The municipal government of the Yiwu city in China has launched the Green Lungs of the City Project (GLCP) in 2019. The overarching goal was to build a green lung, which will create more green spaces for residents in Yiwu, mitigate environmental pressures and improve the city's resilience to climate change. Under the project, a green corridor was created to reconnect the roads, rivers, ponds and lakes where different tree species were planted. Additionally, wetlands were constructed and restored to improve resilience against climate change disasters. The project is still in the ongoing phase, and a forest-wetland ecological park is under development in the city's central area. The GLCP aims to use different types of NBS elements to promote sustainable urban development and to provide multiple ecosystem services to the citizens in a highly urbanised area. [1]

Al Shaheed Park is the largest park in the country. The park was designed to include besides its green spaces, several buildings (museums, parking) populated with green roofs and an artificial lake. The size of the park with all the mentioned grey and green elements stands at 20 ha. The park is viewed as an encompassing part of a green belt that surrounds the city of Kuwait. From an environmental point of view, the park was built to protect the city from sandstorms and to reduce air pollution. From a cultural point of view, the park and the museums are providing the public with high-quality programs, events and spaces, and part of their mission is to spread awareness and educate the public on the importance of the country’s land, history and environment, in addition to the encouragement of international and regional exchange of arts. In addition, the park is meant to commemorate the victims of the first Gulf War. (1,2,3)

To mitigate environmental pressures, including air pollution and urban heat island effects and to improve urban resilience, the municipal government in Beijing has launched the largest afforestation Programme in 2012, Beijing Plain Area Afforestation Programme (BPAP). The aim was to create huge forest patches, develop urban forest park clusters and optimise the large-scale forest patterns. By 2015, BPAP has created green strategies with nine green wedges, multiple green belts, and green corridors around Beijing's old city centre. More than 70,000 hectares of forest (more than 54 million trees) have been planted, and the survival rate has exceeded 95%. BPAP has been considered one of the most ambitious projects for a high-density urbanised area like Beijing. [1, 5]

Climate change has become a constant topic for the administration of Israel, mainly due to the country's exposure to the effects of climate change. These include water shortages and pollution, the shrinking of the Dead Sea, waste production and disposal, air pollution and increased population density. Haifa is no stranger to these changes and the administration of the city is trying to align itself with international organisms that can help it to overcome such critical situations. The City of Haifa’s leadership strives to join the capitals of the world, share knowledge and establish operative cooperation. In December 2020 it joined the Paris Agreement, and in July 2021 signed the Urban Nature Declaration pledging a greener and more sustainable city with the 40C Cities Climate Leadership Group, an international organization of about 100 major cities worldwide. On a local level, the city initiated Haifa2030, a program that aims to prepare for global warming and to develop strategies for urban resilience. Among the actions taken into account by the municipality refers to green roofs, which the city intends to transform into an overall city program. Two demonstration roofs have been erected on municipal buildings, and additional roofs are planned. (2,3)

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)

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. [1]

The Urban Micro-Lungs is an Urban Living Lab project in the East of Amman, Jordan that applies the Miyawaki methodology for afforestation to create new green spaces. As part of the project special urban forests were created with the aim to improve the quality of life in dense and deprived urban areas, tackle climate change caused problems such as the urban heat island effect while also supporting local biodiversity. The project was initiated by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ) in cooperation with the Ministry of Environment and the Greater Amman Municipality, TAYYUN Research Studio (1,3,4). While the project was just completed in 2021, "the Urban Living Lab has shown the feasibility of creating green spaces even in adverse conditions characterised by dense construction, high degree of surface sealing and lack of open spaces."

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.
