Joint implementation (e.g. tree planting)

The city department for green space, environment and sustainability and the foundation citizens for Münster initiated a citizen-based intervention which aims at turning the park area at the "Spickmannplatz“ called "Grünschleife“ into a meeting point for residents and neighbours. The concept for its regeneration is based on workshops and ideation processes of citizens whose involvement goes beyond urban gardening activities but involves an active co-creation of the area by co-planning and development. Apart from several communal restorations works, vegetables, fruits and herbs plantations, a pavilion, a dog station and chessboards with benches were set up (ref. 1).

Warwickshire Wildlife Trust has completed an urban river restoration on the Guphill Brook that aims to restore the brook's natural features and enhance the surrounding habitat. "The project [is expected to] bring multiple benefits to diminishing wildlife and deprived local communities but also importantly to flood risk reduction, which is becoming ever more important with the increased negative effects of climate change." (Ref. 1)

The hurricane Kyrill devastated up to one-third of the tree stock in the city of Münster and thereby changed the green cityscape in 2007. Therefore, the civic society movement "Foundation Citizens for Münster" initiated the project "Bürgerbäume" (literal translation: citizen trees) to foster reforestation of the promenade of the city castle and other affected spots in 2008. In collaboration with the city department for urban green, motivated citizens and citizen groups took over tree sponsorships with up to € 1,000 per tree to help restore the urban green within three months after the event (ref. 1, 4).

Champratel Eco-District is mainly a housing development plan with new green space areas which will be part of the green corridor of the city. "It will be a real "Garden-District" to offer participatory housing: "For La Grande Plaine, the city of Clermont-Ferrand wanted to go beyond the simple redevelopment of a neighborhood by implementing an innovative approach: participatory housing. It's a new way of collectively designing, creating and managing individual homes" (Ref. 11). It will offer harmonious urban forms and vast green spaces. It will mainly offer a concordance between two desires: the proximity of the city and a pleasant living environment" (Ref. 2). Three main green spaces have been created including a meadow in the north, a green square Rose-Parks to create a meeting place for the inhabitants, and diverse gardens (some of which are maintained and others which are wild" (Ref. 5).

In 2011 the Municipality of Lisbon promoted a project for urban gardens in the Horticultural Park of Telheiras (Ref.4).
The park is an allotment garden with the objective of supporting the urban agricultural practice for its own consumption. The residents of the locality had the possibility of renting at a symbolic price, one of the plots made available by the municipality (ref.5).
Beyond the provision of plots, the Council also provides fences, shelters for storage, water irrigation, training and technical support (ref. 1).

Revival is a partnership which is committed to delivering improvements for wildlife and people on the Lower Don catchment from the Don Gorge to Goole. It enables organisations over a whole host of different sectors to come together and work under one shared vision: create a committed partnership delivering improvements for wildlife and people on the Lower Don catchment. This intervention is thus a change in the governance of natural areas in and around Doncaster that leads to projects, rather than being a specific project itself. The River Don Revival project will continue to fight for the river’s future. Firstly, an action plan will layout the manual work necessary to improve the river and the catchment as a whole. In addition, the partnership intends to work with a scheme called the NW Water Rangers to encourage the public to engage in citizen science, collecting evidence of poor water quality. The partnership will also work closely with the South Follingsby Park development to implements Sustainable Urban Drainage Systems, to create new habitats and to improve the river itself. Finally, the partnership hopes to appoint a dedicated member of staff to oversee all of the work taking place on the Don. (Ref 1, 2, 7).

The city of Clermont-Ferrand has 2 sites of family gardens, located at rue Robert Lemoy and rue du Château des Vergnes at which they have installed on a total area of 40 216 m², 172 parcels leased to, mainly, Clermontois residents in apartments without gardens. The gardens are a true place of life for gardeners where families and friends may meet and share convivial moments. Inscribed in a practice respectful of the environment, the gardeners and their cultivations turn toward a kind of agriculture that expects from each gardener an eco-responsible behavior in the production of food (Ref. 1).

The Kersentuin (Cherry Garden), an environmentally, socially and economically friendly community in Leidsche Rijn, an urbanization-from-scratch area in the west part of Utrecht, has been founded and developed by the residents themselves. The area is very popular and is seen as an interesting best practice in ideal green neighbourhood developments (ref. 4). It is a sustainable neighbourhood which integrates technical and social sustainability by building sustainable houses and creating public green spaces that promote biodiversity and social cohesion. The main characteristic of the Cherry Garden is the self-management of the green spaces which is achieved by gardening days. The project was innovative at the time of implementation and inspired many other projects (ref. 1).

The project focuses on the development of a sustainable, social and ecological park that promotes citizen participation (ref. 2), which is one of the largest city parks in the Netherlands. It combines various blue-green infrastructure elements (ref. 1). The park includes recreational facilities, a butterfly garden and special constructions that provide habitat for species. The Máximapark runs largely on volunteers and the citizen participation is the outstanding character of the development of the park (ref. 2).

La Tiretaine is a river in Clermont-Ferrand which, in the past, was harnessed to run underground in order to address hygiene concerns and create more land for construction and industrial purposes (Ref. 5). Rehabilitation efforts have been made throughout the city in order to 'renature' the river. Efforts include the creation of a small park along the river near the school Saint-Alyre in 2008 (Ref. 1) as well as a vision to develop a park surrounding a section of the river by 2026 (Ref. 4).
