As a reaction to the expanding challenges associated with social susceptibility and their interconnection to diverse environmental threats, parametric insurance plays a key role as an innovation tool in the insurance sector to enhance social resilience to natural disasters and extreme climatic conditions, which can tremendously impact several economic sectors, including agriculture and as a result food security. In this context, this study investigates the association between rainfall Gini index and drought events in Northern Europe. For this purpose, we acquired ERA5 data for daily precipitation for five locations from 1980 to 2022. Gini Index (GI) values were calculated and analyzed for each location with the Mann-Kendall test at a 5% significance level. As expected, a minimal decreasing trend has been observed for daily precipitation, while an increasing trend was recorded for Gini Index. In addition, data on the Soil Moisture Index (SMI) and top drought events were extracted from the European Drought Observatory (EDO) to explore their potential association with the Gini index over time and space. Although a moderately low to negligible correlation, ranging between -0.27 and 0.02, was found between SMI and GI, a qualitative comparison between major drought episodes and Gini index anomaly showed that similar spatiotemporal patterns are present across the region, particularly for extreme drought events in 1996-1997 and 2003. The current study elucidates the rainfall Gini Index's efficiency as a drought indicator for qualitative analysis, yet more work must be conducted to quantitatively evaluate its association with drought magnitude.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
