International Water Cooperation and Environmental Peacemaking

Proponents of the environmental peacemaking approach argue that environmental cooperation has the potential to improve relations between states. This is because such cooperation facilitates common problem solving, cultivates interdependence, and helps to build trust and understanding. But as of now, very few cross-case studies on environmental peacemaking exist. Furthermore, much of the available literature understands peace in negative terms as the mere absence of acute conflict. This article addresses both shortcomings by studying the impact of international water cooperation on transitions toward more peaceful interstate relations. To do so, we combine information on positive water-related interactions between states with the peace scale, a recent data set measuring the degree of positive and negative peace between states. For the period 1956–2006, we find that a higher number of positive, water-related interactions in the previous ten years makes a shift toward more peaceful interstate relations more likely. This is particularly the case for state pairs that are not in acute conflict with each other.
