摘要

Addressing the “slum challenge” is essential for urban sustainability and the capacity of cities to provide a minimum quality of life to their residents. To present policy-makers with data to inform strategies to improve the lives of marginalized urban residents, this paper reviews quantitative indicators on slum infrastructure, and demonstrates analyses they can facilitate. First, we review 122 studies on slum infrastructure and report frequently assessed quantitative indicators; access to municipal services is among the most prevalent appearing in 25%–50% of the studies. We then assess how these indicators can increase our understanding of slum settlements, analysing access to services in slums vs the remaining urban population for a subset of cities (Sao Paulo, Rio, Lima, Johannesburg, Mumbai, and Hyderabad). Significant gaps exist between the communities, especially when per capita indicators are compared. Finally, we analyse how these indicators can be used to scope the challenges of achieving universal access to basic services (e.g. water, electricity, and water collection) by 2030. The results show that large infrastructure investments or conservation efforts are needed, especially for solid waste collection and water provision in Mumbai and Hyderabad. Additional work is needed to address data gaps to enable informed policy-making.
