INTRODUCTION: Natural disasters disrupt people's lives, bringing about serious economic and social losses. Disaster risk management is a set of measures, including planning, decision-making, accountability, and operational activities at all levels. Moreover, it is of considerable significance to take advantage of social capacities and community participation before, during, and after disasters. The present study aimed to explain the prerequisites of community-based disaster risk management in Iran in 2020.
METHODS: This data-driven qualitative study was conducted using Strauss and Corbin's systematic approach. The statistical population included all disaster management experts
 and non-governmental organizations in universities, the National Disaster Management Organization, the provincial disaster management departments, and senior managers of the Red Crescent Society. Out of this population, 22 subjects were purposefully selected via snowball sampling taking into account the geographical, climatic, cultural, social, and religious diversity of different regions of the country. The data were collected via semi-structured interviews and analysed using open coding, axial coding, and selective coding.
FINDINGS: Based on the obtained results, the prerequisites of community-based disaster risk  management include: "legal obligation", "public sensitization", "strategic planning", "public participation", "social capacity building", " building cohesion and empathy ", "action (prevention, preparedness, needs assessment, planning, and response", "formation and development of expert teams", "logistics forecasting and equipment", "preparation", and attention to geographical conditions".
CONCLUSION: As evidenced by the obtained results, the required measures for the successful implementation of community-based disaster risk management can be assigned to two categories: The first one encompasses the measures that require structural changes and law reform and are taken at the national level and National Disaster Management Organization of the country. The second type of measure must be implemented at the local and operational management levels.
