Since 2007, in the area of a former tree nursery, the international garden in Bonn gives space for social integration. Covering 3,000 m2 the area was turned into an allotment garden with garden plots of approximately 40 m2. The plots are allocated to 25 families from different cultural backgrounds, living in the deprived neighbourhood of Bonn-Dransdorf to support their self-sufficient agricultural practices and foster their social integration (1,10). The aim of the project is to provide gardening families with the option for intercultural exchange and a chance to take roots in a new country. In 2003, the International Garden Bonn project was initiated is implemented by "Wissenschaftsladen Bonn", a community service group who persuaded the city of Bonn to provide the once city property free for this social inclusion project (1).

The restructuring of the main road Gran Via Fernando el Catolico has seen a rehabilitation of its green areas in two distinct plots: one occurring at its intersection with Calle Lagasca, and one at its intersection with Corona de Aragon. The intervention is connected to relieving the heat island effect that occurs in the city center, increase greenery with the planting of 114 new trees and making the main traffic artery more accessible and pleasant to pedestrians.

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)

"Grünes" C is an initiative of six municipalities (Alfter, Bonn, Bornheim, Niederkassel, Sankt Augustin and Troisdorf) to secure, connect and (re)develop open and recreational spaces (agricultural, cultivated, garden, commercial landscapes, protected nature areas, rivers, transport routes). The major objective is to create an accessible, united park landscape in the original area of the "Grünes C" which spans 37 square kilometres to preserve those landscapes facing urban pressure. This is envisioned through a set of interventions initiated in and around the participating municipalities. Bonn has three interventions that will be dealt with here (3,4,5,9)

The Urban Environment Observatory is located on a plot of 7,000 square meters of surface transformed into a garden with native vegetation. It is comprised by a library, an Assembly Hall, exposition rooms and spaces for educational activities. There was planned to be a cistern that would collect the rainwater that will serve for irrigation of the garden and the garden terraces (Ref. 1 and 7). The project has since been halted for what seems to be politically-relevant financial reasons, according to Ref 8:"everyone has many explanations to give about the current situation of an unfinished building after more than a five-year period".

This is a tree-planting initiative for the creation of a new forested area in the Parco Nord of Bologna. During the project lifetime (originally planned from2016-2018), a total of 4.000 new trees will be planted. The trees will be 2-2,5 meters high to give the appearance of a forested area inside the city (1).
As of 2019, the implementation of the forest is on hold and it depends on the construction of the so-called "Passante di Bologna", namely a highway with 3 high-speed routes. If the highway is approved (and there is enough funding) then the forest can also be implemented (6).

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).

Bjerkedalen is a recently constructed park around the Hovin creek in Bjerke District. It is situated in the middle of a settlement block, which used to have few public spaces. The park now acts as a recreational area with lots of green space, a river and several facilities for outdoor activities. The construction of Bjerkedalen park incorporated the installment of several important blue-green structures and features such as planting native trees and plants along the river, providing open grassy areas as well as reopening the Hovin river from underground pipes, with the aim of improved water quality and flood prevention.(Ref. 2)
