Abstract

Disasters have been a long-standing concern to societies at large. With growing attention being paid to resilient communities, such concern has been brought to the forefront of resilience studies. However, there is a wide variety of definitions with respect to resilience, and a precise definition has yet to emerge. Moreover, much work to date has often focused only on the immediate response to an event, thus investigating the resilience of an area over a prolonged period of time has remained largely unexplored. To overcome these issues, we propose a novel framework utilizing network analysis and concepts from disaster science (e.g., the resilience triangle) to quantify the long-term impacts of wildfires. Taking the Mendocino Complex and Camp wildfires - the largest and most deadly wildfires in California to date, respectively - as case studies, we capture the robustness and vulnerability of communities based on human mobility data from 2018 to 2019. The results show that demographic and socioeconomic characteristics alone only partially capture community resilience, however, by leveraging human mobility data and network analysis techniques, we can enhance our understanding of resilience over space and time, providing a new lens to study disasters and their long-term impacts on society.

社区抵御野火的能力:利用人员流动数据的网络分析方法
长期以来,灾害一直是整个社会关注的问题。随着人们越来越关注具有抗灾能力的社区,这种关切已成为抗灾能力研究的重中之重。然而,关于抗灾能力的定义多种多样,尚未出现一个准确的定义。此外,迄今为止的许多工作往往只关注对事件的即时反应,因此对一个地区长期的恢复能力的调查在很大程度上仍未进行。为了克服这些问题,我们提出了一个新颖的框架,利用网络分析法和灾害科学的概念(如复原力三角)来量化野火的长期影响。以门多西诺山火和坎普山火--分别是迄今为止加州最大和最致命的山火--为案例,我们根据 2018 年至 2019 年的人类流动数据,捕捉了社区的稳健性和脆弱性。研究结果表明,单凭人口和社会经济特征只能部分捕捉社区的恢复力,然而,通过利用人类流动数据和网络分析技术,我们可以加强对空间和时间恢复力的理解,为研究灾害及其对社会的长期影响提供一个新的视角。

期刊介绍: Computers, Environment and Urban Systemsis an interdisciplinary journal publishing cutting-edge and innovative computer-based research on environmental and urban systems, that privileges the geospatial perspective. The journal welcomes original high quality scholarship of a theoretical, applied or technological nature, and provides a stimulating presentation of perspectives, research developments, overviews of important new technologies and uses of major computational, information-based, and visualization innovations. Applied and theoretical contributions demonstrate the scope of computer-based analysis fostering a better understanding of environmental and urban systems, their spatial scope and their dynamics.
