Ecological restoration of ecosystems

The Bahlui river was prone to floods especially during spring and autumn and as a result of the fact that for almost 40 years there has been no work for the decolouration and sanitation of the river and the industrial enterprises in the county have discharged polluting substances in water (mainly nitrogen and phosphates), Bahlu River has become a polluted river. In addition, some citizens of Iaşi have discarded waste in its bed (especially in peripheral areas). In 2011, a larger project funded by the EU, implemented the regularization of the river. (1)

The Institute of Landschaft and Freiraum together with Grün Stadt Zürich and ETH Zürich is developing a project on how plant biodiversity in the city of Zurich can be maintained through urban ecological design. In collaboration with the University of Lausanne, they will assess fragmentation effects on the species, functional and genetic diversity of wildflower patches, and, more specifically, on the population viability, evolutionary potential and connectivity of selected model species. These results will feed directly into the biodiversity programme at Zurich’s office of parks and open spaces (Grün Stadt Zürich). (Ref 1)

The NBS includes the establishment of a new country park, Elba Park, with the goal to create a haven for wildlife and a space for people to enjoy nature. 52 hectares of former coal-mined were transformed under the management of Groundwork NE (Ref 2 & 3).

The project regards the creation of a natural park close to the Orteto river, which crosses the city of Palermo. The problems of the area mainly concern the housing development, which was increasing during the years without considering the potential negative environmental impact. The creation of the park is expected to be a solution to face the challenges created by the unsustainable development of the area. It would be an opportunity to regenerate an area where intervention is needed, providing additional ecosystem services such as coastal protection, and improving air quality. (Ref.1.)

Bee-friendly Nottingham is a campaign run by Nottingham City Council to make Nottingham a more pollinator-friendly city, promote pollinator-friendly gardening at council events and to protect bee populations by planting pollinator-friendly plants via planting schemes (Ref. 1). It aims to make some lasting changes to the way people manage open spaces in order to help wild and domestic bees and provide more flowers for foraging and more habitat for nest sites (ref. 1).

The Rohrschollen island, located near Strasbourg, is representative of a particular environment in Europe: the Rhine alluvial forests. These forests are known for the exuberance of their vegetation and their richness of species: it is a rare ecosystem both at the national and European level. These forests are regressing nowadays and as a result, the four major European rivers from the Alpine range (Rhine, Rhone, Danube, Po) have lost most of their riparian forests. The objective of the project is to restore a dynamic flood regime on the island of Rohrschollen that is modeled on the Rhine's hydrological rhythm (Ref. 1).

The Development of the Garden of the Schloessel project is part of the Natural Urban Park project undertaken by the City Council in consultation with the Strasbourg Urban Community (Ref. 3). The project aims to reduce the carbon footprint of the area by installing and redeveloping green spaces in the garden as well as providing the site with stormwater management infiltration (Ref. 1).

The project of the Park of Malaga was to rehabilitate the lateral spaces of the Paseo del Parque, the organization of the environment, the recovery of the flora and structure of the Park, as well to construct a solution for problems of mobility. (Ref. 1). Recovery of Vegetation of the park, its original layout, and its scientific character of garden Botanical and species acclimatization were central aims of the project (Ref 1).

Wildlife in the City is a project led by Nottinghamshire Wildlife Trust, with Nottingham City Council, to promote, protect and celebrate the nature reserves, wildlife sites and green spaces across Nottingham City (ref. 2). Wildlife in the City is a project run by Nottinghamshire Wildlife Trust was originally designed to raise awareness of the value of urban wildlife and to inspire people to get involved with caring for wildlife sites on their doorstep. The project aimed to engage people in their local green spaces and wildlife. Wildlife in the City ran lots of activities and events, volunteering opportunities, training opportunities and more (ref. 1). It began as a three-year project funded by Natural England through Access to Nature, as part of the Big Lottery Fund's Changing Spaces programme. The project worked with local people to undertake vital habitat creation and management works throughout the city. It particularly worked in areas of Nottingham with previously little wildlife activity from the partners. These areas were Bestwood, Bulwell, Aspley/Broxtowe estate, Clifton, The Meadows, and Sneinton (ref. 6). After the funding for the project has ended, its objectives and the partnership between the City Council and Nottinghamshire Wildlife Trust remained and the Trust continues managing many of the Council's wildlife sites and using local volunteers to help out with essential tasks such as scrub management, gardening, litter picks and floral surveys (ref 2).

Landscape Park Neckar is a multi-place NBS intervention that is being realized along the banks of the river Neckar in 27 cities, including Stuttgart. Along the river axis, the free spaces between the dwelling buildings, industrial areas, and transport terminals are identified to be transformed into green areas, parks, and new recreational facilities. With this step-by-step approach, it succeeds in regenerating green areas for natural and social functions and helps drawing attention to the diverse benefits of Green Infrastructure. There are now eight master plans for the different landscape areas, which fit together like pieces of a puzzle to form the Stuttgart Region Landscape Park. Each sub-concept is tailored to the characteristic conditions. Since 2005 the Verband Region Stuttgart has been calling on cities and municipalities to submit project ideas. From this, the projects are selected in a competition in which the region pays up to 50 per cent of the costs. In this way, total investments in the Stuttgart Region Landscape Park of around 45 million euros have been triggered in recent years and around 200 projects have been co-financed by the region. The redevelopment of the landscape is in the ongoing phase. (ref. 1, 2, 7).
