WATER INSECURITY
India is facing an increasing challenge of water insecurity due to climate change, rapid urbanisation, inefficient water management, and declining groundwater resources. Discuss the major challenges to achieving water security in India. Suggest suitable measures to build a climateresilient and water-secure future.
Model Answer
Introduction
- Water Security means ensuring adequate quantity and quality of water for people, agriculture, industries, and ecosystems.
- India is witnessing increasing water stress, with 11 out of 15 major river basins under stress and several cities facing severe water shortages.
Major Challenges to Water Security
- Climate Changeà Erratic monsoon and frequent droughts, Increased floods and extreme weather events.
- Rising Water Demandà Population growth, rapid urbanization, industrial expansion.
- Groundwater DepletionàExcessive extraction for irrigation and domestic use, Falling groundwater levels in many regions.
- Poor Water InfrastructureàHigh transmission and distribution losses, Poor maintenance of pipelines and reservoirs.
- Water Pollutionà Untreated sewage and industrial effluents, Contamination of rivers, lakes, and groundwater.
- Inefficient Agricultural Practicesà Flood irrigation leading to wastage, low adoption of drip and sprinkler irrigation.
- Weak Water Governanceà Lack of river basin-level data, poor coordination among agencies, limited wastewater reuse.
Measures to Build Water Security
Improve Water Infrastructure
- Climate-proof reservoirs and urban drainage.
- Modernise distribution networks.
Promote Water Reuse
- Treat and reuse wastewater for industries, construction, landscaping, and agriculture. Expand Micro-Irrigation
- Promote drip and sprinkler irrigation.
- Encourage low-water, high-value crops.
Strengthen Data and Technology
- AI-based monitoring.
- Smart water meters.
- River basin-level water accounting.
Integrated Water Resource Management (IWRM)
- Conjunctive use of surface and groundwater.
- Community participation.
- Rainwater harvesting and watershed management.
Conclusion
Achieving water security requires scientific planning, climate-resilient infrastructure, efficient water use, technological innovation, and transparent governance. A sustainable and integrated approach will help India ensure long-term water security, support economic growth, and achieve SDG 6 (Clean Water and Sanitation).
