Community Garden Trompenburg was initiated by one citizen who mobilized his neighbours to create a garden in which organic crops can grow. The garden promotes social cohesion and equity within the neighbourhood because citizens, as well as disadvantaged groups and children, work together on the maintenance of the garden. Furthermore, sustainable food production is promoted and taught to interested parties in the form of workshops. (1,3,7)

B.Bylon Roof Park is a green park on top of the B.Amsterdam building which provides a healthy environment for employees and citizens of the neighbourhood. The park contains a vegetable garden, recreational facilities, meeting spots, sport facilities, a herb garden, a water basin, fruit trees, chickens and a restaurant (1,2,5,8). The roof park stores and uses storm water and an organic circular decomposing system provides plant nutrients. (4,7).

PopinnPark claimed to be the first indoor park of Europe and was created in an abandoned store, aiming at improving the quality of the neighbourhood and bringing nature closer to people. It became a meeting spot for communities, artists, businesses and citizens for exchanging knowledge on social/sustainability issues or for recreation. Popinn Park contained plants that improved air quality, local businesses that provide fair foods and drinks and nature-based art. (1)
After running for two years, Popinn Park closed and was transformed into an art gallery under the name of Popinn Art. Since 2018, Popinnart is an artist-run nomadic collective with over 25 contemporary artists. The art on offer is varied and qualitatively and conceptually challenging. There is a choice of spatial work, figurative and abstract, collages, photography, paintings, drawings, textiles and video. (5)

The initiative involves establishing beehives on the roofs of the Catholic University of Lublin and the Centre for the Meetings of Cultures. It seeks to provide the habitat for the bees in the city, help in pollination, educate the society about the bees and shape more ecologically-friendly attitudes among the students, faculty and visitors. It should also produce honey that can be sold or distributed free of charge, which can serve in a promotional tool of the two institutions. The Centre for the Meetings of Cultures has additionally opened a garden to provide food for the pollinators [1,2,3,4,6]. In 2020, the initiative is still ongoing and expanding. Every year, the university organizes a competition about the life of bees for various age groups [7].

In 2008, the wilderness experience garden and laboratory was founded on 2,500 sqm of nature area in Münster by Annika and Olaf Bader, two pedagogues. With grasslands, hedges, fruit trees, a treehouse, beehives, a yurt, a fireplace and many more elements it’s a place for nature experience and exploration for children and adults. Guests are encouraged to engage with nature scientifically, via play, arts or manually. Based on a hands-on approach, there are also vocational trainings for extracurricular education providers offered (ref. 1 and 3).

In 2008, a green wall of more than 500 m^2 using a hydroponic watering system was developed on the side of the Max Juvenal bridge. Designed by Patrick Blanc, french botanist and pioneer in the development of green walls, it is considered an "authentic work of art, which evolves over time and the seasons and contributes to "renaturing" the urban space" (Ref. 4, page 7). The wall is intended to illustrate the benefits that green walls can bring to the environment, such as the reduction of heat islands in urban areas and their contribution to cleaner air due to the production of oxygen and the reduction of CO2 rate by photosynthesis (Ref. 1).

It is the most extensive green roof in Lublin, designed to cover 16,700 square meters rooftop area of the shopping mall 'Castle Terraces' (Tarasy Zamkowe). Its purpose is to serve as a green recreational area for relaxation and public events, as well as an ecological solution for heat mitigation and water retention. The roof is divided into two parts: 1) an area accessible to the public with flower meadows, walking paths, viewing points from which the visitors can see Lublin’s old town 2) ‘intensive cultivation area’ with endemic trees, bushes and succulents which are not directly accessible to the public [1,2,3,8].

Urban gardening or gardening in the city is a form of agriculture that is about more than just producing food: community gardens involves also social, cultural and political components. It's about actively participating in urban development, creating new living spaces or making a contribution to biological diversity (ref. 3). The campus garden on a surface area of 1,200 sqm provided by the university was created by a group of students in 2013. It is open every day to everyone interested in gardening and serves as a place for recreation and exchange for students of different disciplines and citizens. Apart from herbs, vegetables and fruits, also flowers are planted. Seeds and materials used as plant beds, such as tires or rice bags are often donated from the city or local businesses (ref. 3 and 4).

Appletree is an outdoor community resource, where people of all ages and from all walks of life, get together to grow e.g. fruit, and contribute to developing and maintaining the area. The growing space and garden are divided into different areas, offering a range of gardening experience. The community also contributes to their permaculture, wildlife and wildflower areas. The community is constantly planting and regenerating areas of the garden. (Ref. 1)

The Polder Roof is a green roof originally installed on the top of the Old School Amsterdam, Gaasterlandstraat, Amsterdam with innovative controllable water storage and drainage system on which crops are grown, solar panels are installed and that provides space for recreation. (1,2) Thereby, it combines multiple benefits including the reduction of heat stress, noise reduction, sustainable energy provision, biodiversity, food production and climate change adaptation (2,7). The Polder Roof was a pilot project that won an innovation award and is viewed as an example for urban climate change adaptation solutions. (2).

In 2019, due to the renovation of the former Old School building, it was necessary to relocate the Polder roof to a different place. The Polder Roof is a completely de-mountable system, made up of crates with a sedum layer on top, thus it could be removed quite easily from the Old School roof and put somewhere else. In the name of circularity, the sustainable drainage system was moved to the roof of the South Food Bank building. (10,11,12) With the relocation of the Polder Roof system, however, the size of the green roof has decreased to 1200 sqm from 2010 sqm (2).
