Are we on the verge of a fourth agricultural revolution?

Are we on the verge of a fourth agricultural revolution? In this insightful analysis, Professor Guillaume Blanchet from Université de Sherbrooke examines whether we are on the verge of a fourth agricultural revolution and explores new technologies for agroecology. The first agricultural revolution is considered to have occurred sometime ten to twelve thousand years ago when humans transitioned from being hunters and gatherers to settlements focused on agriculture. The second agricultural revolution was between the 17th and 19th centuries when new technologies (such as crop rotation, drainage and plough) were developed, significantly increasing yield and productivity.
