In the face of serious disruptions to local livelihoods and asset bases by extreme climatic events, it is paramount to reconstruct but also to transform and diversify livelihoods. However, the literature on these aspects is scant. In this paper, we posit that two frameworks, namely the livelihood strategy approach and community resilience thinking, are useful tools for effectively analyzing post-disaster transformational changes. In the empirical context of coastal communities of Bangladesh, our study specifically examines the changes experienced in livelihood assets due to Cyclones Sidr and Aila. Two coastal communities, namely Nilganj and Dhulasar Unions in the Kalapara Upazila of Patuakhali District, were selected to analyze the strategies used by local people to cope with and adapt to cyclone and storm surge disaster-shocks. Primary data were collected from three sources: a socioeconomic survey of 300 households, eight focus group discussions, and 20 key informant interviews. Our findings reveal that a significant number of cyclone victims were displaced from their homes by recent severe cyclones, changed their occupations -- both intra- and intersectorally -- and confronted increased consumption and social costs. We observed significant differences in impacts between farmers and those engaged in other occupations, such as fishing, with the latter being far more likely to change occupation post-disaster. The study uncovered significant evidence that local people are learning to live with change and uncertainty by nurturing and combining various types of knowledge and social memory, generating diversified livelihood options, and self-organizing to enhance their resilience to future extreme weather events.

面对极端气候事件对当地生计和资产基础的严重破坏，重建生计和转变生计并使之多样化至关重要。然而，关于这些方面的文献很少。在本文中，我们假设生计战略方法和社区韧性思维这两个框架是有效分析灾后转型变化的有用工具。在孟加拉国沿海社区的实证背景下，我们的研究专门研究了由于飓风 Sidr 和 Aila 造成的生计资产的变化。选择了两个沿海社区，即 Patuakhali 区 Kalapara Upazila 的 Nilganj 和 Dhulasar Unions，来分析当地人用来应对和适应气旋和风暴潮灾害冲击的策略。主要数据来自三个来源：对 300 户家庭的社会经济调查、八次焦点小组讨论和 20 次关键知情人访谈。我们的调查结果显示，近期严重的飓风使大量飓风受害者流离失所，改变了他们的职业——包括部门内和部门间——并面临消费和社会成本增加的问题。我们观察到农民与从事其他职业（如渔业）的人之间的影响存在显着差异，后者更有可能在灾后改变职业。该研究发现了重要的证据，表明当地人正在通过培养和结合各种类型的知识和社会记忆，创造多样化的生计选择，学会适应变化和不确定性，
