A water risk index for portfolio exposure to climatic extremes: conceptualization and an application to the mining industry

Luc Bonnafous, Upmanu Lall, and Jason Siegel
Short summary
While water-risk management plans for economic assets are the norm on a local basis, it is possible that there is correlation in the climate induced portfolio water risk across operational sites. Therefore, from an investor's perspective, a need exists for a water risk index that allows for an exploration of the possible space and/or time clustering in exposure across many sites. This paper represents an attempt to develop such an index using long daily global modelled rainfall data sets.
