Description:
Abstract:
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.
Purpose:
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.
Supplemental_Information:
The threat indicators gauge current and potential risks associated with human activities. A strength of the analysis lies in its use of regionally consistent data sets to develop regionally consistent indicators of human pressure on coral reefs. However, the model is not perfect, and omissions and other errors in the data sets are inevitable.

Process_Description:
Watershed-based analysis links land-based sources of threat with point of discharge to the sea. Analysis of sediment and pollution threat to coral reefs implemented for more than 3,000 watersheds discharging to the Caribbean. Relative erosion rates estimated across the landscape, based on slope, land cover type, precipitation (during the month of maximum rainfall), and soiltype. Erosion rates summarized by watershed (adjusting for watershed size) to estimate resulting sediment delivery at river mouths. Sediment plume dispersion estimated using a function in which sediment diminishes as distance from the river mouth increases.
