Description:

Abstract:

The relative erosion rate by land cover type for 1 km grid cells derived for all land draining into the Caribbean Sea and Gulf of Mexico. Uses a using a modified, simplified form of the Revised Universal Soil Loss Equation (RUSLE).

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. 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 and pollution from inland sources were modeled for over 3,000 watersheds discharging into the Caribbean.

Process_Description:

The Global Land Cover Characteristics Database (USGS / Loveland, 2000) using International Geosphere-Biosphere Program land cover categories was reclassified to relative erosion rates, ranging from 15 (for forest) to 200 for croplands (see below). (1000 m resolution) These relative erosion rates are based on published work involving conversion factors. (Berner, E. and Berner R. 1987. The Global Water Cycle: Geochemistry and Environment, pp. 183-189. Yale University, Prentice-Hall International and Nyborg, Petter A. 1995. Assessment of Soil Erosion in Sierra Leone. The World Bank, Washington).

GLCC_CODE --- LAND COVER CATEGORY --- RELATIVE EROSION RATE; 19 --- Water bodies --- 5; 1-5 --- Forest (All types of closed forest) --- 15; 6 --- Closed shrub land --- 45; 7 --- Open shrub land --- 50; 8 --- Woody savanna --- 60; 11 --- Permanent wetlands --- 80; 9 --- Savannas --- 100; 14 --- Cropland/natural --- 120; 10 --- Grasslands --- 125; 12 --- Croplands --- 200; 13 --- Urban and built-up --- 210; 16 --- Barren or sparse vegetation --- 220
