Vulnerability assessment for loss of access to drinking water due to extreme weather events

Extreme weather events can result in loss of access to drinking water. In Climatic Change, we used five different indicator-based models to assess the relative vulnerability of 3,143 U.S. counties to loss of drinking water access due to droughts, floods, and cyclones. One model produced different results to the others, suggesting that model selection affects the results of vulnerability assessment. Identifying counties with the greatest vulnerability to loss of drinking water access provides useful evidence for decision-making on resource allocation and adaptation strategies.
