Under Sustainable Development Goal 11 (make cities and human settlements inclusive, safe, resilient and sustainable) in 2017 a coalition of stakeholders including the Municipality of Asuncion started the implementation of an initiative focused on improving the quality of life in the Metropolitan Area of Asunción through green infrastructure in a sustainable and resilient city framework. Why Asuncion? Cities and metropolitan areas are fundamental centres of economic growth: they contribute approximately 60% of world GDP. However, they also account for around 70% of global greenhouse gas emissions and more than 60% of resource use. Asuncion makes no distinction - it is a city with a high flow of cars and transportation, irregular flooding (the sewerage system there has already been exceeded for some time), and urban growth. Trying to respond to some of these challenges, the present intervention has been proposed with a duration of 5 years. (1,2)

Eco-district creation in Ulaanbaatar comes under the Ulaanbaatar Green Affordable Housing and Resilient Urban Renewal Project (AHURP). The planned development areas are hotspots of greenhouse emissions and air pollution, mainly due to the widespread use of coal for heating and cooking. The project will transform the highly climate-vulnerable and polluting "ger" areas (traditional Mongolian tents) into zones that are low-carbon emitting, climate-resilient and affordable. This will be done through low-cost urban infrastructure, public facilities, and social housing units. The project's five phases will deliver about 20 eco-districts or sub-projects, with each covering an average of 5 ha. The project is a large-scale demonstration initiative that will leverage private sector investment to deliver affordable and green housing stock, and redevelop "ger" areas into urban areas that are resilient to climate change, contribute to decreased air and soil pollution, and will provide a liveable urban environment to "ger" area residents. It will also establish policies, mechanisms, and standards for sustainable affordable housing and green urban redevelopment. [1, 2, 3]

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)

Resilient Islands is a project thought and directed by the Nature Conservancy (TNC) and the International Federation of the Red Cross and Red Crescent Societies (IFRC) in 3 Caribbean island nations. It is a project at the intersection between conservation and disaster risk reduction and it comprises actions implemented in the Dominican Republic, Granada, and Jamaica. The negative impacts of climate change are already affecting people, homes, businesses and infrastructure in Caribbean nations. In response to increasingly dangerous hurricanes and rising vulnerability, Resilient Islands will address the need for urgent action by developing adaptation toolkits, best-practice models and access to funding. Caribbean nation islands are the world's most vulnerable to the impacts of climate change. Coastal flooding and erosion caused by hurricanes and severe storms threaten lives, homes, jobs, and infrastructure. Grenville is a coastal town, the second largest town in Grenada, with a population of around 2,400. It is highly susceptible to flooding and has seen increased coastal erosion in recent years due to the degradation of the fringing reefs, its first line of sea defence. Since 2017, TNC and the IFRC have collaborated with governments, communities, and partners in Grenada and Greenville to develop national plans for a more sustainable future through nature-based disaster risk management and there this is how this intervention was born.

The Democratic Republic of the Congo’s coastal zone stretches 40 km and comprises the towns of Muanda, Banana and Nsiamfumu. The problem of coastal erosion has intensified since 1980 with the significant retreat of the coast in the Banana-Muanda segment, this retreat has been estimated as much as 2,300 meters. According to the report of the second national communication on climate change (2010), the Democratic Republic of Congo’s coastal zone, with a coastline of about 40km, is facing coastal erosion due to a combined effect of topography, sandy nature of the soil and ocean dynamics (height and direction of the swell, tide height, current velocity, storms etc.). With the rate of shoreline retreat that is likely, it is expected that the road between Banana-Muanda will be completely lost between 2050 and 2100. The proportion of lands lost to encroaching sea will double (200 m around Nsiamfumu and 100 m between Muanda city and Banana). In total, DRC can expect to see the reach of its coastal zone reduced from 50-100 m by 2100. To respond to some of these complex challenges the Department of Environment, Nature Conservation and Tourism, Democratic Republic of Congo implemented the present intervention partnering with the United Nations Development Programme (UNDP) and the Global Environment Facility (GEF).

Douala is the economic capital of Cameroon and one of its largest cities. The city is located on the banks of the Wouri River (hence a port city) and its climate is tropical. The marine and coastal biodiversity of Cameroon is rich and diverse, and it is highly endangered because of human activities including artisanal and industrial fishing and pollution generated from industries, accidental loss of crude oil in transit or during loading or unloading. In Douala, thousands of inhabitants have settled in and around the mangrove swamps, destroying the mangrove ecosystem and endangering biodiversity including snakes, birds, fish, trees and frogs. Biodiversity studies are rare, and even if they exist, they are done in part and do not give an overview of the real state of biodiversity in the city. The city of Douala is full of many ecosystems of various natures (micro-ecosystems), each of which has species adapted to the environment. Besides this, Douala confronts itself with seasonal flooding and high temperatures due to climate change. In response to some of these challenges, a local entity, the Association of academics and researchers for Biodiversity conservation, initiated in 2020 an action that focused on environmental education and biodiversity conservation. The initiative also provides a framework for reflection and exchange on biodiversity issues. (1,3,4)

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.

Ecuador is considered one of the most biodiverse countries in the world (one of the 17th most diverse), due to the high diversity of their natural species. The country has around 23.056 taxonomic species of animals and plants reported, which constitutes the 6,1% of all species reported worldwide. (6) Quito, the country's capital makes no exception and is considered a biodiversity hotspot. In recent years, urban expansion has had a detrimental effect on the environment and the city’s ecology. All of these actions exacerbate the stresses on the different ecosystems, contaminate water sources and networks, and put the city’s capacity to supply ecosystem services at risk. To respond to many of these challenges the municipality of Quito initiated in 2020 a nature-based solution program under the EU framework of Clever Cities. (1) The project intends to position nature-based solutions as a means to improving public health, social cohesion, citizen security and increasing economic opportunities in those areas. (3)

The Jerusalem Forest is located southwest of Jerusalem and is the green lung of the residents of Israel's capital. The forest has a variety of trees, flowers and wildlife, remains of ancient farming implements and burial caves (2). The forest was planted in the 1950s in an attempt to increase the green cover and natural biodiversity of the area. However, due to intensive urban development including road constructions and energy grid installation and forest fires the size of the forest has been shrinking once covering 4 700 000 m2 to the current size of 1 250 000m2. In 2016, a non-governmental green organisation initiated the renewing of the Jerusalem Forest with the aim to preserve the forest, halt its decrease, secure its sustainable maintenance while involving the public in the conservation efforts increasing their environmental knowledge about their local habitat and support nature stewardship through the application of a community forest model.
