Artisanal extraction and traditional knowledge associated with medicinal use of Crabwood Oil (Carapa guianensis Aublet.) in a peri-urban Várzea environment in the Amazon Estuary.

Varzea forests of the Amazon estuary contain species of importance to riverine communities. For example, the oil extracted from the seeds of crabwood trees is traditionally used to combat various illnesses and as such artisanal extraction processes have been maintained. The objectives of this study were to (1) describe the process involved in artisanal extraction of crabwood oil in the Fazendinha ProtectedArea, in the state ofAmap´a; (2) characterise the processes of knowledge transfer associated with the extraction and use of crabwood oil within a peri-urban riverine community; and (3) discern medicinal uses of the oil.The data were obtained using semistructured interviews with 13 community members involved in crabwood oil extraction and via direct observation.The process of oil extraction is divided into four stages: seed collection; cooking and resting of the seeds; shelling of the seeds and dough preparation; and oil collection. Oil extraction is carried out within the home for personal use, with surplus marketed within the community. More than 90% of the members of the community involved in extraction of crabwood oil highlighted the use of the oil to combat inflammation of the throat. Knowledge transfer occurs via oral transmission and through direct observation.

Intercâmbio de experiências e levantamento de demandas ergonômicas em unidades de beneficiamento de frutos do cerrado, mandioca e café em comunidades do Norte de Minas Gerais.

Este relato descreve a experiência realizada por meio de uma parceria entre o Projeto Rio Pardo, da Embrapa Cerrados e a Escola Politécnica/USP, visando inserir a questão do trabalho agrícola familiar nas ações desenvolvidas junto aos agricultores de três comunidades de Rio Pardo de Minas/MG, produtoras de frutos do cerrado, goma/farinha de mandioca e café sombreado. O objetivo foi levantar possíveis demandas ergonômicas existentes nestas unidades de produção, que estão implantando agroindústrias familiares para realizar o beneficiamento da produção. As demandas relacionam-se a problemas com a produção, a organização do trabalho e a saúde dos trabalhadores. Percebe-se a coexistência do saber tradicional, transmitido entre gerações, com a inovação em termos de maquinário e instalações. Há diversos arranjos produtivos presentes, fruto da criatividade e sabedoria aplicada dos agricultores. Estas inovações podem ser o embrião de projetos futuros de novos maquinários e arranjos produtivos. Trata-se de fazer comunicar dois saberes, dos projetistas e dos usuários, contribuindo para que estes últimos possam ser empoderados no papel de criadores de inovações, contribuindo para a incorporação de aspectos ergonômicos na evolução dos equipamentos e instalações. Abstract: This report describes the experience carried out through a partnership between Project ? Rio Pardo ?, Embrapa Cerrados/DF and the Polytechnic School of USP, in order to put the issue of family farm labor in the actions developed by farmers in three communities of Rio Pardo de Minas, north of Minas Gerais. The main products are fruits of the cerrado, cassava starch and manioc flour and shaded coffee. The initial goal was to raise possible these existing ergonomic demands of family farming units, which are in the process of implementation of family agri-industries to undertake the processing and beneficiation production. The ergonomic demands are related to production problems with the organization of work and the health of farm workers. In preliminary analyzes, it was possible to perceive the coexistence of traditional knowledge transmitted between generations, with innovation in terms of machinery and facilities. There are several productive arrangements, result of creativity and knowledge of farmers. These innovations, developed by who performs the work, may be the starting point for future designs of new machinery and productive arrangements. It could demonstrated the importance of communication between two knowledge, from the designers and from the users (farmers), contributing to the latter to be empowered in their role as creators of innovation and contributing to the incorporation of ergonomic aspects in the context of setting up their equipment.

Creolo beans production systems in Juruá valley, Acre, Brazilian Amazon.

The Juruá valley mesoregion is recognized for its diversity of cultivars of common beans and cowpea and is an important center for on farm bean conservation in Brazil. However, there is little information about production systems of Creoles cultivars and, in this approach, the study aimed to identify the production centers and to gather information about beans production systems. Thirty eight farmers and five merchants were interviewed using semi-structured questionnaries. Juruá valley farmers use three beans production systems: "beach farming", "slash burn system" and "stuffy farming". The systems use family labor with low dependence on external inputs, two classified as itinerant. The study identified two beans production centers: Alto Juruá extractive reserve and Santa Luzia directed settlement project.
