“…In addition to the uncertainties in the determination of the current CVI for Rhodes, the estimation of the corresponding CVI for the upcoming decades was based on more precarious 'assumptions', derived from disparate and doubtful data sources and characteristics that may have significantly affected the reliability of the final scores. Dissimilar information of diverse spatial and temporal resolution, obtained from an amalgam of field surveys, remote sensing analyses and outputs of numerical models, has probably decreased the credibility of the CVI projected to 2100 [120].…”

The foreseeable acceleration of global sea level rise could potentially pose a major threat to the natural charm and functional integrity of the world-renowned tourist coastal attractions of Rhodes Island, as a result of the anticipated increasing frequency of flooding and erosion events. Hence, this study aims to determine the most vulnerable segments (in terms of physical impact) of the Rhodes coastline through the widely accepted coastal vulnerability index (CVI), applying a combination of well-known, broadly used approaches and methods. The frequency distribution of the current CVI along the island’s coastline suggests a rather worrying high to very high vulnerability of 40%. In addition, a CVI projection to the end of the 21st century (based on the Intergovernmental Panel on Climate Change predictive scenarios) indicates an enhancement of the total vulnerability by 48%, mainly focused on the majority of the western coastline. Hence, a considerable number of popular coastal destinations in the island shall remain under unignorable threat and, therefore, coastal managers and decision-makers need to hatch an integrated plan to minimize economic and natural losses, private property damage and tourism infrastructure deterioration from flooding and erosion episodes, which will most likely be intensified in the future.

“…Kerentanan pesisir dapat disebabkan secara alami seperti pengaruh meteorologi oseanografi (met-ocean) seperti angin, pasang surut, gelombang, gelombang badai, tsunami, bencana alam seperti banjir bandang, dan curah hujan yang tinggi. Selain faktor alami, aktivitas manusia, kepadatan penduduk yang tinggi dan sistem sosial ekonomi yang besar serta kegiatan antropogenik seperti pembangunan struktur pantai secara terus menerus juga dapat menjadi faktor yang menyebabkan tingkat kerentanan suatu kawasan pesisir menjadi tinggi (Kumar & Kunte 2012;Islam et al 2016;Chandrasekar 2013;Mahmood et al 2020;Rajasree & Deo 2020;Reiners & Driese 2001;Yin et al 2012).…”

Wilayah pesisir sangat unik, dinamis, dan kompleks karena merupakan zona interaksi antara daratan, lautan, dan atmosfer. Hal ini menjadikan wilayah pesisir sebagai wilayah yang paling rentan di Bumi. Untuk mengetahui seberapa besar kerentanan di suatu wilayah pesisir, perlu dilakukan penelitian untuk mengetahui tingkat kerentanan wilayah pesisir dan faktor yang mempengaruhi. Penelitian mengenai tingkat kerentanan pesisir di lokasi ini pernah dilakukan pada tahun 2016 dan diperoleh simpulan bahwa tingkat kerentanan pesisir berada pada kategori sedang. Dengan semakin berkembangnya pemanfaatan potensi di daerah tersebut maka dirasa perlu dilakukan penelitian serupa dengan tahun 2016 untuk mengetahui apakah terdapat perubahan tingkat kerentanan antara tahun 2016 dengan tahun 2020. Data-data yang digunakan terdiri dari Data-data yang digunakan terdiri dari geomorfologi pantai, pasang surut, citra satelit Landsat 7 ETM+ dan 8 OLI, kenaikan muka laut dan DEM. Analisis data menggunakan metode Coastal Vulnerability Index (CVI). Hasil penelitian menunjukkan tingkat kerentanan pesisir di lokasi penelitian berada pada kategori rendah-sedang, dengan kisaran skor CVI 9,93-25,86. Topografi, geomorfologi, intensitas perubahan garis pantai, dan kemiringan pantai merupakan faktor yang dapat menyebabkan tingkat kerentanan di lokasi penelitian menjadi sangat tinggi. Namun, keterhubungan antara parameter lain yang dapat menjadi faktor penghambat tingginya tingkat kerentanan, menyebabkan tingkat kerentanan pesisir di lokasi penelitian hanya berada dalam kategori rendah-sedang. Terdapat perubahan kondisi tingkat kerentanan antara tahun 2016 dengan tahun 2020 dimana pada tahun 2020 tingkat kerentanan di pantai timur mengalami penurunan menjadi kategori rendah.

“…Index‐based approaches for assessing coastal vulnerability, such as Coastal Vulnerability Index (CVI), provide vulnerability measures in a quantitative manner. Alternatively, there have been other approaches, such as Geographic Information System (GIS)‐based decision support or dynamic model outcomes that include flood hazard models and continuous remote sensing observation to represent the coastal regions' vulnerability characteristics (Rajasree & Deo, 2020). The index‐based vulnerability assessment approach continues to be widely used, as its application and visualization are easy, and it considers a variety of vulnerability‐related indicators for the final assessment.…”

Coastal regions contribute tremendous economic benefits, including tourism, trade, ports, transportation, and aquaculture to the local and national economy. Currently, approximately 40% of the global population resides in coastal regions with less than 60 km of distance from the coastlines (Small & Nicholls, 2003). However, coastal systems are exposed to numerous natural hazards, including severe floods, storm surges, hurricanes, nuisance flooding, extreme heat waves, and winds. In addition, the frequency and magnitude of these events are increasing with climate change, which, in turn, causes adverse consequences on coastal socio-environmental systems. Increasing CO 2 emissions and temperature have a direct impact on hurricane activities, strongly weighted to the high frequency of hurricane activities (Emanuel & Center, 2020;Vecchi et al., 2019). Increasing trends of greenhouse gas emissions, sea level rise (SLR), and sea surface temperature in densely populated coastal areas are found to be the main factors of increasing coastal hazards over the past decades (Gornitz, 1990), which, unfortunately, is expected to continue. Since 1998, the USA has experienced approximately 18 of its most costly hurricanes (out of 20), which have resulted in more than $800 billion economic damages (NOAA, 2023). Just in 2017, three devastating hurricanes, Irma, Harvey, and Maria, together resulted in more than $50 billion of damages in the USA (NOAA, 2020). In addition, the coastal flood's nature and storm responses have been rapidly changing with tide non-linearity, extreme wave height, short-term ocean climate variability, beach erosion, and cliff retreats (Barnard et al., 2019;. At the end of the 21st century, SLR can profoundly change the coastline of the USA, and in turn, exponentially increase the coastal flood frequency due to SLR (Taherkhani et al., 2020). Increasing coastal hazards emphasize the need for more comprehensive and informative vulnerability assessments and measures, particularly the need to represent the socio-environmental dimension in assessment, which is currently more prominent. Inclusion of Socio-Economic Dimensions in Vulnerability AssessmentThe nexus between the vulnerability of hazard drivers and the vulnerability from socio-economic components is often difficult to study and assess. Coastal vulnerability spatial variation is of particular importance since it helps
