In recent years, the global impact of climate change has led to an increase in the occurrence of Compound Hydrometeorological Extremes (CHE), where multiple extreme weather events occurs concurrently. These compound extremes present significant challenges to water resource management, infrastructure, agriculture, and human society. Therefore, it is crucial to understand the cascading effects of such events for enhancing resilience and adaptability in the face of a changing climate. This study presents a comprehensive bibliometric analysis to provide insights into the key trends, themes, and gaps in the existing literature, paving the way for enhanced disaster risk management and resilience planning. The Biblioshiny R-toolbox was utilized to assess bibliometric indicators using data from the Scopus database from 2002 to 2023. A total of 246 scholarly publications were selected for analysis, covering topics such as floods, droughts, heatwaves, storms, and their combinations. The bibliometric analysis revealed an increasing trend in research on CHE over the past decade, reflecting the growing recognition of their significance. Notably, a significant surge in publications occurred after 2010, with a focus on studying the interactions between various extreme events. From 2015 to 2017, the research community emphasized impact assessments of CHE on different sectors, while from 2018 onwards, the development of integrated risk assessment frameworks gained prominence. The analysis also highlighted the cascading effects of CHE on various sectors. For instance, Prolonged drought and heatwaves impact agriculture and food security. Flooding and heavy rainfall overwhelm drainage systems, disrupting water supply and causing infrastructure damage. Extreme heat and wildfires lead to habitat loss and health risks. Floods and landslides disrupt transportation and hinder trade, causing economic losses. This bibliometric analysis offers valuable insights into the current state of research on CHE. It highlights the need for a more holistic and integrated approach to understand the cascading effects of CHE. The findings can guide future research efforts, policy development, and the implementation of adaptation strategies to tackle the challenges posed by CHE in a changing climate.
