1.1 Disasters

What is a Disaster?

A disaster is a sudden event that severely disrupts the normal functioning of a community, causing significant human, economic, and environmental losses. According to the United Nations Office for Disaster Risk Reduction (UNDRR), a disaster occurs when hazards combine with vulnerabilities and inadequate measures to handle risks.

Disasters can result from:

1. Natural Events: These include earthquakes, hurricanes, tsunamis, and wildfires caused by natural processes.
2. Human-Made Causes: Examples include pollution, deforestation, industrial accidents, and unsafe urban development.

Impacts of Disasters

1. Human Losses:
   • Disasters can cause injuries, loss of life, and displacement, leaving survivors in need of urgent assistance.
2. Economic Damage:
   • Disasters often disrupt livelihoods and damage businesses and infrastructure, leading to significant financial losses.
3. Environmental Harm:
   • Disasters can destroy ecosystems, pollute natural resources, and harm biodiversity.

Measuring Disaster Damage

The extent of disaster damage is often measured in:

• Physical Units: Square meters of destroyed homes or kilometers of damaged roads.
• Economic Terms: Financial costs of recovery and rebuilding.
• Environmental Impact: Damage to natural resources, such as forests and wetlands.

1.2 Hazards, Vulnerabilities, and Risks in Disaster Management

Disasters occur when hazards interact with vulnerabilities in a community. Understanding these factors is crucial for effective disaster management.

Hazards

A hazard is any dangerous condition or event that has the potential to cause harm to people, property, or the environment. Hazards are classified into:

1. Natural Hazards: These result from natural processes and include:
   • Geophysical Hazards: Earthquakes, volcanic eruptions, landslides.
   • Hydrological Hazards: Floods and avalanches.
   • Climatological Hazards: Droughts, extreme temperatures, wildfires.
   • Meteorological Hazards: Hurricanes, cyclones, and severe storms.
   • Biological Hazards: Disease outbreaks, epidemics, and pest infestations.
   Example: Hurricanes, which involve strong winds and heavy rain, often lead to severe flooding and destruction of infrastructure.
2. Human-Made Hazards: These are caused by human actions or negligence, including:
   • Industrial Accidents: Chemical spills, gas leaks.
   • Deforestation: Leading to soil erosion and landslides.
   • Pollution: Contamination of air, water, and soil.

Vulnerabilities in Disaster Management

Vulnerability refers to the weaknesses or conditions that make a community more likely to suffer from the effects of a disaster. There are several types of vulnerabilities:

1. Economic Vulnerability:
   • Poorer communities often live in unsafe areas like floodplains or unstable slopes because they cannot afford safer housing.
2. Physical Vulnerability:
   • This refers to infrastructure and proximity to hazards. For example, homes built near rivers are more prone to flooding.
3. Social Vulnerability:
   • Certain groups, such as children, the elderly, and people with disabilities, face greater risks during disasters.
4. Environmental Vulnerability:
   • Fragile ecosystems, such as wetlands and forests, are highly sensitive to the effects of disasters.
5. Attitudinal Vulnerability:
   • Communities with a lack of awareness or a negative attitude toward disaster preparedness are often more dependent on external aid.

---

Risks in Disaster Management

Risk in Disaster Management is the likelihood of harm or damage occurring when a hazard interacts with vulnerabilities. It can be calculated using the formula:

Risk = Probability of Hazard × Degree of Vulnerability

For example:

• A well-prepared city with strong disaster management measures has a lower risk during a hurricane compared to an unprepared coastal village.

---

Managing Risks

Effective disaster management includes strategies to manage risks, such as:

1. Risk Acceptance:
   • A community decides to accept the potential consequences of a hazard if avoiding it is impractical or costly.
2. Risk Avoidance:
   • Avoiding activities or locations that increase exposure to hazards, such as not building homes in flood-prone areas.
3. Risk Reduction:
   • Implementing measures to reduce vulnerabilities, like constructing earthquake-resistant buildings.
4. Risk Transfer:
   • Transferring the financial burden of risk to another party, such as purchasing insurance to cover potential losses.

Classification of Disasters in Disaster Management

Disasters can be categorized based on their source and duration. These classifications help in designing specific strategies for effective disaster management and preparedness.

---

Classification Based on Source

1. Natural Disasters:
   Natural disasters are caused by natural phenomena, such as geological, meteorological, or biological processes. These disasters can further be divided into:
   • Exclusively Natural Disasters:
     These occur purely due to natural processes without any human interference. They are often sudden, unpredictable, and have widespread effects.
     Examples:
     • Cyclones: Storms with strong winds and heavy rainfall, formed by low-pressure systems over oceans.
     • Tsunamis: Massive sea waves triggered by underwater earthquakes or volcanic eruptions.
     • Earthquakes: Sudden shaking of the Earth’s surface due to tectonic plate movements.
     • Volcanic Eruptions: Explosive release of magma, gases, and ash from beneath the Earth’s crust.
   • Socio-Natural Disasters:
     These disasters arise from a combination of natural factors and human activities. Human negligence or poor planning often exacerbates their effects.
     Examples:
     • Floods: Caused by heavy rainfall, worsened by blocked drainage systems or unregulated urbanization.
     • Landslides: Triggered by natural rainfall but worsened by deforestation or mining activities.
     • Fires: Often started by lightning but spread due to uncontrolled human actions like unattended campfires.
2. Anthropogenic (Human-Made) Disasters:
   Anthropogenic disasters are caused by human activities, negligence, or technological failures. These events often result from industrial operations, energy production, or social conflicts.
   Examples:
   • Industrial Accidents: Fires, explosions, or toxic gas leaks in factories.
   • Toxic Waste Leaks: Contamination of water or soil due to improper disposal of hazardous materials.
   • Dam Failures: Collapse of dams due to poor maintenance or overpressure.
   • Pollution: Air, water, or land pollution caused by industrial emissions or waste mismanagement.
   • Wars and Civil Strife: Armed conflicts leading to loss of lives, destruction of infrastructure, and mass displacement.

Classification Based on Duration

Disasters are also classified based on how quickly they occur and the timeframe of their impact. They can be categorized into:

1. Rapid Onset Disasters:
   These disasters occur suddenly and have an intense impact over a short period of time. They are often unpredictable or come with limited warning.
   Examples:
   • Earthquakes: Lasting seconds or minutes, these can cause widespread destruction.
   • Cyclones: Although they form over days, their impact is sudden and often devastating.
   • Floods: Especially flash floods, which occur with little to no warning.
   • Tsunamis: Fast-moving sea waves that hit coastlines within minutes or hours of an underwater earthquake.
   Characteristics:
   • Occur with little warning.
   • Require immediate emergency response and rescue operations.
2. Slow Onset Disasters:
   Also known as Creeping Emergencies, these disasters develop gradually over time, sometimes taking months or years to unfold. They may allow for some preparation, but their long-term impacts on ecosystems and livelihoods are often severe.
   Examples:
   • Climate Change: Gradual warming of the planet caused by greenhouse gas emissions, leading to extreme weather events and rising sea levels.
   • Desertification: The transformation of fertile land into arid areas due to overgrazing, deforestation, and unsustainable agriculture.
   • Soil Degradation: Loss of soil fertility due to pollution, erosion, or overuse, leading to reduced agricultural productivity.
   • Droughts: Prolonged periods of water scarcity caused by low rainfall and poor water management.
   Characteristics:
   • Impact unfolds over time, often unnoticed initially.
   • Causes gradual degradation of livelihoods, forcing communities to adapt or migrate.
