A call for an accurate presentation of glaciers as water resources

Abstract

Glaciers are often portrayed as an important water resource in scientific research and public debate. However, the scientific literature calls for caution when presenting this idea. While melting glaciers can increase water insecurity, their contribution to runoff is often minor and other factors like excessive groundwater pumping for irrigation or surface and groundwater contamination pose much greater threats to water availability. As we consider the wide range of environmental impacts due to glacier changes, we must also question the “glacier as water resource” narrative that may unnecessarily contribute to public anxiety.
