Environment & Climate Change

In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

"The rise of nations such as South Korea, Singapore and China as global economic players illustrated the importance of expanding and deepening human competence. A key starting point in the growth process is recognising that building engineering capabilities offered the best opportunity for technological leapfrogging and catch-up in a variety of industries."

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

"Values Conscious design may not be able to prevent the kind of deliberate fraud perpetrated by Volkswagen, but it could well have revealed Volkswagen's design choices as dubious, to say the least."

Cambridge, MA – The Belfer Center for Science and International Affairs has named Daniel Schrag, Sturgis Hooper Professor of Geology and Director of the Center for the Environment at Harvard University, to lead its Science, Technology, and Public Policy program. STPP, one of Harvard's most collaborative and cross-disciplinary programs, is renowned world-wide for its cutting-edge research on technology innovation, nuclear non-proliferation and safety, climate science and policy, cybersecurity, and globalization and development.

The New Harvest argues that Africa can feed itself in a generation and help contribute to global food security despite its history of persistent food shortages and the rising threat of climate change. This new edition provides ideas on how to place agriculture at the center of the continent's long-term economic transformation. It demonstrates how policy coordination can help realize agriculture's full potential as a motherboard for other economic activities.
