China plays a dominant role in the global seafood trade: its capture fisheries output is the highest in the world, estimated at 15.6 million tons in 2010, and its aquaculture production is three times as high (almost 48 million tons in 2010, roughly two-thirds of the world’s total production). The country also leads the world in aquafeed and fishmeal use, fishmeal imports, fish and shellfish consumption and seafood exports.
Rosamond (Roz) Naylor has been named the first holder of the new William Wrigley Professorship in the School of Earth Sciences. Since 2006 Naylor has directed the Center on Food Security and the Environment, within the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment. She is also associate professor, by courtesy, of Economics at Stanford.
"Professorships are the best way to recognize faculty for their superior leadership and commitment to research, teaching, service to the university and service to humanity," said Pamela Matson, dean of the School of Earth Sciences at Stanford. "Roz epitomizes these qualities - she is incredibly fitting as the inaugural holder of the William Wrigley Professorship."
Walter Falcon, professor (emeritus) of economics at Stanford and a longtime research collaborator of Naylor's, added: “All of Roz’s colleagues are delighted at her selection. She has long been a thought leader on food security issues, she has limitless energy, and she has an extraordinary capacity for bringing scholars together at Stanford and beyond.”
The new William Wrigley Professorship is supported by Mrs. Julie Ann Wrigley, AB '71 (Anthropology) and Ms. Alison Wrigley Rusack, AB '80 (Communication).
Naylor's research focuses on economic and biophysical dimensions of food security, and the environmental impacts of crop and animal production. She has been involved in many field-level research projects around the world and has published widely on issues related to intensive crop production, aquaculture and livestock systems, biofuels, climate change, food price volatility, and food policy analysis. At Stanford, Naylor teaches courses on the World Food Economy, Human-Environment Interactions, and Sustainable Agriculture.
Naylor currently serves on the Scientific Advisory Board for the Beijer Institute in Stockholm, is a Science Advisor for United Nation’s Secretary General Ban Ki-Moon’s initiative on Sustainable Development (Sustainable Agriculture section), and trustee of The Nature Conservancy California Chapter. Additionally, she serves on the editorial board of the journals Global Food Security and Journal on Food Security. Naylor received her B.A. in Economics and Environmental Studies from the University of Colorado, her M.Sc. in Economics from the London School of Economics, and her Ph.D. in applied economics from Stanford University.
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.
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."
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."

I graduated from Stanford in 2012 with a B.S. in Earth Systems, focusing on marine science. I also earned a Master’s of Environmental Science and Management from the Bren School at UC Santa Barbara in 2014, where I studied environmental economics and policy. My academic background is quite diverse and interdisciplinary. I have worked on projects related to measuring GHG emissions from thawing subsea permafrost in the Arctic, nutrient cycling in pre-contact Hawaiian agricultural systems, and marine spatial planning for industrial aquaculture in Southern California. I am currently in my first year as a PhD student in the Emmett Interdisciplinary Program in Environment and Resources (E-IPER), where my research focuses on evaluating the role seafood will play in the future of food production. In particular, I am interested in how market forces will shape the demand for, and production of seafood from both wild capture fisheries and aquaculture, how these changes will affect the environmental impacts of food production, and how current and future policy can incorporate these understandings to achieve food security while incurring minimal environmental cost.
Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. However, aquaculture’s reliance on terrestrial crops and wild fish for feeds, its dependence on freshwater and land for culture sites, and its broad array of environmental impacts diminishes its ability to add resilience. Feeds for livestock and farmed fish that are fed rely largely on the same crops, although the fraction destined for aquaculture is presently small (!4%). As demand for high-value fed aquaculture products grows, competition for these crops will also rise, as will the demand for wild fish as feed inputs. Many of these crops and forage fish are also consumed directly by humans and provide essential nutrition for low-income households. Their rising use in aquafeeds has the potential to increase price levels and volatility, worsening food insecurity among the most vulnerable populations. Although the diversification of global food production systems that includes aquaculture offers promise for enhanced resilience, such promise will not be realized if government policies fail to provide adequate incentives for resource efficiency, equity, and environmental protection.
From May 13-15, the Center on Food Security and the Environment and the Lenfest Ocean Program welcomed leading Chinese and international scientists to the Stanford Center at Peking University in Beijing, to share research and insights on the role of ocean fisheries, aquaculture, and marine ecosystems for improving food security in China.
Given China’s demographic changes, evolving nutritional requirements, and dominant role in global fisheries, the key question of the symposium was whether marine ecosystems can be managed adequately to support the country’s future vision for domestic food security.
Nearly 30 participants from around the world shared research on the provision of wild fish for direct human consumption and for animal feeds. Participants also shared insights on China’s aquaculture sector, including the tradeoffs involved in using wild fish in aquaculture feed.
