Ganga Drying, Indus Rising: Study Flags India's Water Security Threat

• IIT Gandhinagar study reveals contrasting trends: Indus flow up 8%, Ganga flow down 17% over four decades.
• Ganga's decline is the fastest in 1,300 years, threatening millions dependent on the river system.
• Indus rise attributed to Western Disturbances and changing monsoon patterns, though eastern tributaries like Ravi and Sutlej are declining.
• Ganga's drying is primarily due to extensive groundwater extraction for irrigation, not just reduced rainfall.
• Changes could impact the 1960 Indus Water Treaty; urgent need for irrigation reform and groundwater regulation.
