ABSTRACT

Urbanization can negatively affect residents’ health and wellbeing. Green stormwater infrastructure (GSI) is increasingly advocated as a win-win strategy for addressing multiple urban problems. Literature quantifying GSI benefits is growing, but it is unclear how it performs in arid and semi-arid cities. This study, co-designed with practitioner partners in Phoenix, Arizona, evaluates the current state of knowledge on GSI performance with respect to hydrologic, water quality, urban heat, and air quality benefits. Our systematic literature review confirms a lack of research quantifying GSI performance in arid and semi-arid cities. Our findings, which we summarize in the paper and present in a searchable, online database, suggest that GSI is beneficial in mitigating runoff, urban heat, and air pollution in the surrounding area to some degree. Results for water quality are more mixed. This points to the need for more GSI monitoring and research, especially of air and water quality benefits.

干旱和半干旱城市环境中的绿色基础设施绩效

摘要

城市化会对居民的健康和福祉产生负面影响。绿色雨水基础设施(GSI)越来越多地被认为是解决多个城市问题的双赢策略。量化GSI收益的文献越来越多,但尚不清楚其在干旱和半干旱城市的表现如何。这项研究是与亚利桑那州凤凰城的医疗从业者合作伙伴共同设计的,旨在评估有关GSI在水文,水质,城市热量和空气质量方面的表现的知识水平。我们的系统文献综述证实了缺乏对干旱和半干旱城市中GSI表现进行量化的研究。我们的发现在本文中进行了总结,并显示在可搜索的在线数据库中,这表明GSI在一定程度上有助于缓解径流,城市热和周围地区的空气污染。水质的结果则好坏参半。这表明需要更多的GSI监测和研究,尤其是空气和水质方面的好处。
