The document discusses sustainable financing for marine protected areas (MPAs). It notes several pressures threatening marine ecosystems and biodiversity. MPAs can help address these pressures but require stable long-term financing. Current MPA financing comes from domestic government budgets, external development aid, trust funds, user fees, taxes, subsidies, and payments for ecosystem services in some areas. Effective MPA financing requires understanding costs and benefits, siting MPAs optimally, including financing strategies in management plans, robust monitoring, and compliance. The EU provides funding to MPAs in Mauritania and Guinea-Bissau through fisheries agreements, though political support fluctuates.
