variety of fauna and flora. As an ecosystem that is particularly rare in urban areas, protection and recovery measures are being undertaken" (Ref. 1). The restoration of the wetland of Repainville is part of a flagship project of the municipality in terms of safeguarding biodiversity in urban areas. With arrangements allowing the public to walk there without harming the biological and natural diversity of the place, the site has an educational dimension in order in particular to make young audiences aware of the preservation of the ecosystem (Ref. 7).

The municipality of Catania has promoted an initiative that involves schools and non-profit associations, for which available space for urban gardens and horticulture has been provided. The main aim was to regenerate areas which were used abusively as landfills and for criminal activities. What will be produced must strictly conform to the principles of sustainable production, by using biological products and 0 environmental impact techniques. (Ref.1.)

The Sand Motor is a hook-shaped peninsula that is artificially created at the coast near The Hague in order to protect the coast on the long-term. Not only provides the Sand Motor coastal protection, but it also allows for new forms of recreation and supports biodiversity as it creates habitat and allows for more varieties of species to live in the area. The Sand Motor is a unique pilot project in coastal management and follows the principle of 'building with nature' (1).

The project was developed as an integration garden for the visually impaired managed by the "La Lumière" ABSL (not-for-profit organization) and for the children hospitalized in the Citadel Hospital and for people hospitalized in psychiatry (Ref. 1). On their large terrace, they installed several bins in height to accommodate the vegetables. This garden is used for hospitalized children but also for adults admitted to psychiatry who find activity and serenity there. Since March 2008, the patio adjoining the garden has been designed to allow visually impaired and blind people to garden, and even a small corner is designed specifically for them in the kitchen garden (Ref. 2).

Port Sunlight River Park has been transformed from a closed landfill site to a 28-hectare park providing a popular community space with an array of walkways, wildlife, wildflowers, woodlands and a wetlands area. Port Sunlight River Park is a 30 hectare green space, park and wetland reclaimed from a former landfill site with a 37m high hill offering unrivalled views across the Mersey, Wirral and North Wales. (Ref 9). Autism Together were later brought in to help realise the Land Trust’s vision to provide a community site that makes a positive difference for local people and visitors, promoting healthy lifestyles in the process. (Ref. 1, 2).

The Center for Initiatives for an Ecological Transition (CITE ASBL) developed an eco-center; a center of demonstration of the techniques respectful of the environment, that functions as an educational community garden. They wanted to create an ecologically-managed and user-friendly green space, that is conducive to the exchange of knowledge and skills but also to mutual aid and dialogue (Ref. 1). Located on the meadow of the Bâneux, in the Saint-léonard district of Liège, the eco-center is integrated in the eastern part of the slopes of the citadel of Liège. (The plot of the eco-center is located on the vestiges of the old coal mine of Bâneux that was closed in 1942.) .Characteristics of the place include proximity to a multicultural urban center, post-industrial environment, accessible by public transport, natural area of tourist interest (Ref. 2).

This intervention involved the removal of sediment and revitalization of the banks along with the rehabilitation of the urban part of the Segura River in Murcia. This was done to strengthen the environmental condition of the river and improve the visual aspects and the access of citizens to the river (Ref 3 and 7). In 2020, they are building the second part of the project, where the aim is to build three different walkways that join the two sides of the rivers and that will connect specific places along with it (Ref 5).

It is a community garden initiated by the autonomous assembly of the Poblenou neighborhood. It has changed location a number of times, eventually occupying the empty lot of demolished buildings. Over time the garden has expanded, taking over an adjacent empty space, as well as other yards in the neighborhood. The garden is not maintained for strictly productivity purposes, especially because much of its soil has been contaminated by a soap factory. It is, rather, used as a space for social encounter and knowledge sharing on planting and working with the earth on a communitarian basis (Ref 1 and description provided by CEU). This NBS is also part of a wider movement, the 15M movement in Spain (Ref 1), which had influence on the creation of larger similar global economic 'occupy' movements (Ref 5). Video for the opening party of the 8th self-managed squatted garden in the Poblenou neighborhood, Barcelona from April 11, 2020 shows that the idea of the first garden has lead to the creation of at least 8 of these gardens in the city (Ref 6).

The Natural Park of Collserola (about 8,000 ha) is a forested area in the hilly Northern fringes of Barcelona. Since 1987, Collserola has been managed under a special protection plan and forms part of the European FEDENATUR network that aims at protected fragile peri-urban ecosystem for both their social and ecological functions. The park is jointly managed by a consortium including the Catalan government (Generalitat de Catalunya), the Barcelona Provincial Council (Diputació de Barcelona), the Metropolitan Area of Barcelona (AMB) as well as all adjacent municipalities (Ref 1).

The Parc Agrari del Baix Llobregat is located in the floodplains of the delta and lower valley of the river Llobregat, in the Catalan county of Baix Llobregat, in a central position within the metropolitan area of Barcelona. The territory of the park (nearly 3500 hectares), includes a rich traditional agricultural activity and comprises fourteen municipalities totaling about 818,000 residents. It is protected by a specific planning instrument and managed by the Barcelona Provincial Council (Diputació de Barcelona) (Ref. 1 and 9). The park acts as a green lung for the metropolitan area of Barcelona and at the same time as a pantry for Mercabarna, the large wholesale market that provides food and drink to the inhabitants of Barcelona and surrounding towns, although there is also production that is exported (Ref. 10). The Agrarian Park is the only one in the world so close to a large city and it promotes specific programs to preserve the productive values of the agricultural space and promotes quality local products and local consumption.
