Dissemination of information and education

Sofia is Europe's most polluted capital and the World Health Organization alarmed that Bulgaria ranks second in the world in terms of deaths due to air pollution per capita. In response to that, the coalition Sofia - Green Capital planned to buy neglected urban land and plant an Urban Forest in order to restore the green passes that lead the fresh air from the mountain to the city. The Urban Forest is expected to improve the air quality, sequestrate carbon emissions, and also provide a place for walks and play. (Ref. 1; Ref. 2). The planting process started in 2018 and around nearly 60,000 saplings were planted over 225 acres by over 6,500 volunteers and over 50 companies joined in. (Ref 7, 8)

"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).

Birkenhead Park is one of the most important public parks in Britain. It is registered Grade I in English Heritage’s Register of Parks and Gardens of Special Historic Interest. In 2002 to 2007, funding was made available to restore the park, and now in 2017 a master plan aims to further “enhance and secure” the park. (Ref. 1, 2, 3). Birkenhead park is considered the first publicly funded park in the world, and not only holds the Grade I in English Heritage’s Register of Parks and Gardens of Special Historic Interest award but also the Green Flag award. (Ref 6, 7, 8)

The community garden "Les Hauts Sèment" is located in Rouen in the district of Lombardy, being the first community garden of Rouen animated by the city in 2011. It is "an educational garden which has been created and is maintained by the gardener in association with users wishing to invest in the association. It is supported by different animations" (Ref. 1 and 2, page 12).

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).

The project is an initiative that is part of the environmental management system of the University of Murcia. This initiative aims to implement activities related to sustainable agricultural systems while also serving as a space for social cohesion for the members of the community (Ref 3). For this reason, a community garden was constructed and the slots are until 2019 distributed between members of the community of the university based on a bid (Ref 1).

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).
