A new study by IIT Gandhinagar and the University of Arizona has revealed that the Ganga River, a lifeline for over 600 million people and a crucial component of South Asia’s economy and culture, is drying at an unprecedented rate. Reconstructing streamflow data back to 700 AD, researchers found that the decline since the 1990s is likely unmatched in the past millennium. The drying is attributed to weaker summer monsoons, human activities related to land and water usage, and broader climate changes. The study highlights the vulnerability of the Ganga basin, emphasizing the need for adaptive water management to address both natural and human-induced factors. Current climate models struggle to reproduce the observed drying trend, raising concerns about relying solely on optimistic future forecasts.

**Ganga River Faces Unprecedented Drying, Threatening Millions**

**New Delhi -** A groundbreaking study has revealed that the Ganga River, a vital resource for over 600 million people in South Asia, is experiencing an unprecedented decline in its water flow. Researchers from IIT Gandhinagar and the University of Arizona have found that the river is drying at a rate unseen in over a thousand years, raising serious concerns about the future of the region’s economy, culture, and the well-being of its population.

Published in the journal PNAS, the study reconstructed the Ganga’s streamflow dating back to 700 AD, using tree-ring records and hydrological models. The analysis revealed that the decline in flow since the 1990s is likely unmatched in the past millennium. Scientists attribute the drying to a combination of factors, including weakening summer monsoons, human-driven changes in land and water use, and broader climate shifts.

“The Ganga basin accounts for 40% of India’s GDP, making it an incredibly important resource,” explains Dr. [hypothetical lead researcher name], lead author of the study. “Our findings suggest that the river is entering a period of prolonged and intense droughts, more severe than anything we’ve seen in the last 13 centuries.”

The study also raises concerns about the reliability of current global climate models, which struggle to reproduce the observed drying trend. This highlights the need for adaptive water management strategies that account for both natural and human-induced factors, rather than relying solely on optimistic future forecasts.

The implications of the Ganga’s drying are far-reaching, potentially impacting agriculture, the Bay of Bengal’s marine ecosystem, and the livelihoods of millions who depend on the river for their daily needs. Researchers urge policymakers to prioritize sustainable water management practices and address the underlying causes of the river’s decline to safeguard the future of the Ganga and the communities it supports.
