Environmental Geography and Disaster Management
Environmental geography examines ecosystems, pollution, conservation and human-environment interaction; disaster management applies hazard, vulnerability and capacity ideas. Odisha’s cyclone and flood exposure makes this domain especially applied.
Core rules and concepts
- A hazard is a potential event; a disaster occurs when a hazard affects exposed and vulnerable people beyond their capacity to cope. Risk can be treated as hazard × exposure × vulnerability, with capacity reducing impact.
- The disaster cycle includes mitigation, preparedness, response and recovery. Mitigation reduces long-term risk; preparedness readies warnings, shelters and stocks; response is immediate action; recovery restores services and livelihoods.
- Odisha faces cyclones, floods, drought, heat waves and coastal erosion. The 1999 super cyclone and Cyclone Phailin in 2013 are standard examples of the need for early warning, evacuation and multi-purpose cyclone shelters.
- Environmental management includes pollution control, mangrove and coastal protection, waste segregation, biodiversity conservation and watershed treatment.
Worked example
Two coastal villages face the same cyclone. Village A has no warning system, weak houses and no shelter; Village B has warnings, concrete shelters and evacuation drills. The hazard is equal, but Village A’s disaster risk is far higher because exposure and vulnerability are greater and capacity is lower. This shows why disaster management is not only about controlling nature.
Traps that cost marks
- Treating every hazard as a disaster regardless of exposure.
- Confusing mitigation with emergency response.
- Mixing weather with climate.
- Assuming all disasters are purely natural; poverty and poor planning increase vulnerability.
