Abstract
Thabo Mofutsanyana District is a rugged and mountainous area located in the eastern part of the Free State Province, South Africa. The area owes its ruggedness to the Drakensberg and Maloti Mountains. Mountain areas have been reported to be more sensitive and vulnerable to climate change, making it necessary to assess climate change in such areas and the surrounding urban areas. This study aimed to identify the negative impacts of climate change in the Thabo Mofutsanyana District and assess how urban planners responded to these impacts. This study used mixed-research methods, including climate data collected from the Koninklijk Nederlands Meteorologisch Instituut (KNMI) Climate Earth Explorer analysed using Microsoft Excel. It used social data from formal interviews with local urban planners and survey questionnaires distributed to urban residents. The social data was analysed using Statistical Package for Social Sciences (SPSS) and Microsoft Excel. Lastly, the study used spatial data from Google Earth Explorer, and PlanetScope analysed using ArcGIS (ArcMap 10.7.1). The results revealed a statistically significant increase in monthly mean temperature (from 1990 to 2020) experienced in Thabo Mofutsanyana District towns, while the decrease in annual total precipitation (from 1990 to 2020) was not statistically significant. This implies that the increase in temperature results from climate change, while the decrease in precipitation is only climate variability. The results further revealed that the urban planners’ strategies implemented to alleviate the impact of climate change were ineffective due to the magnitude of the effects of climate change, especially flooding during heavy rains and extreme temperatures. Furthermore, it was discovered that the exclusion of climate change during urban planning led to a decline in the protection of Green and Blue Urban Ecological Infrastructure (UEI). The increasing Grey UEI is not sustainable as the blocking of drainage systems and the limited porosity of roads do not reduce the effects of climate change, such as flooding. If not effectively maintained, the Green and Blue UEI will continue to decrease in Thabo Mofutsanyana District, affecting the area’s sustainability. The study concluded that sustainable urban planning could mitigate the effects of climate change in cities and small towns, and help communities adapt to these effects effectively. Incorporating climate change during urban planning is necessary.
