The Hachinger Brook is a natural water body, which level of water is highly influenced by groundwater. Due to the spatial expansion of Munich, sections of the brook were forced into concrete canals and pipes. The idea of restoring the brook into a quasi-natural state had already emerged in the committee of city panning in 1984. The city council of Munich decided in 2014 is to reconstruct the natural state on a 2,6 km stretch of the Hachinger Brook between Kampenwandstraße and Hüllgraben by excavating it and to turn it into a recreational area. In addition to the stream, the former village pond next to the stream is planned to be restored. (Reference 1) Trees and other vegetation will be planted alongside some sections of the brook. (Reference 1, 2). Because of the reluctance of the landowners on the proposed site of the intervention to accept a brook flowing through their property, in 2020, the implementation still hasn’t begun. (Reference 7)

In an effort to improve the Holásecká lakes for both recreation and local natural conditions, the revitalization project has modified areas on the shores of the Holásecké lakes reconstructed culverts between the lakes, and removed the panel which fortified the Opleta and Lávka lakes (Ref. 4). The largest restoration activity includes removal of mud from the lakes (which can be repurposed due to low contamination) for the sake of ecologically restoring the area (Ref. 4). Plans also include improving recreation by installing wooden piers and developing a paved footpath with benches (Ref. 1). The ecological restoration will be important for wildlife, especially birds and amphibians (Ref. 8).

A temporary new pocket park in Bishop Street. "Previously the plot had been boarded off since a 2009 fire led to a row of shops and takeaways being demolished. The park has been created to improve the derelict land on the corner of Bishop Street and Well Street before any future developments and is part of the second phase of city centre improvements following work which included transforming Broadgate and the station to Bull Yard link." (Ref. 1)

The project focuses on the development of a sustainable, social and ecological park that promotes citizen participation (ref. 2), which is one of the largest city parks in the Netherlands. It combines various blue-green infrastructure elements (ref. 1). The park includes recreational facilities, a butterfly garden and special constructions that provide habitat for species. The Máximapark runs largely on volunteers and the citizen participation is the outstanding character of the development of the park (ref. 2).

La Tiretaine is a river in Clermont-Ferrand which, in the past, was harnessed to run underground in order to address hygiene concerns and create more land for construction and industrial purposes (Ref. 5). Rehabilitation efforts have been made throughout the city in order to 'renature' the river. Efforts include the creation of a small park along the river near the school Saint-Alyre in 2008 (Ref. 1) as well as a vision to develop a park surrounding a section of the river by 2026 (Ref. 4).

The project was born with the idea of solving the huge debate around the creation of a city park that connects different parts of the city. The area close to the railway will be regenerated thanks to an above-ground park. This solution will allow to have a new green space in the city, and an additional panoramic view that will be experienced thanks to a new cycling path. In this way the whole area that surrounds the rails of the central station will be regenerated, providing at the same time an attempt to mend the urban and social fabric. (Ref.1.)

Isar River had been regulated at the end of the 19th century by forcing the river into a canal-type bed with embankments. This regulation made a negative impact on the flow velocity of the river, on its temperature balance, and increased the risk of flooding. The goal of the recent development was to restore the river's natural character on an 8-kilometre-long section of the river and to create a semi-natural riverside. (Reference 1, 2) This was considered especially important because the effects of climate change have already increased the frequency of heavy rain events and major floods. (Reference 3) The new concept leaves space for the river to shape and change its bed with every flood. Further aims of the project were to increase biodiversity and recreational quality.

The project “Un parco da vivere” (a park to live) within the regional natural park of Lama Balice underlines the social, economic and environmental potential of the place. The project aims at reactivate green spaces in the park and at the same time improving the accessibility for disabled people, through the creation of innovative practices such as sensorial and social gardening. This results in promoting the naturalistic value of the area, to improve the health of people and to enhance biodiversity preservation. (Ref.1.)

In 2016 the Municipality of Lisbon started the renovation of the Botanical Garden of Lisbon, declared in 2010 as a national heritage monument. The botanical garden is both a vital urban open space and a significant cultural landscape of the city. This Botanical Garden is home to an important collection of plants with economic value, reflecting the strong links to the Portuguese expansion and the routes of the navigators that spread them across the various continents. The intervention is expected to provide improvements in the irrigation and water circulation systems, in the rainwater harvesting system, in the reorganization and improvement of garden green spaces, and in the restoration of paths. With the objective of requalifying the space, bringing significant improvements in terms of sustainability of resources, visitors safety, new cultural and recreational opportunity spaces (Ref. 3, 4, 8).

The Côtes site is a natural space of 1300 hectares surrounded by the urban area of the Clermont-Ferrand area, between the cities of Clermont-Ferrand, Durtol, Nohanent, Blanzat and Cébazat. (Ref. 1). Its fragile biodiversity has required special attention from the city with several actions being taken to protect it from growing urbanization. Part of the site is a Natura 2000 area and the Clermont part of the overall site is designated a sensitive natural environment (ENS). A management plan was developed for the ENS and put in place for the years 2019-2024 (Ref. 12).
