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].

This project is studying seagrass to learn more about the distribution and health of seagrass in the waters of the Solent. By learning about where seagrass exists it can be better protected. The Wildlife Trust have been visiting local seagrass sites including the harbour in Portsmouth (1). Measures that can be employed to help protect Zostera beds include Boat mooring management - a program of awareness to relieve pressure on seagrass in areas of high boating activity, such as the Solent (3) and restoration through seeding or transplanting seagrass and Improving habitat conditions to encourage natural regeneration and colonisation (3).

There have been different activities throughout the time to recover and improve the Malecon Botanical Garden. In 2012, the main activity was to recover the Malecon Botanical Garden by introducing a collection of Mediterranean species and of other ethnobotanicals plants and delivering some other environmental services to the location (Ref 1). In 2019, there were different works to rehabilitate the Garden for the September Fair, and also some other plans to create a cultural and artistic space within the Garden (Ref 10 and 11).
The project has completed its first stage, but there is an ongoing number of initiatives to rehabilitate and improve the garden (Ref 9 and 10).
Regarding the status of the project, the first stage has been completed, but an ongoing initiative to rehabilitate and improve the garden is taking place (Ref 9 and 10).

Forest of Bere has been identified as one of the key project areas of the Partnership for Urban South Hampshire (PUSH) Green Infrastructure Strategy. The goal is to allow urban populations of south Hampshire to have better access to quality green space. (1) Part of the forest, called Portsdown Hill, is a Site of Special Scientific Interest (SSSI) is on the boundary of urban Portsmouth and supports extensive areas of calcareous grassland where a wide diversity of typical chalk grassland plants and insects can be found. The last twenty years have seen extensive areas of scrub being removed and restored to open grassland. The project aims to restore the once flourishing natural habitat of the forest while providing more recreational opportunities to the growing number of residents in the surrounding areas, was well as improving the ecological connectivity of separate woodlands (1,2,4,5).

Portsmouth and its surrounding areas are under ‘serious water stress’ and water companies are being asked to take less water from some of their sources. This includes reductions to the amount of water that Southern Water can take from the rivers Test and Itchen in Hampshire. To address this, Portsmouth Water started the planning of a new Havant Thicket Reservoir.
The water to be stored in the reservoir will be supplied from surplus winter yield from the Havant & Bedhampton Springs. In winter, higher rainfall leads to a higher springs yield which flows into the sea, but a portion would now be pumped to the new reservoir. Long-term benefits of the proposed reservoir include enhancing the local environment and providing a new wetland habitat. (1,5)
In November 2020, the Havant Thicket Reservoir planning applications have been submitted to Havant Borough Council and East Hampshire District Council for validation. (7)

Wetlands provide a varying degree of treatment of discharged water and are ideally suited for the containment and treatment of polluted water runoff, being a holistic example of Sustainable Drainage Systems (SuDS). The Dublin Local Authority installed an Integrated Constructed Wetland to treat polluted water discharged from the urban area, with the aim of cleaning urban runoff and drainage water. It was meant to purify water that discharges into a pond, and later on into the Tolka river. The project has been very successful in treating polluted water effectively, according to studies. (Ref. 1; Ref. 3)

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).
