This seminar assesses the impact of severe flooding on household welfare in northern Peru, focusing on the 2017 coastal El Niño floods. Using a novel damage index constructed from remote sensing, weather, and night light datasets, we analyse 5-year data from the Panel Peruvian National Household Survey. The findings show a significant decline in income and expenditure among affected households from 2015 to 2019, leading to increased poverty, particularly in urban areas. Although some recovery is noted post-flood, households depend on donations for consumption. The study recommends developing formal risk-coping strategies such as insurance to enhance resilience against future disaster risks.
