Rehabilitate and restore damaged or destroyed ecosystems

Bundek Park is one of the urban planning projects aimed to create a recreational and sports area for the citizens and tourists to support a healthy lifestyle (Ref 3). The lake is surrounded by Bundek Park which stretches for 2,000 meters in length with an area of 35 hectares. The lake is about 5 hectares. the lake was initially used for fishing, walking and swimming. With the increased and carefree use of the lake, the lake and the environment became a waste disposal site. In 2005, by the decision of the Mayor, Mr. Milan Bandić, the renovation of Bundek began. The project included cleaning of the informal waste disposal site and shrubs blocking access to the lakes, renovation of the access to the lakes, planting flowers and introduction of the benches and water also to allow citizens to use the lake for recreation and enjoy the nature (Ref 2).

The El Patriarca Park aims to rehabilitate and restore 60 hectares of land for ecological benefits and recreational purposes for the inhabitants of Cordoba (Ref.1,3,4,6). It takes place on a site with distinct areas, including a holm-oak forest with Mediterranean scrubland of extraordinary environmental value. This NBS is an effort to protect natural values, erase the traces of urbanization attempts of the seventies, and repair damages caused by human action (Ref. 6). Implementation of the project is expected to start in early 2021 (Ref. 6).

The project is part of the Environmental Billion project (of the City of Stockholm). The aim is to increase biodiversity, mainly linked to the landscape and also to increase the accessibility for visitors to the Kräppladalen (which is also known as Rågsved’s recreation/outdoors area) and make it more of an attractive area to visit. Also, the project aims to develop a programme and work documents that show how the purpose is to be achieved and also to perform restoration and accessibility measures in accordance with these documents. (Ref 1, 2)
Rågsved's nature reserve is the city's latest reserve and was inaugurated in 2018. It contains a mosaic of open meadows, wetlands, moist deciduous forests, deciduous environments and coniferous forests. (Ref. 7)

A recovered green area next to the Guadaira river, it opened as a park in 2014 (Ref 6). In its planning it reconciles the historical use of the river to power the historic mill and its new use as a green corridor on the Eastern part of the city. Its large dimension allows it to fulfill the quadruple ecological, landscape, leisure, and non-motorized mobility dimensions. (Ref 4,5,6). The park was officially inaugurated but it continues to face challenges. In 2007 the economic crisis led to construction being stopped and the budget of the park cut from 23.8 million euro. Construction was started and the budget re-established at 17.2 million in 2011. (Ref 5)

“The park, inaugurated in May 2003, [was] part of a 1990s project aimed at recovering the ancient canal, combining social needs and providing a space for citizens to spend their free time.” (Ref. 7) It is located on the south bank of the Guadalquivir river (Ref. 7), and today serves as a space for “leisure, sports, and intergenerational coexistence” (Ref. 1)

“The Guadalquivir River offers some of the best landscape, ecological and environmental values. There is an exceptional variety of flora and fauna and the river is considered as one of the main lungs of the city and as a privileged area for the residents”. (Ref. 12) The river is an essential element of Cordoba, having been declared a natural monument in 2001. (Ref 3, p.4) There are ongoing efforts to maintain and restore the river as a natural and cultural heritage site (Ref. 1,2,5,8,9) and a space for recreational activities (Ref. 12).

Oslo municipality is underway with the large-scale project of opening up rivers that previously were running in underground pipes. Alna Environmental Park is a part of this project and includes major transformation and environmental upgrade of the river Alna. The Environmental Park runs along the river and has transformed grey structures to accessible parks and recreation areas and now acts as an important resource for Oslo's citizens. Central aims of the project are to improve the self-cleaning ability of Alna, while maintaining biodiversity in the region and to inspire future urban development. (Ref. 1, 3)
