A 5km section green corridor in the province of Malaga. The initial intervention was planned and opened in 2015, converting non-operational train tracks into a green path for pedestrian and cyclist use. (ref 1,4). The whole corridor will unite the Natural Site of the Desfiladero de los Gaitanes with the natural site of the mouth of the Guadalhorce river. (ref 3)

Since October 2015, the City of Marseille has implemented a vegetation permit called "Visa Vert" (Green Visa), as well as a "Charter for the vegetation of public spaces in Marseille", which allow individuals to install plants in public spaces
while respecting the safety and use of the tracks by other users. Plants, flowers and shrubs can thus contribute to the beautification of the living environment and "bring a bit of nature into the city" (Ref. 1). The charter aims to “ accompany and support initiatives to revegetate the streets and promote collective actions that contribute to embellishing the living environment ”, but also to “ enhance the presence of plants in the city, to respect the public space which belongs to all and thus to improve living together ” (Ref. 5).

This intervention involved the realignment and merging of St. Mary's Way and Livingstone road into "St. Mary's Way Boulevard" of which a sustainable urban drainage (SUD) system is a key component. It consists of 31 large specimen trees that are planted in soil cells. The purpose of this project was to improve pedestrian accessibility, attract net investors, and to enhance the water drainage system (Ref 1).

Funded by the ERDF through the financial instrument JESSICA, the aim of the ecopark is to compensate for the tree felling during the construction of the second rowing canal by the river Maritsa, provide a natural place for recreation, and restore the ecological stability of the area. This is accomplished by restoring elements of the natural habitat in the river and the land nearby: trees, terrestrial and water plants, and small islands.

The biotope Schladitz is the regenerated remains of a former installation for the dehydration of sewage sludge implemented in 1952 by the communal waterworks company which used to pump its sewage sludge into the municipality of Rackwitz North of Leipzig. Upon its termination (1990), the company conducted large regeneration works of the contaminated sites from 1991 until 2011. The area was renaturalized, a biotope was implemented with plants species to retain the toxic substances. Now the area is also used for nature experience, observation and environmental education for children and adults (4, 7).

The intervention will be carried out in the Zen neighbourhood, as part of an overarching project which includes the care of green areas and plantation of new trees in the parks, especially those close to public schools. There will be 11 specific areas of intervention within the Zen neighbourhood. In addition, it is underlined the specific service provided by those new areas, such as the positive impact of the green view, the mitigation of effects such as urban pollution and human impact on the environment. (Ref.1.)

Allotment gardens have a long tradition in Hannover, with approximately 20.000 gardens stretching around the city as a green belt. In the last decades, some gardens were threatened by disappearance due to investment interests (Reference 1). With the goal to protect these gardens, the city employed a so-called "Kleingartenkonzept" (allotment concept) in 2016 with the help of the association of allotment gardens (Bezirksverband Hannover der Kleingärtner e.V.). The concept aims to keep the number of existing gardens for social and ecological considerations while allowing for new residential investments which is vital for the growing city. (Reference 2).
As part of the concept, extensive inventory examinations were conducted on areas affected by conversion and restructuring, along with the start of implementation of smaller development projects for housing and the creation of replacement gardens in some areas. Because the need for residential spaces has been covered for until the end of 2019, the conversion of allotments for the said land use has been stopped; it will be revisited in 2024. (Reference 2)
To address the problem of future allotment garden losses, gradual elimination of permanent vacancies has started by creating new smaller and more attractive gardens from oversized ones, by improving accessibility and optimizing spaces, and by modernizing allotments (Reference 2).

The project involves the formation of a statutory Green Belt of 3,500 hectares as part of the broad strategy of the Tyne & Wear County Structure Plan to restrain the further spread of the built environment and to safeguard the city's countryside from encroachment (Ref 2). The Green Belt prevents small villages to merge with large towns, preserving their individual identities, and also accommodates a wide variety of the borough's environmental assets, including Local Wildlife Sites and wildlife corridors (ref 3). It is claimed to contribute significantly to the city's green infrastructure (Ref 1 & 4).
The Green Belt boundaries have not changed since 1998 (Ref 1), but it is currently (in 2020) under reassessment in response to the development needs of adjacent towns (Ref 1). Thus even though the intervention started almost 50 years ago, it is an ongoing process.

The project RUIS (Riqualificazone Urbana Infrastrutture e Sicurezza), stands for the regeneration of urban infrastructure and safety. The initiative is carried out by the municipality of Palermo, in order to improve the urban resiliency of the intervention area, with the creation of further green areas in neighbourhoods dealing with problems of heatwaves and environmental degradation. The main areas which will be the focus of the regeneration process will be those considered to be in degradation state. It is expected that the quality of life of the residents will significantly improve (Ref.1.).

The Belvoirpark has its origins in the 19th century and is one of the oldest landscaped gardens in the region. Set on a beautiful location close to the lake with views of the city and the mountains, the Belvoirpark has retained its specific topography with large level differences and exotic trees. Since the twenties, Gastrosuisse operates here a Hotel Management School with an upscale, publicly accessible restaurant. The former school building was spatially and functionally not integrated into the parkA huge transformation of the Belvoirpark area was done to make the park more green from 2004 – 2015. The transformation of the area around the new construction of the replacement building allowed a reappraisal of the previous situation. (Ref 1)
