This paper provides an analysis of a broadband implementation in the town of Slavutych, Ukraine. Slavutych was purposefully built 50 km from Chernobyl shortly after the Chernobyl Nuclear Power Plant (ChNPP) disaster in 1986 to house personnel of ChNPP and their families evacuated from the city of Prip'yat. Drawing on activity theory, and in particular the notion of activity systems, we demonstrate how an activity system approach can be used to frame Information and Communication Technology for Development (ICTD) intervention. We highlight the tools used to mediate the activity, the activity motivation and the relevant stakeholders and examine the role of ‘contradictions’. Using the notion of connected activities, we also provide some theoretical basis for understanding the emergence of activities and conceptualising the impact of development projects, arguing that the outcome of an activity leads to/is consumed by other related activities. This paper contributes to scholarship in the field of ICTD using an empirical case in a complex setting and furthers theoretical development by advancing an activity system perspective for understanding and theorising ICTD interventions.
