Frédérique Apffel-Marglin, PhD. is Professor Emerita, Dpt. of Anthropology at Smith College and founded Sachamama Center for Biocultural Regeneration in the Peruvian Upper Amazon in 2009 which she directs. She has spent years in India and Peru working with indigenous peoples and with farmers. She was a research associate at the World Institute for Development Economics Research (WIDER) in Helsinki, a part of the United Nations University, for several years in the 1980’s and early 1990’s. Along with the Harvard economist Stephen A. Marglin, she has directed several research projects questioning the dominance of the modern paradigm of knowledge. She has authored as well as edited fifteen books and published over 60 articles. In 1993 she decided for political and ethical reasons that she could no longer engage in classical anthropological fieldwork and ever since then has been invited to collaborate with activist/intellectual groups in Peru and Bolivia. A recent book is Subversive Spiritualities: How Rituals Enact the World (oxford U. Pr. 2011) A more recent book about her work in her center in the Peruvian Upper Amazon is written with Robert Tindall and David Shearer: Sacred Soil: Biochar and the Regeneration of the Earth; North Atlantic Books, 2017. A Spanish translation has been published by Apus Graph in Lima in 2019 titled: “Yana Allpa; Biocarbon; una Solucion Amazonica a la Crisis Climatica”.
