Science, Technology, and Public Policy

We here introduce the idea of highly decentralized solar geoengineering, plausibly done in form of small high-altitude balloons. While solar geoengineering has the potential to greatly reduce climate change, it has generally been conceived as centralized and state deployed. Potential highly decentralized deployment moves the activity from the already contested arena of state action to that of environmentally motivated nongovernmental organizations and individuals, which could disrupt international relations and pose novel challenges for technology and environmental policy. We explore its feasibility, political implications, and governance.

Based on satellite imagery, Chinese publications, and discussions with Chinese experts, This report suggests that China has much more civilian enrichment capacity than previously thought, and even more is on the way. If these new estimates are correct, China has enough enrichment capacity to meet its nuclear power fuel requirements for the coming decade and beyond. Further, China will have excess enrichment capacity and will likely become a net exporter of commercial enrichment services.

As Africa's position in the world continues to grow and evolve in 2014, the Brookings Africa Growth Initiative continues its tradition of asking its experts and colleagues to identify what they consider to be the key issues for Africa in the coming year.

Calestous Juma and Katherine Gordon argue that biotechnology has the potential to exponentially raise Africa's agricultural production, increase food security, drive economic growth and save African farmers millions of dollars.

What will be the shape of the internet in 20 years? The authors explore possible futures in global cyber security governance and recommend a robust set of actions that pave a path forward towards establishing an environment in which a more cooperative form of global cyber security governance could evolve.

"The military buildup by China, its Asia-Pacific neighbors and the United States is creating a classical security dilemma that is increasing the potential for military conflict in the region. Although history is replete with conflicts between existing and rising powers, conflict between China and the United States is not preordained. Opportunities exist in both the diplomatic and military arenas for both countries to actively engage the other in open and direct communication to increase transparency, reduce tensions, and improve understanding. It is in the best interest of the United States, China and countries around the world to confront the reality that is a rising nuclear-armed China and, in doing so, manage its accession into the regional and world order without conflict."

The unconventional fossil fuel extraction industry—in the U.S., primarily shale gas and tight oil—is expected to continue expanding dramatically in coming decades as conventionally recoverable reserves wane. At the global scale, a long-term domestic supply of natural gas is expected to yield environmental benefits over alternative sources of fossil energy. At the local level, however, the environmental impacts of shale gas and tight oil development may be significant. The development of technology, management practices, and regulatory policies that mitigate the associated environmental impacts of shale gas development is quickly becoming the next frontier in U.S. unconventional fossil resource extraction.

South Korea faces a complex security environment that increasingly has important maritime components, a situation that produces many competing priorities from coastal defense against North Korea to regional concerns, and finally to global protection of sea lanes and contributing to humanitarian assistance and disaster relief operations. Consequently, concerns for China are only one piece of the ROK Navy's strategy and force planning decisions.
