Fifth Dimension: Green roofs and walls in urban areas
As part of the Fifth Dimension research program of the University of Helsinki that examines green roofs from the perspectives of biodiversity and the three dimensions of sustainable development (ecological, social and economical sustainability), 8 green roofs were installed in Helsinki. The aim was to find economically viable solutions that are applicable to Helsinki’s and Finland’s conditions. The project experimented with green roofs in different parts of the country, over half of which are in Helsinki (ref. 1, 2, 3).
Father Collins Park
Situated on an area of 52 acres, Father Collins Park incorporates many sustainability-focused features and has won a number of awards. Over 1200 trees and 2000 native saplings were planted to help integrate the existing woodland, maximise biodiversity, and vastly increase the ecological value of the park. Also, wetland areas were created to filter and clean the water in the park as part of a recycling system that replenishes and helps clean the lake and water features. The wetland areas mimic the characteristics of natural wetlands and create a special ecosystem that encourages greater biodiversity in the park. (Ref. 1)
Green Roof of the Veneto Eye Bank Foundation
The Veneto Eye Bank Foundation, a social welfare organization and regional centre of reference for cornea transplantation and research into epithelial stem cells, is a distinct and iconic project which embraces architect Emilio Ambasz's philosophy of "The Green Over the Gray," or the landscape over the building. It is a triangular-shaped building with a series of landscaped terraces at each floor level on one side. On the opposite side, the building rises as a series of steps that lead to a flat planted roof garden turning it into an outdoor amphitheatre. The combination of the plantings and deep overhangs minimises the impact of heat loads by blocking sunlight during the middle of the day (ref 1).
Constructed Wetland
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)
Ecological Infrastructure in Port of Antwerp
The area of the Port of Antwerp is one of the most important habitats for threatened species, even at the European level (Ref. 1). Therefore, a species protection programme was launched in 2014 for the conservation of 90 protected species by means of creating an ecological infrastructure of green areas, green corridors and small green spaces that include spawning grounds, ecological river banks, and road verges (Ref. 1, 2, 3).
Ciaculli agricultural garden
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.)
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).
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).
Bidston Moss project
Until the 1990's Bidston Moss was a landfill site and was "unsafe for public access", thus giving a negative impression (close to several residential areas). Restoring work begun in 1995, and in 2006 development started in Bidston Moss through a Newlands scheme: including new features and landscape enhancements to “unlock the full potential” of the area (“as a valued and well-used community woodland for local people and wildlife.”). (Ref. 1, 2)
Natural Park of Augsburg Western Forests e.V.
The Natural Park of Augsburg - Western Forests covers a 1,200 square kilometer of the natural area. Founded in 2007, the park aims at preservation and development the natural biotopes in the area. As a supplier of timber, as a guarantor for clean air and pure water, and last but not least for recreation seekers, it is of outstanding importance in Bavarian Swabia (Ref. 1).
