Abstract

The production of metal commodities is often dependent upon access to water resources, particularly during the initial mining and mineral processing stages of production where the majority of water is typically used. Given that different metals are sourced from mines operating in different regions, the relative water supply risk facing individual metals will differ.
Recent advances in water footprinting methodology have resulted in a variety of spatial indicators for water scarcity and stress being available. Different indicators assess these issues from different perspectives, such as assessing the level of competition for water resources in a given area or relating the impact of water consumption to the long-term availability of water in a given area. Mapping the location of metal ore mining and processing against these various indicators provides some insight into which metal commodities are potentially at risk from water supply related issues.
