Justifying a conflict over the Guarani Aquifer

This article deals with the justification of water-related conflicts by analyzing a hypothetical war for Guarani Aquifer resources. In disagreement, a theoretical framework would be needed to justify war. First, Walzer’s version of Just War Theory (JWT) is presented as the most consolidated reference. Then, Waddington’s criticism of JWT is discussed when it comes to hydric resources, delineating the particularities of a natural resource and establishing that the “moral weight of water scarcity” should be considered. Following this, the hypothetical conflict among countries is introduced. Finally, pragmatism is advocated for justification of conflicts involving water.
