A discussion paper by Robyn Johnston, Michael Roberts, Thuon Try and Sanjiv de Silva on groundwater for irrigation in Cambodia, published by International Water Management Institute, Colombo, Sri Lanka, iDE Cambodia in June 2013.

The Arizona Water Settlements Act of 2004 ended nearly four decades of water disputes between the Gila River Indian Community and the state of Arizona. This paper explores the historical background of the Gila River Indian Community and its claim to water rights, the evolution of tribal water rights laws that culminated in the historic settlement, and the consequences of the act on water resource management in the region. It also links the findings from this case to the broader field of indigenous water rights studies from other regions of the world.
