Flood Mitigation and Natural Hazards

The video discusses the Indian subcontinent's vulnerability to natural hazards like floods, cyclones, earthquakes, and landslides. It emphasizes the importance of mitigation strategies, both structural and non-structural, to minimize disaster impacts. A case study of Ralegan Siddhi highlights community efforts in drought mitigation. The video outlines various mitigation measures, particularly for floods, and stresses the significance of preparedness and awareness in reducing disaster risks.

What are the main types of natural hazards affecting the Indian subcontinent?

• Floods, Cyclones, Earthquakes, Landslides
