El cultivo de maguey pulquero: opción para el desarrollo de comunidades rurales del altiplano mexicano Alberto Ulises Narváez Suárez Tomás Martínez Saldaña Mercedes A. Jiménez Velázquez Agrociencias Maguey biotecnología sustentabilidad desarrollo rural México es considerado centro de origen del género Agave, existen más de 200 especies, la mayoría endémicas del mismo país. Dentro de éstas, destaca el maguey pulquero (Agave spp.), el cual se adapta a condiciones de baja precipitación, heladas frecuentes y suelos infértiles que se presentan en amplias zonas del altiplano mexicano. Se realizó una investigación de tipo mixto conjuntando métodos cuantitativos y cualitativos. Se recorrieron diferentes municipios con tradición pulquera de los estados de Hidalgo, Tlaxcala, México, Puebla y Veracruz. Se aplicaron técnicas de investigación social a través de observación participante, entrevistas abiertas, el método etnográfico y una encuesta. Se analizó si el aprovechamiento del maguey pulquero es una opción viable que pueda contribuir al desarrollo de las comunidades rurales. Se concluye que la producción de maguey proporciona múltiples servicios ambientales y si se aprovecha de manera integral, con la técnica adecuada, buscando los canales de comercialización apropiados es recomendable y puede contribuir a detonar el desarrollo sustentable de las comunidades rurales del altiplano central mexicano. 2016 artículo científico 0186-4394 https://www.redalyc.org/articulo.oa?id=75749287005 es http://www.redalyc.org/revista.oa?id=757 Revista de Geografía Agrícola application/pdf Universidad Autónoma Chapingo Revista de Geografía Agrícola (México) Num.56
