Description
An account of the resource
Os quintais agroflorestais são comuns entre os agricultores familiares da Amazônia, sendo sistemas de uso da terra sustentáveis desenvolvidos a partir dos saberes tradicionais. Além de ter como principal finalidade a promoção da segurança alimentar, são espaços de socialização e lazer para os agricultores e, podem contribuir para a composição de sua renda pela venda do excedente da produção. O objetivo desse trabalho foi identificar a diversidade dos quintais, a partir da composição de flora e fauna. A pesquisa estudou 37 quintais agroflorestais em cinco comunidades em Igarapé-Açu e Marapanim, nordeste paraense, usando técnicas de observação direta em campo, aplicação de questionários semiestruturados, notas etnográficas e turnê guiada nos quintais agroflorestais. Foram 107 espécies vegetais identificadas e 12 animais. Estes dados revelam que há uma quantidade maior de espécies comparativamente a outros estudos, o que se pode inferir grande conhecimento tradicional empregado na constituição e diversificação desses sistemas de uso da terra no local de estudo, considerando, o baixo nível tecnológico e força de trabalho familiar empregados. Assim, esses espaços característicos das paisagens rurais dos agricultores familiares do nordeste paraense correspondem elementos fundamentais dos seus agroecossistemas, gerando produção e garantindo a reprodução das famílias.Floristic and faunal composition homegardens of family farming in northeast ParáAbstract: The homegardens are common among family farmers in the Amazon, and sustainable land use systems developed from traditional knowledge. Besides having as main purpose the promotion of food security, they are spaces for socialization and recreation for farmers and can contribute to the composition of its income from the sale of production surplus. The aim of this study was to identify the diversity of yards from the flora and fauna composition. The research studied 37 homegardens in five communities in Igarapé-Açu and Marapanim, northeast Pará, using direct observation techniques in the field, application of semi-structured questionnaires, ethnographic notes and guided tour in homegardens. Were identified 107 plant species and 12 animals. These data show that there is a greater number of species compared to other studies, which can be inferred large traditional knowledge used in the creation and diversification of these land use systems in the study site, considering the low technological level and family labor employees. Thus, these characteristic spaces of the countryside of family farmers in northeast Pará match key elements of their agricultural ecosystems, generating production and ensuring the reproduction of families.

Description
An account of the resource
This work was accomplished in Nova Friburgo, highland region of Rio de Janeiro State. It was studied two rural properties whose producers use organic and natural management of the soil. The natural management differs from the organic for not using crop rotation and organic fertilization with animal dejections. The two rural properties present distinct soil classes; therefore, a comparison among the two soil management systems was not possible. The study had as main objective to evaluate the degree of modification of soil properties in areas submitted to organic and natural management. In each area soil samples were collected under crop areas and control. In natural management, the control was a fallow area. In organic management, the control was a secondary forest area. The results showed that in the area under natural crop management levels of Ca, Ca+Mg, P and pH in water were statistically higher, when compared to the control. For H+Al, the highest values occurred in the reference area, when compared to cultivated areas. In the organic management, higher values of Ca, Ca + Mg, Na, K and P were observed in the crop area in all depths. However, for H + Al and NO3 - , the higher values were found in the control area. A degradation of the soil physical properties in the area under natural management was indicated by variation in aggregate stability and soil bulk density, but the organic management has benefited those properties. The selected and evaluated variables were capable to discriminate the different management systems studied by the main components analysis.Foram estudadas duas propriedades rurais em Nova Friburgo, RJ, com sistemas alternativos de produção, manejo orgânico e manejo natural do solo. O manejo natural difere do orgânico por não utilizar rotação de culturas e adubação orgânica com dejetos animais. As propriedades rurais apresentam classes de solos distintas, não sendo possível haver uma comparação entre os sistemas de manejo. O estudo teve como objetivo, avaliar o grau de modificação das propriedades edáficas em áreas submetidas aos manejos orgânico e natural. Em cada área foram coletadas amostras de terra sob áreas de cultivo e testemunha. No manejo natural, a testemunha foi uma área em pousio. No manejo orgânico, a testemunha foi uma área de floresta secundária. Os resultados mostraram que os teores de Ca, Ca + Mg, P e pH na área sob manejo natural, foram mais altos e estatisticamente significativos sob cultivo, quando comparados à área testemunha. Para o conteúdo de H + Al, os maiores valores ocorrem na área testemunha, em relação à área de cultivo. No sistema de manejo orgânico foram verificados maiores valores de Ca, Ca + Mg, Na, K e P na área sob cultivo, em todas as profundidades. No entanto, para H + Al e NO3 -, os maiores valores foram encontrados na área testemunha. Observou-se uma deterioração das propriedades físicas do solo (DMP e Ds) na área sob manejo natural. Em relação ao manejo orgânico, este beneficiou essas propriedades. As variáveis selecionadas e avaliadas por meio da análise de componentes principais serviu para discriminar as formas de manejo estudadas.

O trabalho discute as razões pelas quais se considera ainda necessário no Brasil a implementação de políticas agrícolas e agrárias voltadas para pequenos produtores familiares. São criticadas as visões predominantes, comuns tanto à esquerda quanto à direita, baseadas em falsas analogias com o caso dos países desenvolvidos, as quais consideram que não há mais espaço no país para políticas do tipo proposto. A importância da produção familiar é enfatizada também através de uma breve apresentação dos dados do censo agrícola do IBGE. Finalmente, na seção conclusiva do trabalho são apresentadas algumas propostas de desenvolvimento rural sustentável baseado na produção familiar.

Description
An account of the resource
This research focused on understanding the effects of structural heterogeneity within tree crowns on the airborne retrieval of solar-induced chlorophyll fluorescence (SIF) and the Crop Water Stress Index (CWSI). We explored the SIF and CWSI variability observed within crowns of trees subjected to different water stress regimes and its effect on the relationships with leaf physiological measurements. High-resolution (20 cm) hyperspectral imagery was acquired to assess fluorescence retrieval from sunlit portions of the tree crowns using the Fraunhofer line depth method, and from entire crowns using automatic object-based tree crown detection methods. We also measured the canopy temperature distribution within tree crowns using segmentation algorithms based on temperature percentiles applied to high-resolution (25 cm) thermal imagery. The study was conducted in an almond orchard cultivated under three watering regimes in Cordoba, in southern Spain. Three airborne campaigns took place during the summer of 2015 using high-resolution hyperspectral and thermal cameras on board a manned aircraft. Relationships between SIF and the assimilation rate improved significantly when the sunlit tree crown pixels extracted through segmentation were used for all flight dates. By contrast, the SIF signal extracted from the entire tree crowns was highly degraded due to the canopy heterogeneity observed within tree crowns. The quartile crown segmentations applied to the thermal images showed that the CWSI values obtained were within the theoretically expected CWSI range only when the pixels were extracted from the 50th percentile class. However, the CWSI values were biased in the upper quartile (Q75) for all watering regimes due to the soil background effects on the calculated mean crown temperature. The relationship between the CWSI and Gs was heavily affected by the crown segmentation levels applied and improved remarkably when the CWSI values were calculated from the middle quartile crown segmentation (Q50), corresponding to the coldest and purest vegetation pixels (r2 = 0.78 in pure vegetation pixels vs. r2 = 0.52 with the warmer pixels included in the upper quartile). This study highlights the importance of using high-resolution hyperspectral and thermal imagery for pure-object segmentation extractions from tree crowns in the context of precision agriculture and water stress detection.

As lâmpadas foram desenvolvidas da tecnologia incandescente, para a fluorescente e para o diodo emissor de luz (LED), o que aumentou a eficiência na conversão da iluminação e estendeu a vida útil do produto, consequentemente ocasionando na diminuição dos impactos ambientais. No entanto, a melhoria da fase de uso das lâmpadas, exige um sistema de produção mais complexo, incluindo (por vezes) materiais perigosos, o que piorou também sua disposição final. Estudos de Avaliação do Ciclo de Vida (ACV) são desenvolvidos desde 1996 envolvendo lâmpadas, e agora, com a evolução da tecnologia, as comparações estão ficando mais comuns. Esses estudos geram resultados variados, em que a unidade funcional (UF) desempenha um papel fundamental para gerar essas diferenças, mesmo quando os sistemas de produto são semelhantes, dificultando a compreensão das comparações. O objetivo deste artigo é analisar a produção científica de ACVs de lâmpadas, desenvolvendo um panorama dos sistemas de produto e suas definições de UF, bem como dos resultados, para indicar tendências e padrões da aplicação neste tema. A metodologia proposta foi de uma revisão integrativa da literatura aplicada a bases de dados científicos e outros documentos. A pesquisa identificou 16 artigos, onde ficou evidente o recente aumento dos estudos de ACVs comparativos. Nesta amostragem foram encontradas quatro diferentes definições de UF. Contudo, uma descrição complementar do desempenho do produto permite equalizar a UF numa base comum, em que os valores para a mudança climática têm mostrado que as lâmpadas LED são preferíveis às lâmpadas fluorescentes, que são preferíveis às incandescentes. Embora a comparação tenha sido possível, a UF deve ser claramente indicada para representar a função dos produtos, neste caso: a quantidade de lúmen.horas. Resumen Las lámparas se han desarrollado a partir de la tecnología incandescente, fluorescente, y un diodo emisor de luz (LED), lo que significa un aumento de la eficiencia de conversión de luz, que extiende la vida útil del producto y reduce así el impacto ambiental. Sin embargo, mejorar la fase de uso de las lámparas requiere un sistema de producción más complejo, incluyendo (a veces) materiales peligrosos, lo que empeora la disposición final. La Análisis del Ciclo de Vida (ACV) se ha dirigido a las lámparas desde 1996, y ahora con su evolución, las comparaciones son cada vez más comunes. Estos estudios llevan a resultados diferentes, donde la unidad funcional (UF) tiene un papel clave para la generación de estas diferencias, mismo cuando los sistemas de productos son similares, lo que dificultaría la comprensión general de las comparaciones. El objetivo fue analizar la producción científica de ACV de lámparas, el desarrollo de un marco de sistemas de productos, la definición de UF y los resultados para indicar tendencias y normas de aplicación de la metodología del ACV, incluyendo las posibilidades de comparabilidad. La metodología propuesta fue una revisión integrativa de la literatura aplicada a bases de datos científicas y análisis de contenido de documentos adicionales. La investigación identificó 16 artículos, donde está claro el reciente aumento en los estudios comparativos de ACV dirigidos a las tecnologías de iluminación. Había 4 diferentes definiciones de UF en los documentos. Sin embargo, la descripción adicional del rendimiento del producto permite equiparar el UF a una base común, donde los valores para el cambio climático han demostrado que las lámparas LED son mejores que las fluorescentes, que a su vez son preferibles que las incandescentes. Aunque esto podría ser posible, UF debe estar siempre claramente indicado y representar la función de los productos, en este caso la cantidad lúmen.hora de una lámpara Lamps have been developed since incandescent technology, to fluorescent and light emitted diode (LED), increasing lighting conversion efficiency, extending product’s life span, and, consequently, decreasing environmental impacts. However, improving the use phase of lamps demand a more complex production system, including (sometimes) hazardous materials, what have worsened final disposal as well. Life Cycle Assessment (LCA) has been addressed to lamps since 1996, and now with its evolution, comparisons are getting more common. These studies lead to different results, wherein functional unit (FU) plays a key role to generate these differences, even when product systems are similar, making difficult the overall understanding of comparisons. We aimed to analyze the scientific production of LCA of lamps, developing a framework of the product systems, the FU definition and the results to indicate trends and patterns of the LCA methodology application, including comparison possibilities. The proposed methodology was an integrative literature review applied to scientific databases and further papers content analysis. The survey identified 16 papers, where it is clear the recent increase on comparative LCA studies addressed to lighting technologies. There were 4 different FU definitions in papers. However, complementary description of product performance enable one to equalize FU into a common basis, wherein values for climate change have shown that LED lamps are preferable than fluorescents, that are preferable than incandescent. Even though this was possible, FU should be clearly indicated and represent products function, in this case: an amount of lumen-hour.

Description
An account of the resource
This study aims to present a research on the representation of family farmers process at institutional spaces of social participation. Data were obtained from City Council for Rural Development of Itapejara d’Oeste and Vitorino and Management Group of Southwest Territory of Paraná. These spaces, which are institutional spaces originated from the process of decentralization of state institutions and effort to develop civil society participation in state management, determine the emergence of a differentiated process of representation, played by representatives of different social groups present in these spaces. The representation is analysed considering two dimensions: the representatives representativeness and the representatives ability to intervene in the several spaces. The research shows that different configurations of spaces, trajectories of representatives and associative trajectories of municipalities and region alter the process of representation from the distinction of the profiles of the representatives, the forms of relationship between representatives and the represented and how their own institutional spaces of social participation are identified with the associative conformations of family farmers in the territory.

Resumo: O artigo tem como objetivo apresentar as implicações sociais, econômicas e ambientais da criação do Parque Nacional da Serra da Bodoquena, para uma comunidade de assentados. Verificaram-se as implicações da presença de um Parque Nacional na dinâmica do assentamento, nos seus desafios e potencialidades para os agricultores familiares e as novas oportunidades de diversificação de seu meio de vida. Metodologicamente o estudo baseou-se nas três dimensões do Desenvolvimento Sustentável propostas pela World Comission on Environmental Development - WCED (1987): Sociedade, Economia e Meio Ambiente, desmembrados em fatores ou critérios de sustentabilidade propostos por Altieri (1989), acrescidos da metodologia de análise de Fernandez (1995). Se pode identificar elementos que apontam a necessidade de se implementar programas de educação ambiental e de incorporação de novas tecnologias de produção compatíveis com os objetivos de preservação do Parque Nacional da Serra da Bodoquena. Palavras-chave: Assentamentos Rurais. Agricultura familiar. Unidades de Conservação. Parques Nacionais. Desenvolvimento Sustentável

O objetivo desse trabalho foi avaliar o efeito da colonização micorrízica arbuscular na tolerância da bananeira, cv. Maçã, ao mal-do-Panamá, sob diferentes fontes de nutrientes. Utilizou-se um delineamento inteiramente casualizado com fatorial 2 x 4 [2 densidades de esporos de FMA nativos (D1 - 3.500 esporos kg-1 solo e D2 - 7.000 esporos kg-1 solo) e 4 diferentes concentrações de fontes de nutrientes - três de solução nutritiva (SN 40%, SN 70% e SN 100%) e uma de biofertilizante 100% (B4)] com três repetições. Após o plantio inoculou-se Fusarium oxysporum f.sp. cubense e posteriormente avaliou-se matéria seca da parte aérea (MSPA), o teor de fósforo foliar (P), a colonização micorrízica, o pH do solo e o índice de severidade da doença (ID). As diferentes fontes de nutrientes influenciaram a matéria seca da parte aérea, o teor de fósforo, a colonização micorrízica e o índice de severidade da doença, porém não influenciaram o pH da solução do solo. O biofertilizante não atendeu à demanda nutricional das plantas, as quais se mostraram pouco desenvolvidas. Porém proporcionou intensa colonização micorrízica e menor índice de severidade da fusariose, o qual aumentou com a adubação mineral.The aim of this study was to evaluate the effect of the colonization of arbuscular mycorrhiza on the tolerance to Panama disease of the banana plant cv. maçã under different sources of nutrients. A completely randomized design was employed, having a 2 x 4 factorial [2 densities of native FMA spores (D1 - 3,500 spores kg-1 soil and D2 - 7000 spores kg-1 soil) and four different concentrations of nutrient sources - three of a nutrient solution (SN 40%, SN 70% and SN 100%) and a 100% solution of bio-fertiliser (B4)], with three replications. After planting, the seedlings were inoculated with Fusarium oxysporum f.sp. cubense, and later the shoot dry matter, leaf phosphorus content, mycorrhizal colonization, soil pH and disease severity index were evaluated. The different nutrient sources affected the shoot dry matter, the phosphorus content, the mycorrhizal colonization and the disease severity index, but did not affect the pH of the soil-solution. The bio-fertiliser did not meet the nutritional demands of the plants, which remained underdeveloped, however it promoted intense mycorrhizal colonization and lower manifestations of fusarium. The latter increased under mineral fertilization.
