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.
