A recent study conducted by researchers from Nagaland University and Cotton University highlights a significant glacier retreat in Arunachal Pradesh. The research, spanning over three decades, indicates a worrying decline in the number and size of glaciers in the region. This rapid change could severely impact water availability for local communities relying on glacial meltwater.

Key Findings from the Study

The study utilized Remote Sensing (RS) and Geographic Information Systems (GIS) to analyze glacier changes from 1988 to 2020. Researchers found that the total number of glaciers in Arunachal Pradesh decreased from 756 to 646 within this period. Additionally, the total glacier-covered area shrank by more than 300 square kilometres. Notably, smaller glaciers are retreating at a faster pace, exacerbating the concern over water resources.

Implications for Water Security

The glacier retreat in Arunachal Pradesh is a significant threat to water availability. Many communities depend on glacial meltwater for drinking, irrigation, and hydropower. A study commissioned by the Observer Research Foundation also highlighted that around 75% of Himalayan glaciers are retreating, leading to reduced surface and groundwater supplies. Springs, a crucial water source for hill communities, are drying up, increasing the urgency for sustainable water management strategies.

Call for Action and Monitoring

With Arunachal Pradesh losing an estimated 110 glaciers over the past 32 years, experts stress the need for continuous monitoring and policy intervention. These glaciers, mostly found at elevations between 4,500 and 4,800 meters, serve as natural freshwater reserves. Without proactive measures, villages and towns in the region may face severe water shortages in the coming years.

Conclusion

The rapid glacier retreat in Arunachal Pradesh highlights the urgent need for improved climate adaptation strategies and water conservation policies. Continuous monitoring, research, and government interventions are essential to mitigate future water crises and ensure sustainable water management in the region.
