Climate Change Risk Assessment in the Indian Himalayan Region

A study conducted by researchers at the Indian Institute of Technology (IIT) Madras reveals significant differences in climate change-induced risk between the Western and Eastern Indian Himalayan regions. Published in the International Journal of Disaster Risk Reduction, the study assesses 109 administrative districts using Intergovernmental Panel on Climate Change (IPCC) criteria.


The Western Himalayan Region faces higher overall risk, with two-thirds of its districts falling into high-risk categories, primarily due to elevated hazards and exposure. Conversely, the Eastern Himalayan Region exhibits lower risk, with most districts categorized as low or lowest risk.

Aayush Shah, a Research Scholar at IIT Madras, highlights that while the Eastern region is highly vulnerable, lower hazard and exposure indices mitigate risk. Notably, Himachal Pradesh's Shimla emerges as the most hazard-prone district, while Kiphire, Nagaland, faces the least hazards.

Using IPCC methods and multiple data sources ensures the index's reliability and international acceptance. Krishna Malakar, Assistant Professor at IIT Madras, emphasizes the study's importance for policymakers and disaster managers in designing effective climate resilience strategies for the Himalayan region.
