The Future of Water in African Cities: Why Waste Water?

Addis Ababa - Ethiopia

Rapid urbanization and its spatial dimensions are key drivers of several aspects of the urban water management challenge. However, traditionally, we know little about the location and size of the future development areas. To fill the void, we created maps of past and future urban extent for 31 African cities based on satellite imagery and on a methodology for projection of future urban extent. For a full description of the methodology used in producing the urban extent maps, see Annex 4 of Jacobsen et al, 2012
