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).

Peru has seen a sharp increase in major flooding, prolonged droughts and water scarcity of supplies in the dry season, negatively impacting agriculture, migration, conflict and economic growth in recent years. As 71% of the world's tropical glaciers are found in Peru these climatic changes affected the country profoundly leading to a decrease in the glacial surface and creating unstable lagoons also causing natural disasters such as alluvium landslides and deadly flash foods. Glacial melt is also disrupting water flow and quality, posing a threat to the flora and fauna that rely on freshwater environments. Unsustainable management of fragile glacier ecosystems is causing environmental degradation and biodiversity loss. To counteract many of these challenges and to safeguard the communities that are in peril, in 2011, the Government of Peru together with a number of stakeholders, initiated an intervention to sustainably manage more than 200 new lakes that affect directly populations in different cities in the Ancash, Cusco and Lima regions, Huaraz being one of the cities targeted. The project benefitted downstream communities and protected fragile high-altitude freshwater ecosystems. (1,2)

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.

St Inez creek was an ecologically functional tidal waterbody in Panaji, Goa. Panaji has been identified as one of the most vulnerable coastal cities from floods due to the predicted sea-level rise. St Inez creek is one of the very important freshwater bodies in the city because of its cultural, social and biodiversity value. Recently, the ecological functionality of the creek was severely compromised through a combination of natural degradation and anthropogenic influences, which includes sedimentation, collapsed embankments, eutrophication, weed growth, pollution, the release of raw sewerage from neighbouring informal settlements and dumping of construction debris. The current intervention is about the restoration of the creek to conserve the urban nature and ecological systems and to increase the resilience of the city. [1, 2]

The city of Algiers initiated in 2010 a project in order to establish a green belt around its areas and some northern municipalities. The project aims to create agro parks, allotment gardens as well as parks as a strategy for reintegrating the concept of the green belt into the Algerian territory. Through this intervention, the municipality aims to put into practice environmental values ​​linked to improved quality of life and social well-being, for the benefit of the local community. The intervention plans to introduce different species of trees and include for the first time in Africa agro parks as spaces which are designed to reconcile urban and agricultural functions in a win-win strategy. The action was thought to respond to the impacts of climate change in the country, which faces rain events that are less frequent but more intense, and droughts that are more common and longer.

Kaysone experiences severe flooding events on an annual basis due to its location to the banks of Mekong river, as well as periodic storms, and past responses to these threats have focused on the Savanxay Market and the Southern Flood Gate, but with limited success (Ref. 1). This intervention focuses on the development of an integrated adaptation plan for the area around the market and adjacent to the Mekong canal. This plan includes NBS-specific components considering how the market's parking area provides an important opportunity for bioengineering and green cover, and that there is "an opportunity to use adjoining land as a constructed wetland and park for recreation, flood retention and storm water treatment" (Ref. 1). The adaptation plan comprises seven points overall, focusing on wastewater recycling, walking paths, proper drainage and green space in addition to an educational component related to climate change and its impacts (Ref. 1).

The Krubong landfill site has been proposed to undergo a "thorough and safe environmental rehabilitation program[me]" so that the site can be developed as a public park (Ref. 1). Following completion of a feasibility study, it is envisaged that significant rehabilitation work to address environmental degradation and restoration of natural habitats will be required, after which the site will be developed into a public park (Ref. 1). The programme remains in its planning stage, but seeks to address Sustainable Development Goals (SGDs) 11.6 and 15.1 through protecting, restoring and promoting sustainable use of ecosystems and reversing land degradation and/or biodiversity loss; and reducing the environmental impact of cities by paying special attention to waste management and providing access to safe, open public spaces (Ref. 1). At a more local level, the programme intends to complement additional programmes laid out in Melaka's Resilience strategy document, including promoting both cycling and pedestrian networks and reshaping public spaces in the city (Ref. 1).

A greening project in Laval aimed to replace impermeable surfaces such as asphalt with vegetation. This process would allow water to infiltrate the soil on a surface area of 3000 square meters and plant 7200 plants on land located near or inside urban heat island zones of the city (Ref. 1,2,3,7). The project takes an integrated approach to mitigate the impact of urban heat islands, which make up 12-13% of the territory in Laval (Ref. 1,7). Particular focus of this project is placed on planting on sites of vulnerable communities (Ref. 1,3).

The green belt was created not only as an aesthetic element but also to serve as the lungs of the city. The forest planting works around Nur-Sultan have been carried out since 1997 [6, 7]. The area of ​​the green belt of Nur-Sultan is 100 thousand hectares, of which 15 thousand hectares are planted within the city limits. The main idea of the project was to provide comfortable conditions for the residents of Nur-Sultan city, which would serve as a mechanism for improving air quality, mitigating climate and as a natural barrier to protect the city from dust winds and snowstorms [2, 4, 5, 6, 7]. An important aspect that was taken into consideration are the animal species of the forest, as the territory of the green belt is inhabited by foxes, hares, corsacs, white and grey partridges, roe deer, wild boars, etc [1, 2, 7, 8]. The primary importance of biodiversity efforts is assigned to the breeding of birds, especially pheasants [1, 2, 3, 4, 5], as pheasants are an element of local cultural heritage, and on the territory of the green belt, traditions and cultural events related with the pheasants are organised every year [2, 4]. The young forest should turn into an improved recreation area, a favourite pastime for city residents at any time of the year [2,7].
