Q. Seawater intrusion in the coastal aquifers is a major concern in India. What are the causes of seawater intrusion and the remedial measures to combat this hazard?

UPSC Mains 2025 GS3 Paper

Model Answer:

India’s ~7,500 km coastline faces severe groundwater salinization as excessive freshwater extraction disrupts the natural Ghyben-Herzberg balance, contaminating critical coastal aquifers.

1. Causes of Seawater Intrusion

  • Groundwater Over-extraction: Unregulated pumping for agriculture and industries reverses seaward hydraulic gradients, pulling saltwater inland (e.g., Minjur aquifer, Chennai).
  • Climate Change & Sea-Level Rise: Rising sea levels and frequent cyclonic storm surges push the marine saline wedge further inland (e.g., Sundarbans).
  • Unregulated Aquaculture: Extensive brackish-water shrimp farming leaks high-salinity water into shallow coastal aquifers (e.g., Andhra Pradesh coast).
  • Reduced Natural Recharge: Urban concretization and destruction of coastal wetlands restrict freshwater percolation, preventing natural aquifer flushing.

2. Remedial Measures to Combat the Hazard

  • Artificial Recharge: Pumping rainwater or treated wastewater into injection wells to build a freshwater ridge and restore hydrostatic pressure (e.g., Saurashtra recharge initiatives).
  • Structural Barriers: Constructing subsurface dams, tidal regulators, and coastal embankments to physically block salinity ingress.
  • Regulatory Enforcement: Strict enforcement of Central Ground Water Authority (CGWA) guidelines for coastal pumping and CRZ 2019 restrictions on borewells.
  • Agro-Ecological Shifts: Promoting saline-tolerant crop varieties (e.g., Pokkali rice) and restoring mangrove bio-shields to reduce groundwater dependency and regulate coastal hydrology.

Combating coastal salinity requires an Integrated Coastal Zone Management (ICZM) approach, combining scientific groundwater budgeting with ecological restoration to ensure long-term water security.

Q. What are the challenges before the Indian economy when the world is moving away from free trade and multilateralism to protectionism and bilateralism? How can these challenges be met?

UPSC Mains 2025 GS3 Paper

Model Answer:

The global shift towards “slowbalisation,” marked by protectionism, friend-shoring, and WTO paralysis, poses critical structural risks to India’s export-led growth ambitions.

1. Challenges for the Indian Economy

  • Export Competitiveness: Rising non-tariff barriers and unilateral tariffs threaten key Indian exports (e.g., EU-CBAM impact on domestic steel/aluminum).
  • Supply Chain Vulnerability: Tech-nationalism and export controls disrupt access to critical technological imports (e.g., semiconductors, critical minerals).
  • FDI Diversion: Reallocation of global capital toward geopolitical allies via “friend-shoring” limits India’s foreign direct investment inflows.
  • Weakened Dispute Redressal: The persistent paralysis of the WTO Appellate Body removes institutional shields against arbitrary, developed-world trade barriers.

2. Strategies to Meet the Challenges

  • Agile Bilateral Integration: Fast-track comprehensive, fair Free Trade Agreements (FTAs) with strategic partners (e.g., India-UAE CEPA, Australia ECTA).
  • Domestic Resilience: Boost manufacturing competitiveness and reduce critical import dependencies through targeted subsidies (e.g., PLI Scheme, National Logistics Policy).
  • Capitalizing on ‘China+1’: Rapidly improve infrastructure and contract enforcement to attract shifting Global Value Chains (GVCs).
  • Plurilateral Coalitions: Champion Global South interests and actively engage in issue-based, flexible economic frameworks (e.g., IPEF supply chain pillar).

By blending internal structural resilience (Atmanirbhar Bharat) with agile, pragmatic bilateral diplomacy, India can effectively transform this deglobalization wave into a strategic economic opportunity.

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:

Published by the UNDP, HDI measures average achievements in health, education, and income, whereas IHDI discounts these averages to account for inequality.

1. Distinguishing HDI and IHDI (Indian Context)

  • Measurement Approach: HDI calculates average national achievements, while IHDI applies Atkinson’s inequality measure to penalize disparities.
  • Development Perspective: HDI reflects “potential” human development; IHDI reflects the “actual” development experienced by citizens.
  • India’s Reality Check: In the UNDP HDR 2023-24, India’s HDI is 0.644, but its IHDI sharply falls to 0.444.
  • Inequality Penalty: This 0.200 drop signifies a severe ~31.1% loss in India’s overall human development due to structural inequalities.

2. Why IHDI Better Captures Inclusive Growth

  • Unmasks Skewed Averages: Prevents outlier wealth from masking mass deprivation (Oxfam: Top 1% hold 40% of India’s wealth).
  • Highlights Distributional Inequity: Accurately tracks unequal grassroots access to essential healthcare and quality education (urban-rural divides).
  • Real Capability Assessment: Reflects the true standard of living experienced by the bottom pyramid, moving beyond per-capita illusions.
  • Drives Equitable Policy: Shifts governmental focus from aggregate GDP growth to targeted redistribution mechanisms (DBT, MGNREGA).

Integrating IHDI into macroeconomic policymaking is essential for India to transition from mere aggregate growth to authentic “Sabka Saath, Sabka Vikas”, directly advancing SDG 10 (Reduced Inequalities).
