In a lecture to the Stanford community Tuesday night, Professor Sir Gordon Conway argued that sustainably intensifying agriculture, especially in Africa, is the only way to feed a growing global population without greatly expanding the amount of land used for farming. Sir Gordon is an agricultural ecologist and was an early pioneer of sustainable agriculture while working in Malaysia in the 1960s. He is now a professor of international development at Imperial College London and the director of Agriculture for Impact, a project funded by the Bill and Melinda Gates Foundation.

Sir Gordon's lecture, "Can Sustainable Intensification Feed the World?" was the second installment of the Food and Nutrition Policy Symposium Series sponsored by the Center on Food Security and the Environment.

Sir Gordon described three major challenges to ensuring future global food security: food prices are higher and more volatile, one billion people are malnourished (including 1 in 5 children), and rising demand means that 60 to 100 percent more food will be needed to feed the world by 2050. Solving the food security crisis will mean improving both the quantity and the nutrition of food, at stable and affordable prices, in the face of major challenges.

These challenges include factors on the demand side of the global food economy, such as population growth, changing diets, and the use of crops for biofuels. Supply side factors like high fertilizer prices, climate change, and scarcity of land and water put even more pressure on the food system. 

The solution, Sir Gordon said, is agricultural intensification, a set of practices that allow farmers to produce more food with existing land and water. Sustainability is a key component, so that intensification does not also raise greenhouse gas emissions, deplete soil quality, or damage the resilience of farming systems. Sustainable intensification will be especially important in Africa, said Sir Gordon, where population growth and dietary changes will be most dramatic, and where currently crop yields are far below most other areas of the world.

 Farmers, scientists and policymakers can take several approaches to sustainable intensification. An ecological approach includes practices that safeguard environmental resources and reduce farmers’ dependence on chemicals like herbicides and pesticides, such as through organic farming, integrated pest management, agroforestry or conservation agriculture. A genetic intensification approach includes developing better plant varieties, with traits that promote more sustainable agriculture by resisting pests and diseases, or that provide more nutrition. A third approach is socio-economic intensification of agriculture, through the development of farmers’ cooperatives, better links between farmers and markets, and improved access by farmers to insurance and credit.

The goal, Sir Gordon said, is to help farmers “build resilient livelihoods” that will withstand economic and environmental shocks in the coming decades. Good science is important, but strong political leadership, especially within Africa, will be just as crucial.

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. 

Rosamond Naylor, director of the Center on Food Security and the Environment, delivered the keynote address to The University of Vermont's Food Systems Summit in Burlington, VT on June 17-18, 2014. Naylor is the editor of The Evolving Sphere of Food Security (forthcoming, Oxford University Press), the first book of its kind to engage thought leaders from across Stanford’s campus to explore the causes and symptoms of complex topic like global hunger. She will discuss the book's insights on the ways that food security is tied to security of many other kinds: energy, water, health, climate, the environment, and national security. 

The Evolving Sphere of Food Security is available for pre-order from Oxford University Press.

Seeds of Sustainability tackles a central challenge of sustainable development: agricultural modernization. It is cutting edge not because the issue itself is new, but rather the level of integration the authors attempted and the innovative process they used. The volume summarizes the findings and reflects on the process of a highly interdisciplinary team of researchers, integrating perspectives from: biogeochemistry, atmospheric sciences, land-use change, institutions, agronomy, economics, and knowledge systems. The foundation of the work is rigorous, grounding its findings in multiple peer reviewed publications, while not hesitating to point out gaps or unresolved issues. Seeds of Sustainability includes an in depth historical analysis, which captures issues of path dependence. It demonstrates both originality and critical reflectiveness in its efforts to engage practitioners in the conceptualization and execution of its research, and the implementation of its findings. And almost uniquely in our collective experience, it speaks seriously, frankly, and insightfully to the challenges of institutionalizing the sort of work it reports on.
