Environmental quality

Each year, since 2003 between 22 March, World Water Day, and 22 April, World Earth Day, the traditional spring cleaning campaign For a More Beautiful Ljubljana (Za lepšo Ljubljano) is in progress in Ljubljana. The basic goal of the For a More Beautiful Ljubljana campaign is to give a thorough spring clean to functional areas across the City of Ljubljana, and those taking part include Departments within the City Administration, the City’s District Authorities, public companies united within Ljubljana Public Holdings, City of Ljubljana public institutes and various Ljubljana societies.

Opened in 1987, Lo Morant Park is located in the northern part of the city of Alicante. Its flat surface of 12 hectares is ideal for walking among its vegetated spaces and for the development of multiple activities focused on the neighborhood (Ref. 1). An educational environmental tour of the park is in place for learning and discovering the fauna and flora. The park offers different social activities and facilities (sports facilities, leisure). (Ref. 1). It is the largest park in Alicante with a dimension of twelve hectares, and has a great diversity of plant species and sports and cultural spaces. (Ref. 3)

The Urban Ecology Agency of Oslo (Bymiljøetaten) installed two CityTrees in the city of Oslo to act as green lungs in the city and reduce air pollution. The two CityTrees were placed at the Solli plass by Sommerrogata and on Nordraaks plass, close to Slottsparken. The CityTree is an environmentally-friendly plant wall with benches. (Ref. 2) It is an invention of a German company, Green City Solutions, and acts both as an aesthetically attractive furniture for resting, while simultaneously combating air pollution in city centres.

The Park Jose Antonio Labordeta is the most extensive park in all of Zaragoza, consisting of municipal nurseries, botanical gardens, and areas for leisure and recreation. (Ref. 4) From 2006 to 2007 a process of citizen participation was started to collect ideas for the improvement of the park on its 75th anniversary. (Ref. 1) In 2010, the City Council of Zaragoza developed a Master Plan to document these ideas and to guide future management of the park. (Ref. 1) The interventions in the Master Plan include landscape improvement, park management, agronomic improvements, among others. (Ref. 1)

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. (Ref. 1, 3, 4)

The aim of Ljubljanica Connects funded by Life+ is to improve connectivity between Natura 2000 sites. Started in 2012, the project aims to remove barriers to fish migration, enhance and restore habitats, improve water management infrastructures, and put in place a water monitoring system. This will restore the river Ljubljanica's function as a corridor, improve water management and so provide better links between Natura 2000 sites. The fish species in question are Danube Roach, Danube Salmon and Striped Chub (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).

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).
