This policy brief presents findings from the Bangladesh case study under the Early Warning and early Action for Cascading risks to food security (EWAC) project. Food security in climate-vulnerable districts like Satkhira, Rangpur, and Faridpur in Bangladesh is increasingly threatened by disasters that disrupt crop production, markets, water quality, and diets. The brief highlights the need for people-centred, multi-hazard early warning systems aligned with food security dimensions (availability, access, utilization, and stability) plus inter-agency collaboration and community empowerment can strengthen resilience and reduce long-term humanitarian impacts in Bangladesh.
