The Knowledge Mile Park initiative in Amsterdam aims to transform the long, busy and traffic-heavy street in downtown Amsterdam into an environment greener, more sustainable and more livable through the implementation on various Nature-based Solutions (9). Smaller projects include the creation and maintenance of pocket parks, green walls and facades, green roofs and living labs. The idea of the initiative came from the Knowledge Mile Community that aims at making Amsterdam more green, clean and smart by means of innovative solutions regarding air quality, climate change resilience, biodiversity and social cohesion. (1) municipality of Amsterdam and the business investment zone BIZ Knowledge Mile are working together with partners on the realization of the project (9)
The project is still ongoing, although parts of the Knowledge Mile Park are already created in 2016 including one living lab, two green roofs, a green canopy and a pocket park and other parts are planned such as the smart green wall (1)

The indoor green wall installed at the University of Natural Sciences in Lublin. Apart from its decorative and aesthetical functions, the wall will serve educational and research purposes. The wall consists entirely of moss and does not require watering. It will be monitored regularly to analyse the impact of light conditions for proper growth and development of plants in these type of installations [1,2].

The first external green wall in Lublin was installed at the University of Natural Sciences in September 2015, and it was later followed by two smaller installations inside and outside in 2017 [5]. Apart from their decorative and aesthetical functions, the walls serve educational and research purposes, as the suitability of the chosen plants for the Polish climate conditions will be evaluated for similar urban projects in the country. Finally, the project promotes urban greenery and certain offsetting for grey infrastructure [1, 2, 3, 5].

Monglong Park was rehabilitated in 2012 with the explicit aim of strengthening social ties. The site is a wooded area of 4 hectares to the south of the Bellefontaine district. Unknown until its redevelopment, it constitutes a true ecological niche for the city and has great biological richness and landscape. The associations of gardeners and the gardeners of the Bellefontaine neighborhood, including the Maghreb and Mong communities, were involved throughout the construction of the park (Ref. 2).

The Park Killesberg serves as the green centre of the newly constructed district in Stuttgart and continues the long history of the area as a garden show site with a contemporary expression of landscape architecture and as a model for interconnected green spaces. The design is the result of a collaborative process with the local authorities, citizens and neighbours (1).

Greened-over urban railway tracks (grass tracks) is a city-wide program in Stuttgart which assumes the construction of tram lines with grassed-over tracks. This applies not only to planning and construction but also long-term maintenance (ref 1).

A large urban park in Lublin was built to commemorate John Paul II’s visit to Poland in 1987. The project ensured the utmost possible preservation of the natural terrain so that it forms a harmonious whole with the surrounding landscape. The park serves as a green recreational area for the citizens with its open-air sports facilities and a small amphitheatre for local festivities and extracurricular activities [1].

The garden was designed by landscapers Michèle Orliac and Miquel Battle and realized for a cost of 3 million euros. This "new green lung", as presented by the City Hall of Toulouse, is part of a major urban project that provides for the creation of 500 housing units in the Niel District (Ref. 1). The project involved creating vegetation enmeshed benches (Ref. 7) and using permeable flooring materials that prevent water loss and reduce the potential of flooding (Ref. 8).

The construction of a new main bus station inaugurated in 2014, is part of a desire to reduce greenhouse gas emissions and to encourage users to favor bus routes (Ref. 1). Part of this construction project, a vegetal wall of 210 meters long and 8 meters high has been implemented in order to act on noise (-20 decibels) and visual pollution, and improve air quality. It will be the largest public vegetal wall in France. (Ref. 4, page 26)

Derelict flats are replaced by an oasis (including flowers and fine art) on the Aysgarth estate, creating a "long-waited community haven". A community garden was officially opened to "create an area of much-needed green space". (Ref. 1) The project aimed to create a garden that the whole community could enjoy. (Ref. 1)
