Disaster
synonymous with “risk”, a sudden calamitous event bringing great damage, loss, or destruction with unexpected timing
Elements of Disaster
suddenness
unexpectedness
significant/adverse destruction
lack of foresight/planning
Natural Disasters
this does not exist, but disasters usually follow natural hazards
Disaster Risk
the likelihood of the loss of life, injury, and destruction from a disaster in a period of time
Conditions for an event to be a disaster
loss of life/injuries
loss of property
Effects of Disaster
displaced populations
food scarcity
emotional aftershocks
Displaced Populations After Disasters
due to the dangers of these disasters, people may be forced to seek shelter in other places or regions
Food Scarcity After Disasters
due to the damage done to the soil quality and environment, food might not be as accessible
Emotional Aftershocks After Disasters
due to the suddenness of the disaster, trauma for young children and PTSD may occur
Impacts of Disaster
medical effects
damage to critical facilities
economic impact
global environmental change
social and political impact
Medical Effects of Disasters
injuries, emotional stress, epidemic diseases
Disruption of Transportation After Disaster
restricted vehicle mobility and impassable area
Economic Impact After Disaster
disrupted normal business operations and leaving of jobs to allow time for rehabilitation
Global Environmental Change After Disasters
evidence supports that human activity and disasters worsens global climate change
Social and Political Impact After Disasters
poor and developing countries are most affected by disasters
Levels of Disasters
Individual
Community (Local, National, Global)
Disaster Risk Reduction
the systematic process of analyzing and reducing risk linked to natural and human-induced disasters
mitigation measures are designed too minimize disaster-related losses
tells us that the levels of mitigation capabilities and preparedness are related to level of its resources
prevent or minimize the impact of disasters n lives, infrastructure, and the environment
involves understanding the causes of disasters
Key Principles of DRR
Risk Assessment
Prevention and Mitigation
Preparedness
Resilience
Risk Assessment in DRR
DRR begins with a thorough assessments of risks, including hazards, vulnerabilities, and exposure.
Prevention and Mitigation in DRR
DRR focuses on preventing or mitigating the root causes of disasters
Preparedness in DRR
DRR emphasizes the importance of preparedness to respond effectively to disasters
Resilience in DRR
DRR aims to build this in communities and ecosystems as it enables entities to absorb shocks, adapt to changes, and recover quickly from disasters.
Participation and Collaboration in DRR
DRR recognizes the imporance of inolving all stakeholders in risk reduction effors
Integrated Approach
DRR promotes an integrated approach that considers social, economic, environmental, and institutional aspects of risk.
Sustainable Development
DRR integrates risk
Importance of DRR
saving lives
minimizing losses
protecting infrastructure and assets
ensuring sustainable development
enhancing resilience
DRR before Disaster Risk
building code revision and implementation
hazard and vulnerability analysis
zoning and land use management
public awareness and education
early warning system with forecasting and warning dissemination
