Our global food system is largely based on unsustainable industrial agricultural practices, is a major source of greenhouse gas emissions, is controlled by a handful of large corporations and produces unhealthy food. Agroecology is a solution to these increasingly urgent problems. After decades of being dismissed by mainstream institutions and defended in obscurity by grassroots movements, some scientists and farmers, agroecology is suddenly in fashion. The United Nations Food and Agriculture Organization, government agencies and even corporations are jumping on the bandwagon. But, are they for the same agroecology as developed by pioneering farmers, scientists and peasant social movements, or are they seeking to co-opt the concept and give it different content? Rosset and Altieri, two of the world’s leading agroecologists, outline the principles, history and currents of agroecological thought, the scientific evidence for agroecology, how to bring agroecology to scale and the contemporary politics of agroecology.

'This is a timely and excellent book by two world leaders of agroecological thought and practice. In this highly readable book, Peter Rosset and Miguel Altieri offer a clear analysis of the principles of agroecology and its potential to address major social, economic and environmental challenges of food and farming in the 21st century. Most notably, the book demonstrates the importance of social organization, peasant agroecology schools and social movements for bringing agroecology to scale. By focusing on the contested nature of the science of agroecology and its contemporary politics, the authors invite the reader to embrace an agroecology that transforms — rather than conforms with — the dominant agri-food regime. A stimulating read!'

'Agroecology: Science and Politics by Peter Rosset and Miguel Altieri will be an important book that does an excellent job at summarizing what agroecology is as a science, a practice and a movement, as well as the debates that are currently going on regarding agroecology.'

'This small book has a very important message for the agroecology movement as well as for each of us as agroecologists. The scientific basis of agroecology and how agroecology confronts the industrial agriculture model is now broadly accepted, but how this approach can overcome the political and economic power of this model is much more controversial. This book clearly and forcefully states that agroecology must also address the politics of the food system, who has power and control, and how what might be called political agroecology must be included so that deep change can occur. We must heed this call to action!'
