  • Environmental impact: have improved the conservation of 1,300 ha mangrove ecosystem and their biodiversity
  • Governance: have strenghtened the community capacity in managing a Locally Managed Marine Area (LMMA)
  • Women's empowerment: have supported women's involvement in the governance of natural resources - both mangrove and fisheries activities. 
NbS benefits

  • Social inclusion
  • Sustainable development of coastal regions
Lessons learned: 
  • Best time for mangrove replanting should be decided with community members
  • Promoting a voluntary mangrove reforestation is key to ensure that it can be continued without external financial support
  • The dissemination of the results of the monitoring helps the community to understand the state of their resources and the amount of carbon stocks in their mangrove forest
NbS classification
