This map story lists glacial lakes of Nepal that have been categorized as potentially dangerous based publication - "Glacial Lakes and Glacial Lake Outbrust Flood in Nepal", published by ICIMOD in 2011.
READ MOREThis story map allows users to visualize the changes of Imja Glacial lake using a time-slider tool from 1992 to 2009 as well as it provides the basic information,charts and statistics about Imja Lake.
READ MOREHigh levels of water-induced erosion in the transboundary Himalayan river basins are contributing to substantial changes in basin hydrology and inundation. Basin-wide information on erosion dynamics is needed for conservation planning, but field-based studies are limited. This study used remote sensing (RS) data and a geographic information system (GIS) to estimate the spatial distribution of soil erosion across the entire Koshi basin. The revised universal soil loss equation (RUSLE) was used in an ArcGIS environment with rainfall erosivity, soil erodibility, slope length and steepness, cover-management, and support practice factors as primary parameters. The estimated annual erosion from the basin was around 42 million tonnes.

The application carries out all the analyses or geo-processings in Google Earth Engine, the Google’s cloud based platform, except for species occurrence data which are obtained directly from Global Biodiversity Information Facility (GBIF).
READ MOREThe application showcases changes in the glaciers in Afghanistan from 1990 to 2015. The interactive glacier maps were prepared for 1990, 2000, 2010, and 2015 using a uniform data set and methodology, which provide a scientific basis for understanding the changes taking place in the glacial environment in the Himalayas of Afghanistan.
