Genes in the Chagra: Crop and Crop Wild Relative Landesque Capital among Amazonian Runa in Ecuador

Abstract

This study delves into the relationship between human cultures and plant genetic diversity, centering on the expanded concept of landesque capital. Traditionally, this term has encapsulated human-made environmental modifications, such as anthropogenic soils or terraces, that can yield long-term benefits. We extend this notion to embrace the genetic diversity and dynamics of crops and crop wild relative (CWR) gene pools. The investigation focuses on the Napo Runa of Ecuador and their cultural practices, including selection, seed saving, and transplantation, to highlight potential models of selection pressures affecting crop-CWR complexes and any cultural practices connected to either. In doing so, we aim to underscore the interconnected and multispecies nature of the relationships among genetic diversity and cultural diversity. Changes in the genetic makeup of one plant, induced by human interaction, can affect its cultivated counterparts through hybridization or future breeding programs, thereby influencing agricultural resilience, nutritional value, and the very cultural practices dependent on these crops or any related to them. Consequently, we argue for a focused examination of plant-based forms of landesque capital or any gene pool-based form, including animals or microbial life. This approach highlights the importance of interconnecting biocultural diversity between cultivated plants and their “wild” relatives and recognizing the intricate interdependencies between cultural practices and gene pools in the face of environmental challenges.
