Study Notes
Natural Hazards and Disasters
- Severity of impact depends on population vulnerability and societal capacity to manage hazards.
- Natural hazards arise from unfavorable interactions between natural processes and human actions or environments.
- Communities’ primary concerns regarding natural hazards are managed by disaster management professionals.
- Types of natural hazards faced are influenced by climate, geography, geology, and land-use practices.
- Natural disasters occur when hazards cause significant destruction to life or property.
Types of Natural Hazards
- Cyclone: A potent low-pressure system characterized by strong spiral winds rotating counter-clockwise in the northern hemisphere.
Impacts of Natural Hazards
- Long-term consequences include tangible (e.g., property damage) and intangible (social, environmental, economic) losses.
- Economic impacts encompass:
- Business interruptions from access issues.
- Job losses and restricted work access.
- Reduced government income from tax shortfalls during crises.
- Negative impact on Gross Domestic Product (GDP).
Dimensions of Exposure
- Physical Exposure: Relates to the geographical location and asset presence in hazard-prone areas.
- Social Exposure: Influenced by demographics like age, health, income, education, and social networks.
- Economic Exposure: Encompasses the economic value of assets at risk and potential financial losses.
- Environmental Exposure: Concerns natural ecosystems vulnerable to hazards and their ability to mitigate impacts.
Vulnerability to Hazards
- Vulnerability refers to the potential loss of elements due to hazards of varying severity.
- Factors determining vulnerability include physical, social, economic, and environmental conditions.
- Recent natural disasters in the Philippines underscore the need for vulnerability assessments to optimize resource allocation for disaster preparedness.
Vulnerable Populations
- Certain demographics face higher vulnerability, including:
- Individuals with disabilities.
- Children and seniors.
- People requiring medication.
- Women, particularly single or unemployed.
- Ethnic minorities and marginalized groups.
- Homeless and incarcerated individuals.
Urbanization and Vulnerability
- Developing nations experience higher vulnerability due to rapid urbanization and inadequate resources to adapt.
- The world’s urban population has quintupled over the past 60 years, especially in less-developed countries.
- By 2025, it is projected that two-thirds of the world's population will reside in urban areas.
- Increased informal settlements in risk-prone regions heighten exposure to natural disasters, such as floods and landslides.
