Geography as Motivation and Opportunity: Group Concentration and Ethnic Conflict

Abstract

The literature suggests that geographically concentrated groups face a higher likelihood of conflict. While this finding seems to be commonly accepted, there is no clear consensus that explains why this is the case. Two competing mechanisms have been proposed: first, a motivation-driven mechanism, where the existence of a well-defined group territory makes the group more likely to fight for it; and second, an opportunity-driven link, where concentration facilitates group coordination for collective action. This article aims to resolve this controversy by developing new settlement pattern indicators based on Geographic Information Systems (GIS) data. Using conflict data at the level of ethnic groups, I show that there is clear evidence in favor of the opportunity mechanism. Thus, the effect of group concentration on conflict seems to be driven by the strategic advantages for group coordination that the spatial proximity of group members provides.
