This work presents the cashew nuts chain in the State of Rio Grande do Norte between 1960 and 2009. The main purpose of this research was to find the reason of the low productivity of the cashew nut in this state, identifying in the cashew's chain production the struggling points which were limiting the commerce of this product through the distribution network. Therefore, the Supply Chain Management was used as a logistic analysis methodology, focusing on relationships management between the nodes of this chain, from the producer until the final customer. Many problems were found: first, the precarious production conditions of the small producer don't lead to reach the demanded productivity by the market. The distance, the lack of communication of the small producers among themselves and an archaic way of dealing with their businesses, may be an explanatory reason for this problem, considering that those factors are the main elements which contribute for the weakening of the small producer placed in the productive chain. Another spotted point was that the business-oriented relationship between the producer and the local trader does not allow the small producer's economical development, which interferes in any technological investment to reach a good quality production that fulfills the market demand. And also, the fact that there is a tendency of the final costumer to require lower prices day-byday, forcing a pressure on the nodes transferring to the other and successively until arriving at the producer who inevitably is suffering the biggest impacts from this mentioned pressure.

This research aims to study the manioc flour productive chain in order to understand how the relationship between its segments happens, specially between the flour agroindustry and the distribuition. This research was made from a study of case that envolved three agro industries from the Potiguar wasteland and a company of food distribution. The filiére and the supply chain management analysis were applied to identify the functioning and the organization of the manioc flour productive chain. From the study of case it s noticed that the existing contracts, even the informal ones, has mutual benefits and it suggests that they be legalized

A região do Alto Tietê é responsável por 85% da produção de nêspera do Estado de São Paulo. Atividade rentável, nos últimos anos os produtores verificaram uma queda na sua lucratividade. Este trabalho teve como objetivos sistematizar informações econômicas sobre a cadeia produtiva e analisar a estrutura de mercado. A evolução dos preços da nêspera mostra crescimento até o ano 2000 e posterior queda. O mercado atacadista tem atuado como um colchão amortecedor. O maior desafio para os produtores de nêspera se encontra no âmbito organizacional. A estrutura de mercado e os resultados da pesquisa de campo indicam que os produtores do Alto Tietê encontram-se em posição vantajosa para um reposicionamento nesse aspecto, importante para uma participação sustentável na atividade.

The paper demonstrates how it is organized production chain of natural gas in Rio Grande do Norte and highlights some prospects for this sector. The study is backed by elements to understand the process of innovation as the driving force of capitalist dynamics as well as the features of the Brazilian economy in the years 1990 and 2000 that indicated the development of natural gas production in the energy matrix Brazil. It was found that the state has potiguar possibilities for structuring an energy based on elements from the region and with prospects of becoming self-sufficient in electricity, where natural gas has a share of participation in this segment. The automotive and industrial are the biggest consumers of this input. With emphasis on the textile industry. Signaling to a broad horizon of supply, this sector will depend on their investments in research and Deficient, and the policy adopted by government to develop the consumer market

The Agroindustrial System coffee after decades of state regulation has become a decentralized economic activity. This situation compelled most of the actors in the production chain to resort to self r egulatory systems offered by certification agencies, which have specific criteria and procedures. However the diversity criteria of the agencies do not offer resources able to ensure efficient management of the governance structure. There is a need to reduce the asymmetry of information, which is possible through the sharing of data compatible with the production tracking feature. This work is supported in this contextualized problem, based on Transaction Cost Theory and the use of qualitative and quantitative research methodologies. The first part of the work seeks to know the procedures required by leading regulatory agencies in Brazil, with perspective to emphasize the similarities and compatibilities between them, which was reached after analysis of standards and comparison of similarities. Next is registered the operation and the coffee traceability of the structure, in order to identify, through observation, documental and bibliographical analysis, the systems in place and traceable information in line with the recommendations of the coffee certification. Finally, he sought to create a labeling model that allows to generate and share information about the product from the field to the sale for consumption. The information obtained in the previous steps were the basis for data collection with the production chain agents through a structured questionnaire administered to 618 agents of the production chain, whose answers were treated by multivariate methods of statistical analysis. The results showed that actors in the chain are in favor of inclusion and sharing information related to rural production and economic and environmental data. This knowledge enabled develop a labeling model where the information sharing agents is an efficient mechanism to mitigate the governance problems identified.

O presente trabalho monitorou a saúde de oito espécies de acaris ornamentais capturados e comercializados no Médio Rio Guamá - Pará, através do estabelecimento do quadro hematológico basal, avaliação de estresse de transporte e de infecção por Trypanosoma spp. São elas: ancistrus (Ancistrus sp. - L338), loricaia (Rineloricaia lanceolata - L10), picoto (Hypostomus sp. - L28), bola (Peckoltia oligospila - L06), pleco (Cochilodon sp. - L145), canoa (Lasiancistrus saetiger - L323), assacu (Pseudacanthicus spinosus - L160) e pinima (Leporacanthicus galaxias - L07). As coletas sanguíneas para a determinação do quadro hematológico basal (Capítulos I e II) foram realizadas ainda no local da captura dos peixes, sob o mínimo de estresse possível. Separarou-se as amostras sanguíneas não infectadas para possibilitar comparações com as do após-estresse de transporte (Capítulos III e IV) e também com as infectados por Trypanosoma spp. (Capítulo V). O estresse de transporte estabelecido durou 3h, com densidade de 1,5 peixe/L, simulando o processo de comercialização dos peixes na região e foi avaliado após 0, 6, 24, 48, 72 e 96h. Nos Capítulos I e II, observou-se que o hemograma basal apresentou diferença significativa (p>0,05) entre os as sete espécies de acaris, apesar de estas pertencerem a mesma família e compartilharem nichos ecológicos semelhantes. O estresse de transporte por 3h (Capítulos III e IV) não comprometeu a saúde dos acaris, pois a maioria dos parâmetros hematológicos retornou aos níveis basais em 24h em bola, em 48h em pleco e em 72h em picoto, sendo estes, respectivamente, os períodos mínimos indicados para a aclimatação destes peixes antes de uma nova comercialização. Todas as oito espécies de acaris estudadas estavam infectadas por Tryopanosoma spp. (Capítulo V). Encontrou-se anemia normocítica-hipocrômica em ancistrus e canoa, e anemia macrocítica-hipocrômica em loricaia. Pinimas infectados apresentaram quadro de estresse com linfocitopenia, neutrofilia e monocitose. Assim, os resultados deste ensaio proporcionaram a avaliação da higidez destas espécies de acaris ornamentais através de exames hematológicos, podendo assim subsidiar o desenvolvimento ou a adequação do manejo menos estressante para estes peixes, de forma a auxiliar a sustentabilidade da cadeia extrativista das espécies ornamentais.
