The Colorado River Basin is just one example, albeit an extremely important one in the West, of a stressed river system. The Colorado River Basin Water Supply and Demand Study, released by the U.S. Bureau of Reclamation in late 2012, documents how growth, climate, economic development, and other factors point to an uncertain picture for communities, rural and urban alike. This policy brief highlights key questions communities should consider as they plan for their water futures.

Arizona Environmental Water Needs (AzEWN) Methodology Guidebook: Determining the best methods or quantifying environmental flow needs depends on what is to be studied as well as how the information will be used. This guidebook will provide a description of the methodologies used in Arizona to define the environment’s need for water. Depending on the geographic context, the time and effort available, and whether the goal is restoration or maintenance of an ecosystem, some methods will be more appropriate for a given application than others.

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.

Increasing demands on limited water resources have made wastewater recycling (reclamation or reuse) an attractive option for extending water supplies. Treatment technologies have evolved such that recycled water is of sufficient quality to satisfy most non-potable demands, and as such, recycled water has increasingly been used for municipal irrigation, toilet flushing, industrial cooling, and other applications. Many communities are currently engaging in discussions about the possibility of using recycled water to meet potable demands as well.

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 USA and Mexico have initiated comprehensive assessment of 4 of the 18 aquifers underlying their 3000 km border. Binational management of groundwater is not currently proposed. University and agency researchers plus USA and Mexican federal, state, and local agency staff have collaboratively identified key challenges facing the Santa Cruz River Valley Aquifer located between the states of Arizona and Sonora. The aquifer is subject to recharge variability, which is compounded by climate change, and is experiencing growing urban demand for groundwater.
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 chapter develops the story of the Central Arizona Project as an example of the large-scale, long-distance water conveyance projects that have enabled growth and development to occur in the West far from sources of water. It examines the energy implication of the CAP as well as the implications of changes and constraints in the energy industry on CAP water supplies and costs. It looks also at broader policy questions raised by the interdependencies of water and energy as embodied in the CAP.

High-volume semiconductor manufacturing (HVSM) with high demands for freshwater is often located in regions with limited water resources. This nexus of water demand and water scarcity has raised concerns among municipal governments, prompting several to consider water supply restrictions as they plan for economic growth and development. Using water use data and economic valuations of land use from Chandler, Ariz., this study compares the fiscal effect of HVSM with three alternative water uses: office, retail, and general manufacturing.

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.
