Disaster Resilient Infrastructure: A Bibliometric Analysis of Global Research Trends

Abstract

The vital role of infrastructure in the delivery of essential services and the severity of disasters globally calls for more research and discourse on disaster resilient infrastructure. Despite the increasing body of knowledge on disaster resilient infrastructure, an assessment of research on the subject is lacking. This study fills this gap by assessing the global research trend in disaster resilient infrastructure. The study adopted a bibliometric analysis with the use of the VOSviewer. The main search words used in the study were “Disaster”, “Resilient”, AND “Infrastructure. Initial extracted papers with these keywords were 1041. After refining based on language, document type, and key words, a total of 278 papers were found suitable for the analysis. The years 2020 to 2022 indicated the highest research outputs while countries with highest number of publication on the subject of disaster resilient infrastructure were the United States, United Kingdom and Japan. Most of the highly cited works were review-based, case studies and a few experimental. The findings of this study serve as a source of baseline data on disaster resilient infrastructure which can provide new research directions and also guide the design and implementation of policies on disaster-resilient infrastructure.
