The frequent and severe floods that many cities in Lao PDR have been experiencing are causing a significant impact on the livelihood of local and vulnerable communities. To address the issues of flood and climate events, the Green Climate Fund has provided funding for the Lao DPR government to initiate the 'Build Resilience of Urban Populations with Ecosystem-Based Solutions in Lao DPR' project. The Ministry of Natural Resource and Environment of Lao, in collaboration with other related departments, universities, and provincial governments, is leading this project. The funding was approved in 2019, and the project is set to conclude by 2025. The project consists of four sub-projects, which will be implemented in four cities, including Paksan, Vientiane, Savannakhet, and Pakse. One of the sub-projects involves rehabilitating the Nong Peung wetland in Paksan city, which currently has no management plan and is negatively impacted by human activities and has been degraded in certain aspects. Natural vegetation has been lost in parts of the wetland, invasive alien plants are encroaching, and the natural water flow has been disrupted in places. The objective of this project is to develop a comprehensive management plan for Nong Peung wetland and implement various nature-based solutions to improve the ecosystem. This will involve removing invasive alien plant species, eliminating human-made barriers that obstruct natural flow, and planting appropriate native species. Currently, the project is in the planning stage with relevant stakeholders to determine the physical implementation site. (Ref.1,2,3)

Located in downtown Bandung, with an area of 3.8 hectares, Babakan Siliwangi (more commonly known as Baksil) has been declared The World City Forest on September 27, 2011, by the United Nations Environment Programme (UNEP). It is part of the green belt of Bandung and is a place of recreation for residents and features a canopied walking path. Declaring the forest as part of the urban green belt of the city has not been an easy task for the management team of Baksil as in 2011, there was a plan to build privately-owned multistories building at the site, which would greatly reduce the environmental quality of the area. In response to this challenge, the team initiated a series of awareness actions as well as a planting campaign to raise the profile of the forest, as well as to address several environmental challenges such as emissions reduction, noise pollution, soil degradation, and fauna and flora conservation. The intervention proved to be very successful as it established the Baksil forest as a new public space that enabled people to get to know and better appreciate their city forest. Several communities have been holding events in this area to activate the idle space, while inviting more people to interact with the forest, making it to be invaluable for the local community and the city of Bandung.

The extensive Rain Garden Project underneath the Begumpet flyover was carried out in Hyderabad City of Telangana State in India as a beautification project, creating a wetland system banked by lush vegetation (1,2, 4). The Hyderabad Metropolitan Development Authority (HMDA) developed this project to restore, conserve and regenerate the environment of stormwater drains (locally named as open 'Nalas') (1,2,3,6). This project is located at the intersection of Kukatpally Nala and Yousufguda Nala and stretches over 2 hectares and runs for 400 meters (1,2). The project was created for a more natural flow of stormwater to allow it to soak into the ground as well as reduce mosquito breeding on Nala (1,2). It was completed in 2018, creating a positive impact, through which the Hyderabad Metropolitan Development Authority (HMDA) further decided to develop more such projects in other parts of the city (4). Hyderabad City was also awarded for this project under the green and clean city category - Smart Cities India (SCI) Awards (5).

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).

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).

Angkor Botanical Garden is Cambodia's first botanical garden, located in the city of Siem Reap. It is a popular tourist attraction for visitors from around the world who visit the famous Angkor Wat Buddhist temple. The garden was developed by APSARA National Authority with multiple benefits, including preventing forest land encroachment, conservation of natural resources, development of tourism, conservation of the Angkor archaeological site, environmental education, and preservation of rare and endemic plants (Ref 1, 4). Moreover, the garden has been also well-received as a place for relaxation and recreation. (Ref 1 and 2)
The garden was initially a 2-hectare spice garden, which has been transformed into a 15-hectare garden with an automatic irrigation system linked to the Siem Reap River and landscaped with hills, ponds, canals, and waterfalls (Ref 1). The garden has more than 500 different species of plants and is developed to showcase the relationship between plants and animals (Ref 4). In the future, the garden is planned to be expanded into an area of 130 hectares. (Ref 2)

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).

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).

The ‘City of 1,000 Tanks’ project offers a holistic solution to the problems of floods, water scarcity and pollution in Chennai (Ref. 1). The project's primary objective is to develop a "Water Balance Model" for the city, which involves collecting rainwater, treating wastewater and runoff pollution with decentralized nature-based solutions, as well as prevent climate-change-induced droughts and saline intrusion due to sea-level rise (Ref. 1, 2). This is achieved through developing various nature-based water management solutions and improving the recharge capacity of traditional temple tanks (Ref 1).
The project began in 2018, following the call for action event of the "Water as Leverage for Resilient Cities Asia" (a bilateral program spanning several Asian countries). The Water Balance Model is developed as a strategy with an incremental implementation process (Ref 1, 2). The project started with pilot projects and then progressed to flagship projects before full city-wide implementation (Ref. 3).

In 2021, the local municipal government of Navi Mumbai City and a local NGO converted a neglected urban space used as a dump yard in Nisarg Udyan into a healthy and dense forest (Ref 1,2). The aim of the project was to improve biodiversity and complement the local ecosystem, choosing specifically native species from the local area for plantation (Ref 3). By applying the Miyawaki forest technique, the project was able to transform the wasteland into a 3-acre mini-forest quickly. A civic officer on behalf of the Navi Mumbai Municipal Corporation (NMMC) drove the re-forestation project jointly with the support of Green Yatra, a local NGO, and corporate social responsibility (CSR) funding support from Sony Music Entertainment (Ref. 1, 3).
