Full textAbstract:
Vulnerability impacts have increased in an unprecedented way with the effects of global warming, climate change, erosion, sea level rise, tsunami, flood, and drought—natural events that jointly cause geomorphological changes, especially in coastal zones. There are no analytical mathematical formulations under a set of assumptions due to the complexity of the interactive associations of these natural events, and the only way that seems open in the literature is through empirical formulations that depend on expert experiences. Among such empirical formulations are the Coastal Vulnerability Index (CVI), the Environmental Vulnerability Index (EVI), the Socioeconomic Vulnerability Index (SVI), and the Integrated Coastal Vulnerability Index (ICVI), which is composed of the previous indices. Although there is basic experience and experimental information for the establishment of these indices, unfortunately, logical aspects are missing. This paper proposes a Coastal Fuzzy Vulnerability Index (CFVI) based on fuzzy logic, aiming to improve the limitations of the traditional Coastal Vulnerability Index (CVI). Traditional CVI relies on binary logic and calculates vulnerability through discrete classification (such as “low”, “medium”, and “high”) and arithmetic or geometric means. It has problems such as mutation risk division, ignoring data continuity, and unreasonable parameter weights. To this end, the author introduced fuzzy logic, quantified the nonlinear effects of various parameters (such as landforms, coastal slope, sea level changes, etc.) through fuzzy sets and membership degrees, and calculated CFVI using a weighted average method. The study showed that CFVI allows continuous transition risk assessment by fuzzifying the parameter data range, avoiding the “mutation” defect of traditional methods. Taking data from the Gulf of Mexico in the United States as an example, the calculation result range of CFVI (0.38–3.04) is significantly smaller than that of traditional CVI (0.42–51), which is closer to the rationality of actual vulnerability changes. The paper also criticized the defects of traditional CVI, being that it relies on subjective experience and lacks a logical basis, and pointed out that CFVI can be expanded to integrate more variables or combined with other indices (such as the Environmental Vulnerability Index (EVI)) to provide a more scientific basis for coastal management decisions. This study optimized the coastal vulnerability assessment method through fuzzy logic, improved the ability to handle nonlinear relationships between parameters, and provided a new tool for complex and dynamic coastal risk management. Further research possibilities are also mentioned throughout the text and in the Conclusion section.

The coastal region is a strategic area that has enormous potential. Kalianda is one of the coastal areas in South Lampung which has great potential with the main activities are fisheries and marine tourism, but it is also vulnerable to physical effects. The purpose of this study was to assess the vulnerability of physical parameters and to analyze the level of Coastal Vulnerability Index (CVI) in Kalianda, South Lampung. The results showed that the vulnerability level of the Kalianda Coast based on the rate of shoreline change and geomorphological parameters were at a very high level of vulnerability. Whereas based on the parameters of the mean significant wave height, the average tidal tides and beach slope, the Kalianda Coast was at a low level of vulnerability. Overall, the results of the analysis indicated that CVI value ranged from 3.10 to 9.94, which categorized as low and medium vulnerability levels. Distribution of Kalianda coastal vulnerability level along 3.30 km (11.29%) was at low vulnerability level and along 25.98 km (88.71%) was categorized as medium vulnerability level.

Abstract. Coastal vulnerability Index (CVI), is one of the predictive approaches to coastal classification by incorporating various coastal variables. This approach is favoured in the coastal investigation as it simplifies a number of complex parameters. However, it comes greatly as to why such assessment is developed in the first place; a) to facilitate coastal management in recent coastal condition, b) to classify potential shoreline responses to future sea-level rise, and c) for management of data storage. Index development in coastal investigation is one of the present-day technique used to estimate the vulnerability of the coast and is affected by a diverse range of variables. The widespread use of contemporary technology nowadays has led to a favourable coastal component to be considered in determining coastal vulnerability and environmental risk analysis. Therefore, it must be guided by acknowledging appropriate data to be used at spatial scale of interest, the geomorphology of the area concerns and etc. USA and European countries like Northern Ireland are one of the forefront country in addressing the significance of CVI in protecting coastal area. A stepwise approach to development of CVI is discussed in detail in this paper. Besides, the potential of including coastal components based on special characteristic at particular coasts for coastal vulnerability analysis are also reviewed. CVI eventually will assist coastal communities in providing guidance for mitigation of coastal threats in future urban development.

Full textAbstract:
The coastal area of Segeri sub-district, Pangkajene and Kepulauan Regency is a zone that is prone to natural phenomena of sea level rise. The impact received due to this phenomenon is something that needs to be studied to identify the level of coastal vulnerability and project changes in coastal vulnerability in the future. This study aims to calculate the coastal vulnerability index and project changes in vulnerability in the future due to changes in factors that affect coastal vulnerability.This research was conducted in August – December 2022 in Segeri District, namely in, Bone, Bawasalo and Bonto Matene Villages. The methods or approaches used in analyzing the data are: 1) analysis of coastal ecosystems and resources, 2) analysis of the physical and social characteristics of the community, 3) analysis of the vulnerability of the coastal environment. The Vulnerability Scoping Diagram (VSD) models places exposure, sensitivity and adaptive capacity as dimensions of vulnerability. The components of the exposure dimension consist of coastal dynamics, natural disturbances and population. The components of the sensitivity dimension are the characteristics of the coast, land use, and population settlements. The dimensions of adaptability include coastal habitats and marine conservation areas. Based on the scores of each parameter on the three dimensions, the coastal vulnerability index (IKP) in the three locations is in the range of IKP values of 7.96 - 9.59 which is included in the category of moderate vulnerability. Factors that are very influential on the IKP are the dimensions of sensitivity including: erosion, waves and tides caused by oceanographic factors so that if adaptation and mitigation efforts are not carried out, it is likely that in the next 5-10 years, the level of vulnerability can become high and even very high. Adaptation efforts that can be done are strengthening the coastal border area, planting and expanding mangrove trees in the coastal area of Segeri.

Abstract. Increased frequency of natural hazards such as storm surge, tsunami and cyclone, as a consequence of change in global climate, is predicted to have dramatic effects on the coastal communities and ecosystems by virtue of the devastation they cause during and after their occurrence. The tsunami of December 2004 and the Thane cyclone of 2011 caused extensive human and economic losses along the coastline of Puducherry and Tamil Nadu. The devastation caused by these events highlighted the need for vulnerability assessment to ensure better understanding of the elements causing different hazards and to consequently minimize the after-effects of the future events. This paper advocates an Analytical Hierarchical Process (AHP) based approach to coastal vulnerability studies as an improvement to the existing methodologies for vulnerability assessment. The paper also encourages the inclusion of socio-economic parameters along with the physical parameters to calculate the coastal vulnerability index using AHP derived weights. Seven physical-geological parameters (slope, geomorphology, elevation, shoreline change, sea level rise, significant wave height and tidal range) and four socio-economic factors (population, Land-use/Land-cover (LU/LC), roads and location of tourist places) are considered to measure the Physical Vulnerability Index (PVI) as well as the Socio-economic Vulnerability Index (SVI) of the Puducherry coast. Based on the weights and scores derived using AHP, vulnerability maps are prepared to demarcate areas with very low, medium and high vulnerability. A combination of PVI and SVI values are further utilized to compute the Coastal Vulnerability Index (CVI). Finally, the various coastal segments are grouped into the 3 vulnerability classes to obtain the final coastal vulnerability map. The entire coastal extent between Muthiapet and Kirumampakkam as well as the northern part of Kalapet is designated as the high vulnerability zone which constitutes 50% of the coastline. The region between the southern coastal extent of Kalapet and Lawspet is the medium vulnerability zone and the rest 25% is the low vulnerability zone. The results obtained, enable to identify and prioritize the more vulnerable areas of the region to further assist the government and the residing coastal communities in better coastal management and conservation.

Full textAbstract:
Coastal regions are changing due to environmental pressures and anthropogenic impacts such as coastal development and planning, ultimately becoming sensitive to unpredicted natural and manmade calamities. The scientific assessment requires an understanding of the relative vulnerability of the coast across a region, and, for this purpose, vulnerability indices are often used. This study is an integrated coastal vulnerability index for the Karnataka coastline, incorporating both physical variables and socio-economic indicators. To study the overall vulnerability of a region at the taluka level using the typical physical variables characterizing coastal vulnerability e.g. historical shoreline change, rate of relative sea-level change, coastal regional elevation, coastal slope, mean tidal range, significant wave height and geomorphology. Physical indicators are then combined with the outcomes of an assessment of socio-economic vulnerability developed using population and tourist density and education as indicators like human development index (HDI), composite taluka development index (CTDI) and urban development index (UDI), resulting in a more holistic assessment of vulnerability. The resulting vulnerability map describes the taluka as most vulnerable to physical indicators and also provides information on the nature of vulnerability in terms of its physical and socio-economic components intending to inform adaptation decision-making.

Full textAbstract:
As a consequence of climate change, global coastal communities are increasingly at risk from sea level rise and increased storm intensities. Therefore, to inform coastal zone management coastal vulnerability assessments with respect to present and predicted climate change scenarios is important. Most of the literature concentrates on physical, and to a lesser extent socio-economic aspects but no comparable studies detailing coastal vulnerability from both physical and economic vulnerability were found. To fill this important research gap, the current study developed a combined coastal vulnerability (physical + economic) index by integrating both a Physical Coastal Vulnerability Index (PCVI) and an Economic Coastal Vulnerability Index (ECVI). All indices were applied to eleven case study sites across the country and based on assessments, the Combined Coastal Vulnerability Index (CCVI) was validated. Subsequently, coastal areas were ranked according to their PCVI, ECVI and CCVI values. PCVI results showed that Great Yarmouth and Happisburgh have high vulnerability, contrasted against an Aberystwyth frontage that was least vulnerable. ECVI assessments showed that both Great Yarmouth and Skegness have high economic vulnerability while Spurn Head had low economic vulnerability. In total, the economic costs related to case study site vulnerability was assessed at £22.36 billion. Combined coastal vulnerability results showed that Great Yarmouth is highly vulnerable with the highest aggregated score (25) followed by Aberystwyth (21). Llanelli (16) and Lynmouth (16) were least vulnerable with respect to site CCVI. This research makes a contribution to knowledge, not just for the UK but on a global level. Each location has a unique set of conditions and economic needs, and was found to be functions of physical and economic pressures, e.g. number of properties, coastal erosion and population. Finding the most effective and sustainable solution is important and one that includes knowledge of environmental impact and socio-economic consequences. The three indices (PCVI, ECVI and CCVI) are justified as tools for planners and policy makers for developing management strategies to improve coastal resilience under scenarios of sea-level rise and climate change.

A erosão costeira é um processo de grande poder destrutivo e que afeta pelo menos 70% da zona costeira no mundo. Entender as causas e os processos que levam à erosão, bem como as regiões mais ou menos sensíveis a ela, é essencial para o correto manejo costeiro. O presente trabalho visa identificar as áreas vulneráveis à erosão através da aplicação de um Índice de Vulnerabilidade Costeira em praias do norte do Espírito Santo (Pontal do Ipiranga, Conceição da Barra) e sul da Bahia (Mucuri, Nova Viçosa, Caravelas, Prado, Cumuruxatiba, Corumbau, Arraial d\'Ajuda, Porto Seguro). O cálculo do índice se deu pela análise de treze indicadores ambientais: número de frentes frias, regime de tempestade, força de ondas, ângulo de incidência das ondas, estimativa de deriva potencial, morfologia da praia, exposição às ondas, presença de rios e/ou desembocaduras, elevação do terreno, vegetação, taxa de ocupação, obras de engenharia costeira e evidências de erosão. Os resultados mostraram que os indicadores \"morfologia da praia\" e \"exposição às ondas\" parecem ser os principais contribuintes para a erosão costeira nos municípios em que foram observados grandes prejuízos na infraestrutura urbana e perigo iminente à população local. Já nos demais municípios que também apresentaram focos de erosão, a combinação entre os indicadores \"estimativa de deriva potencial\" e \"regimes de tempestade\" parece ser a principal influência ao processo erosivo. Com exceção de Pontal do Ipiranga (que obteve um resultado de baixa vulnerabilidade), todas as praias apresentaram um IVC correspondente à vulnerabilidade moderada à erosão. O estudo se mostra eficiente para a determinação do nível de vulnerabilidade relativo entre as praias estudadas.<br>Coastal erosion is a process with great destructive power and affects more than 70% of worldwide coastlines. In order to achieve an effective coastal management, it is important to find and understand not only the causes and process that leads to erosion, but also areas that are more or less vulnerable to it. This study aims to identify erosion vulnerable areas through application of a Coastal Vulnerability Index in Brazilian beaches in north Espírito Santo (Pontal do Ipiranga, Conceição da Barra) and south Bahia (Mucuri, Nova Viçosa, Caravelas, Prado, Cumuruxatiba, Corumbau, Arraial d\'Ajuda, Porto Seguro). The index was calculated using 13 indicators: number of cold fronts, storm impact scale, wave power, angle of wave approach, longshore drift estimation, beach morphology, wave exposure, presence of inlets or river mouths, terrain elevation, vegetation, occupation rate, coastal engineering structures and erosion evidences. In places where great urban infrastructure destruction and imminent danger to local community were observed, both \"beach morphology\" and \"wave exposure\" seem to be the main contributors to coastal erosion. In other locations where erosion evidences were also observed, the combination between the indicators \"longshore drift estimation\" and \"storm impact scale\" seems to be the main influence to erosive process. IVC results showed that all the beaches are in a moderate vulnerability context, except in Pontal do Ipiranga, where the result was for low vulnerability. The study has proven to be effective in defining the relative vulnerability of the studied beaches.

Rising sea levels and extreme events related to climate change are causing serious threats to coastal areas, affecting both natural and human systems. Moreover, there is growing evidence that socio-economic dynamics (e.g. unplanned urbanization, land use and demographic changes) would increase coastal flood risk in the next decades.
In this setting, coastal zones of the Mediterranean region represent highly vulnerable areas to climate-related impacts, as they are characterized by gentle slope environments, especially prone to be inundated by storm surge flooding events and rising sea level. In particular, when considering the geo-physical and morphological features of the Mediterranean shorelines as a whole, the Italian coastal area appears to be remarkably vulnerable to potential risks arising from future climate change scenarios due to its low lying and retreating shorelines, often lacking protection to erosion or storm surge events. Moreover, Italian coastal areas usually result highly populated and occupied by economically valuable assets, thus exposing people, infrastructures and businesses to potential climate-related damages.
Understanding how natural and human-induced drivers will contribute together to rise the vulnerability and risks in coastal areas is of paramount importance for mainstreaming effective climate adaptation and risk reduction policies into coastal zone management.
Moving forward traditional approaches for coastal vulnerability appraisal, an advanced Coastal Vulnerability Index, integrating a composite set of physical, environmental and socio-economic indicators (hereafter combined-CVI), is proposed in this Thesis in order to rank Italian coastal provinces according to their relative vulnerability to extreme sea level scenarios. In particular, hazard-prone areas potentially inundated by sea level rise and extreme water levels (under the RCP8.5 climate scenario) were combined with indicators of geomorphic vulnerability (e.g. elevation, distance from coastline, shoreline evolution trend) and adaptive capacity (e.g. sensible segments of the population, GDP, land use patterns).
According to the temporal resolution of the available data, the methodology was applied by considering two different timeframe scenarios: a baseline representing current climate and land use condition, and a future scenario for the 2050, integrating both climate projections and data simulating potential evolution of the environmental and socio-economic systems.
Results from the application of the combined-CVI in the Italian coast case study, including GIS-based vulnerability maps and related statistics, showed that most vulnerable provinces are located along the North Adriatic coast, the Gargano area and in the Southern part of Italy, due to the very high vulnerability score assumed by climate-related indicators, in both baseline and future scenario. Moreover, the number of provinces assuming higher vulnerability score is expected to increase in the future due to the worsening of climatic conditions, as well as the rising vulnerability linked with changes in the environmental and socio-economic conditions (e.g. land use variations and increase of the elderly population).
Despite constraints posed by data availability, the resulting outputs of the performed analysis represent a useful screening tool about potential impacts induced by climate change and sea-level rise scenarios in the area of concern. Specifically, by providing a relative ranking of most vulnerable coastal provinces, they can be used by coastal managers and environmental planners to identify regions where inundation risk may be relatively higher, considering both environmental and socio-economic features, as well as to draw some considerations about the potential measures required to increase the resilience of coastal communities to sea-level rise and storm surge flooding scenarios, undertaking a sustainable adaptation pathway.

The global warming leads to an increase in sea level, due to the combined
effects of thermal expansion of the oceans, enhanced melting of mountain
glaciers and polar ice sheet. The main impacts of sea-level rise to coastal
environments are erosion, inundation and saltwater intrusion. To assess the
vulnerability of the coastal environment of Taiwan, this study has adapted the
Coastal Vulnerability Index (CVI) technique developed by Gornitz (1990). For
the entire coastline of Taiwan, a coastal GIS that contains as
many as 8 variables
including lithology, elevation, relief, shoreline stability,
relative sea-level rise,
wave height, tidal range, and frequency of typhoon is developed. The CVI then
was complied based on these variables and coasts with the largest CVI, thus
most vulnerable to sea-level rise, could be identified.
The result of CVI evaluation shows that the most vulnerable coasts are located
in low-lying areas such as estuaries, tidal flats, beaches on
both west and east
coast. Coasts of Pali, Yungan, Putai, Chiang chun, Peimen, Ilan, Fulung,
Hualien, Hoping, Kaohsiung being most vulnerable. If future sea-level rise of
2mm/yr is considered, additional coastal area in Nanliao, Tungchiang,
Chengkang, Kaohsiung chiang will be considered most vulnerable. Based on the
result derived from Q-mode factor analysis of the coastal
variables, the coastline
of Taiwan can be classified into three coastal types with eleven coastal
segments.

concerned. The NOAA built up an "environment sensitivity index (ESI)" map for
oil-spills emergency response in 1976. The environmental indicators include shoreline
classification, biological resources and human-use resources, or called socio-economic
resources. They present alike sense within integrated communities in the same
ecosystem of coastal area. They are induced reaction level under the impacts of adverse
changes for safety, survival and reproduction. Furthermore, the index to biological
resources is weighted by "vulnerability" to respond the pollution or the disaster which
endanger security, survival and reproduction for biota. The evaluation of ecosystem by
specified index usually can provide a healthy sign for environmental monitoring. The
sensitivity is actually rather subjective, however it can represent a relative perception
from pollution in biota. In this text, the concept of "ecological health" is introduced.
Also, a marine biotic index (AMBI) is proposed to evaluate the impact by oil. The
proper rank of quantified index for biotic health is needed to be built, too. Building a
framework of suitable evaluation system for biological resources in Taiwan is expected
in near future. There area two oil-spill cases in southern Taiwan are applied by this
model. The simulated results show the coincidence with original report. It means that
the application of AMBI is capable in Taiwan’s marine environment.

Vulnerability occurs at the intersection of natural geophysical forces and human settlement decisions. When humans decide to place themselves and their homes in harm’s way and disinvest in mitigation measures, vulnerability ensues. Human decisions have and continue to play a large role in furthering vulnerability, especially in coastal communities. With roughly 50 percent of the United States’ population currently located on the coast and with rapid development only projected to continue, coastal communities will be faced with a future of exacerbated flood events that will result in increased surface runoff, flooding, and economic losses. This report focuses on better understanding how the build environment exacerbates coastal vulnerability. This research involves the creation of a spatial vulnerability index to flood risk for Galveston County which uncovers the degree with which the built environment is exposed to flood risk and how this vulnerability can be responded to in a manner that builds coastal resiliency.<br>text

Full textAbstract:
Research Doctorate - Doctor of Philosophy (PhD)<br>Bangladesh is frequently cited as a country that is most vulnerable to climate change. In Bangladesh, most of the adverse effects of climate change occur in the form of extreme weather events, such as cyclone, flood, drought, salinity ingress, river bank erosion and tidal surge, leading to large scale damage to crops, employment, livelihoods and the national well-being. Although it is generally stated that women are relatively more vulnerable than men in the context of climate change, few studies have been done to closely examine this statement, especially in Bangladesh. The present study, therefore, investigates the structure of women’s livelihoods, livelihood vulnerabilities and coping capacity in the context of climate variability and change in a disaster vulnerable coastal area (<i>Shyamnagar upazila of the Satkhira district</i>) of Bangladesh. Utilising the concepts such as the sustainable livelihood framework (SLF) and the disaster crunch model (DCM), allows for a greater understanding of these issues on the ground. Moreover, two livelihood vulnerability indexes, namely the LVI and the IPCC-LVI, are used to measure the degree of livelihood vulnerability of women in the study area. The results show that the distribution of five livelihood capitals (human, natural, financial, social and physical) of women are heavily influenced by several climatic events, such as cyclones that periodically affect the region. Women also face several vulnerabilities in their livelihoods, including vulnerability to their income, household assets, lives and health, food security, education, water sources, sanitation and transportation systems, because of ongoing climate change impacts. They only have limited adaptation strategies that enable them to reduce the climate related risks. However, they do practice some traditional coping strategies to assist with the increasing effects of climate change. While quantifying the degree of vulnerability, both of the indexes indicate a ‘high vulnerability’ level in regards to women’s livelihoods. In particular, women are more vulnerable in terms of physical and financial capitals in their present livelihood system. The results indicate that it is extremely important to instigate strategies to help build the adaptive capacity of women to reduce the burden created by their livelihood vulnerability. Overall, this thesis contributes empirical evidence to current debates in the literature on climate change by enhancing an understanding of the characteristics and determinants of livelihood vulnerability of women in the coastal areas of Bangladesh. The findings have important policy relevance for all involved in disaster and risk management, both within Bangladesh itself and outside. The findings of this thesis also allow identification of a range of measures that could be utilized to help address the impacts of current and future climate variability and change in regards to women’s livelihoods, particularly in the poorer, rural-based coastal communities of Bangladesh and, potentially, beyond. Based on the research findings, the thesis also provides some recommendations for improving the sustainable livelihoods of women in the coastal communities of Bangladesh.

Full textAbstract:
The coastal environment represents a dynamic ecosystem, whose evolution is continually conditioned by the action of numerous climatic and anthropic factors, which affect both the coasts and the hydrographic basins. In recent decades, the growing anthropization of coastal areas and the effects of climate change, in terms of both sea level rise and the increase in frequency and intensity of extreme weather events, have caused severe surface losses in the emerged coast. As a result, awareness of the need for better coastal zone management has increased in recent years and there has been a widespread and growing interest in coastal risk assessment methodologies. However, the national and international panorama, in terms of coastal risk assessment, is characterized not only by the presence of different calculation methodologies depending on the coastal region in question, but above all by a great variety and dispersion of factors on which these methodologiesare based. At present, in fact, there is no methodology that is of general validity, which can incorporate all the factors that influence coastal risk, in which the characteristic parameters of the area are calibrated according to a standardized procedure, such as the one proposed in this thesis.
The new risk assessment methodology, proposed in this study, is index-based and is of general validity, and allows to take into account all the hazard and vulnerability factors that come into play in the coastal erosion process. Also, this methodology can be integrated on a free access GIS platform, in order to provide administrations, individuals and stakeholders with valid support both in the planning phase of coastal works and in the management phase of the coastal areas. The developed methodology was calibrated through its application in 54 sample locations in the Calabria region.

Full textAbstract:
Assessment of coastal vulnerability to physical and anthropic processes is a crucial step in coastal risk management, especially in climate change scenarios characterized by sea level rise and increasing human pressure. The application of geomorphological-based indices is a consolidated approach to estimate the degree of vulnerability to erosion processes of low-relief coasts at a regional/wide scale. Such a method is based on the combination of physical variables such as shoreline changes, dune and beach geometry, vegetation, and coastal infrastructures, which are statistically or arbitrarily ranked to extract a vulnerability classification. Recent advances in the availability of UAV platforms with higher performance in terms of flight duration, sensor availability, and mapping resolution provide a unique opportunity for a comparison between high-resolution DEMs and the results that can be obtained from the application of a Coastal Index. In this study, short- and medium-term comparison (i.e. about ten years) of high-resolution DEMs (derived by LiDAR) was performed in one of the sectors of the Ionian coastal belt, providing new insights about the geomorphological evolution of a highly vulnerable sector along a retreating coast. Such a comparison was tested along a sector of the coastal areas of the Basilicata region, southern Italy, that includes the Agri River mouth. The study area is featured by a strong human impact and environmental factors that have promoted in the last years the occurrence of remarkable shoreline retreat and coastal erosion.

The assessment of coastal vulnerability helps prioritize investments to increase coastal resilience. This work aims to map the vulnerability of a 12 km coastal stretch of the province of Alicante, Spain. It is an area where natural spaces with wetlands and important dune ridges alternate with highly urbanized spots. The method calculates a Coastal Vulnerability Index (CVI) through three main indicators: geomorphology (geology, coastal slope, erosion rate, beach width and dune width), hydrodynamics (significant wave height, mean tide range and flood level indicator) and vegetation variables (state of seagrass meadows, depth and width of these meadows and backshore area covered by vegetation). The coastal strip studied was divided into sections of 200 m, obtaining the CVI on each one. The vulnerability of each variable was evaluated from 1 (Very low) to 5 (Very high) and the overall CVI was obtained. The higher values of CVI were detected in the urbanized areas (41% of the sections). Dune ridges serve as barriers to flooding and reduce erosion. A sufficient beach width and slope are crucial to preventing flooding during extreme weather events.

AbstractFor their livelihood activities, rural farming communities depend more on extractive capital. Their capacity to cultivate sufficiently for their family maintenance is greatly impeded by the absence of either temperature or rainfall quantity pattern or uniformity. The divergent effects of recent extreme weather events around the world, including within relatively small geographical areas, exemplify the unequal impacts of climate change on populations. Akwa Ibom State has been found vulnerable to extreme weather events, such as flooding, severe storms, and rising sea levels, leading to homelessness, poverty, conflicts, and war for millions of people. All of these have resulted in social disturbances and dislocations among rural populations, especially in coastal communities, making them more vulnerable to climate variability. In the field of social vulnerability in the state, not much has been achieved. This chapter analyzes the vulnerability of the rural population to climate variability; the socio-economic characteristics of the rural population; the index of social vulnerability of rural dwellers to climate variability; social vulnerability factors; and the rural population’s social vulnerability mitigation initiatives in Akwa Ibom State, Nigeria. Social science approaches to human vulnerability draw critical attention to the root causes and factors why people are forced to respond to risks from climate change. A complex social approach to vulnerability is most likely to enhance mitigation and adaptation preparation efforts, given that vulnerability is a multidimensional mechanism rather than an invariable state.

This chapter includes an assessment of physical vulnerability of the coast, including a coastal vulnerability index composed of 9 physical variables—elevation, distance to shore, tide amplitude, significant wave weight, erosion/accretion rates, geology, geomorphology, ground cover vegetation, and anthropogenic actions—followed by a quantification of coastal recession and the data of special report on emissions scenarios (SRES) developed by the Intergovernmental Panel on Climate Change (IPCC) on the rise in average sea level. It includes an estimate of the economic value of an area of recreation based on the travel cost method. Finally, a bibliographic review is made to assess strategies and responses to the impacts of sea level rise in order to make comparisons and to develop a road map of interventions for shoreline protection. The proposed methodology was applied to a case study on the Portuguese coast corresponding to the beaches of Costa de Caparica, Almada.

Floods are highly relevant extreme events with increasing frequency at a global scale. They remain among the most dangerous and complex natural disasters in middle and low-income countries. In this context, it is necessary to develop decision-support tools to reduce the flood risk and increase the resilience. The chapter reviews one of the most relevant tools, the flood vulnerability index (FVI) category at a global scale. These tools use hydrological, topographic, socio-economic parameters strongly associated with flood vulnerability. The findings indicate that FVI is a flexible tool for integrated assessment of vulnerability to floods for application in different regions. Social, environmental, and physical components are the main components used in the FVI. Household and neighborhood, basin, urban, sub-catchment, and coastal are the different levels of vulnerability analysis.

The sea level continues to rise at an accelerating pace. Events associated with extreme sea levels, which were rare in the past, will become more frequent in many places by 2050. This paper presents an analysis of coastal vulnerability to sea level rise conducted for the coast of Primorje-Gorski Kotar County. The commonly used Coastal Vulnerability Index (CVI) was adapted for the indented Croatian coast and defined by five representative variables. The results show that only a small part of the county is vulnerable, but that the low-lying, populated areas are particularly vulnerable. Therefore, coastal flooding analyses were also made for the four most threatened settlements. A prerequisite for high-quality analyses is accurate geodetic data. In this case, the topographic data were three-dimensional point clouds. The flooding analyses show that the risk varies from place to place and that the implementation of adaptation measures requires an individual approach for each area at risk.

Full textAbstract:
This study aims to analyse the vulnerability of yacht marinas in Bodrum to sea level rise (SLR) compound impacts using seven spatial physical and eight socio-economic parameters. A new integrated marina vulnerability index (IMVI) was developed as a composition of the physical coastal vulnerability index (PCVI) and non-physical marina vulnerability index (MVI). To determine vulnerability values, coastal vulnerability index approach was used. A geo-database was created using spatial and tabular data collected from different data source. The PCVI parameters were converted to a 1-5 scale by using geographic information systems analysis (GIS) (subset, buffer, slope, reclass, map algebra), and PCVI values were calculated. The MVI parameters were converted to a 1-5 scale by using the natural break classification method, and MVI values were calculated. Both PCVI and MVI results were presented as maps and tabular values using a scale of 1 (Very Low Vulnerability) to 5 (Very High Vulnerability). The results provide comparative vulnerability analyses of seven marinas, using the PCVI and MVI, individually and, their combination with IMVI. The findings showed that the physical vulnerability of marinas was generally higher than their socio-economic vulnerability. While the physically very high vulnerability marinas are Turgutreis, Yalikavak and Ortakent, the marina with very low socio-economic vulnerability is Ortakent. According to IMVI results, Turgutreis, Yalikavak and Milta are the vulnerable marinas both physically and socio-economically. Consequently, this study potentially brings a new perspective to research on SLR-induced climate impacts not only for marinas but also for cargo ports.

Full textAbstract:
The seismic vulnerability assessment of existing urban areas provides fundamental information about the process of reduction of seismic risk in different phases of planning and emergency management. This contribution presents recent advances in seismic vulnerability assessment in Croatian coastal areas at different scales, starting with a detailed analytical approach at the building scale to large-scale assessment at the building level and the level of the homogeneous zones. The investigation was performed in the City of Kaštela, a typical coastal settlement that has expanded over past centuries, resulting in a heterogeneous distribution of the buildings built in periods with different technical regulations. A detailed nonlinear-linear analysis of important buildings (historical, public) has been performed providing evidence of their collapse behaviour. A comprehensive hybrid approach to large-scale seismic risk assessment, combining seismic vulnerability indices with critical PGAs for different limit states, has been applied to define vulnerability curves that allow to relate vulnerability index, damage index and peak ground acceleration. The outcome of this analysis is large-scale risk representation in terms of the damage and seismic risk indexes at the building level. The level of seismic risk to the community depends on several other parameters whose activation reduces the resilience to extraordinary events. Considering the characteristics of the observed pilot site, additional criteria for the risk assessment of homogenous zones are, for instance, communal infrastructure, road network, construction density, inhabitation density, importance factor (public building, school, etc.), and status of protected historical buildings. A methodology for seismic risk assessment of the area at the level of the homogeneous zones is based on Spatial Multi-Criteria Decision Making and the PROMETHEE method. The presented approach for seismic risk assessment has important operational outcomes in the seismic risk management of the investigated area.

Groundwater contamination is becoming a major concern worldwide, especially in the coastal regions, due to the threat of seawater intrusion. Keeping in mind growing freshwater contamination problems, especially in eastern India, the current study was conducted to assess the hydrogeological and geochemical characteristics and critically analyze the aquifer vulnerability to seawater intrusion in a coastal alluvial ‘leaky confined aquifer’ of West Bengal and Odisha. The seasonal (Pre-Monsoon and Post-Monsoon) groundwater-level and quality (EC, Clˉ and HCO3ˉ) data of the ‘leaky confined aquifer’ in 2021 and well logs data were used in this study. Two overlay-and-index-based methods were applied, namely, ‘Original GALDIT’ and ‘Modified GALDIT’ (GALDIT-AHP) methods. The five GALDIT model parameters/themes considered are: ‘Aquifer Hydraulic Conductivity (A)’, ‘Groundwater Elevation (L)’, ‘Distance from the Coastline (D)’, ‘Extent of Seawater Intrusion (I)’, and ‘Aquifer Thickness (T)’. The weights of the themes and their features were modified using the Analytic Hierarchy Process (AHP) method, and the raster layers of themes were integrated in ArcGIS v10.8.2 using the ‘Weighted Overlay’ tool. Results reveal that the ‘Original GALDIT’ method delineated 50–64% lesser, 47–61% higher and 3–4% higher areas under ‘Low’, ‘Moderate’ and ‘High’ vulnerability classes, respectively, compared to the three corresponding EC classes. Results further indicate that the ‘Modified GALDIT’ (GALDIT-AHP) method predicted 32–45% lesser, 14– 24% higher and 17–21% higher areas under ‘Low’, ‘Moderate’ and ‘High’ vulnerability classes, respectively, than the EC classes. The spatial validation method and correlation analysis results suggest that the ‘GALDIT-AHP’ (r=0.712–0.742) method performed much better than the ‘Original GALDIT’ (r=0.518–0.589) method in delineating aquifer vulnerable zones. Therefore, the combined application of geospatial technologies (Remote Sensing/GIS) and multi-criteria decision making techniques (like AHP) provides a reliable approach for seawater intrusion vulnerability assessment. The outcomes of this study will aid in formulating efficient plans for the sustainable management of groundwater resources.

Full textAbstract:
Due to the significant demand for land resources and rapid urbanization, reclamation has become one of the essential choices for developing coastal cities. However, the intensive reclamation projects lead to the high vulnerability of the delta. Attention to the general discussion of ecological security, vulnerability, and sustainability has proliferated in recent years, but insufficient attention has been paid to a detailed explanation of the specific human activities' impact on the overall delta from a narrative historical aspect. In this article, the Deltas of Netherlands and Pearl River Delta (PRD) in multiple scales are selected as cases. The two deltas share similarities in geography, physical system description, ecological system, management Issues, and human activities. The comparative analysis offers a means to improve the understanding of mechanisms for addressing ecological vulnerability by comparing two deltas in social and environmental aspects.The analysis section elaborates the similar reclamation history of two deltas by the sequence of three stages. By comparing the diverse responses of respective projects in macroscale and microscale with similar morphological and ecological features, it is effortless to improve the understanding of reactive mechanisms of systems, which directly affect the vulnerability index. The Vulnerability index will also be listed and elaborated corresponding to the historical stages. Moreover, successful examples of the Netherlands show the advanced experiments in guild thinking, governance, strategies. Thus, the comparative analysis provides comprehensive syntheses, mechanistic insights, and feasible alternatives to PRD. And beneficial guidance to develop a sustainable urban delta could be proposed.

This report describes publicly available data sets and quantitative analysis that local communities can use to evaluate environmental justice concerns associated with pipeline projects. We applied these data and analytical methods to two counties in North Carolina (Northampton and Robeson counties) that would be affected by the proposed Atlantic Coast Pipeline (ACP). We compared demographic and vulnerability characteristics of census blocks, census block groups, and census tracts that lie within 1 mile of the proposed pipeline route with corresponding census geographies that lie outside of the 1-mile zone. Finally, we present results of a county-level analysis of race and ethnicity data for the entire North Carolina segment of the proposed ACP route. Statistical analyses of race and ethnicity data (US Census Bureau) and Social Vulnerability Index scores (University of South Carolina’s Hazards & Vulnerability Research Institute) yielded evidence of significant differences between the areas crossed by the pipeline and reference geographies. No significant differences were found in our analyses of household income and cancer risk data.
