Summary
Abstract: 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).

The data in American Standard Code for Information Interchange (ASCII) format and a map in Portable Document Format (PDF) and Portable Network Graphics (PNG) are available from the NASA Socioeconomic Data and Applications Center (SEDAC).


Purpose: To provide a spatial surface of the proportional economic impacts of global drought hazard.

Quality
Building upon a methodology pioneered by Sachs et al. (2003), a Gross Domestic Product (GDP) value (US$, 2000, purchase power parity adjusted (PPP)) is estimated for each grid cell. The process begins by determining the contribution of each subnational unit to national GDP using data of varied origin. The ratio of the subnational production estimate to the national GDP is the contribution ratio. To ensure uniformity, these contribution ratios are utilized with published World Bank estimates of GDP. Once a standardized value of subnational GDP has been calculated, this value is further subdivided by the total population within the subnational unit as determined using Gridded Population of the World, Version 3 (GPWv3) data. This subnational, per-person GDP value is multiplied by the population density per grid cell to estimate the GDP value on a per grid cell basis.

Regional loss rates were derived from the Emergency Events Database (EM-DAT) records, providing estimates of the hazard's impact. Combining the impact data with the frequency and distribution data of the Global Drought Hazard Frequency and Distribution dataset and the baseline productivity data provided by the spatially allocated GDP estimates resulted in crude estimates of the GDP at risk. In turn, these estimates are transformed into proportions of the original GDP estimates of the grid cells on a per grid cell basis. In order to more accurately reflect the confidence surrounding the proportionalities, they are further classified into deciles, 10 classes of approximately an equal number of grid cells.

Note that areas of &No Data& are not necessarily without risk from hazards, but may rather be an artifact of a mask that excluded from analysis those areas with a population density below five persons per square kilometer and without significant agriculture.
