La localidad escogida para este estudio de caso fue la comunidad indigena Guarani Yvyty, situada en la Ilha do Cardoso, municipio de Cananeia, Sao Paulo, Brasil. En la descripcion fueron enfocados algunos aspectos acerca del manejo agricola Guarani que estarian relacionados con la conservacion in situ del maiz (Zea mays L.) por ellos cultivado, el avaxi etei. Los datos de campo fueron recogidos a traves de los metodos comunmente utilizados en las ciencias sociales, tales como observaciones sistematicas y entrevistas con informantes \"claves\", utilizandose una guia semiestructurada para las cuestiones a ser investigadas. Los datos analizados muestran que la conservacion in situ de los cultivos del maiz avaxi etei presentes en las areas de tala y quema de las familias Mbya es posibilitada por los diversos mecanismos que componen su sistema agricola y que favorecen la manutencion y el aumento de la variabilidad genetica de sus cultivos. Entre estos mecanismos se destaca la constante practica de cultivos posibilitada por las redes de relaciones sociales entre las familias Mbya.","PeriodicalId":13651,"journal":{"name":"Interciencia","volume":"81 1","pages":"143-150"},"PeriodicalIF":0.4,"publicationDate":"2001-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64798109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
