Question 1

What is the fundamental formula for disaster risk reduction?

Accepted Answer

The fundamental formula for disaster risk reduction is Risk = (Hazard × Vulnerability) / Capacity. This equation shows that risk can be reduced by decreasing vulnerability (susceptibility to damage) and increasing capacity (resources to cope), even when hazards remain unchanged.

Question 2

What are the main differences between qualitative and quantitative risk assessment models?

Accepted Answer

Qualitative models use descriptive scales (low/medium/high) and tools like risk matrices and participatory appraisal, ideal for community-level planning with limited data. Quantitative models use numerical probabilities and tools like probabilistic risk assessment and GIS simulations, used for precision in urban planning and infrastructure projects.

Question 3

How does the Sendai Framework guide disaster risk reduction efforts globally?

Accepted Answer

The Sendai Framework (2015-2030) sets seven global targets and four priorities: understanding risk, strengthening governance, investing in resilience, and enhancing preparedness. It monitors 38 indicators including mortality reduction, economic loss reduction, and critical infrastructure protection.
