Green infrastructure inequality in the context of COVID-19: Taking parks and trails as examples

Urban green infrastructures play a critical role in enhancing the well-being of residents, yet their equitable access remains a concern, particularly during the COVID-19 outbreak. There is a lack of knowledge on how people respond to the pandemic regarding the usage of green infrastructure in cities. This paper explores the shifts in visitation to parks and trails, two popular types of green infrastructures in Salt Lake County, Utah, by analyzing the results of a survey conducted during the pandemic. Our conceptualization considers personal and neighborhood level factors, including personal socioeconomic status, existing inequalities of green infrastructures, urban form, and neighborhood conditions. People who reside close to the city center tend to go to parks more often, while those living in urban edges use trails more. Visiting green infrastructures less often is more likely in areas with higher COVID-19 infection rates. The regression results confirm the importance of neighborhood level factors and illustrate the intricate elements influencing people's decisions to visit different green infrastructures during the pandemic, which shows non-linear relationships. Wealthier, white, and younger people seem to enjoy green infrastructures more often, leading to the concern of amplified inequality. Higher COVID-19 cases result in higher demands for green infrastructures, which are not fulfilled during the pandemic, especially for vulnerable communities, leading to spatial exclusion. The findings highlight the importance of smart growth, including compact development, public transit, and pocket parks, in promoting the urban resilience of park and trail visits, as they may provide more opportunities for access and alternatives to green infrastructures even in the context of the pandemic.
