Abstract: Worldwide one billion people live in slum settlements characterized by the absence of access to one or more of five criteria: sufficient access to water, sufficient access to sanitation, durable housing, secure tenure, and sufficient living space for inhabitants. This number is set to double by 2030 and most of this growth will occur in smaller cities without adequate expansion of infrastructure. This chapter presents findings from remote sensing supported analysis of slum settlements around the world, which shows that while research currently focuses mainly on a limited set of very large slum settlements, 85% of slums are on average the size of a football field. To gain deeper insights into and develop relevant planning responses to health risks in these settlements a more integrated design of research is necessary, combining remote sensing with qualitative field-based methods and building up scalable and comparative data.
