UPSC Previous Year Question | Mains GS1 | 2024

The groundwater potential of the Gangetic valley is on a serious decline. How may it affect the food security of India? (Answer in 250 words)

Answer

Introduction

Introduction

The alluvial Gangetic basin is a major groundwater-dependent agricultural region; declining aquifer potential threatens the reliability and affordability of food production.

Agricultural Impacts

Impact on agriculture

  • Reduced irrigation reliability can lower yields of wheat, rice, sugarcane and vegetables and increase crop failures during monsoon variability.
  • Deeper pumping raises energy and cultivation costs, hurting small and marginal farmers first.
  • Farmers may shift from foodgrains to less water-intensive or higher-value crops, affecting procurement and buffer stocks.
  • Water quality deterioration, including arsenic in parts of the basin, creates health and productivity risks.

Food Security Dimensions

Food-security consequences

  • Lower output can increase prices, imports and pressure on the Public Distribution System.
  • Reduced farm income worsens nutrition, rural employment and indebtedness.
  • Over-extraction creates a feedback loop: water scarcity, distress migration and weaker capacity to invest in conservation.

Response

Way forward

  • Adopt aquifer-based regulation, metering and community water budgets.
  • Promote less water-intensive crops, direct-seeded rice, micro-irrigation, soil-moisture conservation and treated wastewater reuse.
  • Reform power incentives, expand recharge and protect wetlands while sustaining food buffers through climate-resilient procurement.
