Abstract

Coastal areas have very important roles andbenefits. Unfortunately, most of them in the world areexperiencing the effects of climatic changes such as rising sealevels, increasing coastal erosion, and marine intrusion.Meanwhile, there have been many studies on coastalvulnerability from various aspects and perspectives. Therefore,it is necessary to study the trend on coastal vulnerability frompast historical records of several decades ago and also from theaspects that have not been studied. This study aims to identifygaps and opportunities related to coastal vulnerability toprovide solutions to sustainability themes in the future. Also,there is a need for this study since it is not monotonous andcontains a novel element. The method used in this review articleis Web of Science (WoS) as the database source, whileVOSviewer is used to visualize and analyze the Bibliometricmaps. WoS is a website that provides subscription-based accessto multiple databases that provide comprehensive citation datafor many different academic disciplines, while VOSviewer is asoftware tool for constructing and visualizing bibliometricnetworks. The analysis shows that for over 20 years, topicsrelated to coastal vulnerability around the world are dividedinto four categories, each of which shows the most frequentlyoccurring themes, namely climate change, coastal vulnerability,sea level, and vulnerability. Subsequently, there is a gap incoastal vulnerability, which is a topic on climate change that hasbeen rarely studied in Indonesia since 2015. This bibliometricapproach is used to identify key themes in each study or scope ofknowledge that has been conducted so far, which is beneficialindetermining novel future research.
