"The author explores the interactions among food systems, diets, human health, and the climate crisis. Drawing on decades of hands-on research projects in Africa, Asia, Europe, and the Americas, she describes how food systems must evolve to promote healthy, sustainable, and equitable diets"--

Originally delivered as the Stegner Lecture at the 2020 annual symposium of the Wallace Stegner Center for Land, Resources and the Environment, Jessica Fanzo here explores how, in the context of the broad global trends of population growth, climate crisis, and inequitable food availability, food systems need to be re-oriented to ensure they can produce enough food to nourish the world. This re-orientation includes moving toward on-farm sustainable food production practices, decreasing food loss and waste, addressing poverty by creating jobs and decent livelihoods, and providing safe, affordable, and healthy diets for everyone. At the same time, food systems must decrease the pressure on biodiversity loss, conserve land and water resources, minimize air and water pollution, and lower greenhouse gas emissions. This is a lot to ask of an entrenched system. Food policy is central to changing systems, and bold policies must be applied to accelerate and incentivize economic, societal, and technological transformations towards a more socially just and sustainable global food system. But policy decisions come with synergies, trade-offs, and sometimes unexpected consequences. In a world of uncertainty, we must seek global solutions to human and planetary health.

Ensuring optimal diets and nutrition for the global population is a grand challenge fraught with many contentious issues. To achieve food security for all and protect health, we need functional, equitable, and sustainable food systems. Food systems are highly complex networks of individuals and institutions that depend on governance and policy leadership. This book explains how interconnected food systems and policies affect diets and nutrition in high-, middle-, and low-income countries. In tandem with food policy, food systems determine the availability, affordability, and nutritional quality of the food supply, which influences the diets that people are willing and able to consume. Readers will become familiar with both domestic and international food policy processes and actors, and they will be able to critically analyze and debate how policy and science affect diet and nutrition outcomes.

This open access book is the result of an expert panel convened by the Cornell Atkinson Center for Sustainability and Nature Sustainability. The panel tackled the seventeen UN Sustainable Development Goals (SDGs) for 2030 head-on, with respect to the global systems that produce and distribute food. The panel’s rigorous synthesis and analysis of existing research leads compellingly to multiple actionable recommendations that, if adopted, would simultaneously lead to healthy and nutritious diets, equitable and inclusive value chains, resilience to shocks and stressors, and climate and environmental sustainability.

"This report presents summaries of a series of case studies that were commissioned by the UNSCN and examined the nutrition sensitivity of agriculture and food policies in eight countries, as well as how the policies influence dietary, nutritional and health outcomes. The eight countries studied include Brazil, Malawi, Mozambique, Nepal, Senegal, Sierra Leone, south Africa and Thailand."--Page 7 du document résumé, format papier.
