This report presents the results of a rapid geospatial flood impact assessment conducted by FAO in October 2023, in response to the catastrophic floods that struck eastern Libya in September. Triggered by extreme rainfall and dam collapses, the disaster caused severe human and economic losses, with Derna and surrounding districts heavily impacted. The assessment used satellite imagery and geospatial technologies to evaluate six key indicators: flood extent, land cover changes, irrigated cropland exposure, population and farmer vulnerability, and annual water bodies. It provides visual maps and statistical data at the district level to support emergency relief and post-disaster planning. The findings show Benghazi as the most affected area, with 36,245 ha flooded. The report also outlines a sampling strategy for field data collection. It emphasizes the importance of tailored land cover updates and field campaigns. Ultimately, the report aims to inform recovery strategies and strengthen future agricultural and disaster preparedness programmes in Libya.
