In order for this paradigm shift to come about, agroecology must become a force for change that integrates research, practice, and social change in all parts of our food systems. 10 A diverse agroforestry system in the village of Cantagallo, Las Segovias, Nicaragua. A shade-grown organic coffee cash crop below a diverse cover of native and introduced trees, along with other associate crops, provides income, food, firewood, and environmental services such as biodiversity conservation, healthy soil, watershed protection, and carbon sequestration.

Serving this need is the social-change aspect of agroecology, which not only advocates for the changes that will lead to food security for all, but also seeks knowledge of the means by which these changes can be activated and sustained. Although each of these aspects of agroecology is critical, the bulk of this book is dedicated to the science of agroecology. In presenting this material, the book highlights the practical aspect by giving examples of how the science can be successfully applied. The social-change aspect of agroecology is not introduced until Section VI, after the reader has absorbed the full suite of ecological principles and practices that form the foundation of sustainable food systems.

Role of Agroecology Many scientists, researchers, and educators in the field of agroecology, and their colleagues in disciplines like agronomy, have long believed that their role is to come up with agricultural methods and systems that are more sustainable, more environmentally friendly, less input dependent, and less technology intensive than those of industrial agriculture. The assumption is that these methods and systems will then be adopted because they are superior when judged by any of various sets of criteria.
