Agroecology is the application of ecological principles to food and farming systems. Simultaneously a science, a set of practices, and a social movement, it centres on equitable and sustainable food and fibre production, processing, distribution, and consumption.

Historically, agroecology is associated with a multifaceted body of transdisciplinary knowledge. The academic literature emphasizes the role of scientists in developing an interdisciplinary agroecology over the past 90 years. However, the practice of agroecology is much older, with deep roots in many indigenous and peasant societies of Africa, the Americas, Asia, Australia, Europe, and Polynesia. Although these societies never adopted the term “agroecology”, their time-tested practices in growing food and fibre illustrate many principles of modern agroecology.
Today the idea and transformative promises of agroecological practices constitute an alternative to the 4th industrial revolution… Agroecology or chaos.
