Landslide Study on Sino-Nepal Road Corridors

Belt and Road initiatives aims to promote peaceful economic development however these initiatives may clash
with the environmental condition because of the expansion and upgrading of transportation infrastructure in
environmentally sensitive areas. Most of the economic road connectivity passes through very high mountains and
unstable slopes in the Belt and Road countries. Therefore, a better understanding of mountain slopes with the
distribution of natural hazards area always important for sustainable infrastructure development and avoid placing
infrastructure in unstable and vulnerable slopes. In this context, China will be connected to Nepal with three
main trans-Himalayan roads namely: Gyirong-Rasuwagadhi-Kathmandu, Jhyangmu-Tatopani-Kathmandu, and
Korala-Jomsoom-Pokhara. These proposed road connectivities will pass through the high Tibetan Plateau with
rugged and fragile Himalayan mountain slopes where people are suffering different kinds of natural hazards and
losing many lives and properties.

A detailed field study was carried out in the Korala-Jomsoom-Pokhara road corridors which descends from Kora
la (4660m) pass between China and Nepal along the Kaligandaki River and connect Pokhara (1400 m) in western
Nepal. The road passes the steep and fragile mountain slopes where Himalaya is acting topographic barrier and
thus resulting two different kinds of landscapes with different kinds of natural hazards.
