Around 90% of Guyana’s population lives in an area that is below sea level, with many inhabiting flood-prone areas along the coast. The coastal plains are also home to about 75% of the country’s economic activities, including almost all of Guyana’s agricultural production. Over the years, degradation and loss of mangrove forests have resulted in increased coastal flooding and saltwater inundation of agricultural land. Mangroves contribute substantially to sea defence in Guyana by damping wave action and reducing wave energy, trapping sediments and stabilizing shoreline substrates while playing an important role in carbon sequestration.
The Guyana Mangrove Restoration Project was executed during 2010-2013 under the National Agricultural Research & Extension Institute. Following completion of the Project phase and given the importance of mangroves to Guyana’s coastal defences, mangrove restoration and management were integrated into NAREI (the National Agricultural Research and Extension Institute), a national institution that promotes climate-smart agriculture and resilient citizens.

As of 2011, Windhoek, the capital of Namibia, has a population of approx. 330,000 people. By 2018, an estimated 40% of Namibia’s 2.4 million population were living in shacks and Windhoek makes no exception. Approximately 30% of the capital population lives in unplanned informal settlements struggling to access basic services such as water and sanitation. Worse than that informal settlements are especially vulnerable to environmental hazards: they are squeezed in next to each other on the slopes of mountainsides. When there's the occurrence of floods, they do so with such force and wash away people’s homes and their belongings. Even more distressing, people often lose their children due to rapid and unannounced flash floods. As a response to these threats and challenges the inhabitants of an informal settlement, Onyika (located in Okuryangava - which is a suburb of Windhoek, situated in the north of the capital city) paired with local authorities, donors and climate change experts to embark on a community-led process of creating a climate-resilient community. Being especially vulnerable to climate change, these forms of settlements require special attention in the development of climate resilience strategies. (1, 6)

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.

Santalaia is a high-end, multi-family residential building located in the heart of downtown Bogota, Colombia. Santalaia is often referred to as "the green heart of Bogota" and is seen as an icon of sustainability [1]. The 11-story building was completed in 2015 and all eleven floors are engulfed in many species of plant wildlife to encourage biodiversity. There are 115,000 native plants of 10 different species covering a total area of 3117 m² [2,3].
The plants included on the exterior of the building rely on a hydroponic system and provide a model of how to increase green zones in urban areas. A vertical garden of this size provides natural beauty in the middle of concrete Bogota while mitigating the carbon footprint of more than 700 people. An additional benefit of Santalaia’s vertical garden is that the plants create a “green carpet” that serve as insulation and reduce the use of air conditioners, an increasingly valuable contribution during times of rising temperatures due to climate change [5,6].

The Ecological Wetland Park is a 630,000 m2 artificial wetland located in a high tech industrial pioneer zone, adjacent to the Tianjin Harbor. The project was initiated by an agency of the local government and constructed with financial support from the Asian Development Bank (1). The area of the park used to be "a natural coastal salt marsh, which become reclaimed land in the early 2000s. The resulting saline-alkaline area had minimal ecosystem value and use value (as it was not considered to be suitable for agricultural activities either)" (1 p20). The wetland park's objective is threefold: 1) to provide a natural wastewater treatment plant for the industrial area to decrease pollutant discharge into the Bohai Bay and improve water quality; 2) to rehabilitating and restoring the once thriving biodiversity in the Harbor Area and the Hai river's estuary 3) to create a place for recreation and leisure for residents.

The Sino-Singapore Tianjin Eco-City (SSTEC) is a bilateral project between Singapore and China with a large scale private-sector involvement with the objective to "transform the 34 km2 barren, non-arable land and polluted wastewater ponds into ... a thriving city which is socially harmonious, environmentally-friendly and resource-efficient – a model for sustainable development for 350 000 residents. (1,2). The Eco-Valley is an S-shaped, 11 km green spine that runs through the whole Eco-City connecting its centre with sub-centres, all four residential districts, community spaces, multiple parks, commercial zones, and waterside areas as a scenic park providing a place for connectivity, transit, leisure and recreation for residents (1).

The green roof pilot project is part of eThekwini Municipality's Climate Protection Programme, initiated in 2004, it was focused initially on understanding the vulnerability of the city of Durban to the impacts of climate change. A strong emphasis has been placed on identifying climate change adaption projects that will improve the resilience of the city to future developmental, social and environmental challenges. Basically, the green roof pilot project is a response to the higher temperatures and increase in the frequency and severity of floods and droughts that are expected as a result of climate change. From an urban environment perspective, these changes will exacerbate the already high temperatures experienced as a result of the Urban Heat Island effect and the high levels of surface run-off and flooding that result from the hardening of permeable surfaces.

The City of Melbourne, through its Urban Forest Strategy, has a comprehensive plan for greening major streets and precincts, but not the smaller laneways. Across the municipality, laneways occupy a ground area of 60 hectares, with a further 150 hectares of space on the walls in these laneways (3). "The City of Melbourne has established the GYL program in 2016 with the vision to help transform the city’s smaller laneways into leafy, green and better usable spaces for the residents and other visitors to enjoy while addressing the city’s sustainability challenges." (1 p27). So far, a pilot project has been carried our including the transformation of 4 laneways: Coromandel Place, Guildford Lane, Meyers Place and Katherine Place (1,3). The intervention included an intensive planning process with the involvement of stakeholders from the private and public sectors and the creation of an interactive map of laneways ideal for greening. (1,2). The GYL program aims to address the issues of urban heat islands, climate change impacts of flood mitigation while also improving local aesthetics, amenity and creating opportunities for recreation (1).

In 2014 a counselling office of the NGO Green City was established, entitled The Greening Office (Begrünungsbüro), with the objective of better engaging citizens in green adaptation measures, such as green roofs, green façades, green walls or green courtyards (Reference 1, 5). Financed by the City’s Department of Health and Environment, the project addresses climate change adaptation through greening private properties, achieved through counselling citizens and companies, with diverse outreach and networking activities. The NBS recognised the potential of the many unused private spaces, such as south-facing facades and flat roofs to better adapt to climate change across the entire city (Reference 1).

Parc Marianne is an ecodistrict that aims to address multiple challenges such as climate action for adaptation, environmental quality, flooding, and in response to the high population growth in Montpellier. Parc Marianne is connected to public transportation, has bicycle lanes and car parks, and the sidewalk is shared between pedestrians and bicyclists and structured with trees and other greenery. The park was certified with the ecodistrict label in 2015 following requirements like environmental sustainability, thermal performance, quality of life, nature and biodiversity, and mobility (Ref. 1). Parc Marianne is a mixed neighbourhood with an ability to combine city and nature, quality of life and centrality (Ref. 2).
