Throughout history, and at both the local and international levels, attempts to resolve water disputes have often focused on augmenting the water supply. The assumption has been that scarcity drives conflict, and that disputes can be “diluted” by increasing the amount of water, through desalination, cloud-seeding, water pipelines, or other methods of water augmentation. However, when water augmentation has inequitable impacts, or where water itself is merely a symbol of a different dispute (over sovereignty, for example), water augmentation can make disputes more contentious. This presentation will discuss the promise and pitfalls of a “water dispute dilution” approach in disputes between refugees and host communities, between indigenous peoples and neighboring communities, and in basin-wide disputes in the Colorado River Basin and Jordan River Basin. The goal of this discussion is to understand when and why water augmentation may aggravate or mitigate water disputes.
