The initiative is comprised of a project to recover the coastal line of Alicante, from El Campello to Elx (approx. 21 km long). The Municipality called an ideas' competition with the aim of developing a sustainable coastal corridor project that includes an intervention on the entire Alicante coastline and generates a continuous itinerary integrated into the landscape with new places of opportunity for the residents of the city (Ref. 7). The two-stage competition sought proposals for a new ‘coastal passage’ featuring the creation of new multi-purpose public spaces promoting biodiversity and accessibility (Ref 13). The winner was announced on the beginning of 2019 and the Municipality planned to start the development of the first 2 parts of the project. The winning project of the competition bears the slogan "My connected archipelago" and is the work of the Grupo Aranea and Subarquitectura studios from Alicante (Ref 14), a project that considers ecological and sustainable principles (Ref. 9).

Bastion Theresia Timisoara was built as a defensive perimeter for the Romanian town of Timisoara and has languished for decades in the center of the city. The bastion was rehabilitated and it incorporates green spaces and a community center. The old fortress' location in the middle of town makes it a natural hub for transportation and assembly, and the extensive green roof incorporates it into the city's urban green belt. (1)

Oslo is completely surrounded by old forests full of wildlife and native species, providing important ecological services. This “Green Belt Boundary”, known as Marka, has been approved to be protected by the City Government in order to “ensure that the forests are protected against urban development. The management of the city’s forests follows a multi-user plan based on ecological principles and places the emphasis on a long-term and target-oriented development of a varied recreational forest that allows for nature conservation and outdoor activities”. 1,700km2 are protected by the Marka Act, of where 310km2 are located within Oslo municipality. (Ref. 1,9)

Recognizing that wilderness areas in cities are getting scarcer and neglected, the Biological Station Bonn Rhein-Erft conducted a city-wide project, in cooperation with the municipality of Bonn, funded by the Regional Rhineland Association, whose goal was to assess, map, evaluate and redevelop wilderness patches in Bonn. These contain roadside meadows, flower strips, hedges and small green patches growing on concrete walls or fences and pavement cracks. 10 of these "Wild corners" were designated as micro-wilderness areas, information signs were installed and an informative city walk conceptualized (1,4,10).

"After decades of abandonment and deterioration, Zaragoza took advantage of the opportunity of the Expo 2008, to form a new relationship with the Ebro River, transforming empty, inaccessible, degraded and unsafe banks into places of encounter and representation. Public works on the Ebro were designed as structures with various functions." (Ref.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).

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).

"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".
