Abstract

Marginalized communities are more often at risk of health detriments due to environmental burdens, heat mortality, and other location-specific hazards. This is the basis behind environmental justice: recognizing and bettering the health of these communities by addressing the environmental concerns. Maps are often used as visual proxies in environmental justice research to provide a spatial analysis of environmental hazards. Urban mapping schemes specifically depict the relationship between location and environmental hazards in and around cities. Such schemes are an important part of the climate change adaptation field, especially in urban contexts. The Local Climate Zone (LCZ) scheme has recently provided a way for researchers to further classify urban and rural areas for the use of urban climate studies. This study uses the opensource geospatial toolbox Geoclimate to generate LCZ maps for the area of Atlanta, Georgia, combining this with census-block sociodemographic data from the EPA’s EJscreen tool. The open-source tool QGIS is used to combine and further analyze GeoClimate outputs and EJscreen data, and statistical analyses are performed with R-studio. With these tools and datasets, the study aims to underline the correlation between local climate zone types and three sociodemographic factors: race, income level, and education. Understanding the correlations among these factors can help to provide insights and new potential methods for analysis for urban planning, policymaking, and environmental justice campaigns in the area of Atlanta and other cities like it.
