Water in India: Overview, Challenges, and Solutions
India is a water-rich country in terms of total freshwater resources, but uneven distribution, pollution, and overexploitation have led to severe water scarcity in many regions. Here’s an in-depth look at water in India:
1. Water Resources in India
India receives about 4% of global precipitation but supports 18% of the world’s population. Key sources include:
- Rivers (Ganga, Yamuna, Brahmaputra, Godavari, Krishna, etc.)
- Groundwater (largest source for irrigation & drinking)
- Rainfall (Monsoon-dependent, ~70% of annual rain in 4 months)
- Lakes, Ponds & Reservoirs (e.g., Chilika Lake, Dal Lake, Bhakra Dam)
- Glaciers & Snowmelt (Himalayan rivers like Indus, Ganga, Brahmaputra)
2. Major Water Challenges in India
A. Water Scarcity
- Per capita water availability has declined from 5,177 m³ (1951) to ~1,486 m³ (2021) (approaching “water-stressed” levels).
- Drought-prone regions: Rajasthan, Maharashtra, Karnataka, Tamil Nadu.
- Over-extraction of groundwater: India extracts 25% of global groundwater (more than USA & China combined).
B. Water Pollution
- Industrial waste (textiles, tanneries, chemicals) contaminates rivers (e.g., Yamuna, Ganga).
- Agricultural runoff (pesticides, fertilizers) pollutes groundwater.
- Urban sewage: Only 30% of wastewater is treated before disposal.
C. Uneven Distribution
- Floods in Assam, Bihar vs. droughts in Maharashtra, Rajasthan.
- Inter-state water disputes (Kaveri, Krishna, Godavari, Ravi-Beas).
D. Climate Change Impact
- Erratic monsoons, melting glaciers, and rising temperatures worsen water stress.
3. Government Initiatives & Solutions
A. Key Government Schemes
- Jal Jeevan Mission (JJM) – Provide tap water to every rural household by 2024.
- Namami Gange Programme – Clean & rejuvenate the Ganga River.
- Atal Bhujal Yojana – Sustainable groundwater management.
- National Water Mission – Improve water use efficiency.
B. Water Conservation Efforts
- Rainwater Harvesting (Mandatory in many states like Tamil Nadu).
- Watershed Management (e.g., Ralegan Siddhi model by Anna Hazare).
- Community-led initiatives (e.g., Tamil Nadu’s Kudimaramathu for tank restoration).
C. Technological & Policy Solutions
- Smart Water Meters (to reduce wastage).
- Desalination Plants (in coastal areas like Chennai).
- Wastewater Recycling (e.g., Delhi’s Barapullah Drain treatment).
4. Future Outlook
- By 2030, India’s water demand may double, leading to severe shortages.
- Sustainable agriculture (drip irrigation), stricter pollution control, and better urban planning are needed.
- Public awareness (e.g., “Save Water” campaigns) is crucial.
Conclusion
India faces a water crisis due to mismanagement, pollution, and climate change, but solutions like rainwater harvesting, wastewater treatment, and policy reforms can help secure water for future generations.
