背景社会不稳定和危机可能导致快速、大规模的人口流动。人们对这些运动了解甚少,难以衡量,但对健康有着强烈的影响。关于这些移动的数据对于规划应对工作很重要。我们使用两种不同的方法回顾性分析了2010年科特迪瓦内部政治冲突造成的人道主义危机的运动模式。方法我们使用两种远程测量方法,夜间灯光卫星图像和匿名移动的电话详细记录,以评估平均人口规模以及动态人口变化。这些数据源检测不同空间和时间尺度上的移动。结果两个数据源在人口规模的平均测量方面表现出很强的一致性。由于数据来源的时空分辨率不同,我们能够在整个危机期间的不同时间点获得对人口长期和短期动态要素的测量。结论使用互补的远程数据源来衡量运动显示出未来在人道主义危机中使用的希望。我们的结论与远程测量运动的挑战,并为未来的研究和方法的发展提供建议。
Background Societal instability and crises can cause rapid, large-scale movements. These movements are poorly understood and difficult to measure but strongly impact health. Data on these movements are important for planning response efforts. We retrospectively analyzed movement patterns surrounding a 2010 humanitarian crisis caused by internal political conflict in Côte d'Ivoire using two different methods. Methods We used two remote measures, nighttime lights satellite imagery and anonymized mobile phone call detail records, to assess average population sizes as well as dynamic population changes. These data sources detect movements across different spatial and temporal scales. Results The two data sources showed strong agreement in average measures of population sizes. Because the spatiotemporal resolution of the data sources differed, we were able to obtain measurements on long- and short-term dynamic elements of populations at different points throughout the crisis. Conclusions Using complementary, remote data sources to measure movement shows promise for future use in humanitarian crises. We conclude with challenges of remotely measuring movement and provide suggestions for future research and methodological developments.
