We will always remember Rodrigo’s humanistic spirit. (R. I. P.)

Javier Ignacio Martínez Sánchez

Since 1998 his research contributes to the reflection on the importance of the conservation of the symbolic territories of the Wixárika People (huichol) in Mexico, for the preservation and respect of their pre-Columbian custom. This through his studies in Agroecology and master’s degree in Social Anthropology in a portion of the northern region of the state of San Luis Potosí, called “Wirikuta” in the municipality of Catorce. Particularly it focuses on the problem arising from the restrictive framework that surrounds the consumption of peyote (lophophora williamsii) in our country and Wirikuta in particular, the events that occur there involve or define contradictory and tense relationships at various levels between authorities, indigenous and non-indigenous users, and people who live in the places where the sacred plant is collected. In his study, attempts are made to recover the conflicting aspects of the social process that are deflated from a series of efforts and proposals to conserve peyote, widely used by non-indigenous people. Of all this, this study highlights the enormous distance between a backward and inoperative legal framework and the heterogeneous and complex social dynamics of ceremonial use of peyote in Mexico.

After this period, Javier works for the federal government implementing support from the National Forestry Commission in the Potosino Altiplano region, managing to insert support for restoration practices in areas degraded by overgrazing. He currently coordinates at Nierika A.C. things concerning the conservation strategies of the territories and the practices of Mexican traditions regarding the ceremonial use of Peyote. Since 2016 he represents Nierika AC, forming part of an international indigenous initiative for the conservation of Peyote in America (IPCI).”
