Flood protection

Park Track North (Park Spoor Noord) is built on a former railway territory and was aimed to provide a social, green and mobility 'corridor' as the territory disconnected parts of the city (Ref. 1,4). Now, the park has a sustainable drainage system, allows a maximum diversity of people to use the park and has trees that will last for a long time. The park is further considered sustainable because of the use of FSC wood, re-used materials and energy-efficient lighting while the historical railway elements are restored or reused (Ref. 1,7).

Wertach Vital is a project to reconstitute the Wertach river between the southern Augsburg limits and its confluence with the river Lech. Starting from the south, the flood protection has been improved, the depth of the river bottom has been halted, the river bed has been expanded and the banks have been upgraded as a recreational area. A major part of the measures has been completed. The project is supported by the Free State of Bavaria and the City of Augsburg, co-financed by the EU (Ref. 1).

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).

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).

Fobney Island in Reading (which is an area by the River Kennet in Berkshire county) was transformed through a restoration project in order to e.g. attract wildlife (birds; bats; water voles; otters). This partnership project (with work being carried out by the Environment Agency, Reading Borough Council, Thames Water and the Thames Rivers Restoration Trust), includes restoring the river and creating wetlands. (Ref. 1-3)

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).

The aim of ReWaM was to show ways how different forms of use of water bodies can be reconciled with their protection in order to sustainably maintain the diversity and efficiency of the different water ecosystems. This applies to both rural, suburban and urban regions (ref. 8). Increased sealing of urban surfaces and combined sewer systems for rain- and wastewater pose major challenges for urban water management. Therefore, the university of applied sciences and the city of Münster participated in a research project as one of three pilot cities running from 2015 to 2018 concerning improved rainwater management and the development of respective planning instruments. Several green roofs at the university campus were used as test spaces to explore and monitor rainwater infiltration efficiency and feasible green roof compositions. Also, different permeable surface coatings were tested at the urban depot (Ref. 1 and 4).

The entire neighbourhood area was calling for interventions, considering the conditions of decay of this part of the city. The initiative was requested by the residents of the area, in particular considering the state of plants and trees. What needs to be provided is a new surface of grass to replace the terrain on the ground to avoid problems of flooding and new plantations. The park has an important function in terms of mitigation of anthropogenic pressures, but also in terms of social value for the residents. (Ref.1.)

This NBS was implemented in 2012 in order to conserve the biodiversity in the natural protected area of the Cilieni Pond and in order to ensure the sustainable development of protected species. The Pond was declared a protected area and covers ​​47 hectares. First an evaluation plan of the current situation was created, followed by a management plan. Inventory of the flora and fauna was conducted and protection methods were implemented: cleaning the area and educating the citizens that have a daily contact with the pond. (1)

The Sand Motor is a hook-shaped peninsula that is artificially created at the coast near The Hague in order to protect the coast on the long-term. Not only provides the Sand Motor coastal protection, but it also allows for new forms of recreation and supports biodiversity as it creates habitat and allows for more varieties of species to live in the area. The Sand Motor is a unique pilot project in coastal management and follows the principle of 'building with nature' (1).
