Social gardens in Bydgoszcz
The NBS was inspired by the first social garden created by citizens on Chrobrego Street. Later, the municipality provided funds for 4 additional projects. Social gardens were created in the housing estates of Wyżyny, Okole, Jary and Wilczak. Residents planted new bushes, flowers, trees, grass, and perennials, and arranged the existing nature in their pocket gardens. In some cases, they also established 'hotels' for insects and pollinators or created thematic paths. Common efforts are to grow healthy plants, herb and vegetable, and to create a friendly atmosphere in the gardens. The gardens are small, 100 square meters on average [1,4].
Organized visits to the private gardens of Liege

This non-profit organization welcomes handicapped children during weekends and school holidays. Every year, about twenty gardens are open to the public and welcome more than 10,000 visitors. The totality of the funds raised by means of entrance fees goes to an association looking after handicapped children (Ref. 1)

Groene Mient - Sustainable Neighbourhood
'Groene Mient' (Green Commons) is a citizen initiative that realized an exceptional social-ecological residential project consisting of three housing buildings of energy neutral homes and a 3,500 m2 communal garden (1,6). Storm water is captured from the roofs of the buildings into bioswales, permeable paving is applied, the shared garden is 'eatable' and houses run on sustainable energy (1). The houses do not have a gas connection and have three different sustainable energy systems: heat pump with heat-cold storage, solar boiler or electric heating (6).

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.)
Roof-top garden (School Ferran Sunyer)
The educational project of a roof-top garden was integrated in the public primary school “Ferran Sunyer”, in the neighborhood of Sant Antoni, Barcelona. The project has motivated pupils to enter the world of urban horticulture, creating synergies with other lectures and has been well received by teachers and parents. This initiative aims to recover nature-appreciation values in children through the maintenance of a rooftop garden and orchard (Ref. 1). The rooftop school orchard has been featured in many videos in international media (Ref. 5).
The 100,000 trees project
The FUTURE - a project of 100,000 trees in the Porto Metropolitan Area - is a planned and coordinated effort of various organizations and citizens to create and maintain native urban forests in this region, which needs to enrich its biodiversity, sequester carbon, improve quality of air, protect their soil and contribute to a better quality of life for regional people. The 100,000 Trees Project for the Porto Metropolitan Area” intends to restore 100 hectares of urban forest with native trees. (1, 2)
Oriental Park
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)
Regeneration of Falcone park
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.)
Open gardens in Gdynia
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].
