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)

After 3 years of works, in 2020 the city of Gdynia revitalized one of its largest parks with a panoramic view on the rest of the city. Planned activities had included new greenery (suitable for the local climate conditions), rebuilding vegetation, creation of the educational paths, building water playground facilities and a sensory garden, open-air gyms and improved infrastructure for the disabled [1,2,3]. The final project focused on the renovation of the amphitheatre and the drainage system underground. Residents have been enjoying the park since June 2020 [7].

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 abandoned fishing harbour in Tallinn is a derelict, privately owned but publicly used open space approximately 5 hectares in size and known as the former fishing harbour (Kalasadam). It is part of the old industrial waterfront belt waiting to be regenerated in the future. It is a piece of ‘urban wilderness’ (Ref. 1). The site is a green open space with high recreational values. Inserting a few pieces of equipment and taming the urban wilderness very slightly seems to lead to a significantly increased number of users than before these developments (Ref 2).
A research study has been done to determine whether an urban derelict site could be regarded as only empty and meaningless (ref 1 and 2)

The Garden of (Re) Finds, was born in Lille in 1997. It is the first "community garden", directly inspired by the model of the gardens New York, which was created in France (Ref 1). There is an organic vegetable garden, a scented hill, a rainwater harvesting system, a regional hedge of regional species, a compost corner and a convivial shelter in corded wood and vegetal roof (Ref 2).

Since the decay of the former DDR, the lignite industry had a major downturn. Most of the mines were closed and its remaining craters re-naturalized and flooded with ground- or rainwater to be revived as recreational lakes. In the Leipzig area of "Neuseenland" up to 23 artificial lakes were created since the nineties by the respective mining company "Lausitzer und Mitteldeutsche Bergbau-Verwaltungsgesellschaft mbH" which has the obligation to securely and sustainably redevelop the area into forestry, agricultural, natural or recreational areas and reintegrate it into the adjacent landscape. The lakes have become important recreational areas for citizens (4, 8).

Opened in June 2006, the Jean-Baptiste Lebas Park, which occupies a space once used for illegal parking and marred by 11 lanes of traffic, is surrounded by the boulevard of the same name. This park plays an important role in creating an urban green space into a derelict grey area. The park helped to increase the biodiversity of the area. It has an area of 3-hectare (7-acre) and it contains a large lawn with flowerbeds, play areas for children and places for playing "boules" (Ref 1).

Zollverein is an abandoned colliery and coking plant near the center of Essen in Germany (Ref. 6). Since 1993 the mining here stopped, and the site was turned into a derelict area, so nature could win back its territory. Most of the railway tracks and the smaller industrial leftovers are now covered with moss, grass, and weeds (Ref. 4). After the site was recognized as a World Heritage Site in 2001, it started being developed as a multifunctional cultural, tourist and recreational center keeping and developing biotopes that emerged over time (Ref. 11).

When the national German railway company shut down parts of the former East station of Leipzig and its tracks in 2012, citizens developed an idea for its secondary use and came up with the concept of the "Parkbogen Ost" which represents a 5-kilometre long circle of bicycle lanes, footpaths and outdoor space surrounding the East of Leipzig. The city of Leipzig recognized its potential to connect the Eastern Leipzig with the city centre and developed the strategy further by issuing a "Masterplan Parkbogen Ost" as the base for a step-wise implementation of the project in 2013 (Ref. 5).

Located in the backyard of a memorial house, this NBS was created with 2 purposes in mind: to offer a green oasis to the inhabitants of Iasi but also to educate them since the garden itself relies on volunteers primarily who have the opportunity to come and work in the garden, assist in the process of growing food and learn how to lead a healthy life. In a way, this garden is seen as an escape from city life and it combines education with practical skills and community cohesion (1)
