Marine Protected Areas (MPAs) are essential for conserving marine biodiversity, yet many need more effective compliance and enforcement due to insufficient economic resources. The Blue Natural Capital Financing Facility (BNCFF) addresses this challenge by supporting the Blue Alliance—a partnership of local NGOs, communities, and Blue Finance—in managing over 5,200 hectares of MPAs in Oriental Mindoro, Philippines. This initiative leverages sustainable tourism to generate revenue for conservation and community development.
