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).

Kempegowda International Airport Bengaluru (KIAB)'s new terminal 2 is an environmentally friendly initiative that uses innovative methods to maintain ecological sustainability using native plants (Ref 1, 2). The terminal was built on four guiding principles: technology leadership, being a terminal within a garden, environmental and ecological stewardship, and a celebration of Karnataka’s rich heritage and culture. Through the "terminal within a garden" project, the aim was to create a calming and relaxing space for passengers using greenery for visual appeal as people pass through the airport (Ref 1). Hanging gardens, trees, and green walls are the primary nature-related features included in the terminal and an outdoor greenbelt around the terminal. The airport uses native plant species, including trees, flowering plants, and shrubs (Ref. 2).
The terminal area also includes water bodies, cascades, and miniature waterfalls to maintain the natural atmosphere. The terminal also has extensive rainwater harvesting and groundwater recharge facilities (Ref 1). Other sustainable goals in the terminal area include energy saving, water conservation, waste management, and pollution control measures (Ref 2).

The Community Garden Project was proposed in 2018 by Samyuktha Kannan (a resident of Chennai City) to the Resident Welfare Association (RWA), which is a non-governmental organization (NGO) of Kasturba Nagar (1,2,3). The RWA uses the community hall of a public park of Kasturba Nagar to host meetings and community events, but the area was surrounded by open dry land and an unmanaged field (1,2). This open area surrounding the community hall was then assigned to develop a community garden of 1500 square feet (1,2,3). This project aimed to serve as a shared garden place to bring along residents of all age groups to enjoy gardening and simultaneously create opportunities to learn and share knowledge through social engagement and reconnect with nature (1,2). Although implemented and completed in 2019, the project still continues to contribute towards sustainability through further development and introduction of eco-friendly elements and activities, as well as the involvement of various stakeholders for support (3,4).

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.

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).

The Rioni River basin is the second largest in Georgia, originating in the Greater Caucasus range and flowing into the Black Sea, traversing the town of Samtredia. Samtredia has been affected directly on many occasions by floods that have become a current occurrence in the Rioni River basin as of late. The underlying causes of vulnerability to climate change in the Rioni basin can be categorised into 1) physical factors –direct manifestations of climate change, 2) factors caused by anthropogenic intervention – those related to the harmful ways in which humans have and continue to interact with the environment which has exacerbated vulnerability and 3) Institutional factors – related to the legislative/regulatory barriers placed by government and other institutions, as well as limited capacity (human and resources) to manage climate change vulnerability. Flooding has been harmful not only to the local population but also to the biodiversity of the area, which suffered losses and an ecological imbalance and a disruption in the habitat patterns of local fauna. Many of these issues became the focal point of an activity developed by the Adaptation Fund alongside the Georgian government as early as 2012. The intervention stretched for 4 years and involved several localities in the Rioni River Basin, including Samtredia municipality, consisting of creating bank terracing, vegetative buffers, and tree revetments in order to address floods related to the Rioni River basin and the localities it traverses.

The Beddagana Wetland Park is located in Sri Jayawardenapura Kotte, Sri Lanka's administrative capital. The wetland park plays an important role in flood regulation and keeping the city cool during periods of extreme heat. The city is located in the Colombo district and the project contributes to the flood management goals of the Metro Colombo Urban Development Project (MCUDP). It demonstrates how a wetland can be preserved while promoting eco-tourism and improved livability in the city. The target area is located within the Sri Jayewardenapura-Kotte municipality and is a part of Parliament Lake. While focusing on the protection of the wetland habitat as a flood-retention area, the project also supports selecting investments aimed at the protection and landscaping of key areas within the target area to improve livability for local people living in and around the area, while providing access to much-needed recreational space.

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).

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.

Kampala called ‘The Green town’ its capital and the most important city in Uganda. The town nearing the Lake Victoria into the South, depicts both colonial and contemporary architecture and has a population of approximately 2 million people, spread over 21 slopes. The city also has a continuous flux of human capital (caused by the effects of climate change- e.g. droughts, erratic rains) from the country's rural regions which puts a tremendous amount of pressure on the environment, through inefficient resources and unstastainable settlement patterns. As a response, the city of Kampala tried to address climate change mitigation by initiating a large tree planting project in Kampala and its outskirts. (1,2) The plan identified “proper management of urban natural assets” and the planting of 500,000 trees as ways for Kampala to become a lower carbon and more climate-resilient city. One of its desired impacts was “increased green spaces and trees in households for improved health and income”. (3)

A green wall of 73 square metres was constructed on the building of the Federación de Entidades Empresariales Privadas de Cochabamba (FEPC, the Federation of Private Business Entities of Cochabamba) (Ref. 1). The vertical ecosystem comprises over 3000 plants of 35 species and is considered the first vertical garden to have been created in Bolivia (Ref. 1). The green wall is considered to have 'beautified' the city of Cochabamba, but is also considered to "contribute... effectively to the preservation of the environment" (Ref. 2).
