Many consider gravity-flow irrigation inefficient and deride its use. Yet, there are cases where gravity-flow irrigation can play an important role in highly productive and profitable agriculture. This perspective article reviews the literature on the profitability and efficiency of gravity systems. It then reviews the history of water management in Yuma, Arizona, which is one of the most productive agricultural areas in the United States.
Membership on the Transboundary Aquifer Assessment Program (TAAP) team continues to be gratifying. The late 2016 publication of the Binational Study of the Transboundary San Pedro Aquifer by the International Boundary and Water Commission marked a milestone. This study is noteworthy in that it is a first-ever binationally prepared, fully bilingual aquifer assessment along the border shared by the United States and Mexico, and because it was subject to peer review on both sides of the border.

This Special Issue of Water will focus on the relationship of water governance practices and stakeholder engagement approaches to the development, evaluation, and adoption of solutions to water management challenges. It is well recognized that the human dimensions of considering alternative water management scenarios and policy options are as least as important as their engineering, hydrological, and financial aspects.
