Lesson Content/Board Summary

Causes And Effects Of Disasters

Causes of Disasters

Disasters are serious disruptions to the functioning of a community or society involving widespread human, material, economic or environmental losses and impacts, which exceed the ability of the affected community or society to cope using its own resources. The causes of disasters can be broadly categorised into natural and human-induced factors:

  1. Natural Causes: These are events or forces of nature that lead to disasters.
    1. Geological Disasters: Caused by processes within the Earth. Examples include earthquakes, volcanic eruptions, tsunamis, and landslides.
    2. Hydro-meteorological Disasters: Caused by atmospheric, hydrological, and oceanographic phenomena. Examples include floods (riverine, coastal, flash), droughts, hurricanes/typhoons/cyclones, severe storms, heatwaves, cold waves, and wildfires.
    3. Biological Disasters: Involve the spread of disease or infestation. Examples include epidemics (e.g., cholera, Lassa fever, COVID-19), pandemics, and pest infestations affecting crops.
  2. Human-Induced Causes: These are disasters resulting from human activities, negligence, or failures.
    1. Technological Disasters: Result from industrial accidents, infrastructure failures, or hazardous material spills. Examples include oil spills, industrial explosions (e.g., gas explosions), building collapses, and nuclear accidents.
    2. Environmental Degradation: Human activities that harm the environment can exacerbate natural hazards. Examples include deforestation leading to landslides and soil erosion, improper waste disposal causing urban flooding, and climate change due to greenhouse gas emissions.
    3. Conflicts and Violence: Wars, civil unrest, terrorism, and communal clashes can lead to humanitarian crises, displacement, and destruction. Examples include insurgencies (e.g., Boko Haram in Nigeria), ethnic conflicts, and political violence.
    4. Poor Planning and Infrastructure: Lack of proper urban planning, construction of buildings in flood-prone areas, and inadequate infrastructure (e.g., poor drainage systems) can turn hazards into disasters.
    5. Negligence and Human Error: Accidents due to human mistakes, such as road accidents, fire outbreaks from carelessness, or mismanagement of resources, can trigger disasters.

Effects of Disasters on Communities and the Nation

Disasters have profound and devastating effects across various aspects of community and national life. These impacts are often interconnected and can hinder progress for many years.

Social Effects

The social effects of disasters directly impact people’s lives, health, and well-being:

  1. Loss of Life and Injury: Disasters often result in fatalities, severe injuries, and disabilities, leading to immense human suffering and grief.
  2. Displacement of Populations: Many people are forced to evacuate their homes, becoming internally displaced persons (IDPs) or refugees, leading to overcrowding in temporary shelters and loss of livelihoods. For example, flood victims in Benue State or conflict-affected communities in the North-East of Nigeria.
  3. Psychological Trauma: Survivors often experience severe psychological distress, including anxiety, depression, post-traumatic stress disorder (PTSD), and other mental health issues.
  4. Disruption of Social Services: Schools, hospitals, and other essential services are often damaged or destroyed, hindering education, healthcare, and social support systems.
  5. Breakdown of Social Cohesion: Disasters can strain community bonds, leading to increased crime, social unrest, and competition for scarce resources, although sometimes they can also foster community solidarity.
  6. Loss of Cultural Heritage: Historical sites, cultural artifacts, and traditional practices can be destroyed or lost, eroding a community’s identity and heritage.
Economic Effects

Disasters inflict significant economic damage, affecting livelihoods, infrastructure, and national economies:

  1. Destruction of Infrastructure: Roads, bridges, power lines, communication networks, and public buildings are often destroyed or severely damaged, requiring massive reconstruction efforts.
  2. Loss of Livelihoods: Agriculture (farms, livestock), businesses, and industries are disrupted or destroyed, leading to job losses, reduced income, and increased poverty. For instance, farmers in the Lake Chad region affected by drought and insurgency.
  3. Damage to Property: Homes, commercial buildings, and personal belongings are lost, incurring huge costs for repair or replacement.
  4. Impact on Key Economic Sectors: Industries such as agriculture, tourism, manufacturing, and mining can suffer severe setbacks, affecting national GDP.
  5. Increased Government Expenditure: Governments incur huge costs for emergency response, relief operations, rehabilitation, and reconstruction, often diverting funds from development projects.
  6. Food Insecurity: Destruction of crops and livestock, along with disrupted supply chains, can lead to food shortages and increased prices, exacerbating hunger.
Political Effects

Disasters can also have significant political ramifications, affecting governance, stability, and international relations:

  1. Governance Challenges: Disasters can expose weaknesses in governance, emergency preparedness, and response mechanisms, leading to public dissatisfaction and loss of trust in government.
  2. Political Instability: In severe cases, widespread suffering and perceived government inaction can fuel social unrest, protests, and even political instability or conflict.
  3. Resource Allocation Disputes: Competition for relief aid and reconstruction funds can lead to political disputes and accusations of favouritism or corruption.
  4. International Relations: Disasters often necessitate international aid and cooperation, influencing diplomatic relations and highlighting a nation’s capacity to manage crises.
  5. Policy Changes: Governments may be compelled to review and strengthen disaster risk reduction policies, building codes, and environmental regulations in response to major disasters.

Relationship Between Disaster and Development

The relationship between disaster and development is cyclical and interdependent. Disasters can reverse years of development gains, while unsustainable development practices can increase vulnerability to disasters.

  1. Disasters Hinder Development:
    1. Economic Setbacks: Disasters destroy infrastructure, disrupt economic activities, and divert financial resources from long-term development projects to immediate relief and recovery. This can lead to increased poverty and debt.
    2. Social Regression: Loss of lives, displacement, and disruption of education and health services set back human development indicators, affecting quality of life and future productivity.
    3. Environmental Degradation: Disasters can cause further environmental damage, such as soil erosion or pollution, which then impacts agricultural productivity and natural resource availability, crucial for sustainable development.
    4. Increased Vulnerability: Repeated disasters can trap communities in a cycle of poverty and vulnerability, making it harder for them to recover and build resilience.
  2. Development Influences Disaster Risk:
    1. Unsustainable Development: Rapid and unplanned urbanisation, deforestation, construction in hazardous zones (e.g., floodplains, coastal areas), and industrial pollution can increase exposure and vulnerability to hazards. For example, building on wetlands increases flood risk.
    2. Poverty and Inequality: Poor communities often live in unsafe areas, in poorly constructed homes, and lack access to resources and information, making them more vulnerable to disasters. Unequal access to resources can also hinder effective disaster response and recovery.
    3. Infrastructure Development: Well-planned and resilient infrastructure (e.g., strong buildings, effective drainage systems, early warning systems) can significantly reduce disaster impacts. Conversely, weak or poorly maintained infrastructure can amplify disaster effects.
    4. Policy and Governance: Effective governance, robust land-use planning, enforcement of building codes, and investment in disaster risk reduction (DRR) strategies are essential for reducing disaster risk and promoting sustainable development.
  3. Building Resilience through Development:
    1. Integrating DRR into Development: Incorporating disaster risk reduction measures into all development planning and projects (e.g., climate-resilient agriculture, disaster-proof infrastructure) is crucial.
    2. Sustainable Practices: Promoting environmental conservation, sustainable resource management, and climate change adaptation helps reduce the frequency and intensity of natural hazards.
    3. Capacity Building: Investing in education, healthcare, and community empowerment strengthens the capacity of individuals and communities to prepare for, respond to, and recover from disasters.
