Fig. 7. Maps of census tracts in the City of Johannesburg district municipality. Census tracts are colored by relative street greenness (A, D), income (B) and race (C, E). The height of census tracts in D and E represents income. Empty space within the city represents non-residential areas that were not accounted for in the 2011 census.

Urban green infrastructure provides ecosystem services that are essential to human wellbeing. A dearth of national-scale assessments in the Global South has precluded the ability to explore how political regimes, such as the forced racial segregation in South Africa during and after Apartheid, have influenced the extent of and access to green infrastructure over time. We investigate whether there are disparities in green infrastructure distributions across race and income geographies in urban South Africa. Using open-source satellite imagery and geographic information, along with national census statistics, we find that public and private green infrastructure is more abundant, accessible, greener and more treed in high-income relative to low-income areas, and in areas where previously advantaged racial groups (i.e. White citizens) reside.

Fig. 2. The frequency distributions of per capita monthly income are plotted, as stacked histograms for each race category (A). Median income values per race are plotted with dashed lines. The relation between monthly income and population density across racial categories is plotted with linear regression lines and 95% confidence interval ribbons (B). Each point is a census district. The frequency distribution of census tracts across proportional racial population composition are plotted in C. P

Fig. 8. Trajectories in neighborhood greenness (relative to city means) are fitted with linear trend line (solid lines) and generalized additive model lines (dashed) for each race category (A). The distribution of regression line slopes (i.e. slope of linear trend line in A) per census tract are displayed using a violin plot with data medians and interquartile ranges plotted with dots and horizontal bars (B).
