Presented at the Pro-Poor Urban Development: China and Africa Workshop, Nairobi, 07/30/2012. Introductory Session on "Participatory mapping of urban poverty" by Allan Cain, Director, Development Workshop, Angola. This paper explains a method for measuring urbanization and its impacts, as well as how to measure pro- poor urban development and movement from urban poverty to urban wellbeing. One method for measuring the impacts of urbanization and urban poverty, is in relation to the Millennium Development Goals (MDGs). The MDGs challenge countries to reduce poverty by 50% from the years 2000- 2015 and create pro-poor and healthy cities. As 2015 draws closer, the examination of these issues increase in importance. The UN-HABITAT Global Urban Observatory identifies five indicators for poverty reduction, related to MDG Goal 7 (ensuring environmental sustainability), Target 11 (improving the lives of at least 100 million slum dwellers by 2020): access to adequate potable water, access to improved sanitation, sufficient living space in urban areas, durable and safe housing, and secure tenure.
