Improved soil quality

"The garden was created in 2012 with the Parenthesis Association. The association closed in 2015. In January 2016 a group of gardeners decided to create a new association to continue their garden, that is when the gardens of Fontgiève were born. In the garden one discusses, one shares, one exchanges, one helps one, one gives oneself advice. The garden produces much more than vegetables and fruits; Ideas germinate there, sharing them is collective intelligence" (Ref.1).

The Bio Washing Machine is a combination of an Aquifer Thermal Heat Storage (ATES) system and biological natural attenuation of groundwater and is thereby mainly focused on groundwater decontamination and energy storage. The ATES system accelerates the biological degradation of groundwater contamination and provides sustainable energy because cold water is pumped through buildings during the summer to cool the buildings and hot water during winter for heating. The groundwater decontamination measurements are aimed at protecting water in order to provide safe drinking water (ref. 1, 2, 3)

"The desire to integrate trees in the heart of Nancy constitutes a long-standing commitment. The first Charter for Trees of Nancy was signed in 1996. Plant diversity was strengthened and the protection of trees accentuated, in particular thanks to the requirements of the Local Urban Planning. In 2013, the new version of the Charter will make it possible to engage all the actors of urban policy to increase protection of the tree, to be vital to biodiversity and to the quality of the living environment" (Ref. 1). "New legal, urban, ecological and social issues have emerged. The old charter now requires improvements in the face of certain evolutions. It was decided to renew it. This new document is in line with the previous one and faces the new issues of the trees in the city" (Ref. 1, p 9).

A project of 200 plots for an urban orchard on-site at Parque de las Aguas was created, where individual citizens, social groups, and companies can rent the lots to cultivate their own produce. The orchards hold educational programming for patrons and visitors as well. (Ref. 1,2,4)

The Paul Verlaine Garden received the "EcoJardin"(Eco-Garden) label in 2014 (Ref. 2). The EcoJardin repository is intended to be a methodological tool to guide good practices for gardeners and managers of green spaces (Ref. 6)."This garden is labeled as "Tourisme et Handicap". Work has been done so that this place takes particular account of the accessibility to the people with reduced mobility and the visually impaired. The Jardin Paul Garden is a succession of environments and vegetation architectures" (Ref. 1). At the entrance of the park, there is a playground, a garden of le Petit Poucet, and further the forest of birches, vegetable garden and the garden of tall grasses (Ref. 1).

The Wetlands uses natural processes for water treatment and involved local communities in the regeneration of the area. The
Wetlands were constructed in 2005 by diverting a small flow of Chellow Dene Beck through a constructed wetland designed to improve the appearance, water quality and biodiversity of the site. It consists of a series of ponds at the lower end of the site that acts together to remove impurities from the water before returning it to the beck further downstream. The creation of wetlands and maintenance is also a part of the larger Bradford beck project. (reference 1) The site is also used as a recreational trail for the local people and tourists (ref 4). As the reservoir is a local recreational centre it also promotes (paid) recreational fishing activities in some designated spots (ref 5).

The sustainable garden was created in 2013. Based on the gold award-winning RHS flower show entry in 2012 by the university’s ‘water@leeds’, the garden is an excellent example of collaborative working between the Facilities Directorate, Leeds University Union and academic staff. The garden provides a multi-functional space for staff, students and visitors to campus to enjoy quiet contemplation but also to cultivate an allotment-and-forest-style edible garden. It is a great example of a functioning ecosystem with wildflower areas, soft fruit hedgerows, insect houses and pocket habitats. (1)

The Mab Lane Community Woodland was planted on a former playing field at Mab lane and Croxdale Road West in Liverpool. It is a part of the larger Mersey Forest initiative which has been increasing the amount of woodland and green spaces across Cheshire and Merseyside since 1991.
The new woodland which has a network of native trees, wildflower meadows a community orchard as well as seasonal wetland areas and footpaths, was officially opened by the local community in 2010. It also includes new pathways for walkers and cyclists and areas for family picnics (Ref. 2, 10). Mab Lane Community Woodland is a partnership project involving the Forestry Commission, Northwest Development Agency, Mersey Forest, Big Lottery, Riverside Group, Liverpool City Council and the Local Community (Ref. 10).

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).

In 2007 the Lisboa City Hall began the development of a strategy for urban agriculture, having created in 2011 several allotment parks. Beyond the provision of plots, the Council also provided the fences, shelters for storage, water irrigation, training and technical support. In 2011 there were already 56 plots of 150 m2 at a location named Granja Farm (2)
