Disaster MANAGEMENT, Disaster Management in India involves making policies, laws and other courses of action aimed at conserving lives and property during natural or man-made disasters.
India faces a diverse range of hazards, including floods, cyclones, earthquakes, and pandemics. Here are some key aspects of disaster management in India:
National Disaster Management Authority (NDMA):
The NDMA, headed by the Prime Minister of India, is the apex body responsible for disaster management.
It was established under the Disaster Management Act, 2005.
NDMA focuses on creating an enabling environment for institutional mechanisms at the state and district levels.
Geo-climatic Conditions:
India’s unique location below the Himalayas and its varied landscapes make it vulnerable to natural disasters.
Monsoons, landslides, floods, droughts, cyclones, and earthquakes impact different regions to varying degrees.
Overpopulated areas face higher risks during disasters.
Importance of Communication in
Effective communication during and after disasters is crucial for several reasons:
Saving Lives: Accurate information helps people take protective actions, reducing risk.
Property Protection: Understanding risk mitigation measures minimizes damage to property and the environment.
Calming Fears: Well-delivered messages manage expectations, facilitate tactical responses, and instill public confidence.
Reuniting Families: Information helps families reconnect during recovery.
Public information serves as a lifeline, comparable to food and water, during emergencies.
