Improved air quality

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.

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."

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).

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 Sustainable Residential Complex project was a measure taken by the city of Dubai, one of the largest city ecological footprints, with a goal to reduce it to the smallest ecological footprint by 2050. For the past two decades, the UAE government has made an effort to lower its own dependency on fossil fuels, shifting toward more environmentally-friendly sources to power its cities. The sustainable residential complex development project is one of the few initiatives taken by the city administration of Dubai under Vision 2021. Located just outside Dubai the area is the first operational net-zero energy residential complex in Dubai. [1, 2]

Ecosystem-based adaptation planning in Osh will support the Government of the Kyrgyz Republic in establishing its National Adaptation Plan (NAP) process and is consistent with the government’s strategic vision for climate change adaptation. Additionally, this project also contributes to the Green Climate Fund (GCF) and UNDP’s objectives by increasing resilience for the most vulnerable people, communities, and regions, by strengthening institutional and regulatory systems for climate-responsive planning and development, and by strengthening adaptive capacity and reducing exposure to climate risks. The priority sectors for the project are: (1) disaster and emergency management; (2) health; (3) biodiversity conservation; (4) and agriculture and irrigation water. The relevant agencies and stakeholders of these four sectors will be key to ensuring these plans catalyse investments to enhance adaptive capacity in the city. [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]

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].
