Landslides and Climate Risks Threaten India's Mountain Roads
Landslides and Climate Risks Threaten India's Mountain Roads
IN · Published Oct 22, 2026
• Frequent landslides, exacerbated by heavy rainfall and road construction, are increasingly disrupting travel in India's mountainous regions, particularly in the Himalayas.
• A study published in March 2025 identified high and very high landslide susceptibility zones along an 80-km stretch from Karnaprayag to Joshimath in Uttarakhand.

Impact & Risks

Landslides pose significant risks to travellers, local communities, and infrastructure in the Himalayan region. Roads such as National Highway 7 and others in Kashmir, Sikkim, and Manipur have been flagged for slope instability. The risks are heightened during monsoon seasons, with 81% of landslides occurring within 100 metres of under-construction roads. These events disrupt connectivity, isolate communities, and increase the likelihood of accidents. Additionally, poorly designed roads and bridges can exacerbate flooding and erosion, further endangering lives and property. The economic costs of repairing damaged infrastructure and the environmental impact of construction activities also remain significant concerns.
