Improving coastal resource management and coral reef protection by providing comprehensive information on threats to coral reefs, the value of goods and services provided by these ecosystems, and economic losses that will result from their degradation.
Many people in coastal communities throughout Latin America and the Caribbean depend on the natural resources provided by reefs for their livelihoods. Ensuring proper management of the reefs is vital for the economic and environmental health of the region, but there is a lack of quality information about the relationship between human activities and coral reef condition across the region. The Reefs at Risk in the Caribbean project was a response to this information need. The primary goal of the project was to raise awareness and improve management of coral reefs across the region through improving the knowledge base on the status of and threats to coral reefs. In collaboration with partner institutions across the region, we implemented an analysis to link human activities with reef condition. A major component of the project involved modeling (estimating) threat to coral reefs from human activities.

Both download options provide estimates of threat to coral reefs for the four individual threats (coastal development, marine-based threats, overfishing, and sediment and pollution from upland sources), in addition to integrated threat – the Reefs at Risk threat index.
Vector Data Sets including data on coral reef locations, estimated threat to coral reefs from human activities, watersheds boundaries, and marine protected areas, all in ESRI ArcView shapefile format in Geographic projection.
This option five polygon data sets reflecting estimated threats from human activities; five point data sets reflecting coral reef locations by these estimated threats; a polygon data set of watershed boundaries (with associated erosion estimates); a point data set reflecting river mouths and estimated relative sediment delivery; a polygon data set reflecting country boundaries; a line data set reflecting the coastline; and a point data set reflecting cruise ship ports of call. The zip file also includes an ArcView project file (rrcar_vec.apr) which requires ESRI’s ArcView software.
GRID Data Sets including data on coral reef locations, estimated threat to coral reefs from human activities, relative erosion rates across the landscape, and bathymetry, all in ESRI ArcView GRID format in Lambert Equal-Area Azimuthal projection.
This option five GRID data sets reflecting estimated threat to coral reefs from human activities; five GRID data sets reflecting coral reef locations classified by estimated threat; a GRID data set reflecting estimated relative erosion rates across the landscape; and a GRID reflecting Bathymetry. All GRIDs are in Lambert Equal-Area Azimuthal projection.
In addition, the zip file includes several vector shapefiles in Geographic projection – polygon watershed boundaries (with associated erosion estimates), polygon country boundaries, and a point data set reflecting river mouths and estimated relative sediment delivery. The zip file also includes an ArcView project file (rrcar_gr.apr) which requires ESRI’s ArcView software and Spatial Analyst 2.0 extension.
Reefs at Risk in the Caribbean data are available through two online GIS services:
ReefBase. Reefs at Risk results from the global (1998), Southeast Asia (2002) and Caribbean (2004) analyses are available from ReefBase’s online GIS. This site displays Reefs at Risk threat analysis results along with a range of other reef-related data sets and satellite images.
Caribbean Reefs at Risk. A web site focused on threats to Caribbean coral reefs has been developed through a partnership of the World Resources Institute (WRI), The University of the West Indies Caribbean Coastal Data Center (UWI-CDC), International Coral Reef Action Network (ICRAN), United Nations Environment Programme, Caribbean Environment Programme (UNEP-CEP), and the United States Geological Survey - National Biological Information Infrastructure (NBII). The site provides base data on the Caribbean basin, watersheds, and land-based threats to coral reefs, highlighting the results of the Reefs at Risk in the Caribbean analysis. The site provides mapping using online GIS, as well as data for download accompanied by metadata.
