This new global era demands the reformulation of the old paradigms of the "green revolution" and the industrial agricultural model of the 20th century. The strong incidence of intensive agro-industrial processes, from systemic agrochemicals and the energy required to produce ultra-processed products offered to society as food, are changing the way food systems function and, in many cases, in ways that are far away from the sustainability of ecosystems.

This book brings together the results of research projects carried out thanks to the support of the alliance of the McKnight Foundation and the Latin American Council of Social Sciences (CLACSO) in the "Research and Training Program in Andean Agroecological Systems". Through the study of small-scale agriculture in local communities in the highlands of Ecuador, Peru and Bolivia, its chapters explore how agroecology as a science, practice and movement contributes to the construction of a new food model, with the expectation to achieve the positioning of agroecology in the Andean's political and academic agenda.
