Environmental quality

Revitalization of Rakova Jelša includes cleaning of the informal waste area and renovating it in a park which connects the city with the Marsh Landscape Park. In two phases, the park area was arranged together with the children's playground and the footbridge over Lahov graben. The possibility of regulated urban self-sufficient agriculture or gardens in the immediate vicinity of the city center means the added value of this area. (1)

Göteborg is in need to strengthen the conditions for those who today, to a certain extent, rely on food production or farming. Also, the demand for locally produced and non-toxic food is increasing by Swedish consumers. Green Production aims to create opportunities for urban agriculture that is financially viable within and around the city. Green Production will build knowledge and conduct research by bringing together key stakeholders around a number of focus-projects within the area. Green Production aims to create opportunities for urban agriculture that is financially viable within and around the city. Green Production will build knowledge and conduct research by bringing together key stakeholders around a number of focus-projects within the area. The original idea regarding these focus-projects is that they either will be based in a specific spot and, for example, linking new technologies with new jobs, or involve a process where entrepreneurs meet landowners, consumers, wholesalers, etc. The goal of these focus-projects, in addition, to gather knowledge and create new contacts and networks, is that they may develop a number of innovative urban agriculture projects and business ideas in and around the city.

The recreational and educational centre (RIC) area along the Sava river stretches from Tomačevo to Sneberje and totals 144,618 sqm. The area is intended for children, people with disabilities and other residents of the region, visitors and tourists. The intervention made this once degraded, illegal dumping area attractive for those seeking recreation, visitors and tourists, also in the evening as street lighting was installed along the path powered by photovoltaics. A large children's playground offers free socializing and children can develop their basic motor skills, which is exceptionally important in life's early years. (1)

FutureBuilt is a program running between 2010-2020, with expectations to continue from 2021-2030 (Ref. 9). One of its projects consists of the construction of a large greenhouse in between a housing complex in an old industrial building. The greenhouse will be the centre of the building and provide a Mediterranean climate with a lot of green facades, green roofs and indoor vertical greeneries (Ref. 1). The nave of the complex will become a greenhouse and the natural gathering point for the residents. (Ref. 1, 3)

The Ville Forests covering the hills between Bonn and Cologne are an example of a rare and highly endangered forest habitat type in Europe giving a home for many threatened animal species (1). The protection and conservation of these 'oak-hornbeam forests on hydromorphic soils and the forest-dwelling species was the main objective of the Villewälder: LIFE+ Project for Kottenforst and Ville project which includes four Natura 2000 areas with 4.378 hectares of forest. The conservation measures of the project focused on water balance restoration, habitat improvement and preservation, and the extension and connection of protected areas (1,2).

This underground garage in Alicante, Spain, received a green roof makeover according to Alicante's climatological conditions (Ref. 2). Urbanarbolismo, a Spanish firm with a strong focus on vegetation, designed and installed this succulent garden in the courtyard of the garage. The garden is very low-maintenance and doesn't require any irrigation whatsoever. Further, with every passing year, it will grow more and more beautiful as the plants grow larger and take root. The Urbanarbolismo Benisaudet IVVSA parking garage was created by this Spanish design firm with the purpose of "keep[ing] the underground lot cooler, as well as improv[ing] its air quality." (Ref. 1)

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).

The first " ecological zone" in Ljubljana was established in 2007 in the old city centre. This led to the closure of a 100,000 m² area to motor vehicles, and the renovation of the main traffic axis to make it attractive for pedestrians and cyclists. The new transport regime in this area reduced black carbon levels by 58%. Additionally, the city administration has planted 63 ash trees. Biking and sustainable mobility have been promoted, in line with providing new green areas for social and sporting activities in formerly degraded areas. The "renaissance“ is not focused only on the city center and the implementation of the car-free zone, but it is expanded throughout Ljubljana and covers different fields, such as the revival of degraded areas, the establishment of green public spaces, playgrounds for children, eco-renovation of schools and kindergartens, cultural and sports facilities, etc. Finally, the river Ljubljanica has been the focus of an ecological restoration project. This was done with the aim of reducing pollution and returning the city centre to the citizens, by incentivizing pedestrian and bicycle commute. The "ecological zone" project has been completed. After the completion of the project, further initiatives were taken which is directly related to the project itself. Some of them focusing on converting the city to a sustainable one is still going on. (1, 3, 4 and 8).

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).
