Fig. 6: Population count upstream and downstream of glacial lakes.
From: Evolving resource potential of glacial lakes with ongoing deglaciation
a, Estimated number of people living in catchments upstream (light-green bars) and in a 1-km buffer in the first 50 km downstream (dark-green bars) of all 70,862 glacial lakes mapped in 2020 (ref. 7). Bar heights show the median regional population count; vertical lines span the minimum and maximum estimate from four gridded population datasets (Methods) in 18 RGI regions, shown by semi-transparent polygons and their regional codes in the central map. Polygons show the World Continents, a dataset compiled by Esri, Global Mapping International (GMI), US Central Intelligence Agency (The World Factbook) and Garmin, provided by ArcGIS Data and Maps at the ArcGIS Hub (https://hub.arcgis.com/datasets/esri::world-continents/about). b,c, Comparison between estimated regional lake volume and population count upstream (b) and downstream (c) of glacial lakes. Points show medians; vertical lines span the minimum and maximum regional estimated population count, and horizontal lines span the 68% HDI of regional lake volumes. Numbers refer to the regional RGI codes in a. Regional sample sizes and volumes are shown in Extended Data Fig. 9. Map in a created with QGIS with data from Esri, Global Mapping International, the US Central Intelligence Agency (The World Factbook) and Garmin International, Inc., provided by ArcGIS Data and Maps at the ArcGIS Hub (https://hub.arcgis.com/datasets/esri::world-continents/about).
