Danang, a prosperous port city in Central Vietnam, is home to a population of 1.2 million inhabitants. Throughout the years, the city went through several boats of urbanization, which allowed its economy to thrive but its environment to be negatively impacted. The city's green areas were reduced, leading to socioeconomic and environmental impacts, including loss of landscape and more energy consumption. (4) Furthermore, the city became vulnerable to natural disasters, which caused destruction and uprooting of trees and vegetation and aggravated soil erosion. (3,4)
To counteract many of these issues, the municipality of Danang initiated several greening activities that included the creation of parks, the greening of street alleys, and the greening of schoolyards as a supporting mechanism for one of Vietnam's nationwide programmes "Plant 1 billion trees in the 2021 - 2025" (5). Recently, the municipality planted 900 Than Mat trees (one of the typical flowering plants of Son Tra Peninsula and scientifically known as Millettia nigrescens Gagnep) along the route from Green Lake to Bai Bac, in the Tho Quang ward, in February 2023. The activity also aims to have an educational role as tree protection is highlighted and build a clean and green city environment (6).
So far, as of February 2023, as part of the 1 billion tree programme, 15,000 trees have been planted in Danang. (2)

Bangladesh is a country prone to floods and waterlogging, which results in two-thirds of this nation's land being transformed into wetlands each year. As such, much land becomes unavailable and the restricted access to it causes food insecurity as well as severe environmental pressure on the flora, fauna and ecosystems. The impact is even more serious as agriculture is one of the most important contributors to Bangladesh's GDP (1).
To respond to most of the climate challenges and food insecurities, in 2007 the International Union for Conservation of Nature (IUCN) and the humanitarian agency Care International, alongside other partners (including the Bangladeshi government), launched floating gardening (artificial islands, that simply rise and fall with the swelling waters) pilot project in the peri-urban area of the Gopalganj and other close by districts (1,2).
Floating gardens known locally as Baira are an old practice of crop cultivation in the wetlands of Bangladesh, the previous agricultural land, which got destroyed by the floods. The practice consists of piling together a number of dense layers of aquatic weeds like water hyacinth, duckweed, or paddy stubs and letting them decay. Afterwards, they're combined with silt and cow dung and inserted with plant/vegetable seeds left to flourish. On these beds, farmers cultivate fruits and vegetables like turmeric and ginger as well as okra, bitter gourd, snake gourd, spinach, and brinjal. In addition to veggies, rice seedlings can occasionally be raised. As a result, floating gardens are available to everyone, affordable, dependable, and completely in harmony with nature. (2,3) Furthermore, this aquatic farming practice has been shown to be highly effective in tackling the consequences of climatic variability and climate change like prolonged water-logging (3). The intervention has benefited approx. 2,000 families in the district of Gopalganj and it has opened the route for further projects that supported the practice of floating gardens (4).

The 'Wat Hua Lamphong Rukkhaniwet' Park was developed by the we!park group, which is part of the ‘Green Bangkok 2030’ project network, aiming to increase the amount of green space in Bangkok. It is a small pocket park in the busy business district of Bangkok, Thailand. The land was abandoned for many years before being donated to the city for public use. We!park applied participatory space development methodology to optimise and tailor the area to its soon-to-be users' needs. As part of this approach, the local community and all the potential users of the park were involved in the form of various surveys, interviews and workshops. Bringing in multiple ideas was a cornerstone of the project planning process - all to create an inclusive garden with elements from everyone in the neighbourhood community - a concept called 'garden next door'. The park has three main parts to accommodate different activities enabling relaxation, and physical activities, and providing space for educational and cultural events. (Ref. 1,2,3,4)

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).

The project “Enhancing climate resilience of Gorakhpur by buffering floods through climate-resilient peri-urban agriculture” is part of the Asian Cities Climate Change Resilience Network (ACCCRN) and financed by The Rockefeller Foundation. It was implemented by the Gorakhpur Environmental Action Group (GEAG) from June 2012 to May 2016 to demonstrate how ecosystem services generated by peri-urban agriculture can positively address the impacts of climate change in Gorakhpur, a city located in eastern Uttar Pradesh, India (Ref 1, 2). To be more specific, it was set out to “demonstrate flood risk mitigation through the preservation and improved management of open spaces by strengthening agriculture-based livelihoods in peri-urban areas” (Ref 1, 2). The main project outcomes were focused on conserving peri-urban agricultural land areas as they serve to climate-proof cities and build resilience, enhance the livelihood and food security of vulnerable groups in peri-urban areas, as well as establish sustainable and climate-resilient models (Ref 1). Activities like baseline surveys, field interventions, climate resilient extension systems, the adaptation of practices and research and advocacy were carried out to achieve the project outcomes (Ref 1). Additionally, the project has successfully improved the soil and water quality and developed special measures for waste management (Ref 1, 2, 3).

In Senegal, urban flooding in the rainy season causes major damage to public and private infrastructure, and poses considerable social, economic and health-related risks to the human population, in particular the poorest. Poor drainage systems mean that rainwater floods the whole neighbourhood, paralysing transport, and economic activities and posing health and safety risks due to stagnation and contamination (e.g. increase in water-borne diseases). To respond to such emergencies, in 2015 several stakeholders (Senegalese government, local authorities in Dakar and the local community) initiated a project that aimed to build resilience to flooding in informal settlements of Dakar. The project consisted of building resilience to floods by focusing on 3 fields: 1) infrastructure (floodwater evacuation, solid waste management, urban gardening and greening); 2) policy (district flood contingency plans and national policy advice); and 3) capacity building (training and awareness building for beneficiaries and key stakeholders, with a special focus on empowering women). The project was concluded in 2017 however its benefits are still felt today by the inhabitants of Greater Dakar. (1,2,3)

"Siargao It Up" is the mangrove conservation programme in Del Carmen, Siargao Islands of the Philippines. The municipality of Del Carmen hosts the largest mangrove forest in the Philippines – consisting of 4,871 hectares as of 2018. This mangrove forest is the habitat of rare and endangered species of flora and fauna both in marine, wetland and terrestrial areas. This ecosystem helps maintain the island's ecological balance by providing rich breeding grounds for aquatic lives. Furthermore, the forest plays a key role in capturing and storing carbon and helps the Philippines to meet its goal of carbon emission reduction. In addition to creating habitats and storing carbon, the forest also protects the community from the inevitable effects of climate change disasters. Recently, in December 2021, it was able to protect the residents from the onslaught of Typhoon Odette. [1, 2, 3]

In order to promote Urban and Periurban Agriculture and Forestry (UPAF) as a municipal strategy to deal with negative climate change effects, Bobo-Dioulasso local authorities have identified, using a participatory approach, city greenways as experimentation sites for local climate solutions. The intervention consists in transforming vacant land belonging to the city into green corridors (greenways) through market gardens and forestry, retaining the benefits of urban agriculture. Urban agriculture, when planned and managed properly, can contribute to climate change mitigation efforts by lowering the ecological footprint associated with food production. At the same time, urban agriculture can enhance climate change adaptation efforts by increasing vegetation cover and reducing surface water run-off, while at the same time conserving biodiversity.

The Ras Mekonnen Urban Park is part of a larger intervention developed by ICLEI (an international NGO focused on the promotion of sustainable development) with the Addis Ababa municipality alongside the Shega river that crosses a nearby neighbourhood. The location of the park was initially used by locals as a dumping site affecting not only the quality of life of the inhabitants but also contributing to the environmental degradation of the area. As more and more people discarded their waste here, the small river running through the site, a tributary of the Shega River, became increasingly overgrown and inaccessible, resulting in a derelict, run-down space in an otherwise vibrant urban area. As such, action was needed, which eventually resulted in the rehabilitation of the river and the creation of the park, which now can be enjoyed by all the inhabitants of the Ras Makonnen neighbourhood.

Mauritania is one of the Sahelian countries most severely affected by the periods of drought occurring since 1968. The resulting desertification is exacerbated by human activities, which have compounded climatic factors, with direct consequences for an already precarious situation. Environmental degradation, responsible for the dangerous displacement of sand dunes in Mauritania, has wiped out homes, livestock and livelihoods throughout the desert country. In Nouakchott, Mauritania’s capital and biggest city, the coast are protected by a fragile wall of dunes at risk from natural erosion, sand mining, grazing of livestock on dune vegetation, and careless abuse of the landscape for leisure like dune racing. In this scenario, protecting the dunes is a priority, and the government is using World Bank financing to overcome the challenge. From a climate change perspective, the intervention addresses accelerating erosion that allows seawater to wash into the city, assaulting buildings, roads, fresh water supply and public space. From a biodiversity perspective, the intervention aims at sustaining the balance between the food for the livelihoods of the local population and the preservation of the rich coastal biodiversity.
