Incremental infrastructures: material improvisation and social collaboration across post-colonial Accra

Approaching the informal construction and extension of infrastructures through the terrain of what I term “the incremental” opens up new platforms of analysis for post-colonial urban systems. This refers to ad hoc actions on the part of slum dwellers to connect to energy networks or carve out informal living spaces. I argue that incrementalism is produced and subsequently secured and scaled through material configurations that seek to test and prefigure new forms of infrastructure and accompanying resource flows. I use a case study of energy and housing systems in a low-income neighborhood in Accra to define and examine these incremental infrastructures. I examine shifts in the Accra energy network as urban dwellers rework connections to flows of electricity. I also consider the material adjustment of housing and the role of cooperation in responding to threats of demolition and displacement. Together, incremental infrastructures and the ways that they are constituted articulate a prefigurative politics in which residents seek to generate access to new infrastructural worlds.
