Abstract: Chad is consistently rated among the most vulnerable countries in the world to climate change. Increasing temperatures and precipitation are raising the threat of drought, flood, heatwaves, and vector-borne diseases. Infrastructure limitations and Chad's young, poor, and rapidly growing population amplify these vulnerabilities. Flood risk, in particular, is becoming increasingly salient in Chad due to a series of devastating floods in recent years, notably in 2012, 2022, and 2024. This report analyzes flood risk in Chad as well as flooding incidence over the past 10-15 years using multiple data sources, to assess current and projected exposure to flooding and identify areas with significant risk. The findings aim to inform flood response strategies through the national safety net program and support broader efforts to strengthen resilience.
