To what extent do marine-based economic activities influence the onset of violent conflict?Despite ongoing debate over several decades around the relationship between naturalresources and violent conflict, little of the relevant research has addressed the marineenvironment. Based on satellite data in Indonesia, this paper provides new evidence on therelationship between fisheries and violent conflict. From a sample of 757 cells representingthe spatial interaction of conflict and catch landings in 2015 and employing oceanproductivity as an exogenous instrument, both industrial and non-industrial catches werefound to have a statistically significant positive effect on the number of conflict events.Additionally, increased illegal, unreported and unregulated (IUU) catches are more likelythan legal catches to cause violent conflict. An increase in fish catches in Indonesian watersfuels conflict of every kind, among which protests and riots are most sensitive to fisherieswhile fighting and terrorism are least sensitive. Overall, these empirical findings support thehypothesis that increased competition for common-pool resources contributes to the onset ofviolent conflict.
