Ecological crisis in agriculture is linked to monologic power relations that developed around industrial productivist farming practices and masculinist scientific knowledge. In identifying and deconstructing the seminal figure of the modest witness in science, and applying it in the context of agriculture as a scientific practice, it becomes possible to locate social relations in agriculture where the farmer is a situated knower, who witnesses in relational and situated fields of practice. This approach attempts to move the study of masculinity in the rural and the agricultural from a masculine subject depicted in binary opposites of hegemony and subordination derived from discourses that give agency only to humans and particularly to men with certain traits. Taking masculinity as a conceptual tool and applying it in a context of sustainability, this article draws on ethnographic fieldwork to reveal examples of farming practices and their masculinities in relations that promise to restore local ecologies and economies.
