The largest rain gardens in Sweden (thus far) has been created in Göteborg (Kviberg park). Kviberg's multisport arena was completed in the summer of 2015 in the northeastern part of Göteborg. Around the facility, there are parking spaces with a capacity for 500 cars. In order to handle the rainwater flowing from the parking area, approximately five per cent of the total area has been used for rain gardens, which both clean and store the rainwater. (Ref. 1, 2)

Sweden's largest real estate company, Vasakronan, tests its first green outdoor facade at Kyrkogatan in Göteborg. The project was implemented with aim of improving the local climate and contributing to a more sustainable and resilient city. (Ref. 1)

These gardens fulfil several purposes and have become more and more often a point of aggregation and leisure, of socialisation and recreation, didactic and cultural education. Two interventions were made and in 1991, where 36 and 48 ornamental plants were produced. Subsequently, the gardens were built in the PEEP area of ​​Zelarino (in 1997), and in via Pertini (in 2002) and thanks to the environmental context and the available space, an element of novelty is introduced: the gathering area for communities to share environmental common values and activities. (2).

The project opts for switching to more sustainable and organic ways of handling natural parks in the urban areas of the city of Bologna. The project was launched in 2008 and focused on 100 hectares, meaning 10 parks (out of the 1.100 total in the city). The goal is to develop maintenance techniques with low impact on local flora and fauna, stimulating biodiversity and an equilibrium with the surrounding urban environment, as well as the reduction of toxicity impacts for vulnerable residents (i.e. children and elderly people) (1 and 2).
This NBS solution focuses on changing maintenance of Bologna public urban parks from conventional techniques to biological ones (1 and 2).

The project aimed to make the banks of the river Sava a more secure place by setting up illumination poles and thus motivate people to go there also by installing potable water fountains. The project includes environmental friendly illumination of both sides of the river Sava, development of 6 water pipes and toilets and renovation of the pedestrian and bike paths (4 sq km). The project in the second phase will also include additional illumination and water stations up to Jankomirski Bridge (in total 16 km, on both sides of the river Sava) (Ref 1).
The locals use the area for running, dog walking and for relaxation. Previously the place didn't have lights which made it unsafe during the night. The Mayor promised the citizens to return the river as well as an emphasis on the bridges that "conect, rather than separate" (Ref 1, 2, 3, 4).

This is a pilot project part of the strategic plan "Città di Città" in the Milano province, launched in 2006 by the Direzione Centrale Risorse Ambientali, by the Parco Agricolo Sud Milano and by the Multiplicity.lab of the Politecnico di Milano. The project consists in the realisation of a green ring surrounding the city for an extension of 30.000 hectares (15% of the metropolitan area). The ring will connect a series of green areas already existing in the city. The project will insert a total of 3 million new trees along different areas of the city (2). The "metrobosco" is described as: a green belt made up of new forests, parks and rows that extend along the borders of the capital of Milan. A continuous ring of trees and small and large clearings to meet farms, abbeys, watercourses, agricultural areas and spaces for recreation and sports. The project arises from the need to redefine the relationship between city and country, to intensify plant and animal biodiversity, the preservation of existing and the construction of new "ecological corridors", the mitigation of climate imbalances, the abatement of noise and atmospheric pollution, the care and maintenance of the territory and the production of sources for agro-energies (4).

On a yearly basis, the city of Zagreb, Zagrebački holding plants new trees and bushes to maintain Zagreb as a green city with 114 hectares of green spaces (Ref 2). Also includes maintenance of green surfaces, such as grass in public parks along with tram tracks and planting new trees and maintaining existing ones next to kindergartens and schools (Ref 2). Maintenance of city parks, lawns and tree lines includes cleaning, mowing and collecting grass and garbage from green areas, restoration of trampled lawns, maintenance and pruning of trees, shrubs and hedges, maintenance and care of seasonal and permanent flower beds, maintenance of paved and dune areas in parks and installation and maintenance of urban equipment in parks and children's playgrounds (Ref 1).

The Alicante City Council will receive 11 million euros from the European FEDER sustainable growth program 2014-2020 to carry out this project, the Integrated Sustainable Urban Development Strategy of Alicante DUSI Las Cigarreras. This funding will allow the integral transformation of an area that extends between The Castles of Santa Bárbara and San Fernando.” (Ref. 1). The specific transformation includes the recovery and dynamization of an important urban area that includes four historical neighbourhoods and two of the most emblematic mountains of the city, surrounded by two castles and with extensive green areas and rehabilitation of the existing city from the social and environmental sustainability, facing new urban development (Ref. 2)

2017 Green and Grand City is part of Göteborg's 400th anniversary (in 2021), and plans are developed up to the anniversary on a yearly basis. In 2017, the focus was on a greener and grander Göteborg. The vision for 2021 includes three themes, water, building bridges (reduces divides between people) and open spaces. The anniversary efforts build on three elements of sustainability; social, ecological and economic. (Ref. 1)

The city of Zagreb prepared city-owned land on 10 locations for urban gardening, called "city gardens" for citizens who do not own land in Zagreb. The project "City Gardens" is a positive example of sustainable use of urban land and improving the quality of life of our citizens in social, economic and environmental terms. City gardens provide access to healthy food and improve the household budget of citizens, contribute to preserving a healthier environment, preserving biodiversity, environmental awareness of citizens, connecting with nature, healthy leisure and promoting a healthy lifestyle and developing partnerships between the City of Zagreb and citizens (Ref 1).
