LHASKarnali: prototype web app aids landslide responses

07 Feb 2024

The Hindu Kush Himalaya is one of the most fragile and hazard-prone mountain regions in the world. Landslides pose major disasters in the region, including Nepal, with significant impacts due to their high frequency, substantial financial costs, and adverse effects on the population and socioeconomic activities.

With over a billion people at risk, the increasing frequency and intensity of natural hazards in this region is a growing concern. Annually, Nepal experiences the destructive aftermath of landslides, causing the loss of buildings, agricultural land, forests, roads, hydropower projects, and public infrastructure, with an average of 200 fatalities.

To enhance the understanding of landslide hazards in Nepal, a web application called LHASKarnali (Landslide hazard awareness system for Karnali River Basin, Nepal) was developed. This was a collaborative effort between ICIMOD, NASA Goddard Space Flight Center landslides team, National Disaster Risk Reduction and Management Authority (NDRRMA) and several other national stakeholders. The innovative tool provides estimates of landslide hazards with a foresight of up to one day in advance, contributing to improved disaster preparedness and response initiatives in the region. The integration of LHASKArnali’s information and data provided with other social and infrastructure information further enables effective disaster response efforts and informed decision-making processes.

LHASKarnali was adapted from the Landslide Hazard Assessment for Situational Awareness version 2, incorporating the High-Impact Weather Assessment Toolkit (HIWAT) Forecast.
