Hunger touches the lives of people throughout the world, from the affluent Bay Area to the most impoverished regions of rural Africa. Food security – the availability of plentiful, nutritious, and affordable food – is a pressing issue for rich and poor countries alike as the world population moves toward 9 billion by mid-century.

In her new book The Evolving Sphere of Food Security (Oxford University Press, August), Professor Rosamond Naylor takes a holistic approach to the question of how to feed the world. Naylor, a professor of environmental earth system science and director of the Center on Food Security and the Environment (FSE), convened 18 colleagues from across Stanford’s diverse disciplines to shed light on the interdependent issues that affect global food security.

Throughout its 14 chapters, and a foreword by former United Nations Secretary-General Kofi Annan, the book takes up two important questions: How does the challenge of achieving food security change as countries develop economically? And how do food and agriculture policies in one country affect nutrition, food access, natural resources and national security in other countries?

Collaboration across disciplines

Naylor, who edited the volume and co-authored several chapters, explained that The Evolving Sphere of Food Security is the first book of its kind to engage faculty and scholars from across Stanford’s campus on issues of global hunger.

Professor Rosamond Naylor

“This book grew out of a recognition by Stanford scholars that food security is tied to security of many other kinds,” said Naylor, who is also William Wrigley Senior Fellow at the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment. “Food security has clear connections with energy, water, health, the environment and national security, and you can’t tackle just one of those pieces.”

Stanford has a long history of fostering cross-disciplinary work on global issues. It is in this spirit that the idea for the book was born, Naylor said. The book weaves together the expertise of authors from the fields of medicine, political science, engineering, law, economics and climate science.

“Stanford was the ideal place for this project. A book like this exemplifies how collaborative, interdisciplinary research can be greater than the sum of its parts,” Naylor said. “We have painted a much more inclusive picture of food security than if we had approached these questions from only one discipline.”

Rooted in field research

Another unique feature of the book is that each author’s insights are shaped by years of hands-on research and policymaking experience around the world.

Several authors, for example, have been instrumental in shaping U.S. and global food policy for decades. Walter Falcon, professor emeritus of economics and the deputy director of FSE, traces his career as an agricultural economics advisor to the Indonesian government, where he witnessed the country’s dramatic improvements in combating hunger and poverty since the 1960s.

Political science professor Stephen Stedman recounts his experience as a security policy advisor to the United Nations during the 2000s. Recognizing that food insecurity can exacerbate civil conflict, weaken governments and threaten international stability, Stedman worked to integrate food security into traditional security agendas.

Other authors have spent many years working in East Asia, Africa, South America, the Middle East and Europe. As a whole, said Naylor, the team has conducted well over a hundred years’ worth of field research all over the world.

Challenges evolve as countries develop

A recurring theme throughout the book – also reflected in its title – is the evolving nature of the food security challenges countries face as they move through stages of economic growth. At low levels of development, countries struggle to meet people’s basic needs. For example, Naylor’s chapter on health, co-authored with Eran Bendavid (medicine), Jenna Davis and Amy Pickering (civil and environmental engineering), describes a recent study showing that poor nutrition and rampant disease in rural Kenya is closely tied to contaminated, untreated drinking water. Addressing these essential health and sanitation issues is a key first step toward food security for the poorest countries.

As nations rise above the bottom rungs of development, they encounter new challenges. Scott Rozelle, director of the Rural Education Action Program, warns that middle income countries like China now face a “second food security crisis” of widespread micronutrient deficiency. Recent rapid economic and agricultural advancements have largely solved the problem of supplying sufficient calories. But this progress masks what Rozelle describes as “hidden hunger,” or a lack of vitamins and minerals that impedes kids’ school performance and could slow China’s long-term growth. Even in rich countries like the U.S., said Naylor, malnutrition can be a drag on educational and economic performance.

Developed countries face other unique tradeoffs in the use of resources for food production. In his chapter on water institutions, Buzz Thompson, professor of law and co-director of the Woods Institute, explains that conflicts over water increase between smallholder and industrial users as countries develop. Eric Lambin, professor of environmental earth system science, and Ximena Rueda, research associate in earth sciences, offer the paradox that as countries grow wealthier, changing patterns of agricultural land use may actually worsen food security by fueling the spread of obesity and diabetes.

At its core, said Naylor, The Evolving Sphere of Food Security is about more than economic and policy trends. “The book puts a human face to food security, because hunger is an intensely human experience,” she said. “This book tells an integrated story about people’s lives, and how they are shaped by resource use and the policy process around global food security.”

Fourteen Stanford researchers addressing global poverty through a range of academic disciplines are receiving a total of $4.6 million in awards from the university-wide Global Development and Poverty (GDP) initiative.

Their projects, which are the first to be funded by the GDP, deal with challenges of health, violence, economics, governance and education in the developing world.

“GDP seeks to transform scholarly activity and dialogue at Stanford around the topic of global poverty, so that the university may have a greater impact on poverty alleviation in developing economies,” said GDP faculty co-chair Jesper B. Sørensen. “By focusing on placing a small number of big bets, GDP encourages researchers to think big, and to move beyond the conventional way of doing things. We are thrilled by the inaugural set of awardees, as they demonstrate the creative, inter-disciplinary approaches that will make Stanford a leader in this area.”

The GDP initiative is part of the Stanford Institute for Innovation in Developing Economies (SEED) and is administered in partnership with Stanford's Freeman Spogli Institute for International Studies (FSI). The GDP is co-chaired by Sørensen, the faculty director for SEED and the Robert A. and Elizabeth R. Jeffe Professor of Organizational Behavior at the Graduate School of Business; and Mariano-Florentino Cuéllar, senior fellow and director of FSI and the Stanley Morrison Professor at Stanford Law School.

SEED, which seeks to alleviate poverty by stimulating the creation of economic opportunities through innovation, entrepreneurship and the growth of businesses, was established in 2011 through a generous gift from Robert King, MBA '60, and his wife, Dorothy.

Through complementary areas of focus, GDP funding and other SEED research initiatives will stimulate research, novel interdisciplinary collaborations and solutions to problems of global poverty and development. GDP research aims to pursue answers to crucial questions that are essential to an understanding of how to reduce global poverty and promote economic development. That includes governance and the rule of law, education, health, and food security – all of which are essential for entrepreneurship to thrive. By contrast, other SEED research focuses on innovation, entrepreneurship, and the growth of businesses in developing economies.

Since 2012, SEED’s Entrepreneurship and Innovation in Developing Economies Award program also has doled out 22 awards and seven PhD fellowships to help support and scale businesses in developing economies. Among the $1 million in funded projects were studies of how to improve the livelihoods of small-holder cacao farmers throughout the tropics; how to identify startups with high job- and wealth-creating potential in Chile; how political accountability affects the ability to attract investment in Sierra Leone; and how managerial practices affect trade entrepreneurship in China.

First GDP Awards

The first 14 GDP award recipients are professors of economics, political science, law, medicine, pediatrics, education and biology, and senior fellows from FSI, the Woods Institute, and the Stanford Institute for Economic Policy Research (SIEPR).

“Each of these projects cuts across disciplines, reflects innovative thinking, and has the potential to generate crucial knowledge about how to improve the lives of the poor around the world,” Cuéllar said. “These projects, along with a variety of workshops engaging the university and external stakeholders, will help us strengthen Stanford’s long-term capacity to address issues of global poverty through research, education and outreach.”

Among the award recipients is Pascaline Dupas, an associate professor of economics and senior fellow at SIEPR. Dupas, along with faculty from the Center for Health Policy and Center on Democracy, Development and the Rule of Law, will launch the Stanford Economic Development Research Initiative using GDP funds.  This initiative will focus on collecting high-quality institutional and individual-level data on economic activity in a number of developing countries over the long term, and making these data available to scholars around the world.

Beatriz Magaloni, an associate professor of political science and senior fellow at FSI, is receiving an award to lead a team focused on criminal violence and its effects on the poor in developing economies, and the practical solutions for increasing security in those regions.

Douglas K. Owens, a professor of medicine and FSI senior fellow, was awarded an award to help him lead a team that will develop models to estimate how alternative resource allocations for health interventions among the poor will influence health and economic outcomes.

Stephen Haber, a professor of political science and history and a senior fellow at the Hoover Institution, received an award to bring together Stanford researchers interested in examining the long-term institutional constraints on economic development. Their goal will be to provide policymakers with a framework for determining the conditions under which particular innovations are likely to have positive payoffs, and the conditions under which resources will likely be wasted.

Other projects will address the educational impacts of solar lighting systems in poor communities; identifying interventions to improve the profits and safety among poor, smallholder pig farmers in Bangladesh and China; the role of law and institutions in economic development and poverty reduction; and how to rethink worldwide refugee problems. Awards are also being provided to researchers focused on microfinance, online education and teacher training.

The project proposals were reviewed by an interdisciplinary faculty advisory council chaired by Cuéllar and Sørensen. 

“We were very encouraged by the impressive number of project proposals from a wide range of areas and are looking forward to introducing several new capacity and community-building activities in the fall,” Sørensen said.. “This wide range of research initiatives will form a vibrant nucleus for Stanford’s growing community of scholars of global development and poverty.”

Has the global food price bubble  burst, and if so, does it matter? In the first installment of FSE's new Food and Nutrition Policy Symposium Series, Professor Thomas Hertel of Purdue University and Professor Johann Swinnen of Leuven University outlined global trends in the cost of food, and explained how a drop in prices after the food price shocks of 2007-2008 might affect global politics and economics.

What drives food prices?

As population growth and rising incomes put pressure on the global food supply, many scholars consider high food costs to be the "new normal," especially following the food price shocks of 2007-2008. Professor Thomas Hertel challenged this view, saying that "To look forward 45 years, you have to look back 45 years" at what factors actually impact food prices.

Prices for many food commodities fell between 1961 and 2006, despite strong population and income growth, because the world was able to triple crop production during the same period. Since the recent price spikes, the "food price bubble" seems to have burst, with prices falling steadily since 2009.

Although population will continue to grow over the next several decades, the rate of growth is slowing worldwide and is mostly concentrated in developing countries, where per capita purchasing power is relatively low. This minimizes the pressure that population growth puts on the global food supply.

Economic factors may be more influential. "For the first time in history," Hertel said, "income will surpass population as a driver of global food demand." As countries move up the income scale, they consume richer diets of input-intensive products like meat, dairy and processed foods.

Energy prices also influence global food costs. As oil and gas prices rise, demand grows for alternative fuels like ethanol. Half of the increase in corn production over the past several decades came from the growing demand for ethanol, which was fueled by government mandates and which drove up the global price of corn. These mandates have been rolled back in recent years, however, and demand growth for biofuels has waned.

Hertel added that issues around climate change, urbanization, water supply, food waste and deforestation may also impact global food prices in the future.

Many scholars point to crop yields as a way to close the gap between food supply and demand and keep prices low. But Hertel cautioned that scientists and policymakers may be constrained by technical and economic limits.

To further increase yields "is a bigger job than simply doing some more science in the lab," Hertel said. But he noted with optimism that new investments in research and development have risen sharply from both the public and private sector, particularly in countries like China, India and Brazil where food security is a pressing issue. 

Impacts of the food price bubble

Professor Johann Swinnen explained that if the food price bubble has in fact burst, the next several years are likely to bring a shift in the politics and economics of global food issues.

The recent bubble coincided with an increase in both policy attention and donor funding to combat food insecurity - a focus that has benefitted both farmers and consumers, but that could wane as prices fall.

While the high prices of 2007-2008 benefited farmers, they in turn hurt low-income consumers in urban areas. And because people in high-density areas find it easier to organize and voice their concerns over government policies, they are more likely to capture media attention.

This "urban bias," as Swinnen described it, influenced policymakers to respond to the heavy media coverage. His team found that after 2007, agricultural funding from the World Bank, United Nations Food and Agriculture Organization (FAO) and the International Maize and Wheat Improvement Center (CIMMYT) all rose sharply. The percentage of global development aid targeted toward agriculture also grew.

Swinnen described the social and political conditions of 2007-2008 as a "perfect storm" that shifted the attention of policymakers toward global food security investments. Paradoxically, Swinnen explained, this policy response to urban unrest over food prices ultimately benefitted both rural and urban populations, by boosting agricultural investments for food producers while also helping lower costs for consumers.

 The Food and Nutrition Policy Symposium Series will run for three years and will consist of a total of ten lectures spanning a wide range of issues around global food and nutrition policy. It is funded by Zachary Nelson, '84 and Elizabeth Horn. The series follows on the successful two-year Global Food Policy and Food Security Symposium Series which concluded in May 2013 and was funded by the Bill and Melinda Gates Foundation.

Scholars, law enforcement officials, business leaders and community activists will meet next week at Stanford to examine violence and policing in Latin American and the United States.

A two-day conference beginning April 28 will highlight the work of entrepreneurs and grassroots organizations trying to reduce violence and rebuild civil society. The gathering is hosted by the Program on Poverty and Governance (PovGov) at the Center on Democracy, Development and the Rule of Law. It is hosted in partnership with the Bill Lane Center for the American West, the Center for Latin American Studies, the ‘Mexico Initiative’ at the Freeman Spogli Institute for International Studies (FSI) and the Center for International Security and Cooperation.

"Violence linked to drug trafficking, gang wars and criminality is one of the leading barriers to development that effects the lives of millions in Latin America,” said Beatriz Magaloni, an associate professor of political science who directs PovGov, a program that studies the links between public action, goverance and poverty.

“The conference brings together people who have dealt with these problems in cities in Latin America and in the U.S. Seldom is the case that we bring to campus practitioners with first-hand experience dealing with some of the most pressing problems the hemisphere is confronting,” said Magaloni, who is also a senior fellow at FSI. 

The first day of the conference will feature a panel with Jose Galicot, the driving force of Tijuana Innovadora, a movement that helped Tijuana recover from devastating criminal activity and violence the last four years. Galicot will be joined by Jailson Silva, from Observatório of Favelas, one of the most reputable grass-roots organizations in the slums of Rio that undertakes research, consultancy and public actions focused on the city's favelas.

Many violence-plagued cities in the U.S. have implemented innovative initiatives to address the challenge that have included community policing tools and youth violence interventions. Similar initiatives are also taking place in Latin America with varying degrees of success. One of the goals of the conference is to get practitioners to share their experiences and best practices to reduce violence in major cities.

One of three featured keynote speakers, Sergio Fajardo, the current governor of Antioquia, Colombia, will speak on April 29 and help build the foundation for such dialogue. From 2003 to 2007, Fajardo implemented an effective strategy to reduce the level of violence in Medellin while he was mayor of the Colombian city.

By providing alternatives to illicit work, allocating resources to the most disadvantage areas, reclaiming public spaces and fostering dialogue among different sectors of society to create a sense of collective ownership, Fajardo transformed Medellin.

The two other keynotes include Mariano Beltrame, minister of security of Rio de Janeiro who is credited for the enactment and implementation of the Pacification Police Unites to reduce violence in the favelas of the city and Hector Robles, major of the municipality of Zapopan who has implemented various innovative policies to give better opportunities to the youth in Mexico, including an initiative called Jovenes con Porvenir (Youth with a Bright Future). 

The conference will also bring together police chiefs from Brazil and the U.S. to share their experiences and insights on grassroots implementation of initiatives designed to reduce violence. General Commander of Operations, Coronel Paulo Henrique, from the military police of Rio de Janeiro, Brazil, and Chief Eric Jones from Stockton, CA will be speaking on a panel titled, “’Pacification’ Strategies and Policing” on day two of the conference. Tony Farrar, chief of police for the city of Rialto, CA will be joined by Robert Chapman, deputy director of Community Policing Advancement and others to present on police accountability and gang violence in the U.S shortly thereafter.  

The conference will build upon a PovGov research project that is focused on the Brazilian military police in Rio de Janeiro. Targeting an important initiative in the city's favelas, the "Pacifying Police Units", the ongoing project investigates the use of lethal force by the police and reforms aimed at controlling violence.

A number of conference sessions will be led by CDDRL faculty members and affiliates, including: FSI Director Mariano-Florentino Cuéllar; Francis Fukuyama, the Olivier Nomellini Senior Fellow; FSI senior fellow and CDDRL affiliated faculty member Alberto Díaz-Cayeros; and former President of Peru and CDDRL Visiting Lecturer Alejandro Toledo. A conference report will be made available following the event.

Sessions will be held at Stanford University's Bechtel Conference room in Encina Hall on Monday, April 28 and the Alumni Center on Tuesday, April 29.  All sessions are free and open to the public. Please RSVP here to attend. A complete agenda can be found here.

Zack Bonzell came to Stanford with a strong interest in human biology and political science. Last summer, the undergraduate had the chance to fuse his interests while doing field research with faculty at the university’s Freeman Spogli Institute for International Studies (FSI). 

During a two-week internship, he travelled to Guatemala with FSI senior fellows Paul Wise, Beatriz Magaloni, Alberto Díaz-Cayeros and Scott Rozelle to learn about the country’s rural health care system by shadowing doctors and interviewing mothers in an impoverished area about the issues leading to the area’s high rates of child malnutrition.

“That experience was an ideal way to blend my interests and gave me a better idea of how to craft my course of study at Stanford,” said Bonzell, who is now a junior. “One of the things that really struck me was when Paul Wise said the health outcomes we were seeing are the result of extreme material deprivation. These people are sick because they are poor. That gave me more of an interest in political economy.”

FSI is now expanding its educational opportunities for students, like Bonzell, who want to do research on global issues in Asia, Latin America, Europe and Africa.

The Stanford Global Student Fellows program (SGSF) is being funded in large part through a $1.25 million anonymous gift that will help grow existing programs and create new offerings for graduates and undergraduates.

“This program deepens FSI’s commitment to its mission of educating the next generation of leaders in international affairs,” said FSI Director Mariano-Florentino Cuéllar. “It also offers outstanding opportunities for Stanford students to work closely with the leading thinkers on global policy issues.”

The program, which is part of FSI’s efforts to expand student opportunities, will build on the institute’s undergraduate mentorship programs that allow students to work on faculty research projects each quarter. Those positions will now be available during the summer. Some of the positions will be connected to projects in FSI’s new International Policy Implementation Lab, an initiative that gives students a close-up view of how academics and policy influencers can address some of the world’s thorniest issues.

Building on FSI’s experience placing students in research opportunities, the program will create and expand summer field research internships. The two- to six-week internships this summer will give undergraduates the opportunity to work with FSI senior fellows in China, Guatemala, India and Mexico who study global health, conflict resolution, governance and poverty reduction.  In coming years, the program will likely include additional fieldwork projects in Rwanda, Tanzania and Brazil. The SGSF program covers all travel expenses for students and provides students with an opportunity to work closely with a faculty member and a team of other students on an ongoing research project addressing real-world problems in a specific region. 

“What makes FSI such an incredible institution is that it attracts faculty who have very pragmatic interests,” Bonzell said. “It seeks to wed academic work with a more direct impact, and there’s a lot of potential for more students to think along similar lines.”

The Stanford Global Student Fellows will also allow FSI to work closely with its partners, including the Program in International Relations, the Haas Center for Public Service, and Stanford in Government to provide opportunities for graduate and undergraduate students.

One of the program’s new initiatives geared toward undergraduates is the Global Policy Summer Fellowships. The fellowships help secure placement and a $6,000 stipend for students interested in interning at international policy and international affairs organizations. This summer, The Europe Center at FSI is placing students at the Center for European Policy Studies and Bruegel, two Brussels-based think tanks. Future positions will be created with six offerings abroad and two based in the United States.including the Program in International Relations, the Haas Center for Public Service, and Stanford in Government to provide opportunities for graduate and undergraduate students. 

The Stanford Global Student Fellows program will also commit $400,000 to create a Mentored Global Research Fellowship that will provide research opportunities for students to conduct their own overseas research under the close mentorship of a faculty member. The program will award stipends of $6,000 for summer undergraduate projects and $9,000 for summer graduate projects, and $1,500 for smaller projects executed during the school year.

The faculty advisory committee overseeing the development and implementation of these new programs includes Scott Rozelle, the Helen F. Farnsworth Senior Fellow and the co-director of FSI’s Rural Education Action Program; Stephen Stedman, a senior fellow at FSI and the deputy director of CDDRL; and Lisa Blaydes, assistant professor of political science.

The application deadline for all summer programs is Feb. 28, 2015. The deadline to apply for academic quarterly programs is the end of the first week of each quarter, beginning in the fall of 2014. 

For more information, students should contact Elena Cryst at ecryst@stanford.edu and watch for postings on FSI’s student program Facebook page. Students can also sign up for the program’s distribution and announcement list.

Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, according to new computer models by Stanford scientists.

This colocation approach could prove especially useful in sunny, arid regions such as the southwestern United States where water is scarce, said Sujith Ravi, who is conducting postdoctoral research with professors David Lobell and Chris Field, both on faculty in environmental Earth system science and senior fellows at the Stanford Woods Institute for the Environment. David Lobell is associate director and Chris Field is a core faculty affiliate at the Center on Food Security and the Environment.

“Colocated solar-biofuel systems could be a novel strategy for generating two forms of energy from uncultivable lands: electricity from solar infrastructure and easily transportable liquid fuel from biofuel cultivation,” said Ravi, lead author of a new study published in a recent issue of the journal Environmental Science & Technology that details the idea.

Photovoltaic (PV) solar farms run on sunlight, but water is required to remove dust and dirt from the panels to ensure they operate at maximum efficiency. Water is also used to dampen the ground to prevent the buildup and spread of dust. Crops planted beneath the solar panels would capture the runoff water used for cleaning the PV panels, thus helping to optimize the land. The plants’ roots would also help anchor the soil, and their foliage would help reduce the ability of wind to kick up dust.

Computer simulations of a hypothetical colocation solar farm in California’s San Bernardino County by Ravi and colleagues suggest that these two factors together could lead to a reduction in the overall amount of water solar farms need to operate. "It could be a win-win situation," Ravi said. “Water is already limited in many areas and could be a major constraint in the future. This approach could allow us to produce energy and agriculture with the same water.”

But which crops to use? Many solar farms operate in sunny but arid regions that are very not hospitable to most food crops. But there is one valuable plant that thrives at high temperatures and in poor soil: agave. Native to North and South America, the prickly plant can be used to produce liquid ethanol, a biofuel that can be mixed with gasoline or used to power ethanol vehicles. "Unlike corn or other grains, most of the agave plant can be converted to ethanol," Ravi said.

The team plans to test the colocation approach around the world to determine the ideal plants to use and to gather realistic estimates for crop yield and economic incentives.

“Sujith’s work is a great example of how thinking beyond a single challenge like water or food or energy sometimes leads to creative solutions,” said Lobell, who is a coauthor on the new study. “Of course, creative solutions don’t always work in the real world, but this one at least seems worthy of much more exploration.”
