This approach note lays out the methodology for developing a Model District DRR Strategy and a Minimum Readiness Checklist for Haryana, a state facing a complex multi-hazard profile spanning riverine floods, heatwaves, seismic risk, and industrial-chemical hazards. A baseline review of all 23 District Disaster Management Plans finds that only three are recently updated, seven are unavailable publicly, and most lack localised GIS-based hazard and vulnerability assessments. The proposed framework rests on four pillars: data-driven risk assessment, hazard-specific contextualisation, community-based DRR with gender and social inclusion, and technological modernisation of early warning. It draws transferable lessons from five Pan-India models — Odisha's shelter network, Ahmedabad's Heat Action Plan, Mumbai's iFLOWS, Gujarat's Chemical Disaster Plan, and Kerala's panchayat-level DM integration. A responsibility matrix maps each action to nodal departments, and a phased roadmap moves through SDMA coordination to pilot district selection in Gurugram, Panipat, and Hisar/Sirsa by September 2026.
