This paper aims to scrutinize in what way peri-urbanization triggers climate change vulnerabilities. By using spatial analysis techniques, the study undertakes the following tasks. First, the study demarcates Dhaka’s—the capital of Bangladesh—peri-urban growth pattern that took place over the last 24-year period (1992–2016). Afterwards, it determines the conformity of ongoing peri-urban practices with Dhaka’s stipulated planning documents. Then, it identifies Dhaka’s specific vulnerabilities to climate change impacts—i.e., flood, and groundwater table depletion. Lastly, it maps out the socioeconomic profile of the climate change victim groups from Dhaka. The findings of the study reveal that: (a) Dhaka lacks adequate development planning, monitoring, and control mechanisms that lead to an increased and uncontrolled peri-urbanization; (b) Dhaka’s explicitly undefined peri-urban growth boundary is the primary factor in misguiding the growth pockets—that are the most vulnerable locations to climate change impacts, and; (c) Dhaka’s most vulnerable group to the increasing climate change impacts are the climate migrants, who have been repeatedly exposed to the climate change-triggered natural hazards. These study findings generate insights into peri-urbanization-triggered climate change vulnerabilities that aid urban policymakers, managers, and planners in their development policy, planning, monitoring and control practices.

城市周边化如何触发气候变化脆弱性？孟加拉国达卡特大城市调查

本文旨在详细研究城市外围化以何种方式触发气候变化脆弱性。通过使用空间分析技术，该研究承担了以下任务。首先，该研究将达卡（孟加拉国的首都）在过去的24年中（1992年至2016年）的城郊增长模式进行了划分。之后，它确定了正在进行的城郊实践与达卡规定的规划文件的一致性。然后，它确定了达卡对气候变化影响的特定脆弱性，即洪水和地下水位枯竭。最后，它绘制了达卡气候变化受害者群体的社会经济概况。该研究结果表明：（a）达卡缺乏适当的发展规划，监测和控制机制，导致城市周边城市化的增加和不受控制；（b）达卡明确界定的城市周边增长边界是误导增长区的主要因素，增长区是最容易受到气候变化影响的地区，并且；（c）达卡最容易受到气候变化影响的人群是气候移民，他们反复受到气候变化引发的自然灾害的影响。这些研究结果为城​​市化引发的气候变化漏洞提供了见解，这些漏洞可帮助城市政策制定者，管理人员和规划人员制定其发展政策，规划，监控和控制措施。（c）达卡最容易受到气候变化影响的人群是气候移民，他们反复受到气候变化引发的自然灾害的影响。这些研究结果为城​​市化引发的气候变化漏洞提供了见解，这些漏洞可帮助城市政策制定者，管理人员和规划人员制定其发展政策，规划，监控和控制措施。（c）达卡最容易受到气候变化影响的人群是气候移民，他们反复受到气候变化引发的自然灾害的影响。这些研究结果为城​​市化引发的气候变化漏洞提供了见解，这些漏洞可帮助城市政策制定者，管理人员和规划人员制定其发展政策，规划，监控和控制措施。
