Satellites, Self-reports, and Submersion: Exposure to Floods in Bangladesh
开发了孟加拉国洪水暴露的客观数据，发现降雨和自我报告数据无法准确反映真实洪水暴露，并利用这些数据研究适应行为，对评估气候变化影响有重要价值。
A burgeoning “Climate-Economy” literature has uncovered many effects of changes in temperature and precipitation on economic activity, but has made considerably less progress in modeling the effects of other associated phenomena, like natural disasters. We develop new, objective data on floods, focusing on Bangladesh. We show that rainfall and self-reported exposure are weak proxies for true flood exposure. These data allow us to study adaptation, giving accurate measures of both long-term averages and short term variation in exposure. This is important in studying climate change impacts, as people will not only experience new exposures, but also experience them differently.
