The surface water system in the VINEX location Leidsche Rijn near Utrecht is a special water system. Nowhere in the Netherlands is the surface water of such a large urban area treated in such a sustainable and climate-proof manner (ref. 2). In Leidsche Rijn, a relatively new city district of Utrecht, a sustainable closed circuit water system was introduced including natural wetlands, bioswales, pumping stations and permeable paving which filters stormwater organically. It is viewed as a more sustainable solution compared to traditional stormwater infrastructure because it benefits biodiversity (e.g. by means of fish passages) and prevents the need for storm water facilities and the influx of unfiltered surface water from elsewhere (ref. 1-3).

An ephemeral garden has been set up in Stanislas Square each year since embellishment and pedestrianization works took place in 2005 (Ref. 2). The Parks and Gardens Department of the City of Nancy works around a topical theme, unveiled at the beginning of the summer: such as travel, history, or technology. The city imagines flowerbeds which cover up the square, with flowers and poetry. It is intended to offer visitors a new perspective on the square (Ref. 2). In 2015, the project's theme was "Connected Garden" combining technology and nature (Ref. 3).

The Sun Lane nature reserve in Burley-in-Wharfedale is the second site in Bradford to receive the Local Nature Reserve (LNR) status. The land was used as a garbage dump and reclaimed in the 1970s. (ref1) Pollution from the landfill site was leaching into nearby watercourses and in 1993, Bradford Council undertook a scheme to cap the landfill and restore the site. They installed a reed-bed purification system, to eliminate pollution from contaminated water and add to the reserve’s biodiversity. The Burley Village Wildlife Group began conservation work to enhance biodiversity. (ref4) In 2003 a group of volunteers took over the maintenance of the area and now help to manage it in collaboration with Bradford Council (ref 5). As the site heals at its best, forty-two Common Blue butterflies were recorded together in 2006 (ref 5).

A nature park in Bucharest containing the wetlands surrounding Lake Vacaresti. It was initially a swamp drained by the communist regime, which builds a complex of apartment blocks. In 2014 it was declared protected by the Romanian Government and named Văcărești Nature Park, and was approved as a natural protected area in 2016. (1)

A community garden at the margins of Bucharest, which aims to serve both locals and tourists, and the only place of its kind for the 240.000 inhabitants of the quarter. Apart from its educational aspects, the garden is a living workshop and a place of relaxation for its visitors (1).

The intervention was supposed to be implemented by the project group "Green Facades" consisting of the urban initiative "SchwarmFarm", the research project Quartier Zukunft and citizen volunteers. Greening facades in the Oststadt district of Karlsruhe with hops (climbing plant) to contribute to the cooling of the urban microclimate was their primary goal. Additionally, the harvested hops were envisioned to be used by local breweries for brewing (Ref. 1) Although the project group dedicated to the project was cancelled, there are plans to continue the project in private. (Ref. 2)
The leaders of the project have cancelled it, but it may still be implemented privately in a different form. (Ref. 2)

The intervention at Ness Gardens was a result of the recommendation from the landmark 2010 report - 'Towards a New Social Purpose: Redefining the Role of Botanic Gardens'. (Reference 2). It is part of Growing the Social Role of Botanic Gardens research project, whose aim is to work with local communities on common issues of social and environmental importance (Reference 2). Additionally, as part of the University of Liverpool, the Gardens provide a resource for research programmes (Reference 3).
The project involved workshops, designed to support the botanic gardens through their engagement with their social roles and help them deliver their chosen project. The three participating botanic gardens were asked to develop and deliver a discrete project that would address a social issue or community group relevant to their garden. Ness targeted socially disadvantaged people in its catchment area. A group of students from Shorefields Technology College in Liverpool took part in a joint project where for six days, they swapped the urban classroom for the garden. The evaluation was done by RCMG (Reference 2)

Nancy has the most community gardens in France. While these gardens are generally designed at the initiative of associations or collectives of inhabitants, in Nancy, they are part of the urban development plans.
This demonstrates a real desire from the city to bring the inhabitants closer to sustainable development while providing them with the means to create greenery in the heart of the city (Ref. 1). The Plateau-de-Haye district, where green space was recently created, allowed the emergence of many plots (Ref. 2).

The project BEETE & BIENEN (Beds & Bees) in the Eastern part of Karlsruhe is an awarded sustainability experiment where garden beds, flower beds and beehives create a new urban greenspace for humans and animals and increase the urban bee population. Residents - in collaboration and under the guidance of gardeners – plant herbs, flowers, vegetables, fruits and trees that provide food for humans and thereby provide a natural habitat for the urban bee population to thrive. Residents shall take over ownership of maintenance and cultivation of the garden in the long run. (Ref. 1). The project is not about honey yield, but about enabling the bees to live as naturally as possible. Hives and garden beds are established in several small gardens in the city, including one Marstallgarten and another in Grötzingen. (Ref. 8)

The restoration of the Nesttun watercourse was made in order to secure the watercourse’s surroundings against damaging floods and to develop its urban qualities as a blue/green structure traversing this part of the city. The City of Bergen has exploited possibilities in flood control measures to develop the watercourse’s natural qualities and improve accessibility. A number of measures were completed in order to give the watercourse a positive ecological status and make it into an attractive recreation corridor, learning arena and secure ‘blue-green’ urban structure.
