Global Landslide Proportional Economic Loss Risk Deciles

The Global Landslide Proportional Economic Loss Risk Deciles is a 2.5 minute grid of landslide 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).

全球滑坡比例经济损失风险十位数数据集系基于2.5分钟网格的滑坡灾害经济损失比例，该比例以分析单元的国内生产总值（GDP）表示。GDP风险估计基于历史应急事件数据库（EM-DAT）中得出的区域经济损失率。损失率根据灾害的频率和分布进行加权。本数据集遵循Sachs等（2003）的方法，以确定网格单元的GDP基线估计值。为更好地反映数据与流程的置信度，比例范围被划分为十位数，即约等数量的网格单元，其风险等级依次增加。该数据集系哥伦比亚大学灾害与风险研究中心（CHRR）、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）之间的合作成果。
