Increased conservation or restoration of ecosystems

The Brackwede open-air pools have been a significant landmark of the city of Bielefeld and part of locals' life since 1926. After several renovations since its opening, in 2005, the maintaining company of the Brackwede open-air pools proposed to convert the pools into natural-water bodies through the application of natural water filtration systems. The pools are supplied from the natural underground stream of Ems-Lutter whose spring water is physically and biologically purified by natural mineral soil filter and water plants. Chlorine is prohibited in this pool - the nature itself ensures water quality (1). Since 2009, the Natural pool of Brackwede offers natural facilities for swimming and other water-related activities besides cultural, sport and recreational opportunities for all (1).

On the derelict industrial plant in Brackwede, which was independent until 1973, a large leisure facility with an extensive range of leisure activities was planned. However, due to more recent findings, this direction was rejected and a natural green corridor was created with unique biotope areas that had developed over time from the abandoned bleaching ponds and meadows. The Luttertal is located in Bielefeld Quelle, south of the
The industrial plant in Brackwede was intentionally abandoned since 1973, due to the local municipality recently cancelled the project of the redevelopment of the area and kept it intact. Till now, a “natural green area developed with very interesting biotope areas, which had evolved over time” at the abandoned site.

The lagoon has a great local significance for its biodiversity with the presence of certain species of rare birds regularly stationed in this area. Much of the biotope was degraded in the last decade by systematic embankments, constructions, as well as the inconvenience caused by various man-made pressures. A project was developed to reconstruct the area within the framework of a collaboration of the Institute of Marine Biological Resources, Inland Waters of HCMR, and Hellenic Ornology Company. The project offers directions for completing a protected region and proposes specific projects and actions of scientific monitoring, ecological rehabilitation, regeneration, and promotion. (Ref 3)

“An integrated solution for groundwater, rainwater, waste water, streams and ponds creates attractive housing in a new suburb (NyE), with room for exciting architecture. The water cycle plays a key role in urban development in Denmark, and water is one of the ever-present elements in our lives. Århus needs to prevent flooding caused by climate change, avoid polluting our groundwater, and improve the environment in streams and ponds to allow the use of water to create recreational value for the residents. This way, Århus can build a balanced aquatic environment, which will ultimately create a better city.” (Ref. 1)

The establishment of the first stage consisting of 650 homes, day care center and grocery store was initiated in the autumn of 2016 after more than 10 years of planning, and in the summer of 2018, the first residents moved into Nye. More homes are on the way. (Ref 14). In its current form of just over 150 ha, it has a capacity of approx. 15,000-20,000 inhabitants or approx. 10,000 homes at full expansion (Ref 15)

The botanical garden of Athens was reconstructed in 2004 to protect and maintain the biodiversity of the area. Covering a land of 1,860 sq.m., this Botanical Garden hosts over 2,500 different kinds of plants from all over the world and a rich variety of flora. All the plants and trees are protected in the park. The community also sends seeds all over the country to spread and maintain biodiversity throughout the region and hold agroecological events to increase the concern and educate the locals (Ref 1,3). The park also has a lake and a library inside it. (Ref 2)

The project primarily aimed to replace the largely underused 2-hectare public green space, Chavasse Park by creating a new public park that forms the centrepiece of the Liverpool One development.
The park, designed under the collaboration of BDP and Architect Pelli Clarke Pelli, was envisioned to become a green oasis within the city centre, with the ability to accommodate a lively programme of outdoor events (Reference 1). It comprises a ‘Grand Lawn’, richly planted terraced and walled gardens, sites for beautiful pavilion buildings, sheltered seating, trees, planting and multifunctional paving areas (Reference 2). Chavasse Park was awarded Green Flag status and is home to a nature trail and a unique species - Speckled Bush Cricket. The Park is home to more than 150 species of insects, birds and animals (Reference 4)

The intervention included the renovation of lake Jarun and its surrounded park and recreational centre. Efforts were made to improve the amenities at the lake and park in order to bring it closer to the citizens, particularly to disadvantaged groups. It provides facilities for walking, bicycling, various outdoor sports, trim-track of 6500 meters of length, roller skating, etc. Sports facilities are related to an impressive 2250 meters long regatta path where international and world rowing, canoe and kayak contests are held. With daily training and performances, they give Jarun a special, sporting atmosphere (Ref 1, 2, 3, 4).

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)

In 2002, the facilities of the Bielefeld Botanic Garden was expanded with a small apiary for local bees. The apiary was opened on the 90th anniversary of the Botanical Garden and since then in its 5 beehives accommodate the bees living in the garden. The facility is a place for breeding of bees to support their pollination activities and thus their role in food production while the apiary also offers visitors the chance to get an insight into the life and work of a beehive. Through various environmental educational programs, visitors and school children can learn about the importance of bees and the process of honey making. Beekeeping stations were also installed in other surrounding areas such as cemeteries, old dumps, fenced rainwater retention basins. (1,2,3,4)

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)
