President Obama and Mitt Romney meet for their third debate to discuss foreign policy on Monday, when moderator Bob Schieffer is sure to ask them about last month's terrorist attack in Libya and the nuclear capabilities of Iran.

In anticipation of the final match between the presidential candidates, researchers from five centers at Stanford’s Freeman Spogli Institute for International Studies ask the additional questions they want answered and explain what voters should keep in mind.


What can we learn from the Arab Spring about how to balance our values and our interests when people in authoritarian regimes rise up to demand freedom?  

What to listen for: First, the candidates should address whether they believe the U.S. has a moral obligation to support other peoples’ aspirations for freedom and democracy. Second, they need to say how we should respond when longtime allies like Egypt’s Hosni Mubarak confront movements for democratic change.

And that leads to more specific questions pertaining to Arab states that the candidates need to answer: What price have we paid in terms of our moral standing in the region by tacitly accepting the savage repression by the monarchy in Bahrain of that country's movement for democracy and human rights?  How much would they risk in terms of our strategic relationship with Bahrain and Saudi Arabia by denouncing and seeking to restrain this repression? What human rights and humanitarian obligations do we have in the Syrian crisis?  And do we have a national interest in taking more concrete steps to assist the Syrian resistance?  On the other hand, how can we assist the resistance in a way that does not empower Islamist extremists or draw us into another regional war?  

Look for how the candidates will wrestle with difficult trade-offs, and whether either will rise above the partisan debate to recognize the enduring bipartisan commitment in the Congress to supporting democratic development abroad.  And watch for some sign of where they stand on the spectrum between “idealism” and “realism” in American foreign policy.  Will they see that pressing Arab states to move in the direction of democracy, and supporting other efforts around the world to build and sustain democracy, is positioning the United States on “the right side of history”?

~Larry Diamond, director of the Center on Democracy, Development, and the Rule of Law


What do you consider to be the greatest threats our country faces, and how would you address them in an environment of profound partisan divisions and tightly constrained budgets? 

What to listen for: History teaches that some of the most effective presidential administrations understand America's external challenges but also recognize the interdependence between America's place in the world and its domestic situation.

Accordingly, Americans should expect their president to be deeply knowledgeable about the United States and its larger global context, but also possessed of the vision and determination to build the country's domestic strength.

The president should understand the threats posed by nuclear proliferation and terrorist organizations. The president should be ready to lead in managing the complex risks Americans face from potential pandemics, global warming, possible cyber attacks on a vulnerable infrastructure, and failing states.

Just as important, the president needs to be capable of leading an often-polarized legislative process and effectively addressing fiscal challenges such as the looming sequestration of budgets for the Department of Defense and other key agencies. The president needs to recognize that America's place in the world is at risk when the vast bulk of middle class students are performing at levels comparable to students in Estonia, Latvia and Bulgaria, and needs to be capable of engaging American citizens fully in addressing these shared domestic and international challenges.

~Mariano-Florentino Cuéllar, co-director of the Center for International Security and Cooperation


Should our government help American farmers cope with climate impacts on food production, and should this assistance be extended to other countries – particularly poor countries – whose food production is also threatened by climate variability and climate change?

What to listen for: Most representatives in Congress would like to eliminate government handouts, and many would also like to turn away from any discussion of climate change. Yet this year, U.S. taxpayers are set to pay up to $20 billion to farmers for crop insurance after extreme drought and heat conditions damaged yields in the Midwest.

With the 2012 farm bill stalled in Congress, the candidates need to be clear about whether they support government subsidized crop insurance for American farmers. They should also articulate their views on climate threats to food production in the U.S. and abroad.

Without a substantial crop insurance program, American farmers will face serious risks of income losses and loan defaults. And without foreign assistance for climate adaptation, the number of people going hungry could well exceed 15 percent of the world's population. 

~Rosamond L. Naylor, director of the Center on Food Security and the Environment


What is your vision for the United States’ future relationship with Europe? 

What to listen for: Between the end of World War II and the end of the Cold War, it was the United States and Europe that ensured world peace. But in recent years, it seems that “Europe” and “European” have become pejoratives in American political discourse. There’s been an uneasiness over whether we’re still friends and whether we still need each other. But of course we do.

Europe and the European Union share with the United States of America the most fundamental values, such as individual freedom, freedom of speech, freedom to live and work where you choose. There’s a shared respect of basic human rights. There are big differences with the Chinese, and big differences with the Russians. When you look around, it’s really the U.S. and Europe together with robust democracies such as Canada and Australia that have the strongest sense of shared values.

So the candidates should talk about what they would do as president to make sure those values are preserved and protected and how they would make the cooperation between the U.S. and Europe more effective and substantive as the world is confronting so many challenges like international terrorism, cyber security threats, human rights abuses, underdevelopment and bad governance.

~Amir Eshel, director of The Europe Center


Historical and territorial issues are bedeviling relations in East Asia, particularly among Japan, China, South Korea, and Southeast Asian countries. What should the United States do to try to reduce tensions and resolve these issues?

What to listen for: Far from easing as time passes, unresolved historical, territorial, and maritime issues in East Asia have worsened over the past few years. There have been naval clashes, major demonstrations, assaults on individuals, economic boycotts, and harsh diplomatic exchanges. If the present trend continues, military clashes – possibly involving American allies – are possible.

All of the issues are rooted in history. Many stem from Imperial Japan’s aggression a century ago, and some derive from China’s more assertive behavior toward its neighbors as it continues its dramatic economic and military growth. But almost all of problems are related in some way or another to decisions that the United States took—or did not take—in its leadership of the postwar settlement with Japan.

The United States’ response to the worsening situation so far has been to declare a strategic “rebalancing” toward East Asia, aimed largely at maintaining its military presence in the region during a time of increasing fiscal constraint at home. Meanwhile, the historic roots of the controversies go unaddressed.

The United States should no longer assume that the regional tensions will ease by themselves and rely on its military presence to manage the situation. It should conduct a major policy review, aimed at using its influence creatively and to the maximum to resolve the historical issues that threaten peace in the present day.

~David Straub, associate director of the Korea Studies Program at the Walter H. Shorentein Asia-Pacific Research Center

Paul Collier will talk about how to manage the difference between helpful and damaging commercialisation, and puts forth three arguments. First, we need to face the tough reality that African food production has failed to keep pace with demand over the course of several decades, suggesting that there is a deep problem with respect to innovation and investment given the way African agriculture has been organised. Second, we need to accept that climate change, population growth, and income gains from natural resources will all stress this imbalance further: the prospect is for widening food deficits with business as usual. Third, two major changes are afoot. Globally, the model of commercial tropical agriculture pioneered in Brazil has demonstrated that output can be raised very substantially by changing the mode of organisation. Africa is now starting to open land markets to large foreign management. Superficially this looks like Brazil2, but it may instead be a wave of speculative acquisitions triggered by the price peaks of 2008.

Collier is the Director of the Centre for the Study of African Economies and Professor of Economics and Public Policy at the Blavatnik School of Government, Oxford University. He is currently Advisor to the Strategy and Policy Department of the IMF, advisor to the Africa Region of the World Bank; and he has advised the British Government on its recent White Paper on economic development policy. He has been writing a monthly column for the Independent, and also writes for the New York Times, the Financial Times, the Wall Street Journal, and the Washington Post. His research covers the causes and consequences of civil war; the effects of aid and the problems of democracy in low-income and natural-resources rich societies.

Derek Byerlee's talk will lay out a number of models of inclusive agribusiness growth, grouped into three categories (i) institutional arrangements for improving productivity of smallholders operating in spot markets, (ii) various types of contract farming arrangements, and (iii) large-scale farms that generate jobs and/or include community equity shares. The institutional and policy context as well as commodity characteristics that favor these models are discussed within a simple transactions cost framework. He will also discuss cross-cutting policy priorities to enable the growth of commercial agriculture and agribusiness. These include continuing reforms to liberalize product and input markets, access to technology and skills, stimulating financial and risks markets, securing land rights, and investment in infrastructure through public-private partnerships. 

Byerlee has dedicated his career to agriculture in developing countries, as a teacher, researcher, administrator and policy advisor. He has lived and worked for a total of 20 years in the three major developing regions-Africa, Asia, and Latin America. After beginning in academia at Michigan State University, he spent the bulk of his career at the International Maize and Wheat Improvement Center (CIMMYT). There as a economist and research manager he made notable contributions in forging a new spirit of collaboration between scientists, economists and farmers. He also published widely on efficiency of research systems, spillovers, and sustaining productivity in post green revolution agriculture. After joining the World Bank in 1994, he has applied his experience of research systems to finding innovative approaches to funding and organizing agricultural research, including emerging challenges in biotechnology policy. Since 2003, he has provided strategic direction and led policy world for the agricultural and rural sector in the World Bank.

Soybean production has become a significant force for economic development in Brazil. It has also received considerable attention from environmental and social non-governmental organizations as a driver of deforestation and land consolidation. While many researchers have examined the impacts of soybean production on human and environmental landscapes, there has been little investigation into the economic and institutional context of Brazilian soybean production or the relationship between soy yields and planted area. This study examines the influence of land tenure, land use policy, cooperatives, and credit access on soy production in Brazil. Using county level data we provide statistical evidence that soy planted area and yields are higher in regions where cooperative membership and credit levels are high, and cheap credit sources are more accessible. This result suggests that soybean production and profitability will increase as supply chain infrastructure improves in the Cerrado and Amazon biomes in Brazil. The yields of competing land uses, wheat, coffee, and cattle production and a complementary use, corn production, also help to determine the location of soybean planted area in Brazil. We do not find a significant relationship between land tenure and planted area or land tenure and yields. Soy yields decline as transportation costs increase, but planted area as a proportion of arable land is highest in some of the areas with very high transportation costs. In particular, counties located within Mato Grosso and counties within the Amazon biome have a larger proportion of their arable, legally available land planted in soy than counties outside of the biome. Finally, we provide evidence that soy yields are positively associated with planted area, implying that policies intending to spare land through yield improvements could actually lead to land expansion in the absence of strong land use regulations. While this study focuses on Brazil, the results underscore the importance of understanding how supply chains influence land use associated with cash crops in other countries.

For all of the talk about the need to adapt to climate change, we still know fairly little about two basic questions: what works best, and how much can adaptation deliver? It‘s time to learn quickly.

Why don’t we know more? It would be easy to blame our ignorance on complacency. There is a tendency to marvel at the progress made in agriculture in the past 50 years, and assume it can handle anything. For example, the USDA declared in the early 1970s that new technologies meant “man has reduced variation in yields in both good and bad weather.” This optimism quietly faded after a series of bad harvests in the late 1970’s and 1980’s, including the big drought of 1988. People realized that a period of unusually benign weather, and not the technological gains themselves, had limited volatility during the middle of the 20th century.

It is also tempting to blame ignorance on inexperience. After all, many people continue to view climate change as something to deal with in the future. But the evidence is clear that climate has already been changing over the past 30 years in most agricultural areas, and farmers are doubtlessly trying to adapt. Up until now, the United States was an exception to that trend. But the 2012 drought has changed that, and projections indicate that years like this will be increasingly common in the coming decades.

With widespread evidence for climate change and its impacts, complacency and inexperience should give way to rigorous evaluations of what has happened. For example, why was US agriculture not better prepared for the 2012 drought? And did anything work well that can be scaled up?

A lot has changed in US agriculture since the 1988 drought, and many of the changes were textbook examples of what should help to reduce impacts of hot summers. Farmers now sow corn and soybeans more than a week earlier on average, and use longer maturing varieties than in 1988. Advances in cold tolerance along with spring warming trends allowed corn to expand in northern states where temperatures are cooler. For example, North and South Dakota increased corn area by more than 35% (nearly 2.5 million acres) just since 2009. Carbon dioxide levels, which improve crop water use efficiency, have increased by more than 10% since 1988. And farmers have begun to grow drought tolerant seeds that were unavailable in 1988.

Yet when the 2012 drought arrived, with fairly similar characteristics to 1988, impacts on crop yields were roughly the same. Corn yields are expected to be about 25% below trend, close to the 28% drop in 1988.

What can we learn from this experience? It is too early to say anything definitive, but two explanations seem plausible. First, it may be that some of the above changes were truly beneficial, but were counteracted by other changes making agriculture more, not less, sensitive to weather. For example, breeding progress in corn has generally been faster for good conditions than bad. As farmers become even better at eliminating yield losses from pests, nutrient stress, and other factors, the benefits of having favorable rainfall and temperature become that much greater, and the relative damages of not having them become that much worse.

A second possibility, of course, is that the adaptive changes in agriculture simply did not help much in dealing with adverse weather. For example, migrating corn northward may help, but the vast majority of corn production remains where it has been for decades, so the quantitative effect is small.

Hopefully researchers will quickly distinguish between these and other explanations, and the lessons can help guide efforts to further adapt. But any explanation will likely imply that there are limits to how much adaptation can reduce impacts of climate change. This fact does not diminish the urgency and importance of efforts to adapt to climate variability and change throughout the world. But it is a reminder that greenhouse gas mitigation is pivotal in any strategy to reduce impacts of climate change. Adaptation can only do so much.

Sharon Gourdji, postdoctoral scholar at Stanford's Center on Food Security and the Environment, has been awarded a Fulbright Scholar grant to assess climate change adaptation strategies for maize-bean smallholder farmers in Central America during the 2012-2013 academic year. This will be a collaboration with the International Center for Tropical Agriculture (CIAT) in Cali, Colombia and with a global cross-CGIAR initiative called Climate Change and Food Security.

Proposal abstract:

Maize and bean production provides a livelihood for millions of subsistence-level farmers in Central America. However by 2050, projected climate change threatens the viability of maize-bean production in the region, with some areas becoming completely unsuitable, and others suitable only with sufficient agronomic adaptations. In this proposal, we first assess the impact that climate trends have had on yields and farmer livelihoods in the last 30 years. Next, we look at two adaptation strategies to help farmers cope with future changes: the development and spread of more heat and drought-tolerant varieties, especially for bean, and the uptake of small-scale irrigation to cope with unreliable rainfall and expand production into the dry season.

About the Fullbright NEXUS program:

The Fulbright NEXUS program this year is focused on sustainable development in the Western Hemisphere (http://www.cies.org/NEXUS/). Gourdji is one of approximately 1,100 U.S. faculty and professionals who will travel abroad through the Fulbright U.S. Scholar Program in 2012-2013.

The Fulbright Program is the flagship international educational exchange program sponsored by the U.S. government and is designed to increase mutual understanding between the people of the United States and the people of other countries. The primary source of funding for the Fulbright Program is an annual appropriation made by the U.S. Congress to the U.S. Department of State, Bureau of Educational and Cultural Affairs. Participating governments and host institutions, corporations and foundations in foreign countries and in the United States also provide direct and indirect support. Recipients of Fulbright grants are selected on the basis of academic or professional achievement, as well as demonstrated leadership potential in their fields. The Program operates in over 155 countries worldwide.

Her research focuses on the impacts of globalization on land use, with particular attention to tropical commodities.  She has extensive experience on rural development and environmental conservation in Latin America. Ximena received a BA and MA in Economics from Universidad de los Andes in Colombia, a Masters in City Planning from MIT, and a PhD in Geography from Clark University.

The Yaqui Valley is the birthplace of the Green Revolution and one of the most intensive agricultural regions of the world, using irrigation, fertilizers, and other technologies to produce some of the highest yields of wheat anywhere. It also faces resource limitations, threats to human health, and rapidly changing economic conditions. In short, the Yaqui Valley represents the challenge of modern agriculture: how to maintain livelihoods and increase food production while protecting the environment.
