Transformation of previously derelict areas

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).

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 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)

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).

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).

Due to years of under-investment left the Park Hill estate in a state of decline. The challenge for Sheffield Council was to regenerate a neglected estate into a place people wanted to live in. The city council allocated private gardens, a wildflower meadow, a bowling green and a parterre garden as part of the landscaping. Much of the landscaping will be inspired by the Peak District and typical Sheffield landscapes (ref 1). Park Hill is Grade II (special interest buildings and authority put extra effort to preserve them) listed and remains Europe's largest listed structure. The building alone covers an area of 17 acres and currently contains around 1,000 flats. In total the whole site covers 32 acres (ref 2). In the new proposal, a part of Park Hill flats will be converted into student housing (ref 5).

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.

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).

Bundek Park is one of the urban planning projects aimed to create a recreational and sports area for the citizens and tourists to support a healthy lifestyle (Ref 3). The lake is surrounded by Bundek Park which stretches for 2,000 meters in length with an area of 35 hectares. The lake is about 5 hectares. the lake was initially used for fishing, walking and swimming. With the increased and carefree use of the lake, the lake and the environment became a waste disposal site. In 2005, by the decision of the Mayor, Mr. Milan Bandić, the renovation of Bundek began. The project included cleaning of the informal waste disposal site and shrubs blocking access to the lakes, renovation of the access to the lakes, planting flowers and introduction of the benches and water also to allow citizens to use the lake for recreation and enjoy the nature (Ref 2).
