Disaster Risk Index

What?

A Disaster Risk Index (DRI) has been prepared that assigns scores to each state based on probability of hazard and vulnerability of the state to deal with disaster.

Why in news?

Recently, 15th Finance Commission has attempted a transparent methodology for disaster management based on Disaster Risk index.

How it is measured?

The DRI has been developed through a quantitative exercise assigning scores to the probability of hazards and the extent of vulnerability of a state.

Dimensions usedHazard zonation and risk exposure maps.
  1. Both income and non-income dimensions like poor housing, informal jobs, social isolation and remote terrains.

Internal division
  1. The four major hazards that have been assigned a score of 15 each are floods, drought, cyclone and earthquake. 
  2. The remaining score of 10 has been assigned equally to all states for smaller hazard like landslides, windstorms, hailstorm, cloud burst and lightening.
Area and population have been given weightage of 15 per cent each.
Other facts
The vulnerability has been assigned based on the below poverty line population. States with poverty rate of 26 per cent and above have been assigned the highest score of 30.
