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)

Based on a neighbourhood survey the results pointed to a lack of green recreational spaces, in 2015 the citizens initiated a project to develop a new green square at the Zielona Street 19 in Gdynia. The project was implemented in 2018 and it aimed at improving the aesthetics of the district and provide green leisure space for the community. The initiative involves the management of the existing lawn, planting shrubs and trees, creating flowerbeds, building alleys and installing street lamps, creating variously-shaped wooden benches and litter bins, as well as building a fenced sandpit and a playground [1].

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).

The "Ciobarciu wetland" project resulted in the creation of a wetland area of ​​about 224 hectares near the city of Iasi (30 Km distance). The area of ​​nature thus became in spring and autumn a significant resting place for migratory birds, and the specific types of natural vegetation are growing again, constituting a natural habitat for the locales specific to these places. The project was developed by the National Administration of the Romanian Waters alongside the Dutch Government in order to restore the area and to include it in the ecosystem of the place (1)

The Woodland Trust’s Throne Wood, with its centuries-old woodland and recent planting, is a green oasis on the doorstep of the city of Belfast. The Trust adopted the woodland under their Community Woods Programme.
Throne Wood is a haven for wildlife and home to a number of native animal species and is an is an asset to North Belfast. (ref3). Future plans for Throne Wood include tree and wildflower planting to improve biodiversity and the removal of invasive species that hinder natural regeneration of the trees. (ref 1)

The medieval style Shared Garden Of Sainte-Madeleine Place development - situated in between two nearby schools - in 2009 was quickly claimed by the Association des Habitants Bourse Austerlitz Krutenau (Association of Inhabitants Bourse-Austerlitz-Krutenau) (AHBAK) neighborhood association because of its historic environment. The project turned the space into a shared garden, involving a collective composting area for organic waste, installing a rainwater recuperator, and planting local plant and vegetable species and new trees (Ref. 1, 2, 3).

The idea of ​​the project Redevelopment Of Place d'Austerlitz was to create an autonomous ecosystem, including plants and animals, with wild grasses and native trees that attract insects, mammals and birds (Ref. 4). The restructuring involved a whole mixture of paths, fauna, flora and riverside, all within a framework promoting urban ecology and biodiversity (Ref. 5). The project was conceived as "an archipelago of nature in the city" (Ref. 10, 12).

The Development Of The Banks Of The Faux Rempart Ditch is focused on the biological and ecological continuity of the right bank of the Faux Rampart (Ref. 6). The ditch was abandoned, underdeveloped and found to be lacking of the rich biodiversity otherwise seen in the surrounding area. thus, at the request of the local inhabitants, the City of Strasbourg intervened to revitalise the accessibility and greenery located at the area (Ref. 4).

Preserved from urbanization, the square of Chalampé is a bubble of greenery in the heart of old Neudorf. The square had become aged, under-equipped and surrounded by a thin vegetated strip (Ref. 1). The project aims to revitalize Chalampé Square by removing invasive species, replanting vegetation that will remove the shady character of the square and by recreating the plant lines that line the square (Ref. 2).

The NBS is a socio-ecological initiative to create an urban garden that would serve as an outdoor space for creative endeavours in the Cracow's district Podgórze. The project was implemented by an association of cultural institutions, NGOs, artists' groups, landscape architects, social activists, cultural animators and artisans, who also activated a group of volunteers from among the residents. The initiative involves several activities including greenery planting, horticulture/vegetable garden, ecological education and art workshops. Space is rented from the municipality as an act of protection of naturalistic landscape from over investment and new residential buildings in the area. It is surrounded by modern developments [1,3,4].
The social garden was established in 2013 and it is still functioning with its original purpose [3].
