Kota Malang is a city for which urbanization coupled with climate change caused an increase in its vulnerability to the urban heat island effect. One of the solutions found to address this issue has been urban farming which has been recognised and acknowledged as a top strategy to improve cities' resilience associated with social and economic co-benefit. Nevertheless, urban farming inventory in Indonesia is still limited (1). Currently, there are 21 urban farming plots throughout Kota Malang, with 210 active urban farmers involved. The city has adopted this trend since 2013 as part of an initiative called Kawasan Rumah Pangan Lestari (Sustainable Food House Region) and the Initiative of Urban Farming Malang. Alongside the local government, the major stakeholder groups are the Department of Agriculture and Food Security of Malang, Family Welfare Empowerment (PKK) Malang and Bank Indonesia (BI) (Corporate Social Responsibility (CSR) program, which supports the local government in construction and development in Malang.
In Kota Malang, urban farming comprises five types of urban farming: nursery, allotment, residential, institutional and rooftop farming based on its characteristics (1). A recent report showed that urban farming could contribute to community resilience for feeding potential and nutrient sufficiency, especially for targeted populations with the highest risk during emergencies such as the COVID-19 pandemic. In the case of Kota Malang, the cultivation of specific vegetables could feed up to 50,000 inhabitants aged 60-64 years old (1, 2).

In 2005, a constructed wetland was established in Barangay Villareal, Bayawan City in order to improve a peri-urban settlement and promote domestic wastewater treatment with reed beds. The wetland covers an area of 2680 square metres and comprises two reed beds, with the first bed utilizing perforated pipes beneath a sand and gravel substrate for vertical flow filtering, and the second bed utilizing horizontal flow for biological filtering. The roots of the Phragmites karka reeds, which are used in the system, act as a natural filter, removing microorganisms and pollutants. The treated effluent is reused for various purposes, such as watering plants, firefighting, and irrigating ornamental plants and agricultural crops. The overarching objective of the initiative is to safeguard coastal waters from pollution caused by domestic wastewater and enhance residents' quality of life by providing safe sanitation and wastewater treatment facilities. Furthermore, the initiative seeks to showcase the effectiveness of constructed wetlands, encourage the use of locally available reeds for wastewater treatment, and conserve water and nutrients by reusing treated wastewater.

Since 2012, the Municipality of Ipoh continued the revitalization and rehabilitation of the D.R. Seenivasagam Recreational Park (TDRS) under the Malaysian National Urbanisation Policy, which suggests that for every 1,000 inhabitants, there should be public green open spaces of 2 ha. Through this intervention, the Ipoh municipality tried to address several sustainability challenges, which are usually a result of the lack of green open spaces. Some of the challenges addressed were the urban heat island effect, soil erosion resulting from improper drainage, and noise pollution. Ultimately, the municipality aimed to provide a convenient setting for a variety of leisure and recreational activities in addition to enhancing the civic values of the community. The intervention consisted of several tree-planting actions organized by the Ipoh Council in collaboration with the Perak Government (a Malaysian state that has its capital in Ipoh).
D.R. Seenivasagam Recreational Park was built in the 1950s and is one of the largest urban parks in Ipoh. It has become a favourite among locals as well as an example of good practice for integrating green open spaces in addressing sustainability challenges over the years. Located in the vicinity of the Kinta River, during the early days of its opening, it was a mini botanical garden which eventually transitioned to a full-scale park, one of not too many in Ipoh. The park also includes a lake with wooden bridges that contributes to the diversity and habitat of the place. The DR Park, as it is known to the locals, has entertained many families for more than 25 years, starting as a mini-theme park during its formative years, much to the delight of many children. To date, the park has remained a popular spot with abundant greenery and attractions, an oasis within Ipoh’s city life. (1,2,3,4)

Uuliin Nuur (Mountain Lake or Green Lake) is a community park located in the ger district area known as Denjin Myanga of Ulaanbaatar city. The Ger district is a term commonly used in Mongolia to refer to a type of settlement located on the outskirts of the country's capital city and characterized by traditional Mongolian gers, or yurts. The area was once a quarry for the city’s construction during the socialist regime (from 1946 to the late 1960s) and was turned into a dumping ground after its closure. In 2009, a private citizen, Ulziitogtokh Sodnomsenge, gained approval to develop Uuliin Nuur. He cleaned up the area and used his savings to turn the former dumpsite into a green garden in the middle of ger areas to create a healthy, green, public space, especially for children living in the area. He opened an ice rink in the winter of 2012 and officially opened the Uuliin Nuur park in May 2014. From 2013 to 2019, approximately 1000 trees and shrubs were planted in this park during the spring and autumn. The trees were planted by the founder of the project by locals and foreign visitors as memorial trees. Over the years, the park was equipped with various community facilities to support social interaction and educational purposes. Uuliin Nuur is one of the few public places launched and developed by an individual. It showcases how abandoned places can be transformed into valuable places and how the local community's attitudes and awareness can change. (Ref. 1, 3, 4)

Doh Eain, which means “Our Home” in the Burmese language, is a community-centred design firm that converts trash alleys in Yangon into gardens, composting stations, street markets, playgrounds, and art galleries, where community members can make memories and positive change.
As Yangon has one of the lowest public space-per-person ratios in South East Asia, Doh Eain saw a role for a social enterprise to preserve and improve heritage and urban landscapes directly with the people and communities who inhabit them. Doh Eain’s vision is to collectively make cities more vibrant, inclusive and sustainable places to live, work, and enjoy by maintaining the city's unique characteristics and creating an urban environment that enables people and society to thrive. Their mission is to preserve heritage, improve public spaces, and organise activities that connect people with places, employing a user-centred and participatory approach. In doing this, they aim to inspire and enable people to participate in reshaping their city while retaining cultural heritage (1).
The Yangon's alley gardens project started when a group of young, local and expatriate residents in Yangon decided to set up a small permaculture garden, however, they could not find a suitable plot of land for it (2). As a consequence they had to change the focus and transplant green pots filled with vegetation and vegetables into the back alleys. The implementer used an innovative technique by using bokashi composting of food waste, with around 80 households signing up to take part in the initiative. (5)
The initiative was quite successful as it helped break the cycle of throwing trash out the window into alleyways and built several elevated garden beds. (6)

Penang is a state located in north-western Peninsular Malaysia with an area of 1,049 km2. It comprises two local authorities, Penang Island and the mainland. The former is further divided into five administrative districts which are further divided into mukims (sub-districts). Two urban mukims located on the island – George Town and Bayan Lepas – are the focus of the proposed nature-based solutions (NBS) climate adaptation programme. The programme was launched in 2022 by UN-Habitat in collaboration with the Ministry of Environment and Water (KASA) of Malaysia, Penang Island City Council (Majlis Bandaraya Pulau Pinang - MBPP), Department of Irrigation and Drainage (Jabatan Pengairan Dan Saliran - JPS) and Think City (a wholly-owned subsidiary of Khazanah Nasional Berhad (the sovereign wealth fund of the Government of Malaysia)). (Ref 1)

The implementation of the project responds to several challenges posed by climate change including heatwaves and flooding (Ref 4). The main goal of the programme is to enhance urban resilience and reduce human and ecosystem health vulnerability to climate change impacts and extreme weather events by implementing nature-based solutions (NBS) such as tree-lined streets, pocket parks, green parking spaces, green facades and rooftops, urban agriculture and blue-green corridors to reduce surface temperatures and stormwater runoff, as well as to increase social resilience and build institutional capacity (Ref 1, 3).

A new nature sanctuary was unveiled at the Kingfisher Wetlands, Gardens by the Bay, in Singapore in 2021. Before the sanctuary was created, the original site was a popular bird-watching spot for the birding community and nature photographers. However, it was isolated and "often missed by the general public". The new Kingfisher Wetlands was thus developed with the aim of enhancing and enriching the Gardens, as well as providing new nature areas for visitors to explore. The place is a new hotspot for the flourishing diversity of exotic flora and fauna. Furthermore, the project helps in mitigating climate change through mangrove plantations. Over 200 native true mangrove trees and mangrove associates have been planted, contributing to sustainability by storing “blue” carbon. Additionally, the project actively supports research into blue carbon science. This contributes to the country's effort to transform Singapore into a City in Nature by weaving nature more intensively into the urban fabric. [1, 4]

The city of Bishkek once had the status of one of the greenest and most pleasant cities in the Soviet Union. The situation has deteriorated from year to year, so much so that in 2009 Bishkek was ranked sixteenth in the list of the thirty dirtiest cities in the world in a study published by The Blacksmith Institute, an American NGO which discloses each year an urban environment assessment report. This is why it seems urgent to us to react and work to protect, renovate and develop the green spaces of Bishkek. The proposed project aims to protect the unique forest of Bishkek called Karagachevaïa Rocha (“grove of elms”) and to redevelop it to make it an environmental education centre. This center, which would be the first of its kind in Kyrgyzstan, would include in the same place an arboretum, a leisure area as well as an animal park in which various rare or endangered species, present in Kyrgyzstan or in the countries of Central Asia, would be kept in semi-freedom. Karagachevaya Rocha has nearly 123 hectares in total, which is the largest green space in Bishkek and one of the oldest. This adds a symbolic character to the project. (3)

Peru has seen a sharp increase in major flooding, prolonged droughts and water scarcity of supplies in the dry season, negatively impacting agriculture, migration, conflict and economic growth in recent years. As 71% of the world's tropical glaciers are found in Peru these climatic changes affected the country profoundly leading to a decrease in the glacial surface and creating unstable lagoons also causing natural disasters such as alluvium landslides and deadly flash foods. Glacial melt is also disrupting water flow and quality, posing a threat to the flora and fauna that rely on freshwater environments. Unsustainable management of fragile glacier ecosystems is causing environmental degradation and biodiversity loss. To counteract many of these challenges and to safeguard the communities that are in peril, in 2011, the Government of Peru together with a number of stakeholders, initiated an intervention to sustainably manage more than 200 new lakes that affect directly populations in different cities in the Ancash, Cusco and Lima regions, Huaraz being one of the cities targeted. The project benefitted downstream communities and protected fragile high-altitude freshwater ecosystems. (1,2)

In 2019, the public initiative "Let's return the rivers to the city" campaign united public forces around the Podborenka river, which flows through the territory of Izhevsk along its entire length [1, 4, 5]. In an urbanised environment, the river was abandoned due to water pollution, poor treatment of stormwater, road and industrial runoff, soil erosion, and due to presence of landfills in the valleys [1, 4, 7]. Therefore, the project's primary goal is to increase the efficiency of urban resources and the creation of new scenarios for resource use on the example of the space of the riverbed of a small river [3]. The project implementation contributes to improving the ecological situation of the Podborenka River, its embankment zone and biodiversity [1, 9]. Also, the project implementers paid particular attention to the education of young people, the development of volunteer movements, and raising the level of the ecological culture of the population [1, 2, 6, 7].
