The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).

The “Cities Dare Wilderness” project is part of the overall Hanoverian program of “More Nature in the City”, a new future-oriented approach to green spaces in urban areas. The aim of the project is to bring wilderness back to the city by increasing urban biodiversity, strengthening nature in the city and making it habitable for its inhabitants. For fulfilling these goals, eleven sites were chosen (some parts of the city park Eilenriede, some currently intensively cultivated areas or some derelict small gardens), in which different methods have been tried out, like planting local woody plants, grazing, and the implementation of interpretive trails. The development of the flora and fauna in the new wilderness is now being observed and investigated. The first step in the wilderness was made on a meadow along the course of the Fße in the Badenstedt which was fenced. It was made available for cattle to graze and influence the new growth of shrubs through feeding preferences (Reference 1, 2). The flowering meadows have attracted a variety of species. The rich habitat resulting from the project has attracted songbirds, hedgehogs, butterflies and some of the 67 bee varieties endemic to the state of Saxony (Reference 10).
Campaigns for environmental education are regularly offered in order to involve the population in the process of wilderness development. The series of “Wilderness Concerts” were organized, a “wilderness woodlice” was installed in one of the project areas (Mittlefield), and handicraft activities have been regularly offered, in addition to excursions and guided tours (Reference 8). Citizen science is also part of the project through the iNaturalist app that allows the community to record observations of the flora and fauna in the area (Reference 9).
The project is financed by the Federal Ministry for the Environment, Natura Conservation and Nuclear Society. Two other cities, Frankfurt am Main and Dessau-Roßlau is also involved as model cities. (Reference 1,2)

In 2014, the Marseille Provence Métropole Urban Community commissioned five new stormwater retention basins in order to preserve the quality of coastal waters and reduce the risk of flooding (Ref. 4). In the past, in the event of severe thunderstorms the sewage networks became saturated and a portion of the water was then directly discharged into the sea without going through the sewage treatment plants (Ref. 1). This is seen as "one of the most important documents of recent years in terms of environmental protection. It foresees in the next 5 years, 185 million euros of major works" (Ref. 1).

When the national German railway company shut down parts of the former East station of Leipzig and its tracks in 2012, citizens developed an idea for its secondary use and came up with the concept of the "Parkbogen Ost" which represents a 5-kilometre long circle of bicycle lanes, footpaths and outdoor space surrounding the East of Leipzig. The city of Leipzig recognized its potential to connect the Eastern Leipzig with the city centre and developed the strategy further by issuing a "Masterplan Parkbogen Ost" as the base for a step-wise implementation of the project in 2013 (Ref. 5).

In 2017, the Sintra City Council opened a new urban park in the quarter of Cavaleira, with 25 thousand square meters that are inserted in urbanization where about 5 thousand people live. The park has zones of stay and of leisure, circuits of exercise for adults and seniors, children's green playground, pedestrian routes, canine park and the entire park has a green turf cover.
The design of the park, an investment of around 600 thousand euros, counted on the active participation of the population through ideas for the final project. (ref.2)

The scheme was designed to manage surface water runoff from a 1 in 30 year event and to always intercept and treat the, often more polluted, first flush of highway runoff (ref. 1). A total of 21 linear rain gardens (total of 148m2) were constructed within the grass verge, allowing for the constraints of access, below-ground services, street furniture and trees. The rain gardens utilise a combination of clean stone aggregate and proprietary units to create void space beneath a planted topsoil layer. They were designed to capture runoff from 5500 m2 of highway from a total surface area of 7100 m2 (ref. 1).

“Nottinghamshire Wildlife Trust (NWT) in partnership with Nottingham City Council (NCC) proposed enhancements to the Fairham Brook nature reserve to allow areas to be re-wetted, restoring areas to their former state. The Fairham Brook watercourse within the reserve was deepened in the 1970s to improve its drainage function for the adjoining agricultural land but it had the effect of draining the reserve also, which is one of the few areas of fen habitat remaining in Nottinghamshire. Fen is a Nottinghamshire Biodiversity Action Plan priority habitat and all efforts were to be made to protect and restore the areas that are remaining. Lowland Fen was also a UK Biodiversity Action Plan priority habitat (ref. 1).

JDS Architects Designed a Geometric Green-Roofed Youth Center for Lille, France. Organized around a massive courtyard, the three sections of the triangle building each feature a roof that serves as an integral part of its sustainability. The kindergarten roof was planned to be a vegetated garden area with a grassy play surface that helps cool the building. (Ref 1)

Located in the backyard of a memorial house, this NBS was created with 2 purposes in mind: to offer a green oasis to the inhabitants of Iasi but also to educate them since the garden itself relies on volunteers primarily who have the opportunity to come and work in the garden, assist in the process of growing food and learn how to lead a healthy life. In a way, this garden is seen as an escape from city life and it combines education with practical skills and community cohesion (1)

The Ronald McDonald House is a temporary home for families with seriously ill children who are treated at the Essen University Hospital. The house was designed by the artist Friedensreich Hundertwasser, who merged the garden and architecture together in order to bring residents of the house closer to nature improving their psychological and health conditions (Ref. 1). The house was opened in 2005 in Essen's Grugapark (Ref. 2). A special highlight is the accessible intensive Green Roof (950 sqm) with grass, herbs, flowers, shrubs, and trees (Ref. 3).
