Frequently Asked Questions
What is the difference between a hazard and a disaster?
A hazard is a threatening event or condition with the potential to cause harm, whereas a disaster is the actual occurrence of that event that causes widespread destruction, loss of life, and disruption beyond the community's capacity to cope.
Why is Rajasthan particularly vulnerable to droughts?
Rajasthan experiences arid and semi-arid climatic conditions with erratic, scanty rainfall, high evaporation rates, and over-reliance on the southwest monsoon, making it highly prone to recurring droughts.
What are the main components of disaster management?
The main components include pre-disaster mitigation and preparedness, active response during the disaster, and post-disaster recovery, rehabilitation, and reconstruction.
