World's Coral Reefs Under Threat

"Reefs at Risk Revisited," the most detailed assessment of threats to coral reefs ever undertaken, is being released by the World Resources Institute, along with the Nature Conservancy, the WorldFish Center, the International Coral Reef Action Network, Global Coral Reef Monitoring Network, and the UNEP-World Conservation Monitoring Center, along with a network of more than 25 organisations. Launch activities are taking place in Washington, DC, London, UK, Malaysia, Indonesia, the Caribbean, Australia, and other locations around the world.

"This report serves as a wake-up call for policy-makers, business leaders, ocean managers, and others about the urgent need for greater protection for coral reefs," said Dr. Jane Lubchenco, under secretary of commerce for oceans and atmosphere and NOAA administrator. "As the report makes clear, local and global threats, including climate change, are already having significant impacts on coral reefs, putting the future of these beautiful and valuable ecosystems at risk."
Local pressures, especially overfishing and destructive fishing, are causing many reefs to be degraded. Global pressures are leading to coral bleaching from rising sea temperatures and increasing ocean acidification from carbon dioxide pollution. According to the new analysis, if left unchecked, more than 90% of reefs will be threatened by 2030 and nearly all reefs will be at risk by 2050.

The report includes multiple recommendations to better protect and manage reefs, including through marine protected areas. The analysis shows that more than one-quarter of reefs are already encompassed in a range of parks and reserves, more than any other marine habitat. However, only six percent of reefs are in protected areas that are effectively managed.
"Well managed marine protected areas are one of the best tools to safeguard reefs," said Mark Spalding, senior marine scientist at the Nature Conservancy and a lead author of the report. "At their core, reefs are about people as well as nature: ensuring stable food supplies, promoting recovery from coral bleaching, and acting as a magnet for tourist dollars. We need apply the knowledge we have to shore up existing protected areas, as well as to designate new sites where threats are highest, such as the populous hearts of the Caribbean, Southeast Asia, East Africa and the Middle East."

Reefs offer multiple benefits to people and the economy - providing food, sustaining livelihoods, supporting tourism, protecting coasts, and even helping to prevent disease. According the report, more than 275 million people live in the direct vicinity (30 km/18 miles) of coral reefs. In more than 100 countries and territories, coral reefs protect 150,000 km (over 93,000 miles) of shorelines, helping defend coastal communities and infrastructure against storms and erosion.
For the first time, the report identifies the 27 nations most socially and economically vulnerable to coral reef degradation and loss. Among these, the nine most vulnerable countries are: Haiti, Grenada, Philippines, Comoros, Vanuatu, Tanzania, Kiribati, Fiji, and Indonesia.

The report is an update of "Reefs at Risk," released by WRI in 1998, which served as an important resource for policymakers to understand and address the threats of reefs. The new report uses the latest data and satellite information to map coral reefs, including a reef map with a resolution 64 times higher than the original report.
