The solution addresses the degradation of coastal greenbelts by enabling and empowering people to rehabilitate degraded mangrove areas, and protect and manage remaining mangroves which are important for coastal protection, fisheries, and carbon sequestration. Diversifying incomes and providing capacity building for communities ensures sustainability of mangrove rehabilitation, protection and management initiatives.

The solution aims at rehabilitating degraded mangrove areas into coastal greenbelts to protect coasts and people’s livelihoods from climate change associated threats, such as storm surge, erosion, and typhoons. Complementary income diversification initiatives that may also use mangrove ecosystem services encourage and facilitate community participation in mangrove management initiatives.

How do the building blocks interact?

Based on the vulnerability assessment of the communities (Building block 1), the target area for the project intervention is identified. Project implementation starts with capacity building of the community (Building block 2) and the identification and development of income diversification (Building block 3) to enable the community and its individual members to continuously and actively support and manage mangrove protection and conservation. The conservation framework and agreement (Building blocks 4 and 5) help communities and governmental agencies to include mangrove rehabilitation into climate change adaptation and disaster risk reduction plans, to allocate budgets and develop supportive policies, to establish and link to networks, and to jointly formalize an agreement that lays out all details of the partnership and project. Continuous technical and financial support, transparent and good relationships between all partners, including the community, local government and the service provider, are important factors to the success of each building block, and the solution.


The solution helped to protect 300 ha, and to rehabilitate and enrich 150 ha of degraded or sparsely populated mangroves in the target community area, increasing coastal protection and contributing to carbon sequestration and storage. The community actively and continuously supports mangrove rehabilitation, protection and management, which were assisted through the implementation of 7 supplementary livelihoods for active community members. The success of the community initiative gained additional support from other organisations and agencies.


The coastal village, or barangay, of Silonay in Calapan City, Oriental Mindoro has been constantly threatened by storm surges due to its geographic location. Cognizant of this threat, Conservation International Philippines, in collaboration with the local governments of Calapan City and the province of Oriental Mindoro, established the Silonay Mangrove Conservation and Eco-tourism Park, an ecosystem-based adaptation project, which involves mangrove restoration and enrichment to protect village dwellers from climate change-related impacts such as storm surges, rise in sea level and coastal erosion. Additionally, the project aims to empower people in Silonay to actively participate in protection and management of the mangrove park through sustainable livelihoods generated by eco-tourism activities. The Samahang Nagkakaisang Pamayanan ng Silonay (SNPS), a community-based organization, was enabled with the help of the barangay council to manage and protect the mangrove areas. They have completed the rehabilitation and enrichment of a 25-hectare area in the Silonay Mangrove Marine Protected Area. As part of the ecotourism package in Silonay, a 400-meter mangrove boardwalk was also constructed to allow visitors to tour the mangrove area for a fee. Visitors to the mangrove park can engage in close-to-nature activities, such as bird watching, kayak and paddle-boat tours operated by the SNPS. The group is also engaged in the production of snack items such as squash chips and souvenir items such T-shirts and key chains. Visitors are also encouraged to engage in mangrove planting to restore and enrich the wetland ecosystem of Silonay.
