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).
This brochure drew significantly from a technical publication by Deda et al. (submitted for publication to Natural Resources Forum), the Millennium Ecosystem Assessment report on Island Systems by Wong et al. 2005, the report of the Ad Hoc Technical Expert Group on Island Biodiversity, which met in Tenerife in 2004 and the draft programme of work on island biodiversity adopted by the Subsidiary Body for Scientifc, Technical and Technological Advice (SBSTTA) at its tenth meeting in 2005
