In contrast, examples of conflict and cooperation between the U.S. and Mexico show that despite having the IBWC as an intergovernmental body designated by treaty to deal with water issues, conflicts still arise. While some of these conflicts are easy to solve, such as those dealing with surface water quality, others are not as easy and deal with the eventual necessity of apportioning transboundary groundwaters. In many of these cases, the arid climate, growing population, and recent prolonged drought have made water appear even scarcer. North America’s vulnerability and resilience in the face of transboundary water conflicts is guided by the institutions that have been created to assist with water resources issues along both major borders of this continent. Each institution has specific functions due to geography and climate—the lack of or abundance of water dictates how the treaties were written and their flexibility in light of the fact that the borders themselves cross many climatic and geographic zones. The political boundaries divide many transboundary waterways and subterranean water resources.
