Purpose: The aim of the study was to assess the impact of urbanization on local climate patterns in South Africa.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: Urban heat island (UHI) phenomenon, where cities experience higher temperatures compared to surrounding rural areas due to the absorption and retention of heat by buildings, roads, and infrastructure. This leads to increased energy consumption for cooling, elevated air pollution levels, and altered precipitation patterns. Additionally, urban areas often experience reduced vegetation cover, which diminishes the cooling effects of shade and evapotranspiration, further exacerbating the UHI effect. Changes in land use and surface properties can also disrupt local wind patterns, affecting air circulation and contributing to microclimatic variations within urban areas. Overall, the impact of urbanization on local climate patterns underscores the need for sustainable urban planning strategies to mitigate adverse effects and enhance urban resilience to climate change.
Implications to Theory, Practice and Policy: Urban heat island theory, land use/land cover change theory and social-ecological systems theory may be used to anchor future studies on assessing the impact of urbanization on local climate patterns in South Africa. Integrate green spaces, such as parks, green roofs, and urban forests, into urban design to mitigate urban heat island effects, improve air quality, and enhance resilience to climate extremes. Develop and implement climate adaptation plans that address the unique climate risks faced by urban areas, including heatwaves, flooding, and extreme weather events.
