8th Mar, 2022
- India is a diverse country in terms of climate, terrain and relief and thus is prone to different types of disasters which include manmade disasters as well as natural disasters.
- Rapid industrial development and urbanization coupled with effects of climate change has aggravated the disasters in India. India has witnessed a large number of disasters since Independence.
This brief aims to analyse the major disasters in India since its independence and also assess how the government has managed them.
