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).

IKEA's biodiverse extensive rooftop garden
IKEA opened its doors in Budapest in 1990. This was the very first store in Hungary. Twelve years later, the store announced that it would install a green roof. The main purpose of the green roof was to compensate the locals for the loss of green space. The green roof was intended to create a biologically active surface that fits in aesthetically into the suburban landscape and provide a home for animals such as pollinators. The green roof, built in 2002, was covered with a Sedum carpet. In 2014, when the original Sedum vegetation died out, the green roof was completely removed. Then, during the autumn 2014 planting, four types of Sedum shoots were seeded. This was followed in the spring of 2015 by the seeding of herbaceous dicots seed mixes, which contained seeds of roughly 50 plant species. The vegetation is regularly monitored by ecologists: in 2021, more than 160 different taxa were recorded, including spontaneously occurring species. The green roof is closed, not accessible to the public, however tours are occasionally organized for professionals [3] [6] [8] [9] [10] [11].
Green Roof of Banyuwangi International Airport
Banyuwangi International Airport in East Java is the first green airport in Indonesia and was recognized with an award from the Aga Khan Award for Architecture (AKAA) in 2021-22, the world's oldest and most prestigious architecture awards (1,2,3,4). This project was designed and implemented by Architect Andra Matin in 2018 as a corporate social responsibility project for the Banyuwangi Regional Government, Java, Indonesia (1,2,4). The project building was extensively inspired by the houses of the local Osing tribe (1,2). The project aimed to embody a highly efficient passive design, with its remarking green roof feature of a total area of 4765m2 that is planted with grass and routinely maintained (1,2,3,5,6). The green roofs act like a sponge for heat, light and water and conserve energy by maintaining a constant temperature inside the building, and as a result, the airport does not require air conditioning in the main area (5). The green roof of the airport improves air quality as it captures airborne pollutants and atmospheric deposition, and the plants on green roofs also filter noxious gases (5). The eco-friendly airport terminal construction utilizes 'Fast Flow Siphonic System', especially for conventional roof drainage (5). The regional government declared a 10 km radius 'No Development Zone' around the project, protecting the existing paddy fields and villages, which is an exceptional move given the general tendency to exploit land around airports commercially (1,2). The current airport site caters to around 300,000 passengers annually and allows for future expansion to accommodate up to 3 million passengers without encroaching on the No Development Zone (2).
RISE Indonesia Project
Revitalizing Informal Settlements and their Environments (RISE) is one of the pilot projects carried out in the Batua neighbourhood (1.9 km2 area) of Makassar City (119 km2 area), province of South Sulawesi in Indonesia, which was commenced in 2017 and concluded in 2022 (1,2,3). Batua neighbourhood (six settlements of around 1,600 people) was the first demonstration site for this project which was completed in 2019 (3,4,5). The main challenge was that many households who lived in informal settlements lacked access to centralized urban infrastructure and faced threats from climate change (3,4). The project was proposed to reduce the impact of climate change on marginalized communities in Makassar by providing localized, water-sensitive interventions that addressed issues related to sanitation and water management (1,2,3,4). The introduction of water-sensitive solutions enabled targeted communities to recycle wastewater and rainwater, restore natural waterways, improve water quality, and reduce vulnerability to flooding (3,4). The RISE program initiative integrated nature-based solutions like wetland restoration, bio-filtration gardens (the process of using beneficial bacteria to clean water on a molecular level to remove contaminants), stormwater harvesting, filtration paths and new sanitation structures to improve wastewater management and diversify water resources through community-driven development (1,2,3,4).
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]
Sumatra Merang Peatland Project
Indonesia’s peatlands are among the most vulnerable ecosystems on Earth and also have significant potential as carbon sinks (1,2). Fire risk in Sumatra's peatland areas is high due to canals that were dug for logging and plantation development (1,2). The Sumatra Merang Peatland Project was thus launched to restore the area as the massive forest fire in 2015 destroyed thousands of hectares of biodiverse tropical forest (1). This project includes restoring more than 22,900 hectares of peatland rainforest in the Merang region, located within Musi Banyuasin Province, South Sumatra in Indonesia (1,2,3). The project targets the Merang biodiversity corridor, one of the largest and deepest peat swamps in South Sumatra, which protects an area more than 3.5 times the size of Manhattan (New York City) (1,2,3). This project is a part of the Althelia Climate Fund and was implemented on the ground by Indonesian Companies named PT Global Alam Lestari (GAL) and Forest Carbon (1,2,3,4,5). The project aims and contributes to climate change mitigation and ecosystem resilience by peat rewetting and reforestation, protecting biodiversity and working with local communities to build and improve livelihoods (1,3).
The first stage of the project is considered completed and is considered to achieve positive impacts already, but it still aims to upscale certain activities until 2025 (3,4,5). The total lifetime of the project extends to 2062 (4).

Pollution Mitigation at the Altynalmas Goldmines
The Sustainable Kazakhstan Research Institute (SKRI) at Narxoz University has developed "phytocapture," an innovative solution to deal with airborne dust. A phytocapture barrier is a chain of green spaces around a plant or mine, precisely calculated in height and width, to capture dust and organic compounds from production. This solution can capture 40% of particulate matter, including fine particulate matter, which otherwise settle in people's lungs, causing pulmonary and cardiovascular diseases. (1,6) To demonstrate the solution's applicability, SKRI proposed a phytobarrier project to AK Altynalmas JSC for the Aksu Goldmine. The Aksu field was founded in 1939, and soon the miners' settlement was formed around it. The formation of the tailings pond is closely connected with the production process, which began in 1951 and until now is produced by feeding through the pulp line the pulp from the gold concentration plant of the mill. The existing measures to reduce the negative impacts of tailing management facilities, such as irrigation of technological roads of the tailing management facility, as well as compliance with the above-ground stockpiles in the sections, do not fully solve this problem (5). To tackle this issue, the proposed phytocapture project utilized 3D computer modelling and digital technology to design a vegetation barrier near the tailing dump on both sides and resulted in the plantation of 1,400 seedlings of elm, silver sucker, and maple at a distance of 1.5 kilometers. The project was implemented at two production sites of the company in 2022 and is also being implemented in other projects. In 2022, the joint project was recognized by the United Nations Economic Commission for Europe (ECE) as a best practice (1,6).
Ayala Triangle Gardens
The 2-hectares public garden is located in Makati Central Business District of Metro Manila between the main arteries of Makati - Paseo de Roxas, Makati Avenue and Ayala Avenue - that form a triangle in the backyard of business towers. [2, 4]. The Garden was opened to the public in 2009 and showcases various trees and other plant species alongside numerous public artworks created by local artists [2]. The park provides habitat for hundreds of various trees of types, including rain trees, golden palms, fire trees, orange jasmines, and podocarpus. Two Filipino artists, Ovvian Castrillo-Hill and Ral Arrogante have created public art pieces scattered throughout the park [2,4]. The garden is also paved with verdant patches, providing a space for office workers to unwind and destress. In addition to serving as a place of recreation, the Ayala Triangle Gardens also hosts the yearly Festival of Lights as well as various music festivals. The Ayala Triangle Park is the first urban park to be built in Manila and the lush gardens are now considered a refuge for the residents of Makati [1,2,3].
Selangor Maritime Gateway and Klang River Rehabilitation
The rehabilitation of the Klang River or Selangor Maritime Gateway (SMG) is a project that was put into effect in 2018 by the Selangor State Government. The project aimed to transform the Klang River, considered the most polluted river in Malaysia, into a beautiful and clean river which can be a new source of economic growth in the state of Selangor, Malaysia. The river has been polluted with trash, plastic bottles, and sewage, which harmed the vegetation and the aquatic ecosystem (1). The project proved to be highly complex as it included rehabilitation of the river through several green solutions such as the creation of a community park, the conservation of various species of mangroves, and the implementation of riverfront greens as a measure of slope protection. The intervention is set to be developed on an area of 56 Km along the Klang River corridor. It is expected to promote and support the integrated management of river basins with particular emphasis on ensuring that biodiversity and wetland conservation and community considerations are incorporated into river basin management that includes the development of eco-city (3,5,6). Furthermore, the project intends to conduct an awareness campaign about river cleaning and rehabilitation activities to educate the public on the importance of rivers and the environment in our lives while consequently highlighting the critical state of pollution faced by the River (1).
