Conflict management of riparian disputes

This paper builds on a large literature that explores the linkages between resource scarcity and interstate conflict. Focusing on competing claims over cross-border rivers, we analyze peaceful and militarized techniques used by states to manage river claims, and compare the success of these techniques for resolving the issues under contention. We focus on two key factors to account for variance in the use and effectiveness of conflict management strategies: water scarcity and institutions. We argue that high levels of water scarcity increase the frequency of explicit claims over fresh water, increase the chances of militarized conflict over these claims, and make it more difficult for conflict management institutions to be created or to be effective. We also examine the role of peace-promoting institutions, both river-specific and general institutions, arguing that institutional membership should promote peaceful attempts to resolve river claims. Analyzing data on river claims (1900–2001) from the Issue Correlates of War (ICOW) Project, we find that greater water scarcity increases the likelihood of both militarized conflict and peaceful third party settlement attempts, while river-specific institutions reduce militarized conflict and increase the effectiveness of peaceful settlement attempts.
