Water Risk Indices

A Review of Water Scarcity Indices and Methodologies

In the past 20 years many indices have been developed to quantitatively evaluate water resources vulnerability (e.g. water scarcity or water stress).  The difficulty of characterizing water stress is that there are many equally important facets to water use, supply and scarcity.  Selecting the criteria by which water is assessed can be as much a policy decision as a scientific decision.  This review provides an overview of the primary water scarcity indices and water resource assessment methodologies at the forefront of political and corporate decision making.

The Sustainability Consortium helped fund this project.
