The innovation is transferred to new initiative(s) without substantial adaptation

The Vertical Garden Wall situated at the J&T Bank Café Bratislava was constructed in 2010 as Bratislava's first vertical green wall. The green wall in the two-story J & T Bank Café is one of the most recent implementations of Patrick Blanc – botanist and the creator of Vertical Garden. The Café was designed by the architectural studio MIMOLIMIT, and has been realized under the supervision of AED project. The vertical garden consists of more than 2600 plants of 66 various species (3).

A formerly derelict area, part of a 19th-century estate, the Zurich Square is a park, whose whereabouts are relatively new, and whose main function is to serve as the only park for the 700 children of the neighbourhood. Its location makes it also valuable, meaning that this park is situated in an industrial area and it contains trees planted in the 19th century (1).

The OrtoCollettivo project focuses on the creation of common spaces to grow local sustainable food while raising awareness about environmental challenges in cities. The project is based on teamwork: if there is work planned for today and someone cannot come to do that job, someone else will do it, with the ultimate benefit of everyone. It, therefore, stimulates common values about well-being, sustainable food production, and sharing time and activities collectively as a group (2). The initiative is ongoing and expanding, however in 2020 there were voices from the people living in the area that the poor maintenance of the terraces caused landslides and disturbed traffic. Nevertheless the NGO that initiated the intervention defended the project and suggested that the issue is caused by the lack of canals for the rain water to flow in. (8)

Lisbon's Biodiversity Route is a pedestrian route of 14 km, marked according to the norms of the Portuguese Federation of Camping and Mountaineering. It connects the Forest Park of Monsanto to the Tejo river, which aims to contribute to raising the awareness of the value of the city's biodiversity (ref. 4). The position and dimension of these connected areas important in relation to the climate regulation, air quality and for the diversity of habitats that the city offers. The Biodiversity Route is a circular route, which can be done on foot or by bicycle where each species of fauna and flora that can be observed (Ref.1).

The Leonardo Garden was a community garden in an empty building site of 8th district of Budapest, that implementation was initiated by KÉK, the Contemporary Architectural Centre. (Reference 3)
The recultivation of two neglected, empty plots of land created one of the earliest community gardens in Hungary. Plants for consumption, spices, herbs and ornamental plants were planted. The 95 plots in the Garden were cultivated by young people, families and pensioners, but the Garden also served educational purposes, as it frequently received school groups. The Garden has hosted a number of public community and cultural, gastronomic and musical events, which were well attended by both the neighbourhood and the general public. The community garden was closed in March 2018 because the company that owns the land wanted to start construction on it. (Reference 5)

An indoor vertical garden by a French botanist Patrick Blanc installed at the Headquarters office of the InternetSupport company in Bielefeld. The garden cleans the air and serves the aesthetic function of being an interior decoration (1).

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)

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).

"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).

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)
