Roadmap for Answer Writing
Introduction
- Purpose: Introduce the topic of landslides and their significance as natural disasters.
- Context: Highlight the need to understand causes, effects, and management strategies.
Causes of Landslides
- Geological Factors:
- Fact: Geological characteristics such as soil type, rock composition, slope angle, and stability contribute to landslide susceptibility.
- Example: In Himachal Pradesh, steep slopes with loose soil are particularly prone to landslides .
- Source: Geological surveys of India.
- Natural Factors:
- Fact: Natural triggers include heavy rainfall, snowmelt, earthquakes, and volcanic activity.
- Example: In Assam, heavy rainfall saturates the soil, leading to instability and landslides .
- Source: Indian Meteorological Department.
- Human Factors:
- Fact: Activities such as deforestation, mining, and construction increase landslide risks.
- Example: In Kerala, deforestation destabilizes slopes, contributing to landslides .
- Source: National Disaster Management Authority (NDMA).
Effects of Landslides
- Loss of Life:
- Landslides can result in fatalities and serious injuries to residents in affected areas.
- Damage to Property and Infrastructure:
- Fact: Landslides can destroy buildings, roads, bridges, and other infrastructure, causing significant economic losses .
- Environmental Damage:
- Fact: They can lead to soil erosion, loss of vegetation, and changes to local watercourses, causing long-term ecological harm .
Important Components of the National Landslide Risk Management Strategy
- Hazard Assessment:
- Fact: Identifying landslide-prone areas and evaluating potential impacts are essential first steps .
- Risk Mapping:
- Fact: Mapping vulnerable areas helps prioritize them for effective risk reduction measures .
