Global Drought Proportional Economic Loss Risk Deciles is a 2.5 minute grid of drought hazard economic loss as proportions
of Gross Domestic Product
(GDP) per analytical unit. Estimates of GDP at risk are based on regional economic loss rates derived from historical records
of the Emergency Events Database (EM-DAT). Loss rates are
weighted by the hazard's frequency and distribution. The methodology of Sachs et al. (2003) is followed to determine baseline
estimates of GDP per grid cell. To better reflect the
confidence surrounding the data and procedures, the range of proportionalities is classified into deciles, 10 class of an
approximately equal number of grid cells of increasing risk. This
dataset is the result of collaboration among the Columbia University Center for Hazards and Risk Research (CHRR), International
Bank for Reconstruction and Development/The World Bank, and
Columbia University Center for International Earth Science Information Network (CIESIN).
To provide a spatial surface of the proportional economic impacts of global drought hazard.
