O conceito de falha metabólica em articulação com a perspectiva agroecológica e da sustentabilidade: contribuições ao ensino de ciências

Abstract

The present work refers to investigative studies of a theoretical nature, with bibliographical and documentary analysis, involving possible articulations between the Teaching of Sciences (of Nature (SN) and Agrarian) and the agroecological and sustainability perspective, from a concept proposed by us as structurally called “Metabolic Failure” (MF). Karl Marx, originally developed this concept when analyzing the privatization and exploitation of land (a common good) whose appropriation of its nutrients and plant organisms for exchange purposes produces, intensifies and accelerates the inexorable irreversibility of replacement of these. It produces and intensifies irreversibly, therefore, both MF and the possibility of achieving sustainability (environmental). To this end, we discourse the origin, formation, composition, management and use of soils as fundamental elements in search of restoring greater unity between human beings and nature, besides helping to a better understanding of the contradictions arising from agricultural production dependent on artificial inputs. We seek to argue that agroecological science can contribute to the understanding (and minimization) of the set of deleterious effects that cause exacerbation of MF and the disturbances around the relationship between human beings and nature, especially when agroecological practices and studies establish dialogues with postulates and concepts concerning the sciences of nature. We argue favorably that this perspective can also feedback the formative processes in agroecology, based on the mediations built around an interdisciplinary proposal and sustainability. Finally, we seek to maintain that the concept of MF mobilizes, highlights, problematizes and articulates a set of themes and concepts of the areas of Sciences Nature (SN) and agroecology, which, aided by the “Unifying Concepts”, aim at a restructuring of thinking about sustainability committed to education and training in agroecology.
