Urbanization-environment conundrum: an invitation to sustainable development in Saudi Arabian cities

As rapid urbanization becomes a key topic within urban studies and planning particularly in the Global South, it needs to be considered what radical implications to urban environment mean. Reviewing literature on urbanization and its implications on urban environment from within the Global South and on sustainable development research and environmental studies, this article discusses eight implications of urbanization-environmental conundrum: pollution, water resource degradation, urban heat island effect, sea level rise and urban flooding, urban sprawl and slum growth, urban agriculture decline, public health deterioration, and urban wetland destruction that question the ontology of urbanization in Global South cities. Drawing on cases from Saudi Arabian cities, findings indicate that sustainable development agenda is skewed towards socio-economic development with limited focus on environmental issues. This situation is threatening the sustainability of rapidly urbanizing cities. The paper proposes a rhizomatic understanding of environmental importance as a roadmap for sustainable and transformative urbanization in Global South. This ontology changes understandings of what sustainable urbanization should be in rapidly growing Global South cities.
