目标。为了评估飓风哈维在德克萨斯州大休斯顿地区造成的洪水对环境正义的影响，我们在控制了相关解释因素后，分析了洪水的面积分布是否与种族、民族和社会经济地位有关。我们的研究综合了美国联邦紧急事务管理局开发的哈维淹没足迹的地图信息，以及2012-2016年美国社区调查的社会人口统计数据。统计分析基于二元相关和多元广义估计方程。在我们控制了环境因素和聚集之后，哈维引发的洪水的面积范围在非西班牙裔黑人和社会经济贫困居民比例较高的社区中明显更大。结果提供了洪水分布中种族/民族和社会经济不公正的证据，并为更详细地调查与哈维飓风相关的不成比例影响提供了重要的起点。公共卫生影响。我们的研究结果强调，有必要为气候变化相关灾害带来的不平等社会后果做好准备，并解决这些后果，这些灾害预计将在频率和严重程度上增加。
Objectives. To assess the environmental justice implications of flooding from Hurricane Harvey in Greater Houston, Texas, we analyzed whether the areal extent of flooding was distributed inequitably with respect to race, ethnicity, and socioeconomic status, after controlling for relevant explanatory factors.Methods. Our study integrated cartographic information from Harvey's Inundation Footprint, developed by the US Federal Emergency Management Agency, with sociodemographic data from the 2012-2016 American Community Survey. Statistical analyses were based on bivariate correlations and multivariate generalized estimating equations.Results. The areal extent of Harvey-induced flooding was significantly greater in neighborhoods with a higher proportion of non-Hispanic Black and socioeconomically deprived residents after we controlled for contextual factors and clustering.Conclusions. Results provide evidence of racial/ethnic and socioeconomic injustices in the distribution of flooding and represent an important starting point for more detailed investigation of disproportionate impacts associated with Hurricane Harvey.Public Health Implications. Our findings highlight the need to prepare for and address the unequal social consequences of climate change-related disasters, which are expected to increase in frequency and severity.
