Rede de trocas de sementes e conservação da agrobiodiversidade: um estudo em comunidades tradicionais quilombolas no município de Mariana, Minas Gerais

Abstract

The creation of agrobiodiversity by humans and nature together forms a system of socio-ecological interdependence. Ethnovarieties are created and circulated through well-liked methods of genetic improvement, being selected, duplicated, and continuously modified. In this regard, the goal of the current effort is to assess the contribution that seed exchange networks provide to the "onfarm" preservation of agrobiodiversity associated with food. We postulate that the seed exchange network's organizational makeup determines how well it can preserve agrobiodiversity. Data was collected using ethnobotany methods, and socioecological network metrics were employed for analysis. We spoke with 48 partners who were residents of Mariana's quilombola settlements; 359 ethnovarieties were trademarked and belonged to 134 species in 44 botanical families. Our open network includes 185 family units and organizations that manage agrobiodiversity. The amount of managed agro-environments and total cultivated land are elements that affect the diversity of ethno-varieties that farmers are familiar with, along with time spent in the community. The findings demonstrated a favorable correlation between socioagronomic variables and the diversity of ethnovarieties and the centrality of degree, intermediation, and harmonic closeness of farmers. In terms of topology, we got a network with a lot of modularity, little nesting, and little connectedness. proving that the distribution of ethnovarieties is not equitable since it transcends the boundaries between the social standing of the management units and the biocultural worth of the plants. Promoting group tactics that support the preservation of agrobiodiversity on farms is essential in this approach.
