Green space creation and/or management

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 private initiative located in a residential complex in the northern area of Rome. When a new tenant purchases or rents a house, he is provided with a private garden for horticulture, together with the assistance of experts in vegetable planting and growing. The initiative was designed to educate people on the importance of consuming local foods and living in close interactions with green areas inside urban areas (1 and 6).

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).

To promote bee-keeping, the city created the Bee Trail - a circuit where visitors can discover Ljubljana's beekeeping heritage and the significance of bees for our survival. The Bee Trail was designed and opened in 2015 as one of the activities within the Green Capital of Europe 2016 project. It was originally conceived only as an actual route between individual locations related to beekeeping and bees in Ljubljana. Through the participatory principle of working with individual members, however, it has been shown that the path is much more than just a work program or project. It has become synonymous with all activities related to bees and beekeeping in Ljubljana. Since 2011, the Slovenian Beekeepers' Association has awarded municipalities the title of the most bee-friendly municipality. The City of Ljubljana has been awarded the most bee-friendly municipality - in 2017 and 2019. (1)

The largest rain gardens in Sweden (thus far) has been created in Göteborg (Kviberg park). Kviberg's multisport arena was completed in the summer of 2015 in the northeastern part of Göteborg. Around the facility, there are parking spaces with a capacity for 500 cars. In order to handle the rainwater flowing from the parking area, approximately five per cent of the total area has been used for rain gardens, which both clean and store the rainwater. (Ref. 1, 2)

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. (Ref. 1-5)

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).
