Earmarked public budget

The Porous Alley consists of a strip of porous asphalt in a public alley aimed at filtering stormwater and managing runoff in the affluent South End neighbourhood of Boston. Most of the neighbourhood around the NBS location is filled with land that once was tidal marshes, supported by wood pilings, and threatened by falling groundwater levels. The Porous Alley was designed and implemented as a demonstration project to test the feasibility of using porous asphalt to increase groundwater recharge and reduce flooding and water pollution. The increasing groundwater level has high importance in the area the NBS is located in as building foundations are at risk from low water levels. (1,2)

"In Winnipeg, there are several downtown neighbourhood groups (such as the Spence Neighborhood Association, and the West Broadway Community Organization) that make use of vacant urban space for the benefit of indigenous communities, and encourage them to maintain green spaces, ‘tot lots’, and a network of dozens of community gardens. There are also community-led indigenous ‘healing lodges’, Indigenous gardens, medicine gardens, as well as a land-based education programs (e.g. Marymound) using gardening to help at-risk indigenous youth heal from trauma and build resilience in these neighbourhoods." (1 p41).
One such community gardens are the Chief Grizzly Bear’s Garden (in its official, Anishinaabe name: Ogimaa Gichi Makwa Gitigaan) focusing on increasing the visibility of the indigenous community in the Spence Neighbourhood and providing public space for gathering and traditional indigenous ceremonies honoring their connection to nature. The garden is also the place for cultivating native plants significant for traditional medicine practices (1).

Another NBS initiative supporting the indigenous community in Winnipeg will be the Clan Mothers Healing Village and Knowledge Centre (CMVH) initiated by The Elders of Winnipeg. The CMVH will be located in rural Manitoba and provide a land-based, nurturing community living environment for indigenous women and youth who have been victims of intergenerational trauma, sexual/domestic violence, or human trafficking and support their reintegration into society.

In 2014 a counselling office of the NGO Green City was established, entitled The Greening Office (Begrünungsbüro), with the objective of better engaging citizens in green adaptation measures, such as green roofs, green façades, green walls or green courtyards (Reference 1, 5). Financed by the City’s Department of Health and Environment, the project addresses climate change adaptation through greening private properties, achieved through counselling citizens and companies, with diverse outreach and networking activities. The NBS recognised the potential of the many unused private spaces, such as south-facing facades and flat roofs to better adapt to climate change across the entire city (Reference 1).

The Porto Biospots Network is a partnership of the Municipality with "Infraestruturas de Portugal", and is a network of urban forest areas (predominantly autochthonous) that aims to allow the reforestation of adjacent transit routes, major highway nodes, and routes of circulation within the city, transforming environmentally poor lands into green areas that provide multiple ecological services. This initiative foresees the reforestation of 14 areas and the planting of 10,000 trees by 2021, having already completed 2 roads, with a total of 1305 native trees planted. The biospot is the materialization of a part of the Municipal Ecological Structure of Porto. [1][4]

The Gorla Maggiore water park, inaugurated in March 2013, is situated within the municipality of Gorla Maggiore, in the Italian region Lombardy, located about 30 kilometers northwest of Milan. The water park is a constructed wetlands (CW) built on the banks of the Olona river that includes (a) a pollutant removal area composed of a grid, a sedimentation tank and four vertical sub-surface flow constructed wetlands; (b) a multipurpose area with a surface flow constructed wetland or pond with multiple roles; and (c) a recreational park with restored riparian trees, green open space, walking and cycling paths.

The Gran Recorrido de Bilbao (GR), known as the Green Ring or Great Route of Bilbao, is a part of Bilbao’s Green Belt, a municipal initiative that encompasses forest and urban parks surrounding the city. The Green Route aims to skirt the City passing through the forest parks of Artxanda, the mountain of Avril, Arnotegi, Pagasarri, and Arraiz. It completes a route of 99.3 kilometers in a closed belt of trails, paths, roads and streets signposted with references to routes, interesting places, and general information. The Green Route is reachable from the center of Bilbao through eleven additional routes that all lead to a central point. [3][4]

The Lama Balice Nature Park is located near a long 'lama', which is a deep karst gorge, located north of the city of Bari. Established in an abandoned site, the nature park protects the area of the riverbed in the periphery of the city, acting as a natural channel for regulating water flow. It also serves as a recreational and cultural hub, while conserving agricultural functions and maintaining biodiversity. An administrative body consisting of the participating local mayors has been set up to manage the protected area. [1][2]

The Roerplein pocket garden was a Neighborhood Green Plan project. The Neighborhood Green Plans were an initiative of Utrecht Municipality to support the bottom-up 'greening' of its neighbourhoods. Citizens could propose a variety of often quite small-scaled plans that enhance the neighbourhood by means of green spaces that promote social cohesion and thereby community identity. At the Roerplein, a public square was transformed into a green square by way of a participatory process, assisted by a social entrepreneur. The project aimed to reduce heat stress, enhance social cohesion and the attractiveness of the neighbourhood, promote biodiversity and support recreation (ref. 1).

The Tree Strategy is a municipal action plan in progress, aiming to address some of the main sustainability challenges described in the Environmental Program of Malmö City. Its main relations to sustainability challenges include improved health and well-being, decrease differences in those among different social groups and increase biodiversity. The Strategy includes a range of possibilities for evaluating its ecological and social success (ref. 1).

Initiated by the City Administration, NGOs and citizen groups, public funds have in recent years been used alongside partnerships with local businesses, landowners and citizen initiatives to invigorate the East Quarter. This initiative was proposed through the redesign, extension and new development of parks, greening and communal use of vacant plots, the establishment of new urban forests, the setting up of new communal gardens, and the planning and partial implementation of a green corridor for cyclists and pedestrians.
Within this large project, three NBS areas actively contributed to the improvement of the Quarter: Querbeet, Bunte Gärten and Parkbogen Ost (1).
Querbeet is a community garden in the Eastern district of Leipzig, formed in 2012. The garden is lead by democratic self-governance principles where the focus is on shared space, with a focus on enhancing cultural interactions and encouraging active citizenship (1). Since 2017, the plot of the garden has reduced, however, the non-profit organisation formed two new gardens: a community garden and a school garden where environmental education the main activity (2)
Bunten Garten (Colorful Garden) is a community garden and registered refugee aid association that aims to bring residents and refugees together (3) The garden was revived in 2015, and since offers opportunities for recreation, wellbeing and informal support to refugee families (1).
Parkbogen Ost is a scheme focusing on developing unused railway tracks as an arch-shaped, green mobility corridor running along the perimeters of much of Leipzig’s East Quarter and connecting the quarter’s green spaces and providing easier access, by foot or bike, to the city centre as well as to surrounding areas.
