African SecurityOlivier J. Walther, et. al
2021-11-08
Contemporary conflict in North and West Africa is characterized by a high degree of social and political complexity. Hundreds of rebel groups and extremist organizations are involved in a shifting series of alliances and rivalries with regional governments and with each other. These changing relationships can be represented as a social network that provides both opportunities and constraints to violent organizations.

While the location of violent events and their propensity to cluster together is increasingly well known, a deeper exploration of their spatiality and spatial evolution over time remains an emerging frontier in “Big Data”-driven conflict studies. The new Spatial Conflict Dynamics indicator (SCDi) introduced in this article contributes to fill this gap, by measuring both the intensity and spatial concentration of political violence at the subnational level.
Contextualizing the Relationship Between Borderlands and Political Violence: A Dynamic Area-Time Analysis in North and West Africa

They are also essential to efforts by non-state groups to bypass or challenge the same. However, not all borderlands are the same and the evolution of conflict is a complex and dynamic process.
