“…All the indigenous communities that participated in this research project have access to highly weathered soils and alluvial soils for manioc production [60][61][62]. Highly weathered soils classified as Oxisols and Ultisols [63] are acid (pH 3-5.5) soils, characterized by prolonged periods of weathering and leaching during their formation, resulting in soils with a low cation exchange capacity, limited amounts of cations and a very low phosphorous availability.…”

Abstract:Manioc is an important root crop in the tropics and the most important staple food in the Amazon. Manioc is diverse but its diversity has not yet been clearly associated with environmental or social factors. Our study evaluates how variation in edaphic environments and in social factors influences manioc diversity among five ethnic groups of the Amazon region of Colombia. Inventories of landraces, genetic analysis of manioc diversity, visits to farmers' swiddens and interviews with farmers were carried out during two years of field work. Morphotypic and genotypic diversity of manioc were large. The different ethnic groups of our study cultivate different sweet and bitter manioc landraces which they select and maintain in accordance with their ancestral rules and norms. Differences in available environments among indigenous communities (such as the presence of different soils) did not markedly affect manioc morphotypic or genotypic diversity, while social factors considerably influenced observed manioc diversity. Manioc diversity was explained by two parallel processes of manioc diversification: volunteer seedling selection and manioc seed OPEN ACCESS Diversity 2014, 6 793 exchange. We argue that, for a full understanding of manioc diversity, indigenous knowledge, as well as morphological and genetic variation should be taken into account.

This paper aims to survey ethnoagricultural knowledge by a community living in an area of Atlantic tropical rainforest in Brazil. Interviews were conducted to 20 persons who are still related to the use of plants. All of them had cultivated roças in the past, activity they reported to have abandoned due to changes in environmental law, tourism activities and lack of land for planting. There is still a rich ethnoagricultural memory based on the traditional practices of cultivation of plants, management of the land, and the observation of nature. However, this knowledge is rapidly disappearing albeit its high socioenvironmental value and its recognized tangible and intangible biocultural heritage.

“…Esta nova fonte de alimentos pode ser uma contribuição positiva, pois se torna importante fonte de cálcio e proteínas, e é destinada aos indivíduos de faixa etária em que as mudanças são mais perceptíveis. Adams et al [20] identificaram entre populações ribeirinhas, que a merenda escolar constituía parte importante da alimentação das crianças.…”

ResumoO objetivo deste trabalho foi analisar as transformações ocorridas na alimentação da comunidade indígena xavante, da aldeia Wede´rã, no Estado de Mato Grosso, Brasil, com a introdução da agricultura mecanizada. Foi utilizado o enfoque qualitativo, com técnicas de entrevista e observação participante. Verificou-se que, com a introdução da mecanização na produção agrícola e o processo de sedentarização, o arroz tornou-se base da alimentação, substituindo outros alimentos tradicionalmente consumidos, obtidos principalmente através da coleta. A utilização da caça ainda permanece, entretanto, com maior impacto ambiental. Outras alterações na dieta são a compra de alimentos industrializados e a composição das refeições do Programa Nacional de Alimentação Escolar -PNAE, popularmente conhecido como merenda escolar. Tais transformações podem estar associadas à causa de 56,3% de prevalência de anemia entre a população da aldeia, constatada em 2006. Há esforços para alterar esse quadro, mas, mudanças no modo de vida e organização social dos indivíduos e nas relações destes com a natureza, podem estar comprometendo a sua segurança alimentar e nutricional de modo irreversível.Palavras-chave: estratégias de subsistência; Jê; Hábito alimentar; Sociedade de caçadores-coletores; Segurança alimentar. Changes in Subsistence Strategies: The Case of the Xavante Brazilian Indians AbstractThe work aims to study the changes in food habit among the Xavante's (a brazilian Indians tribe) living in Wede'rã village, part of Pimentel Barbosa Reserve in the Mato Grasso State, in Brazil. Through personal interviews and participant observations we could see that food production mechanization, instead fruits and vegetable gathering, have increased the white rice consumption and have caused the abandon of nomadic practices, bringing bad consequences for health. Hunting is still practiced, but also is having ecological negative effects. Together with the increasing use of industrialized food, as in the school lunches, these changes in food consumption are associated with higher (56.3% in 2006) anemia rates. There are some efforts in order to revert present situation, but changes in their life style, in their social organization, in their social organization and in their relationship with their environment is an irreversible threat to their food and nutritional security.
