"Sustaining African agricultural transformation will require national policy approaches which emphasize the need to transition toward sustainable agriculture. More specifically, they will need to pursue strategies that allow for the integration of precision agriculture in existing farming methods. Such policies could focus on six key elements: biological diversity; ecology and emerging technologies; infrastructure; research and training; entrepreneurship and regional trade; and improved governance of agricultural innovation."

As assistant to the president for science and technology, director of the White House Office for Science and Technology Policy, and co-chair of the President’s Council of Advisors on Science and Technology (PCAST), Holdren has worked closely with Obama to reinvigorate America’s scientific capabilities on a range of policy fronts, from climate change and renewable energy to health care and nanotechnology.

Scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere.

International trade has become the fastest growing driver of global carbon emissions, with large quantities of emissions embodied in exports from emerging economies. International trade with emerging economies poses a dilemma for climate and trade policy: to the extent emerging markets have comparative advantages in manufacturing, such trade is economically efficient and desirable. However, if carbon-intensive manufacturing in emerging countries such as China entails drastically more CO2 emissions than making the same product elsewhere, then trade increases global CO2 emissions.

The magnitude and growing annual rate of growth of China's carbon emissions make this country the major driver of global carbon emissions and thus a key focus for efforts in emissions mitigations. This report presents independent data on China's carbon emissions from 1950–2012, and provides a basis to support mitigation efforts and China's low-carbon development plan.

"An ambitious deal might also stimulate more demand for innovations in clean technologies, in which China is emerging as a global leader. But because of the UN's decision-making process, in which all its members have to agree on a new deal, Xi Jinping is in the powerful position of being able to commit to only as much emission reductions as fit his domestic policy agenda."

"To harness the globally available technologies, African leaders will need to take into account the multisectoral dimension of African agriculture and pay particular attention to the urgency of investing in rural infrastructure, higher agricultural training and creation of regional markets."
