Ecological restoration in Rohingya refugee camps
The United Nations High Commissioner for Refugees (UNHCR) and its partners collaborated in 2018 to develop an ecosystem restoration project in the Rohingya Camps of Ukhiya, near Cox's Bazar. The main objective of this project was to mitigate the increased risk of landslides, slope instability, and flooding caused by flash floods and the vicinity of the Bakkhali River. The intervention included the planting of quickly growing native trees, shrubs, and grass species. Additionally, the project encompassed other measures such as vegetable cultivation on stream beds, biological soil stabilization methods, and plant-based wastewater treatments. To ensure the sustainability of the project, a network of future practitioners from the Bangladeshi and Rohingya communities was created. Moreover, environmental education and awareness activities were undertaken to complement the efforts of the project, with a particular focus on engaging young people from both the host and refugee communities to maximize its impact. The area where the project was implemented has been significantly affected by land and forest degradation over the last few decades, which has been exacerbated since the arrival of Rohingya refugees in 2017. Therefore, the project also involved other stakeholders such as the International Center for Conservation of Nature (IUCN), the Danish Refugee Council, the World Food Programme, the International Organization for Migration, and the Bangladesh government, each contributing in various capacities to achieve the project's objectives.

Vinh River Rehabilitation Project
Vinh is the biggest city in north-central Vietnam and is the hub for economic and cultural development in the region. As of 2018, the city has a population of approx. 500,000 inhabitants and is located on the Ca River delta, 160 miles (260 km) south of Hanoi. Flooding and poor environmental sanitation are major impediments to the development of Vinh City. The drainage system of the city is comprised of four catchment basins connected to Rao Dung, Ke Gai, Vinh and Lam Rivers. Among the four, the Vinh River is flowing through the central wards and communes of Vinh City and is one that becomes sensitive to severe flooding events frequently (2,3).
Recently (in 2021), with support from the World Bank, the government initiated a program, the Vinh City Priority Infrastructure and Urban Resilience Development Project (VPIUR), which is expected to bring a new look to the river, reduce the risk of flooding in urban areas and strengthen urban management capacity to adapt to climate change. This project has several sub components and one of them is a river rehabilitation and upgrade under the form of riverbank green, sanitation, and flood risk management (1, 3).
The implementation includes a comprehensive set of structural and non-structural interventions, including flood control systems and nature-based solutions, wastewater collection and treatment infrastructure, and key transport links. The project aims to transform it into green public spaces which are to be constructed under the project. The project also aims to invest in developing green public spaces along the Vinh riverbank and a new regulation lake. (3)

Constructed wetland
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.

Ulaanbaatar Urban Forest
The "Urban Forest" project focused on the establishment of the Mongolian-Korean Friendship Forest on a 40-hectare land in Dambadarjaa, Sukhbaatar district of the capital city, Ulaanbaatar. Previously known as the Forest Research and Development Center Arboretum Park, this area has a river running through it. The project, with a total cost of over 8 million EUR, was designed specifically to reduce air pollution in the capital, to create a healthy eco-environment for Ulaanbaatar residents to spend their leisure time and to raise awareness of the importance of forests and the benefits of trees in Mongolia. In total, 55,000 trees and shrubs of 36 different species were planted so far and the park boasts five different types of coniferous trees that thrive in Mongolia, including larch, pine, abies, cedar, and spruce, as well as deciduous trees such as birch, aspen, willow, lilac, and maple. The Urban Forest park also includes several facilities, such as a visitor information center, a playground, sport facilities, a natural arboretum and a ground fountain. The park will be operational and accessible to the public in 2023. The project was implemented between 2017 and 2022, as the second phase of the Korea-Mongolia Greenbelt Reforestation Initiative jointly developed by the Mongolian Ministry of Environment and Tourism (MET) and the Korea Forest Service (KFS). The Green Belt initiative was created with the overall aims to mitigate desertification, combat climate change, and reduce yellow dust and sandstorms in Mongolia.

Buku Jalanan Chow Kit Urban Farm
To address the increasing pressure on urban green spaces, Buku Jalanan Chow Kit, an NGO in Kuala Lumpur initiated a green project where the local community could thrive, learn about the benefits of nature and use their ethnobotanical heritage. The project provided a way to enrich biodiversity and enhance the sustainability and resilience of the local communities (1).
Kuala Lumpur, the Capital and the largest city in Malaysia is home to 1.8 mils. people. Due to its growing population, the city experiences a steep decrease in existing green spaces, increasing urban heat effects and air pollution (4). Furthermore, privatizing public spaces led to a loss in biodiversity throughout the city and severely affected the environment. The current project will focus on creating ~2500 sq ft (~232.2576 sq m) rooftop urban farm, biodiversity garden and playground on an existing building. This space will be a habitat for urban wildlife, as well as a space for food production and recreation (1). The project benefits from funding through the UN's GEF Small Grants Programme and aims to provide a community capacity-building space to engage and host activities to empower the Chow Kit community.

National Garden Park
The National Garden Park is the largest park in Ulaanbaatar and the only park of its kind in the capital city of Mongolia, offering multiple environmental services, recreational and commercial functions. Currently, the park extends to 183 hectares, covering 23% of the total green construction in the city, and stretches from the northeastern part of the Marshall Bridge to the Uliastai Bridge in the Bayanzurkh district. In the long term, the park is planned to be extended to have a total area of 973 and to have 1.200.000 trees planted within the “One Million to One Billion” afforestation program. The park offers a range of recreational facilities and services for citizens, including bicycle and pedestrian areas, specialized sports areas and children's playgrounds. It also houses trade and service organizations. As a result, the park has become a popular recreational area for the citizens of the capital and is the most visited urban park in Ulaanbaatar. During the summer, it attracts an estimated 12-15 thousand visitors a day, and during the winter, it sees 6-9 thousand visitors a day. The National Garden park was officially established in 2009 with the aim of protecting the Tuul River Basin's drinking water source, reducing air pollution, and increasing green space to create a healthy eco-environment and providing recreational opportunities for the public. In 2016, the National Garden Park was designated as a local property budgetary enterprise with defined primary functions, management structure, control, and rights under the administration of the Assembly of Citizens' Representatives. The park currently employs 113 staff members (as of 2021). (Ref. 1. and 4)
Thane Creek Flamingo Sanctuary: management plan
The northern part of Thane Creek in Navi Mumbai was declared a 'Protected Area' in 2015 by the Maharashtra Government (1,2,4). As the Central Asian Migratory Flyway (CAMF) ecosystem, it is occupied by a large number of wading birds, especially Lesser Flamingos and Greater Flamingos (1,2). Recently, a Management Plan has been proposed to guide the sustainable management of the 'Thane Creek Flamingo Sanctuary (TCFS)' (1).
The Management Plan (2020-2030), proposed by the Mumbai Mangrove Conservation Unit (MMCU) proposed implementation plans for the conservation of Flamingo species, mangrove management, eco-tourism, education and awareness raising, as well as participatory decision-making (1).
Thane Creek harbours rich biodiversity and spreads over an area of 1690ha (896ha of mangroves and 794ha of adjacent creek water body) (1,2,3). Also, it is located right amidst a mega-city, being crucial to conserving this unique natural environment with its eclectic mix of mangroves, mudflats and threatened bird species (1,2).

Building Coastal City Resilience in Pekalongan
As an archipelagic state, Indonesia consists of 18,000 islands and 18,000 km of coastline, which is inhabited by more than 60% of the Indonesian population. Its geographical position exposes the island country to several climate change challenges, ranging from an increase in high temperature to a sea level rise and severe floods. One of the cities affected by flash floods, flooding, and landslides is Pekalongan City, crossed by 7 rivers and home to approx. 300,000 people. Inundations can reach 50-100 cm in many communities, causing distress, evacuations, and severe damage to infrastructure and food security as well as loss of income for the inhabitants that work in the fisheries sector, in the Batik industry (the process of traditionally dyeing fabric, performed on cotton and silk using a resist technique) or in paddy rice farming. (1)
Responding to the climate risks became of utter importance to the municipality of Pekalongan City. To help the Municipal Government of Pekalongan City to overcome the problem caused by climate change, Kemitraan (Partnership for Governance Reform in Indonesia), an implementing and advocacy NGO developed the project on Safekeeping-Surviving-Sustaining towards Resilience, a 3S Approach. The aim was to Build Coastal City Resilience to Climate Change Impacts and Natural Disasters in Pekalongan City, Central Java Province. This was approved on 29 October 2020 and is currently entering its implementation phase. The project will focus on building resilience to climate change impacts with interventions of hard and soft nature. More precisely, the project aims to build capacity and resilience through training, mangrove ecosystem restoration and enhancement of coastal protection, and development of a Local Climate Adaptation Action Plan and implementation of climate-smart actions (1,2). The project aims to reach these goals by employing a collaborative and participatory approach that is locally driven and involves those most at risk. The program is expected to end in April 2023 (1).

Community Mangrove Biodiversity Conservation in Penang
In order to prevent the damage to mangrove forests that occurred over the last few decades or more, a project was started in the Penang region aiming to raise public awareness regarding the importance of mangroves for their continued conservation and protection through active community participation (community resilience) (1). The project closely relates to the GEF Focal Area on Biodiversity Conservation operational programme (OP) 2 on Coastal, Marine and Fresh Water Ecosystems and is led by the Penang Inshore Fisherman Welfare Association (PIFWA). The project aimed to regenerate mangrove forests by planting up to 11,000 saplings in order to rehabilitate the once degraded mangroves as they are able to ultimately improve the wetland ecosystem and its biodiversity and thus sustain the livelihood of fisher communities (1).
Mangrove forests are an important part of the Malaysian coastline. Besides their contributions to the biodiversity of the Malaysian coast, mangroves also help greatly with protecting the coastal strip from erosion and providing a means of living for the communities located close to the forests. Stabilising the shoreline and reducing soil erosion, mangroves are also home to myriad species of plants and animals, they provide timber and non-timber forest products, and they support fisheries (1,2). Due to their importance, their disappearance is greatly noticed. From 2000, within a period of 15 years, 25,500 hectares of mangrove forests disappeared, mostly due to industrial-scale logging, clearance for shrimp farming, tourism or firewood (5).

Penang Nature-based Climate Adaptation
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).
