Este artículo examina la relación entre los conocimientos y la preservaciónde la agrobiodiversidad de agricultores ecológicos del oeste de Santa Catarina, Brasil. Los derechos de propiedad intelectual han tenido efectos directos sobre la producción de semillas. Entre patentes y otras formas de controles, agricultores familiares y actores conexos no aceptan tratar la vida como un «recurso». Este trabajo tiene un doble objetivo: primero, analizar el panorama internacional de la propiedad intelectual sobre la biodiversidad y la producción de conocimientos, y segundo, examinar las acciones de agricultores vinculados con Ecovida —red de agroecología compuesta por agricultores, consumidores y mediadores sociales en el sur del Brasil— para inventar formas alternativas de gestión de los saberes y de semillas «libres». El resultado es una acción paralela de crítica al estrechamiento de la base genética y un esfuerzo por la multiplicación de semillas y saberes por medio de redes y centros de agrobiodiversidad. / The article approaches knowledges and biodiversity maintenance among ecological farmers in the west of Santa Catarina state, Brazil. The intellectual property rights have had direct effects onseed production. Between patents and other systems of control, family farmers deny treating life as a «resource». This paper has adouble aim: firstly, to analyze the intellectual property international panorama over biodiversity and knowledge; secondly, to examine practices of organic smallholders engaged to Rede Ecovida de Agroecologia (an organic farming network born in the southern Brazil) related to alternative forms of knowledge management and production of patent-free seeds. The result is the action which parallels the critique of the decrease on the availability of crop varieties and the effort to multiply seeds and knowledges throughout networks and agro-biodiversity centres.
