17. Os conhecimentos tradicionais Paĩ Tavyterã, Kaiowá e Guarani sobre o ka’a he’ẽ (Stevia rebaudiana)

Author

Felipe Vianna M. Almeida and Marcos Glauser Ortiz

Abstract

Este artigo descreve os conhecimentos tradicionais relacionados ao uso e manejo da Stevia rebaudiana pelos Paĩ Tavyterã, habitantes do departamento de Amambay, no leste do Paraguai, e dos Kaiowa e Guarani, do sul do estado brasileiro do Mato Grosso do Sul. Esses indígenas, conhecem essa planta pela denominação ka’a he’ẽ, em guarani. Por meio da realização de duas pesquisas interculturais, realizadas no Brasil e Paraguai, são descritos os usos relatados por anciões e anciãs com o ka’a he’ẽ, incluindo conhecimentos ecológicos e o manejo da planta. O ka’a he’ẽ, além de ser utilizado como um remédio para a cura de vários males, e como um edulcorante de alimentos, era consumido por jovens, mulheres e homens, na fase de transição para a idade adulta, momento no qual seus corpos se tornavam especialmente vulneráveis a influências externas. Nesse contexto, o consumo de folhas de ka’a he’ẽ, e a aplicação de infusão das folhas em partes do corpo, contribuía com a capacidade de produzir ou extrair alimentos doces, tal como o kaguĩ (chicha) doce, pelas mulheres. Além de produzir a capacidade de tornar algo doce, o ka’a he’ẽ atuava de forma protetiva, moderando e controlando os poderes de alteração dos corpos dos jovens durante a fase de jekoaku na transição para a fase adulta, espantando seres cujas afecções ao corpo não são desejadas. A planta era usada em especial no ritual do kunumi pepy, logo antes da furação dos lábios inferiores dos meninos para a inserção do tembetá.

Abstract

Brazil is one of the largest exporters of cattle meat production. Most of this production is under pasture areas, with different levels of livestock and field management. Remotely sensed images could be interesting tools to detect distinct temporal and spatial patterns of these systems. In this context, classification algorithms have been proposed to use information from satellite images to map different land covers. The Time-Weighted Dynamic Time Warping (TWDTW) is an algorithm that has the advantage of working well with datasets with enough amounts of temporal information and seasonality patterns. In the present work, the TWDTW was performed to classify pasture managements in farms located in Western region of São Paulo State in Brazil for the years 2017 and 2018, as a primary study. It was used Normalized Difference Vegetation Index (NDVI) time series images from Moderate Resolution Imaging Spectroradiometer – MODIS sensor (products MOD13Q1 and MYD13Q) with 250 meters of spatial resolution. In classifications for the years 2017 and 2018, it was observed a predominance of traditional pasture. Total areas of degraded and traditional pasture were very similar between 2017 and 2018. The year of 2017 showed higher spatial distribution of intensified pastures than year 2018. The classification achieved satisfying results with complete accuracy in validation. The information collected from field visits were important to analyse general aspects of the results. Therefore, in this pilot study TWDTW algorithm demonstrated to have potential in differentiating classes of pasture management. Next steps will be to explore the possibilities to classify pasture systems in large areas.
