At the primary school Laterna Magica, a green rainproof playground was created that is effective in stormwater retention, reduces soil erosion, supports biodiversity and provides education possibilities for the children. The playground consists of bioswales, terraces, diverse and pollen-rich vegetation and a vegetable garden. (1,2)

The Garden Janine (formerly called Jardin Nouveau) group is participating in the "Aix en Transition" initiative, which wants to increase food and energy resilience in order to better prepare for the future. This group initiated and supported the establishment of a vegetable garden benefiting homeless people, hosted in the Humanitarian Division of the "Jas de Bouffan" district (Ref. 1). A garden was previously cultivated on the area, but had become dilapidated. In 2019, much of the area was repurposed as an orchard as the vegetable garden was deemed to require too much continual presence/labour (Ref. 6).

“The Went Water Vole Project, a two year project working with local people and landowners throughout the River Went catchment to secure the future survival for one of the most significant water vole populations in West Yorkshire. Work also involves carry out habitat restoration and creation schemes across the area to link up isolated water vole colonies and encourage the re-population of some of their old ranges.” (Ref. 1)

The Sunderland Greenspace Audit explained the city's green space in detail and set guidelines and standards that will help to ensure that all areas of the city have a range of quality green spaces available to them. Hereby the Sunderland City Council wished to improve the green public spaces to retain existing residents and attract new ones, to enhance the image of the city and for it to be used as a means to attract future investment in the form of new shops and jobs (Ref 1).

The green initiative 'Oost Indisch Groen' (East Indian Green) is a citizen initiative to make the neighbourhood more sustainable, fun and healthy by means of active citizenship. The key NBS initiative is the neighbourhood garden ('Buurttuin Oost Indisch Groen') in which vegetables are grown with a community kitchen that supports social cohesion and that also gives space for an educational workshop on gardening and sustainability-related topics (1, 6,7)

A long-awaited flood defence scheme which is designed to protect the city from a repeat of the devastating floods in 2007. "The ambitious project has taken 14 years of planning" and will protect the city's gateway (Westgate). The project manager from EA, said: "The work we're doing on the Ings Beck scheme will mean Wakefield is protected against the kind of flood that only has a one in 100 chance of happening in a year." The scheme involves solving the flooding problem and encourage wildlife habitat. (Ref. 1)

The Aa promenade, created in 1950 to provide the citizens of Muenster with a green experience trail in the inner city, was redeveloped in the 90s with several planting measures on riverbanks, walls and in adjacent areas. Next to a brochure, a nature trail which combines the existing recreational with an educational component was created with 18 site-specific signposting points. They cover multiple benefits and ecological functions of urban green spaces, city trees and green facades/walls (microclimate regulation, air quality, CO2 capture), anthropogenic threats, unknown biodiversity hotspots and natural monuments (Ref. 1, 3 and 6).

The Green Ventilation Corridors network in Stuttgart, Germany is an implemented nature-based solution coupled with regulatory policies and incentives. Within this initiative, Green ventilation corridors were created to enable fresh air to sweep down from hills surrounding the city (4).

Bute Park is a riverside green spot with an arboretum and gardens, containing a broad range of ecosystems supporting a wide variety of living species (ref 4). The historic Mill Leat had been dry since the 1970s."The word "leat" refers to "an open watercourse conducting water to a mill". The Mill Leat sits on the same site as a former millpond at the end of the original medieval millstream. It supplied water to corn mills located to the south of the Wst Gate and contained water well into the 1970s." (Ref 10) .Mill Leat Restoration or the re-flooding of the dry water body was a major deliverable under the Bute Park Restoration project (ref 2). In 2013 the overgrown channel was excavated, lined and refilled with water as part of the Bute Park Restoration Project (Ref 2). It enhanced the character of the park and provided a new habitat for wildlife (ref 1). Now re-flooded, Mill Leat is self-contained, self-regulating and self-circulating. It has reduced the risk of flooding and created a sustainable water feature (ref 2).

The Knowledge Mile Park initiative in Amsterdam aims to transform the long, busy and traffic-heavy street in downtown Amsterdam into an environment greener, more sustainable and more livable through the implementation on various Nature-based Solutions (9). Smaller projects include the creation and maintenance of pocket parks, green walls and facades, green roofs and living labs. The idea of the initiative came from the Knowledge Mile Community that aims at making Amsterdam more green, clean and smart by means of innovative solutions regarding air quality, climate change resilience, biodiversity and social cohesion. (1) municipality of Amsterdam and the business investment zone BIZ Knowledge Mile are working together with partners on the realization of the project (9)
The project is still ongoing, although parts of the Knowledge Mile Park are already created in 2016 including one living lab, two green roofs, a green canopy and a pocket park and other parts are planned such as the smart green wall (1)
