In a recent speech, Stanford professor Rosamond Naylor examined the wide range of challenges contributing to global food insecurity, which Naylor defined as a lack of plentiful, nutritious and affordable food. Naylor's lecture, titled "Feeding the World in the 21st Century," was part of the quarterly Earth Matters series sponsored by Stanford Continuing Studies and the Stanford School of Earth Sciences. Naylor, a professor of Environmental Earth System Science and director of the Center on Food Security and the Environment at Stanford, is also a professor (by courtesy) of Economics, and the William Wrigley Senior Fellow at the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment.

"One billion people go to bed day in and day out with chronic hunger," said Naylor. The problem of food insecurity, she explained, goes far beyond food supply. "We produce enough calories, just with cereal crops alone, to feed everyone on the planet," she said. Rather, food insecurity arises from a complex and interactive set of factors including poverty, malnutrition, disease, conflict, poor governance and volatile prices. Food supply depends on limited natural resources including water and energy, and food accessibility depends on government policies about land rights, biofuels, and food subsidies. Often, said Naylor, food policies in one country can impact food security in other parts of the world. Solutions to global hunger must account for this complexity, and for the "evolving" nature of food security.

As an example of this evolution, Naylor pointed to the success of China and India in reducing hunger rates from 70 percent to 15 percent within a single generation. Economic growth was key, as was the "Green Revolution," a series of advances in plant breeding, irrigation and agricultural technology that led to a doubling of global cereal crop production between 1970 and 2010. But Naylor warned that the success of the Green Revolution can lead to complacency about present-day food security challenges. China, for example, sharply reduced hunger as it underwent rapid economic growth, but now faces what Naylor described as a "second food security challenge" of micronutrient deficiency. Anemia, which is caused by a lack of dietary iron and which Naylor said is common in many rural areas of China, can permanently damage children's cognitive development and school performance, and eventually impede a country’s economic growth.

Hunger knows no boundaries

Although hunger is more prevalent in the developing world, food insecurity knows no geographic boundaries, said Naylor. Every country, including wealthy economies like the United States, struggles with problems of food availability, access, and nutrition. "Rather than think of this as 'their problem' that we don't need to deal with, really it's our problem too," Naylor said.

She pointed out that one in five children in the United States is chronically hungry, and 50 million Americans receive government food assistance. Many more millions go to soup kitchens every night, she added. "We are in a precarious position with our own food security, with big implications for public health and educational attainment," Naylor said. A major paradox of the United States' food security challenge is that hunger increasingly coexists with obesity. For the poorest Americans, cheap food offers abundant calories but low nutritional value. To improve the health and food security of millions of Americans, "linking policy in a way that can enhance the incomes of the poorest is really important, and it's the hard part,” she said.” It's not easy to fix the inequality issue."

Success stories

When asked whether there were any "easy" decisions that the global community can agree to, Naylor responded, "What we need to do for a lot of these issues is pretty clear, but how we get after it is not always agreed upon." She added, "But I think we've seen quite a few success stories," including the growing research on climate resilient crops, new scientific tools such as plant genetics, improved modeling techniques for water and irrigation systems, and better knowledge about how to use fertilizer more efficiently. She also said that the growing body of agriculture-focused climate research was encouraging, and that Stanford is a leader on this front.

Naylor is the editor and co-author of The Evolving Sphere of Food Security, a new book from Oxford University Press. The book features a team of 19 faculty authors from 5 Stanford schools including Earth science, economics, law, engineering, medicine, political science, international relations, and biology. The all-Stanford lineup was intentional, Naylor said, because the university is committed to interdisciplinary research that addresses complex global issues like food security, and because "agriculture is incredibly dominated by policy, and Stanford has a long history of dealing with some of these policy elements. This is the glue that enables us to answer really challenging questions." 

According to a new study co-authored by Stanford professor David Lobell, the chance of a worldwide slowdown in agricultural yield growth in the next two decades is significantly higher due to global warming.

Lobell and co-author Claudia Tebaldi, a senior researcher at the National Center for Atmospheric Research, set out to estimate the odds of a steep drop in global wheat and corn yield progress under several climate scenarios. The study, “Getting caught with our plants down: the risks of a global crop yield slowdown from climate trends in the next two decades” appeared in Environmental Research Letters.

Lobell said he was motivated to pursue the study based on questions posed by stakeholders and decision makers in governments and the private sector.

“I’m often asked whether climate change will threaten food supply, as if it’s a simple yes or no answer,” Lobell said. “The truth is that over a 10 or 20 year period, it depends largely on how fast the Earth warms, and we can’t predict that very precisely. So the best we can do is try to determine the odds.”

Lobell and Tebaldi calculated the chance of a 10 percent global yield loss from climate change over the next 20 years, which would represent a severe impact on food supply, enough to roughly halve the rate of yield growth.

The short time frame of the study was deliberate, Lobell said. “Many studies have looked at climate and agriculture trends over the coming 50 or 100 years. But the next two decades are when most of the global population growth, and dietary shifts driven by a growing middle class, will occur. The growth rate of food demand will be higher during this time than at any other time in the next century.”

Without human-induced global warming – in other words, in a world with only natural climate variability – the likelihood of a yield drop that large is only 1 in 200. But when the team accounted for global warming, they saw the odds jump to 1 in 10 for corn and 1 in 20 for wheat. “In this study, we did not try to estimate the most likely impacts of climate change on crops,” Lobell said. “Rather, we estimated the likelihood of a really major impact, not because we want to scare people, but because there are many people who want to be prepared for all contingencies.”

“The point of the paper is to move from hand-waving about scenarios of what could go wrong, to specific and transparent estimates of the actual odds,” Lobell said. “The odds are not very high, but they are significant and a lot bigger than they used to be. The people asking these questions are accustomed to planning for scenarios with much less than a 10 percent chance of happening, so it will be interesting to see whether this study has any effect on how they operate.”

Lobell adds that organizations working toward global food security, and related issues such as conflict prevention, are most interested in the next 20 years because their decisions rarely consider the more distant future.  “As scientists, we might prefer to work on time scales in which the answers are clearer, but we also want to be responsive to the actual concerns and questions that decision makers have.”

Lobell is associate professor of Environmental Earth System Science at Stanford and associate director of the Center on Food Security and the Environment. He is also a senior fellow at the Stanford Woods Institute for the Environment and the Freeman Spogli Institute for International Studies.

The world’s leading economic policymakers are “on the right track” to ensure a global financial upturn, the chief of the International Monetary Fund told a Stanford audience on Tuesday.

But she warned the recovery will be derailed without the creation of more jobs, better education systems and a way to shrink the gap between rich and poor. And she cautioned against the potential pitfalls of untested exchanges and digital currencies such as Bitcoin.

“We are on the right track, but we need to ask – the right track to where? And the right track to what growth?” said Christine Lagarde, the IMF’s managing director. “Will it be solid, sustainable, and balanced – or will it be fragile, erratic, and unbalanced? To answer this question, we need to look at the patterns of economic activity in the years ahead, and especially the role of technology and innovation in driving us forward.”

Lagarde’s visit to Stanford was co-sponsored by the Freeman Spogli Institute for International Studies and the Stanford Institute for Economic Policy Research. In addition to delivering public remarks at FSI’s Bechtel Conference Center, Lagarde met privately with faculty and students during the day.

Just returning from the G-20 summit in Sydney, Lagarde said she is optimistic that the world’s economic leaders are committed to taking the steps that will guard against another large-scale financial collapse. She said the G-20 members agreed to complete a set of financial reforms by the end of this year, a move that will make the “financial sector safer and less likely to cause crisis.”

She said the member countries and their central banks have also agreed to better cooperate and be more transparent in their policymaking.

But she’s worried that unless more sustainable jobs are created, economic disparities will increase. And that, she said, will “harm the pace and sustainability of growth over the long term.”

As technology has helped create a more interconnected world, it is playing an increasing role in the economic landscape. Machines have made our lives easier. Artificial intelligence has led to cars that can drive themselves, robots that can do things in place of humans and smartphones that are more powerful than the first supercomputers.

But so far, there’s been no measure of how new technology has increased productivity.

“We certainly need to keep an eye on this,” she said. “One of the biggest worries is how this technological innovation affects jobs. Put simply: will machines leave workers behind?”

She said technology creates “huge rewards for the extraordinary visionaries at the top, and huge anxieties for workers at the bottom.”

Lagarde said it is up to educators to better prepare the next generation of workers.

“Educational systems are not keeping pace with changing technology and the ever-evolving world of work,” she said. “We need to change what people learn, how people learn, when people learn, and even why people learn. We must go beyond the traditional model of students sitting in classrooms, following instructions and memorizing material. Computers can do that.”

Instead, humans must “outclass computers” in cognitive, interpersonal and sophisticated coding skills, she said.

“Think of creative jobs, caring jobs, jobs that entail great craftsmanship – imagination,” she said. “And given the rate and pace of change, we will need the ability to constantly adapt and change through lifelong learning.”

She called on institutions such as Stanford to play a key role in the process.

“Stanford’s model of education was innovative from the very first day—co-educational, non-denominational, and always practical, focusing on the formation of cultured and useful citizens,” she said. “Stanford was ahead of its time back then. I know that it will continue to be ahead of its time as we venture into the exciting period ahead.”

But that exciting period carries with it uncertainty and risk.

Asked about the role that emerging digital currencies such as Bitcoin could have on the evolving economy, Lagarde was skeptical, calling it a “shaky and wobbly” system.

The currency’s trading website went offline this week, spooking investors and calling into question Bitcoin’s future.

“It’s a glamorous, sexy attractive new system,” she said. “But a monetary system is a public good. It has to be supervised and sufficiently regulated so it is accountable. At this point in time, I think Bitcoin is outside that perimeter of both supervision and regulation.”

Lagarde is the 11th managing director of the IMF, and the first woman to lead the 188-country organization. Since she took over the organization in 2011, she has played a role in the world’s most pressing financial matters, working on solutions to a sluggish global economy and the debt crises in Europe.

The IMF gives both policy advice and financing to countries in difficult economic situations. It also helps developing countries reduce poverty and become more economically stable. 

The organization is now poised to assist Ukraine, which is at risk of running out of money to pay its bills in the midst of a political crisis. The country is struggling to cobble together a temporary government in the wake of President Viktor Yanukovych leaving Kiev and being removed from power.

But until a provisional government is formed, the country cannot technically ask for help. When it does, Lagarde said the IMF will send “technical assistance.”

“We are ready to engage,” she said.

America may have legitimate competitive reasons to worry about the number of computer science and engineering graduates from elite Chinese and Indian universities – the figure dwarfs that of U.S. students with similar degrees.

But a new book by Stanford researchers and others says that the concern that these countries will develop their own centers of high-tech production and innovation and draw research, development and scholarship away from American shores is still premature.

The research, a multidisciplinary look at the growth of higher education in the world's four largest developing economies – Brazil, Russia, India and China (known collectively as the BRICs) – analyzes the quality of institutions, the quantity of people getting degrees and equal access to education.

The book, University Expansion in a Changing Global Economy: Triumph of the BRICS?, is published by Stanford University Press.

"In the past 20 years, university systems in these big countries have just exploded," said Martin Carnoy, a Stanford professor of education and one of the authors. Carnoy is also an affilate of the Center on Democracy, Development, and the Rule of Law at the Freeman Spogli Institute for International Studies.

"So the questions are why did it happen and what are the implications? And specifically, what are the implications for the U.S. if the market is flooded with new scientists and engineers? Are we going to be overwhelmed? What happens to their societies if all the energy is focused on elite institutions," Carnoy said.

The researchers approached their questions with the belief that societies, and governments, can be judged by the way they invest in and organize their public higher education systems.

For example, how well these countries create a labor force that is competitive in the information age depends on the quality of higher education. Whether people have equal chances to succeed relies on having colleges that are accessible to even the poorest students. And how effectively a country expands its university system may determine how successful it is at growing a robust economy and competing with the United States and Europe, the scholars argue.

"If you have economic growth and provide educational opportunities, you're perceived as a legitimate, successful government," Carnoy said. "So our theory was, if you can pull this off, if you can successfully expand your university systems, you are likely a pretty efficient government."

BRIC undergraduate education increased from about 19 million students in 2000 to more than 40 million students in 2010. The largest increase was in China, which went from less than 3 million to almost 12 million bachelor's degree students during that period, the study says.

Financing elite schools

The study found that BRIC countries are pouring money into their elite colleges in an effort to create world-class institutions and have their graduates compete with the United States and Europe.

Researchers say the elite colleges are much better for the focused investment, and the engineers and computer scientists are graduating with similar competency and training as those from developed countries.

But the mass institutions are receiving fewer resources, the study says, and that's where most of the students go. In 2009, 2.1 million of the 2.5 million total bachelor's graduates in China matriculated from mass institutions, not elite ones. In India, it was 2.2 million of 2.3 million.

This widening funding gap between top schools and mass institutions has broad implications, the scholars argue. The gap has the potential to slow economic growth domestically, deepen income inequality and create less social mobility.

Students who go to the mass institutions aren't getting high quality, competitive educational experiences, the study says, and many of the students also get stuck with big bills as funding assistance is directed toward the elite universities.

"What happens, then, is they are doing a good job of educating students at the elite levels, but they are not doing a good job of educating students at the non-elite levels who are also fundamental for the economy," said Prashant Loyalka, a research fellow at FSI and one of the study's authors.

In absolute terms, the sheer numbers of students graduating from elite institutions in computer science and engineering majors in these countries is also high. In China, for example, the total number of computer science and engineering graduates from elite universities is more than the total number of such graduates from the United States.

But sustaining and building innovation hubs requires more than the elite, the researchers said. The engine of these new economies is the rest of the population – those that attend mass institutions.

"In the United States, we have relied on competent second-tier engineers. They are the guts of our system. We need good students in all fields in these second-tier universities because the top-tier universities just don't produce that many graduates. They simply don't," Carnoy said.

He warned that this redistribution of funds away from second-tier institutions is a concern in the United States as well. "To an extent the BRICs have to do it, because they don't have enough resources to go around. But do we have to do it? The answer is probably no. It certainly should be no," Carnoy said.

The research is one of the first empirical and comparative looks at the higher education systems across these countries, and relied on in-country interviews, surveys, data analysis and classroom observation.

Report card

Overall, the researchers found that significant challenges remain as these countries march toward creating universities that can rank alongside those in the United States and Europe.

China, the scholars said, is doing pretty well, but Russia and Brazil are question marks.

"Russia has provided the vast majority of its people with a high level of education, but it has lagged in terms of putting money into research," Loyalka said. "Brazil has a high-level of graduate education and research at its top-tier public institutions, and these institutions are receiving a lot of support. However, the vast majority of students attend private institutions, which are, on average, of dubious quality."

India, Loyalka noted, was surprising. Despite its very good technical universities, he said, "you have a small proportion of Indians going to those, and the mass institutions are of really poor quality."

"The higher education system in India does not appear to be well organized," Loyalka said.

Among other recommendations, the researchers said India should increase its graduate education and, along with Russia, increase spending on research.

The project began in 2007 as an interdisciplinary venture supported by FSI, and incorporated scholars in economics and international comparative education at Stanford Graduate School of Education, FSI and universities in Moscow and Beijing.

Several articles focusing on different aspects of the review also have been published over the past year. The most recent, which appears in the July/August issue of the journal Change, highlights the research on quality and quantity of graduates in engineering and computer science from the four countries.

Besides Carnoy and Loyalka, the scholars involved in the project include Maria Dobryakova, a research associate and the director for portals at the Center for Monitoring Quality Education at the Higher School of Economics in Moscow; Rafiq Dossani, a senior economist at RAND Corp. and former senior research scholar at Stanford's Shorenstein Asia-Pacific Research Center at the Freeman Spogli Institute; Isak Froumin, a mathematician and director of the Institute for Educational Studies at the National Research University Higher School of Economics in Moscow; Katherine Kuhns, who received her PhD in the International and Comparative Education Program at Stanford Graduate School of Education; Jandhyala B. G. Tilak, a professor at the National University of Educational Planning and Administration in New Delhi, India; and Rong Wang, director and professor of the China Institute for Educational Finance Research at Peking University.

“Do we have to accept deforestation to feed the world?”

That was one of the provocative questions that Stanford Woods Institute Senior Fellow and land use expert Eric Lambin posed during a recent presentation of research with far-reaching implications for policymakers, businesses and consumers. Among the findings Lambin discussed with Stanford students and faculty during a Stanford Department of Environmental Earth System Science seminar: There is much less potentially available cropland (PAC) globally than previous estimates have suggested. Perhaps surprisingly, however, we don’t need to clear more land, including forests, to plant hunger-alleviating crops, Lambin said.

Previous PAC estimates by international organizations such as the World Bank have been consistently too high, according to Lambin giving decision-makers “carte blanche” to approve a variety of uses for large tracts of land.

By 2030, the additional land worldwide that will be needed for urban expansion, tree plantations and biofuel crops will equal the additional land that will likely be devoted to food crops, according to Lambin. This rapid transformation of the face of the planet makes it essential to get a handle on realistic PAC estimates. To do so, Lambin took a “bottom-up approach” that incorporated factors such as soil quality, land use restrictions, labor availability and occupation by smallholders. Lambin also considered trade-offs such as the carbon stocks lost and natural habitat destroyed by land conversion.

Lambin’s resulting PAC estimates in regions ranging from Argentina to Russia are, on average, only a third of other generally accepted estimates. Along the way, Lambin discovered some surprises. For example, what initially looked like good news – the fact that some countries have gone from net deforestation to net reforestation in recent years – turned out to be less hopeful. Lambin found that most countries in the developed and developing worlds that have stopped cutting down their forests have increased their imports of timber and wood products, often from tropical countries. This “outsourcing of deforestation” is one of several troubling global land trends.

On the other hand, Lambin pointed out that production of crops essential to alleviating hunger have increased in recent years, but their overall land use has not, due to more efficient and intensive agricultural methods. This net gain contradicts assertions that more land, including forests, needs to be cleared for farming in order to alleviate hunger, he said.

The real culprit for such land conversion, according to Lambin, is growing adoption of a Western diet heavy with meat, sugar and vegetable oils. Deforestation for agriculture is often driven by multinational companies that cultivate in tropical regions to export fatty and oily food products to urban markets in rich countries and emerging economies. These companies control a majority of global food supply chains and, in turn, local land use decisions. “Globalization has reshaped land governance,” Lambin said.

Globalization is not a bogeyman, though. In fact, Lambin said, it can be an engine for progress on these issues by allowing for new forms of market-based governance that effectively promote sustainable land use. Market mechanisms such as eco-certification labels and nongovernmental campaigns can promote and incentivize responsible land use, he noted, pointing to coffee farmers he studied with School of Earth Sciences Research Associate Ximena Rueda. The farmers increased tree cover on their plantations with the extra profit they reaped from eco-certified beans.

Climate change is already affecting crop production around the world through rising temperatures, changes in rainfall patterns and increasing CO2 in the atmosphere. A new Stanford study published June 14 in Environmental Research Letters examines extreme heat effects on crops during the flowering period and finds the world's staple crops are increasingly at risk.

We are beginning to see exposure to reproductive extreme heat for wheat in Central & South Asia and for rice in South Asia. Maize (corn) harvested area exposed to extreme heat is projected to grow from 15% in the 2000s to 44% by 2050. By 2050, all crops will see increased exposure, especially in tropical areas. For rice, the primary growing areas in South, Southeast and East Asia will become increasingly risky, whereas for wheat, Russia, Central Asia, and the Middle East will continue to be problematic.

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.

Policy brief: Climate trend and global crop production since 1980

Global warming is likely already taking a toll on world wheat and corn production, according to a new study led by Stanford University researchers. But the United States, Canada and northern Mexico have largely escaped the trend.

"It appears as if farmers in North America got a pass on the first round of global warming," said David Lobell, an assistant professor of environmental Earth system science and center fellow at the Program on Food Security and the Environment at Stanford University. "That was surprising, given how fast we see weather has been changing in agricultural areas around the world as a whole."

Lobell and his colleagues examined temperature and precipitation records since 1980 for major crop-growing countries in the places and times of year when crops are grown. They then used crop models to estimate what worldwide crop yields would have been had temperature and precipitation had typical fluctuations around 1980 levels.

The researchers found that global wheat production was 5.5 percent lower than it would have been had the climate remained stable, and global corn production was lower by almost 4 percent. Global rice and soybean production were not significantly affected.

The United States, which is the world's largest producer of soybeans and corn, accounting for roughly 40 percent of global production, experienced a very slight cooling trend and no significant production impacts.

Outside of North America, most major producing countries were found to have experienced some decline in wheat and corn (or maize) yields related to the rise in global temperature. "Yields in most countries are still going up, but not as fast as we estimate they would be without climate trends," Lobell said.

Lobell is the lead author of the paper, Climate Trends and Global Crop Production Since 1980, published May 5 online in Science Express.

Russia, India and France suffered the greatest drops in wheat production relative to what might have been with no global warming. The largest comparative losses in corn production were seen in China and Brazil.

Total worldwide relative losses of the two crops equal the annual production of corn in Mexico and wheat in France. Together, the four crops in the study constitute approximately 75 percent of the calories that humans worldwide consume, directly or indirectly through livestock, according to research cited in the study.

"Given the relatively small temperature trends in the U.S. Corn Belt, it shouldn't be surprising if complacency or even skepticism about global warming has set in, but this study suggests that would be misguided," Lobell said.

Since 1950, the average global temperature has increased at a rate of roughly 0.13 degrees Celsius per decade. But over the next two to three decades average global temperature is expected to rise approximately 50 percent faster than that, according to the report of the Intergovernmental Panel on Climate Change. With that rate of temperature change, it is unlikely that the crop-growing regions of the United States will continue to escape the rising temperatures, Lobell said.

"The climate science is still unclear about why summers in the Corn Belt haven't been warming. But most explanations suggest that warming in the future is just as likely there as elsewhere in the world," Lobell said.

"In other words, farmers in the Corn Belt seem to have been lucky so far."

This is the first study to come up with a global estimate for the past 30 years of what has been happening, Lobell said.

To develop their estimates, the researchers used publicly available global data sets from the United Nations Food and Agriculture Organization and from the University of Delaware, University of Wisconsin, and McGill University.

The researchers also estimated the economic effects of the changes in crop yield using models of commodity markets.

"We found that since 1980, the effects of climate change on crop yields have caused an increase of approximately 20 percent in global market prices," said Wolfram Schlenker, an economist at Columbia University and a coauthor of the paper in Science.

He said if the beneficial effects of higher carbon dioxide levels on crop growth are factored into the calculation, the increase drops down to 5 percent.

"Five percent sounds small until you realize that at current prices world production of these four crops are together worth nearly $1 trillion per year," Schlenker said. "So a price increase of 5 percent implies roughly $50 billion per year more spent on food."

Rising commodity prices have so far benefited American farmers, Lobell and Schlenker said, because they haven't suffered the relative declines in crop yield that the rest of the world has been experiencing.

"It will be interesting to see what happens over the next decade in North America," Lobell said. "But to me the key message is not necessarily the specifics of each country. I think the real take-home message is that climate change is not just about the future, but that it is affecting agriculture now. Accordingly, efforts to adapt agriculture such as by developing more heat- and drought-tolerant crops will have big payoffs, even today. "

Justin Costa-Roberts, an undergraduate student at Stanford, is also a coauthor of the Science paper. David Lobell is a researcher in Stanford's Program on Food Security and the Environment, a joint program of Stanford's Woods Institute for the Environment and Freeman Spogli Institute for International Studies. Schlenker is an assistant professor at the School of International and Public Affairs and at the Department of Economics at Columbia.

The work was supported by a grant from the Rockefeller Foundation.

February 10th marked the launch of the Program on Food Security and the Environment's Global Food Policy and Food Security Symposium Series. Setting the stage for the two-year series were Jeff Raikes, CEO of the Bill & Melinda Gates Foundation, and Greg Page, CEO and Chairman of Cargill Inc. As CEOs from the largest foundation and the largest agricultural firm in the world they provided important perspectives on global food security in these particularly volatile times. Full video and clips of the event are now available - Improving Food Security in the 21st Century: What are the Roles for Firms and Foundations.

Jeff Raikes: A Perspective from the Bill & Melinda Gates Foundation

Catalytic philanthropy

The Gates Foundation, through its Agricultural Development Initiative, has been a leader in addressing global food security issues. The Foundation allocates 25% of its resources to global development and to addressing the needs of the 1 billion people who live in extreme poverty ($1/day). 70-75% of those people live in rural areas and are dependent on subsistence agriculture for their livelihoods.

The Gates Foundation is driven by the principle: how can it invest its resources in ways that can leverage performance and address market failures? Its approach embodies a novel concept driven by both private sector motives and public responsibilities. Raikes describes this as catalytic philanthropy.

"The Foundation identifies where its investments can create an innovation, a new intervention that can really raise the quality of lives for people," said Raikes. "If successful, it can be scaled up and sustained by the private sector if we can show that there is a profit opportunity or the public sector if we can show that this is a better way to improve the overall quality of society through investment in public dollars."

In the realm of agriculture, allocating resources across the agricultural value chain has proven to be the most effective approach. As an example of this strategy, Raikes talked about a farmer-owned, Gates-supported dairy chilling plant in Kenya. The cooling facility provided the storage necessary to provide a predictable price at which to sell farmers' milk. This price knowledge and market access gave farmers the confidence to invest in better technology and better dairy cattle. The plant also provided artificial insemination services and extension services to teach farmers how to get greater amounts of milk from the cattle.

"I love the concept. I also love the numbers," said Raikes. "In just two or three years there were now 3,000 farmers in a 25 kilometer radius that were able to access this dairy chilling plant and able to sell their milk."

In addition to improving incomes, Raikes remarked that very consistently what he hears is when farmers are able to improve their incomes the first thing they do with the money is invest in the education of their children.

Upcoming challenges to food security

During the next 40 years or so, global food production must double to accommodate a growing and richer population. Climate change and water scarcity contribute to this challenge. The places that will suffer the most severe weather are also the places where the poorest farmers live. 95% of sub-Saharan agriculture is rain fed with very little irrigation.

"If we are going to be able to feed the world we are going to have to figure out how to achieve more crop per drop," cautioned Raikes. "This includes trying to breed crop varieties that will better withstand water shortages. Early results show that you can get as much as a 20% increase in yield or more under stressed conditions when you have varieties that are bred for that need."

These challenges are compounded by the current economic crisis that is putting pressure on budgets in both donor and developing countries. In 2009, the G20 committed 22 billion dollars to agricultural development in recognition of the importance of agricultural development to food security. However, of the 22 billion promised, 224 million dollars went to five countries in the first round of grants in June. By November, when 21 additional countries submitted their proposals, just 97 million dollars were available to be dispersed and 17 countries were turned away empty handed.

High- and low-tech solutions

In an effort to alleviate some of this deficit, the Gates Foundation has committed 300 million dollars in six grants that span the value chain. These include investments in science and technology, farm management practices, farmer productivity, and market access as well as the data and policy environment to support the Foundation's work. The grants are intended to support about 5 ½ million farm families in sub-Saharan Africa and South Asia.

"We believe innovative solutions can come from both high-tech and low-tech," said Raikes. "On the high-tech end, submergent genes are allowing rice crops to survive periods of flooding up to 15 days. In areas of rice farming prone to flooding, this can save entire crops traditionally wiped out by such weather disasters."

The sub1gene seeds are now being used by 400,000 farmers and are on track to be used by 20 million rice farmers by 2017. On the low-tech end, the Gates Foundation is providing $2 triple layer bags to farmers to reduce crop loss from pests; an affordable solution that has increased average income per farmer by $150/year.

"We primarily support conventional breeding, but we also support biotechnology breeding. In some cases we think that breeders in Africa and South Asia will want to take advantage of the modern tools we use here in our country to provide better choices for their farmers," explained Raikes.

Reasons for optimism

After years of diminished support, US Agricultural Development assistance to sub-Saharan Africa has gone from about 650 million in 2005 to about 1.5 billion in 2009. In developing countries, the Comprehensive Agricultural Development Program (CADP) in Africa has challenged countries to dedicate 10% of their national budgets to agriculture with the goal of improving annual agricultural growth by 6%. 20 countries have signed on to the CADP compacts, and 10 countries are exceeding the 6% growth target. Finally, since 1990, 1.3 billion people worldwide have lifted themselves out of poverty primarily through improvements in agricultural productivity.

Raikes pointed to Ghana as a success story. Since 1990, casaba production, an important staple food for poor smallholder farmers, has increased fivefold. Tomato production increased six fold. The cocoa sector has been revived and hunger has been cut by 75%.

"The key to success in Ghana was a combination of getting the right developing country policy with the right macroeconomic reform, the right institutional reform, smart public investment, and an overall good policy environment," said Raikes.

Supporting good policy is an important part of the Foundation's food security strategy, and was a strong motivation behind its funding of FSE's Global Food Policy and Food Security Symposium series.

"We see this symposium series as an opportunity to gather policy leaders who will bring new ideas of what will be effective policy approaches and effective economic environments in the countries we care a lot about, in particular sub-Saharan Africa and South Asia," said Raikes.

Raikes concluded his remarks by reminding everyone that the key to improving food security globally is making sure women, who make up at least 70% of the farm labor population, are included in the equation.

Greg Page: Balancing the race to caloric sufficiency with rural sociology

As the largest global agricultural firm, Cargill has an influential role to play in the world of food and agriculture. Cargill is a major supplier of food and crops and a provider of farmer services, inputs, and market access.

Together with the Gates Foundation, Cargill has reached out and trained 200,000 cocoa farmers in the Ivory Coast, Ghana, and Cameroon. One tribe and one small village at a time the company has helped improve food safety, quality maintenance, and storage; benefiting the farmers, Cargill, and customers further down the supply chain. Cargill has also assisted, through financing and product purchasing, 265,000 farmers in Benin, Burkina Faso, the Ivory Coast, Malawi, Uganda, Zambia, and Zimbabwe.

Can the world feed itself?

A billion people lack sufficient caloric intake on a daily basis. In sub-Saharan Africa, 38% of all children are chronically malnourished, largely the result of inadequate agricultural productivity. While nine of the ten countries that have the highest prevalence of malnourishment are in sub-Saharan Africa, the two countries with the largest absolute number of malnourished people are India and China.

"This points to the difficulty of this problem," said Page. "India exports corn and soybean protein and China has 2.5 trillion dollars of hard currency reserves. These issues aren't necessarily of ability to feed people, but a willingness and commitment to do so."

Can the world feed itself? Yes, said Page.

When you break down the number of calories needed per malnourished person per day and convert that to tons of whole grains required to extinguish that hunger you get 30 million tons; 1/6 the amount of grain we converted to fuel globally last year. In the U.S. alone, 40% of our corn goes to ethanol.

"It isn't an issue of caloric famine-it is an issue of economic famine," stated Page. "In other words, this is not a food supply problem, but rather the lack of purchasing power to pay for a diet. An adequate price must be assured to reward the farmer for his efforts and to provide enough money that she can do it again the following year."

Rural sociology premium

What we face is the need to keep smallholders on the farm-despite the fact that they may not be the low-cost producer of foodstuffs-in order to avoid a rural population migration that would be unsustainable. As a result, the challenge the world faces is who is going to pay that rural sociology premium? If it costs more to raise crops on small farms is that burden going to be borne by the urban poor or is there going to be an alternative funding mechanism that allows smallholders to succeed?

What is the survival price for a smallholder farmer? Page explained that if you wanted a family of four on a farm in sub-Saharan Africa to receive an income commensurate with the average per capita income of the urban population, you would come up with a price near $400 a ton.

"To put this in context, the highest price for maize that has ever been reached here in the United States is about $275 a ton," said Page. "This rural sociology premium to sustain smallholders is not an insignificant amount of money. How do we achieve fairness between the revenue received by the rural smallholder and the price borne by the urban consumer?"

State of disequilibrium - complacency to crisis

Today we are experiencing incredible price volatility where commodity prices are in a continuous state of disequilibrium. Very small changes in production have outsized impacts on price. This is in contrast to the last two and a half decades when the world operated with fairly robust stocks due to crop subsidies in the United States and Western Europe.

"This period of subsidization was when the western world probably did more harm to sub-Saharan Africa and South Asia than any other period in history," said Page. "We refused to allow price to signal to western farmers to produce less. As a result, the world price of grains fell far below the ability of any smallholder to compete. We then shipped those surpluses to developing countries, which then failed to invest in their agriculture for decades."

Today we are lurching from complacency to crisis. The ability of information and market speculation to be transmitted rapidly is affecting purchasing decisions of thousands to millions of consumers. Rising fuel prices, export restrictions, increasing demand for crops for biofuels, and unpredictable weather have all contributed to higher prices. Some of the drivers of price, however, are good things, such as the increase in per capita income and the capacity of more people to have a more dense and nutritious diet.

"Interestingly, the upside of the ethanol and biofuels program is that it brought prices back to a sufficiency that reinvigorated investment in agriculture," noted Page. "On one level I think a very good argument could be made that the biofuels program brought the world further from famine than it ever had been because of the price."

Critical food security factors

Page concluded by summarizing the elements that Cargill believes are critically important to increase food security. The first is the ability to understand the tradeoffs between a fast path to caloric sufficiency and the needs of rural sociology. Second, that crops be grown in the right soil, with the right technology, and relying on free trade so we can harvest competitive advantage to its fullest.

Another critical factor is rural property rights. Smallholders must have the ability to own the land, have access to it, and transfer it to future generations if you want a farmer to reinvest in his farm, said Page.

"Smallholders in developing countries need some degree of revenue certainty and access to a reliable market if we expect them to do what their countries really need them to do, which is raise productivity," explained Page. "Today they are often forced to sell at harvest, often below the cost of production, and lack the storage capabilities and capital to provide crops sufficiently and continuously."

Open, trust-based markets also play a key role in ensuring food security. Governments need to support trade. When Russia, Ukraine, and Argentina turned to embargos as a way to protect domestic food prices open markets were jeopardized and price volatility increased. Finally, there are very important roles for the world's governments in the creation of infrastructure that is vital to provide access to markets.

"I believe fully and completely in the world's capacity to harvest photosynthesis to feed every single person and to do it at prices that can be borne by all," concluded Page.

With 2011 already off to such a wet start in many parts of the world, concerns of what flooding will do to food prices and availability in the coming months are starting to creep into the news. In Sri Lanka, flooding has devastated rice crops, and in North Dakota, heavy rain and snow is already threatening the spring wheat crop. And all this after last summer's Russian drought and heat wave helped drive global wheat prices higher.

But while farmers have always had to contend with the vagaries of the weather, a question of increasing importance is how agriculture will be affected by the climate changes projected to occur over the next century. Many scientists are studying which regions of the world may be impacted the most by increasing temperatures and changing precipitation regimes, and what is bound to happen to the supplies of the world's biggest cash crops, like wheat, corn, rice and soybeans.

A new report, The Food Gap, was released last week from the Universal Ecological Fund, and it has muddied the waters even further. The report reviews how global climate change will affect the fate of crop yields and food prices in 2020. Unfortunately, the report actually misinterpreted the connection between atmospheric concentrations of greenhouse gases like carbon dioxide (CO2) and expected global temperature increases - despite the fact that recent reports from the U.N. Intergovernmental Panel on Climate Change and the National Academy of Sciences clearly identify the most current peer-reviewed understanding of this. The food study suggests that within 9 years, average global temperatures will be an average of 2.4°C warmer than during preindustrial times - or almost 1.5°C warmer than it was just last year.

This exceptionally high temperature projection is completely baseless, as NASA climate modeler Gavin Schmidt explained on the RealClimate blog - it's more likely that the planet will experience this kind of temperature change over 100 years, not merely one decade. Nevertheless, a number of news outlets published stories on the report's projections of how this dramatic climate change could impact the global food supply by 2020. Some publications posted corrections to their own stories, but I thought it would be helpful to take a step back and examine climate change and food security in 2020 and beyond. I spoke with Stanford University's David Lobell, who studies how climate change affects crop yields and food prices. He helped clarify what the current research says about climate change and food security.
