The Coral Triangle initiative: on coral reefs, fisheries and food security

Scientists have identified an area called the Coral Triangle within the Indo-Pacific - its boundaries defined by marine zones containing 500 or more species of reef-building coral. This region covers all or part of six countries: Indonesia (Central and Eastern), Malaysia (Sabah), Papua New Guinea, Philippines,

Solomon Islands and Timor-Leste. Certain neighboring countries – including Australia, Fiji, New Caledonia and Vanuatu - contain rich coral biodiversity, but with somewhat lower numbers.
