Urban green infrastructure and pandemic response: how urban parks were used to support the COVID-19 response and the relationship between parkland acreage and excess mortality in large cities in the USA

Abstract

ABSTRACT The coronavirus disease 2019 (COVID-19) pandemic was an unprecedented public health emergency, and relatively little research has investigated the relationship between urban green infrastructure, such as parks, and pandemic-related health outcomes. This study describes how urban parks were used to support the pandemic response and examines the associations between urban park acreage and excess mortality in 2020 in the 50 most populous cities in the USA. The descriptive portion of the study revealed that all cities temporarily closed at least some parks during the first year of the pandemic, and most reported collaborations between parks and public health authorities. Further, urban parks were used to support the pandemic response by serving as venues for meal distributions, diagnostic testing, education and childcare, housing shelters, vaccination clinics, personal protective equipment distributions and other services. A series of linear regression models were used to investigate the association between park acreage and excess mortality. Univariable regression revealed a negative, statistically significant relationship between total urban park acreage and excess mortality rates. However, the relationship weakened and was no longer significant when additional demographic and socioeconomic variables were added in multiple linear regressions. In combination, these results may inform efforts to optimize the design of urban parks and strengthen urban resilience against future infectious disease outbreaks, especially if they consider and address aspects such as park accessibility and equity.
