Disaster risk reduction (DRR) involves a systematic approach to identifying, assessing, and reducing the risks of disasters through minimizing vulnerabilities and exposure while enhancing preparedness and resilience. One of the primary strategies for disaster risk reduction is comprehensive risk assessment and hazard mapping. This involves identifying potential natural and human-induced hazards, analyzing their probability and potential impact, and mapping vulnerable populations, infrastructure, and critical facilities. Scientific tools such as Geographic Information Systems (GIS), remote sensing, and predictive modeling are widely used to generate accurate risk profiles. These assessments form the foundation for informed decision-making and planning. Another important strategy is vulnerability reduction through structural and non-structural measures. Structural measures include the construction of disaster-resistant infrastructure such as earthquake-resistant buildings, cyclone shelters, flood embankments, stormwater drainage systems, and retaining walls in landslide-prone areas. Enforcement of building codes and land-use regulations plays
