Park Podnikolie, with an area of about 100 hectares, is part of the water-green frame of the city and is included in the conservation zone of the historical and cultural value of the city of Mogilev [4,11]. Since olden times on the territory of Podnikol, there were up to 400 manor plots, occupied mainly by vegetable gardens. Now Podnikolie is a large park, which has become a favourite place for residents and guests of the regional centre [1]. More than 1125 tree saplings have been planted on the territory of Podnikolie to preserve the integrity of the historical ground, the historical territory [1,9,10,11]. Thus, the park is also called the "green heart" of Mogilev city. The densely planted area is officially a quiet recreation area where people "merge" with nature [1,2,6,10]. The project's goal is to improve the urban management system, promote the implementation of the principles of green urban planning, and improve citizens' quality of life through effective cooperation between local authorities and the population [2,9,10].

As part of the "Urban Forest Policy", the first Miyawaki urban forest was created in an area of 2,850 square meters in Lahore, Pakistan. The initiative was a result of a public-private partnership between Lahore Development Authority (LDA) and Restore Green. The project was carried out under the PM Khan 10 billion tree plantation drive. Miyawaki is a technique pioneered by Japanese botanist Akira Miyawaki, which helps build dense, native forests. The approach is supposed to ensure that plant growth is 10 times faster and the resulting plantation is 30 times denser than usual. It involves planting dozens of native species in the same area and becomes maintenance-free after the first three years. [1, 2, 3]

As a solution to the increasing population, pollution and high energy consumption, the municipal government of Shiraz has launched the Green City project in 2008. The main aim of this initiative is to reforest the city's periphery and encourage citizens to plant gardens on rooftops and the private sectors to adhere to the city’s development plan with all construction projects.

Recognising the benefits which urban forests bring to its citizens, Salvador has committed to protecting and restoring the Atlantic Forest, and has developed its own local framework which goes beyond national requirements (Ref. 1). The city has launched several programmes under its 'Salvador, Capital da Mata Atlantica' initiative, which together aim to restore the forest which has "suffered from severe deforestation" (Ref. 1). Included under the umbrella initiative are programmes such as the "'Delivery of trees', recovery of parks and collective planting" (Ref. 4).

The intervention targeted a section of the Dominguez Creek for restoration, with the aim of achieving a "multi-benefit project [which] creates passive and active recreation opportunities for park-poor communities, reestablishes native riparian plantings and captures stormwater before entering the channel along the Dominguez Creek in cities of Gardena and Hawthorne" (Ref. 2). Previously being characterised by the local community as a “Triple U” (Undesirable, Unsafe and Unusable) area, the project aimed to support a variety of environmental, sustainability, and humanitarian activities (Ref. 1). The nature-based solution interventions which were implemented as a result of the project mainly pertained to the planting of in situ trees, shrubs and groundcover plants; restoration of the riparian habitat; temporary installation of a "mini-urban forest for a shaded respite from the harsh downtown streetscape"; aiding in stormwater capture; conservation of water resources through using native plant species; and creating "watershed awareness" (Refs. 1, 2, 4, 5 and 8).

Senegal, like many other West African countries, is in an unprecedented position when it comes to the threats climate change poses. Climate scientists predict that the country will likely experience increased temperatures, decreased annual rainfalls, a rise in sea levels, and an increased frequency of heavy rainfall events. Automatically these events will change drastically the social and economic structures of the country and are reasons for concern for the people of Senegal and their government. For example, the city of Thiès is in an area where environmental degradation is very advanced. The tree cover is in a situation of extreme fragility due to tree ageing or abusive tree cutting. To address many of these concerns, the city of Thies is trying to become sustainable through the development of green spaces that are expected to restore the city's ecological dimension and contribute to the reduction of greenhouse gases and the improvement of the living environment.

The City of Fort Collins is "taking steps to restore flows, fish passage, and ecological function" of Colorado's Cache la Poudre River (Ref. 6). The river was "heavily manipulated for irrigation and mining" throughout the early 20th century (Ref. 6), and today continues subject to the impacts of gravel mining, agriculture and urbanisation (Ref. 1). Regional climate change predictions further complicate our ability "to understand how the river’s hydrology and ecology may respond to warming climate scenarios" (Ref. 1).
The City of Fort Collins was, therefore "invested heavily in this urban river through extensive planning efforts, purchase of approximately 700 hectares of lands within the river’s floodplain, projects to address stormwater control and conveyance, water quality management, and acquisition of in-stream flow water rights", and in 2011, the City’s Natural Areas Department published the Cache la Poudre River Natural Areas Management Plan which outlined "opportunities and challenges in supporting the river’s ecological function and reducing risks to life and property during significant flood events", particularly through the implementation of nature-based solutions (Ref. 1). A suite of nature-based solutions has since been proposed and implemented by the City of Fort Collins, two of which are the Sterling Pond Ecological Restoration (also referred to as North Shields Ponds), and the McMurry Natural Area Ecological Restoration (Refs. 1 and 2).

Campinas is a fast-growing city and like many cities in Brazil, it confronts itself with many climatic incidents linked to a hotter and drier climate. In Campinas, in spite of the good performance of the city and the region in economic areas, there is a historical lack of urban landscape planning that integrates adequate social housing and areas that should be protected, such as riparian corridors, ecosystem remnants and other relevant green areas that offer ecosystem services in the urbanised context. Campinas has developed plans, projects and programmes to tackle regional, municipal and local issues related to environmental quality and offer green areas to the least privileged residents. Ecological corridors are being designed to connect forested fragments and/or relevant ecological areas to enable the genetic flow. The municipal green plan adopted the concept of a connectivity line to promote ecological corridors. (1,2)

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)

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)
