The Mesurado mangrove forests, which is the focus point of the intervention, covers an area of approximately 6,760 hectares. It is situated within Montserrado County, around Monrovia, the capital city of Liberia, West Africa. It is surrounded by 38 human settlements some of which are regarded as slums. The area is currently one of those five Ramsar (Iranian city wherein 1971 was signed and ratified the Convention on Wetlands) designated sites in Liberia and a home of three species of mangrove that stands at the point of extinction due to human encroachment. (3) Adding to this, the area is used as a colossal waste dump, and, in cases, for cutting of mangrove trees for fish drying. In addition to the huge species richness of the area, it also serves as a habitat and breeding ground for marine species and provides a number of important ecosystem services. This intervention seeks to address the issue of ignorance on the part of the communities about the importance and benefits of mangroves in communities within and around the Mesurado wetland. As it is a soft measure project, the main implementation strategy includes a series of educational episodes through a system of religious conservation awareness and education and alternative livelihood options for the communities engaged.

The Jerusalem Forest is located southwest of Jerusalem and is the green lung of the residents of Israel's capital. The forest has a variety of trees, flowers and wildlife, remains of ancient farming implements and burial caves (2). The forest was planted in the 1950s in an attempt to increase the green cover and natural biodiversity of the area. However, due to intensive urban development including road constructions and energy grid installation and forest fires the size of the forest has been shrinking once covering 4 700 000 m2 to the current size of 1 250 000m2. In 2016, a non-governmental green organisation initiated the renewing of the Jerusalem Forest with the aim to preserve the forest, halt its decrease, secure its sustainable maintenance while involving the public in the conservation efforts increasing their environmental knowledge about their local habitat and support nature stewardship through the application of a community forest model.

Located in the heart of Hung Phu, a new urban area within Can Tho, K-Villa+ has been designed to "mak[e] the most of open and harmonious space[s] with nature, using green design solutions to improve bioclimatic comfort for users, while respecting sustainable values ​​and being friendly to the living environment" (Ref. 5). The low construction density of the building project has been coupled with prioritisation and installation of green areas both on the building itself and in the surrounding ground; permeable coverings to increase water percolation, and landscaping with native and climate-adapted trees and plants (Refs. 1 & 5.) An ecological pond has further been included in the landscaping of the villa's grounds and a rainwater harvesting system has been installed (Ref. 3). Through the application of these green design solutions, the urban heat island is considered to be reduced and bioclimate improved for those within the building, and biodiversity promoted through the planting of a variety of native species (Refs. 1, 2, 3 & 5).

Note that due to a lack of data, the exact point location of the villa is not depicted in the map below, but rather the new urban district, Hung Phu, in which the villa sits.

Once empty paved area between the houses on Marat Street in St. Petersburg now has been turned into a cosy green garden [4, 5, 6]. The project was developed by a group of students and initiated by the Green Petersburg Foundation, Plants for Friends, "Vladimirsky" Municipal District and others [1, 3, 4, 5]. The square landscaping project contributes to the city's adaption to climate change, a need to increase urban green zones, reducing excessive heat and rainfall levels, and the creation of habitat for birds, among others [3]. The square acquired the concept of a harmonious combination of natural motives and the mood of the Russian landscape [4].

Touted as a long-term solution to flooding of Mandaue City, establishment of a mangrove eco-park has begun, having received funding from the Department of Budget and Management (DBM) (Ref. 1). Through establishment of mangroves, the eco-park will "perform a significant role in shoreline protection, acting as a buffer against strong winds and waves", which is considered particularly important in light of the anticipated effects of climate change (Ref. 6).

A total 17-hectare plot is to be rehabilitated, as identified in the Mandaue City Government's Comprehensive Land Use Plan (Ref. 3). At present, it is unclear whether nature-based solutions (including mangrove restoration) are to be implemented across the entire 17ha of the site, but initial efforts have been focused on the restoration of a 5-ha section of mangrove forest (Ref. 2). Due to the lack of data on how exactly the remainder of the 17-ha area will be restored, the total NBS area for this project has only been recorded as 5-ha (5000m2) within this case study, rather than the entire 17,000m2 which is encompassed within the site.

The site is situated at the outfall of the Butuanon River which frequently overtops as a result of heavy rain and has been considered "biologically dead" since 1992 (Ref. 7). The site itself comprises a former dumpsite which had been "left derelict and filled with piles of trash", hence in addition to reducing flood risk, its rehabilitation will serve as green space in which "the residents of Mandaue City [can] gather and enjoy a breath of fresh air" (Ref. 2). The eco-park is considered to bring the added benefit of filtering water as it enters the Mactan Channel, in addition to reducing greenhouse gas emissions through carbon dioxide absorption (Refs. 1 & 6).

The Porsuk Stream divides the city of Eskişehir into two with a green corridor running along the shores of the stream. The Porsuk Stream served provisioning services and acted as a recreational area in the first half of the 20th century, however with increased industrial activities discharging untreated wastewater into the river, rapid urbanisation in the city and other settlements, and increased fertilisers and pesticides in the groundwater originated from agricultural practices (upstream of the Porsuk River), it became highly polluted and its ecosystem degraded severely (1,2,4,5). The Organization for Security and Cooperation in Europe (OSCE) identified the stream as one of the highly dangerous rivers in terms of pollution and health, where no living beings except viruses live (1).
Within the framework of the 'Eskişehir Urban Development Project' the 'Natural Disaster Loss Reduction Project (Porsuk Project)' has been initiated focusing on the ecological restoration of the stream, improving water quality, increasing the resilience of the city against natural disasters (as earthquakes and floods) while also reestablishing the stream's environmental and social role in the city (1). A network of natural infrastructure was created along the Porsuk by expanding public green spaces and link the entire corridor with a sustainable public transport network. (4,5)

The Orbital Forest of Tirana is an innovative urban forest that as a green belt forms a natural growth boundary for the City. Tirana has experienced rapid development in the past decades that led to population growth challenging municipal services and infrastructure, while climate change also posed extensive pressures to the urban area with intense flooding, precipitation, urban heat and degrading environment (1, 4). The Orbital Forest is a ring on the periphery of the City that connects 14,000 ha of Tirana’s parks, agricultural fields, and forests, maintaining the ecosystem and supporting biodiversity. (3, 4) The NBS aims to increase urban greenery through the plantation of 2 million trees that fit well to the existing ecosystem while also creating a natural boundary to halt urban sprawl (1,4,5). The afforestation of the Orbital Forest has been done through the “Donate a Tree For Tirana” campaign started in 2017 where citizens, businesses and international organisations can plant a tree adding to the green belt. As of 2021, more than 440,700 trees in the framework of the "Donate a Tree" campaign are also bringing urban nature closer to residents (3).

A multi-purpose green belt (12 km in length of Batticaloa Municipal Corporation coast) was established to protect the lagoon and coastal areas, restore mangrove ecosystems and improve coastal biodiversity. The project comes under activity 1.3 of the overarching project Climate Resilient Action Plans for Coastal Urban Areas in Sri Lanka (CCSL). The project focuses on the most urgent and immediate needs of the Sri Lankan coastal cities in adapting to climate change, and mitigating risks and the severity of impacts through Disaster Risk Management (DRM). The green belt plantation was done with Casuarinas plantation in 400 ha (out of which 75% by Mandru and 25% by the Forest Department), mangrove forest redesigning and protection of the existing vegetation.

Hatirjheel area development project is a wetland restoration project that explores the possibility of reintroducing water edge elements into the city of Dhaka. The project includes both engineered infrastructure and NbS. The restored jheel (wetland) and Begunbari khal have improved storm-water management of Dhaka and made aquatic biodiversity better. It also increased green and open space in the busy capital. The intended objective of the project was to create a bridge between the densely developed old part of the city on the south and the new organised north part of the city. Spreading over 311 acres, this project has endeavoured towards improving connectivity between major urban corridors as well as acting as a retention pond to mitigate the flash flood-prone densely populated part of the area.

In 2014, a rooftop farming project was initiated in the informal settlements of the Greater Cairo Region to address challenges brought by climate change and to empower the local community. The project was initiated by the German Corporation for International Cooperation and a local NGO with the objective to "reduce ambient temperatures (microclimate) in a densely populated area through green spaces on rooftops, and reduce the impacts of the urban heat island effect and increasing heat." (1) The initiative also addressed four of the Aichi Biodiversity Targets by tackling biodiversity loss, encouraging sustainable agriculture practices, fostering ecosystem services and developing local knowledge (1,11)
Besides environmental benefits, the project and its scaled-up project in 2017 brought several socio-economic benefits by reducing vulnerability to food price changes and by developing the local community. Rooftop Farming Hubs were also established to foster the training and knowledge sharing of rooftop farmers in Cairo (1).
