Coastal protection / hazard mitigation

The Bakhawan Eco-Park is a 220-hectare mangrove forest located in Kalibo, Aklan province, Philippines, that started as a reforestation project in 1990. It was a joint project of the local government and a non-government organization, Kalibo Save the Mangroves Association (KASAMA), with the aim of reforesting the muddy shoreline of New Buswang district to protect the community from floods and storm surges [1,2]. Aside from preventing floods, the eco-park also provides locals with livelihood opportunities, mitigates the effects of climate change, and serves as a habitat for various mangrove tree species, birds, and marine life [1,2]. The project's success is largely attributed to the active involvement and support of the local community, with some families playing an integral role in the reforestation program. [2] Notably, the involvement of local women in the NBS initiative has contributed to the success of mangrove conservation. Some women have also taken on the task of policing the mangroves to prevent illegal tree-cutting by trespassers [4]. Today, the eco-park is acknowledged as one of the most successful mangrove reforestation project in the Philippines [1]

18 km southwest of Karachi City (Sandspit area), the World Wildlife Fund Wetland Center (an NGO subsidiary of the WWF) started a project in 2011 called Nurturing Young Sapling with a grant from the Mangrove for the Future organization. The project aimed to increase the mangrove forest cover near Karachi as to restore the ecosystem and improve the habitat for local and migratory birds, crabs and other fauna. In this way, the project sought to improve biodiversity and therefore the availability of livelihood resources to the local community, as well as to enable ecotourism. It also focused to enhance the awareness of school children on the importance of a mangrove ecosystem and advocating for its sustainable use (1).
The project benefited local fishing communities, school children and their families as well as local and international visitors to the Sandspit area. The project resulted in the mangrove plantation at 4.5 hectares area, the establishment of a mangrove (Avicennia Marina) nursery, the plantation of 5000 mangrove saplings, awareness raising of 200 school children, two-day awareness conference, the celebration of significant environmental days at the Wetland Centre to promote conservation awareness among school children (1, 2, 3).
After the successful completion of the project in 2012, WWF Pakistan has been actively involved in the management and plantation of mangroves in the Sandspit area. Multiple campaigns and awareness-raising programs for coastal protection are conducted by WWF in their Sandspit office with multiple partnerships to plant and educate students and communities about the importance of mangrove trees.

The northern part of Thane Creek in Navi Mumbai was declared a 'Protected Area' in 2015 by the Maharashtra Government (1,2,4). As the Central Asian Migratory Flyway (CAMF) ecosystem, it is occupied by a large number of wading birds, especially Lesser Flamingos and Greater Flamingos (1,2). Recently, a Management Plan has been proposed to guide the sustainable management of the 'Thane Creek Flamingo Sanctuary (TCFS)' (1).
The Management Plan (2020-2030), proposed by the Mumbai Mangrove Conservation Unit (MMCU) proposed implementation plans for the conservation of Flamingo species, mangrove management, eco-tourism, education and awareness raising, as well as participatory decision-making (1).
Thane Creek harbours rich biodiversity and spreads over an area of 1690ha (896ha of mangroves and 794ha of adjacent creek water body) (1,2,3). Also, it is located right amidst a mega-city, being crucial to conserving this unique natural environment with its eclectic mix of mangroves, mudflats and threatened bird species (1,2).

As an archipelagic state, Indonesia consists of 18,000 islands and 18,000 km of coastline, which is inhabited by more than 60% of the Indonesian population. Its geographical position exposes the island country to several climate change challenges, ranging from an increase in high temperature to a sea level rise and severe floods. One of the cities affected by flash floods, flooding, and landslides is Pekalongan City, crossed by 7 rivers and home to approx. 300,000 people. Inundations can reach 50-100 cm in many communities, causing distress, evacuations, and severe damage to infrastructure and food security as well as loss of income for the inhabitants that work in the fisheries sector, in the Batik industry (the process of traditionally dyeing fabric, performed on cotton and silk using a resist technique) or in paddy rice farming.

Responding to the climate risks became of utter importance to the municipality of Pekalongan City. To help the Municipal Government of Pekalongan City to overcome the problem caused by climate change, Kemitraan (Partnership for Governance Reform in Indonesia), an implementing and advocacy NGO developed the project on Safekeeping-Surviving-Sustaining towards Resilience, a 3S Approach. The aim was to Build Coastal City Resilience to Climate Change Impacts and Natural Disasters in Pekalongan City, Central Java Province. This was approved on 29 October 2020 and is currently entering its implementation phase. The project will focus on building resilience to climate change impacts with interventions of hard and soft nature. More precisely, the project aims to build capacity and resilience through training, mangrove ecosystem restoration and enhancement of coastal protection, and development of a Local Climate Adaptation Action Plan and implementation of climate-smart actions (1,2). The project aims to reach these goals by employing a collaborative and participatory approach that is locally driven and involves those most at risk. The program is expected to end in April 2023 (1).

In order to prevent the damage to mangrove forests that occurred over the last few decades or more, a project was started in the Penang region aiming to raise public awareness regarding the importance of mangroves for their continued conservation and protection through active community participation (community resilience) (1). The project closely relates to the GEF Focal Area on Biodiversity Conservation operational programme (OP) 2 on Coastal, Marine and Fresh Water Ecosystems and is led by the Penang Inshore Fisherman Welfare Association (PIFWA). The project aimed to regenerate mangrove forests by planting up to 11,000 saplings in order to rehabilitate the once degraded mangroves as they are able to ultimately improve the wetland ecosystem and its biodiversity and thus sustain the livelihood of fisher communities (1).
Mangrove forests are an important part of the Malaysian coastline. Besides their contributions to the biodiversity of the Malaysian coast, mangroves also help greatly with protecting the coastal strip from erosion and providing a means of living for the communities located close to the forests. Stabilising the shoreline and reducing soil erosion, mangroves are also home to myriad species of plants and animals, they provide timber and non-timber forest products, and they support fisheries (1,2). Due to their importance, their disappearance is greatly noticed. From 2000, within a period of 15 years, 25,500 hectares of mangrove forests disappeared, mostly due to industrial-scale logging, clearance for shrimp farming, tourism or firewood (5).

Pirojshanagar Township is an industrial and residential establishment of the company Godrej & Boyce Mfg. Co Ltd (G&B), located in the Vikhroli suburb of Mumbai city along Thane creek, with diverse natural and human-made habitats (1,2). Of the 16 km2 area of the Township, approximately 12 km2 is occupied by the mangrove ecosystem and its associated habitats (1,2). Upon recognizing the importance of this ecosystem, G&B decided to prioritize the conservation of the mangroves that grew along the banks of the newly acquired land (along the Thane Creek west bank) (1,2). Pirojshanagar, with its biodiverse mangrove forest, is sandwiched between two solid waste dumping grounds of the Brihanmumbai Municipal Corporation (BMC), which only increases its importance in the landscape and makes it a green oasis that acts as a carbon sink (1). It was a research-based project and the first successful mangrove conservation project in Mumbai, now serving as the Mumbai Metropolitan's green lung (1,2).

Bangladesh Forest Department (BFD), as a part of its annual development programme, has been leading the coastal afforestation programme to stabilize Bangladesh’s coastline and create green belt. In order to establish mangrove forests in coastal areas, specifically chars in the southern coastal zone, the Forest Department undertook an afforestation project in the new deltas developed in the Bay. Afforestation is being used in vulnerable coastal areas, where the initiative brought mangrove species to the region in order to act as shelters for the exposed coastal communities subject to powerful cyclones, tidal surges, coastal erosion, and other disasters. In terms of the severity of the effects of climate change, Bangladesh is at the forefront, especially for coastal populations, as their livelihoods are wrecked by storms. Nature-based Solutions (NBS) are emerging as significant instruments for coping with climate change, while traditional methods of prevention, such as hard flood defence, have proven to be impractical and unsustainable. Additionally, the project includes greening of the whole coastal regions including creation of strip gardens and home gardens to improve the biodiversity of the area and to stabilize the newly found land. Furthermore, the coastal afforestation project will also help to develop newly accreted land of an island (char) in the Bay of Bengal, which is being included with Bangladesh's mainland from 2021.

"Siargao It Up" is the mangrove conservation programme in Del Carmen, Siargao Islands of the Philippines. The municipality of Del Carmen hosts the largest mangrove forest in the Philippines – consisting of 4,871 hectares as of 2018. This mangrove forest is the habitat of rare and endangered species of flora and fauna both in marine, wetland and terrestrial areas. This ecosystem helps maintain the island's ecological balance by providing rich breeding grounds for aquatic lives. Furthermore, the forest plays a key role in capturing and storing carbon and helps the Philippines to meet its goal of carbon emission reduction. In addition to creating habitats and storing carbon, the forest also protects the community from the inevitable effects of climate change disasters. Recently, in December 2021, it was able to protect the residents from the onslaught of Typhoon Odette. [1, 2, 3]

Mauritania is one of the Sahelian countries most severely affected by the periods of drought occurring since 1968. The resulting desertification is exacerbated by human activities, which have compounded climatic factors, with direct consequences for an already precarious situation. Environmental degradation, responsible for the dangerous displacement of sand dunes in Mauritania, has wiped out homes, livestock and livelihoods throughout the desert country. In Nouakchott, Mauritania’s capital and biggest city, the coast are protected by a fragile wall of dunes at risk from natural erosion, sand mining, grazing of livestock on dune vegetation, and careless abuse of the landscape for leisure like dune racing. In this scenario, protecting the dunes is a priority, and the government is using World Bank financing to overcome the challenge. From a climate change perspective, the intervention addresses accelerating erosion that allows seawater to wash into the city, assaulting buildings, roads, fresh water supply and public space. From a biodiversity perspective, the intervention aims at sustaining the balance between the food for the livelihoods of the local population and the preservation of the rich coastal biodiversity.

Extensive and low-lying, Suriname’s coastal region has been identified as highly vulnerable to climate-induced sea-level rise (Ref. 1). "Momentarily the most endangered community by sea-level rise in the whole of South America and the Caribbean", the Suriname Building With Nature project has seen "wooden, water penetrable dams...being built to trap sediment and replant mangroves" (Ref. 1). Prior to the implementation of the Building With Nature project, no mitigation measures had been undertaken to protect the area, and "human interference ha[d] converted mangrove areas to agricultural land, fishing ponds and settlements", with the loss of stabilisation provided by the mangroves meaning that "the coast has become susceptible to flooding and erosion, losing up to 27 meters of land in one year" (Ref. 1). It has caused "displacement of local habitants and loss of livelihoods, [with]...the local population...and its fisheries, farms, and important religious and cultural sites [being] at risk to frequent flooding and land degradation" (Ref. 1). The Building With Nature approach is touted as being "essential for mangrove and biodiversity conservation and the enhancement of the quantity of the blue carbon sequestered in coastal areas" (Ref. 2).
