Regional Environmental Change. These papers are based on the findings of this PhD research. As the first author, I designed the research, collected the data, analysed it and wrote the manuscript on my own. The co- authors are my PhD supervisors, who revised and provided feedback on earlier drafts of the papers. ii Acknowledgements I would like to thank the University of Leeds for awarding me the prestigious Leeds International Research Scholarship (LIRS) that sponsored the full-tuition fees and stipend for my 3-years full-time doctoral studies and the School of Earth and Environment for providing the Sustainable Research Institute (SRI) bursary that supported my fieldwork expenses. Moreover, the Research and Training Support Grant (RTSG) enabled me to attend two conferences, where I could share my research findings. This PhD has been made possible by the constant guidance and support of my two supervisors, Dr. Claire Quinn and Dr. Susannah Sallu. Claire has been my primary and only supervisor during the first two years of my study, when I designed my research proposal and conducted my fieldwork. Although Susie joined in the third year, she has given very important inputs in developing my results chapters and writing papers for publications. Their timely feedback and constant encouragement helped me keep up my morale throughout the journey. I’m extremely grateful to the two local key persons, F.M. Parvez and Saifullah Shohag, in the two study sites for providing contextual information about the sites, helping me in recruiting respondents for the field exercises and supporting me in doing the households surveys. My childhood friend, Sadequa, arranged excellent accommodation facilities at her village home (Mithakhali) and helped me network with some knowledgeable people in the village. I would like to thank my college friend, Afzal Hossain, and colleagues, G.M. Parvez and Tushar, for serving as my research assistants and taking notes during group exercises. I’m immensely grateful to the hundreds of respondents who have taken their time to answer the household questionnaires and participate in the livelihood trajectory interviews. My husband, Ishtiaque Shams, has been a tremendous emotional support for me throughout this journey. Although he himself was studying at the University of Manchester, he willingly lived in Leeds with me to make my studies easier. He has been the only one to listen to me during endless moments of frustration. I would also like to mention my elder sister Samia Hoque, who encouraged me to come to UK in the first place. Last but not the least, I’m extremely grateful to my parents for giving me the best possible education and upbringing, that helped me become the person I’m today. My deepest gratitude goes to my mother, Dr. Shamim Ferdous, for going against the cultural norm at that time and educating me in an English medium school, for which I never had to face any language barriers in my tertiary education. iii Abstract Socio-ecological changes, brought about by the rapid growth of the aquaculture industry and the increased occurrence of climatic shocks and stresses, have significantly affected the livelihood dynamics of coastal communities in Asia. Empirical studies, to date, have largely provided a snapshot of the impacts and responses to a particular disturbance at a single spatial scale at a given time, often assessing the characteristics that make certain populations more vulnerable than others. To ensure equitable and environmentally sustainable livelihoods in the future, it is essential to unpack the complex social and ecological dynamics that drive long-term changes in a system’s configurations and shape the adaptive capacities of actors within the system. This study, therefore, explores the drivers, differential livelihood adaptations and well-being outcomes of socio-ecological change in coastal Bangladesh, using poverty as central lens for differentiation. The study takes a socio- ecological systems approach, whereby insights from vulnerability, resilience, political ecology, livelihoods, adaptation, poverty and human well-being are integrated into an interdisciplinary conceptual framework. A mixed methods approach was used to collect empirical evidence from two communities, both of which underwent transformations in farming systems when maintenance of the status quo through incremental adaptation was no longer feasible. Findings show that in the absence of good governance, social power resulting from high wealth status and associated political ties can steer the direction of socio-ecological change to one that is desirable for a small group of powerful stakeholders and completely undesirable for others. Differences in wealth status lead to differences in adaptive capacity; however, changes in vulnerability contexts brought about by power dynamics further exacerbate these inequalities. While resource constraints can restrict a household’s livelihood adaptation options, its adaptation space can also become narrower through negative externalities arising from the activities of other households. This can push some households towards downward trajectories, locking them in a poverty trap. In contrast, good governance and wider participation in decision making, can shift the farming system to one that is desirable for the majority of stakeholders. The study emphasises that resilience building through transformational adaptation should account for the heterogeneous values, interests and needs of different households. This can translate into more equitable adaptive capacities and prevent the system from embarking on a maladaptive trajectory in the future. iv Table of Contents Acknowledgements iii Abstract iv List of Tables x List of Figures xi Abbreviations xiii Chapter 1.
