印度奥里萨邦的大部分地区都容易遭受飓风和洪水的袭击。然而，现有研究主要评估沿海地区的脆弱性，并且主要集中在生物物理部分。因此，全面的脆弱性评估将有助于揭示奥里萨邦各地区的脆弱性规模，并更好地了解家庭对这些极端事件的适应能力。采用“综合方法”来评估脆弱性，该方法被视为暴露程度、敏感性和适应能力的函数。考虑使用许多代理指标来代表这些组成部分，并采用标准化程序将它们汇总为单个值。出现了三个关键观察结果。首先，人们发现敏感性和适应能力等成分是脆弱性的主要决定因素。其次，发现有八个地区的脆弱性得分较高，令人惊讶的是，其中一些地区是非沿海地区。第三，人口、农业和经济能力等因素成为脆弱性加剧的主要原因。这些结果对于通过州和地区层面的灾害风险管理计划优先考虑脆弱地区和决定因素中的有限资源具有政策意义。
Most of the districts in Odisha, India are prone to both cyclones and floods. However, the existing studies have assessed vulnerability mainly for the coastal districts, and are largely focused on the biophysical components. Therefore, a comprehensive vulnerability assessment will help unravel the scale of vulnerability across the districts of Odisha, and provide a better understanding of the adaptive capacity of households towards these extreme events. An 'integrated approach' was adopted to assess vulnerability which is viewed as a function of exposure, sensitivity and adaptive capacity. A number of proxy indicators were considered to represent these components, and a normalization procedure was adopted in order to aggregate them into a single value. Three key observations emerged. First, components like sensitivity and adaptive capacity were found to act as the major determinants of vulnerability. Secondly, eight districts were found to have a higher vulnerability score, and surprisingly, some of the districts are non-coastal. Thirdly, factors like demography, agriculture and economic capacity emerged as the major cause for increasing vulnerability. These results have policy implications in the context of prioritizing limited resources among the vulnerable districts and determinants through the disaster risk management programme at state and district levels.
