Study Notes

Geographic Regions

Major Indian states include Uttarakhand, Uttar Pradesh, Jharkhand, Bihar, West Bengal, Punjab, Haryana, Himachal Pradesh, Rajasthan, Madhya Pradesh, and Delhi.
Rivers central to the region: Narmada, Tapi, Mahanadi, Godavari, Krishna, and Cauvery.
Additional states in focus: Andhra Pradesh, Karnataka, Tamil Nadu, Kerala, Odisha, Maharashtra, and Gujarat.

Flood Mitigation Measures

Natural hazards cannot be fully prevented but can be mitigated through proper planning and disaster management.
Mitigation measures aim to reduce risks associated with hazards and are divided into two categories:
- Structural measures: Physical constructions to minimize disaster impacts, such as reservoirs, dams, embankments, and water storage systems.
- Non-structural measures: Policies, regulations, awareness programs, and management practices that do not involve physical constructions, e.g., land use planning and public education.

Cyclone Mitigation Strategies

Structural measures include the construction of cyclone shelters, roads, bridges, drains, and saline embankments for coastal protection.
Effective communication and network towers are recommended based on historical cyclone data.
Non-structural measures focus on early warning systems, public awareness, coastal zone management, and hazard mapping to enhance preparedness.

Drought Management

Timely declaration of drought in three phases (end of July, September, and November) based on rainfall impacts and agricultural conditions.
Interim relief and final relief measures are implemented based on drought assessments.
Collaboration between State Disaster Management Authority (SDMA) and other agencies for financial support post-drought declaration.

Cloud Bursts

Occur when heavy rainfall from thunderstorms exceeds river capacity, leading to flash floods and extensive damage.
Triggered by orographic lifting, where moist air rises and cools, preventing rain from dissipating over mountains or steep slopes.

Heat Waves

Heat-related conditions: Heat cramps, exhaustion, and stroke with body temperatures rising above 40°C, potentially resulting in death.
Labor productivity suffers, with an estimated loss of 162 hours per year due to heat exposure, affecting vulnerable workers like farmers and construction workers.
Crop yields decline from high temperatures, leading to food insecurity and increased prices.
Energy demand spikes as temperatures rise, reflecting the higher peak demand.

Cold Waves

Cold wave conditions are characterized by significant drops in temperatures in winter (November to March), primarily affecting human health.
Symptoms include respiratory illnesses, blood pressure issues, skin problems, and muscle pain.
IMD defines cold waves with specific temperature criteria, such as minimum temperatures dropping below 10°C in plains and 0°C in hilly areas.
Severe cold waves are defined by more extreme temperature drops.
