This dataset depicts relative erosion rate derived for all land draining above the Mesoamerican reef. It is a function of slope, land cover type, precipitation and soil type. The indicators developed by the Reefs at Risk in the Caribbean project enable detailed comparative analyses of threats on many scales. The Reefs at Risk indicators are a simplification of human activities and complex natural processes. This data set was derived at the World Resources Institute for input to the sedimentation and pollution from watershed based sources threat analysis. Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation...

Using basins derived from a hydrologically-corrected 30m resolution DEM as a unit for summary statistics, we provide a series of indicators focused on land-based sources of threat within the US Virgin Islands and Puerto Rico. This includes indicators of a) the relative vulnerability of the land to erosion (based on slope, precipitation and soil erodibility); b) the relative erosion potential (REP) of the land, based on the relative vulnerability of the land, coupled with the current land cover type; c) the sediment delivery rate for each basin (percentage of eroded which reaches the river mouth); d) estimated sediment delivery for the basin, given current land use;

To capture cumulative threat in a given location, the four threats in the Reefs at Risk Caribbean analysis - coastal development, marine-based, sedimentation and overfishing - were integrated into a single index - the Reefs at Risk Threat Index.

Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation and pollution from inland sources were modeled for over 3,000 watersheds discharging into the Caribbean.

Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. Threats from sedimentation and pollution from inland sources were modeled for about 150 watersheds discharging along the Mesoamerican reef, and associated sediment plumes estimated.

To capture cumulative threat in a given location, the four threats in the Reefs at Risk Caribbean analysis - coastal development, marine-based, sedimentation and overfishing - were integrated into a single index - the Reefs at Risk Threat Index. A 100 m resolution GRID reflecting coral reef locations was classifed by this threat index, which was then converted to points for display.
This dataset depicts combined threats to coral reefs in the Mesoamerican region based on coastal development, marine-based, sedimentation and overfishing as polygons.
Threats to coral reefs from marine-based sources evaluated based on distance to ports, stratified by size; intensity of cruise ship visitation; and distance to oil and gas infrastructure, processing, and pipelines.
This dataset shows threats from coastal development estimated based on distance from cities, ports, airports, and dive tourism centers, as well as population density, population growth, and tourism growth in the area. For areas inside Marine Protected Areas (MPAs), management effectiveness was included as a mitigating threat.
Using mapped watersheds as a unit for summary statistics, we provide a series of indicators focused on land-based sources of threat within the US Virgin Islands. This includes indicators of a) the relative vulnerability of the land to erosion (based on slope, precipitation and soil erodibility); b) the relative erosion potential (REP) of the land, based on the relative vulnerability of the land, coupled with the current land cover type; c) the sediment delivery rate for each basin (percentage of eroded which reaches the river mouth); d) estimated sediment delivery for the basin, given current land use; e) the road density within the basin, and f) indictors of how erosion prone areas with roads might be (average...

Threats to coral reefs from fishing pressure evaluated based on coastal population density and shelf area (up to 30 m depth) within 30 km of reef. Analysis calibrated using survey observations of coral reef fish abundance. Management effectiveness included as mitigating factor for threats to reefs inside marine protected areas (MPAs).
