Global Drought Proportional Economic Loss Risk Deciles

The 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 data set 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).

全球干旱比例经济损失风险十分位数据集系基于2.5分钟网格的干旱灾害经济损失比例，该比例以分析单元的国内生产总值（GDP）为基准。GDP风险估计基于从紧急事件数据库（EM-DAT）的历史记录中得出的区域经济损失率，损失率按灾害的频率和分布进行加权。本数据集遵循Sachs等（2003）的方法论，以确定每个网格单元的GDP基准估计。为更好地反映数据和方法程序周围的置信区间，比例范围被划分为十分位，即大约数量相等的网格单元风险等级的10个类别。该数据集是哥伦比亚大学灾害与风险研究中心（CHRR）、世界银行国际重建与发展银行（世界银行）以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）合作的成果。
