Development Disability Index
Planning Commission's BK Chaturvedi Committee (2013) used this index, developed by the National Institue for Plan Finance & Policy, to calculate compensation to mountain states
Integrated Mountain Initiative
DDI contains 2 components
Geographical Area Disadvantage Index
Infrastructure Deficit Index
How much productive land is left for the use of the state, after removing area covered by forests & by barren, unculturable land?
How does the state fare on infrastructure for development, factoring in the area of hill districts and flood-prone zones?
DDI is an average of these
Indicators of Geographical Area Deficit
Barren & Unculturable Land Index
Forest Cover Index
Indicators of Infrastructure Deficit
Area of hill districts
DDI takes into account all these parameters and not just forest cover
