In this study, we employed a number of geospatial techniques to examine the spatio-temporal patterns and changes of environmental attitudes and place attachment values in the Gauteng province of South Africa. The data were obtained from the Gauteng City Region Observatory’s Quality of Life Survey collected at three separate points in time, namely 2013, 2015, and 2017. Results indicated that wards (smallest administrative and analysis units) located on the urban periphery of Gauteng, which are generally less affluent, largely held more negative environmental attitudes and place attachment values during the three time periods. In contrast, centrally located wards, which are generally more affluent, expressed more positive environmental attitudes but less place attachment values, especially in 2017. The findings of this research not only highlight the complex spatio-temporal distribution of environmental attitudes and place attachment values throughout Gauteng but also emphasize the need for spatially targeted state interventions for future environmental planning within the province.
