The Freeman Spogli Institute for International Studies (FSI) at Stanford University is pleased to announce that former U.S. Ambassador and World Food Programme (WFP) Executive Director Ertharin Cousin will return for a second year at Stanford. Cousin will serve as the Frank E. and Arthur W. Payne Distinguished Lecturer at FSI and Distinguished Fellow at the Center on Food Security and the Environment and the Center on Democracy, Development and the Rule of Law.

Cousin brings over 30 years of experience addressing hunger and food security strategies on both a national and international scale. As U.S. Ambassador to the United Nations Agencies for Food and Agriculture, she focused on advocating for longer-term solutions to food insecurity and hunger, and at WFP she addressed the challenges of food insecurity in conflict situations.

We caught up with Cousin to ask about her plans for this upcoming school year.

If you had to pick out one thing that most concerns you in the realm of food security, what would it be?

Water access, particularly in terms of smallholder farmer centered irrigation and water management. The development community spent much of the past 10 years working to improve farmers’ access to the right seeds and tools – recognizing the need to increase the quality and quantity of their yields. A significant amount of work has also been performed related to improving private sector investment and to the development of markets including access for smallholder farmers.

Today there are approximately 500 million smallholder farmers in the world. The most vulnerable live and work in places where climate change creates ever more erratic rainy seasons. Particularly, in sub-Saharan Africa where 97 percent of all agriculture remains rain-fed. Too often the short rains don’t come, and the long rains produce insufficient precipitation. Inadequate policy management of diminishing water resources represents a significant problem which we must overcome to make agriculture productive and sustainable for the most vulnerable.

And what work have you been doing to address this issue?

I am working on a number of policy research and development projects. For example, I am co-chairing the Chicago Council on Global Affairs (CCGA) 2019 Global Food Security Symposium’s report exploring the linkages between water management and food security particularly as it relates to nutrition security. The report release will occur March 21, 2019 at the CCGA Food Security Symposium.

Over the past year, you also have been working on a project to encourage the private sector to create sustainable food systems. How is that going?

My work identifying and addressing policy-related challenges impacting private sector partnership and investment in global food system solutions continues. Globally, there is growing recognition that we cannot fix the broken global food system if we do not work to create collaborative efforts between public and private sector, academia, government, non-profits and larger society.

Governments, particularly those in developing countries, often lack both the financial resources and technical capacity required to perform the work and the investment necessary to fix our global food system. Governments and civil society must include private sector as an equal and desired partner. Government policies at the global, state and local level should support and encourage private sector participation.

Using my role here at Stanford as a platform to broker research and information both to private sector as well as to government, has proven quite successful over the past year. In very simple terms, helping global governments understand generating profit does not make the private sector a bad partner.

What successes have you had so far?

I was just in Amsterdam to meet with Royal DSM, a nutrition products manufacturer, with whom I developed a relationship during my tenure at the World Food Programme. In Kigali in Rwanda, DSM and several other partners - including the national government - have developed and are now operating the Africa Improved Foods company, the first European-type baby food manufacturing facility. European-type baby food differs from American products in terms of their lack of sweeteners and conservative use of food preservatives, lack of detectable pesticides (due to farming practices), and their stage-approach: they produce different products for the various stages of baby growth (from birth to 4 years) that cater to the specific nutritional needs of the child. Several farming cooperatives, representing approximately 10,000 Rwandan small farmers, form the sole supply chain for this baby food factory.

WFP serves as a catalyst market for the plant, purchasing the supplemental nutrition product distributed through the region’s targeted nutrition improvement program. The sustainability of the factory is directly related to the partners ability to grow (in addition to WFP) an institutional and a commercial consumer market for this easy-access, nutrient-rich food that is specifically made for children. I am assisting DSM and the government of Rwanda by helping to identify the policy changes required to ensure the sustainability of this public-private partnership. As a proof-of-concept, the success of AIF, will result in new public-private development opportunities. This initiative offers a case study demonstrating how collaboration between the private sector and government actually provides positive benefits for both farmers and nutritious food for consumers.

Why Stanford? How has being here helped your work?

Serving here at Stanford represents my first opportunity to work in academia on a full-time basis. I am a lawyer with over 30 years of experience of working on complicated domestic and global humanitarian and development issues; particularly, hunger related issues. I believe my experience adds value to any academic community. But in many institutions, the value of experience is not readily embraced, particularly because I don't have a PhD and haven’t spent 20 years in a classroom. At Stanford, I discovered collegial faculty, brilliant students and a recognition as well as a respect for my experience-based knowledge. I have received a welcoming response across the campus, collaborating with the law school, colleagues in the medical school, earth system sciences and the business school. The only limit to my participation and partnership with the amazing academic leaders here at Stanford has been time. I am quite looking forward to the opportunities for engagement provided by my additional time on campus.

The Center on Food Security and the Environment (FSE) addresses critical global issues of hunger, poverty and environmental degradation and is a joint effort of the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment.

The Center on Democracy, Development and the Rule of Law is an interdisciplinary center for research on development in all of its dimensions:  political, economic, social and legal, and the ways in which these different dimensions interact with one another.

"Right now, the world is closer than ever before to ending global hunger, undernutrition, and extreme poverty, but significant challenges and opportunities remain, including urbanization, gender inequality, instability and conflict, the effects of a changing climate, and environmental degradation. Despite our collective progress in global food security and nutrition over recent years, a projected 702 million people still live in extreme poverty, nearly 800 million people around the world are chronically undernourished, and 159 million children under five are stunted. Food security is not just an economic and humanitarian issue; it is also a matter of security, as growing concentrations of poverty and hunger leave countries and communities vulnerable to increased instability, conflict, and violence."

New research finds that without climate change mitigation, even wealthy countries will see an economic downturn by 2100.

When thousands of scientists, economists and policymakers meet in Paris this December to negotiate an international climate treaty, one question will dominate conversations: what is the climate worth?

A new study published in the journal Nature shows that the global economy will take a harder hit from rising temperatures than previously thought, with incomes falling in most countries by the year 2100 if climate change continues unchecked. Rich countries may experience a brief economic uptick, but growth will drop off sharply after temperatures pass a critical heat threshold.

The study, co-led by Marshall Burke, a professor of Earth system science at Stanford's School of Earth, Energy & Environmental Sciences, provides a clear picture of how climate change will shape the global economy, which has been a critical missing piece for the international climate community leading up to the Paris talks. Understanding how much future climate change will cost in terms of global economic losses will help policymakers at the meetings decide how much to invest in emissions reductions today.

The work was co-authored by two researchers from the University of California, Berkeley: co-lead author Solomon Hsiang, the Chancellor's Associate Professor of Public Policy, and Edward Miguel, Oxfam Professor in Environmental and Resource Economics. 
 

Heat threshold

"The data tell us that there are particular temperatures where we humans are really good at producing stuff," said Burke, who is also Center Fellow at the Freeman Spogli Institute for International Studies and fellow, by courtesy, at the Stanford Woods Institute for the Environment. "In countries that are normally quite cold - mostly wealthy northern countries - higher temperatures are associated with faster economic growth, but only to a point. After that point, growth declines rapidly.

That point, it turns out, is an annual average temperature of about 55 degrees Fahrenheit.

As average temperatures move past that mark, wealthy countries will start to see a drop-off in economic output. Poorer countries, mostly in the tropics, will suffer even steeper losses because they are already past the temperature threshold. This has the potential to widen the global inequality gap, said Burke. 
 

A new approach

Looking at existing research, the team found a puzzling mismatch between micro-level studies, which show negative impacts of hot temperatures on output in specific sectors such as agriculture, and macro-level studies, which at least in rich countries show limited impacts on economic output.

"Many very careful studies show clearly that high temperatures are bad for things like agriculture and labor productivity, even in rich countries," Burke said. "While these relationships showed up again and again in the micro data – for example when looking at agricultural fields or manufacturing plants – they were not showing up in the existing macro-level studies, and we wanted to understand why."

The researchers suspected the problem was with the analysis, not the data, so they took a new approach.

Analyzing records from 166 countries over a 50-year period from 1960 to 2010, they compared each country's economic output in years of normal temperatures to that of unusually warm or unusually cool years. The data revealed a hill-shaped relationship between economic output and temperature, with output rising until the 55 F threshold and then falling faster and faster at higher temperatures. “Our macro-level results lined up nicely with the micro-level studies,” Hsiang said.

Higher temperatures, lower growth

The team then sought to understand what this historical pattern might mean for the future global economy as temperatures continue to warm. 

“Many other researchers have projected economic impacts under future climate change,” Hsiang said. “But we feel our results improve our ability to anticipate how societies in coming decades might respond to warming temperatures.”

Projecting future changes in economic output under climate change was challenging.

“Even without climate change, there are a lot of possible ways in which the future economy might evolve,” Burke said. “We start with a few different baseline scenarios and then we bring in our historical understanding of the relationship between temperature and economic output to better understand how these economic trajectories might change with warming temperatures."

The researchers’ findings were stark. 

In a scenario of unmitigated climate change, the team’s model shows that by 2100 the per-capita incomes of 77 percent of countries in the world would fall relative to current levels. By the team’s main estimate, global incomes could decline 23 percent by 2100, relative to a world without climate change. Other estimates are twice as high. The likelihood of global economic losses larger than 20 percent of current income is at least 40 percent, and much higher in some scenarios. 

These estimates are substantially larger than existing models indicate, a difference the research team attributes to their updated and data-driven understanding of how countries have historically responded to temperature increases.

Rich countries not immune

A common assumption among researchers has been that wealth and technology protect rich countries from the economic impacts of climate change, because they use these resources to adapt to higher temperatures.

"Under this hypothesis, the impacts of future warming should lessen over time as more countries become richer," Burke said. "But we find limited evidence that this is the case."

Burke's team found that, historically, rich countries did not appear to respond any differently to temperature change than poor countries. 

“The data definitely don’t provide strong evidence that rich countries are immune from the effects of hot temperatures,” said Hsiang.  “Many rich countries just happen to have cooler average temperatures to start with, meaning that future warming will overall be less harmful than in poorer, hotter countries.”

Paris climate talks

From Nov. 30 to Dec. 11, France will host the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21/CMP11).

More than 40,000 delegates from national governments, private companies and civil society will meet in Paris to hash out an international agreement aimed at keeping global emissions low enough to prevent warming of more than two degrees Celsius.

On the table are three key issues: climate adaptation, mitigation and financing.

"We don't want to rule out that we could see unprecedented adaptation to hotter temperatures in the future, and we certainly hope we do see it," Burke said. "The historical evidence, though, suggests that this is not something we should count on."

The team says that mitigation, and how to pay for it, should be at the forefront of discussions in Paris.

"Our research is important for COP21 because it suggest that these economic damages could be much larger than current estimates indicate," said Burke. "What that means for policy is that we should be willing to spend a lot more on mitigation than we would otherwise. The benefits of action on mitigation are much greater than we thought, because the costs of inaction are much greater than we thought."

Note for reporters: The research team has created a website about their research results and methodology, including an interactive map showing country-by-country GDP projections through 2100 under a scenario of unmitigated climate change.

For 14 years, Mariano-Florentino Cuéllar has been a tireless Stanford professor who has strengthened the fabric of university’s interdisciplinary nature. Joining the faculty at Stanford Law School in 2001, Cuéllar soon found a second home for himself at the Freeman Spogli for International Studies. He held various leadership roles throughout the institute for several years – including serving as co-director of the Center for International Security and Cooperation. He took the helm of FSI as the institute’s director in 2013, and oversaw a tremendous expansion of faculty, research activity and student engagement. 

An expert in administrative law, criminal law, international law, and executive power and legislation, Cuéllar is now taking on a new role. He leaves Stanford this month to serve as justice of the California Supreme Court and will be succeeded at FSI by Michael McFaul on Jan. 5.

 As the academic quarter comes to a close, Cuéllar took some time to discuss his achievements at FSI and the institute’s role on campus. And his 2014 Annual Letter and Report can be read here.

You’ve had an active 20 months as FSI’s director. But what do you feel are your major accomplishments? 

We started with a superb faculty and made it even stronger. We hired six new faculty members in areas ranging from health and drug policy to nuclear security to governance. We also strengthened our capacity to generate rigorous research on key global issues, including nuclear security, global poverty, cybersecurity, and health policy. Second, we developed our focus on teaching and education. Our new International Policy Implementation Lab brings faculty and students together to work on applied projects, like reducing air pollution in Bangladesh, and improving opportunities for rural schoolchildren in China.  We renewed FSI's focus on the Ford Dorsey Program in International Policy Studies, adding faculty and fellowships, and launched a new Stanford Global Student Fellows program to give Stanford students global experiences through research opportunities.   Third, we bolstered FSI's core infrastructure to support research and education, by improving the Institute's financial position and moving forward with plans to enhance the Encina complex that houses FSI.

Finally, we forged strong partnerships with critical allies across campus. The Graduate School of Business is our partner on a campus-wide Global Development and Poverty Initiative supporting new research to mitigate global poverty.  We've also worked with the Law School and the School of Engineering to help launch the new Stanford Cyber Initiative with $15 million in funding from the Hewlett Foundation. We are engaging more faculty with new health policy working groups launched with the School of Medicine and an international and comparative education venture with the Graduate School of Education. 

Those partnerships speak very strongly to the interdisciplinary nature of Stanford and FSI. How do these relationships reflect FSI's goals?

The genius of Stanford has been its investment in interdisciplinary institutions. FSI is one of the largest. We should be judged not only by what we do within our four walls, but by what activity we catalyze and support across campus. With the business school, we've launched the initiative to support research on global poverty across the university. This is a part of the SEED initiative of the business school and it is very complementary to our priorities on researching and understanding global poverty and how to alleviate. It's brought together researchers from the business school, from FSI, from the medical school, and from the economics department.  

Another example would be our health policy working groups with the School of Medicine. Here, we're leveraging FSI’s Center for Health Policy, which is a great joint venture and allows us to convene people who are interested in the implementation of healthcare reforms and compare the perspective and on why lifesaving interventions are not implemented in developing countries and how we can better manage biosecurity risks. These working groups are a forum for people to understand each other's research agendas, to collaborate on seeking funding and to engage students. 

I could tell a similar story about our Mexico Initiative.  We organize these groups so that they cut across generations of scholars so that they engage people who are experienced researchers but also new fellows, who are developing their own agenda for their careers. Sometimes it takes resources, sometimes it takes the engagement of people, but often what we've found at FSI is that by working together with some of our partners across the university, we have a more lasting impact.

Looking at a growing spectrum of global challenges, where would you like to see FSI increase its attention? 

FSI's faculty, students, staff, and space represent a unique resource to engage Stanford in taking on challenges like global hunger, infectious disease, forced migration, and weak institutions.  The  key breakthrough for FSI has been growing from its roots in international relations, geopolitics, and security to focusing on shared global challenges, of which four are at the core of our work: security, governance, international development, and  health. 

These issues cross borders. They are not the concern of any one country. 

Geopolitics remain important to the institute, and some critical and important work is going on at the Center for International Security and Cooperation to help us manage the threat of nuclear proliferation, for example. But even nuclear proliferation is an example of how the transnational issues cut across the international divide. Norms about law, the capacity of transnational criminal networks, smuggling rings, the use of information technology, cybersecurity threats – all of these factors can affect even a traditional geopolitical issue like nuclear proliferation. 

So I can see a research and education agenda focused on evolving transnational pressures that will affect humanity in years to come. How a child fares when she is growing up in Africa will depend at least as much on these shared global challenges involving hunger and poverty, health, security, the role of information technology and humanity as they will on traditional relations between governments, for instance. 

What are some concrete achievements that demonstrate how FSI has helped create an environment for policy decisions to be better understood and implemented?

We forged a productive collaboration with the U.N. High Commissioner for Refugees through a project on refugee settlements that convened architects, Stanford researchers, students and experienced humanitarian responders to improve the design of settlements that house refugees and are supposed to meet their human needs. That is now an ongoing effort at the UN Refugee Agency, which has also benefited from collaboration with us on data visualization and internship for Stanford students. 

Our faculty and fellows continue the Institute's longstanding research to improve security and educate policymakers. We sometimes play a role in Track II diplomacy on sensitive issues involving global security – including in South Asia and Northeast Asia.  Together with Hoover, We convened a first-ever cyber bootcamp to help legislative staff understand the Internet and its vulnerabilities. We have researchers who are in regular contact with policymakers working on understanding how governance failures can affect the world's ability to meet pressing health challenges, including infectious diseases, such as Ebola.

On issues of economic policy and development, our faculty convened a summit of Japanese prefectural officials work with the private sector to understand strategies to develop the Japanese economy.  

And we continued educating the next generation of leaders on global issues through the Draper Hills summer fellows program and our honors programs in security and in democracy and the rule of law. 

How do you see FSI’s role as one of Stanford’s independent laboratories?

It's important to recognize that FSI's growth comes at particularly interesting time in the history of higher education – where universities are under pressure, where the question of how best to advance human knowledge is a very hotly debated question, where universities are diverging from each other in some ways and where we all have to ask ourselves how best to be faithful to our mission but to innovate. And in that respect, FSI is a laboratory. It is an experimental venture that can help us to understand how a university like Stanford can organize itself to advance the mission of many units, that's the partnership point, but to do so in a somewhat different way with a deep engagement to practicality and to the current challenges facing the world without abandoning a similarly deep commitment to theory, empirical investigation, and rigorous scholarship.

What have you learned from your time at Stanford and as director of FSI that will inform and influence how you approach your role on the state’s highest court?

Universities play an essential role in human wellbeing because they help us advance knowledge and prepare leaders for a difficult world. To do this, universities need to be islands of integrity, they need to be engaged enough with the outside world to understand it but removed enough from it to keep to the special rules that are necessary to advance the university's mission. 

Some of these challenges are also reflected in the role of courts. They also need to be islands of integrity in a tumultuous world, and they require fidelity to high standards to protect the rights of the public and to implement laws fairly and equally.  

This takes constant vigilance, commitment to principle, and a practical understanding of how the world works. It takes a combination of humility and determination. It requires listening carefully, it requires being decisive and it requires understanding that when it's part of a journey that allows for discovery but also requires deep understanding of the past.

Michael McFaul, a Stanford political scientist and former U.S. ambassador to Russia, has been selected as the next director of the university’s Freeman Spogli Institute for International Studies.

The announcement was made Wednesday by Stanford Provost John Etchemendy and Ann Arvin, the university’s vice provost and dean of research. McFaul will succeed Mariano-Florentino Cuéllar, who was nominated in July as an associate justice of the California Supreme Court and elected Tuesday.

McFaul takes the helm of FSI in January.

"Stanford has long been a home for scholars who connect academia to policy and public service, and Professor McFaul is the embodiment of that model," Etchemendy said. "We are grateful for Mike's service and confident he will be a strong leader for FSI."

Arvin said McFaul is a strong fit for the position.

“Professor McFaul’s background as an outstanding scholar and his service as an influential ambassador give him a vital perspective to lead FSI, which is Stanford’s hub for studying and understanding international policy issues,” she said. “His scholarship, experience and energy will keep FSI and Stanford at the forefront of international studies as well as some of the most pressing global policy debates."

McFaul has been a faculty member in the department of political science at Stanford since 1994.  He joined the Obama administration in January 2009, serving for three years as Special Assistant to the President and Senior Director for Russian and Eurasian Affairs at the National Security Council at the White House. He then served as U.S. Ambassador to the Russian Federation from 2012 to 2014.

McFaul already has a deep affiliation with FSI. Before joining the government, he served as FSI deputy director from 2006 to 2009.  He also directed FSI’s Center on Democracy, Development, and the Rule of Law (CDDRL) from 2005 to 2009.

During his four years leading CDDRL, McFaul launched the Draper Hills Summer Fellowship program for mid-career lawyers, politicians, advocates and business leaders working to shore up democratic institutions in their home countries. He also established CDDRL’s senior honors program.  From 1992-1994, McFaul also worked as a Senior Research Fellow at FSI’s Center for International Security and Cooperation (CISAC).

“I am thrilled to be assuming a leadership role again at FSI,” McFaul said.  “FSI has become one of the premier institutions in the country for policy-relevant research on international affairs.  I look forward to using my recent government experience to deepen further FSI’s impact on policy debates in Washington and around the world.”

Arvin said McFaul’s previous positions at FSI and CDDRL will make for a smooth transition in the institute’s leadership.

“His familiarity with FSI’s history and infrastructure will allow him to start this new position with an immediate focus on the institute’s academic mission,” she said.

McFaul is also the Peter and Helen Bing Senior Fellow at the Hoover Institution, and plans to build on his long affiliations with both Hoover and FSI to deepen cooperation between these two premier public policy institutions on campus.

He has written and co-authored dozens of books including Advancing Democracy Abroad: Why We Should, How We Can; Transitions To Democracy: A Comparative Perspective (with Kathryn Stoner); Power and Purpose: American Policy toward Russia after the Cold War (with James Goldgeier); and Russia’s Unfinished Revolution: Political Change from Gorbachev to Putin.

“In so many ways, Mike represents the best of FSI,” said Cuéllar, who has held leadership positions at FSI since 2004 and begins his term on the California Supreme Court in January. “He knows the worlds of academia and policy extremely well, and will bring unique experience and sound judgment to his new role at FSI.”

McFaul currently serves as a news analyst for NBC News, appearing frequently on NBC, MSNBC, and CNBC as a commentator on international affairs. He also appears frequently on The Charlie Rose Show and The Newshour, as well as PBS and BBC radio programs. He has recently published essays in Foreign Affairs, The New York Times, Politico, and Time. 

McFaul was one of the first U.S. ambassadors to actively use social media for public diplomacy. He still maintains an active presence on Facebook at amb.mcfaul and on Twitter at @McFaul.

McFaul received his B.A. in International Relations and Slavic Languages and his M.A. in Russian and East European Studies from Stanford University in 1986.  As a Rhodes Scholar, he completed his D. Phil. in International Relations at Oxford University in 1991.

“Since coming here in 1981 as 17-year-old kid from Montana, Stanford has provided me with tremendous opportunities to grow as a student, scholar, and policymaker,” McFaul said. “I now look forward to giving back to Stanford by contributing to the development of one of the most vital and innovative institutions on campus.” 

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."
