Sustainable consumption

The Strasbourg Grandeur Nature Plan is engineered by Strasbourg Metropole and is focused on optimising the actions and resources and resources of local authorities in the maintenance of local biodiversity and improving the living environment (Ref. 7). It combines with local associations and citizens through organising interfaces (e.g. workshops, online tools) that allow relevant local authorities to engage with local projects and make interventions on the basis of proposals made by the community. The project aims at improving the maintenance and development of green spaces and biodiversity due to the environmental issues surrounding urban sprawls (Ref. 4).

The Danube Eco-District project is Strasbourg's first eco-districy and is based on previous experimental designs in sustainable urban living (Ref. 27, 30). It is situated at the heart of the axis Deux Rives, and is thus a strategic point of the large Franco-German Deux Rives project (Ref. 28). The district will have the capacity for 20,000 residents, and will include green spaces, green roofs, insect hotels (Ref. 1), various water management facilities (ditches, swales... etc.), and composting facilities (Ref. 4). The project aims to improve biodiversity, social equality, ecology, reduce urban heating, and promote sustainable consumption (Ref. 30).

The medieval style Shared Garden Of Sainte-Madeleine Place development - situated in between two nearby schools - in 2009 was quickly claimed by the Association des Habitants Bourse Austerlitz Krutenau (Association of Inhabitants Bourse-Austerlitz-Krutenau) (AHBAK) neighborhood association because of its historic environment. The project turned the space into a shared garden, involving a collective composting area for organic waste, installing a rainwater recuperator, and planting local plant and vegetable species and new trees (Ref. 1, 2, 3).

The NBS is a socio-ecological initiative to create an urban garden that would serve as an outdoor space for creative endeavours in the Cracow's district Podgórze. The project was implemented by an association of cultural institutions, NGOs, artists' groups, landscape architects, social activists, cultural animators and artisans, who also activated a group of volunteers from among the residents. The initiative involves several activities including greenery planting, horticulture/vegetable garden, ecological education and art workshops. Space is rented from the municipality as an act of protection of naturalistic landscape from over investment and new residential buildings in the area. It is surrounded by modern developments [1,3,4].
The social garden was established in 2013 and it is still functioning with its original purpose [3].

This NBS is a part of the "Horta à Porta" (allotments at the door) programme which enhances the economic, environmental and social dynamics of the Porto region through the creation of community organic gardens and the promotion of active involvement which empowers local people and institutions. The program is led by the Greater Porto Metropolitan Waste Management Service, LIPOR. Implementation of vegetable gardens began in 2003. In the Metropolitan Region of Porto, there are 23 of these community gardens totalling four hectares, and the forecast is for a large-scale increase in the near future(1)

The Eco-District at the Banks of the Bohrie Ostwald is structured around water with the Bohren pond, the river Ostwaldergraben and the seasonal and permanent wetlands (Ref. 2). The project covers 50 hectares and was initiated by Strasbourg Eurométropole with 2 developers: CM CIC SAREST and Nexity-Foncier Conseil (Ref. 1, 7). The district will integrate its structures into the surrounding water land and vegetation to provide for agricultural water management and flood preventing procedures (Ref. 2). It will also have green roofs, public green spaces, (Ref. 4) vegetable gardens, (Ref. 7) and composting, while on-site vegetation will participate in the deployment of green infrastructure (Ref. 5). "An eco-district of 48 hectares (17 urbanized hectares) is being created" (Ref. 11).

With spaces for biodiversity being continuously threatened by urban development, the environmental association Ökolöwe Leipzig initiated a biodiversity-enhancing project during the 100th Catholic Day event in Leipzig in May 2016. Consisting of green interventions at four schoolyards all over Leipzig involving the active collaboration of students who are also expected to maintain the interventions into the future and 100 mobile high beds at the central city square for public display, the project objective was to demonstrate how to foster biodiversity even in limited urban spaces while also to raise awareness (1, 3).

"The Conservatoire des Restanques is dedicated to preserving biodiversity (conservation orchard, forgotten vegetable garden, Mediterranean garden with the typical plant species of low limestone Provence) and to be a showcase of the current considerations of Sustainable Development (energy, waste management, water resources management, etc.). The development of the site and the different elements of the landscape make it possible to develop educational programs on the themes of flora diversity, wildlife, heritage conservation, food, consumption and health, eco-construction and energy management" (Ref. 3).

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)
