Miravete Garden
Huerto del Miravete is one of the several school gardens that have been supported by municipal, regional and national policies for environmental education on orchards. Huerto del Miravete was a two-year-long project, for the creation of a school garden and irrigation system for use by students in the elementary school system. (Ref 1)The presented intervention is an effort to introduce students to the traditional orchards of the region and the labours involved with them, and to educate on ecological processes through student participation in the garden.
Newly created park Vozrazhdane
The first new park in Sofia since 30 years was created, which had very positive reviews from the citizens of the capital. The park features attractive grey infrastructure, grass lawns, and more than 600 planted trees. It has become a popular place for recreation. The aims of the project were to improve the public environment so that it is more suitable for rest; create conditions for sport and recreation in an urban park environment; and to thereby improve the economical state of the region by attracting investments and new employment opportunities. (Ref. 1; Ref. 2; Ref. 3). Extension of a 6.6 acre water park and additional 18.2 acre green area was also completed in 2020 (Ref 8 and 9).
Vegetable and plant production on industrial wastelands
The acronym VERDIR stands for Sustainable Rehabilitation and Responsible Innovation (Valorisation de l’Environnement par la Réhabilitation Durable et l’Innovation Responsable) and is a project of the University of Liège, about the development of local economic activities based on urban and peri-urban agriculture. It aims to convert existing brownfield sites according to the needs of the population. This involves the large-scale production of vegetables and plants which can be used for food but also for the pharmaceutical industry and the production of biomass, which is increasingly needed (Ref. 1).
Wirral Waters project
Wirral Waters is the largest regeneration project in the UK. It will transform over 500 acres of the Birkenhead docklands into an internationally recognizable destination (where e.g. innovation and sustainability will thrive). (Ref. 1, 2). While the whole project will take up to 30 years to finish, the first phase has started in 2019 and building work has begun on three projects which will bring 1,000 homes and breathe new life into 500 acres of former dockland in the town. £220 million will be invested in the next three to four years alone in an effort to build high quality, high-density accommodation with lots of green space and employment opportunities close by (Ref 10,11).
Agrarian Park of Baix Llobregat
The Parc Agrari del Baix Llobregat is located in the floodplains of the delta and lower valley of the river Llobregat, in the Catalan county of Baix Llobregat, in a central position within the metropolitan area of Barcelona. The territory of the park (nearly 3500 hectares), includes a rich traditional agricultural activity and comprises fourteen municipalities totaling about 818,000 residents. It is protected by a specific planning instrument and managed by the Barcelona Provincial Council (Diputació de Barcelona) (Ref. 1 and 9). The park acts as a green lung for the metropolitan area of Barcelona and at the same time as a pantry for Mercabarna, the large wholesale market that provides food and drink to the inhabitants of Barcelona and surrounding towns, although there is also production that is exported (Ref. 10). The Agrarian Park is the only one in the world so close to a large city and it promotes specific programs to preserve the productive values of the agricultural space and promotes quality local products and local consumption. (Ref. 10)
Emscher Landscape Park programme
Emscher Landschaftspark is a regional park system in the northern Ruhr area. It is a regional cooperation project between several post-industrial cities that want to create a coherent park system and regenerate natural environment in the area (Ref. 1). A crucial vision for the redevelopment is that the Emscher Landscape Park would act as a "green connector" between the settlements of the Rhur valley, following the path of the Emscher River and using the abandoned industrial areas along it as a unique form of green space (Ref. 6). "Created after the disappearance and decline of the industry in the area, it has been a key instrument for the territorial, social and economical transformation of what was once the largest industrial region in Europe" (Ref. 12).
Zollverein Coal Mine Industrial Complex
Zollverein is an abandoned colliery and coking plant near the center of Essen in Germany (Ref. 6). Since 1993 the mining here stopped, and the site was turned into a derelict area, so nature could win back its territory. Most of the railway tracks and the smaller industrial leftovers are now covered with moss, grass, and weeds (Ref. 4). After the site was recognized as a World Heritage Site in 2001, it started being developed as a multifunctional cultural, tourist and recreational center keeping and developing biotopes that emerged over time (Ref. 11).
Forest Trail for Educational Purposes
An educational forest trail was developed by the centre for environmental education organization Lipka as part of the ACT WELLL project partnership between Austria and the Czech Republic (2007-2013). (Ref. 2; Ref. 3). The trail includes eight stops on a two-kilometer circuit, where children and adults can learn about how nature works through games and challenges. (Ref. 2). These elements were created by artists Blanka Ponížilová and Hana Havlíčková (Ref. 1). Three-hour field-trip educational programs are available to kindergarten-aged students, and the trail is also open to the general public (Ref. 9).
Sedum roof for Nottingham Trent University
The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).
5 new stormwater retention basins
In 2014, the Marseille Provence Métropole Urban Community commissioned five new stormwater retention basins in order to preserve the quality of coastal waters and reduce the risk of flooding (Ref. 4). In the past, in the event of severe thunderstorms the sewage networks became saturated and a portion of the water was then directly discharged into the sea without going through the sewage treatment plants (Ref. 1). This is seen as "one of the most important documents of recent years in terms of environmental protection. It foresees in the next 5 years, 185 million euros of major works" (Ref. 1).
