Improved soil quality

"On June 1st 2017, Saint-Etienne Métropole officially committed itself to the implementation of measures to promote the circulation of wildlife between the different green spaces with important biodiversity in its territory" (Ref. 3). "Saint-Etienne Métropole has signed with 13 partners a new contract called "green and blue". It is a new blue and green framework for the whole territory, a regulatory tool for the protection of biodiversity" (Ref. 2). "It aims to continue and reinforce the actions already undertaken with a transversal and urban dimension" (Ref. 2).

"The National Park of Circeo, established in 1934, on the Tyrrhenian coast south of Rome, contains ecosystems of invaluable scientific interest. The site is, however, regularly invaded, during the summer season, by thousands of holidaymakers who tend to
park their cars on the sand dunes near the beach with a consequent heavy impact on the whole dune system. The LIFE project aimed to complete the preventative and natural restoration measures started under two earlier projects financed by the EU" (1).

The Edinburgh Living Landscape (ELL) is a partnership between the Scottish Wildlife Trust, the City of Edinburgh Council, Edinburgh and Lothians Greenspace Trust (EGLT), the Royal Botanic Garden Edinburgh, Green Surge and Edinburgh University, it aims to help make Edinburgh a city fit for the future by fashioning healthy and beautiful environments that are resilient to climate change as well as being highly valued and accessible to people. It is made up of a range of projects that will create, restore and connect green areas of the city to make attractive and biodiverse landscapes that are enjoyed by residents and visitors. One of the examples is the Holyrood park. Naturalisation was tested in Holyrood Park, where a once regularly mown grassland is now cut only once per year. It benefits both wildlife and public amenity and also reduces maintenance costs for the site, with the potential to spend elsewhere on greenspace maintenance. This is a part of the ongoing Edinburgh Living Landscape Case Study which aims to make Edinburgh a city with healthy and beautiful environments, resilient to climate change. A range of similar projects will create, restore and connect green areas of the city to make an attractive and biodiverse landscape (ref 2, 3).

"In order to make this center area attractive and dynamic, the EPASE (Saint-Etienne Public Development Agency) and the town hall of Saint-Etienne have set up an ambitious eco-neighborhood project. This project is based on public spaces that are built on an original urban park model where nature is the driving force behind the site. Nature is at the heart of this "park city" project, realized in record time: in a year and a half, the vast majority of the park's work has been carried out and the neighborhood has begun to change."(Ref. 1)

Love Square is a combination of nature and wildlife with a social space for residents and workers. The area has wildflower meadows, lawns and a mini wetland lined with bird-friendly trees (ref 2). Love Square is one of the examples of a new type of ‘smart’ -urban eco-park, combining nature and wildlife with artworks, social and activity spaces. It has a ‘Rain Garden’ and mini wetland that will soak up excess rainwater. It is a prime example of ‘water-sensitive Urban Design (ref1). The rain garden is designed to provide essential urban “greening”; increased soil and vegetation coverage will be able to soak up extra rainfall after a storm, will help to reduce the danger of flash flooding (ref 5).

The park of "Bois d'Avaize", with an area of 30 ha, is located south-east of Saint-Étienne on a hill site between 540 and 640 m altitude. A former mining site, operated from the 15th century until 1931, it was gradually reclaimed by vegetation before being converted into a municipal park in 1996 (Ref. 1). In 2016, the site was selected for the development of a project to enhance biodiversity by creating of a conservatory orchard, increasing amphibian-friendly habitats (with creation of ponds), and improving the connection of the park with the Pilat massif (a mountainous area) (Ref. 1). It is classified with the label "Natura 2000" for the conservation of natural environments for the richness of its fauna and flora (Ref. 1). Work was undertaken between 2017-2018 with management and monitoring set to occur from 2018-2050 (Ref. 1).

The Community Supported Agriculture initiative in Bonn (SoLaWi Bonn) is an economically motivated arrangement between consumers, farm businesses and certified gardeners to improve the urban provision of local, organic food. Together they develop a concept for collaboration where the consumer group commits to pay an annual fee to cover all of the farmer's expenses for production (according to individual financial capabilities) and to work placements at the farm per year. In exchange, the customer members of the initiative receive a variety of fresh, seasonal, locally produced vegetables. The farmers profit from financial security and economic stability and the ability to apply environmental friendly agriculture practices without the pressure of the market economy (1,4).

The lagoon has a great local significance for its biodiversity with the presence of certain species of rare birds regularly stationed in this area. Much of the biotope was degraded in the last decade by systematic embankments, constructions, as well as the inconvenience caused by various man-made pressures. A project was developed to reconstruct the area within the framework of a collaboration of the Institute of Marine Biological Resources, Inland Waters of HCMR, and Hellenic Ornology Company. The project offers directions for completing a protected region and proposes specific projects and actions of scientific monitoring, ecological rehabilitation, regeneration, and promotion. (Ref 3)

The agriparc of the Mas Nouguier is an agricultural reserve entirely maintained by the city of Montpellier. Conducted in organic agriculture, the estate contributes to the preservation of the identity of the territory and to the valorization of the living environment. Accessible to all, it offers a beautiful walk in the middle of the vineyards. Apiaries are used to develop educational workshops and to collect honey with school children. Olive trees, centennial pines and a large meadow come to embellish this little bit of countryside in town (Ref. 1).

The revitalisation of the park Gaštanica Koliba in Bratislava Nove Mesto is intended to stop the degradation of its ecosystem, preserving existing vegetation while improving the local climate and efficient use of rainwater. Over 100 trees were treated, including some of the local population of chestnut trees. A local seepage pit was installed to retain water both to the benefit of the local vegetation as well as to prevent erosion and landslides. The park has also been fitted with recreational facilities and is now illuminated to improve its accessibility for the local population. (7, 8, 9)
