Earmarked public budget

The development of the sustainable district of the Haute Deûle River Banks, associated to Euratechnologies TIC center, leans on recognition of water as an element of its foundation. The current innovation is about the water garden. It is a part of the bigger project, building an eco-district on the banks of the Haute Deule river. The water garden, which plays the role of storage (stormwater) and of phytoremediator, evolves with the rhythm of rain and becomes the emblematic place for this work with water. Its vegetation improves every year and the natural seeds of young willow trees contribute to the establishment of a dynamic ecosystem (Ref 1).

The river Emscher is the symbol of one of the internationally most renowned industrial regions: the Ruhr area with its 5 million inhabitants and an important location of key industries such as steel, chemical, and materials industry. The revitalisation of the Emscher over the last 20 years marks a new phase in the region‘s history and is an impressive example of ecological and socio-economic transformation affecting all aspects of life along the river (Ref. 1).

The garden is located on the territory of the social welfare home 'Helclów' in Kraków under the protection of a regional monument conservator. It is supposed to integrate the residents of various age and support physical rehabilitation and leisure with elements of garden therapy. Its main goal is to integrate the elderly from the social welfare home with other citizens through joint activities, such as flowers and herbs planting and caretaking. The initiative involves planting greenery (including 314 trees and 134 square meters of shrubs between 2010 and 2016), setting a grill area, and renovating the infrastructure for the disabled. The garden is supposed to serve as an offset for harmful developments in other parts of the city. Private investors are often obliged to provide resources for new trees in the garden’s natural wall and a noise and pollution barrier. The park is publicly accessible between 9 AM and 6 PM and is available for the organization of events and meetings. The concept to open the previously closed garden to the public was initiated an application for a participatory budget in 2016 and very much supported by all parties involved [1,2,3].

This project was created on the occasion of Lille being the European Culture Capital in 2004. The Park of the Deule was designed to connect the city of Lille with the old mining industry areas along the Deule River. The graphic inscription is a landscape guided by the necessities of topography and control of water (Ref 1). Mosaïc has an area of 33 ha gardens with a pond, woods, and landscapes. Each garden mixes botanical, art and rare domestic animals (Ref 2). The park got the National Landscape Award in 2006 (Ref 4).

In 2013, local activists came up with an initiative to plant 100 trees and 100 bushes in different parts of the District XIII in Kraków. It was supposed to be financed by the participatory budget of Kraków. Still, the delay in implementation led to a situation when the second project by the same team (plant 101 trees and 101 bushes) overlapped with the previous one the following year. The city implemented the original idea, and the district received 100 trees and 101 bushes in 2015. The project aimed to increase the aesthetic and decorative value of the area and to increase the comfort of living of its inhabitants, as well to obtain funds for urban greenery management [1,3].

Together with the Office for Urban Greenery and Waters of the City of Leipzig, the charitable association Ökolöwe Leipzig started the green facades initiative "Kletterfix - Green Walls for Leipzig" in 2015. The project aims at creating awareness about the multiple benefits of urban green walls and inspiring action of tenants and landlords on private property. As a measure mandated by the Urban Clean Air Plan, green facades improve the urban microclimate, general living conditions and combat particulate matter pollution. On-site advice about suitable plants and maintenance is provided upon application and respective seeds for up to 5 plants are sent for free to the applicants by the city department (1, 3, 7).

EPAEM (Euromediterranean public development establishment) launched the development a new park of 14 hectares. Located in former industrial area at the gates of the northern districts of Marseille, it is considered to be one of the poorest districts in France (Ref. 1). The planned park Aygalades is divided into two parts: the southern part of 4 hectares called Bougainville Park and the northern part of 10 hectares which runs along the Aygalades river (Ref. 1). Development work on Bougainville Park is set to begin in September 2020 with completion in 2023 (Ref. 12). The park is described as "the first step of a large project to restore a highly degraded industrial site" (Ref. 12).

The park was completely renovated by planting trees, shrubs, flowers, and by renovating existing grey elements and adding new ones. The project was implemented as part of the programme for Improvement of the Ecological and Recreational environment of Plovdiv, which was funded by the ERDF through the national Operational Programme “Regional Development” 2007-2013 (Ref. 1; Ref. 2; Ref. 3; Ref. 6).

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).

The city of Palermo has planned a series of interventions to regenerate the coastal area in the Southern part of the city (Bandita, Romagnolo and Acqua dei Corsari). The activities performed to reach this goal were the cleaning of the green areas which surround the coast and creation of playground zones for kids. In particular, the green areas were expanded with the plantation of typical plants of the Mediterranean area. This project was aiming to improve the condition of both water and the coast itself, to make it more attractive and accessible to everyone. (Ref.1.)
