Summary
The border region between the United States and Mexico has fostered its share of surface-water conflict, from the Colorado River to the Rio Grande/Rio Bravo River. It has also been a model for peaceful conflict resolution, notably the work of the International Boundary and Water Commission (IBWC), the supra-legal body established to manage shared water resources as a consequence of the 1944 US-Mexico Water Treaty. Yet the difficulties encountered in managing shared surface-water pale in comparison to trying to allocate groundwater resources-each aquifer system is generally not understood as gathering information on aquifers is very costly and the science of groundwater is still inexact. This makes negotiations over a shared aquifer system very difficult. The complications of groundwater are exemplified in the border region between the United States and Mexico where, despite the presence of an active supra-legal authority since 1944, groundwater issues have yet to be resolved. Mentioned as vital in the 1944 Treaty, and again in 1973, the difficulties in quantifying the ambiguities inherent in groundwater regimes has eluded legal and management experts ever since. Even after three decades of having problems with the 1944 Treaty and groundwater issues, there does not appear to be a movement towards a new agreement referring to the United States-Mexican shared aquifers anytime soon, although Mumme[1] states that it is likely that "some form of systematic cooperation will emerge" between stakeholders in more local areas along the border.
