Decoding the Evolution of African Urban Systems: New Insights from a Global Study

An **international research team**, including members from the University of Hong Kong and Wuhan University, has published a comprehensive study on the **evolution of urban systems in Africa**, featured in Nature Cities. The study adopts a **complex systems approach** to uncover the universality, specificity, and explanatory power of rules governing urban development. Employing mathematical models such as **Zipf's law, Gibrat's law, and scaling laws**, the research scrutinizes over 9,200 African towns and cities, revealing a shift toward **larger, concentrated urban populations** and extensive land development unique to the continent. Unlike Western countries, African cities, particularly in East and West Africa, show more extensive land use. The findings offer a new **analytical framework for understanding urban evolution** and guide future global urban science research.
