Arizona Environmental Water Needs Assessment (AzEWNA) Report: Considering environmental water needs alongside human demands is an emerging paradigm in water policy. The science of environmental water needs (or e‐flows) is ever growing and evolving. And yet, no compendium of efforts to define e‐flows in Arizona had been compiled,until now. This Assessment Report describes the geographic location and focus of nearly 100 studies of environmental water needs in Arizona, using all relevant sources.

This bulletin provides a concise introduction to the current knowledge about environmental water demands in the North/Northeastern Arizona Region.  It outlines gaps in the understanding of environmental demands and illustrates how environmental demands can be considered in the context of other regional water demands.  There are four bulletins in this series, Central Arizona, Southeastern Arizona, Colorado River and North/Northeastern Arizona.

This bulletin provides a concise introduction to the current knowledge about environmental water demands in the Colorado River Region. It outlines gaps in the understanding of environmental demands and illustrates how environmental demands can be considered in the context of other regional water demands. There are four bulletins in this series, Central Arizona, Southeastern Arizona, Colorado River and North/Northeastern Arizona.

Governance is an immense conceptual construct, encompassing a suite of precepts, principles, ideas, theories, contexts, objectives, and practices. The FAO/ GEF project “Groundwater Governance: A Global Framework for Country Action” is a comprehensive attempt to understand and articulate this notion in its entirety—as applied to the particular subject of groundwater.

In 2009, Arizona Governor Jan Brewer announced the formation of the Blue Ribbon Panel on Water Sustainability (BRP) to focus on water conservation and recycling as strategies for improving water sustainability in Arizona.

Sustainable water management is a critical concern in the semi-arid portions of the American Southwest. This paper explains the decentralized approach to water supply management in this region, including the traditional roles of the public and private sectors. With Arizona as a focus, it explores how the water supply challenges of the twenty-first century require new approaches and partnerships for funding infrastructure, obtaining new water supplies, water banking, and water treatment.

The fourth edition of the World Water Development Report (WWDR4), ‘Managing Water under Uncertainty and Risk’ was recently launched at the 6th World Water Forum in Marseille by Irina Bokova, UNESCO Director General, and Michel Jarraud, UN-Water Chair. The WWDR4 is a comprehensive review of the world's freshwater resources and seeks to demonstrate, among other messages, that water underpins all aspects of development, and that a coordinated approach to managing and allocating water is critical.

This article describes the WRRC’s Conserve to Enhance (C2E) Tucson pilot project from concept to implementation and preliminary results. C2E aims to connect conservation actions with water for the environment by developing mechanisms for funding water-related environmental enhancements. The Tucson pilot demonstrates the challenges and opportunities of making this concept a reality.

Setting water policy depends fundamentally on the location of the supply and demand for water and the legal/institutional framework for water management. Within and across nations, laws and structures for water management decision making vary, often significantly. Recognizing these differences can aid in overcoming challenges inherent to the assessment and management of transboundary waters. This paper examines current binational efforts to develop the scientific information to support water management decision making along the United States-Mexico border.

This Morrison Institute for Public Policy report examines water use, supply and future demand for Arizona's Sun Corridor - the Central Arizona Urban Region that includes Phoenix and Tucson.

Integrated management of trasnboundary rivers and aquifers is a major challenge. This article reviews some of these challenges and the cooperation that has resulted to address these issues.
