Revitalization of park in the Kamienna Gora district
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].
Tree planting scheme
A tree planting programme (part of existing community greening initiative in the Mersey Forest) that is helping to transform Wirral into a thriving economic hub (trees planted on streets including Price Street, Cleveland Street, Argyle Street, and Hamilton Street, which are key transport routes around the Wirral Waters investment area). Trees will also be planted at Wirral Met College, as well as in social housing landscapes and gardens. (Ref. 1, 2). The project was completed in 2015 but similar initiatives have been taking place in Wirral since. There is no apparent connection between these projects and the 2012-15 project. (Ref. 7, 8)
Green cities and urban forests – Sicilian spring
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).
Recreational squares in Redlowo
This local initiative has revitalized the most neglected places in the district and transformed them into green areas for leisure and recreation. The project resulted in the planting of new greenery (grasses, bushes, and flowers) and better maintenance of the existing plants, as well as installation of leisure and sports equipment (including benches and open-air gym) [1,2].
Residents- and dog-friendly area
In this neighbourhood, this is the first initiative of this type which have utilized the neglected area for the creation of an open-air dog runway with agility track and a park for the residents. The project seeks to improve the aesthetics of the surroundings by planting greenery in the park and along the track. The wider goal of the initiative is to protect the area from further urban development in favour of more greenery in the city [1].
Chartreuse Park with interconnected public paths
The Chartreuse Park has been chosen as a pilot site for the EU-funded VALUE project, enabling the City of Liège to finance and pilot a participatory requalification process for the Chartreuse Park. Since the acquisition of the site (about 20 hectares of park and green spaces), the City has taken several steps to recognize the historical and environmental potentialities of the Park and to integrate its values in the operations for the urban development of this old military site (the Fort de la Chartreuse). As a result of broad consultation with citizens, between 2012 and 2014, three circular walkways were created in the park connected to each other, enabling greater access to the park (Ref. 1).
Regeneration San Berillo neighbourhood
The project aims at realizing a large urban park to link the city and the sea coast. It is a project of significant social value, as it takes place in a neighbourhood which has been in a state of decay for 50 years. The intervention includes new facilities for recreation and sport, but first of all new plantations and the creation of rooftop gardens. It would be the second-largest park of the city, by linking the city and the sea. (Ref.1.)
Covering the A7 highway
The aim of the project was to extend and cover one of Germany’s busiest highways, the south-north highway (A7). The highway had divided neighborhoods from each other and had had negative environmental effects like noise and air pollution. The new green roof will have three parts that connect the existing green surfaces to each other, these parts constitute the three phases of the construction. The urban areas in the vicinity of the noise-reduced motorway will be developed for residential construction. The project also includes the reconstruction of the Langenfelder Brücke in a way which makes the bridge wider, and also provides better noise protection for locals. (Reference 10) In September 2020, only the first phase has been completed, and the final completion is planned for 2028. (Reference 1, 3, 12).
Green wall in Infobox Gdynia
The first external green wall in the public space in Poland was installed on the surface of a 30 square meters wall of the Infobox building in Gdynia [1,2]. The project serves aesthetic purposes and aims to improve air quality. The wall was composed of the plants suitable for the Polish climate conditions [3].
Fortyfying the shores of the Baltic Sea
The project was implemented in the eastern coast of Poland in the Pomeranian Voivodship. A 5.98 km of the current sea coast within the administration of the Maritime Office in Gdynia was secured and fortified until 2015. The purpose of the initiative is to increase the number of marine shore sites restored to a former state by recultivating degraded areas, securing landslides, and securing marine shores from erosion [1].
