Jawaharlal Nehru Technological University Hyderabad B.Tech III DISASTER PREPAREDNESS AND PLANNING MANAGEMENT Previous Question Paper (August - 2022 - R18)

A disaster is a serious disruption of the functioning of a community or society at any scale due to hazardous events interacting with conditions of exposure, vulnerability, and capacity, leading to widespread human, material, economic, or environmental losses that exceed the ability of the affected community to cope using its own resources.

Disaster preparedness involves a continuous cycle of planning, organizing, training, equipping, and exercising to ensure effective coordination and response. Key approaches include:

• Community-Based Preparedness: Empowering local populations through awareness programs, drills, and training to act as first responders.
• Institutional and Policy Frameworks: Establishing clear legal mandates, disaster management authorities, and standard operating procedures (SOPs) at national and regional levels.
• Early Warning Systems: Implementing technical infrastructure to detect hazards early and disseminate timely alerts to vulnerable populations.
• Resource Mobilization: Pre-positioning emergency supplies, medical kits, and communication equipment to ensure rapid deployment during crises.

Disaster mitigation refers to structural and non-structural measures undertaken to limit the adverse impact of natural hazards and environmental disasters. The primary methods are:

• Structural Mitigation: Involves physical construction or engineering interventions. Examples include building earthquake-resistant structures, constructing dams and levees for flood control, and retrofitting existing infrastructure to withstand high winds or seismic activity.
• Non-Structural Mitigation: Focuses on policies, regulations, and social awareness. This includes land-use planning to restrict development in high-risk zones, enforcing strict building codes, and implementing insurance schemes to distribute financial risk.
• Environmental Management: Protecting natural ecosystems such as mangroves, forests, and wetlands which act as natural buffers against tsunamis, landslides, and floods.
• Public Awareness and Education: Conducting training programs and public education campaigns to reduce vulnerability by changing behavior and improving community resilience.
