View Island in Reading is a relaxing island with natural open space with grassy paths and seating near to the weir at Caversham Lock. A conservation project has been carried out to e.g. improve water flow, improve biodiversity, and improve the entrance to and around the island. The work has been carried out in consultation with Reading Borough Council, the Environment Agency and has been designed and constructed by Riverworks Ltd. (Ref, 1, 2, 3)

A communal bio-garden was created by a group of citizens in Sofia in 2014 on a municipal piece of land. The creation of the garden was supported by the Municipality through their programme “Green Sofia”. The aim of the project was to turn an abandoned and degraded green area into an “island of biodiversity” and a place for urban gardening. The garden contains herbs, vegetables, and flowers, dwelling places for useful insects, and a compost bin. The benefits of the garden have been ecological, educational, and social, including refugee integration. (Ref. 1; Ref. 2; Ref. 3; Ref. 4) According to their Facebook group in 2020, the 4 acre garden and the community that has organised around it is still thriving. (Ref 10)

Park Track North (Park Spoor Noord) is built on a former railway territory and was aimed to provide a social, green and mobility 'corridor' as the territory disconnected parts of the city (Ref. 1,4). Now, the park has a sustainable drainage system, allows a maximum diversity of people to use the park and has trees that will last for a long time. The park is further considered sustainable because of the use of FSC wood, re-used materials and energy-efficient lighting while the historical railway elements are restored or reused (Ref. 1,7).

A rehabilitation clinic in Bydgoszcz opened a rooftop garden for its patients. The garden was established in 1998 on the total area of 1 790 m2. The initiative was created with children of the Paediatrics Clinic in mind so that they could look at the garden instead of a concrete roof from their windows. Plants were designed in a way that their fragrances and colours are respective of the time of the day and the year. The spruce was also planted in the garden to be decorated as a Christmas tree in winter [1].

The NBS is a 200 m² green roof created as a complementary element to the concept of a low-emission building of the Demonstration Centre of Renewable Energy Sources at the School of Mechanical Engineering No. 2 in Bydgoszcz. The roof serves as a recreational area for students and visitors, provides thermal insulation for the building, increases biodiversity and improves the image of the construction [1].

The River Kennet and its tributaries make an excellent topic for introducing subjects to the curriculum at pre-school, primary and secondary levels. The ARK (Action for the River Kennet) project helps protecting the river and educate youngsters about the importance of water by providing educational projects for schools. The 'Trout in Schools' project as a partnership with Thames Water (funding and support), aims to hatch trout eggs and raise them until the trouts are grown enough to be released into the River Kennet (Ref.1, 2). The project has celebrated its 10th anniversary in 2018 and has engaged thousands of children (7).

The NBS was inspired by the first social garden created by citizens on Chrobrego Street. Later, the municipality provided funds for 4 additional projects. Social gardens were created in the housing estates of Wyżyny, Okole, Jary and Wilczak. Residents planted new bushes, flowers, trees, grass, and perennials, and arranged the existing nature in their pocket gardens. In some cases, they also established 'hotels' for insects and pollinators or created thematic paths. Common efforts are to grow healthy plants, herb and vegetable, and to create a friendly atmosphere in the gardens. The gardens are small, 100 square meters on average [1,4].

Since introducing the Tree Strategy, the Reading Council has working closely with partners and local people to promote the importance and benefit of trees. Work has included a (street) tree planting scheme. Reading has a committed Tree Warden Network (which has the objectives to e.g. engage the community and raise awareness of trees in neighbourhoods). (Ref. 1, 2)

The green roof and courtyard/patio on a new campus building of the University of Applied Sciences consist of trees and plants that reduce temperature and improve air quality. The plants are grown on a thick substrate layer that allows for extra stormwater storage. The vegetation also provides habitat for species such as insects, filters particulates from the air and reduces noise, and creates aesthetic value for patients in a nearby hospital (Ref. 1).

From 2006 onwards, the urban stream Wupper and its riverbanks were redeveloped and ecologically improved via several water management and planning measures across the city of Wuppertal. Initiated by the city administration and the public sector company Wupper, they aimed at improving the environmental- and water quality or the area and enhancing biodiversity in and around the Wupper. These efforts were accompanied by additional citizens' initiatives with the same goal. (Ref. 1, 2, 3, 9). According to the EU Water Framework Directive, 27 percent of the Wupper and its tributaries are now in good condition, which is well above the German average of 8 percent. The complete renaturalization is planned to be completed by 2025. (Ref. 12)
