Governance and implementation challenges for mangrove forest Payments for Ecosystem Services (PES): Empirical evidence from the Philippines

Abstract Mangrove forests have been considered as potentially suitable for PES, though few mangrove PES schemes exist worldwide, suggesting they - and the broader social-ecological and governance systems in which they sit - may not be as conducive to PES as first thought. This study assesses economic, social, and governance challenges to implementing PES in mangroves. It draws on empirical evidence from two prospective community-level mangrove carbon PES schemes in the Philippines, where fishing and aquaculture are major livelihoods. We conducted (1) policy reviews and interviews with local communities, government, and NGOs to investigate governability; (2) village income accounting to determine the extra income that participants could receive through PES; and (3) a choice ranking exercise to elicit preferences on how payments could best be spent to enhance participant wellbeing. The latter approach identifies key gender differences, and enables potential PES-induced social-ecological trade-offs to be pre-empted. Blue carbon PES can contribute an additional 2.3–5.8% of current village incomes, while villagers would prefer to spend the monies on more effective fishing equipment, which could perversely jeopardize fishery sustainability. To be most successful, coastal PES schemes in the Philippines need to be managed through a multi-level governance regime involving co-management and local participation.
