Coral Reef Threats - Reefs at Risk

Date created: 07 March 2022

Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).

Like the original Reefs at Risk, this study evaluates threats to coral reefs from a wide range of human activities. For the first time, it also includes an assessment of climate-related threats to reefs. In addition, Reefs at Risk Revisited includes a global assessment of the vulnerability of nations and territories to coral reef degradation, based on their dependence on coral reefs and their capacity to adapt.

WRI led the Reefs at Risk Revisited analysis in collaboration with a broad partnership of more than 25 research, conservation, and educational organizations. Partners have provided data, offered guidance on the analytical approach, contributed to the report, and served as critical reviewers of the maps and findings.

Reefs at Risk Revisited is a project of the World Resources Institute (WRI), developed and implemented in close collaboration with: The Nature Conservancy (TNC) WorldFish Center International Coral Reef Action Network (ICRAN) United Nations Environment Programme - World Conservation Monitoring Centre (UNEP-WCMC) Global Coral Reef Monitoring Network (GCRMN)
