Originally delivered as the Stegner Lecture at the 2020 annual symposium of the Wallace Stegner Center for Land, Resources and the Environment, this book 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. Fanzo discusses 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.

Our diets are going to change dramatically as global warming affects growing seasons and the availability of different foods around the world. Meanwhile, our foodways are among the biggest contributors to greenhouse gas emissions. To address these challenges Food in a Changing Climate demands we look beyond our plates to the roots of inequity in our food systems. It presents an unashamedly political agenda for'deep adaptation', focused on the rejuvenation and strengthening of local and regional food systems that have been steadily eroded in the name of economic efficiency. The colonial origins of fossil-fuel based food production and trade persist in the marginalisation of farmers, food workers, and fishers in a corporatized food system that promotes the exploitation of the environment, excess production, and hyper-consumerism. These factors contribute to climate change, poverty, and health inequities on a global scale. Drawing on case studies from around the world, this book illustrates how the commodification of food has made us particularly vulnerable to climate change, extreme weather events, and pandemics such as COVID19. These shocks reveal the danger of our reliance on increasingly complex supply chains - dominated by a decreasing number of mega-companies - for our food security. The unsustainability of the way we produce and eat food is clear. It has been for a long time. Food in a Changing Climate explores how we can cultivate resilient communities through the just application of new technologies, the recovery of traditional knowledges, and by building diversity to protect the livelihoods of food producers everywhere.

Population growth alone dictates that global food supplies must increase by over 50% in coming decades. Advances in technology offer an array of opportunities to meet this demand, but history shows that these can be fully realised only within an enabling policy environment. Sustaining Global Food Security makes a compelling case that recent technological breakthroughs can move the planet towards a secure and sustainable food supply only if new policies are designed that allow their full expression. Bob Zeigler has brought together a distinguished set of scientists and policy analysts to produce well-referenced chapters exploring international policies on genetic resources, molecular genetics, genetic engineering, crop breeding and protection, remote sensing, the changing landscape of agricultural policies in the world's largest countries, and trade. Those entering the agricultural sciences and those who aspire to influence public policy during their careers will benefit from the insights of this unique set of experiences and perspectives.
