Agroecology: Leading the Transformation to a Just and Sustainable Food System

Agroecology is at the forefront of transforming our food systems. This bestselling textbook provides the essential foundation for understanding this transformation in all its components: agricultural, ecological, economic, social, cultural, and political. It presents a case for food system change, explains the principles and practices underlying the ecological approach to food production, and lays out a vision for a food system based on equity and greater compatibility with the planet’s life support systems. New to the fourth edition:

• A chapter on Alternatives to Industrial Agriculture, covering the similarities and distinctions among different approaches to sustainable agriculture
• A chapter on Ecological Pest, Weed, and Disease Management
• A chapter on Urban and Peri-urban Agriculture
• A chapter on Agriculture and the Climate Crisis
• A revised analysis and critique of the food system’s embeddedness in the extractive capitalist world economy that reflects ideas in the emerging field of political agroecology
• Streamlined treatment of agroecology’s foundations in ecological science, making the text more compatible with typical course curricula

A Companion Website at https://routledgetextbooks.com/textbooks/9781032187105/ incorporates the entire contents of the updated practical manual Field and Laboratory Investigations in Agroecology, split into student and lecturer resources. These 24 sample investigations facilitate hands-on learning that involves close observation, creative interpretation, and constant questioning of findings.

Groundbreaking in its first edition and established as the definitive text in its second and third, the fourth edition of Agroecology captures recent developments in the field and forcefully applies the idea that agroecology is a science, a movement, and a practice. Written by a team of experts, this book will encourage students and practitioners to consider the critical importance of transitioning to a new paradigm for food and agriculture.

With graduate degrees in Botany and Ecology from the University of California, Santa Barbara, Stephen (Steve) R. Gliessman has accumulated more than 50 years of teaching, research, and production experience in the field of agroecology. His international experiences in tropical and temperate agriculture, small-farm and large-farm systems, traditional and conventional farm management, hands-on and academic activities, non-profit and business employment, and organic farming have provided a unique combination of experiences and perspectives to incorporate into this book. He was the founding director of the University of California, Santa Cruz, Agroecology Program, one of the first formal agroecology programs in the world, and was the Alfred and Ruth Heller Professor of Agroecology in the Department of Environmental Studies at UCSC until his retirement in 2012. He is the co-founder of the non-profit Community Agroecology Network (CAN) and currently serves on its board of directors. He is the editor of the international journal Agroecology and Sustainable Food Systems and dry farms organic wine grapes and olives with his wife Robbie in northern Santa Barbara County, California.

is Professor of Agroecology and Environmental Studies at the University of Vermont’s (UVM) Environmental Program and Department of Plant and Soil Science, where he also co-directs the Agroecology and Livelihoods Collaborative (ALC) with Martha Caswell. With degrees in Crop Science, Tropical Agroforestry, and Agroecology, he focuses his research and teaching on agroecology, agri-food systems, participatory action research (PAR), coffee agroecology, transdisciplinary research approaches, and social justice. At UVM he is also a faculty member of the Food Systems Graduate Program, fellow and steering committee member of the Gund Institute for Environment. He has more than 25 years of experience working with smallholder farmers and Indigenous communities in Latin America and collaborating in agroecology efforts across the world. He has authored or co-authored more than 60 peer-reviewed articles and chapters and edited three books. Ernesto was born and raised in El Salvador and maintains deep connections, in life and work, with his Central American roots.

is an agricultural entomologist and Lecturer of Agroecology and Environmental Studies in the Plant and Soil Science Department and Environmental Program at the University of Vermont. He also serves as the Education Coordinator of the Agroecology and Livelihoods Collaborative (ALC) and is the co-founder of the Vermont Entomology and Participatory Action Research Team (VEPART), also housed within the Department of Plant and Soil Science. With degrees in Chemistry, Bioscience, and Plant and Soil Science, Vic brings a broad perspective to his work as an agroecologist and teacher. Whether it is a high school classroom in Mexico City, a Master Gardener workshop on a New England farm, or an agroecology course on a university campus, he is always looking to create innovative learning communities built on trust, empathy, and the co-production of knowledge. When he is not in a classroom or on a farm, Vic is with his partner Carolina and son Nico tending to their many gardens and indulging in their respective culinary traditions of Italy and Mexico.

is a freelance editor, independent scholar, photographer, and naturalist. With experience in the natural sciences, a graduate degree in Sociology, and recognized achievement in the arts, he has developmentally edited more than two dozen books published by academic presses in fields ranging from environment and history to art and behavioral sciences. He has always tended a home garden, and the current two-decade gardening endeavor, in the foothills of the Sierra Nevada, supplies him and his wife Lisa with much of their food.
