Floods, Landslides, and Natural Disaster Data in India (Projected till 2025)

Natural disasters like floods and landslides cause significant damage in India annually. Below is statistical information based on recent data and projections:

Flood-prone area:

Out of India's total area of 329 million hectares, over 40 million hectares (more than 12%) are prone to flooding. Annually, an average of 7.5 million hectares is affected by floods.

Loss of life and property:

Approximately 1,600 lives are lost to floods annually. The average annual damage in the last decade (1996-2005) was 47.45 billion INR, significantly higher than the previous 53-year average of 18.05 billion INR.

Displacement:

Between 2015 and 2024, 32 million people in India were displaced by disasters such as floods, storms, and landslides. In 2024 alone, people were displaced 45.8 million times.

Crops and property:

Floods cause an annual loss of 18.05 billion INR to crops, homes, and public facilities, and the figure is rising.

Impact of climate change:

Weather-related disasters (floods, storms) caused 219 million displacements over the last decade, averaging 22.4 million annually.
