Science, Technology, and Public Policy

An estimated 14,485 nuclear weapons exist on earth today — most are far more powerful than those that twisted railway ties, leveled buildings, and crushed, poisoned, and burned human beings in Hiroshima and Nagasaki. The majority of these weapons belong to the United States and Russia. For some in the U.S. government, including Chris Ford, assistant secretary at the State Department’s Bureau of International Security and Nonproliferation, this number represents significant disarmament progress since Cold War highs of over 70,000 nuclear weapons. They argue the current security environment means that further reductions are not possible at this time. In contrast, for many disarmament advocates and officials from non-nuclear weapons states, this number is still far too high. They are now clamoring to ban all nuclear weapons. Because of this divide, according to Ford, we currently face a “disarmament crisis.”

Water, energy, and food security are of critical concern as rising population growth and rapid urbanization place greater pressure on our natural resources. This study evaluates the growing internationalization of food production in water-scarce countries using the case of Saudi Arabia as a microcosm to illustrate the tradeoffs in resource consumption associated with crop selection and farming practices.

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.

The Spring 2011 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 the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.

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.
