Regeneration of the Central station area
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.)
Redevelopment of the Harris Garden
The Harris Garden is situated on the Whiteknights campus of the University of Reading. The garden provides an important amenity for all, giving pleasure to an increasing number of visitors, staff and students. It provides facilities for teaching, conservation and recreation. In 2010, with the closure of Plant Sciences, responsibility for the main part of the garden passed to the Facilities Management Directorate of the University and a major revitalisation programme began; with the "new purpose of conservation and recreation for all". (Ref. 1 , 2)
Green Wall on Office Building
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).
Backwaters management in the city forest
Management of natural lime-dry grasslands on gravel banks in Augsburg is conducted by the Landcape Association of the City of Augsburg (Bavaria, Germany). 300 ha of biotopes within the municipal area is maintained due to sheep grazing, mowing management, scrub clearance and reopening of potential expansion areas as well as further activities to create initial stages of immature soils and recreational purposes (Ref. 1).
The Green Ring
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).
Ko-Park
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).
A roof garden of the Diakonissen Klinik
A roof garden of about 370 square meters was built on the new building of the Diakonissenklinik in the course of the general renovation. The new intensive greening of the roof can be seen from many hospital wards and serves as an additional recreation facility for its patients (Ref. 1).
Green railways for the city tram
Thanks to an initiative by the citizens of Sofia, called Green Rails in Sofia, grass was planted by the Municipality on a an area of newly reconstructed tram line in Sofia. The cited benefits were heat reduction, noise reduction, aesthetics, natural water retention and drainage, and lower costs of maintenance in the long term compared to grey alternatives. The grassroots initiative “Green Rails in Sofia” are determined to keep putting pressure on the local authority to continue planting grass on other parts of the tram lines. (Ref. 1; Ref. 2; Ref. 3)
Mountain Forest Initiative
The ‘Mountain Forest Initiative’ was launched in 2009 by the Bavarian Ministry of Food, Agriculture and Forestry to restore the protective function of the vulnerable alpine forest in light of climate change, and was ongoing until 2014. To create a general sense of ownership in the process, the Mountain Forest Initiative sought the involvement of different stakeholders at the local level (e.g., private forest owners, land-use related authorities, hunters, nature conservationists, and tourism associations) (Ref. 1).
Where trees remember
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.
