Garden at the Observatory of Urban Environment
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".
New Urban Woods in the Parco Nord
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).

Bio-Habitat
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).

Metrobosco Project
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).
Las Moreras Orchard
Recreation and Educational orchards were created as part of the Miraflores Park interventions and rehabilitation. These orchards were available for public use and had educational programs where the children would learn and cultivate the land. The Orchards were formed of four separate programs: Huertos Escolares (School Orchards), Huertos de Ocio (Leisure Orchards), Educational Itineraries, and Youth Greenhouse. (Ref 4)
Green Campus at the Zagreb University
The project involved the redevelopment of old military infrastructure at the periphery of the Zagreb city (Boronaj) into a green and carbon-negative university campus. The Boronaj campus has planned to be the green campus of the university and includes the use of renewable energy (biomass, geothermal and solar), treatment cell for wastewater and a huge green area (with trees and shrubs). The buildings (constructed and to be constructed) are planned to be carbon negative (Ref 1). A significant portion of the campus is the green areas (with trees and shrubs). This was created with the aim to contribute and maintain the native species diversity (Ref 3, 4). In addition to increasing the biodiversity of the city, the tree species has improved the air quality of the area and reduced the local air temperature. The project is partially completed. Some buildings are yet to be constructed. The Campus was officially opened on October 12th 2007 and for now, it hosts 4 university units: Centre for Croatian Studies, Faculty of Education and Rehabilitation, Faculty of Traffic Engineering and Faculty of Economics and Business (only vocational study programmes in economics and business). Five other faculties are also planning to relocate to the Campus in the next few years. Besides the (re)construction of university buildings, campus will be home to a sports centre, student residence hall and a number of institutes. The project is partially completed, some of the buildings are completed while some are yet to be constructed. (Ref 1, 3, 7).
Planting native trees along the highway
In 2010, about 300 people participated in the planting program for the “350” project and under the “Verde por el Clima” program (Green for the climate) organized by the Department of Environment, Cordoba city council (Concejalía de Medio Ambiente). (Ref. 3)
Villa Bernaroli: peri-urban rural park
The project addresses a current issue: the integration between cities and the countryside, and the relationship between the urban and the agricultural context. The NBS focuses on enhancing the west peri-urban area of Bologna through the promotion, recovery and valorisation of old rural settlements as new nodes of the productive-fruit network (4). The intervention is extended over 50 ha of municipal property and focuses on natural restoration of the rural landscape and the infrastructure in proximity of it in order to improve local agricultural businesses and recreational activities. As of July 2020, the project is still in full force.
Open spaces 2010: landscape preservation
The conservation of agricultural activities allows for the preservation of the landscape for all, with the possibility to offer to Milaners a place of leisure, tranquility, nature and tradition within the city, where to taste - also while tasting the products of the earth - what is the the Milanese agricultural world. It is located in the South West of Milan, within the Parco Agricolo Sud, in an area between the two Navigli, the Grande and the Pavese (1).
Green Roofs for Sustainable Water Management
This project was the first green roof in the city of Bologna, and it has been carried out by the University of Bologna in collaboration with the Columbia University of New York with the aim to prove more evidence on green roof stormwater performance. For the Engineering School of Bologna University the existing roofs had a load capacity that was able to host only an extensive roof, without the costly need of being reinforced. In the extensive roof type the vegetation is usually very drought resistant and plants can adapt to difficult environmental conditions, therefore sedum was chosen (1).
