Reefs at risk : a map-based indicator of threats to the world's coral reefs

Reefs at Risk Revisited is part of a series that began in 1998 with the release of the first global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Two regionspecific publications followed with Reefs at Risk in Southeast Asia (2002) and Reefs at Risk in the Caribbean (2004). These regional studies incorporated more detailed data and refined the modeling approach for mapping the impact of human activities on reefs. Reefs at Risk Revisited—an updated, enhanced global report—has drawn upon the improved methodology of the regional studies, more detailed global data sets, and new developments in mapping technology and coral reef science. The Reefs at Risk Revisited project was a multi-year, collaborative effort that involved more than 25 partner institutions. The project has compiled far more data, maps, and statistics than can be presented in this report. This additional information is available at www.wri.org/reefs.
