This paper addresses the issues of urbanisation and green growth in Africa from the perspective of what it would take for African cities and countries to accommodate the upcoming urban explosion without the usual negative impact on the physical environment, and using it as an opportunity for innovative and green growth. The paper is organised in four parts. Part I reviews the performance of the African region, economic growth, urban expansion and the characteristics of the urbanisation process. Part II suggests a framework to discuss green growth at city level. It focuses on sectors normally under city responsibility (land, buildings, waste, urban transport) and reviews the use of public policies, including regulation, pricing, tax and investment criteria. Part III discusses combinations of policies for African cities at different stages of urbanisation and urban growth. Part IV summarises the key points for a forward-looking policy agenda. The reports draws on literature produced on Green Economy by UNEP, the World Bank, OECD, African Development Bank and provides relevant examples from Africa and cities in the world.
