Impactos de la redefinición del concepto de Trafkintü sobre la diversidad de variedades de quínoa cultivadas por agricultores mapuches en cuatro comunas de la región de la Araucanía del sur de Chile

Quínoa (Chenopodium quinoa Willd.) is a crop that is distributed from Colombia to the south of Chile. His early presence in the Mapuche territory is described from the first moments that the white man income to the territory. The seed exchange systems represent one of the principal accesses to the seed for the Mapuche people. The aim of this study is to analyze the impacts of the forms of exchange (trafkintu) on the diversity of varieties by Mapuche farmers n the Araucania region. By means of a qualitative research developed across constructed and semi-constructed interview in Mapuche communities. A result identifies two modalities of seed exchange: (a) A public exchange that assembles farmers from diverse localities to exchange their seeds. (B) A traditional exchanges among neighbors or inside the widespread family. The majority of the interviewed peasants realize both modalities of exchange. The reactivation of the seeds flow across the seeds exchange or Trafkintu as public event, it has allowed to strengthen a spread and social practice that allows to generate an amplifier for the local agrobiodiversity and to allow spaces of agriculture knowledge exchange.
