Uruguay is highly vulnerable to climate change and its cities particularly vulnerable to the adverse effects of climate change, including extreme events such as droughts, floods, heat and cold waves, strong winds, tornadoes, hailstorms, frosts, heavy rains and severe storms. According to the latest census in Uruguay, more than 93 per cent of its population lives in urban areas. Montevideo is one of Uruguay's cities most affected by the changing weather. In 2014 most of the city has been left underwater after suffering its worst flooding in 50 years so much so that the city was declared a multi-hazard risk zone. Thousands of homes and businesses have been damaged in the process. This has been described as the worst flooding in almost a century. In 2018 the municipality developed the idea of rain gardens to counteract heavy rains and flooding effects. Initially, it was adopted in a number of neighbourhoods but over the years it has been extended to the entire area of Montevideo (1,2,3)

In 2019, in the city of Ulan-Ude, the most comprehensive and large-scale action "Green City" was launched [2,3,4,5,12], with the goal of creating an efficient and sustainable greening system in Ulan-Ude [1,7]. Nowadays, according to the city's norms, there are two times fewer green spaces per resident than is customary [7]. According to this program, by 2024, the provision of the population with public green spaces should be 10 sq. m per person [1,8]. Within the framework of the project, effective technologies for greening are already being introduced, and all green spaces growing in the city are being monitored [3,5,6]. Planting of green spaces is carried out under the guidance of the Scientific and Technical Council for the Integrated Greening of the City, which includes Buryat scientists and specialists from the City Administration [2].

The Mesurado mangrove forests, which is the focus point of the intervention, covers an area of approximately 6,760 hectares. It is situated within Montserrado County, around Monrovia, the capital city of Liberia, West Africa. It is surrounded by 38 human settlements some of which are regarded as slums. The area is currently one of those five Ramsar (Iranian city wherein 1971 was signed and ratified the Convention on Wetlands) designated sites in Liberia and a home of three species of mangrove that stands at the point of extinction due to human encroachment. (3) Adding to this, the area is used as a colossal waste dump, and, in cases, for cutting of mangrove trees for fish drying. In addition to the huge species richness of the area, it also serves as a habitat and breeding ground for marine species and provides a number of important ecosystem services. This intervention seeks to address the issue of ignorance on the part of the communities about the importance and benefits of mangroves in communities within and around the Mesurado wetland. As it is a soft measure project, the main implementation strategy includes a series of educational episodes through a system of religious conservation awareness and education and alternative livelihood options for the communities engaged.

The Anderson Road Quarry, once a vacant 40-hectare site is getting transformed into a sustainable residential neighbourhood while ensuring climate resiliency and low environmental impact in Hong Kong. The site will supply housing for 25,000 people. In addition to this, the city is employing a wide array of adaptive and resilient approaches including saving around 3,000 metric tons of CO2 annually, helping the city live up to its 65% to 75% carbon reduction goal by 2030 set in Hong Kong Climate Action Plan.

As a result of a ReefFix Project, an Integrated Coastal Zone Management (ICZM) Coral Reef and Mangrove Restoration and Watershed Management Demonstration programme, the Three Bays Marine Protected Area (MPA) and associated Integrated Coastal Zone Management (ICZM) Plan have been established in Haiti (Refs. 4, 5 and 7). Only the second MPA to be established in the country, the Three Bays MPA includes the bays of Limonade, Caracol and Ft. Liberté (the administrative capital of the Nord-East department of Haiti), as well as the Lagon aux Boeufs. As summarised by Ref. 8, the establishment of the MPA and ICZM "will help protect the mangroves, eel grass beds, reefs and habitats housing important fisheries that are crucial for providing livelihoods to nearby communities. It will also help protect the area from storm surges and provide local communities with ecosystem services such as carbon sequestration, tourism value and more". Additionally, the MPA will afford protection to numerous threatened species, "including sea turtles, whales, manatees and migratory birds" (Ref. 8).

Located in the heart of Hung Phu, a new urban area within Can Tho, K-Villa+ has been designed to "mak[e] the most of open and harmonious space[s] with nature, using green design solutions to improve bioclimatic comfort for users, while respecting sustainable values ​​and being friendly to the living environment" (Ref. 5). The low construction density of the building project has been coupled with prioritisation and installation of green areas both on the building itself and in the surrounding ground; permeable coverings to increase water percolation, and landscaping with native and climate-adapted trees and plants (Refs. 1 & 5.) An ecological pond has further been included in the landscaping of the villa's grounds and a rainwater harvesting system has been installed (Ref. 3). Through the application of these green design solutions, the urban heat island is considered to be reduced and bioclimate improved for those within the building, and biodiversity promoted through the planting of a variety of native species (Refs. 1, 2, 3 & 5).

Note that due to a lack of data, the exact point location of the villa is not depicted in the map below, but rather the new urban district, Hung Phu, in which the villa sits.

Battambang is projected to experience significant effects of climate change that will have a range of impacts including changes to hydrology and the frequency and intensity of flooding and droughts. As part of an Asian Development Bank project, a technical Climate Change Core Group was established to ensure that representatives from key sectors and levels of government work together to build resilience for the town and prepare the residents for the inevitable climate change impacts in the future. Three infrastructure systems in Battambang were identified for detailed vulnerability assessments and adaptation planning by the climate change Core Group; a) a long canal system to the west of the town, b) the riverbanks near the Sor Kheng Bridge in the centre of town, c) the train station and surrounding wetlands and settlements in the centre of town.

Tongnan Dafosi Wetland Park is located on both sides of Fu River flowing through the central area of Chongqing Tongnan District. Its south side is right next to the national tourist spot – the Great Buddha Temple (Dafosi). Due to the increasing frequency and severity of extreme rainstorms, the area is prone to floods. To build an urban wetland park that is adaptive to floods, designers retained the original wetland environment along the river channel and set up pedestrian corridors to enable citizens’ close contact with wetland nature. [1, 3] This project excavates two important cultural elements of Tongnan: 1) the shipping culture with a long history; and 2) the Buddhist culture based on the Great Buddha Temple. [1]

Once empty paved area between the houses on Marat Street in St. Petersburg now has been turned into a cosy green garden [4, 5, 6]. The project was developed by a group of students and initiated by the Green Petersburg Foundation, Plants for Friends, "Vladimirsky" Municipal District and others [1, 3, 4, 5]. The square landscaping project contributes to the city's adaption to climate change, a need to increase urban green zones, reducing excessive heat and rainfall levels, and the creation of habitat for birds, among others [3]. The square acquired the concept of a harmonious combination of natural motives and the mood of the Russian landscape [4].

The Ningbo Ecological Corridor is a post-industrial landscape ecological reconstruction project. It is located in the middle of the Eastern New Town in Ningbo, with a total area of 90 hectares [4]. Built upon a typical post-industrial site with degraded ecologies that needs to be healed and would soon become part of a new urbanized district, this project is holistic ecosystem services-oriented, introducing terraced wetland to manage elevation change of the site to slow the flows of urban runoffs from the street down to the river and remove the nutrients [1]. “Before being designed, the site and surrounding areas were fragmented farmland, villages and factories that were planned to be relocated - a typical brownfield in the rural-urban fringe of the southern region of China”[1]. With the implementation of the project, "the original channelized river is transformed into a meandering eco-friendly waterway dotted with tree isles to increase the interface between organisms and water bodies to empower the river’s purification capacity. The project uses productive crops and annual flowers that are rotated to bring seasonal surprise and agricultural vitality to the growing city. Boardwalks are designed to allow visitors to have intimate experience of nature and the nostalgic pastoral landscape. Pavilions made of corten steel floats on wetlands and terraces, giving the ecological corridor a touch of contemporary urban life and art. [1] "As a result, this project demonstrated landscape as an ecological infrastructure that heals the degraded ecological system meanwhile provides social and cultural services to the establishing communities."
