In this research paper, the authors propose that future human mediated water availability in arid regions may be assessed by considering key projects that have been identified or proposed by regional experts and organizations. Using Multicriteria Decision Methods as a framework to organize a set of decision criteria and their relative salience, the likelihood of selection (and development) of a project can be determined and used to form expectations of future regional water availability. The authors apply this approach in a case study of Jordan.

Water resources development options are usually selected on a least-cost basis. While economic considerations are dominant in choosing projects, there are also a mix of other factors including social demands, political expediency, social equity, and environmental considerations that impact final decisions and development of water supply systems. Understanding local priorities in water resource management decisions can allow for forming expectations of future regional water availability. In this research, the authors propose that future water availability in arid regions may be assessed by considering key projects that have been identified or planned by regional experts.

With a team of scientists, engineers, and political scientists, the Center’s Science, Technology, and Public Policy Program (STPP) and Energy Technology Innovation Policy group (ETIP) are tackling critical global issues related to energy challenges and water-energy connections. During the past few months, STPP/ETIP faculty, fellows, and visiting scholars have conducted research, made presentations, and held high-level discussions in the U.S., China, and the Gulf region.The work is a joint effort of STPP and the Belfer Center’s Environment and Natural Resources Program (ENRP) along with Harvard Kennedy School’s Sustainability Science Program.

Saudi Arabia is the third-largest per capita water user worldwide and has addressed the disparity between its renewable water resources and domestic demand primarily through desalination and the abstraction of non-renewable groundwater. This study evaluates the potential costs of this approach in the industrial and municipal sectors, exploring economic, energy, and environmental costs (including CO2 emissions and possible coastal impacts). Although the energy intensity of desalination is a global concern, it is particularly urgent to rethink water supply options in Saudi Arabia because the entirety of its natural gas production is consumed domestically, primarily in petrochemical and desalination plants.

Industrial and urban water reuse should be considered along with desalination as options for water supply in Saudi Arabia. Although the Saudi Ministry for Water and Electricity (MoWE) has estimated that an investment of $53 billion will be required for water desalination projects over the next 15 years [1], the evolving necessity to conserve fossil resources and mitigate GHG emissions requires Saudi policy makers to weigh in much more heavily the energy and environmental costs of desalination. Increasing water tariffs for groundwater and desalinated water to more adequately represent the costs of water supply could encourage conservation, but also reuse, which may be more appropriate for many inland and high-altitude cities.

Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called 'water–energy nexus', is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the MENA region.

The Winter 2010/11 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights a major Belfer Center conference on technology and governance, the Center's involvement in the nuclear threat documentary Countdown to Zero, and a celebration of Belfer Center founder Paul Doty.

"...[S]ince sanctions and economic constraints will directly impact ordinary Iranians, they will intensify the current sense of distrust towards the West and especially the United States in all political trends and people, subsequently resulting in national mobilization and unity, thereby strengthening the hand of the Iranian government to resist the sanctions. This is the complete opposite of the result desired by the West."
