The importance of accounting for equity in disaster risk models

R. Soden, D. Lallemant, et al.

In a groundbreaking study by Robert Soden and his team, discover how traditional disaster risk models often overlook the unique challenges faced by vulnerable groups. This research not only evaluates 69 risk assessments but also introduces a case study on the Nepal earthquake, revealing disparities that highlight the importance of integrating equity into disaster risk management.

Abstract
Current disaster risk models often fail to account for the disproportionate impact of disasters on vulnerable groups. This paper develops a typology to characterize approaches to incorporating equity into risk modeling and evaluates 69 risk assessments from major international development organizations. The study finds that only about 28% of models attempt a quantitative evaluation of differential impacts. A case study reconstructing a Nepal earthquake risk assessment demonstrates that equity-sensitive approaches uncover disparities missed by traditional methods, highlighting the need for improved equity considerations in disaster risk management.
