Asia & the Pacific

Last October, at the foot of a rocky hillside near here, at a spot known as Degelen Mountain, several dozen Kazakh, Russian and American nuclear scientists and engineers gathered for a ceremony. The modest ribbon-cutting marked the conclusion of one of the largest and most complex nuclear security operations since the Cold War — to secure plutonium (enough to build a dozen or more nuclear weapons) that Soviet authorities had buried at the testing site years before and forgotten, leaving it vulnerable to terrorists and rogue states. The effort spanned 17 years, cost $150 million and involved a complex mix of intelligence, science, engineering, politics and sleuthing. This op-ed is based on documents and interviews with Kazakh, Russian and U.S. participants, and reveals the scope of the operation for the first time.

"The tools available to India in the 1960s are not sufficient to address the challenges that African agriculture now faces. These include a rapidly-growing population, productivity loss due to ecological disruption, environmental decay, droughts, climate change, and conflict. Biotechnology offers additional tools that can help Africa address some of these challenges. It is another moment that calls for the kind of political courage that led to the adoption of the Green Revolution."
