Study Notes
Economic Impact of Disasters
- Significant job losses and economic downturns recorded due to the pandemic.
- Strain on healthcare systems revealed vulnerabilities in public health strategies.
- Global inequalities have been amplified, necessitating a reevaluation of existing approaches.
Disaster Management
- Defined by the Disaster Management Act of 2005 as a coordinated process of planning, organizing, and implementing strategies.
- Aims to prevent disasters, reduce risks, prepare for threats, respond during emergencies, assess impacts, and facilitate recovery.
- Includes rescue, relief, rehabilitation, and reconstruction efforts to rebuild affected communities.
Disaster Warning Systems
- Integrated systems monitoring hazards, forecasting, predicting risks, and assessing vulnerabilities.
- Enable timely communication and preparedness, allowing proactive measures by communities and authorities.
- Notable examples include:
- Cyclone Warning Systems in India: Effective early alarms for Cyclone Fani in 2019 led to mass evacuations, minimizing casualties.
- Tsunami Warning Systems: Enhanced following the 2004 Indian Ocean tsunami for better detection and alerts.
Components of Disaster Warning Systems
- Hazard Monitoring: Continuous observation of potential hazards such as earthquakes and storms.
- Forecasting and Prediction: Employing data to predict upcoming hazards, considering frequency and predictability (e.g., cyclones vs. earthquakes).
Understanding Disasters
- Definition: Catastrophic events disrupting the environment and societal functions, stemming from natural hazards (e.g., earthquakes) or human activities (e.g., pollution).
- Disasters arise from hazardous events interacting with exposure, vulnerability, and capacity, leading to severe consequences.
Types of Disasters
-
Natural Disasters:
- Geological: Earthquakes, volcanic eruptions, landslides.
- Hydrological: Floods, tsunamis.
- Meteorological: Hurricanes, tornadoes.
- Climatological: Droughts, heatwaves.
- Biological: Pandemics, epidemics.
-
Human-Made Disasters:
- Industrial: Chemical spills, nuclear accidents.
- Environmental Pollution: Oil spills, air and water pollution.
- Technological: Power outages, cyber attacks.
- Socio-Political: Wars, terrorist attacks.
Impact of Disasters
- Human Impact: Loss of life and injuries, along with large-scale displacement.
- Material Impact: Damage to properties and livelihoods, disrupting businesses.
- Economic Impact: Increased response costs and economic disruptions affecting markets and trade.
- Environmental Impact: Habitat destruction, pollution, and depletion of natural resources.
Environmental Risks and Vulnerability
- Environmental Risk: Potential hazards that threaten the environment and human health, influenced by factors like pollution and urban sprawl.
- Environmental Vulnerability: The susceptibility of communities and ecosystems to damage from environmental risks.
Disaster Classification
- Disasters categorized based on origin and impact:
- Natural Disasters: Resulting from natural events such as earthquakes and floods.
- Man-Made Disasters: Arising from human actions, including industrial accidents and pollution.
Specific Natural Disasters
- Floods: Caused by heavy rainfall or dam failures; significant example is the 2013 Uttarakhand Floods in India.
- Earthquakes: Sudden energy release in Earth's crust causing destruction; notable is the 2010 Haiti Earthquake (7.0 magnitude).
- Cyclones: Strong storms leading to coastal damage; Cyclone Fani in 2019 affected millions in India.
- Tsunamis: Massive sea waves from seismic activity; exemplified by the 2004 Indian Ocean Tsunami with over 230,000 fatalities.
