Coping with increasing water demand of rapidly-growing cities in Sub-Saharan Africa will require new and innovative planning and management solutions. This book presents Integrated Urban Water Management, an innovative and holistic approach for all components of the urban water cycle to better adapt to current and future urban water challenges.
Africa is currently the least urbanised region in the world, but this is changing fast. Of the billion people living on the African continent, about 40 per cent live in urban areas. The urban population in Africa doubled from 205 million in 1990 to 400 million in 2010, and by 2050, it is expected that this would have tripled to 1.23 billion. Of this urban population, 60 per cent are living in slum conditions. In a time of such urban growth, Africa is likely to experience some of the most severe impacts of climate change, particularly when it comes to water and food security. This places huge pressures on the growing urban populations. This report shows that there is a way forward for a more sustainable future where restoration of ecosystems, often in the green hills and watersheds surrounding cities, can provide cheaper, efficient and resilient water supply systems in a changing world.
The State of the African Cities 2010 goes above and beyond the first report, which provided a general overview of housing and urban management issues in Africa. With the subtitle: Governance, inequity and urban land markets, the report uncovers critical urban issues and challenges in African cities, using social and urban geography as the overall entry points. While examining poverty, slum incidence and governance, the report sheds more light on inequity in African cities, and in this respect follows the main theme of the global State of the World's Cities 2010 report. Through a regional analysis, the report delves deeper into the main urban challenges facing African cities, while provoking dialogue and discussion on the role of African cities in improving national, regional and local economies through sustainable and equitable development. The report has been drafted in cooperation with Urban Land Mark. Through an analytical survey of several African cities, the report examines urban growth, social conditions in slums, environmental and energy issues and, especially, the role of urban land markets in accessing land and housing.
