Lebanon remains highly vulnerable to waterborne diseases such as cholera, hepatitis A, and rotavirus due to deteriorating WaSH conditions, displacement, and severe drought. Building on the successful 2022 Cholera Risk Map, the 2025 WBD Risk Map integrates the Drought Vulnerability Index with population, water access, surveillance, and sanitation indicators to provide a forward-looking early warning tool. The model identifies 85 highly vulnerable cadastres and shows how drought-driven water scarcity, infrastructure damage, and population pressures increase disease risk. Strategic priorities include institutionalizing early warning, ensuring safe water during drought, targeting high-risk populations, and mobilizing resources for preparedness. The map serves both as a technical and advocacy tool by guiding interventions, resource allocation, and donor investment. By enabling anticipatory action, it shifts Lebanon from reactive outbreak response to proactive prevention, reducing health risks and saving costs in
