The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

PREFACE AND ACKNOWLEDGMENTS To follow up on discussions held by the National Research Council’s Roundtable on Science and Technology for Sustainability, an ad hoc committee of experts was appointed to organize two workshops to address the sustainability challenges associated with providing food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, examined the empirical basis for past trends, the current situation, and projections for the future. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, explored a set of issues fundamental to assuring that food supplies can be increased to meet the needs of the world’s growing population—now expected to reach over 9 billion by 2050. The issues addressed during the workshops were timely, as food security and agricultural development have become priority topics for the international leaders meeting regularly at the Group of Twenty (G-20) as well as critical elements in the United Nations climate change negotiations launched in Copenhagen in 2009. In February 2011, the committee hosted the first workshop to review commonly used indicators for food security and malnutrition, poverty, and natural resources and agricultural productivity. The overarching objective of the first workshop was to contribute to the global effort towards sustainable food security through the improvement of indicators used to assess and monitor progress. The workshop offered an opportunity for dialogue among a small group of experts, including those responsible for key indicators of food security, key critics of those metrics, end users, and planning committee members. The workshop also sought to analyze methodological strengths and weaknesses and to discuss priorities for improving our understanding of the dimensions (quantitative, qualitative, and geographical) of the issues. The second workshop, held in May 2011, was designed to identify the major challenges and opportunities for change associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Estimates made by the United Nations predict that the world population will increase to 9.3 billion by 20501 and 70 percent more food will be required, posing a global sustainability challenge. While sustainable food security for all depends both on food supplies and assuring access to food, the second workshop focused specifically on assuring the availability of adequate food supplies. Workshop participants were asked to examine long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also discussed the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity due to changes in the climate. This report has been prepared by the committee as a factual summary of what occurred at the workshops, and the statements made do not necessarily represent positions of the workshops’ 1 New UN population estimates (for 2010) were released just at the time of our workshop. These new estimates suggested that by the end of the century the global population could reach 10.1 billion and 9.3 billion by 2050. See World Population Prospects 2010.

participants as a whole, the Science and Technology for Sustainability Program, or the National Academies. The workshops and report could not have come together without the help of many dedicated staff members. Pat Koshel and Emi Kameyama directed the project and coordinated the report. Marina Moses provided oversight. Jennifer Saunders and Dylan Richmond provided invaluable support and assistance with our two workshops and in preparing the final report. This report is the result of substantial effort and collaboration among several organizations and individuals. We wish to extend a sincere thanks to each member of the planning committee for his/her contributions in scoping, developing, and carrying out this project. The project was made possible by financial support from the Bill and Melinda Gates Foundation, the Syngenta Foundation for Sustainable Agriculture, and the U.S. Department of Agriculture. It also benefitted from the National Academies’ internal support, provided by the George and Cynthia Mitchell Endowment for Sustainability Science. This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the National Academies’ Report Review Committee. The purpose of this independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and to ensure that the report meets institutional standards for quality and objectivity. The review comments and draft manuscript remain confidential to protect the integrity of the process. I wish to thank the following individuals for their review of this report: Chris Barrett, Cornell University; Yurie Tanimichi Hoberg, The World Bank; Daniel Maxwell, Tufts University; Lynnette Neufeld, Micronutrient Initiative; and Sanjay Reddy, The New School for Social Research for Part I of the report; and William Easterling, The Pennsylvania State University; Keith Fuglie, U.S. Department of Agriculture; Brian Greenberg, InterAction; George Hornberger, Vanderbilt University; Rattan Lal, The Ohio State University; and Sara Scherr, EcoAgriculture Partners for Part II of the report. Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the content of the report, nor did they see the final draft before its release. Responsibility for the final content of this report rests entirely with the authors and the institution.
