Quantifying Vulnerability to Climate Change in Bangladesh
Bangladesh is considered to be one of the countries highly vulnerable to climate change. As part of the ADB funded project, "Vulnerability to Climate Change, Adaptation Strategies and Layers of Resilience", analysis of climate change vulnerability using two popular methods was carried out for Bangladesh. A set of indicators defining the three components of vulnerability, ie, exposure, sensitivity and adaptive capacity were selected considering their functional relationship and their contribution to the vulnerability. The aim of the exercise is to characterize different regions and ecological zones (EZ) of the country in terms of vulnerability related to climate change. From the analysis, we conclude that the majority of the regions are very highly vulnerable to climate change. These regions should receive high priority for channelizing resources such as technologies, finances and developmental programs to enhance their ability to cope with the impacts. Appropriate action should be planned and carried out in advance so as to foresee the anticipated impacts of climate change and the expected vulnerability of the regions and the population.

Climate Change Vulnerability Assessment of Patuakhali Municipality in Bangladesh
The Dhaka University Journal of Earth and Environmental Sciences
Climate change will create adversative impact on the growth and development of future cities due to the proliferation of the extreme events, which will increase human, social, and economic losses over time. Therefore, it is necessary to move towards sustainable urbanization processes to reduce the impact of climate change. This research is aimed at carrying out climate change vulnerability assessment (CCVA) for Patuakhali Municipality, which is one of the most vulnerable municipalities in Bangladesh located in the southcentral coastal region of Bangladesh. The vulnerability of the study area is derived by overlaying the factor maps using equal class interval weighted index (ECIWI) and principal component analysis (PCA). Both methods show similar results in case of exposure and adaptive capacity assessment, but the results of vulnerability assessment are slightly different for some of the wards due to variation in the level of sensitivity obtained from two different methods.

Coastal areas are more vulnerable to climate change and natural disasters. Due to increased weather extremes caused by climate change, the coastal communities fall at high risk of casualties and damages. According to DPSIR (Driver-Pressure-State-Impact-Response) framework, population, fisheries, aquaculture, agriculture and tourism are the main drivers of climate change at coastal Shyamnagar upazila which caused several social, financial, environmental and physical impacts. As most of the people are poor and living below the poverty line, the situation becomes worse during and after any climatic hazards. Natural capital, local economy, water and natural disaster etc. are more vulnerable components at the study area in terms of Livelihood Vulnerability Index (LVI) as people are dependent on natural resources from Sundarban for livelihood. IPCC framework of LVI was also determined for this study. The order of LVI for studied unions are: Gabura (0.027)>Padma Pukur (0.0264)>Munshiganj, Kaikhali, Kashimari (0.0242)>Buri Goalini (0.020)>Atulia (0.0172)>Bhurulia (0.0108)>Ishwaripur (0.0105)>Ramjannagar (0.0102)>Nurnagar and Shyamnagar (0.003). According to the index values, the situation is worse at Gabura and Padma Pukur unions. However, most of the unions are highly vulnerable to climate change impacts in terms of exposure and sensitive components which have also exceeded the adaptive capacity.

Climate change refers to any apparent change in the patterns expected of the climate, which occurs in the long term in a particular region or for the entire global climate. These changes are due to unusual occurrences in the Earth's climate. Iran, like many countries, is exposed to climate phenomena, which in turn will exacerbate the crisis of water and drought. In this study, we will analyze this issue against the phenomenon of climate change in order to estimate the vulnerability of Iran, and to this end, we will use the CVI vulnerability index on the provincial scale. By utilizing the results of this research, it will be clear those suitable solutions to increase adaptation to climate change conditions. The results of this research indicate that Hamadan and Alborz provinces have the highest vulnerability and therefore have the least adaptability to climate change compared to other provinces. On the other hand, Khuzestan and Tehran provinces have the lowest degree of relative vulnerability due to rich water resources, literacy rate and industry's GDP. Given the many differences in vulnerability, decision-makers can develop provincial-level policies to control more vulnerability.

Climate change vulnerability assessment (CCVA) can inform adaptation policy and help in incorporating climate futures in planning. The literature on CCVA stems from a number of research paradigms (e.g., risk assessment, natural disaster management, and urban planning), therefore making it difficult to extract major directions and methodologies from this body of work. A large number of assessments are based, partly or totally, on indicators which bring up specific methodological problems and constraints. In this study, first, we discuss the most important methodological challenges facing indicator-based vulnerability assessment (IBVA) based on a set of key conceptual papers in the field. Second, we conduct a meta-analysis of a representative sample of peer-reviewed IBVA studies, to identify how current research on IBVA is engaging with these challenges. We attempt to elicit major thematic and methodological trends in this corpus with specific focus on issues related to geographical and temporal scales, aggregation, and nonlinearity. We find that health of ecosystems and biodiversity (28%), freshwater quantity and quality (12%), and public health (10%) have attracted the highest number of studies. Less than a third of the papers in our sample give some consideration to uncertainty and nonlinearity. Assessments typically use aggregation methods that are based on the Multiple Attribute Utility Theory despite the fact that IBVA rarely satisfies the theoretical requirements of this approach. A small percentage of IBVA studies critically scrutinize prevalent assessment methodologies or attempt to develop new ones, despite the raised questions in key theoretical papers about its methodological aspects.
