Rivers of Discontent: Indicators of Water Conflict in Interstate River Basins of The American Southwest

Abstract

Conflicts over the optimal allocation of water resources are no longer just a concern but political reality. Increasing population and demands, competing uses, as well as uncertainty over scientific processes all add to the complexity of water management and in turn can lead to complex, difficult, and long standing water conflicts. This research employs Geographic Information Systems (GIS) to evaluate water conflict in interstate settings and examines the relationship between commonly held conceptions of water conflict and actual events. Results reveal a low number of observations in each of the examined basins. Each basin has a unique relationship with the evaluated variables and the use of GIS reveals distinct spatial relationships for conflicts. However, the modifiable unit areal problem presents a real concern for continued application. Results also reveal that generalizing indicators of conflict across basins loses the inherent variability and nuanced relationships that are seen through a basin-by-basin analysis.
