Study Reveals Chicago Hispanic Neighborhoods Have Less Green Space

Lawndale News Chicago's Bilingual Newspaper - Local NewsResidents of Chicago’s Hispanic neighborhoods live farther from nature and its benefits than do residents of the city’s non-Hispanic neighborhoods, University of Illinois at Chicago researchers say.

UIC biologists studied four natural attributes — tree coverage; distance to Lake Michigan; distance to large, open green spaces; and bird diversity — of more than 820 census tracts in the city.

Lead author Amélie Davis, a postdoctoral researcher, says many surveys have looked at the distribution of green infrastructure across socioeconomic gradients, but most such studies have looked at just one natural attribute. The new study examined multiple environmental variables.

Using socioeconomic data from the U.S. Census Bureau’s 2005-2009 American Community Survey, the researchers found that three types of neighborhood stood out statistically: those predominantly housing low-income African Americans; those of low- to mid-income Hispanic residents; and those of the higher income group, which were not
classified by race.

“We found that the high-income tracts and the low-income African American tracts essentially had about the same level of these environmental variables, except the latter group was significantly farther away from Lake Michigan,” Davis said.

In contrast, tracts with more low- to mid-income Hispanic residents “tend to be farther away from [both] Lake Michigan and open space, and the amenities they provide,” Davis said. Those tracts also have fewer trees cover and less biodiversity of bird species, she said – findings she called unexpected.

Open spaces, such as parks and forest preserves, offer recreational benefits, facilitate stormwater runoff, and help regulate microclimate. Birds — in addition to their esthetic value — can be an indicator of a neighborhood’s ecological health and offer benefits to humans in the way of seed dispersal and insect consumption.

“There is evidence that people who experience more greenness around them can feel better mentally and perform better on tasks,” said senior co-author Emily Minor, assistant professor of biological sciences at UIC. Do the findings suggest environmental injustice in Chicago? Davis and Minor caution that further study is needed.

They speculate that the disparity could be due to the relatively recent arrival of Hispanic immigrants to Chicago, with their later arrival leading to settlement in locations with fewer trees and farther from the lake. They also note a possible public-knowledge gap about the value and importance of trees, or of municipal forestry services available.

Other co-authors on the study are UIC graduate students Amy Belaire, Monica Farfan, Dan Milz, and Eric Sweeney, and Scott Loss of the Smithsonian Migratory Bird Center. The findings are published in Ecosphere, an online journal of the Ecological Society of America.
