Although urban greening is universally recognized as an essential part of sustainable and climate-responsive cities, a growing literature on green gentrification argues that new green infrastructure, and greenspace in particular, can contribute to gentrification, thus creating social and racial inequalities in access to the benefits of greenspace and further environmental and climate injustice. In response to limited quantitative evidence documenting the temporal relationship between new greenspaces and gentrification across entire cities, let alone across various international contexts, we employ a spatially weighted Bayesian model to test the green gentrification hypothesis across 28 cities in 9 countries in North America and Europe. Here we show a strong positive and relevant relationship for at least one decade between greening in the 1990s-2000s and gentrification that occurred between 2000-2016 in 17 of the 28 cities. Our results also determine whether greening plays a "lead", "integrated", or "subsidiary" role in explaining gentrification.
尽管城市绿化被普遍认为是可持续和应对气候变化的城市的重要组成部分,但越来越多的关于绿化高档化的文献认为,新的绿色基础设施,特别是绿色空间,可以促进高档化,从而导致人们在获得绿色空间的利益方面存在社会和种族不平等,以及进一步的环境和气候不公平。由于缺乏定量证据来记录整个城市,更不用说在各种国际背景下,新的绿色空间与高档化之间的时间关系,我们使用空间加权贝叶斯模型来检验北美和欧洲 9 个国家的 28 个城市的绿化高档化假说。在这里,我们展示了至少在过去十年中,1990 年代至 2000 年代的绿化与 2000 年至 2016 年期间发生的 28 个城市中的 17 个城市的高档化之间存在强烈的正相关关系。我们的结果还确定了绿化在解释高档化方面是否发挥了“主导”、“综合”或“辅助”作用。
