Joint implementation (e.g. tree planting)

The Hanging Gardens of Jonfosse is a "nature garden". It is used to be a derelict area, but now the area is leased by the nature protection association Natagora to the SNCB-Holding as an opportunity to preserve the rich biodiversity of the place. Natagora uses the project as a teaching garden and they organize public visits during various events. They use the community's help for maintaining the area. In addition to the management, the gardeners usually meet on Saturday afternoons to maintain the plots (Ref. 1).

Situated next to Bebington railway station, the site is of biological importance within Wirral. This urban nature reserve was developed on a former railway sidings and is now an oasis of green tranquility in densely populated urban area; its industrial past has been put to good use as a home for wildlife (e.g. on the thin, nutrient there are now carpets of wild flowers, including wild carrot & occasional bee orchids). Up to 26 species of butterfly have been recorded here, with 18 species breeding on site - giving the park its rather apt name. (Ref. 1, 2)

New Ferry Butterfly Park has been awarded a Green Flag for the seventh year, which signifies that the space boasts the "highest possible environmental standards, is beautifully maintained and has excellent visitor facilities". (Ref. 12)

The municipality of Catania, in collaboration with the University of Catania promotes sustainable agricultural practices in specific areas of the city with the project “Urbanhort” (Uban Horticulture systems for Resilient, Efficient and Sustainable cities). The main focus of the project was placed on biological, indoor and vertical gardening. The main goal of the intervention is to give value to the territory, to increment tourism, culture and the environment. What wanted to be tested was the efficiency of the practice in terms of price, health outcomes and the promotion of a correct diet. (Ref.1.)

The project might still be ongoing, however, no information was found on the website of Catania's municipality or on the website of the University of Agriculture of Catania for a later date that can show the current stage of the project (as of July of 2020).

In 2014, local residents of the St. Pauli neighbourhood of Hamburg supported by architects decided to reshape the Hilldegarden bunker built during WW II. They managed to convince the owner of the bunker, who currently leases the rooms of the bunker to a nightclub, a music school, an instrument store and a photography studio, to re-create the bunker in a way that pays special attention to ecological and social aspects. (Reference 1-3). ”The new project would see the space continue its mixed-use atmosphere, but topped with a massive public rooftop garden with walking trails.” The 800 sqm garden will use sustainable techniques for its operation, including renewable energies and greywater collection for irrigation and will offer a public garden where residents can engage in urban food production. (Reference 2) In September 2020, the reconstruction of the bunker is still in its early phases. (Ref. 8)

As part of their school curriculum, engineering students from the engineering school "ESIGELEC" (École supérieure d'ingénieurs en génie électrique, in english Graduate School of Electrical Engineering) had to carry out a Project of Initiative and Creativity. They have chosen to build an indoor garden with an intergenerational component in the Lamauve retirement residence in Rouen in collaboration with Saint-Léon primary school (Ref. 1).

The Haumanngarten is a community garden in Essen founded by the Transition Town movement (Ref. 1). Since May 2015 a mixed group have been growing vegetables, herbs, flowers and berries on a former playground. Fellow gardeners with and without knowledge of gardening participate in the garden (Ref. 2).

The aim of the project is to restore the near-natural state of the Alster, the neighboring floodplains and side waters and thus support biodiversity, the recreational function of the riversides and promote environmental education (Reference 1). The implementation of the project began in 2012 and is planned to continue until 2021. It’s second phase started in 2018, which focuses on redeveloping the inner-city areas of the Alster. (Reference 8) The developers of the project focus on improving biodiversity and habitats. Recent nature conservation efforts included the installation of bee hotels, installation of gravel depots where fish lay eggs and the building of three fish ladders at the Poppenbüttler, Mellingburger and Wohldorfer locks, so that salmon, sea trout and sticklebacks can migrate there again. (Reference 6) In the future, other biotope structures in the urban river environment are to be improved. The project also provides opportunities for voluntary work and educational field trips for schoolchildren. (Reference 9)

The park, dedicated to the Sicilian judge assassinated by the mafia in the early 90s, was the object of a regeneration project by two associations (with the approval of the municipality). The initiative was practically implemented by kids of several schools in Catania, which were invited to the park with the intention of cleaning the area to make the spot available to new plants and trees. This is not just a natural intervention, it is of great cultural and social value for the importance of the character for the city and region. (Ref.1.)

Citizens have taken the initiative to create a community garden on an area where an abandoned building was located. With community engagement and support form public and private sector actors along with non-profit organisations, the garden was officially opened in 2011, bringing urban green space closer to the residents of the quarter. (1,2,3) The garden consists of recreational facilities, green space, a vegetable garden, fruit trees, a pond and activities are organized, which all largely contributes to social cohesion. The community has formed multiple groups that are responsible for parts of the community garden. (1)

Green space created behind Rock Ferry library on unused land. The plot of unused land, owned by the Wirral Council, signed a lease with the 'Grow Sow Well' project to run a volunteering scheme and sessions for the community (particularly aiming to help people with mental health issues). Grow Sow Well worked with residents, schools and community groups, bringing people together to celebrate their area and increase awareness of healthy eating and food production. (Ref. 1, 2) This lease has was transferred to the organisation called the Utopia Project (works with young people and includes horticulture). (Ref. 8)
