Soil quality improvement

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 Desjoyaux ZAC in the Crêt-de-Roc district, was created in 2005. Since then, this three-and-a-half-hectare site, which is involved in the process of receiving the "eco-district" national label certification since 2015, has metamorphosed (Ref. 1). Some works aim to renew and embellish the public spaces located near the residences of the street and the impasse Desjoyaux to preserve biodiversity in the city center of Saint Etienne and for the well-being of citizens. (Ref. 1, 2 and 3). Community gardens, park, ephemeral gardens, swales and sustainable water filtration system are being developed in this project (Ref. 1, 2 and 3).

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)

"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 "PROSIT" project aimed at undertaking a series of actions based on environmentally compatible mechanisms to protect and recover the coastal rural territory of Cinque Terre. Today, the terraced landscape is characterised by intense processes of land abandonment and disuse, caused both by practical and economic difficulties of maintenance and by social changes. There is a risk that the damage caused by land abandonment can compromise the area's delicate hydrogeological balance, especially in an area where landslides and floods are highly common (1). A demonstration project to recover abandoned terraces was carried out in five areas of the park (1).

"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)

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 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 landscape in the Bielefeld agglomeration is exposed to stress from high settlement pressure and expansion of the infrastructure as well as in parts of intensive agricultural use (2). Since 2003, the Senne and neighbouring areas of the Teutoburg Forest which is protected under the Europe-wide protected area system, Natura 2000, become part of the funding program of the Federal Agency for Nature Conservation (BfN) and become one of Agency's Large-scale nature conservation projects (NGP) (2, 5,13).
The project area lies in the transition area between two major German landscapes: the Senne as part of the north-west German lowlands and the Teutoburg Forest as part of the Central European low mountain range. The juxtaposition and close interlocking of numerous habitats such as species-rich beech forests, remains of acidic deciduous mixed forests, dry and humid heathland or natural sandy streams form the basis for diverse flora and fauna. Many of the numerous rare plant and animal species are rarely found in North Rhine-Westphalia outside of the NGP area (13).

The natural area complex Senne and Teutoburg Forest was declared by the Federal Agency for Nature Conservation (BfN) to be one of the 30 hotspots of biological diversity in Germany due to its nationwide uniqueness ( overview map ). These “Treasure Chests of Nature” (BfN 2015) distinguish regions in Germany that have a particularly high density and diversity of characteristic habitats, species and populations.(13)
The NGP was funded by the Federal Republic of Germany, the State of North Rhine-Westphalia with contribution of participating municipalities and the North Rhine-Westphalia Foundation (13). The Teutoburg Forest / Eggegebirge Nature Park is also sponsoring the project (12).

"The HUERTAS LIFE KM0 project aims to recover the natural peri-urban Gardens of Zaragoza through the promotion of a ‘zero kilometre’ (km0) concept of local agricultural production. It expects to demonstrate a successful approach for implementing the European Territorial Strategy (ETS), delivering economic, social, health and environmental benefits. " (ref 4) in peri-urban green areas that have been neglected (Ref. 4).
