Collection of monitoring data at specific time intervals during the project to aid evaluation

The public awareness campaign 'flowers for bees' was initiated by the French Apidology Observatory (OFA) and has taken place each year since 2017 (Ref. 7). In 2017, 100 000 bags of honey-seed - whose flowers produce pollen and nectar - were distributed throughout the national territory of France on Tuesday 20 June as "one of the biggest mobilizations undertaken in a day in favor of a species threatened with extinction" (Ref. 5). The city of Marseille wished to associate itself with the event by organizing a plantation and a distribution of seeds". A total of 5,000 bags were distributed in the city from 20 to 23 June 2017 (Ref. 1).

Liège Trilogiport is a trimodal logistic area of ​​100 ha located along the Albert Canal, which includes a 15 ha container terminal and a ​​40 ha logistic area. From early stages of development, particular attention was paid to well-being and quality of life. A considerable effort was made to preserve about ¼ of the total area of ​​Liège Trilogiport as nature area, with more than 25 hectares dedicated to a green welcome zone (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).

The Development of the Garden of the Schloessel project is part of the Natural Urban Park project undertaken by the City Council in consultation with the Strasbourg Urban Community (Ref. 3). The project aims to reduce the carbon footprint of the area by installing and redeveloping green spaces in the garden as well as providing the site with stormwater management infiltration (Ref. 1).

On November 5, 2019, the Committee for Urban Development and Technology passed the building decision for the riverside park Austraße - Neckarterrassen. To the north of Münster, the Neckar has cut deeply into the shell limestone and describes a wide arc on the Prallufer. There is little space between the cliff and the river - that is what makes this place so special. This is where the Austraße riverside park is being built with the elements Freienstein water playground (element 1), Neckarterrassen and Tapach-Link (element 2) as well as Austraße, Neckarufer and Neckarstrand (element 3). The first component has already been implemented: children will find their favorite spot on the Freienstein water playground south of the Max-Eyth-Steg. Students from the Elise von König School in Münster contributed their ideas as part of a child participation program. With the second component and its sub-projects “Tapach-Link” and “Neckarterrassen”, there are beautiful prospects for Münster: Those who have overcome the relay to the Neckarterrassen can rest in the shade and let their eyes wander up and down the Neckar. The third component of the Austraße riverside park - in addition to the Freienstein water playground, Neckarterrassen and Tapach-Link - focuses on the banks: podiums and platforms are planned on the river to linger while the freighters transport their goods on the water. Insects, small crabs and small fish find optimal living conditions on the renatured bank zones with stones and diverse flora. (1, 7).

Landscape Park Neckar is a multi-place NBS intervention that is being realized along the banks of the river Neckar in 27 cities, including Stuttgart. Along the river axis, the free spaces between the dwelling buildings, industrial areas, and transport terminals are identified to be transformed into green areas, parks, and new recreational facilities. With this step-by-step approach, it succeeds in regenerating green areas for natural and social functions and helps drawing attention to the diverse benefits of Green Infrastructure. There are now eight master plans for the different landscape areas, which fit together like pieces of a puzzle to form the Stuttgart Region Landscape Park. Each sub-concept is tailored to the characteristic conditions. Since 2005 the Verband Region Stuttgart has been calling on cities and municipalities to submit project ideas. From this, the projects are selected in a competition in which the region pays up to 50 per cent of the costs. In this way, total investments in the Stuttgart Region Landscape Park of around 45 million euros have been triggered in recent years and around 200 projects have been co-financed by the region. The redevelopment of the landscape is in the ongoing phase. (ref. 1, 2, 7).

“Balne Lane Fields are an area of land close to the city centre of Wakefield. The site comprises of an area of nine hectares, which includes a former landfill site that has been restored to open green space. Part of the site is within a flood zone (Balne Beck).” “The field is popular with the local population for informal recreation. The potential to improve the variety of recreational uses, ecological value and environmental quality together with its links to both local communities and strategic greenspaces make it an important piece of green infrastructure in the City of Wakefield.” (Ref. 1)

The project involves the BBC Drama Village - a combination of studios and stores with associated offices and technical suites. It was the requirement for all buildings to achieve a BREEAM Excellent standard (ref 1). GreenBlue Urban structural RootCell systems were used for this development to create adequate tree root volumes, to ensure optimum tree establishment and growth in a demanding coastal location (ref 2). A Living Wall has been made which has a number of functions including the provision of a new home for solitary bees, lacewings and other invertebrates. A rainwater harvesting system has been installed (ref 1). Speaking generally, the studio, stores and office amounted to over 18,000 square meters and 900 new meters of HV, gas water drainage and telecoms (ref 1). Areas of eco-design include transportation, energy efficiency, water efficiency, materials, indoor environmental quality, waste reduction and biodiversity (ref 1).

The Vesdre River Greenway plan was intended to give the town of Verviers the opportunity to reconnect the local residents and businesses with the river and to create new functions, such as recreational and economic activities, around the river Vesdre. The development of the plan was part of a research project called VALUE, Valuing Attractive Landscapes in the Urban Economy, which was funded through the European Union Interreg IVB programme for North West Europe. It aimed to demonstrate the economic value of Green Investment (GI) at the site scale, showing how to target investments to maximise the competitive benefits to communities. "To serve this purpose, the Economic Development Agency of the Province of Liege in collaboration with the University of Liege planned developing a cycle and pedestrian path in the Pré-Javais District, near the city centre, on the left side of the Vesdre River in Verviers, linking the centre of Verviers to the suburbs" (Ref. 5). The green and blue infrastructure was planned to allow the creation of a true link between natural wildlife, inhabitants and businesses, and will offer a new development strategy for the whole town (Ref. 3).

Community Garden Trompenburg was initiated by one citizen who mobilized his neighbours to create a garden in which organic crops can grow. The garden promotes social cohesion and equity within the neighbourhood because citizens, as well as disadvantaged groups and children, work together on the maintenance of the garden. Furthermore, sustainable food production is promoted and taught to interested parties in the form of workshops. (1,3,7)
