The last two decades have been marked by a profound turn-around in the perceptions of Africa, both within the continent and internationally. This change has been driven primarily by the exceptional economic growth in many parts of Africa, despite a slow-down and financial crisis about ten years ago. Renewed confidence among many African states is reflected in the Africa 2063 Agenda spearheaded by the African Union. This manifesto puts an important focus on the impressive urbanization of Africa, one of the region's major trends. In 2030 more than one billion Africans will be city-dwellers, while at least six cities will be inhabited by more than ten million citizens. What are the main challenges for African cities in terms of infrastructure, energy, housing, technology, and mobility? What role do governments play? Is it possible to manage this urbanization wave in a sustainable manner, reducing the number of people living in informal settlements and slums?
