Jonathan Silver, alongside research collaborators Mary Lawhon, David Nilsson, Henrik Ernstson and Shuaib Lwasa on the HICCUP project have published an open access paper in the journal Urban Studies. In ‘Thinking through heterogeneous infrastructure configurations‘ case examples are used from ongoing research on sanitation and waste in Kampala, Uganda – a city in which service delivery is characterised by multiplicity, overlap, disruption and inequality – to demonstrate the heterogeneous nature of infrastructure across both formal and informal sectors. The paper argues that thinking through HICs helps us to move beyond technological and performative accounts of actually existing infrastructures to provide an analytical lens through which to compare different configurations. The approach enables a clearer analysis of infrastructural artefacts not as individual objects but as parts of geographically spread socio-technological configurations: configurations which might involve many different kinds of technologies, relations, capacities and operations, entailing different risks and power relationships. The paper reflects on how development thinking needs to better understand these conditions as a crucial step in planning for future urbanisation.
