Environmental Justice in Baltimore
Changing Pattern over Time
How have the spatial patterns of environmental equity — defined by access to environmental amenities and disamenities — changed over time? Do patterns of environmental amenities and disamenities spatially correlate more with race/ethnicity or socioeconomic status?
Linking Pattern and Process
What social and institutional processes drive patterns of amenities and disamenities?
Social Dynamics of Environmental Inequity
Do patterns of population characteristics shift at certain threshold densities of amenities and disamenities?
Do population characteristics respond to rapid rates of change in amenity and disamenity densities?
Environmental justice studies typically examine the spatial correlation between environmental disamenities, most often Toxics Release Inventory (TRI) sites, and demographic characteristics of surrounding neighborhoods. An earlier study shows that TRI sites in Baltimore are concentrated in census tracts that are primarily white. Statistical analyses point to majority white census tracts as the best explanatory variable for the presence or absence of a TRI site, a finding in contrast to many other environmental studies that show a concentration of TRI sites in minority neighborhoods. Analysis for the study employed buffering methods to try to reduce the limitations of using large polygons as units of analysis (demographics were weighted in proportion to area of the census tract covered by the buffer), but the results were based on the notion that populations are spread evenly throughout census tracts. A follow-up study using dasymetric mapping methods, however, confirmed these earlier findings. In the City of Baltimore, whites tend to be over-represented in zones near TRI facilities. The single snapshot in time, however, does not explain the processes that generated these unexpected results. BES researchers have conducted a series of longitudinal studies to examine institutional and legacy factors that shed light on the present patterns of inequity. The distribution of TRI sites reflects long-standing segregation practices that kept black residents from living near industries in white neighborhoods. Living close to work, even in a polluting factory, has historically been an amenity enjoyed by the privileged. While the demographics have changed significantly in Baltimore, many of the older, white working-class neighborhoods remain majority white today, and are thus exposed to the toxins released from nearby facilities.
Similar to other metropolitan regions, parks are not distributed evenly in Baltimore. The uneven patterns can be understood as an environmental justice issue, because it denies some areas of the city with the same access to an urban amenity as other neighborhoods. Our results showed unexpected results. We found that a higher proportion of African Americans have access to parks within walking distance, defined as 400 meters or less, than whites, but whites have access to more acreage of parks within walking distance than blacks. A needs-based assessment shows that areas with the highest need have the best access to parks but also have access to less acreage of parks compared to low-need areas. Park service areas that are predominantly black have higher park congestion than areas that are predominantly white, although differences are less apparent at the city level than at the metropolitan level. We examined how segregation ordinances, racial covenants, improvement associations, the Home Owners Loan Corporation, and the Parks and Recreation Board created separate black spaces historically underserved with parks. These mechanisms ultimately fueled middle class flight and suburbanization and black inheritance of much of Baltimore’s space, including its parks.
An analysis of the correlation between race, poverty, and redlining and the location of environmental disamenities in Baltimore shows a statistically significant correlation between race and variances for the period 1940 to 1970, with the correlation weakening after 1970 and disappearing by 2000. Charles Lord has an article forthcoming on these findings in Environmental Law.
Research on long-term trends of household location and floodplains, streams, and shorelines indicates that low-income whites disproportionately live in floodplain areas. The proportion of these households diminishes in the 1960s as formal segregation ends and black populations have more freedom to choose where they live. Household location associated with current and historic streams is not different from general location proportions for the City. In the case of current shorelines, high-income white households are disproportionately associated with these areas, particularly in recent decades. These trends reflect larger processes associated with historic preferences to live close to work (manufacturing jobs located in floodplains), long term segregationist housing practices, and regional demographic changes with older, and lifestyle trends associated with more affluent white households moving back into the city to live close to the water and city amenities.
