Improved stormwater management

The project was about restoration of the Aarhus river. The river was piped during the 1930s for hygienic reasons and to give space for road infrastructure. In 1989, the city decided to resurface the river. The river acts as a green and blue corridor running through the city centre. Furthermore, The City Council approved a plan for the recreational vision of the Aarhus River and e.g. flood prevention measures have been taken. (Ref. 1, 2, 3) The Aarhus Å project was completed in the years from 2006 to 2013. (Ref. 15)

The Green Bridge at the D2 motorway in Moravian Svätý Ján (Dúbrava locality) is a project under the Alpine Carpathian Corridor Project (ERDF). The project deals with biodiversity and is focused on building a safe and efficient passage for migrating animals over the D2 motorway connecting Bratislava and Brno (Czech Republic). The mountain ranges of the Alps and the Carpathians, which straddle the border of Austria and Slovakia, are the largest sources of biodiversity in Central Europe. The Corridor’s structure has created a forum for the managers of these regions to share ideas and develop solutions that can be applied within the entire region, instead of only per protected area. To ensure long-term continuity, key stakeholders are party to a Memorandum of Understanding that can contribute to sustainability in their area of responsibility. (1, 5, 6)

In 2009, the city of Montpellier launched a large census project to valorize its abandoned areas. The study gives guidance on the management of abandoned areas in Montpellier, particularly in connection with environmental education and awareness objectives (Ref. 2). The strategy aims to preserve and promote the natural heritage of Montpellier; promote wastelands as reservoirs of biodiversity, tools for connecting natural spaces; protect and enhance the great green flows accompanying watercourses (biological links and privileged sites for fauna and flora); and develop a network of soft transport throughout the city based on the green network (rivers, agricultural, natural and park areas) (Ref. 4). "The spaces have been classified according to their context, their origin, their potential. This sometimes subjective typology presents a classification of the wasteland and makes it possible to take a particular look on each land. Surfaces of all shapes and sizes fall within this operational classification." Four Experimental projects include: Zenith Friche, Promenade of the Lironde, Pastourelle, Combemale" (Source: uploaded document).

The waste management company BiR built a new terminal with underground waste collection using suction techniques. In connection with this new establishment, a green wall and a green roof were installed by the landscaping company Wikholm. In 2015, the plant wall at Jekteviken Terminal was the largest green wall in Norway, covering 350m2 with its 17 000 plants. (Ref. 1) In addition to providing aesthetic value, the wall also insulates the building, cleanses the air, and binds dust. (Ref. 6) Irrigation of the wall is automatic, as the wall collects and stores rainwater and use it when needed. (Ref. 1)

The agriparc of the Mas Nouguier is an agricultural reserve entirely maintained by the city of Montpellier. Conducted in organic agriculture, the estate contributes to the preservation of the identity of the territory and to the valorization of the living environment. Accessible to all, it offers a beautiful walk in the middle of the vineyards. Apiaries are used to develop educational workshops and to collect honey with school children. Olive trees, centennial pines and a large meadow come to embellish this little bit of countryside in town (Ref. 1).

The current intervention involves restoration of Bohrova park in the city district of Petrzalka with the implementation of water conservation measures (9).

The Street Office (Gatukontoret) and VA Syd rebuilt Fjärilsparken (The butterfly park) in Bunkeflostrand (Malmö). For the shallow stream that runs through the park the slopes of the dikes have been made flat, meadow vegetation and wetland-plants planted in the wetlands. An area east of the park was built with houses and stormwater was managed in new ways (ref. 1). Opening the park up to the sea, flower beds were planted for richer plant and wildlife, butterfly-attracting plants were planted, lighting for safety was installed and areas with benches and bridges were created (ref. 1).

The revitalisation of the park Gaštanica Koliba in Bratislava Nove Mesto is intended to stop the degradation of its ecosystem, preserving existing vegetation while improving the local climate and efficient use of rainwater. Over 100 trees were treated, including some of the local population of chestnut trees. A local seepage pit was installed to retain water both to the benefit of the local vegetation as well as to prevent erosion and landslides. The park has also been fitted with recreational facilities and is now illuminated to improve its accessibility for the local population. (7, 8, 9)

Metrodom Panorama is a private investment containing four 17-storey residential buildings. Following the model of Bosco Verticale of Milan, the facades of the buildings will be created as vertical forests. In the balconies of the buildings 3 to 6 meter high trees are planned to be planted. The construction was finished and the buildings were opened for residents in 2020. As the building is still very new, the green elements of the building are not fully grown in their size, but in 3-4 years the buildings of Metrodom Panorama will be covered with especially lush vegetation.

‘Odla i stan’ aims to spread and develop urban farming in a long-term and sustainable manner with residents, associations, property owners and city administrations. The company also works with educational farming at schools and in Malmö Museums (Malmö Museer). Furthermore, “urban farming is an excellent method for increasing social community while providing self-produced food. ‘Odla i stan’ works to organize and coordinate organic farming in the urban environment.” This is done by only working with organic methods and trying to use only local resources.
