Man-Made Disasters


 

A man-made disaster (also called a technological disaster or anthropogenic disaster) is a catastrophic event caused directly or indirectly by human actions, rather than natural processes. These disasters arise due to negligence, error, industrial activity, conflict, or misuse of technology, and often result in loss of life, property damage, and environmental degradation.

Terminology:

  • Anthropogenic = originating from human activity.

  • Technological hazard = hazard caused by failure or misuse of technology or industry.

🔹 Conceptual Understanding

Man-made disasters are part of the Disaster Management Cycle, which includes:

  1. Prevention – avoiding unsafe practices.

  2. Mitigation – reducing disaster impact (e.g., safety regulations).

  3. Preparedness – training and planning.

  4. Response – emergency actions after the disaster.

  5. Recovery – long-term rebuilding and policy correction.

These disasters are predictable and preventable through strong governance, technology regulation, and environmental ethics.

🔹 Classification of Man-Made Disasters

1. Industrial and Technological Disasters

Caused by industrial accidents, chemical leaks, nuclear failures, or technological breakdowns.

Examples:

  • Bhopal Gas Tragedy (India, 1984):
    A gas leak from the Union Carbide pesticide plant released methyl isocyanate (MIC), killing over 3,000 people instantly and affecting more than half a million.
    ➤ Concept: Chemical disaster caused by industrial negligence.

  • Chernobyl Nuclear Disaster (Ukraine, 1986):
    Explosion in a nuclear reactor due to design flaws and human error.
    ➤ Terminology: Radioactive contamination and nuclear fallout.

  • Fukushima Daiichi Nuclear Disaster (Japan, 2011):
    Triggered by an earthquake and tsunami, but the meltdown was due to technological failure in cooling systems.

2. Environmental and Ecological Disasters

Result from unsustainable human exploitation of the environment.

Examples:

  • Deforestation and Desertification:
    Human-induced forest loss in Amazon or Africa leading to biodiversity loss, soil erosion, and climate imbalance.

  • Oil Spills:
    Deepwater Horizon (Gulf of Mexico, 2010) spilled 4.9 million barrels of crude oil.
    ➤ Terminology: Marine pollution and ecosystem collapse.

  • E-waste and Plastic Pollution:
    Caused by improper disposal of technological and consumer waste, especially in developing countries.

3. Transportation and Structural Disasters

Caused by failure in transport or infrastructure systems.

Examples:

  • Airplane Crashes:
    Malaysia Airlines Flight MH370 (2014) disappearance due to technical or human failure.
    ➤ Concept: Aviation disaster.

  • Bridge Collapse:
    Morbi Bridge Collapse (India, 2022) – structural failure due to poor maintenance and overloading.

  • Train Derailments or Ship Accidents:
    Human error or faulty engineering (e.g., Titanic sinking, 1912).

4. Armed Conflict and Terrorism

Man-made disasters also include war, terrorism, and civil unrest, which devastate human life and infrastructure.

Examples:

  • World War II (1939–1945):
    Use of atomic bombs on Hiroshima and Nagasaki caused mass destruction.
    ➤ Terminology: Weapons of mass destruction (WMDs).

  • 9/11 Attacks (USA, 2001):
    Terrorist attacks on the World Trade Center and Pentagon.
    ➤ Concept: Terrorist disaster and mass casualty event.

  • Civil Wars and Refugee Crises:
    Ongoing conflicts (e.g., Syria, Sudan) leading to humanitarian disasters.

5. Cyber and Technological Disasters

Modern form of man-made disaster caused by cyber-attacks, data theft, or digital infrastructure failure.

Examples:

  • Cyberattack on Colonial Pipeline (USA, 2021):
    Ransomware attack disrupted fuel supply.
    ➤ Terminology: Cyber disaster and critical infrastructure vulnerability.

  • Social Media Misinformation:
    Leading to panic, violence, or misinformation during crises (e.g., fake news during pandemics).

Causes of Man-Made Disasters

  1. Industrialization without safety measures

  2. Negligence or corruption in enforcement

  3. War and terrorism

  4. Environmental exploitation

  5. Urban overcrowding and poor planning

  6. Technological dependence and cyber insecurity

Consequences

  • Human loss: Deaths, injuries, long-term health effects.

  • Economic loss: Infrastructure damage, production loss.

  • Environmental degradation: Air, water, and soil pollution.

  • Social disruption: Migration, unemployment, trauma.

  • Political impact: Policy reforms, public distrust.

Mitigation and Management

  1. Policy and Legislation:

    • India's Disaster Management Act (2005) includes both natural and man-made disasters.

    • National Disaster Management Authority (NDMA) develops response frameworks.

  2. Technology and Early Warning Systems:

    • IoT-based monitoring, safety audits, AI-based industrial surveillance.

  3. Education and Awareness:

    • Worker training, public safety drills, chemical handling norms.

  4. Sustainability and Ethics:

    • Promoting corporate social responsibility (CSR) and environmental ethics.

Accuracy Assessment

Accuracy assessment is the process of checking how correct your classified satellite image is . 👉 After supervised classification, the satellite image is divided into classes like: Water Forest Agriculture Built-up land Barren land But classification is done using computer algorithms, so some areas may be wrongly classified . 👉 Accuracy assessment helps to answer this question: ✔ "How much of my classified map is correct compared to real ground conditions?"  Goal The main goal is to: Measure reliability of classified maps Identify classification errors Improve classification results Provide scientific validity to research 👉 Without accuracy assessment, a classified map is not considered scientifically reliable . Reference Data (Ground Truth Data) Reference data is real-world information used to check classification accuracy. It can be collected from: ✔ Field survey using GPS ✔ High-resolution satellite images (Google Earth etc.) ✔ Existing maps or survey reports 🧭 Exampl...

Change Detection

Change detection is the process of finding differences on the Earth's surface over time by comparing satellite images of the same area taken on different dates . After supervised classification , two classified maps (e.g., Year-1 and Year-2) are compared to identify land use / land cover changes .  Goal To detect where , what , and how much change has occurred To monitor urban growth, deforestation, floods, agriculture, etc.  Basic Concept Forest → Forest = No change Forest → Urban = Change detected Key Terminologies Multi-temporal images : Images of the same area at different times Post-classification comparison : Comparing two classified maps Change matrix : Table showing class-to-class change Change / No-change : Whether land cover remains same or different Main Methods Post-classification comparison – Most common and easy Image differencing – Subtract pixel values Image ratioing – Divide pixel values Deep learning methods – Advanced AI-based detection Examples Agricult...

Development and scope of Environmental Geography and Recent concepts in environmental Geography

Environmental Geography studies the relationship between humans and nature in a spatial (place-based) way. It combines Physical Geography (natural processes) and Human Geography (human activities). A. Early Stage 🔹 Environmental Determinism Concept: Nature controls human life. Meaning: Climate, landforms, and soil decide how people live. Example: People in deserts (like Sahara Desert) live differently from people in fertile river valleys. 🔹 Possibilism Concept: Humans can modify nature. Meaning: Environment gives options, but humans make choices. Example: In dry areas like Rajasthan, people use irrigation to grow crops. 👉 In this stage, geography was mostly descriptive (explaining what exists). B. Evolution Stage (Mid-20th Century) Environmental problems increased due to: Industrialization Urbanization Deforestation Pollution Geographers started studying: Environmental degradation Resource management Human impact on ecosystems The field became analytical and problem-solving...

Geographic phenomena fields objects boundaries.

In geography, geographic phenomena refer to features or processes that can be observed and studied on Earth's surface. These phenomena can be classified into three main categories: fields , objects , and boundaries . Each category has distinct characteristics, representations, and applications in Geographic Information Systems (GIS). 1. Fields A field represents continuous, spatially varying data where a value is present at every location within the study area. It describes conditions that exist across a geographic area. Characteristics : Continuity : Fields have no discrete boundaries; the data is continuous. Gradual Variability : The values of a field change gradually across space. Representation : Typically modeled using raster data in GIS, where a grid structure assigns a value (e.g., temperature or elevation) to each cell. Examples : Temperature Map : Shows temperature variation across a region. Rainfall Distribution : Displays rainfall levels over a large g...
