Improved air quality

This intervention is part of a broader masterplan regarding harbours and seacoast in Palermo, with a specific focus on the Cala coastal area. The waterfront has importance for the city not just as a harbour, but for its relational, cultural and recreational functions as well. In particular, the Molo Trapezoidale can become the new “water district” in which compatible port functions will be integrated with the existing urban functions and the new residential areas, as well as the new cultural and recreational services with new infrastructures linked with natural features such as green areas and trees. (Ref.1.)

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)

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).

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 Lolli-Malaspina area of the central station intervention aims to replace the current urban space and to replace it with a system that can complete and integrate the existing one, and generate a new centrality, transforming the current laceration into an urban seam. There are new gardens outside the central station, which link the different areas of the railway, and it has been implemented because the area of the central station is a strategical node for the city which has to be reinforced with new green areas. (Ref.1.)

On an office building, one of the largest green walls of Belgium was created (50.000 plants) that improves air quality, reduces heat stress, and improves biodiversity. The green wall also isolates the building, resulting in less energy use (Ref. 1-3). The wall consists of a variety of native plants and is irrigated with water collected on the roof of the building (Ref. 1, 2).

Instead of expanding the Ring of Antwerp to improve mobility, the municipality of Antwerp decided to use the space to create a Green Ring of 13 kilometers consisting of a wide range of projects (Ref. 3). This large city plan contains green spaces along the Ring, green corridors between those green spaces and with existing parks, a new green park, neighborhood green spaces, restoring the historical city wall and so on (Ref. 3). The plan also contains measures to improve water storing capacity (Ref. 4).

The creation of a new park in Augsburg within the reconstruction project of the Königsplatz (Konig square). The project combined two main goals: modern mobility in harmony with a new quality of life, accessibility of the natural environment inside the urban inner city. Formerly a traffic area, today it is a car-free habitat and green oasis for humans and nature (Ref. 1).

The intervention is a project of historic memory, it seeks to pay tribute to those individuals who were taken and assassinated as part of the resistance movement during the Civil War and the Franco dictatorship by planting a forest with Mediterranean species. In the forest, each tree represents one of these persons, thus combining aspects of recent history with the natural environment. (ref 1) Each tree represents real people, as the project collaborated with the families of the victims (Ref 1), to create a space of conscience about what happened in the Franco's period, as well as a memorial for them.

3000 trees were planted on 7 decares of land by 500 volunteers in park Zapaden on Earth day (22 April) in 2017. The initiative was supported by the Municipality of Sofia, and had the aim of making the city cleaner, greener, and more beautiful. The initiative also compensated for the illegal logging which had taken place in the park. (Ref. 1; Ref. 2; Ref. 3)
