The assessment covers areas south of the Litani River, including Bent Jbeil, Marjaayoun, El Nabatieh, Tyre, and Saida, and follows the recent release for Beirut and Mount Lebanon.

The assessment used a Geospatial Artificial Intelligence (GeoAI) workflow*, complemented by office-based visual validation only and is not complemented by a ground-truthing exercise. High-resolution satellite imagery from 29 April 2026 was compared with a baseline from 23 October 2025, allowing identification of visible conflict related damage such as roof collapse, structural deformation, and debris accumulation at the building-footprint level. Debris volumes and damage costs were calculated using building footprints, floor counts, and standardized replacement costs, consistent with UNDP methodology and previous assessments.
