Transformation of previously derelict areas

The municipal agency Gardens and Parks collaborated with the hospital "St. Panteleymon" in Plovdiv in order to restore the condition of their rehabilitation park in the yard. This involved planting 550 trees, cleaning and securing the area, and removing or modifying problematic trees. The park has thus become a more hospitable place for rehabilitation of patients (Ref. 1; Ref. 2).

Arkwright Meadows Community (AMC) Garden is situated in the heart of inner city Nottingham, Prior to 2001, the site was a disused, derelict and rubbish-strewn piece of land. In 2001, a group of Meadows residents came together to improve this derelict piece of land and work started to create the infrastructure of the community garden. The area was transformed into a green oasis and outdoor learning environment. (ref. 8)

The ANNALINDE gGmbH operates multifunctional urban agriculture and demonstration projects in the Western part of Leipzig: a community garden, a nursery and a fruit garden on a former train station where the emphasis is on community development and mutual learning processes in addition to food production. This is safeguarded by an events portfolio consisting of garden working days, workshops and collaborations with schools, kindergartens and like-minded organizations. In addition to that, open urban labs are operated for a number of initiatives and projects covering subject areas like urban agriculture, recycling, composting, urban bees, urban resilience and sustainable urban development (1).

This NBS refers to a curtain protection forest that was planted 6 km out of the city of Iasi in 2015 by the mayor of a commune next to the city. The benefits of this NBS embrace also the city of Iasi as a method to prevent flooding and to avoid strong winds in the area. Afforestation was seen also as a response to the existence of arid soil and abandoned crop fields in the area due to a large population movement of immigration towards Western countries (1)

After being abandoned for more than 10 years following the collapse of a building, a piece of land inside the city's "Le Panier" district was approved by the city in 2017 to become a "neighborhood garden" combining green space and a community vegetable garden (Ref. 1). After many delays the project was completed in early 2020 and the garden opened on February 28, 2020 (Ref. 11). The district "Le Panier" (where this intervention occurs) attracts many tourists every year for the charm of its narrow streets and colorful facades (Ref. 1).

A 5km section green corridor in the province of Malaga. The initial intervention was planned and opened in 2015, converting non-operational train tracks into a green path for pedestrian and cyclist use. (ref 1,4). The whole corridor will unite the Natural Site of the Desfiladero de los Gaitanes with the natural site of the mouth of the Guadalhorce river. (ref 3)

The biotope Schladitz is the regenerated remains of a former installation for the dehydration of sewage sludge implemented in 1952 by the communal waterworks company which used to pump its sewage sludge into the municipality of Rackwitz North of Leipzig. Upon its termination (1990), the company conducted large regeneration works of the contaminated sites from 1991 until 2011. The area was renaturalized, a biotope was implemented with plants species to retain the toxic substances. Now the area is also used for nature experience, observation and environmental education for children and adults (4, 7).

Allotment gardens have a long tradition in Hannover, with approximately 20.000 gardens stretching around the city as a green belt. In the last decades, some gardens were threatened by disappearance due to investment interests (Reference 1). With the goal to protect these gardens, the city employed a so-called "Kleingartenkonzept" (allotment concept) in 2016 with the help of the association of allotment gardens (Bezirksverband Hannover der Kleingärtner e.V.). The concept aims to keep the number of existing gardens for social and ecological considerations while allowing for new residential investments which is vital for the growing city. (Reference 2).
As part of the concept, extensive inventory examinations were conducted on areas affected by conversion and restructuring, along with the start of implementation of smaller development projects for housing and the creation of replacement gardens in some areas. Because the need for residential spaces has been covered for until the end of 2019, the conversion of allotments for the said land use has been stopped; it will be revisited in 2024. (Reference 2)
To address the problem of future allotment garden losses, gradual elimination of permanent vacancies has started by creating new smaller and more attractive gardens from oversized ones, by improving accessibility and optimizing spaces, and by modernizing allotments (Reference 2).

The project RUIS (Riqualificazone Urbana Infrastrutture e Sicurezza), stands for the regeneration of urban infrastructure and safety. The initiative is carried out by the municipality of Palermo, in order to improve the urban resiliency of the intervention area, with the creation of further green areas in neighbourhoods dealing with problems of heatwaves and environmental degradation. The main areas which will be the focus of the regeneration process will be those considered to be in degradation state. It is expected that the quality of life of the residents will significantly improve (Ref.1.).

The former site of the Krupp cast steel factory was transformed into a 230 hectares green belt stretching from the city
center to the district of Altendorf, while the adjacent industrial wasteland was turned into an 11 hectares add-on to the Krupp Park (Ref. 1). The landscape vision "Freiraum creates urban space", in which the Krupp Park is a building block, is a comprehensive strategic approach that aims to gradually build up new urban landscape structures and to create diverse qualities of location for different urban uses" (Ref. 9).
