Low-Income City Residents Tend to Have Less Access to Greenery
City residents with higher incomes and education tend to have greater access to trees and greenery compared to their less-privileged neighbors, according to a new study published in the journal Landscape and Urban Planning.
Researchers at the University of British Columbia (UBC) looked at census data and highly detailed aerial imagery of 10 major U.S. cities: Chicago, Houston, Indianapolis, Jacksonville, Los Angeles, New York, Phoenix, Portland, Seattle and St. Louis.
They compared the amount of vegetation and parkland available to residents in their home neighborhoods to socioeconomic factors such as income, education, or racial background.
“Vegetation keeps our cities cool, improves air quality, reduces storm water runoff and reduces stress — it makes a huge difference in citizens’ well-being,” said lead author Lorien Nesbitt, a postdoctoral research and teaching fellow in the department of forest resources management at UBC’s faculty of forestry.
“The issue is that when access to greenery isn’t equitable, those benefits aren’t always fairly distributed, reducing access for our most marginalized citizens who need them most.”
Ideally, people should be able to access parks within a 10-minute walk from home and also enjoy trees and vegetation along their street or in their backyard, Nesbitt said.
“For most cities, the more income and education you had, the more access you had to mixed or woody vegetation, while parks were more equitably accessible,” said Nesbitt.
In Indianapolis, for example, both education and income made a significant difference in regards to greenery access. Residents without a high school diploma had lower access to vegetation in their home neighborhoods, while those with post-secondary education and higher incomes had greater access. Similarly, in Los Angeles, residents with post-secondary education and higher incomes had more access to greenery.
In New York, the effect of post-secondary education on access to urban green spaces was very strong, while income played a smaller role. Residents with higher education were much more likely to have access to vegetation in their own neighborhood.
“In larger cities like Chicago and New York, racial and ethnic factors played an important role as well,” added Nesbitt.
“People from Hispanic backgrounds had less access to vegetation in Chicago and Seattle, while people identifying as African-American had less access to green spaces in Chicago and St. Louis. Those identifying as Asian-American had less access in New York.”
The study reveals the need for wider distribution of trees, shrubs and pocket parks as cities continue to grow.
“For many people, the trees in their neighbourhood are their first contact with nature — maybe even the only contact, for those who have less opportunity to travel to natural spaces outside of the city,” said Nesbitt.
“As the effects of climate change intensify, we should plan for more urban green spaces and ensure that citizens from all backgrounds can access them readily and equitably.”
