Global Landslide Total Economic Loss Risk DecilesEntry ID: CIESIN_CHRR_NDH_LSLIDE_TELRD
Abstract: Global Landslide Total Economic Loss Risk Deciles is a 2.5 minute grid of global landslide total
economic loss risks. A process of spatially allocating Gross Domestic Product (GDP) based upon the Sachs et al. (2003) methodology is
utilized. First the proportional contributions of subnational units to their respective national GDP are determined using sources of
various origins. The ... contribution rates are then applied to published World Bank Development Indicators to determine a GDP value for
the subnational unit. Once the national GDP has been spatially stratified into the smallest administrative units available, GDP
values for grid cells are derived using Gridded Population of the World, Version 3 (GPWv3) data of population distributions. A per
capita contribution value is determined within each subnational unit, and this value is multiplied by the population per grid cell.
Once a GDP value has been determined on a per grid cell basis, then the regionally variable loss rate as derived from the historical
records of EM-DAT is used to determine the total economic loss risks posed to a grid cell by landslide hazards. The final surface
does not present absolute values of total economic loss, but rather a relative decile (1-10 with increasing risk) ranking of grid
cells based upon the calculated economic loss risks. 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).
Purpose: To provide insight into the relative frequency, distribution, and potential impact of global
earthquake hazard events in relation to subnational distributions of GDP.
