Solidarity with a sharp edge: Communal conflict and local collective action in rural Nigeria

This paper provides new insights into the link between the experience of violent conflict and local collective action. I use the temporal and geographical information from four rounds of survey data from Nigeria to relate measures of cooperation to past and future incidences of communal conflict. I show that local collective action, measured in terms of community meeting attendance and volunteering, is highest before the outbreak of vio-lence � higher than both post-conflict levels and the generally lower levels of cooperation in regions not affected by violence. I develop a �mobilisation mechanism� to explain these findings, arguing that, rather than being an indicator of �social capital�, collective action ahead of communal violence is inherently ambiguous, and driven by a form of situational-ly adaptive (and potentially aggressive) �solidarity with an edge�. I further show that the positive link between previous exposure to civil war-type violence and cooperation holds for Nigeria, too, but that it holds for rural areas only.
