Environmental quality

In 2019, the city of Poznań finalized works on another city park, as a part of its long-term urban redevelopment plan. When designing the park, the focus was on creating a place for relaxing and recreation for all residents - regardless of what forms of activity and relaxation they prefer. Therefore, the entire area has been divided into zones adapted to different needs, be it for active adults, children, or dog owners. The park comprises of an extensive lawn and is separated from a noisy street by a corridor of trees. Everything is lit with solar lamps [1,2,5].

The Jardin des Plantes represents a space rich in nature in the heart of the city and also hosts the Opera Theater of Saint-Etienne (Ref. 2). In 2015, "A thematic urban commission (with the citizens' district representatives) is set up to enhance the "Jardin des Plantes" while keeping its wild side but with a controlled vegetation." For instance, the social center proposed a fitness trail and elected representatives propose a signage of trees, the integration of design, thanks to urban furniture and ephemeral works" (Ref. 1). Citizens requested that vegetation of walls be undertaken to "avoid the flourish of unattractive tags" (Ref. 1).

Everton Park is one of the city’s precious green lungs, but it has been underused in the past. This area once housed a district of 60,000 people and was densely developed. In the 1980s, it was transformed into Everton Park (Reference 1).
The Everton Park Nature Garden is ¾ hectare walled garden located within Everton Park and is a well-kept treasure of wildlife and tranquillity. It is an established natural habitat that includes two small lakes, grassland meadows and woodland, rock types of interest to geologists and a heritage trail with guided walks available (Reference 1).
The project is part of the Nesta’s Rethinking Parks Programme which ran until 2015. It has a 1M pound national lottery funding that supported 11 separate pilot projects across the UK. The programme explored a variety of new business models to fund resource park services in the future. Everton Park is one of the pilot projects of Nesta. The Everton Park project was led by the Land Trust with Liverpool City Council and the Friends of Everton Park. The aim was to put in place a strategic plan for community management which will be part of a wider development plan for Everton to regenerate the area, provide new housing and, at the same time, secure the long-term future of the park. (Reference 2)

To increase the attractiveness of the area around the block of houses, the city of Poznań plans to plant an oak stand of about 50 trees (first and completed phase) and again 50 trees (second ongoing phase) in two designated plots. The planted greenery will serve as a natural noise barrier and offsetting for a concrete block of flats nearby [1,5].

“Zagreb for Me” was an ambitious and comprehensive project launched in 2015 by the Zagreb Society of
Architects in cooperation with the Faculty of Architecture at the University of Zagreb and the City of Zagreb.
The goal of the project was to start a revitalization of public spaces through the realization of 17 urban
interventions in the whole city area at the same time. This distributed approach aimed to improve the general
“image of the city” and raise the quality of urban life in segments of housing, recreation, leisure and social
cohesion and revitalization of Zagreb's public spaces using public participation as a tool. This project aims to decentralize designed public spaces and draw attention to some forgotten city spots. At the same time, the project, created from a “bottom-up” initiative, establishes a new model of public participation as well as new forms of collaboration (Ref 1, 2, 3). The project "Zagreb for me" was created on the basis of Acupuncture of the city - an interdisciplinary approach and public participation, but it covers a wider urban space, ie it deals with public spaces throughout Zagreb. After the conducted urban-architectural tenders for the selected solutions, the realization is planned. Only one urban-architectural tender was conducted and the implementation of the project stopped there, but the project "Zagreb for me" was recognized as an example of good practice with the possibility of application in other cities. (Ref 5)

"Pending the creation of housing and new walks by 2020, the association Carton Plein and the EPA (Public Building Institution) of Saint-Etienne have created a temporary public space on the site known as "la Cartonnerie". A place for exchange and conviviality, the site hosts artistic installations, ephemeral installations and events. It is a laboratory conducive to imagining new ways of doing the city" (Ref. 1). The citizens also created shared gardens in this area called "Le Jardin Experimental"(Experimental garden) (Ref. 4).

The Montreynaud Park is composed of a great diversity of spaces (dense woodlands, undergrowth, meadow spaces, small group of trees ) and presents a richness of fauna and flora. The challenge of rebuilding this area is to create a real urban park, a green lung that provides the junction between the upper and lower parts of the neighborhood and links it to the rest of the city. The redevelopment of the park must meet the needs of the inhabitants by developing a place of contemplation, pedestrian paths, sports and recreational paths, and in connection with scientific, technical and industrial culture (Ref.1).

This intervention is about the restoration of the riverbanks of the Janon River along a street in the Terrenoire District of Saint Etienne. This area was abandoned for more than 10 years, without maintenance and cleaning. Therefore, this intervention was mandatory for clean up to avoid flood as well as bringing back vegetation and offering some quality walking areas for citizens (Ref. 1).

There are various projects under the Den Grønne Kile initiative or the Green Wedge. The Green Wedge passes through all 4 subdivisions of the new district Aarhus K, and has a building percentage of 25% within the boundaries of the "wedge". (Ref. 3) Citizens are invited to contribute with green projects through the municipal innovation project "Green Citizen" (Grøn Medborger). (Ref. 1) The first and most prominent is a park created by citizens on an old railway track. The park has the nickname 'Kilen' and is a new city park for everyone, including upcoming residents and companies in the new district 'Aarhus K'. The park helps to promote the creative energy in the area and is in line with the development of the new district; it differs from the other city parks in Aarhus by offering space for many different activities and temporary projects that give life to 'Kilen' and make the trip along the railway track an exciting experience. (Ref. 1)

In 2012, the City of Lisbon has implemented a 2,5 km green corridor connecting Monsanto Forest Park ( 900ha) and the city centre through Eduardo VII Park. (1) It is a concept of continuous natural structure, consisting of a coordinated set of green spaces that intend to continuously bring the natural space to the interior of the city (ref.3)
This corridor is a fundamental part of the Ecological Structure, a matrix formed and articulated by systems: the Mobility System, the Water and Air Circulation System, the Fluvial-Estuarine Transition System and the Structural Ecological Units System.
