Study Notes
Definition of Disaster
- A disaster entails a sudden, significant disruption affecting a community's functioning, resulting in extensive losses surpassing local recovery capabilities.
- Involves a combination of hazard exposure, vulnerability conditions, and insufficient coping resources.
Types of Disasters
- Natural Disasters: Caused by natural forces such as earthquakes, typhoons, volcanic eruptions, fires, and droughts.
-
Man-Made Disasters: Result from human actions, intentional or not, including bridge collapses, chemical leaks, vehicle collisions, bomb explosions, and conflicts.
- Further categorized into:
- Technological/Industrial: Arising from technological advancements.
- Terrorism/Violence: Acts intended to cause harm.
- Complex Humanitarian Emergencies: For example, pandemics.
- Further categorized into:
Perspectives on Disasters
- Physical Perspective: Focuses on damage to infrastructure, people, and property; influenced by disaster magnitude, geography, and recovery efforts.
- Psychological Perspective: Addresses mental health issues suffered by victims, including distress and PTSD.
- Sociocultural Perspective: Examines changes in community roles and disruption of social relationships post-disaster.
- Economic Perspective: Highlights impacts on trade, unemployment, and asset loss.
- Political Perspective: Considers government roles in disaster management; affects public trust in agencies and acceptance of policies.
- Biological Perspective: Relates to large-scale effects of diseases or viruses as biological disasters.
Disaster Risk
- Represents potential losses in lives, health, and assets that might occur due to hazards.
- Expressed through the formula: Hazard X Elements at Risk X Vulnerability, incorporating the likelihood of event occurrence.
Risk Factors
- Climate Change: Intensifies disaster risk through altered hazard frequency and community vulnerability.
- Environmental Degradation: Compromises the environment's ability to meet social and economic needs, exacerbating disaster impacts.
- Globalized Economic Development: Prioritizes industrial growth over protecting vulnerable sectors.
- Poverty and Inequality: Increases vulnerability among low-income families.
- Poor Urban Planning: Necessitates adequate housing and infrastructure to mitigate disaster impact.
- Weak Governance: Governments must be equipped with training for effective disaster preparation.
Exposure or Elements at Risk
- Elements at risk from hazards include:
- Physical Elements: Population density, infrastructure materials, and settlement locations are often severely impacted.
- Social Elements: Inability of societies to manage hazards due to prevailing social norms.
- Economic Elements: Economic status influences vulnerability; poorer nations are generally more at risk.
- Environmental Elements: Dependency on natural resources heightens community vulnerability.
Vulnerability
- Refers to characteristics and conditions that hinder a community's ability to prevent and respond to hazards.
- Determined by physical, social, economic, and environmental factors, indicating the likelihood of experiencing a disaster.
- Reasons for disaster severity include poor infrastructure design, asset protection ineffectiveness, lack of awareness, and insufficient risk preparedness.
Sectors of Vulnerability
- Most Vulnerable Sector: Includes marginalized groups such as farmers, urban poor, laborers, indigenous individuals, women, and children with low capacities to withstand disasters.
- Less Vulnerable Sector: Comprises professionals and small entrepreneurs with greater capacity to recover from disasters.
