conservation zones (830 ha), sustainable use zones (1877ha) and restoration zones (1095 ha) to be integrated into the PES schemes. We concluded that thanks to the participatory planning approaches used (participatory mapping and concept modelling workshop), community ownership of the project was strengthened and the chances of a successful mangrove conservation was improved. Regarding the political and legal context, several initiatives in sectoral policies that concern mangroves (environment, fisheries and land use planning) support the implementation of the PES scheme. On the other hand, the inconsistency of the texts concerning the status and the protection of mangroves, the lack of the legal frameworks regarding the implementation of the PES schemes, the lack of coordination between the concerned ministries, the sensitivity of national governance structures to the political context of the country, and the limited governance capacity at the local level are the main obstacles to the implementation of the PES project. These result in lower motivation among the local communities to collaborate in mangrove conservation efforts. Despite these, results from the economic valuation of mangrove ecosystem services showed the Total Economic Value of the mangroves of the bay estimated at 950.23 ha-1year-1 and the Net profit brought by the project is estimated at 6,3745.97 over the 20 years. We concluded that although the Net Profit is not significant, the presence of the PES project of the bay (through the sale of carbon credits) brings additional income to the local communities which will constitute an incentive for the sustainable management of their mangrove forests.
