Background

Overview

Water security is fundamental to India's economic development, food security, public health, and environmental sustainability. UPSC frequently asks about challenges and solutions related to water resources, inter-state water disputes, and government initiatives and policies.

India, home to 18% of the world's population but only 4% of its freshwater resources, faces chronic water stress due to uneven distribution, over-extraction, pollution, and climate change impacts. Sustainable water management involves adopting holistic strategies to ensure equitable access, efficient use, and conservation of water resources for present and future generations.

Facts & tables

Key facts

River Basin Stress

11 out of 15 major river basins in India are experiencing water stress (annual availability below 1,700 m3 per person).

Water Scarcity Threshold

Several basins (Krishna, Cauvery, Mahi, Tapi) are below the water scarcity threshold (1,000 m3 per person).

Infrastructure Gaps

Concerns remain regarding poor upkeep of existing infrastructure, inadequate wastewater treatment, and substantial conveyance losses.

Micro-irrigation Coverage

Micro-irrigation systems cover only 20% of India's potential 72 million hectares of irrigated area.

Quick revision

  • India faces severe water stress; 11/15 major river basins stressed, many below scarcity threshold.
  • Key challenges: infrastructure gaps, pollution, aquifer depletion, climate change impacts (e.g., El Nino).
  • Proposed solutions: climate-proofing water systems, promoting urban water reuse (circular economy).
  • Agricultural focus: scaling micro-irrigation, crop diversification, robust insurance (PMFBY).
  • Critical need for improved basin-level water data, smart metering, and AI-based monitoring.

Elimination traps

Authority vs ministryDistinguishing between research bodies (like CEEW) and implementing government agencies or ministries, or between specific missions/schemes and the broader policy framework.

Ministry sets policy; regulator often has quasi-judicial powers.
