🔆 Melting Himalayan Glaciers: Cascading Effects on India’s Water Resources
(UPSC 2020, 2013)
✅ Accelerated glacial melt, driven by climate change, threatens India’s water security
✅ Himalayan glaciers feed Ganga, Brahmaputra, Indus – vital for agriculture, hydropower, and drinking water
✅ Initial melt may cause flooding (e.g., Uttarakhand 2013)
✅ Long-term effects: reduced river flows during dry seasons
✅ May trigger:
• Water shortages
• Crop failures
• Interstate water conflicts
• Decline in groundwater recharge, esp. in Indo-Gangetic Plain
• Disrupted monsoons → strain on water systems
🔁 Urgent need for:
➡️ Sustainable adaptation strategies
➡️ Efficient water management practices
