Earmarked public budget

Owing to the city’s participatory budget, the residents created a well-equipped green recreational square in a vacant area of one of Bydgoszcz's neighbourhoods. The initiative involved the creation of an outdoor gym with several exercise equipment stations, as well as planting pollution-resistant trees and bushes - including oaks, maples, pine and spruce. The initiative aims to manage vacant space and increase access to the green space in this city district [1].

The initiative was funded from the participatory budget of the city and resulted in planting new greenery (including 70 trees and a thousand shrubs) by the local city lake 'Balaton' in Bydgoszcz. The justification of the project in its proposal highlights the practical and aesthetic values of green areas [1].

Milton Common is the second stage of the multi-million-pound Flooding and Coastal Erosion Risk Management scheme being developed across the north of Portsea Island, from Mountbatten Centre round to Milton Common. The overall project will reduce the risk of coastal flooding and erosion and provide the critical infrastructure the city will need over the next 100 years (6).
As the second phase, Milton Common included the instalment of a new rock revetment as a plans defence, the creation of a coastal path and three new earth bunds with new footpaths (6). The work has also included the demolition of Great Salterns Quay and restoration of the natural mudflat habitat (2,4).
The fully completed scheme will significantly reduce the risk of coastal flooding to Milton Common and the local area over the next 100 years; it will offer protection against a 1 in 500-year flood event providing one of the highest standards of flood protection in the UK outside of London (6).

The revitalization of two parks in Bydgoszcz - on 'Dabrowski’ and 'Liberty’ hills was planned in 2016 and successfully implemented in 2019. The project involved greenery planting, building health paths and outlook points, as well as new benches and a playground. It improved the aesthetic qualities of the parks, supported the effective management of rainwater and reduced noise from the surrounding areas [1].

The project aims to completely redevelop ‘Rozemaai’, a neighborhood in Antwerp, focusing on climate change adaptation, green spaces, and recreation. This includes a sustainable drainage system in which storm water flows via swales into a water stream with nature-friendly river banks, trees and bushes in the neighborhood, green parking lots, allotments and recreational facilities such as picnic tables (Ref. 1, 2, 3, 4, 5). Since 2019, the district has had a new, accessible park in which the Donkse brook plays a leading role (Ref. 7).

From 1850 to 1956 the area Eskesberg was a limestone mine, after that up until 1972 it served as a landfill. When taken over by the city of Wuppertal, groundwater contamination and outgassing required a large remediation to remove toxic substances and recover the area according to nature conservation guidelines. (Ref. 8) Since 2005, it has been turned into a nature conservation area covering 8.5 ha where several rare plants and animals have resettled and thus the area also serves as an important recreational space for residents (Ref. 1, 2, and 3). The project was initiated by the local government, who also collaborate with different partners for maintaining the nature conservation area, such as the biological station, which organizes excursions, performs monitoring on the terrain and sets up bee hives. Also, residents apart from visiting the area can actively participate in its maintenance as volunteers, guided by the city of Wuppertal and the NGO Biologische Station Mittlere Wupper. Furthermore, the nature conservation association of Wuppertal and scientists from the university of Cologne are involved in the intervention by conducting research on the terrain (Ref. 1, 2, 3 and 6).

The Foz do Douro Urban Park located in the west of Porto city is a green area for public use inserted into a recently developed urban area, which has been progressively been built along the Atlantic seafront since the nineteenth century and the Park is part of an overall project submitted in the competition Nuno Álvares Avenue Plan promoted by the Porto Municipality. With approximately 5ha, Foz do Douro Urban Park clearly contributes to increasing the rates of existing green areas for public use, increasing the availability of open spaces for the local and regional level.

On the territory of the former train station Vohwinkel (including the train tracks) a brownfield site of 15 ha was turned into a commercial urban area which was created as an economic driver for Wuppertal. However, the site was inhabited by the highly endangered sand lizard, which is why a species conservation island was created as the commercial park was being built. As a habitat of the endangered sand lizard species, the conservation area in the South-West of the commercial park remained free from construction development, and an adequate conservation concept was elaborated and implemented. The nature conservation area is maintained by the environmental protection department of the city. (Ref. 1 and 6). The project succeeded in its goal of creating a commercial area on the former Vohwinkel marshalling yard while simultaneously paying attention to the protection of the endangered sand lizard. (Ref. 2) Additionally to the conservation area within and around the commercial zone, lizards have also been relocated beyond the city limits as a biodiversity offsetting measure. (Ref. 8) Furthermore, the dried out Krutscheider stream, forming part of an important biotope system with its gravel surfaces, was dug out again to serve as a green corridor for compensation against the habitat loss. (Ref. 1, 4 and 6)

A project for the creation of a new central park was launched in 2018, where a harbor consisting of three docks used to be and is now used as primarily as a car park. The park was planned to consist of three large green spaces that are the exact same size as the original docks. As the green areas are planned to be surrounded by rows of trees, the park will look like New York’s Central Park. The park is set to contribute to Antwerp’s climate change resiliency as the central green area will contain a water basin in which stormwater can be stored temporarily and slowly infiltrate, which is enhanced by the riverbank vegetation (Ref. 1, 2, 6).

Offord Road community garden is a place for the residents of West Reading (i.e. those who live, work, go to school in the area). Reading Borough Council set up the community garden (i.e. the green space) at the Oxford Road end of Western Elms Avenue through a grant called ‘Section 106’ (thus giving the site back to the community in 1996).
