Preserving biodiversity in Conservatoire des Restanques
"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).
The Bizardin community garden
The Bizardin is the community garden of Hellemmes, created by the association AJOnc (Amis des Jardins Ouverts et néanmoins clôturés) on the initiative of a group of inhabitants. Managed by the locals, it gives life to the neighborhood where children like to play, watch insects, sow radishes, watch for frogs. A living garden where wild and cultivated plants come together and create a floristic richness often unsuspected by the simple passer-by, a result of many years of work. It is also an ideal place to observe as insects and birds swarm. (Ref 1)
Green My City
The Toulouse based project Green My City is a community collective focused on promoting sustainable consumption and creating a sustainable environment, (Ref. 2) It anticipates constructing thousands of square meters of organic vegetable gardens on the roofs of the city of Toulouse, saving 50 tons of CO2 emissions per year. The project defines itself as a prospective tool, which intervenes in the stream of gardening initiatives: it maps, selects, and then accompanies the initiatives (Ref. 1). The project supports the realisation of environmental initiatives by engaging citizens, communities, businesses and designers to help create an urban oasis (Ref. 23).
The water garden at Haute Deule River Banks
The development of the sustainable district of the Haute Deûle River Banks, associated to Euratechnologies TIC center, leans on recognition of water as an element of its foundation. The current innovation is about the water garden. It is a part of the bigger project, building an eco-district on the banks of the Haute Deule river. The water garden, which plays the role of storage (stormwater) and of phytoremediator, evolves with the rhythm of rain and becomes the emblematic place for this work with water. Its vegetation improves every year and the natural seeds of young willow trees contribute to the establishment of a dynamic ecosystem (Ref 1).
Kletterfix - Green Walls for Leipzig
Together with the Office for Urban Greenery and Waters of the City of Leipzig, the charitable association Ökolöwe Leipzig started the green facades initiative "Kletterfix - Green Walls for Leipzig" in 2015. The project aims at creating awareness about the multiple benefits of urban green walls and inspiring action of tenants and landlords on private property. As a measure mandated by the Urban Clean Air Plan, green facades improve the urban microclimate, general living conditions and combat particulate matter pollution. On-site advice about suitable plants and maintenance is provided upon application and respective seeds for up to 5 plants are sent for free to the applicants by the city department (1, 3, 7).
Nottingham in Bloom
“The Nottingham in Bloom campaign is a city-wide partnership which includes residents, businesses, schools, community groups and a wide range of volunteers. The aim is to encourage more people to get involved to improve their local area. Together they [through the campaign] produce horticultural excellence and enhance the local landscape, the environment and the character of Nottingham.” (Ref. 1)
Arkwright Meadows Community Gardens
Arkwright Meadows Community (AMC) Garden is situated in the heart of inner city Nottingham, Prior to 2001, the site was a disused, derelict and rubbish-strewn piece of land. In 2001, a group of Meadows residents came together to improve this derelict piece of land and work started to create the infrastructure of the community garden. The area was transformed into a green oasis and outdoor learning environment. (ref. 8)
Citizen Farm
Citizen Farm was a start-up founded by Pierre Osswald (Ref. 3). The project began with an experimental urban farm in a vegetable garden of Raymond 6. The ozarium farm (a vegetable aquarium) uses a technique called aquaponia (Ref. 5). This technique grows all kinds of plants and vegetables indoors in an entirely natural way. Fertilizer or watering are not needed. Plants feed on the nutrients in the aquarium: water and fish discharges. In return, they purify and oxygenate fish water. It is an ecological and educational innovation which is surfacing as an "eco-responsible" trend. (Ref. 1, 2). The Citizen farm initative was ended in 2018 due to financial difficulties (Ref. 35).
Annalinde community garden, nursery and fruit orchard
The ANNALINDE gGmbH operates multifunctional urban agriculture and demonstration projects in the Western part of Leipzig: a community garden, a nursery and a fruit garden on a former train station where the emphasis is on community development and mutual learning processes in addition to food production. This is safeguarded by an events portfolio consisting of garden working days, workshops and collaborations with schools, kindergartens and like-minded organizations. In addition to that, open urban labs are operated for a number of initiatives and projects covering subject areas like urban agriculture, recycling, composting, urban bees, urban resilience and sustainable urban development (1).
Transformation of abandoned land into neighborhood garden
After being abandoned for more than 10 years following the collapse of a building, a piece of land inside the city's "Le Panier" district was approved by the city in 2017 to become a "neighborhood garden" combining green space and a community vegetable garden (Ref. 1). After many delays the project was completed in early 2020 and the garden opened on February 28, 2020 (Ref. 11). The district "Le Panier" (where this intervention occurs) attracts many tourists every year for the charm of its narrow streets and colorful facades (Ref. 1).
