Coastal regions are most susceptible to the effects of climate change. To increase infrastructure-resilience of such regions, reduce livelihood-vulnerability of people living in such regions and equip them with appropriate livelihood strategies, governments have invested heavily in coastal infrastructure such as polders. This research is focused on the polders of Bangladesh. The effectiveness of Bangladesh’s polders is disputed. No large-scale, evaluative, quantitative analysis of polders has yet been conducted. There is also only a limited number of evaluative studies on the factors which affect livelihood strategies, livelihood-vulnerability or infrastructure-resilience in polders. Therefore, the research question guiding this research is: What factors affect livelihood strategies, infrastructure-resilience, and livelihood-vulnerability in the polders of Bangladesh? These questions are answered by drawing on propositions from the Sustainable Livelihood Approach (SLA) using statistical analysis of a dataset of 137 polders. This dataset has been created from 76 survey-based interviews, secondary research and geo-spatial analysis. It is hypothesized that under different contextual settings, different combinations of livelihood resource endowments, lead to different combinations of livelihood strategies. These combinations of livelihood strategies lead to different outcomes after being moderated by different institutional, and political settings, under different contextual settings. This research demonstrates that various kinds of conflict-related and rule-making variables affect sustainability outcomes. Relationships proposed by the SLA are statistically significant and are generalizable across a large number of heterogeneous sites. Geological, geomorphological, climatic and hydrological conditions also affect livelihood decisions of polder-residents and also affect the condition of polder-infrastructure.

资本，规则还是冲突？影响孟加拉国地生计战略，基础设施复原力和生计脆弱性的因素

沿海地区最容易受到气候变化的影响。为了提高这些地区的基础设施抗灾能力，减少这些地区人民的生计脆弱性并为其配备适当的生计策略，政府已在governments田等沿海基础设施上进行了大量投资。这项研究的重点是孟加拉国的pol田。孟加拉国田的效力存在争议。尚未对进行大规模，评估，定量分析。关于影响田生计策略，生计脆弱性或基础设施复原力的因素的评估研究也很少。因此，指导这项研究的研究问题是：哪些因素会影响民生策略，基础设施的弹性，和孟加拉国地的生计脆弱性？通过对137个地数据集进行统计分析，利用可持续生计方法（SLA）的命题来回答这些问题。该数据集是根据76个基于调查的访谈，二次研究和地理空间分析创建的。假设在不同的背景环境下，不同的生计资源end赋组合会导致不同的生计策略组合。这些生计策略的组合在不同的背景环境下，由不同的制度和政治环境主持后，会导致不同的结果。这项研究表明，各种与冲突相关的规则和制定规则的变量会影响可持续性的结果。SLA提出的关系具有统计意义，并且可以在大量异类站点之间推广。地质，地貌，气候和水文状况也影响居民的生计决策，也影响基础设施的状况。
