River Main: Restoration and floodplain consolidation
The Fechenheimer Mainbogen is the largest undeveloped floodplain area in Frankfurt am Main and a special recreational area in the Frankfurt Green Belt Internal link. Today, the Main Arch is mainly used for agriculture, but still contains numerous relics of a typical floodplain landscape, such as smaller floodplain trees, meadows and wet bank areas. Since 2015, the curve of the Main has been transformed back into a near-natural meadow landscape with water, alluvial forests and meadows in several steps. Animals and plants are given new valuable habitats and places of retreat, and people are given attractive recreational spaces in nature (10).
Green Corridor on Platenstraße
Platenstrasse in the Ginnheim district of Frankfurt was laid out as a four-lane feeder in the 1960s. It leads through the settlement of the same name, which was formerly the housing area of the US armed forces. After their withdrawal in 1994, the settlement came into municipal ownership. Many large families, often with a migration background, moved in. Wild parking lots and storage spaces were created without any quality of stay. In 2000, discussion about the redesign of the Plattenstrasse started and in 2015 it was completely transformed into a green corridor. The street space was rearranged and the paved areas were reduced to the necessary extent. Sensitive planning and respect for the established structures helped to preserve the character of the district while significantly increasing the green area with recreational facilities. (1)
Eco-District Plateau de Haye
"This disctrict of "Plateau de Haye" is part of the EcoQuartier approach, is one of the most ambitious urban renewal projects. In line with the development of the New Urban Renewal Program, work was carried out this year [2012] on the challenges of opening up territory to its urban and forestry environment in order to confirm the "Forest City" approach initiated by the architect-town planner Alexandre Chemetoff" (Ref. 1). It received the EcoQuartier National Grand Prize (Ref. 2). A forest, community gardens and a green corridor are being developed with a rainwater recovery system (Ref. 2). Work is set to continue until 2024 (Ref. 10). "It will first allow work to be done on the functionalities of the district : development of spaces freed up by the demolition of the Blanc Sycamore and the Purple Beech, reconversion of the Tamaris and Ombelles into housing, shops and spaces dedicated to companies, creation of green spaces , shared gardens and parking" (Ref. 10).
Sainte Marie Park and Festival of Nature
Park Sainte-Marie is the second largest park in Nancy (Ref. 8). "The park Sainte-Marie hides varieties of splendid oaks and many other rare plants. It also hosts that annual "Nature in Festivities" event in the first weekend of May which represents the largest plant market in the region (Ref. 2). "This park was awarded the "Tourism and Handicap" labels in 2007 and "Outstanding Garden" in 2010" (Ref. 1). "An old Alsatian House , created for the International Exhibition of the East of France in 1909" is conserved within the park (Ref. 8).
Climate Innovation District
The district will initially incorporate 516 new low carbon homes alongside manufacturing, leisure, offices and climate-resilient public realm. (2) The overall approach to landscaping, amenity space and public realm in the scheme is to make use of sustainable drainage techniques, enhance the biodiversity value of the River Aire corridor, provide an appropriate level of landscaped publicly accessible open space, and contribute positively to the overall distinctive sense of place at the site.

Nancy's Charter for Trees
"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).
"Gallus Garden" Community Garden
In Frankfurt, the "Gallus Garden" is a community garden built in 2016, which not only impresses with its 1000 m2 size but also reflects the cultural diversity in the district (4). The garden was initiated by the Kinder im Zentrum Gallus association in collaboration with the Gallus neighbourhood management with the help of many sponsors and donors such as the Open Space Office and Deutsche Bank (4). The garden consists of two areas with raised bed for families, kindergarten groups and individuals to cultivate their food there, while a third area is for community events with fruit trees. The aim of the Gallus Garden is to create a community place where old and new residents of the area get together, can share knowledge and spend time in nature (4,8).
Rewetting Sandall Beat Wood
This intervention aimed to address low water levels and low water quality in the Sandall Beat Wood and Cantley Park. The problems have been identified by the council and this project was planned to improve the water levels as well as the water quality. This also helped in improving the gross water flow of the regions and protected the wetland habitats. In addition to the above-mentioned benefits, the project successfully engaged local communities. (Ref 2).
Glasgow Green Park
Glasgow Green is the largest park in central Glasgow with an area of 55 ha. The Glasgow Green renewal project was planned in order to restore the area from the disrepair and poor aesthetic quality to attractive, extensive open spaces, modern play facilities, spacious winter gardens, and historic people’s palace (Ref 1). The Glasgow Green renewal plan has been devised to restore Glasgow Green (including the People's Palace and Winter Gardens, Fleshers' Haugh and Richmond Park) to its original glory and create an improved visitor attraction. (Ref 3)
Ephemeral Gardens of Place Stanislas
An ephemeral garden has been set up in Stanislas Square each year since embellishment and pedestrianization works took place in 2005 (Ref. 2). The Parks and Gardens Department of the City of Nancy works around a topical theme, unveiled at the beginning of the summer: such as travel, history, or technology. The city imagines flowerbeds which cover up the square, with flowers and poetry. It is intended to offer visitors a new perspective on the square (Ref. 2). In 2015, the project's theme was "Connected Garden" combining technology and nature (Ref. 3).
