Rapid Urban Growth in Africa Poses Challenges Nicolas Pinault PARIS - Africa is projected to have the fastest population growth in the world over the next 30 years, and the majority of this growth will take place in urban areas. This transition is profoundly transforming the continent. African urbanization is massive and already a reality on the continent. According to a new report from a Paris-based policy group, the Sahel and West Africa Club, more than 50% of Africans already live in one of the 7,600 urban areas across the continent. In the coming decades, existing cities are expected to grow and many new cities to emerge. Philipp Heinrigs is a senior economist at the Organization for Economic Cooperation Development. "Urbanization will continue in Africa and current projections indicate that Africa's population will double between now and 2050," Heinrigs said."Two-thirds of this population growth will be absorbed by urban areas, which means that in the next 30 years African cities will be home to an additional 950 million people." These demographic trends create many challenges for city officials, who often lack the policies, funds or data to cope with rapid expansion. .
