Previous derelict area

With the "Green River" for Milan, the design team coordinated by Stefano Boeri has proposed an urban reforestation project that aims to realise on 90% of the seven abandoned railways a continuous system of parks, woods, oases, orchards and gardens for public use, linked between them by green corridors and bicycles made on the railroad tracks. (1, 3 and 4).

This project focuses on the development of environmental regulations stimulating the connection of existing green areas and developing new ones in the urban area of Rome to stimulate biodiversity by rehabilitating 73% of free/derelict areas. This was done to guarantee an integrated protection of already existing areas as well as restoration of green and blue landscapes (1). The Ecologic Network is still ongoing and provides specific limitations to any new infrastructural project to make sure specific environmental standards are respected (3).

This is a project financed by the EU LIFE Project on CO2 sequestration and reduction levels in the urban area of Rome. One of the initiatives involved an NBS, as RomaNatura took care of planting new trees over 2 hectares of land in the Valle dei Casali in the Municipio XV area (Ref. 1).

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).

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).

San Giuliano Park, inaugurated in May 2004, was designed by Arch. Antonio Di Mambro of the Comunitas Group. The first two lots have been implemented for a total area of about 74 hectares, including green areas and recreational infrastructure. The creation of this park is one of the biggest re-qualification initiatives in the national territory. With the implementation of the park, the area of Punta San Giuliano, used for years as a landfill of industrial and urban waste, definitively loses its barrier function between Mestre and its lagoon and returns to the natural state of the ancient city (1).

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).

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).

”Gothenburg is now greener and more beautiful. Urban farming is the name of the investment that Göteborgs Stads Fastighetskontor (The property office) makes to stimulate small-scale and residential/urban farming. The goal is to get new crops, crops in unconventional places, plants/farming that provide joy and help to spread knowledge and create contact between generations and people from different parts of the city and the world. But also to develop the already existing cultivation and colony areas.” (Ref. 1)

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).
