The Coral Triangle Marine Protected Area System aspires to become a region-wide, comprehensive, ecologically representative and well-managed system of marine protected areas (MPAs) and MPA networks. The development of this system will proceed primarily through the implementation of ecological, social, and governance MPA networks at the sub-national scale.

Without effective management, protected areas are unlikely to achieve the high expectations the conservation and development sectors have for them: conserving biodiversity and alleviating poverty. Numerous marine protected area (MPA) assessment initiatives have been developed at various spatial and temporal scales, including the guidebook How is your MPA doing? These management assessments have been useful to sites to clarify and evaluate their objectives, yet efforts to examine broader regional or global patterns in MPA performance are only beginning.

The six Coral Triangle countries—Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands, and Timor-Leste—each have evolving systems of marine protected areas (MPAs) at the national and local levels. More than 1,900 MPAs covering 200,881 km2(1.6% of the exclusive economic zone for the region) have been established within these countries over the last 40 years under legal mandates that range from village level traditional law to national legal frameworks that mandate the protection of large areas as MPAs.

Maintaining ecosystem services of coral reefs, sustainable fishing, and improved food security are the three higher level outcomes of the Coral Triangle Initiative on Coral Reefs, Fisheries and Food Security (CTI-CFF). Food security is an obvious concern of the CTI-CFF because of 130 million people dependent on fish resources for food, income, and livelihoods, and also because it provides 11.3% (19.1 million tons) to global fisheries production from capture fisheries and aquaculture.

The six Coral Triangle countries: Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands, and Timor-Leste, each have evolving systems of marine protected areas (MPAs) at the national and local levels.

Overfishing and habitat destruction due to local and global threats are undermining fisheries, biodiversity, and the long-term sustainability of tropical marine ecosystems worldwide, including in the Coral Triangle. Well-designed and effectively managed marine reserve networks can reduce local threats, and contribute to achieving multiple objectives regarding fisheries management, biodiversity conservation and adaptation to changes in climate and ocean chemistry.
