Blue Ventures is employing a participatory monitoring and management approach as a solution to address degradation and deforestation of mangroves in Bay of Assassins, in the south of the Velondriake Locally Managed Marine Area (LMMA). This approach uses the generation of carbon credits, which can in turn generate sustainable financing to both residents of the Bay of Assassin and the Velondriake Management committee.

Andavadoaka, Madagascar


Although a critical habitat for threatened marine biodiversity and a vital source of food and income for millions of coastal Madagasy people, Madagascar’s mangrove forests, and the fisheries they support, are at risk. Widespread degradation and deforestation of mangroves are caused by the overexploitation of wood resources for construction and commercial use (e.g. lime production, charcoal and timber).


Coastal community and mangrove dependent community.

How do the building blocks interact?

The full engagement of communities in the management of natural resources (BB1-4) enhances social integration of the resource managers, and co-operation between local communities and other stakeholders. This can solve many of the sustainability problems posed by external and hierarchical management. When the community has a better understanding of the natural resource health and impacts of anthropogenic activities, they can establish effective natural resource management and implement management strategies for sustainable use of resources. Promotion of the voluntary work for mangrove reforestation (BB5), along with education in why this is important at the start-up stage, and the carbon revenue from the sale of the carbon credits can be used for the long term project activities (carbon monitoring, replanting, law enforcement). BB1-5 are in themselves building blocks for a carbon project (BB6). This last building block both helps to fund the management that is integral to the LMMA and in the first place incentivizes this management.


  • Participatory mangrove zoning has placed 830 ha under strict protection against mangrove logging to enhance carbon stocks.
  • 1877 ha of mangrove are harvested by the community under a controlled harvesting regime.
  • 1095 ha of mangrove are designated for replantation by community groups in the project area. Community groups (seaweed farmers, youth club, school children, and women’s association) have replanted 12 ha of degraded mangrove to date.
