The affected populations face severe multidimensional challenges:
• Security threats: Civilians caught in crossfire, subjected to violence and kangaroo courts (‘Jan Adalats’)
• Development deficit: Destruction of infrastructure (schools, roads, telecom towers) perpetuates poverty cycles
• Democratic denial: Killing of elected representatives creates governance vacuum
• Displacement: Forced migration disrupts traditional livelihoods
• Psychological trauma: Children growing up amid constant violence

Government’s Multi-Pronged Strategy:

The SAMADHAN doctrine combines security and development approaches:

Security measures:
• Deployment of specialized forces (CoBRA battalions, Greyhounds-Andhra Pradesh)
• Fortified police stations and intelligence-based operations
• Modernization of state police forces

Development initiatives:
• Road Connectivity Project for LWE areas (RCPLWE)
• Mobile tower installations improving connectivity
• Eklavya Model Residential Schools for tribal education
• Skill Development Centers and ITIs

Rights and rehabilitation:
• Forest Rights Act implementation
• Civic Action Programme building trust
• Surrender policies with vocational training

Conclusion: Violence declined from 2,258 incidents (2009) to ~500 recently, validating the holistic approach toward 2026 elimination target.

Q. Distinguish between the Human Development Index (HDI) and the Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?

Q. Distinguish between the Human Development Index (HDI) and the Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?

UPSC Mains 2025 GS3 Paper

Model Answer:

Distinguishing HDI and IHDI with Reference to India

The Human Development Index (HDI) measures a country’s average achievements in three dimensions: health (life expectancy), education (schooling years), and living standards (GNI per capita). It provides a composite score between 0-1 for international comparison. India’s HDI stands at 0.644, ranking 134th globally in 2022.

The Inequality-adjusted Human Development Index (IHDI) adjusts HDI by accounting for inequalities in distribution of these achievements across the population. While HDI represents potential development assuming perfect equality, IHDI reflects actual human development experienced by citizens.

India’s Reality:
• HDI (2022): 0.644 (medium development category)
• IHDI (2022): 0.444 – representing 31.1% loss due to inequality
• Major disparities: Urban-rural divide, caste differences, gender gaps
• Regional variations: Kerala vs Bihar, Northeast vs BIMARU states

Why IHDI is Superior for Inclusive Growth:

• Reveals hidden disparities: HDI’s national averages mask internal inequalities; IHDI exposes the reality of marginalized sections (tribal areas, urban slums)

• Quantifies inequality cost: The 31.1% loss clearly shows development not reaching all citizens equally

• Enables targeted interventions: Identifies specific dimensions needing attention – education inequality highest in India

• Aligns with SDGs: Directly measures “leaving no one behind” principle, especially SDG-10

Conclusion: IHDI provides honest assessment of inclusive development, crucial for India’s equitable growth trajectory.
