Popis: The occurrence of landslides in the Nepal Himalaya is a common phenomenon due to active seismotectonics coupled with the strong monsoon, fragile landscape, and inadequate agricultural practices. This research has analyzed the trends of landslide events, total fatalities, and economic losses from 1971 to 2016 and discussed the landslide early warning system initiatives in Nepal. Spatiotemporal variation of landslide events shows an increasing trend with nonlinear relationships between events and deaths. The highest number of events and fatalities is concentrated in central Nepal due to population growth, rural-urban migration, and haphazard road construction. Moreover, the number of deaths and economic loss is higher in the hills compared to the mountain and Terai. Only few early warning system initiatives were applied either in project or community basis in Nepal. Most of those initiatives vanished after the project completion. Nepal government should start to build a nationwide dynamic landslide inventory database system connected with weather stations for the monitoring and forecasting of the landslide.
