The International Institute of Rural Reconstruction (IIRR) Myanmar and its local collaborative organizations developed a community garden at Inn Dein village to ensure access to diverse and safe food amidst the current internal crisis in Myanmar. The community garden is a part of the wider research project “Climate-smart villages as platforms for resilience building, women empowerment, equity, and sustainable food systems”, funded by the International Development Research Centre (IDRC). The expected outcomes are to benefit over 4,200 internally displaced persons (IDP) (due to COVID-19 and internal conflict) in Inn Dein and the Yangon Monastery Camp in Nyaungshwe. The community garden was established in the close vicinity of the Internally Displaced People (IDP) camp. The garden area is about 1.5 acres and rented for three seasons from the owner. Saplings were supplied for agroforestry purposes and a community support fund has also been provided for income generation and livelihood activities. Sprinkler irrigation has been installed to cover the whole land area, and 20 types of crops, including several legumes crops and vegetables such as mustard, radish, carrot, coriander, okras, eggplant and pumpkin are being cultivated. This project is particularly important in the current situation "[because of the lack of opportunities to direct support to IDP camps and the risky situation in food supplies, access to food and nutrition for IDPs is critically important." This project benefits both addressing food insecurity and increasing green space in the neighbourhood of the IDP camps. (Ref 1).

In April 2021, the Kochi City Corporation in collaboration with the World Resources Institute (WRI) and ICLEI South Asia inaugurated the Subhash Bose Park after a thorough renovation. The project was part of the overarching project "INTERACT-Bio" by ICLEI South Asia and the KAWAKI initiative by the WRI (part of the Cities4Forests movement in Kochi). The initiative was launched to demonstrate the application of Nature-Based Solutions (NBS) for climate mitigation in Kochi. The project aims to develop urban grooves similar to the traditional grooves that once existed in Kerala. Additionally, with this project, ICLEI South Asia aimed to address the problems of climate change through mainstreaming biodiversity objectives across the city. The park plays as a major carbon sink at the heart of the city that is home to over 300 species of native trees and many more species of native plants. Furthermore, the Kochi City Corporation is focused on increasing native biodiversity and communicating the importance of this biodiversity to residents in order to ensure long term conservation efforts. This was a key motivator for the city in the conceptualization of the garden which not only improves the native biodiversity of the city but also serves as a demonstration site for nature education. The park also includes a newly built pollinator garden that has augmented the pollinator base in the city. [1, 4, 7, 10]

Droughts are one of the most serious threats to water availability, food security, and local livelihoods in the semi-arid areas of Tanzania. Drought condition is coupled with a rainfall deficit and poor rainfall distribution. In Tanzania, drought conditions are observed more frequently in the country's northern and central portions (Arusha, Manyara, Shinyanga, Simiyu, and Dodoma). This consideration was paramount when in 2019, the Municipality of Dodoma, alongside ICLEI - Local Governments for Sustainability, erected a new garden positioned in a square in the centre of the city. Nyerere Square in Dodoma used to be an open, concrete space with the statue of Julius Kambarage Nyerere the only attraction apart from the informal traders scattered along the main walkway. Nyerere is the former prime minister and president of Tanganyika, as Tanzania was known before, and subsequently president of Tanzania. It would prove challenging to sustain such an initiative in this drought-prone city. To ensure the park outlived the project, the team installed a greywater system to irrigate the new garden and ensure there was always sufficient water to help the plants flourish. (1,2,3)

South Africa is struggling to provide services to the millions of poor people migrating to the major centres and living in informal settlements (shanty towns), built on land that was formerly used for agriculture or pasturage. Vegetation is sparse and the open spaces between the houses are generally of beaten earth. These areas face persistent challenges that undermine health and everyday well-being and increased disaster risk due to their poor design and lack of green infrastructure. Moreover, informal settlements are very vulnerable to flooding events, which affect the quality of life of the people living in them. Such a case is Diepsloot, a settlement in Johannesburg, where a team of researchers implemented a sustainable urban drainage system with the purpose of alleviating poor water infrastructure and addressing issues related to land erosion and environmental degradation. This research has been benefiting from the support of the local population through adaptive co-management and joint implementation of the intervention. (1,2)

Rising temperatures, longer dry spells, more intense heavy rainfall and sea-level rise, make Tanzania the 26th most vulnerable country to climate risks. Dodoma, the country's capital, is a city with a rapid rate of urbanisation and uneven population growth. The near-central business district, peri-urban and urban parts of the city, have grown very fast as a result of intensified urban planning and surveying of land. A way of addressing these stringent issues was developed by ICLEI, an international NGO, which focused on the relationship between nature and urban planning and initiated an intervention in the form of a community farm in Dodoma.
This project aims to develop, 15 km from Dodoma's city centre, a community farm that will focus on producing enough food for the inhabitants of the city and its surroundings. The farm is the first in a project that will try to establish foodways. Foodways include customs of food production, preservation, preparation, presentation, gathering, marketing (both buying and selling), uses of food products other than for eating and food folklore.”The project dates back to the beginning of 2020, and it is still ongoing.

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.

The construction of "the biggest vertical garden in Uruguay" was completed in 2014 (Ref. 1). The vertical garden has an area of 300m2 and contains over 6,000 plants, of which most are endemic, comprising 35 species and 10 different families (Ref. 2). In addition to being aesthetically pleasing, the garden is intended to reduce temperature, produce oxygen and offset greenhouse gas emissions. It is thought to "contribute...to the filtration of approximately 165 tons of gases per year and [be] capable of producing the necessary oxygen for 255 people, in addition to trapping 130 kilos of dust" (Refs. 2 & 3).

A rain garden has been implemented at the Fazenda Lagoa do Nado Municipal Park in Belo Horizonte. The rain garden has been created as "a solution that contributes to the runoff of rainwater, allowing the water to be filtered through vegetation and infiltrate into the soil", with this type of solution being recognised as a method which "recharge[s] the water table, increases biodiversity, improves the local microclimate and air quality" (Ref. 1). The rain garden has been created as a demonstration project within the wider INTERACT-Bio project which is led by the global Local Governments for Sustainability network, ICLEI (International Council for Local Environmental Initiatives) (Ref. 1). As summarised by President of the Municipal Parks and Zoobotany Foundation of Belo Horizonte, Sérgio Augusto Domingues, “This is an important experiment that enables solutions based on nature. The idea is that it, like other mechanisms, complements macro-drainage interventions, helping the city to be more resilient to extreme events related to climate change" (Ref. 3).
According to the Municipality of Belo Horizonte, the Multiannual Government Action Plan (PPAG) aims to implement 30 rain gardens in the municipality by 2025, each garden having an area of ​​150 square meters (Ref. 7).

Extensive and low-lying, Suriname’s coastal region has been identified as highly vulnerable to climate-induced sea-level rise (Ref. 1). "Momentarily the most endangered community by sea-level rise in the whole of South America and the Caribbean", the Suriname Building With Nature project has seen "wooden, water penetrable dams...being built to trap sediment and replant mangroves" (Ref. 1). Prior to the implementation of the Building With Nature project, no mitigation measures had been undertaken to protect the area, and "human interference ha[d] converted mangrove areas to agricultural land, fishing ponds and settlements", with the loss of stabilisation provided by the mangroves meaning that "the coast has become susceptible to flooding and erosion, losing up to 27 meters of land in one year" (Ref. 1). It has caused "displacement of local habitants and loss of livelihoods, [with]...the local population...and its fisheries, farms, and important religious and cultural sites [being] at risk to frequent flooding and land degradation" (Ref. 1). The Building With Nature approach is touted as being "essential for mangrove and biodiversity conservation and the enhancement of the quantity of the blue carbon sequestered in coastal areas" (Ref. 2).

One of the first public institutions to rise to the climate change challenge in the Philippines is the LLDA, which unveiled a two-wing, four-story green building in Quezon City to mark its 48th anniversary in 2014.
Reflecting the critical mandate of the LLDA to protect the country’s largest freshwater lake, the LLDA building features its own water treatment facility, material recovery facility, and a rain collection system that can hold 60,000 gallons of water. In order to be certified by the Building for Ecologically Responsive Design Excellence, several greened areas have been installed in the building: two “pocket gardens” on intermediate levels and a green roof (Bio Roof) which covers an area of 208 m2. The Bio Roof is integrated within the building’s structure. Its vegetative layer protects the waterproofing membrane from climatic extremes, which allows for the reduction in maintenance and the reduction in the size of stormwater handling facilities. [1]
