The initiative aims to ensure open access to the river Regalica for the local community and to create a multifunctional recreational area there. Given current spatial development plans, the chosen location is the only feasible solution to facilitate public access to the river. The project will address multiple NBS domains as its plans include: building new water stand, fishing place, and an observation deck, developing an ecological and educational path along the riverside, developing recreational spaces for the community including outdoor and cultural activities. The project relates to the long-term brand strategy of the city: ‘Szczecin floating garden 2050’[1]. The architectural plan was accepted and put forward for the implementation in 2019; currently, in July 2020, the project is still in the planning phase [4].

The Green Bridge at the D2 motorway in Moravian Svätý Ján (Dúbrava locality) is a project under the Alpine Carpathian Corridor Project (ERDF). The project deals with biodiversity and is focused on building a safe and efficient passage for migrating animals over the D2 motorway connecting Bratislava and Brno (Czech Republic). The mountain ranges of the Alps and the Carpathians, which straddle the border of Austria and Slovakia, are the largest sources of biodiversity in Central Europe. The Corridor’s structure has created a forum for the managers of these regions to share ideas and develop solutions that can be applied within the entire region, instead of only per protected area. To ensure long-term continuity, key stakeholders are party to a Memorandum of Understanding that can contribute to sustainability in their area of responsibility. (1, 5, 6)

The Bohnenback Park project was one of the first urban redevelopment measures in Bielefeld and was opened its gates for the public in May 2017. The park is the combination of blue and green areas in the Bethel district. It was created by exposing the Bohnenbach stream which previously had been piped and been flowing underground. The park consists of free, bright spaces and lawns with few individual groups of trees. Along the naturally meandering course of the brook, there is a long, north-south oriented promenade, which also forms the backbone of the park. It separates the neighbouring buildings from a parking lot while also connects the Bethel district to its surrounding areas via a green corridor favourable for recreation (1, 7).

This project was implemented on the rooftop of a ten-floor building with a floor space of 1.4 hectares, with the implementation of a green roof of 650m2. The motivation behind this was to study the thermodynamic impact of a green roof in hot Athens. Results concluded that the greenroof significantly affected the thermal performance of the building. Energy savings of 50% were observed for air conditioning on the floor directly below the installation. In addition to the energy-saving benefits, the study also found increased biodiversity in the area. A plethora of birds and beneficial insects were observed on the roof, ranging from robin redbreasts, yellowhammers, yellow tits, coal tits, and sparrows to kestrels hovering high above eyeing up the smaller birds. Other species such as honey bees, tiger swallowtail, monarch butterflies, dragonflies and ladybugs were also seen (Ref 1). The study suggested in improved micro-climate and biodiversity of the constitution square (Ref 1, 6, 7).

Opened in 2019, the René-Dumont Park which runs adjacent to a railway is "a centerpiece of the urban composition of the Nouveau Saint-Roch neighborhood" in Montpellier. (Ref. 1 and 2). This north/south 1.2-1.3 ha vegetation corridor represents a major of the city's urban renewal plan and "allows a great articulation among existing habitats, infrastructures and a contemporary neighborhood" (Ref. 2). The large area is considered to be exceptional for dense urban centres (Ref. 2). "The Nouveau Saint-Roch district is an example of a social, generational and functional diversity" (Ref. 2).

The agriparc of the Mas Nouguier is an agricultural reserve entirely maintained by the city of Montpellier. Conducted in organic agriculture, the estate contributes to the preservation of the identity of the territory and to the valorization of the living environment. Accessible to all, it offers a beautiful walk in the middle of the vineyards. Apiaries are used to develop educational workshops and to collect honey with school children. Olive trees, centennial pines and a large meadow come to embellish this little bit of countryside in town (Ref. 1).

The current intervention involves restoration of Bohrova park in the city district of Petrzalka with the implementation of water conservation measures (9).

"Micro-flowering are participative urban gardening projects that allow the vegetation of streets by small plantations of annuals and perennials, vegetable and ornamental, in the municipal public space. Generally, it is a matter of developing a mineral surface on the municipal surface of the city by planting pockets. These are then maintained by the inhabitants who requested micro-flowering. Micro-flowering is a place of sharing and conviviality that allows the inhabitants to be actors of their neighborhood" (Ref. 1). In 2018, formalized 'greening permits' were launched. In this system, micro-flowering permits are requested by residents and "The municipal agents come to drill the concrete of the sidewalks and the City provides the plants" (Ref. 9 and 11).

Metrodom Panorama is a private investment containing four 17-storey residential buildings. Following the model of Bosco Verticale of Milan, the facades of the buildings will be created as vertical forests. In the balconies of the buildings 3 to 6 meter high trees are planned to be planted. The construction was finished and the buildings were opened for residents in 2020. As the building is still very new, the green elements of the building are not fully grown in their size, but in 3-4 years the buildings of Metrodom Panorama will be covered with especially lush vegetation.

The program aims to change gray urban courtyards into friendly places - the green oasis for neighborhood meetings and resting areas. Small project proposals developed by the housing associations for the revitalization/transformation of courtyards from all over the city compete for co-funding (up to 75%) from the city council. Many projects (over 86 by the year 2015) have been funded and implemented since the beginning of the initiative in 2008.(1)(2)
