The purpose of this chapter is to examine observed and projected land use/cover changes for Johannesburg based on remote sensing and GIS analysis. In addition, the driving forces that influence urbanization as well as the potential implications of urban land use/cover changes on future sustainable urban development in Johannesburg are discussed. The land use/cover change results indicated that built-up areas increased substantially between 1990 and 2014. The rapid increase in built-up areas was attributed to a number of driving factors such as the historical and recent developments in the mining industry, government urban policies, rural-urban migration, and urban land market changes. The observed and projected land use/cover changes provide valuable insights, which can be used to guide sustainable urban development in Johannesburg. This is important given the current distortions in land access and supply as well as poor provision of urban services in Johannesburg. |
