Conduct a baseline survey before and after NBS implementation

It is one of the most famous parks in the city. A re-design is offering the opportunity to make use of the full potential of the place and to put it back into the public’s focus – as a place for recreation, a park, a promenade and Zurich’s very own, most central urban park. An urban square was formed, representing generosity and offering space for multiple functions. A gateway from park to courtyard during the daytime, the mirroring water surfaces of the illuminated pools, and the annex’s reflecting façade create the atmosphere of a grotto at night (Ref 1).

One of the largest green roof building sites in Switzerland, the new dispatch building at Kloten International Airport is Dock E. Previously known as Dock Midfield the building is situated between take-off runways and landing strips. The roof is sporting an extensive green roof measuring 4,000 m2 (43,056 sf). Dock Midfield represents a perfect example how green space can be regained on roofs. Completed in November 2002 after years of detailed discussions, the planning group decided to install ZinCo green roof systems. (Ref 1)

The Rohrschollen island, located near Strasbourg, is representative of a particular environment in Europe: the Rhine alluvial forests. These forests are known for the exuberance of their vegetation and their richness of species: it is a rare ecosystem both at the national and European level. These forests are regressing nowadays and as a result, the four major European rivers from the Alpine range (Rhine, Rhone, Danube, Po) have lost most of their riparian forests. The objective of the project is to restore a dynamic flood regime on the island of Rohrschollen that is modeled on the Rhine's hydrological rhythm (Ref. 1).

Under the “Bahn 2000” project while restructuring the main railway station of Zurich, a green roof has been implemented on one of the platforms. The whole area was mapped as a sensitive area, a living space for different endangered insects and reptiles whose natural environment consisted of desert-like spaces. Swiss law prohibits the destruction of such biotopes without replacement. In their protection, the idea of using the rooftop as a replacement was suggested and accepted by the administration. The roof was planned with a special focus on the living space demands of the different species. (Ref 1)

Baubotanik Tower is a test and demonstration building in Wald-Ruhestetten, approx. 150km south of Stuttgart. It exemplifies new engineering possibilities with living plants and visualizes the architectural and ecological potential of Baubotanik. Baubotanik or Living Plant Constructions is a technology of building with living trees, advanced by Stuttgart architect Ferdinand Ludwig. Baubotanik shapes living tree branches, stems and roots of trees into buildings to use qualities of forest in a dense city. For this purpose, living and non-living structural details are joined in a way they can grow together into a botanical and technical compound structure (ref 1, 2, 5).

The Project "Let's Open the Walls" is an integrated program of urban and social regeneration interventions that aimed to revitalize a portion of the Venice Commune (that is, one in the former neighbourhood Quartiere Due: Dorsoduro, Santa Marta, Giudecca, Santa Croce, San Basilio). The program, promoted by the City of Venice and funded by the Ministry of Infrastructure and Transport in 2004, provides for social inclusion and the weakest sections of the population and involved several interventions, including the planting of trees and the creation of green spaces for social activities. In particular, the Urban Italia program addressed to Venice is named: “Apriamo i Muri” (Opening the walls). It refers to the work-field “Quartiere 2” (District 2), in which are concentrated many actions that the city Administration has planned and approved during these last years. The Administration's objective was to transform and revitalize the degraded areas of the Venetian historical center, also through innovative actions. The program aims generally at urban, infrastructure and social regeneration of the Quartiere 2, moreover, it responds through articulated specific works to the critical complexity of the area.

INCREDIBLE EDIBLE (or "Incroyables Comestibles" in French) is an experiment of social innovation: the volunteers of the movement cultivate small vegetable gardens scattered in the cities and the countryside and make their products available free of charge (Ref. 1). This, the first intervention, took place in front of the "Epicerie du Coing" where volunteers planted several vegetables, flowers and plants (Ref. 2).

Grangetown is the site for a flagship environmental programme to tackle flood risk and water waste (ref 5). This scheme catches, cleans and diverts rainwater directly into the River Taff instead of pumping it over 8 kilometres to the sea. It will make Grangetown a greener, cleaner place and enhance local biodiversity (ref 2). Every year more than 40,000m³ of rainwater is diverted from entering the combined sewer network (ref 1). Interventions include planters, swales, bio-retention ponds, permeable paving and curb drainage, making use of the existing streetscape. 108 rain gardens have been created, and 130 trees have been planted; the area has been deemed the 1st "bicycle street" in Wales (ref 8). Wider benefits include education, health, well-being (ref 1).

Forests fulfil several important climate functions, they are carbon sinks, regulate the local climate or buffer heatwaves and cloudbursts. Based on climate projections, longer dry periods are to be expected during summer months which have major implications for local humid forests. The “fit for climate change” project was initiated to develop and implement climate adaptation measures for the latter, for instance via hydrological regulation, the use and reinstatement of resilient, adapted tree species or revitalizing moors and swamps. It was administered by the regional forestry authority and the nature conservation station Münster (Ref. 1 and 2).

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).
