University Park Essen
The ‘University Park Essen’ is developed on a former railway site in the inner city of Essen, that had been a wasteland for almost 30 years. By revitalizing this about the 13-hectare large plot, an urban green quarter for residential and commercial use is created. The centricity of the park within the new quarter between the city center, shopping mall Limbecker Square and the university campus is the first visible component of the development and therefore shapes the new identity of the quarter (Ref. 4).

Vegetable Garden On The Roof Of The Pasteur Clinic
The Pasteur clinic in Toulouse installed a 500m² vegetable garden on the roof of its building in 2014. Maintained by clinic employees and various associations, the garden makes it possible to develop a friendly atmosphere and learn gardening while promoting biodiversity (Ref. 2). The garden grows produce including green beans, tomatoes, basil, strawberries and raspberries, (Ref. 3) and contains flowers such as nasturtiums, Cosmos, tagettes and edible chrysanthemums (Ref. 4).
Niederfeldsee
A new lake with green banks was built in the district of Altenhof in Essen in order to improve the quality of life in the neighborhood, create new recreational facilities and prolong the existing transport and green infrastructural developments in Essen. The water is supplied to the lake by means of groundwater from a separate well, as well as rainwater from the surfaces of neighboring roofs (Ref. 1).
Afforestation of the yard of hospital "St. Panteleymon"
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 Gardens
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)
Villa Turrisi historical park
The Villa Turrisi park has been the subject of a regeneration process request, implemented by some associations and citizens in order to protect the park. The goal of this citizen-based initiative is to regenerate the area with the expansion of the urban park, by adding several trees and plants. The main benefits of the project, apart from the cultural and social value of the new area, is the mitigation effect of the park in response to threats such as urban pollution, improvement of air quality, and biodiversity conservation (both plants and animal species). (Ref.1.)
Forest Protection Curtain in Iasi
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)
Recreational area Ciric
The Ciric Entertainment Area is a bordering area of the city, located 6 km away from the city center. Before the Second World War Ciric did not exist on the map, being a hollow valley without a forest. Nowadays, being arranged as a recreational site, Lake Ciric is surrounded by a beautiful forest. The rehabilitation aimed at creating easy access to the area, to include it in the functional green area of the city and to increase the quality of life for Iasi's inhabitants (1, 2).
