Relationships between Land-Use Types and Plant Species Used by Traditional Ethno-Medical System

Abstract

Aims:The agricultural frontier advances progressively on forested regions in Central Argentina, changing the landscape structure by extremely reducing the extension of native forests. In rural communities that are related to the forests, it is possible that severe changes in the landscapes can have an impact on the knowledge and uses of medicinal plants. The aim of this paper was to evidence some general patterns between the ethnobotanical information recorded in the Chaco region and some characteristics of the landscape. Specifically, we hypothesized that the knowledge on medicinal plants and their type (native or exotic) are related to different types of land use (i.e. different proportions of native forests). Place and Duration of Study:The study was performed 15 rural localities within the Chaco phytogeographic regionin Córdoba, Argentina, conducted between 2004 and 2012. Methodology: A total of 279 interviews were conducted. Plant species were identified according to their status (native or exotic), and a standardized proportion of exotic

Prácticas tradicionales de manejo de recursos vegetales en unidades de paisajes culturales del oeste de la provincia de Córdoba, Argentina

“…De manera similar se ha documentado este patrón de uso de recursos vegetales en el semiárido de Pernambuco (Teixeira do Nascimiento et al, 2007) donde se documentan usos asociados a guardar el ganado, proteger y limitar los hogares, pero siempre con un patrón generalizado en todos los casos en que los pobladores realizan modificaciones al paisaje original en medianas porciones de terrenos cercanos al hogar, para satisfacer sus necesidades El "monte" como sitio natural o menos modificado por el hombre presenta características que lo distinguen como la presencia casi exclusivas de especies nativas y como sitio de recolección de plantas medicinales, alimenticias y forrajeras. En la Provincia de Córdoba, Arias Toledo et al ( ,2014) mencionan a las zonas boscosas en distinto grado de conservación como espacios casi exclusivos de acceso a plantas medicinales, mientras que el acceso de plantas alimenticias Arias se realiza cuando los hombres realizan trabajan en el monte, momento en el que consumen frutos. Por otro lado, en relación a las especies forrajeras, Trillo et al (2014) presentan las mismas especies que este estudio y similares estrategias de recolección de dichas especies.…”

Soil, Seeds, and Roses: Plantation Afterlives in an Argentine Soybean Frontier

“…In turn, Marta worried that agrochemical toxicity and lack of pasture had left farmers with "no more animals." This wide-ranging absence spanned insects in the soil, backyard animals like Marta's hens, fish from vanishing or intoxicated streams and wild game from the bushlandsincluding numerous endangered species (such as peccaries and armadillos) traditionally used as food or medicine by local Chaco peoples (Arias Toledo et al 2014;Martínez 2013). 11 Marta was preoccupied by the dwindling small-scale cattle industryalso a driver of Chaco deforestation over timethat she feared was now being overtaken by sojización (literally, "soyification") and large-scale feedlot cattle farming.…”

Exotic and native species used by traditional populations of the Patagonian steppe: An approach based on redundancy and versatility

“…Despite overgrazing of the land, native plants are the most predominant species in the region, and local communities have learned throughout their history to use them in a sustainable way (Castillo et al, 2020). Other studies carried out with traditional communities in Argentina have shown that there is a strong relationship between the conservation status of the native environment and the proportion of native species used by local populations (Arias Toledo et al, 2010Toledo et al, , 2014.…”
