Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA) showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6) t) to 2008 (2.05 10(6) t) was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ) when compared to the "not from concentrated" juice (NFC). Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

O agronegócio é uma das principais atividades da economia no Brasil e de suma importância para a balança comercial brasileira. Neste cenário a exportação de grãos coloca o Brasil em uma posição privilegiada no comércio internacional de commodities agrícolas. Em 2017 o milho foi o principal responsável pela alta performance do setor, com o crescimento de 13%. O grão protagonizou no ano de 2017 a produção de 97 milhões (t). O objetivo deste artigo é investigar eventuais gargalos logísticos na operação de recebimento e armazenamento do milho no complexo portuário de Santos. Para tanto, optou-se por estudar os referidos processos em um terminal portuário de exportação, aqui denominado Terminal A utilizando-se de simulação. Os resultados apresentam duas operações distintas, a chegada do grão no terminal por ferrovia (vagão) e a chegada por rodovia (caminhão) e apontam potenciais gargalos operacionais.

Competitiveness of Brazilian agribusiness depends on the capacity to sell products through the largest port in South America, Santos. The aim of this paper is to analyze the port efficiency indicators of Brazilian National Waterways Transportation Agency regarding the Port of Santos. To this end, we collected the indicator of port for handling, service time, and tariffs (fee) during of period of 2016-2018 and analyzed using time series. The results showed a tendency of slight growth for handling, moderate growth for the tariff, and a slight decrease in the service time.
