Pathways as "signatures in landscape": towards an ethnography of mobility among the Mbya-Guaraní (Northeastern Argentina).

Processes of spatial mobility among the Mbya are of interest in anthropological and ethnobiological studies, as these processes are related to transformations in the landscape and the environment. Despite this, ethnographic literature usually focuses itself on the mobility of Guaraní communities from the perspective of population dynamics on a regional scale. Our research among two Mbya-Guaraní communities in the Argentinean province of Misiones has enabled us to recognize patterns of mobility on a micro-scale.

Environment and illness in the Calchaquí Valley (Salta, Argentina): phytotherapy for osteo-articular and cardio-circulatory diseases.

The aim of this work is to analyze and discuss the phytotherapy employed for two kinds of diseases, osteo-articular and cardio-circulatory, among the inhabitants of Molinos (Calchaquí Valley, Salta Province, Northwestern Argentina). These diseases take their origin in certain environmental conditions as well as the rural activities characteristic of the zone. The observations and interviews conducted among "medicos campesinos" (traditional healers) and the general population provided valuable information concerning the relationship between man and his environment, as it relates to health-illness processes.
