Global Landslide Total Economic Loss Risk Deciles

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.
