Achieved impacts

The municipality aimed to establish a zone in Murcia that worked as a "green lung" for the city while making it its engine for economic, social and cultural development (Ref 2). For this, the municipality planned and implemented the project of "Integrated Alcantarilla Parks". It includes several parks, with the priority of creating one in the surroundings of the Ethnological Orchards Murcia's Museum (Ref 1). The project is called integrated as it is based on the integral values of sustainability where the environment, the economic development and the socio-cultural needs are compatible (Ref 2). For this, there will be sustainable architecture, recovery of the natural environment, as well as incorporating the historical heritage in the public green areas of a specific zone (Ref 3). There are many parks that are part of this project, the last one was the Ibarra de Murcia Park in 2020 (Ref 7 and 8).

A green roof of the total area of 362 m2 was established in a modernized historic neighbourhood in the centre of Bydgoszcz. The rooftop serves aesthetic and recreational purposes for the residents and visitors. Selected plants retain as much as 40-99% of rainwater and absorb air pollution [1].

On the brownfield of an abandoned train station and its surrounding terrain, active citizens and neighbors developed Utopia town, a living lab for creative urban development, cultural and creative industries, and citizen engagement. Under the guiding principle “edible train station – edible town", next to other projects, an urban garden with organic cultivation was developed on 1,000 sqm of the terrain at the former train station Mirke as a focus area for their activities due to its favourable location in order to show that gardening is possible in urban spaces, even on balconies or terraces (Ref. 1, 2, and 3). The main building of the Utopiatown has a bar, a concert venue, a food sharing station, and a free bicycle lending service that is operated by volunteers. (Ref. 9). Gardening workshops that are offered to citizens with little experience of gardening are planned to be further extended with seminars and practice classes for students (Ref. 3). Since its beginning, the area of the “utopia town” has grown rapidly and is now providing opportunities for multidisciplinary academic research. (Ref. 12)

Students and teachers of the Faculty of Biology at St. Kliment Ohridski University created a habitat for birds, invertebrate species, and plants. The project aimed to popularise easy steps for increasing biodiversity in urban green spaces and effective practices for preserving it. The created habitat also aims to develop and solidify the biological and conservation knowledge of pupils, university students, and the citizens of Sofia, and to help restore the vanishing bondage between contemporary society and nature. Activities have included planting grasses and shrubs by volunteers, placing bird houses, and educational events. (Ref. 1). For the purposes of "Starling on the doorstep" volunteers among students and teachers of the Faculty of Biology began to develop some of the green spaces in front of the building by enriching the surrounding vegetation, and with it the diversity of animals. It was important for them that the transformation took place right in the yard of the faculty, where the future biologists are trained - the people called to take competent care of nature conservation. The idea for the initiative was warmly accepted by both the dean's management of the faculty and the ecology expert from the Municipality of Lozenets, on whose territory the school is located. (Ref 3)

The area of the Port of Antwerp is one of the most important habitats for threatened species, even at the European level (Ref. 1). Therefore, a species protection programme was launched in 2014 for the conservation of 90 protected species by means of creating an ecological infrastructure of green areas, green corridors and small green spaces that include spawning grounds, ecological river banks, and road verges (Ref. 1, 2, 3).

The project has the goal to promote volunteering related to environmental protection. The community-based initiative involves disabled people to implement the intervention - with the supervision of specific tutors - to prove that they can be an active part of the population. Activities included taking care of several green areas and implementation of social horticulture gardens. (Ref.1.)

In 2011, the Great Lines Heritage Park was formed by connecting the Great Lines, Lower Lines, Inner Lines, Forst Amherst and Medway Park together. To do so, a former military area was transformed. The intervention connects the heritage towns of Chatham and Gillingham and the Chatham Waterfront. By connecting the heritage of the town and the waterfront, the project aimed to emphasize both these aspects of the area, but also to improve visitors' access and be a habitat for a number of species (Ref 2). The area has been created from a site that is of international heritage significance. The park is located within the Thames Gateway priority housing area, Europe’s largest regeneration project (ref. 3).

Following the Reading Growallot scheme, a derelict land area in Florian Gardens, Southcote was transformed into an allotment site. The scheme is part of Food 4 Families which is a community allotment project. One in four residents in Southcote live in flats with no garden to enjoy; local families have therefore transformed the land into a thriving allotment, growing fresh, healthy fruit and vegetables. This means that Southcote GrowAllot gives residents the chance to start growing food together. (Ref. 1, 3)

Following a severe storm in 2000 that overwhelmed the sewage system of Portsmouth along with its main Wastewater Pump Station, causing major flooding in the city with the destruction of private and public properties, prevention of such events become a key priority (5).
The Portsmouth Flood Alleviation Scheme aims to relieve the pressure on the sewage system in wet weathers by diverting the accumulated surface water flows away from the combined sewer networks and discharge them into the harbours around the island (5). The Scheme consists of several measures across the city, among others the creation of a new open watercourse channel across the Great Salterns Golf Course diverting surface water directly into Great Salterns Lake (5). This measure of the scheme is a solution that separates surface water to provide resilience, boost flood protection and benefit the environment with the minimum of new infrastructure (1).

New recreation zone "Norikus Bay" in Nurenberg was completed in 2018 on the south bank of the Wöhrder lake, an artificial lake created in 1968 to protect the city from flooding. The dam itself, which is a 400m long path separating a part of the water surface from the bigger part of the lake, has become a tourist attraction with a water playground and other recreational amenities being offered. The water is naturally cleaned through the regeneration zone with natural plant filter, and simultaneously improves the habitat of fish and makes recreational swimming in possible in the cleaner water. New green areas are organized on the shore in order to improve environmental, aesthetic and recreational conditions of the area (1, 7, 8).
