On average, almost two-thirds of urban residents across 15 cities in the global South lack access to safely managed sanitation, with access lowest in cities of South Asia and Sub-Saharan Africa.
New research finds nearly two-thirds of sewage and human waste in 15 major cities is unsafely managed, worsening urban sanitation crisis.
This working paper describes sanitation access challenges in cities of the global south that have been overlooked in global indicators. In analyzing 15 cities, we found that almost two-thirds of urban residents lack access to safely managed sanitation, with access lowest in South Asia and Sub-Saharan Africa. For these households, sanitation services are too expensive or unsafe. This paper highlights four key action areas for cities to improve sanitation access: extend the sewer and simplified sewer networks to household, communal and public toilets; support and regulate on-site sanitation in the absence of sewer systems; support citywide settlement upgrading; and make sanitation services affordable for all.
In the most recent World Resources Report case study, WRI Ross Center for Sustainable Cities looks at progress in sanitation in Kampala, where a decentralized system that puts the needs of the poor first now treats 32 times more human waste.
This case study in the World Resources Report, Towards a More Equal City, examines transformative urban change in Kampala, Uganda, by following its sanitation reforms. The research follows the political process that created favorable conditions for the implementation of innovative solutions to sanitation service provision. The unfolding change remains vulnerable to shifting fiscal priorities and local political instabilities, however, with continued support from all stakeholders, it seems likely that the urban change in Kampala will be sustained.
