Increased visibility and opportunity for marginalised groups or indigenous peoples

The Upper Kinta River Basin covers an area of about 31,470 hectares above Ipoh City, and it is the main water catchment resource for the residents of the city and its surrounding areas. The Kinta river basin is now threatened by land erosion, land development, improper sewage treatment and irresponsible waste discharges (Ref 1). In 2021, a pilot project was implemented near the city of Ipoh along the SimpangPulai Highway and experimented with river bio-engineering techniques to reduce soil erosion and subsequently prevent sedimentation downstream (Ref 3). The pilot site was established as part of the Mainstreaming Biodiversity Conservation into River Management project, which focused on applying nature-based solutions for mainstreaming biodiversity into riverine landscape planning and watershed management in Malaysia. To provide seedlings for the bio-engineering project and also other related initiatives, a nursery was established in the indigenous Pawong Orang Asli Village. The nursery also provided additional income for communities (Ref 4). The pilot was developed with the expectation to be upscaled and replicated in other parts of the UKB, especially along the SimpangPulai Highway. (Ref. 6)

The Adopt-a-Park project is an urban re-greening and renewal program. The Metro Manila Development Authority (MMDA), working together with the 17 Metro Manila local government units (LGUs), has launched the initiative to address rapid urbanization and urban decay by creating new green areas and renovating existing but underutilized or derelict neighbourhood spaces [4]. The project is part of the "I ♡ Metro Manila" advocacy program of the MMDA, which was launched to "uplift the spirits of the residents recovering from the impact of the COVID-19 pandemic as well as to strengthen initiatives on urban renewal that aims to transform the metropolis to be a more livable, greener, and resilient region"[1].

The main rivers that cross Lilongwe are the Lilongwe, Lingadzi, Nankhaka and Chankhandwe Rivers, of which the Lilongwe River is the biggest and longest river and the primary source of water for Lilongwe city's residents. At 200 km long, besides its primary function, the river also supports several informal settlements and provides ecological, recreational, cultural and economic benefits. Despite these important functions that the river offers, it is still facing threats such as pollution, urban agriculture, sand mining, climate change effects, and a loss in the biodiversity of fauna and flora that this watercourse hosts. As it sustains a population of approx. 1 mil. inhabitants, the local authorities were interested in finding solutions to address the above threats. As early as 2016, ICLEI ( Local Governments for Sustainability), an international NGO that promotes sustainable development, worked alongside Lilongwe City Council and other stakeholders to protect the river as well as the people depending on it and implemented several actions, with the help of the local community. Eventually, this collaboration led to the issuing of a strategic plan for a sustainable and functional ecological corridor system in the heart of Lilongwe City. The Ecological Corridor aims to transform Lilongwe into a green, clean, prosperous, and resilient city, by ensuring the protection of its urban natural assets, and advancing complementary nature-based solutions. 1,2,3)

The Democratic Republic of the Congo’s coastal zone stretches 40 km and comprises the towns of Muanda, Banana and Nsiamfumu. The problem of coastal erosion has intensified since 1980 with the significant retreat of the coast in the Banana-Muanda segment, this retreat has been estimated as much as 2,300 meters. According to the report of the second national communication on climate change (2010), the Democratic Republic of Congo’s coastal zone, with a coastline of about 40km, is facing coastal erosion due to a combined effect of topography, sandy nature of the soil and ocean dynamics (height and direction of the swell, tide height, current velocity, storms etc.). With the rate of shoreline retreat that is likely, it is expected that the road between Banana-Muanda will be completely lost between 2050 and 2100. The proportion of lands lost to encroaching sea will double (200 m around Nsiamfumu and 100 m between Muanda city and Banana). In total, DRC can expect to see the reach of its coastal zone reduced from 50-100 m by 2100. To respond to some of these complex challenges the Department of Environment, Nature Conservation and Tourism, Democratic Republic of Congo implemented the present intervention partnering with the United Nations Development Programme (UNDP) and the Global Environment Facility (GEF).

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.

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)

Climate change has become the day-to-day struggle for this nation - an island nation that faces serious sea-level rise implications should the problem remain uncurbed. The impacts seen are related to rising temperature, sea-level rise (coastal erosion), and changes in rainfall (flooding). To reduce the vulnerability of the population of two regions next to its capital (Victoria), the Ministry of Environment and Energy of Seychelles initiated in 2012 a project aiming at improving the quality of life for the people of Seychelles and restore coastal zones as well as the ecological habitat related to them through nature-based solutions. The project will reduce these vulnerabilities by spearheading ecosystem-based adaptation as climate change risk management—restoring ecosystem functionality, and enhancing ecosystem resilience and sustainable watershed and coastal processes, in order to secure critical water provisioning and flood attenuation.

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).

This intervention was initiated in 2014 in Agege, a slum and a city in itself belonging to Lagos. Agege is one of the 7th most populated low-income communities in Lagos with a total population of around 1,033,064 people. Climate change in Nigeria led to seasonal droughts and floods, causing pressures in terms of food security as well as high temperature and humidity levels which affect directly the economically disadvantaged population in the slums of Lagos. In 2014 a research team at the University of Cardiff alongside community leaders of a Yoruba community in Agege implemented a study on vertical gardens in residential areas with the purpose of alleviating local temperatures and enhancing biodiversity. The implementation started with a study and was continued with the introduction of practical gardens maintained by the local community of 3 residential buildings (one in Suru Street, another in Lagos Street in Agege, and a third in Abeokuta Street).

The Million Trees project was a programme launched by Auckland Mayor Phil Goff in 2017 to plant a million predominantly native trees and shrubs over a period of three years (Ref. 1,2,3,4). It aimed to make Auckland a greener, more beautiful place while creating carbon sinks, protecting the city’s waterways and improving the city’s living environment (Ref. 2,4). The programme engaged a variety of actors in the planting activities, including local boards, iwi, schools, service and social sector groups, private entities, the council group, the New Zealand Transport Association (Ref. 1). Particularly notable partnerships included those with the Department of Corrections and the Trees that Count Trust (Ref. 2,4,6).
The initial goal was met in 2019, and the project has been renewed for 2019-2022 (Ref. 1,7).
