The Oriental Park of the City of Porto is an urban natural park designed by the landscape architect Sidónio Pardal. It will be one of the largest urban parks in the country and the second-largest in the city of Porto. This NBS focused on the transformation of a derelict, depressed urban area into a green space. The first part of the park was inaugurated in July 2010 and the municipality has plans to build it through several phases over the next decade until it reaches its project area. (1)

The Haumanngarten is a community garden in Essen founded by the Transition Town movement (Ref. 1). Since May 2015 a mixed group have been growing vegetables, herbs, flowers and berries on a former playground. Fellow gardeners with and without knowledge of gardening participate in the garden (Ref. 2).

The park, dedicated to the Sicilian judge assassinated by the mafia in the early 90s, was the object of a regeneration project by two associations (with the approval of the municipality). The initiative was practically implemented by kids of several schools in Catania, which were invited to the park with the intention of cleaning the area to make the spot available to new plants and trees. This is not just a natural intervention, it is of great cultural and social value for the importance of the character for the city and region. (Ref.1.)

Citizens have taken the initiative to create a community garden on an area where an abandoned building was located. With community engagement and support form public and private sector actors along with non-profit organisations, the garden was officially opened in 2011, bringing urban green space closer to the residents of the quarter. (1,2,3) The garden consists of recreational facilities, green space, a vegetable garden, fruit trees, a pond and activities are organized, which all largely contributes to social cohesion. The community has formed multiple groups that are responsible for parts of the community garden. (1)

Green space created behind Rock Ferry library on unused land. The plot of unused land, owned by the Wirral Council, signed a lease with the 'Grow Sow Well' project to run a volunteering scheme and sessions for the community (particularly aiming to help people with mental health issues). Grow Sow Well worked with residents, schools and community groups, bringing people together to celebrate their area and increase awareness of healthy eating and food production. (Ref. 1, 2) This lease has was transferred to the organisation called the Utopia Project (works with young people and includes horticulture). (Ref. 8)

A class of thirty students of a preschool "Jeanne Hachette of Rouen built, in the playground, an overgrown plant wall where climb non-toxic plants blooming from June to August (Ref. 1). Students engaged in a six-week educational module prior to planting the wall (Ref. 1). Engineering students from engineering school ESIGELEC assisted in delivering the program which taught students about the importance of plants and respecting the environment (Ref. 1).

This citizen-based initiative takes place in the heart of the city, in between the streets Montesano, San Michele, Carcaci, Sangiuliano. The project is the result of a collaboration among residents, artists and shop owners who are planning the regeneration of the area, which is currently in a state of decay. In particular, they realize green interventions (biological horticulture gardens, 100 new plantations) in the streets and on the buildings, to make the area more liveable and attractive for tourism. The initiative is fully supported by the municipality, who implemented the public areas to implement the interventions. (Ref.1.) This NBS has been an annual event, happening since 2013 (Ref. 2).

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).
