The Republic Services Garden
The Republic Services Garden is a one-acre garden created and located in Hance Park, a large urban park located in downtown Phoenix, Arizona. As part of the larger revitalization of the park, the garden was created to showcase native desert plants, recycled materials, and shaded seating, serving as a model for eco-friendly urban landscaping. Its key goals are to enhance the park's appeal, create a welcoming community space, and demonstrate the potential of sustainable design in cities. By blending nature with urban infrastructure, the garden helps mitigate the urban heat island effect, addresses water scarcity, and supports habitat restoration. The project is a collaboration between the City of Phoenix and the Phoenix Parks and Recreation Department, with financial backing from Republic Services, the second-largest waste disposal company in the U.S. (Refs. 1, 5, 7, 12, 15).
Trénnelle-Citron Experimental Garden
Trénelle-Citron, located north of downtown Fort-de-France and separated by the city bypass, La Rocade, was originally established in the 1940s by Black Martinicans migrating from rural areas. Today, the neighborhood faces significant economic and social challenges. In 2016, young residents from the neighborhood alongside a local NGO launched a grassroots initiative to improve their community. They transformed a former municipal quarry, which had deteriorated into an informal dump, into a thriving shared urban garden, benefiting the local population. This project, based on traditional ecological gardening techniques and the cultivation of native crops, aimed to revitalize Trénelle-Citron—a densely populated area grappling with social exclusion, a shortage of green spaces, and limited economic opportunities for its youth (Ref 2).
The garden, developed on municipal land with guidance from the Ypiranga Martinique NGO, support from the local school, and collaboration from various stakeholders, now plays a vital role in the area. It raises awareness about agroecology, offers socioeconomic opportunities, promotes healthier lifestyles, and fosters social connections among residents. Spanning approximately 1,000 m², the site includes an office, a covered area, tool storage containers, market garden plots, a composting area, and a chicken coop managed by a local resident (Ref 7). In Martinique, such shared urban gardens are increasingly seen as important tools for sustainable development (Ref 5).

A wood for the city: the urban forest of Mount Urpinu
In the city of Cagliari, in the location of Mount Urpinu, 6400 new trees have been planted. The project, initiated in 2022, sought to restore the area's biodiversity and to revitalize the park for the benefits of the citizens (Refs. 1, 3 & 8). In fact, in previous years, the park has been subject to various environmental and social hazards because of its conditions: the area has been subject to wildfires and abandoned wastes, and with time, it became a gathering point for drug addicts and homeless people, thus becoming unsafe for citizens and especially for children (Refs. 1 & 6).
Therefore, the Metropolitan City of Cagliari decided to reclaim the area and plant thousands of trees of various species (holm oaks, oaks, pine, carob and olive trees) over more than 6 hectares of land (Refs. 3 & 8). The project's goal is to restore biodiversity, mitigate temperatures, decrease air pollution, and increase citizens' sense of community (Ref. 1).

Grangegorman Community Garden
The Grangegorman Community Garden is a collaborative project involving several stakeholders in restoring a neglected space within the TU Dublin campus and transforming it into a community garden. The project emerged from a partnership between academic and service departments of the university, a primary school, a land development agency, a multinational organization, and a property estate agent.
The project's ultimate goal is to establish a permanent community garden with strong investment, ensuring ongoing support for current users and welcoming a new, diverse group of participants. (1,6)
Launched at the start of 2024, the project focuses on rejuvenating the space, with restoration efforts continuing until December 2024. The garden features four allotment-style beds separated by gravel paths and is surrounded by 12 foliage beds (Ref 1). The initiative aims to provide educational opportunities centered on sustainability and horticulture, while also developing a sustainable, collaborative governance framework for the garden (Ref 6). It aligns with various national, local, and inter-organizational frameworks, strategies, and plans related to community engagement, biodiversity, and climate action (Ref 1).

Living Wall at the New Street Train Station
Air pollution is one of the most pressing sustainability challenges in the UK, with particulate levels exceeding both WHO guidelines and EU safe limits in many cities (Ref 6). In 2014, Birmingham was identified by the WHO as one of nine UK cities breaching air pollution safety guidelines (Ref 2, 3).
In 2012, a soil-based green wall was installed at Birmingham New Street Train Station as part of a project aimed at improving air quality, as diesel train services contribute significantly to nitrogen oxide (NOx) pollution. However, most of the plants did not survive. In 2017, Network Rail commissioned a private company to reconstruct the wall using a hydroponic system (Ref 3). The new green wall was installed in 2018 and completed in May 2019 (Ref 1, 3).
This hydroponic green wall not only enhances the urban environment with calming green infrastructure, but also helps mitigate air pollution and promotes biodiversity with the addition of 16,600 plants (Ref 1, 2, 3).

Bangkok City Farm
Due to the growing population density and extreme climate events in Bangkok, Thailand, food security has become a more and more pressing issue for urban people. As a response, the Bangkok City Farm project was launched in 2010 by the Food and Nutrition Programme of the National Health Promotion Foundation. Implemented in collaboration with the Sustainable Agriculture Foundation Thailand (SAFT), the project aims to encourage and enable people in urban areas to grow their own food. The project offers financial support to anyone who wishes to start their own urban agricultural project, as well as training courses, access to food markets and knowledge sharing platforms. The implementation sites of the farms varies from private house gardens, community gardens, areas in informal settlements, school gardens and institutional green areas (such as hospitals and factories).(Ref. 1,2) The Bangkok City Farm's role in promoting food self-reliance and food security grew further during the COVID-19. As a result of the pandemic, many people in Bangkok - especially from underprivileged communities lost their jobs and their livelihood and access to sufficient and health food was threatened. Thus, as part of the project, green areas on vacant sites of the city were also created to support the out-of-work people with enabling them for self cultivation of their food. (Ref.6) As of 2022, there are 165 farms in Bangkok created through the project. Given the success and importance of the project, the project was scaled up into a nation-wide initiative called ‘Thai City Farm’. 'Thai City Farm' expanded the network to five other cities in Thailand. (Ref. 1,2)
Odom garden: a pop-op greenspace demonstration
Odom Garden is a unique temporary pop-up public garden developed as a part of an ongoing real estate project (Ref 1). The garden was developed in 2020 to provide a green public space for people to connect with nature and with other citizens in a prime real-estate planned area for further construction in 2023 (Ref 1). Spread across 4000 sqm, the garden is developed by employing and upcycling the garden's native elements, such as large branches being converted into balancing paths and swing holders (Ref 3). The garden is a very popular green space in the city with Phnom Penh’s first dog park, a Japanese-inspired foot bath, and a central food and beverage area, as well as a children’s playground (Ref 2, 3). This green space has become a meeting place for families with opportunities for relaxation and recreation.
The park has been functioning since 2020 as a temporary site for the future Odom project. The area will be redeveloped to include a residential and commercial complex that includes a five-story layered park (Ref 1, 2). The project, when complete, is expected to increase the total green space area to 7000 sqm, i.e., 126% of the current Odom Garden. Of this, 80% of the green space will be accessible to the public. The Odom garden can thus be interpreted as a demonstration intervention, where the goal was to create s community-focused space and in which Phnom Penhers can experience the sense of community envisioned for the future completed project (Ref 1, 2). As of January of 2023, it has been announced that the Odom Garden is closing for the pre-construction of ODOM, with a "heartfelt: See You Soon" (Ref. 5).

The Living Land Farm
In 2005, local farmers in the sub-urban area of Luang Prabang combined their lands and founded The Living Land Farm, a rice farming community that runs an organic farm and an educational centre. The farm comprises of rice fields, vegetable gardens, homestay, and a restaurant. The aim of the farm is to preserve traditional rice-growing techniques, practice organic farming while also adopting new ways of grain selection and planting, and share rice farming knowledge with others. The products from the farm have been used in the local restaurant and are distributed to hotels and other restaurants in Luang Prabang city. The farm also serves as a training site for students of the Northern College of Agriculture and it offers ‘Rice Experience’ package for anyone who would like to learn about rice growing and the local Laos culture. The homestay and restaurant are run by local people of the village nearby and they are open to the public. The farm supports various community projects, such as village improvement and teaching English for local children. (Ref. 1,2,3)
JIWA Community Garden
The Project 'JIWA Community Garden' is a place to gather, garden, and learn and is located in Canggu, closer to Denpasar City in Bali (1,2,3). The project was founded in 2020 by three friends (citizens) and was developed on about 4500m2 of previously unused land (1,2,3). Jiwa Community Garden has set an example of how unused land can be turned into a fully functional composting facility, productive organic gardens, and a learning center for Permaculture gardening practices, all under one roof (1,2,3). It also welcomes all workawayer/volunteers and other local groups and expats to participate and contribute to activities for community engagement and learning (1,2,3). This project has created a positive impact, and still further plans to develop sub-projects like Permaculture gardening schools and a co-working space cafe open to the public (2,4).
SM Sky Garden
The green roof development forms a 400-meter-long floating green ribbon above the SM North EDSA mall in Quezon City, Philippines. [3] It boasts a 15000m2 area filled with 55 species of native trees, bushes, and flowers that thrive in the local climate, and it relies on stored rainwater runoff to sustain its plant life. Visitors can access the mall via entrances located within the garden's openings and tunnels leading to shops and cafes nestled beneath the botanical landscape. A meandering pathway guides visitors through the space, which features various entertainment options. The garden provides a unique and innovative space for mall-goers and city dwellers to relax and interact with nature. [1,2]
