Earmarked public budget

The city of Salford has experienced several floods and is at risk of flooding once every 100 years (Ref1). The majority of properties in the city that lie in a high-risk flood zone are in the floodplain of the Irwell. The UK's Environment Agency and the council, designed a flood prevention scheme which included temporary water storage areas which will store floodwater on the existing Castle Irwell playing fields and public open space, and double as sports area otherwise (Ref 5). It aimed to have its own wetland and wildlife habitat, and will help protect hundreds of homes and businesses (Ref 4).

Arcosur is a new residential neighbourhood project approved for construction in 2008 after the hosting of the Zaragoza Expo 2008. In its structure, it seeks to develop a space of 4 500 000 m2 into around 21 000 new homes, and out of which around 1 500 000 m2 will be squares, parks, and other green spaces. These green spaces would connect the neighbourhood and ensure all residents have access to green areas. (Ref. 1)

Coal mining in the Dearne Valley damaged the Dearne Valley landscape. To address these problems the Dearne Valley Green Heart partnership was formed in 2006, but the intervention discussed here is specifically related to the developments between 2012 and 2015, when it was founded as a Nature Improvement Area. It is part of the South Yorkshire Delivery Programme and part of the Doncaster Council as also being part of the Doncaster Green Infrastructure Strategy (Ref 1, 2).

In 2010 a new drainage system was installed in Traktoros Street that solved the disposal of surface-water so that bigger storms would not cause damages in the area and separates rainwater from the sewage. The rainwater is directed to the lake in Adyváros. The project was the third phase of the complex reconstruction of draining in the Szabadhegy neighbourhood. While the first two phases (the construction of the main pipelines and drainage of Pannónia Street; drainage of Vak Bottyán Street and paving streets) were financed by the municipality, the third phase was implemented with the help of the EU. (Reference 1, 2)

As part of the restoration of park Denis Gardens, an innovative water element was built consisting of water flowing down the stairs, circulated and cleaned by a pump and filters. This helps regulate the local microclimate by reducing temperatures in hot days and creating humidity in the air (Ref. 1; Ref. 5). Also, the element allows people to walk bare-footed and cool off. In addition, the water reduces air pollution by extracting dust from the air, and the structure has an aesthetic and recreational function, with a restaurant underneath. (Ref. 1; Ref. 2; Ref. 6).

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).

The initiative promoted by the event “Primavera Mediterranea” (Mediterranean spring) transforms the central pedestrian area of via Argirio into an urban park. The project is aimed at rethinking the urban spaces in a green way, as urban gardens are built within the whole central area. The main benefit of the initiative is to give a green view of the city centre, a new dimension of the lived urban space. In addition, workshops and manifestations are organized within the area, to promote also the social and cultural value of the zone. (Ref.1.) The intervention is an initiative taking place every year since 2011, which lasts for days. Private shops, associations and consultancies work together to realise the urban gardens in the main street in Bari. (Ref.1.2.&3.)

"This 26-hectare park, the largest in Clermont-Ferrand, offers a privileged view of the city. Several wooded areas serve as shelters for permanent and passing wildlife. For the last two years, gardeners in the park have no longer used pesticides to maintain Montjuzet Park, the effects are already measurable on the enrichment of flora and fauna." "During the development of the Parc Montjuzet, the choice was made to keep 9 hectares without intervention. These hectares could be a source of some ecological richness. Hives have been established near this area since 2009." (Ref. 1) This park has the Refuge LPO label. (Ref 2)

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).
