A traves de una descripcion estricta fue analizado el sistema agricola practicado por algunas familias de la etnia Guarani Mbya que habitan la region Sudeste del Brasil. 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.
本文分析了巴西东南部瓜拉尼姆比亚族的一些家庭所实行的农业制度。本案例研究选择的地点是位于巴西圣保罗Cananeia市Ilha do Cardoso的Guarani Yvyty土著社区。在描述中，重点介绍了瓜拉尼农业管理的一些方面，这些方面与他们种植的玉米(Zea mays L.)的就地保护有关，avaxi etei。本研究的目的是通过对社会科学中使用的方法的研究，如系统观察和对“关键”线人的访谈，以及对要调查的问题的半结构化指南来收集实地数据。数据分析表明,就地基姆的玉米作物avaxi etei参加Mbya areas家庭和燃烧的是海产品agricola系统组成的各种机制有利于manutencion增加作物的基因变异。在这些机制中，值得注意的是Mbya家庭之间的社会关系网络使不断的农业实践成为可能。

In this age of modern era, the use of internet must be maximized. Yeah, internet will help us very much not only for important thing but also for daily activities. Many people now, from any level can use internet. The sources of internet connection can also be enjoyed in many places. As one of the benefits is to get the on-line efficient use of energy book, as the world window, as many people suggest.
