Earmarked public budget

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 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].

The urban gardening project is a strategic employment and qualification measure which accommodates 14 long-term unemployed people guided and advised by 4 part-time employees of the Wuppertal District Service, consisting of a professional gardener, an instructor, a social education worker and a project manager. Coordinated with the Forestry Department of Wuppertal and the City of Wuppertal and in collaboration with non-governmental organizations, the participants of the programme plant and harvest vegetables and herbs in 19 high-raised flower beds on decentralized public and private spaces across the Ostersbaum district. The harvest is distributed to and shared by all residents. (Ref. 3) A further goal of the intervention is to increase cultivated green spaces and streets in the city district of Ostersbaum and thus to enhance the quality of life in the district. In 2017, the project was extended with an opportunity for beekeeping. (Ref. 8) Apart from its main goal of providing employment and assistance to unemployed people, the leaders of the project also offer educational opportunities for children and students, through educating them about the cycle of food production and creating an understanding of the origin of food. (Ref. 1)

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)

The intervention takes place in one of the most important parks in Palermo, and the area plays an important role, by hosting several plant and animal species, and the intervention consisted of creating an agricultural area within the park with a community-based approach. This proved that agricultural initiative had an economic role to play for the city, and at the same time can enhance social inclusiveness. (Ref.1.)

The Biodroom is a community garden where citizens can meet each other, children can play, and where vegetables are grown ecologically. The Biodrome started as a laboratory for art, gardening and ecology in the city: a temporary culture project with art manifestations, but is since 2014 it functions as a community garden that is maintained by citizens (Ref. 1).

A large-scale restoration of park Zapaden over 53 hectare had started in 2017, aiming to restore the aesthetic appearance of the park, and to preserve its authentic character and value for Sofia as the second biggest park in the city. Many activities were planned, including restoration of green areas, restoration of a lake and a rock-garden (renovating the artificial lakes, rivers, and waterfalls, and adding new vegetation), and adding new flowers and greenery. In addition, renovation and creation of new grey infrastructure such as playgrounds, alleys, lighting, cameras, irrigation systems, camp grounds, and more is planned. (Ref. 1; Ref. 2)

While it is difficult to assess how much work has been completed as of 2020, recent websites (from 2018) claim: "The park has two main parts – one has alleys built in it, as well as places for leisure and the other is a forest perfect for the hotter days of the year. The green part ends at the Smardana locality where people can find a lake." (Ref. 10)
