JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech III DISASTER MANAGEMENT Previous Question Paper (March - 2021 - R16)

The Human Ecology approach in geography examines the reciprocal relationship between human societies and their environment. By analyzing how human activities alter ecosystems, this perspective identifies vulnerabilities that lead to environmental disasters and proposes sustainable interventions.

A prominent application of this approach is the Integrated Watershed Management (IWM) strategy, which is used to prevent disasters like flash floods and landslides in mountainous regions.

The application of this approach follows these key steps:

• Assessment of Human-Environment Interaction: Researchers analyze land-use patterns, such as deforestation for agriculture or unplanned urbanization, which destabilize slopes and reduce soil water retention capacity.
• Vulnerability Mapping: By mapping the ecological footprint of human settlements against topographic data, geographers identify high-risk zones prone to soil erosion and rapid runoff.
• Ecological Restoration: The approach mandates the implementation of terrace farming, afforestation with native species, and the construction of check dams. These interventions restore the natural hydrological cycle and stabilize the terrain.
• Community Participation: Recognizing that humans are part of the ecosystem, the approach involves local communities in managing natural resources, ensuring that economic activities do not exceed the carrying capacity of the land.

By shifting from a purely engineering-based disaster response to an ecological management framework, this approach addresses the root cause of environmental disasters rather than merely mitigating their symptoms. It ensures that human development remains within the limits of environmental resilience, effectively preventing disasters before they manifest.
