description Publicationkeyboard_double_arrow_right Article , Journal 2020 BrazilPublisher:Springer Science and Business Media LLC Authors: Isamara Sousa Conceição de Benathar; Bruna Virgílio Almeida; Marcos Rodrigues; Jonathan Benathar de Oliveira Sousa; +3 AuthorsIsamara Sousa Conceição de Benathar; Bruna Virgílio Almeida; Marcos Rodrigues; Jonathan Benathar de Oliveira Sousa; Marcel Regis Moreira da Costa Machado; Ângelo Augusto Ebling; Selma Lopes Goulart;Copaifera oleoresin is an important traditional non-timber forest product in the Amazon; however, the Carajas National Forest has no plans to harvest this product to benefit extractive families. The objective of this study was to determine Copaifera oleoresin extraction potential in the Carajas National Forest, Eastern Amazon, identifying variables that could increase the chances of finding oleoresin. We mapped 129 trees and formulated a multiple logistic regression model (logit) with the collected variables: diameter at breast height (DBH), tree crown, tree health, presence of termites, and presence of damage or bifurcation. Among the mapped trees, we perforated 50 trees to harvest the oleoresin. Most of the oleoresin production occurred in trees with a DBH between 50 and 75 cm. The logit model predicted that an increase in DBH, dense crown, unhollowed trunk, and presence of damage or bifurcation increased the chances of oleoresin extraction, whereas termites did not. The model could contribute to the sustainable management of forest resources by avoiding random perforation of trees and establishing rational routes and cycles of extraction. Since the variables are easily measured, the model can be continuously used for future extractions.

O Programa Nacional de Produção e Uso do Biodiesel (PNPB) objetivou integrar agricultores familiares como fornecedores de matéria-prima para as indústrias de biodiesel, reduzindo assim a pobreza e promovendo o desenvolvimento rural. A integração de agricultores familiares foi revista devido a predominância da soja na cadeia de produção do biodiesel. Este estudo teve como objetivo comparar os mecanismos institucionais desenvolvidos por agricultores familiares e agentes econômicos em Mato Grosso a partir de dois diferentes estudos que ocorreram entre 2011 e 2013. O contexto teórico da Nova Economia Institucional foi necessário para identificar os mecanismos contratuais e de mercado desenvolvidos – arrendamento de maquinário, adicional de preço, fontes de financiamento e os pacotes tecnológicos – para aumentar a renda familiar e contribuir para o sucesso do PNPB em Mato Grosso. A presença destes mecanismos em diferentes regiões indica a difusão do conhecimento na rede produtiva da soja.
