CONCEPTUAL FRAMEWORK FOR DISASTER/CLIMATE RISK
MANAGEMENT
AVOIDING DISASTERS
Based on weather forecasts and near-real time information
Based on awareness of hazards, education indivuals and access to accurate hazard maps

STORM SURGE HAZARD MAP
70 % of evacuation centers in Tacloban were hit by storm surges
Brgy Andap
566 people were placed in an evacuation center overwhelmed by debris flows (This picture) which is a
type of landslide
NO AMOUNT OF ACCURATE WARNING WILL WORK IF HAZARD MAPS ARE INAPPROPRIATE
What is Disaster Risk?
Risk = f (Hazard , Exposure , Vulnerability)

Why scenario-based maps are necessary
• While historical losses can explain the past, they do not necessarily provide a good guide to the future; most disasters that could happen have not happened yet (UNISDR, 2013). Probabilistic risk assessment simulates those future disasters which, based on scientific evidence, are likely to occur. (UNISDR, 2015).
