“…The mathematical calculation of the CVI is generated by combining a defined number of variables or parameters by means of an equation (Equation (1)), which combines the relative risk variables to create a single indicator. The first step involves creating a database with the variables to be considered, where the literature review shows that the number of variables can range from five to ten [24], but what is essential in the analysis of variables is that they are able to describe the coastal evolution from the geological and hydrodynamic point of view [21]. In this case study, six variables were considered, weighting geomorphology, coastal slope, mean sea level, shoreline displacement or coastal erosion, tidal range, and wave height.…”

The coastal zone of the Valparaíso Region has been historically threatened by its natural and anthropogenic conditions, which demands efficient management for the adaptation and mitigation of the impacts that occur on the coast, especially in the face of the growing effects of climate change. As a contribution to decision makers in the development of strategic actions through adaptation plans, this study presents an approach to coastal vulnerability in the southern part of the region, applying the Coastal Vulnerability Index considering the variables geomorphology, coastal slope, changes in sea level, coastal erosion, tidal range, and wave height. The result illustrates a sectorization of the coast according to the degree of vulnerability, where the sectors formed by fine sandy beaches near river mouths and estuaries present greater risks to climatic events than those rocky stretches with medium-low cliffs.

“…The CVI is considered the best method in vulnerability assessment because of the combination of many influencing factors [43]. Obligatory variables for the assessment are the parameters of geomorphological conditions-relative elevation, landforms [36], coastal embayment, beach shape [44], and coastal geomorphology [45]. Geology-coastal vulnerability is geologically dependent and requires regional assessments [33], including contemporary exogenous processes, such as shoreline displacement [36], lithodynamic beach elements [44], geomorphological processes [46], coastal processes [47], and erosion vulnerability assessment in delta [30].…”

“…However, we used the data of the increase of the relative level of the lake during the surge phenomena, which occurred as a result of the strongest winds, with gusts of up to 60-70 m/s [35]. At the same time, scientists recommend covering all aspects of coastal zone evolution when choosing the input parameters for a CVI estimation [44]. To determine the relief of coast parameter data, 1:200,000 scale topographic maps, 1:200,000 scale geomorphological maps of the Alakol Lake coast, and 5 m interval horizons extracted from the SRTM digital elevation model were used.…”

“…For example, the CVI for a section of the coast of the alluvial-industrial plain on the cones of the removal of the Tentek, Zhamanthy, and Yrgaity rivers (southwestern coast) was designed according to the scheme √ (2 × 2 × 2 × 3 × 4 × 1)/6, and amounted to 4 points. After applying the Gornitz formula, the numerical value of coastal vulnerability was divided into four categories depending on the natural discontinuities by the method provided by the ArcGIS software [44]. Based on the results, a map was built.…”

Over the last few decades, increasing water levels of Lake Alakol have led to the activation of processes of modern relief formation of the coastal territory. This study will make it possible to assess the vulnerability of the lake shore to modern relief-forming processes, which pose a threat to the economic and infrastructural development of the coast. Through a combination of field research methods, analysis of the archival materials and satellite images, GIS mapping, as well as the application of the Coastal Vulnerability Index, developed by Gornitz, a map of the modern relief of the coast of Lake Alakol was created, where 13 geomorphological types of relief were identified, and a map of relief-forming processes and leading exogenous processes were identified. The values of the assessment of the degree of vulnerability of the coast to dangerous processes by the Gornitz method were obtained, where a high vulnerability covers 67.4% of the coast, an average vulnerability covers 2.9%, a weak vulnerability covers 13.3%, and low vulnerability occupies 16.4% of the coast. The degree of vulnerability of types of relief in the study area, the coast of Lake Alakol, was determined. High degree occupies 42.8% of the study area, medium—30.7%, weak—25.4%, and low 1.1%. A map of the complex assessment of the degree of vulnerability of the coast of Lake Alakol was created. It was revealed that low accumulative types of relief of the northwest and northeast coasts and alluvial-proluvial types of relief are highly vulnerable due to waterlogging and the intensity of abrasion processes. Identified natural features of the relief formation of the coast of Lake Alakol are recommended as a basis for making decisions on the planning and implementation of any economic activities on the coast, including infrastructure development of the coast and strengthening of the shores.

The concrete damages of climate change are intensifying, and adaptation efforts of actors around the world are increasing, especially in coastal regions. Recommending adaptation measures for specific regions and sectors and determining long-term strategies for mitigating global climate change is essential for reducing vulnerability to climate change. This research aims to estimate the changes in climatic parameters and thermal comfort zones to determine concrete targets and offer suggestions for sectors affected by possible changes. The changes that will occur until 2100 in the Antalya basin, which is located in the southernmost part of Türkiye and is a significant hub for agricultural production and tourism, were monitored spatially using Discomfort Index (DI) and Effective Temperature taking wind velocity (ETv). The Shared Socioeconomic Pathways (SSP): SSP 245 and SSP 585 predict that the quite cool areas prevailing in the area, according to ETv, will shrink by 24% and 46%, respectively, and the prevailing cold areas, according to DI, will shrink by 45% and 56%, respectively. By 2100, 5% of the area, according to SSP 245, and 25%, according to SSP 585, will turn into hot areas and move away from the comfort level. The fact that critical regions are areas with high vitality in terms of coastal tourism shows the need to prioritize adaptation policies. These discoveries are discussed in the context of critical issues such as water scarcity and food security, contributing to policy-making for effective management by suggesting specific adaptation measures.
