The park of Dondaines is an agro-urban park of the city. This contrast is guaranteed by the ecological management of space that aims to promote biodiversity in this highly urbanized area. The Park of Dondaines is located in a strategic position, between the old and the new Lille, and creates a link between these two entities. The park hosts a pedagogical farm. It is a framework where the urban, the animals and the plants meet. It preserves plants and small animals by providing them with food and habitat. The cover of the periphery, planted with pines, ensures the continuity of the park with the new districts of Euralille(Ref 3).The place is a garden of representation, park of proximity, urban agriculture and food production space, pedagogical farm and event platform, and a place for sports and games (Ref 2, 5).

The Garden of (Re) Finds, was born in Lille in 1997. It is the first "community garden", directly inspired by the model of the gardens New York, which was created in France (Ref 1). There is an organic vegetable garden, a scented hill, a rainwater harvesting system, a regional hedge of regional species, a compost corner and a convivial shelter in corded wood and vegetal roof (Ref 2).

Since the decay of the former DDR, the lignite industry had a major downturn. Most of the mines were closed and its remaining craters re-naturalized and flooded with ground- or rainwater to be revived as recreational lakes. In the Leipzig area of "Neuseenland" up to 23 artificial lakes were created since the nineties by the respective mining company "Lausitzer und Mitteldeutsche Bergbau-Verwaltungsgesellschaft mbH" which has the obligation to securely and sustainably redevelop the area into forestry, agricultural, natural or recreational areas and reintegrate it into the adjacent landscape. The lakes have become important recreational areas for citizens (4, 8).

Opened in June 2006, the Jean-Baptiste Lebas Park, which occupies a space once used for illegal parking and marred by 11 lanes of traffic, is surrounded by the boulevard of the same name. This park plays an important role in creating an urban green space into a derelict grey area. The park helped to increase the biodiversity of the area. It has an area of 3-hectare (7-acre) and it contains a large lawn with flowerbeds, play areas for children and places for playing "boules" (Ref 1).

While Hamburg has already had an impressive green infrastructure, it is now (since 2013) implementing an interconnected green network that will cover the 40 % of its area and support commuting by bicycle, recreation and climate change resilience. The project is planned to be completed by 2034. (Reference 9) The project aims to connect the two green belts, parks, recreational areas, cemeteries and animal habitats to each other with green paths and with the already existing “green axes” leading from the agglomeration to the urban core. The green network could not only absorb more CO2 but also prevent flooding by soaking up an increased amount of rain- and seawater caused by storms. (Reference 1, 2). An extensive network of cycle paths is also being built as part of the project. (Reference 2)

According to City Hall, the project revitalized a neglected green area and cleaned the local ponds to create an outdoor recreational space for the citizens and school children. It aimed to develop a new park infrastructure, plant new and protect the existing greenery, and purify the water to improve the ecosystem and provide healthier habitat for water and land species in a slowly decaying area. The ponds were utilized for recreation for the local community in the past [1,4].

The restoration of Highfields Park was completed in Summer 2018 with path repairs and tree works to be carried out in winter 2018 to 2019. The five-year development journey of returning Highfields park to its former glory has included two rounds of public consultation. The views of park users and project partners such as the University of Nottingham, the UK's Environment Agency and the Highfields Park User Group identified a strong desire to see the park restored and improved (ref. 1), including improvements on heritage features such as historic walls, bridges and the old Boating Lake Ticket Office (ref. 2). In total, this project aimed to repair unused structures of the park including walled gardens, gardener’s cottages and historic halls and houses, converting them into volunteer and training centers, event spaces and community facilities (ref. 3). Highfields Park also provides valuable scrub and woodland habitat for breeding birds such as robin, sparrow and blue tit. The additional diversity of habitats provides important foraging and breeding opportunities for invertebrates and mammals. (Ref 4)

Within the territory of the Region of Attica there are more than 100 wetlands including streams and their estuaries, coastal marshes and lagoons, lakes and constructed wetlands. They constitute “biodiversity islands” within a broadly degraded environment and offer the inhabitants of the Attica Region the opportunity to stay in touch with nature. A strategy and an action plan were developed for the conservation and restoration of these ecosystems in fighting climate change within the EU-funded OrientGate transnational co-operation project. (Ref. 1)
Climate Change is expected to put additional pressure on these habitats as, based on future climate projections, Attica’s vulnerability to drought is expected to rise from low to moderate by the year 2100. Drought episodes are expected to last longer and occur more frequently than in the past. This phenomenon is expected to have a serious impact on Attica wetlands as most of them are rain-fed. (Ref. 1)

In 2016, the project facilitated the revitalization and development of green areas in Dąbie (by an urban part of the Vistula River) to create the Dąbie Park. The park had been a neglected vacant green space with randomly scattered former playground facilities. The initiative involved greenery management and creation (bushes, trees, flower meadows), building new sports facilities (running/cycling paths, a basketball field), new infrastructural solutions (new water drainage system, a viewpoint) and creating a safe and modern space for children in a playground surrounded by large trees which provide shadow. The modernization and revitalization of the park infrastructure and local greenery have made the green riverbank area accessible to the public [1,4,5].

The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).
