Summary
The report 'Reefs at Risk' assesses the global status of coral reefs, finding that 58% are potentially threatened by human activities. It identifies overexploitation and coastal development as the primary drivers of risk, with Southeast Asia being the most threatened region. The study utilizes a map-based indicator to flag high-risk areas, particularly biodiversity hot spots, and evaluates the current state of marine protected areas (MPAs).
Key insights
- Approximately 58% of the world's coral reefs are potentially threatened by human activity, with 27% classified as high risk and 31% as medium risk.
- Overexploitation of marine resources and coastal development are the most significant threats, each affecting roughly one-third of all reefs globally.
- Southeast Asia is the most threatened region globally, with over 80% of its reefs at risk and more than half (56%) facing high potential threat.
- The Pacific region contains the largest area of coral reefs and is the least threatened, with approximately 60% of its reefs classified as low risk.
- At least 11% of global coral reefs are 'biodiversity hot spots,' defined as areas with high reef fish species richness that are also under high threat; these are concentrated in Southeast Asia and the Caribbean.
- Marine protected areas (MPAs) are insufficient in scale and coverage; at least 40 countries have no formal protection for their reefs, and most existing MPAs are smaller than one square kilometer.
- Destructive fishing practices, specifically the use of cyanide to capture live fish for the aquarium and restaurant trades, are widespread across the Indo-Pacific region.
