This study employs the interplay of socio economic variables and the concept of environmental justice to assess the fairness of the distribution of green spaces in Ibadan metropolis in terms of sharing of their benefits and burdens. The 104 communities shown on map of the metropolis constitute the units of data collection and analysis. Data sources used include high resolution satellite imagery of Ibadan metropolis for 2015. ARCGIS software was used to extract and measure at community level the green areas. A structured questionnaire addressing the socio economic characteristics of respondents was administered. Using a projected population for 2015 at 1,783, 367, the sampling size is estimated at 3,410 at the four sample percentages of (0.1% 0.2%, 0.4% and 0.8%) respectively. Global Moran'I analysis was used to assess the distributional pattern of green areas in Ibadan metropolis. Multiple correlation and geographically weighted regression analyses are used to determine the significant socio- economic variables that explain the spatial patterns of green spaces at a P ≤ 0.05. The degree of influence of each significant variable is mapped across the metropolis. Results show a clustered distributional pattern of green spaces for 2015 (P = 0.000000). The clustered pattern of green spaces clearly demonstrates lack of environmental justice. There are significant relationships between green spaces and some of the socio- economic variables, notably, occupation (P = 0.001) and income (P = 0.002), which means they largely explain the spatial inequalities in the distribution of green spaces and their benefits and burdens.
