Lagoons of New Caledonia
The world’s second largest lagoon and one of the planet’s most biodiverse coral reef systems — the Lagoons of New Caledonia (a French special collectivity in the western Pacific; 24,000 km² of enclosed lagoon; one of the world’s longest barrier reefs at 1,600 km; UNESCO WHS 2008) contain more coral species than the entire Caribbean Sea and support populations of dugong (sea cow), six species of sea turtle, and 1,000 species of fish within their protected waters.

New Caledonia Lagoons (the most precisely NewCal single 24000 km2 lagoon second largest world 1600km barrier reef more coral Caribbean dugong turtle hawksbill UNESCO heritage: New Caledonia is a French special collectivity in the southwestern Pacific Ocean (approximately 1,500 km east of Australia; 2,000 km north of New Zealand); the main island (Grande Terre; 400 km long × 50 km wide) is surrounded by a barrier reef system (the New Caledonian barrier reef — the second longest barrier reef in the world at 1,600 km, after the Australian Great Barrier Reef (2,300 km)); the enclosed lagoon (24,000 km² — approximately the same area as Macedonia; the second largest lagoon in the world after the Great Barrier Reef lagoon) contains extraordinary biodiversity: 1,000+ fish species (the same or greater diversity as the entire Red Sea); more coral genera (74 genera) than the entire Caribbean Sea (where approximately 20 genera are found); populations of dugong (Dugong dugon — the “sea cow”; New Caledonia has one of the last significant populations of dugong in the Pacific; approximately 2,000-3,000 animals; the animals graze on seagrass meadows in the shallow lagoon); six species of sea turtle (including the hawksbill, loggerhead, leatherback, and green sea turtle); numerous shark species; humpback whales (calving in the lagoon July-September) — the most precisely NewCal single 24000 km2 lagoon second largest world 1600km barrier reef more coral Caribbean dugong turtle hawksbill UNESCO heritage in any UNESCO world heritage site)).
Key facts
- Kanak Indigenous Heritage: the most precisely NewCal single Kanak indigenous Melanesian population clans chiefdoms sacred reefs fishing territory taboo traditional knowledge UNESCO heritage — the Kanak people (the indigenous Melanesian population of New Caledonia; approximately 40% of New Caledonia’s 270,000 inhabitants; the Kanak arrived in New Caledonia approximately 3,000 years ago from the Melanesian archipelagos to the northwest; the Kanak language group (approximately 30 distinct languages); the Kanak social structure (clan-based with hereditary chiefs; the sacred reefs (the marine areas designated as sacred and taboo by Kanak clan authority) were an early form of marine protected area — fishing was prohibited in sacred reef areas, protecting the reef ecology; the integration of Kanak traditional knowledge into the management of the UNESCO site was a condition of the French government’s UNESCO nomination)
- The Nickel Question: the most precisely NewCal single nickel mining 25% world reserves laterite ore pollution runoff reef sedimentation independence referendum UNESCO threat heritage — the conflict between nickel mining and reef conservation: New Caledonia has approximately 25% of the world’s known nickel reserves (the laterite ore deposits of the Grande Terre massif; the red soil of the hillsides is the visible surface expression of the nickel ore); nickel mining is the dominant industry of New Caledonia (the main source of government revenue; the basis of the French government’s political interest in retaining the territory); the problem: nickel mining produces red laterite runoff that flows into rivers and reaches the lagoon; the sedimentation of the lagoon reef (the fine red laterite particles smother the coral) is the main long-term threat to the UNESCO site; the balance between nickel revenue and reef conservation is the central environmental political debate in New Caledonia
