Nepal is characterized by towering mountain ranges and deep valleys of the Himalayan region; the country is prone to geohazards such as earthquakes, landslides, floods, droughts, and glacial lake outburst floods (GLOFs). These disasters can pose significant risks to human lives and infrastructure. As a developing nation with limited resources, Nepal faces challenges in implementing effective disaster prevention and response measures. This paper explores the use of state-of-the-art remote sensing technologies tailored to Nepal’s geo-disaster management needs and presents case studies on using advanced techniques like Light Detection and Ranging (LiDAR), Unmanned Aerial Vehicles (UAVs), Synthetic Aperture Radar (SAR), and multispectral satellite images. The potential use of these techniques in the Nepalese context for different geohazards is discussed. By demonstrating these tools, technical capabilities and cost-effectiveness, the study aims to help policymakers and disaster management agencies in Nepal develop proactive and efficient strategies to mitigate geohazards, minimize risks, and improve resilience.

摘要

Nepal is characterized by towering mountain ranges and deep valleys of the Himalayan region; the country is prone to geohazards such as earthquakes, landslides, floods, droughts, and glacial lake outburst floods (GLOFs). These disasters can pose significant risks to human lives and infrastructure. As a developing nation with limited resources, Nepal faces challenges in implementing effective disaster prevention and response measures. This paper explores the use of state-of-the-art remote sensing technologies tailored to Nepal’s geo-disaster management needs and presents case studies on using advanced techniques like Light Detection and Ranging (LiDAR), Unmanned Aerial Vehicles (UAVs), Synthetic Aperture Radar (SAR), and multispectral satellite images. The potential use of these techniques in the Nepalese context for different geohazards is discussed. By demonstrating these tools, technical capabilities and cost-effectiveness, the study aims to help policymakers and disaster management agencies in Nepal develop proactive and efficient strategies to mitigate geohazards, minimize risks, and improve resilience.
