This WaSH Sector Alert (July 3, 2025) serves as an early warning and advocacy tool in response to Lebanon’s most severe drought on record, with rainfall over 50% below average and growing pressure on water infrastructure and services. The alert highlights emerging impacts on public health, agriculture, and access to water, while calling attention to urgent preparedness needs. A national Drought Vulnerability Map - based on a Composite Drought Vulnerability Index (DVI) - identifies 274 cadasters as highly or very highly vulnerable, using indicators such as groundwater quality, aquifer resilience, land use, population pressure, and climatic stress. The document outlines priority actions for emergency response and long-term resilience, and calls for $42.2 million in funding to sustain water access and strengthen Lebanon’s climate-resilient WaSH systems.
