Brazil may appear to be a good student regarding food security and governance. Indeed, it implemented a national policy for food and nutrition security (FNSP) which is simultaneously unsectoralised, participatory and decentralised. The advocated model is the result of a significant contribution from social movements whose proposals have nurtured public policies during the last decade and have replaced the global food security framework with that of food sovereignty. This article aims to analyse the social changes that have accompanied the promotion of food sovereignty, which stands as a legacy to the history of the fight against hunger in Brazil. Since the end of the dictatorship, actions towards food sovereignty have been carried out in an unstable context of two development benchmarks within the State itself. The institutional commitment associated with it is epitomised under Lula by the arrival of managers close to social movements in a State still partly in the hands of traditional rural elites. In fact, two agrifood systems clashed and entered into open conflict after the destitution of Dilma Rousself. On the one hand, agribusiness, whose political aim is that of ecological modernization, drove a techno-environmental system. On the other hand, the world of NGOs, social movements and representatives of the left-wing government were united under the banner of a socio-ecological system: agroecology. Both social movements and agribusiness, amidst an unceasing struggle for power, attempted to build a certain level of unity in order to strengthen their networks of influence and increase their penetration within society. The end of institutionalised duality begs the question of the ability of these two models to coexist or even possibly evolve to become a hybrid of the two.Keywords: food security; agroecology; agrobusiness; agricultural models; social movements.PINTON, Florence; YANNICK, Sencebe.

Genetic characterization of local breeds is essential to preserve their genomic variability, to advance conservation policies and to contribute to their promotion and sustainability. Genomic diversity of twenty European local pig breeds and a small sample of Spanish wild pigs was assessed using high density SNP chips. A total of 992 DNA samples were analyzed with the GeneSeek Genomic Profiler (GGP) 70 K HD porcine genotyping chip. Genotype data was employed to compute genetic diversity, population differentiation and structure, genetic distances, linkage disequilibrium and effective population size. Our results point out several breeds, such as Turopolje, Apulo Calabrese, Casertana, Mora Romagnola and Lithuanian indigenous wattle, having the lowest genetic diversity, supported by low heterozygosity and very small effective population size, demonstrating the need of enhanced conservation strategies. Principal components analysis showed the clustering of the individuals of the same breed, with few breeds being clearly isolated from the rest. Several breeds were partially overlapped, suggesting genetic closeness, which was particularly marked in the case of Iberian and Alentejana breeds. Spanish wild boar was also narrowly related to other western populations, in agreement with recurrent admixture between wild and domestic animals. We also searched across the genome for loci under diversifying selection based on FST outlier tests. Candidate genes that may underlie differences in adaptation to specific environments and productive systems and phenotypic traits were detected in potentially selected genomic regions.

Governance of Local Productive Arrangements (LPAs), territorial networks and proximities in the Brazilian Amazon: The Case of the Goiaba LPA in Northeastern Pará : Proximities’ influence on the construction of socio-economic networks provokes many debates in the literature. The present contribution aims to study the functioning of coordination between actors in support systems for agricultural sectors and to highlight the impact of a public policy of territorial development on these devices, with the help of an approach in terms of networks and proximities. For that, we analyze the Local Productive Arrangements (LPAs) of an agricultural sector in the Brazilian Amazon, supported by a territorial governance mechanism. The mobilized analysis framework allows us to study and compare LPAs, to characterize the types of networks according to the types of proximities and to highlight the importance of the territorial governance mechanism for strengthening and sustaining LPAs.; L’influence des proximités sur la construction des réseaux socio-économiques suscite de nombreux débats dans la littérature. La présente contribution vise à étudier le fonctionnement des coordinations entre acteurs dans des dispositifs d’appui aux filières agricoles et à mettre en évidence l’impact d’une politique publique de développement territorial sur ces dispositifs, à l’aide d’une approche en termes de réseaux et de proximités. Dans cet esprit, à partir de données relationnelles collectée entre avril 2012 et mars 2013, nous analysons un Arrangement Productif Local (APL) d’une filière agricole en Amazonie brésilienne, soutenus par un dispositif de gouvernance territoriale. Le cadre d’analyse mobilisé nous permet d’étudier et de comparer des APL, de caractériser les types de réseaux selon les types de proximités et de mettre en avant l’importance du dispositif de gouvernance territoriale pour le renforcement et la pérennisation des APL.; A influência das proximidades na construção das redes socioeconômicas suscita inúmeros debates na literatura. A presente contribuição visa estudar o funcionamento das coordenações entre atores em dispositivos de apoio às cadeias produtivas agrícolas e evidenciar o impacto de uma política pública de desenvolvimento territorial sobre esses dispositivos, com a ajuda de uma abordagem em termos de redes e de proximidades. Com esse intuito, a partir de dados relacionais primários coletados entre abril de 2012 e março de 2013, analisamos um Arranjo Produtivo Local (APL) de uma cadeia produtiva agrícola na Amazônia brasileira, apoiados por um dispositivo de governança territorial. O quadro de análise mobilizado, nos permite estudar e comparar os APLs, caracterizar os tipos de redes segundo os tipos de proximidades e destacar a importância do dispositivo de governança territorial para o fortalecimento e a perenização dos APLs.

The present article discusses the best practices of the Petroleum Industry, by explaning the doctrine definition for this expression, characterizing the authors who elaborate these practices and pointing out their legal provisions in the Brazilian regulatory framework. There are some considerations that can be explained on the legal interpretation of the best practices, by comparing the two contrasting theories: the Pure Theory of Law by Kelsen and the Theory of Droit en Reseaux by F. Ost and M. Kerchove. The latter is more suitable to analyze the best practices under the approach of the Transnational Petroleum Law. Lastly, the importance of keeping Brazilian Petroleum Agency (ANP) regulators updated on the best practices will be highlighted, in order to monitor their application and comply with the legal provision of the Production Sharing Agreement (PSA) Law., O presente artigo discorre sobre as melhores práticas, apresentando a conceituação da doutrina sobre esse instituto, caracterizando os autores que as elaboram e apontando sua previsão na legislação e nos contratos para outorga de direitos de exploração e produção brasileiros. São expostas algumas reflexões sobre sua interpretação jurídica, confrontado a Teoria Pura do Direito de Kelsen com a Teoria do Droit em Reseaux de F. Ost e M. Kerchove, tomando esta como base para considerar o Direito Transnacional do Petróleo como o ramo adequado para a análise das melhores práticas. Por fim se ressalta a importância de os reguladores estarem atualizados sobre as melhores práticas, para que possam exigir sua aplicação, atendendo assim o ditame legal da Lei da Partilha

Des éleveurs français, membres de coopératives d'utilisation de matériel agricole (CUMA), cherchent à devenir plus autonomes par rapport aux marchés. Pour cela, ils développent de nouvelles pratiques et s'appuient sur une coopération accrue entre pairs. Notre communication, basée sur l'étude de six CUMA, cherche à apporter un nouvel éclairage sur ce phénomène, à partir du cadre analytique de Ploeg, qui a identifié six mécanismes par lesquels les agriculteurs construisent leur autonomie. Ces éleveurs développent de nouvelles pratiques, dont certaines peuvent être qualifiées d'agroécologiques, grâce à la coopération entre pairs. Une plus grande interdépendance entre eux résulte de l'approfondissement de leurs modes de coopération, tout en leur fournissant plus de marges de manœuvre. Cependant, ils manquent de ressources appropriées de la part des autres opérateurs du secteur agri-alimentaire pour limiter les dépendances restantes. Nous concluons en argumentant que la coopération entre pairs et la recherche d'autonomie méritent plus d'attention afin d'aider à renforcer les processus d'adaptation et de transition agroécologique d'une plus grande diversité d'éleveurs., Muitos pecuaristas franceses, sócios de cooperativas de maquinas, procuram se tornar mais autônomos em relação aos mercados. Para concretizá-lo, eles desenvolvem novas práticas através de uma maior cooperação entre produtores. Nosso trabalho, baseado na análise de seis cooperativas de maquinas, visa esclarecer esse fenômeno, com base no trabalho analítico de Ploeg, que identificou seis mecanismos pelos quais os agricultores constroem autonomia. Estes pecuaristas desenvolvem novas práticas, algumas das quais podem ser chamadas como agroecológicas, através da cooperação entre produtores. Uma maior interdependência entre eles resulta da intensificação destas cooperações, enquanto aumenta o espaço de manobra dos pecuaristas. No entanto, eles faltam de recursos apropriados da parte dos outros operadores do setor agri-alimentar para limitar as dependências restantes. Concluímos argumentando que a cooperação entre produtores e sua busca por autonomia merecem mais atenção para ajudar a fortalecer os processos de adaptação e transição agroecológica de uma maior diversidade de pecuaristas.

The aim of this work was to analyse the distribution of causal and candidate mutations associated to relevant productive traits in twenty local European pig breeds. Also, the potential of the SNP panel employed for elucidating the genetic structure and relationships among breeds was evaluated. Most relevant genes and mutations associated with pig morphological, productive, meat quality, reproductive and disease resistance traits were prioritized and analyzed in a maximum of 47 blood samples from each of the breeds (Alentejana, Apulo- Calabrese, Basque, Bísara, Majorcan Black, Black Slavonian (Crna slavonska), Casertana, Cinta Senese, Gascon, Iberian, Krškopolje (Krškopoljski), Lithuanian indigenous wattle, Lithuanian White Old Type, Mora Romagnola, Moravka, Nero Siciliano, Sarda, Schwäbisch-Hällisches Schwein (Swabian Hall pig), Swallow-Bellied Mangalitsa and Turopolje). We successfully analyzed allelic variation in 39 polymorphisms, located in 33 candidate genes. Results provide relevant information regarding genetic diversity and segregation of SNPs associated to production and quality traits. Coat color and morphological trait-genes that show low level of segregation, and fixed SNPs may be useful for traceability. On the other hand, we detected SNPs which may be useful for association studies as well as breeding programs. For instance, we observed predominance of alleles that might be unfavorable for disease resistance and boar taint in most breeds and segregation of many alleles involved in meat quality, fatness and growth traits. Overall, these findings provide a detailed catalogue of segregating candidate SNPs in 20 European local pig breeds that may be useful for traceability purposes, for association studies and for breeding schemes. Population genetic analyses based on these candidate genes are able to uncover some clues regarding the hidden genetic substructure of these populations, as the extreme genetic closeness between Iberian and Alentejana breeds and an uneven admixture of the breeds studied. The results are in agreement with available knowledge regarding breed history and management, although largest panels of neutral markers should be employed to get a deeper understanding of the population’s structure and relationships.

This study aims to determine the digestibility of milk by the young rabbit (21-25d old), taking into account the increment of digesta content and urine excretion. Nineteen litters of nine young rabbits of 21 to 25 days old were used: 12 litters fed exclusively with milk using a controlled suckling (CS group), and 7 litters with free suckling and having access to the pelleted feed of the doe (Control group). The faecal digestibility of milk dry matter was measured between 21 and 25d of age, for CS litters housed in a metabolism cage separated from the doe cage from 15 d old. Between 21 and 25d old, milk intake, feces and urine excretion were daily controlled, and themean increment in digesta content was measured by comparing digesta weight of the whole tract at 21 and 25d old (one kit per litter). Between 21 and 25d, the increment in digesta content averaged by 77% (+8.5 g), sourcing mainly from stomach and caecum contents increase (+57% and +120% resp.). The mean increase for the dry content of the gut (DCGi) from 21 to 25d old was 1.73g DM/kit, and was considered as non digested to calculate the corrected digestibility coefficient of the milk. The milk intake averaged 30 g/d/kit (7.9 g DM/d/kit). No faecal excretion was recorded between 21 and 25d. From the milk intake and increment in digesta content, the corrected digestibility of the milk dry matter reached 78% (minimum=72.1%, maximum = 82.5%). The daily urine excretion averaged 5.1 ml/kit, corresponding to 1.2 g DM/kit. Therefore, the corrected DM retention coefficient of the milk was 63.4%. The quantity of nitrogen excreted in urine was low (0.06g/d/kits), thus the corrected nitrogen retention coefficient for milk reached 82%, and the nitrogen retained (corrected) reached 44 g/d/kit. Accordingly the amount in metabolisable protein for the milk was 90 g/kg (fresh). The corrected energy retention coefficient was estimated to 95%, thus the energy retained (corrected) reached 217 kJ/d/kit, and the content in metabolisable energy for the milk was 27.62 kJ/kg (fresh)., Este estudo tem como objetivo determinar a digestibilidade do leite de laparos, levando em consideração a acúmulação do conteúdo digestivo e a excreção de urina. Foram utilizadas 19 ninhadas de nove laparos de 21 a 25 dias cada uma: 12 ninhadas foram sobmetidas ao aleitamento restringido sem acesso ao comedouro da coelha (grupo CS) e 7 ninhadas com aleitamento a vontade e livre acesso à raçãoda coelha (grupo controle). A digestibilidade fecal do leite foi medida entre 21 e 25 dias de idade, para as ninhadas CS alojadas em gaiolas de digestibilidade a partir dos 15 dias de idade. Entre 21 e 25 dias de idade, o consumo de leite e a excreção de fezes e urina foram medidos diariamente. No referente ao incremento médio do conteúdo digestivo, este foi medido pela diferença de peso do trato digestivo entre os dias 21 e 25d anos (um laparos por ninhadas). Entre 21 e 25 dias, o incremento médio do conteúdo digestivo foi de 77% (+8,5 g), proveniente principalmente do aumento do conteúdo do estômago e do ceco (+ 57% e +120%, respectivamente). O aumento médio do conteudo intestinal seco (DCGi) entre 21 e 25 dias foi de 1,73g de materia seca (MS)/laparo. Este valor foi considerado não digerido para corrigir o coeficiente de digestibilidade do leite. Em media, a ingestão de leite para cada laparo foi de 30 g / dia (7,9 g de MS/dia). Nenhuma excreção fecal foi recuperada entre 21 e 25 dias. A partir dos dados de consumo de leite e do incremento do conteudo digestivo, a digestibilidade corregida da matéria seca do leite foi de 78% (mínimo = 72,1%, máximo = 82,5%). A excreção media diaria de urina foi de 5,1 ml/laparo, o que corresponde a 1,2 g de MS / laparo. Portanto, o coeficiente corrigido de retenção de MS do leite foi de 63,4%. A quantidade de nitrogênio excretada na urina foi baixa (0,06 g/dia/laparo), resultando em um 3 coeficiente de retenção de nitrogênio de 82%, e uma quantidade de nitrogênio retido (corrigido) de 44 g/dia/laparo. Portanto, a quantidade de proteína metabolizável do leite de coelhas foi de 90 g / kg de leite fresco. O coeficiente corregido de retenção de energia foi estimado em 95%, resultando em uma quantidade diaria de energia retida de 217 kJ/laparo. O conteúdo de energia matabolisada do leite fresco de coelhas foi de 27,62 kJ/kg.

International audience; This paper aims to analyze the emissivity and surface temperature for the agglomeration of Rennes, France. For this, two formulas of emissivity (estimated from the Normalized Difference Vegetation Index, NDVI data) were used and their results were compared. The estimation of surface temperature was conducted from the emissivity data obtained in the previous stage. The form of the surface heat island (SHI) varied according to the emissivity used and the season. We conclude that the two formulations can be used for calculating the surface temperature and that the vegetation and its water content was shown to be an important variable in the analysis emissivity and surface temperature in the temperate zone.

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. This is an author-deposited version published in: https://sam.ensam.eu Handle ID, O presente trabalho tem como objetivo discutir a estimativa de incertezas em ACV, utilizando três procedimentos de cálculo a partir de dados de inventários da produção de blocos cerâmicos de uma fábrica localizada no Estado de São Paulo (berço ao portão). O primeiro procedimento para a estimativa de incertezas consistiu na atribuição de modelos probabilísticos e seus parâmetros aos valores obtidos na fábrica. As distribuições de probabilidade foram selecionadas dentre as disponíveis no Simapro (versão 8.1.1.16). O segundo procedimento consistiu na aplicação das diretrizes do Ecoinvent versão 3.1 relativas a incertezas, adotandose valores padronizados de incerteza básica e incertezas adicionais da matrizPedigree, com distribuição lognormal. O terceiro procedimento consistiu em uma mescla dos procedimentos prévios: adotou-se o primeiro procedimento para o cálculo da incerteza básica e a matriz Pedigree para a atribuição da incerteza adicional. Os ICVs foram inseridos com suas respectivas incertezas no Simapro e foram feitas simulações de Monte Carlo com parâmetros equivalentes para as trêssituações. Realizaram-se também análises de variância (ANOVA) para verificar a distribuição das incertezas entre o processo principal e os processos a montante. Observou-se que os procedimentos 1 e 2 são passíveis de adoção em estudos de ACV, a depender da disponibilidade de recursos e do nível de detalhamento do estudo em questão, sendo que o primeiro procedimento, que envolve o cálculo direto dasincertezas associadas, tem potencial de agregar maior confiabilidade ao estudo de ACV, enquanto o segundo requer menor esforço para a estimativa de incertezas. Ambas as abordagens melhoram a qualidade do resultado final a ser comunicado em relação à divulgação de um valor determinístico único.

International audience; Este trabalho teve como objetivo desenvolver o inventário de ciclo de vida para madeira empregada na estrutura de telhado de edificações populares do Estado de São Paulo, com base na adaptação de inventários existentes na base de dados ecoinvent (versão 3.1) para a realidade da produção madeireira no Brasil. Considerou-se como sistema de produto a produção de 1m3 de madeira serrada de cambará proveniente de manejo florestal sustentável na Amazônia, desde a extração das toras até a peça de madeira serrada estocada em São Paulo. As informações nacionais foram obtidas da literatura. A despeito das semelhanças entre o sistema de produto da base ecoinvent e a realidade nacional na extração das toras na floresta, há diferenças referentes ao transporte até a serraria, ao desdobro das toras e à geração e destinação de resíduos: no Brasil, todas as etapas são executadas próximas à região de exploração, resultando em alterações no modelo de transporte, máquinas empregadas e resíduos gerados. Além disso, os valores de consumo de diesel e eletricidade apresentaram ordens de grandeza diferentes dos ICVs de referência. Com base nessa análise, conclui-se que a estrutura de dados dos ICVs existentes na base ecoinvent auxilia a construção de inventários nacionais e que a adaptação dos inventários é imprescindível para a realização de estudos de avaliação do ciclo de vida condizentes com as condições do Brasil. Entretanto, considerando as diferenças observadas, é recomendada a apuração dos índices de consumo nacionais por meio de verificação e coleta de dados inloco

International audience; Differences in the temperatures of targets diagnosed by thermal imagery of satellite landsat 8 in dry and rainy seasons in a tropical environment This article aims to compare the intensities of surface heat islands diagnosed from thermal images (band 10) of the satellite Landsat 8 in Presidente Prudente, medium-sized city located in a tropical environment in dry and rainy seasons. In addition to the temperature charts of targets, rhythmic analysis charts were developed as proposed by Monteiro (1971) to analyse the weather characteristics in the days before the taking of images. The results showed that the differences in surface temperatures between rural and urban were high in the rainy season. In the dry season, with the dominance of bare soil, the radiative properties of the surfaces were similar, homogenizing temperatures between rural and urban.; Este artigo tem como objetivo comparar as intensidades das ilhas de calor superficiais diagnosticadas a partir de imagens termais (banda 10) do satélite Landsat 8, em Presidente Prudente, cidade de porte médio localizada no ambiente tropical, em período seco e chuvoso. Além das cartas de temperatura dos alvos foram elaborados gráficos de análise rítmica, segundo a proposta de Monteiro (1971) para se analisar as características do tempo nos dias que antecederam as tomadas das imagens. Os resultados mostraram que as diferenças das temperaturas superficiais entre o rural e o urbano foram elevadas na estação chuvosa. Na estação seca, com o predomínio do solo sem vegetação, as propriedades radiativas das superfícies ficaram semelhantes, homogeneizando as temperaturas entre o rural e o urbano.

Nowadays, the studies concerning to the populational movement runs through several geographical analysis scales highlighting its contradictions and conflicts as reflections of the globalization era. Globalization has conditioned the emergence of a class of workers unskilled in different branches of economic activities, being deterritorialized, precarious and dispossessed of their means of production. Such workers seek through forced mobility, better life and work conditions. This context reflects the current situation of relative labour force, especially related to young adults coming from the north-eastern region, linked to the sugarcane industry in Brazil. The absence of opportunities in certain Brazilian regions consubstantiated the neglect of local politicians have been hindering population retaining young adults in their home environment. This research has identified a class of Northeastern rural workers who migrates temporarily or permanently, to the Paranaense Northwest to join in cutting sugarcane or cassava. In this manner, the objective of this thesis is to investigate the Northeastern labor force in the Paranaense Northwest and its effects on the production of the geographic area of the municipality of Tamboara-PR. It also signals the municipality of Jardim-CE, city of origin of many immigrants from Tamboara to propose new economic activities guided by the alternative economy and the social and solidarity economy as eradication of forced mobility possibilities to paranaenses sugarcane fields. Such activities consist of population restraint devices and counter-hegemonic resistance face of globalization and the hegemonic globalization of social organization., Atualmente os estudos acerca do movimento populacional perpassam diversas escalas geográficas de análise, ressaltando suas contradições e conflitos como reflexos da era da globalização. A globalização condicionou o aparecimento de uma classe de trabalhadores desqualificados em diferentes ramos das atividades econômicas, desterritorializados, precarizados e expropriados de seus meios de produção. Tais trabalhadores buscam por meio da mobilidade forçada melhores condições de vida e trabalho. Este contexto reflete a situação atual de uma relativa força de trabalho, sobretudo de jovens adultos oriundos da região nordestina, ligada ao setor canavieiro do Brasil. A falta de oportunidades em determinadas regiões brasileiras consubstanciada a negligencia dos agentes políticos locais têm dificultado a retenção populacional de jovens adultos em seu meio de origem. Esta pesquisa de doutorado identificou uma classe de trabalhadores rurais nordestinos que migram, temporariamente ou de forma definitiva, ao Noroeste Paranaense para ingressar no corte da cana-de-açúcar ou na mandiocultura. Deste modo, o objetivo desta tese é investigar a força de trabalho nordestina no Noroeste Paranaense e seus reflexos na produção do espaço geográfico do município de Tamboara-PR. Sinaliza-se também o município de Jardim-CE, localidade de origem de muitos migrantes de Tamboara, para propor novas atividades econômicas pautadas na economia alternativa e na economia social e solidária como possibilidades de erradicação da mobilidade forçada aos canaviais paranaenses. Tais atividades consistem em dispositivos de retenção populacional e em resistências contra-hegemônicas face à mundialização e à globalização hegemônica de organização social.

Supplementation with forages ,Substitution rate ,Milk response ,[SDV.AEN]Life Sciences [q-bio]/Food and Nutrition - Abstract
Supplementing grazing dairy cows with corn silage is a practice for increase the individual milk production in periods with low available pastures. However, the effects of supplementation with conserved forages on pasture intake and productive responses of grazing dairy cows has been little studied. The objectives of this study were understand the main factors with effect on pasture intake and milk production responses of grazing dairy cows supplemented with conserved forages. For this, three experiments and a literature study in the form of meta-analysis were performed. At first experiment we tested the effects of the levels of supplementation (0, 4 and 8 kg DM of corn silage ) on pasture intake and productive responses of cows grazing at medium pasture allowance (PA), with on average 35 kg DM/d above the ground level. In the second experiment, the effects of increasing the PA on substitution rate and productive response were tested. In this case, we worked with two supplementation levels (0 and 4 kg DM silage maize) and two PA (25 and 40 kg DM/d above ground level). In the third experiment, we tested the effects of supplementation with 5 kg DM of corn silage in two contrasting PA (15 and 30 kg DM above 3.0 cm from the ground) and also a management strategy, with objective to target a similar post-grazing sward height of unsupplemented cows. The first two experiments were performed in Lages, SC, Brazil in the winters of 2011 and 2012. The third experiment was conducted at INRA, France during the spring of 2014. In the three experiments similar measures on animals were made. It were measured pasture and supplement intake, milk production and composition, and the animal behaviour. The individual pasture intake and milk production and composition were measured in all experiments It were also carried out measures on pre- and post-grazing pasture characteristics. The amount of available pasture and the pasture structure are crucial to the response to supplementation with corn silage for grazing dairy cows. At low pasture allowance, the supplementation with corn silage can increase the total DM intake and the individual milk production However, by adopting a management strategy to reduce the post-grazing sward height, the substitution rate increases and the total DM intake is not affected by supplementation , even in low PA.; A suplementação com silagem de milho é uma das ferramentas de manejo disponíveis para manter a produção individual de vacas leiteiras em pastejo quando a quantidade de pasto disponível aos animais é reduzida. No entanto, os efeitos da suplementação com forragens no consumo do pasto e na resposta produtivas destes animais tem sido pouco estudados. Os objetivos desta tese foram identificar e compreender os principais fatores que afetam o consumo do pasto de vacas em lactação quando suplementadas com forragens conservadas. Para isso, foram realizados 3 experimentos e um estudo de literatura na forma de meta-análise. No primeiro buscamos compreender os efeitos do níveis da suplementação (0, 4 e 8 kg de MS de silagem de milho) no consumo do pasto e resposta produtiva de vacas manejadas em uma oferta diária de pasto de 35 kg de MS acima no nível do solo. No segundo foram testados os efeitos do aumento da oferta do pasto na taxa de substituição e resposta produtiva. Neste caso, trabalhos com dois níveis de suplementação (0 e 4 kg de MS de silagem de milho) e duas ofertas contratantes de pasto (25 e 40 kg de MS/ dia em nível do solo). No terceiro experimento foram testados os efeitos da suplementação com 5 kg de MS de silagem de milho em duas ofertas de pasto contrastantes (15 e 30 kg de MS acima de 3,0 cm do solo) e também uma estratégia de manejo que visa a redução da altura de saída dos pastos de vacas suplementadas com silagem, afim de reduzir os efeitos negativos da taxa de substituição. Os dois primeiros experimentos foram conduzidos em Lages, nos invernos de 2011 e 2012. O terceiro experimento foi realizado no INRA, França durante a primavera de 2014. Nos três experimentos foram feitas medidas semelhantes sobre os animais. Em todos eles foram medidos o consumo de pasto, o consumo de suplemento, produção e composição de leite, além do comportamento alimentar. Foram realizadas também medidas sobre o pasto, buscando caracterizá-lo antes e após o pastejo. Pode-se afirmar que a quantidade de pasto disponível, bem como a sua estrutura são determinantes para a resposta à suplementação o com silagem de milho para vacas leiteiras em pastejo. Em situações de oferta restrita, a suplementação com silagem promove o aumento do consumo de MS total e consequentemente da produção de leite. Entretanto, ao adotarmos estratégias de manejo que visam a redução da altura residual do pasto de vacas suplementadas com forragens conservadas, a taxa de substituição aumenta e o consumo de MS total não é afetado pela suplementação, mesmo em situações de baixa oferta diária de pasto.

To quantify the emissions of nitrous oxide (N2O) resulting from the faeces and urine of dairy cows grazing temperate grasslands and investigate alternatives to promote the efficient use of feed nitrogen and reduce emissions of methane as well without reducing the animal performance, three experiments were conducted. The first experiment aimed quantify the potential of soil (N2O) emissions as a function of nitrogen excretions from the faeces and urine of grazing dairy cows. In the second and third experiments the effect of concentrate supplementation with or without Acacia mearnsii tannin extract was evaluated as an alternative to promote the efficient use of feed nitrogen in dairy cows grazing temperate or tropical pastures and reduce methane emissions in tropical pastures. The results of the first experiment showed that soil N2O flux emission was affected by urinary excretion of dairy cows, but does not by faecal excretion.. In the second experiment was observed that energetic supplementation is a tool to improve nutritional status and animal performance of dairy cows from mid to late lactation grazing annual temperate pastures, whereas tannin extract improve the energetic balance. In the third experiment, the inclusion of tannin extract in the supplement of dairy cows reduced enteric methane emissions without decreasing the animal performance. In the last two experiments, the tannin extract supplementation did not improve the efficiency of using the feed nitrogen to dairy cows at mid-lactation.; Com o objetivo quantificar as emissões de óxido nitroso (N2O) advindas das fezes e urina de vacas em pastos de clima temperado e investigar alternativas para promover a eficiência da utilização do nitrogênio alimentar, bem como reduzir as emissões de metano, sem prejuízo ao potencial produtivo de vacas leiteiras foram realizados três experimentos. O primeiro experimento objetivou quantificar o potencial de emissão de N2O do solo em função das emissões nitrogenadas advindas das fezes e urina de vacas leiteiras em pastejo. No segundo e terceiro experimentos foram realizados ensaios de desempenho de vacas leiteiras em pastagens de inverno e verão, avaliando o uso da suplementação com alimentos concentrados com ou sem a adição de extrato tanífero de Acacia mearnsii como alternativa para promover a eficiência da utilização do nitrogênio alimentar, e reduzir as emissões de metano. Os resultados do primeiro experimento demostraram que o fluxo de emissão de N2O do solo é significativamente afetado pela excreção urinária de vacas leiteiras, mas não pela. Estes resultados sugerem que um manejo nutricional de vacas leiteiras que privilegie a melhor eficiência do uso do N alimentar, reduzindo a excreção urinária de N, pode contribuir na redução das emissões de N2O. No segundo experimento foi observado que a suplementação energética é uma ferramenta para melhoria do status nutricional e do desempenho de vacas leiteiras no terço médio de lactação em pastos anuais de inverno. O extrato tanífero contribuiu para a melhoria do balanço energético, mas não apresentou efeito sobre o desempenho produtivo. No terceiro experimento a inclusão de extrato tanífero no suplemento de vacas leiteiras em pastagem de verão resultou em importante redução na emissão de metano entérico, sem afetar o desempenho produtivo. Em ambos os ensaios de desempenho animal, não é possível afirmar que a inclusão dietética de extrato tanífero para vacas leiteiras no terço médio de lactação resulte em melhora significativa da eficiência de utilização do nitrogênio alimentar.

National audience; Este trabalho teve como objetivo realizar uma análise comparativa e temporal dos valores gerados peloÍndice de Vegetação por Diferença Normalizada (NDVI) para a estação chuvosa nos anos 1992 e 2002.O NDVI é importante em estudos sobre a vegetação existente na superfície terrestre e permiteidentificar possíveis alterações na mesma ao longo do tempo. As cenas utilizadas para a geração dascartas de NDVI são do satélite americano LANDSAT séries 5 e 7. Os resultados demonstraram umpadrão para todos os anos em relação à ocorrência de pixels com valores positivos, especialmente emáreas do entorno e áreas mais centrais da malha urbana, que correspondem a fragmentos devegetação arbórea densa e a áreas verdes públicas existentes no município, respectivamente. Poroutro lado, os valores negativos de pixels concentraram-se a Leste e Noroeste da cidade, onde selocaliza o centro antigo, cuja característica é a alta densidade de construção e baixa presença devegetação arbórea e o Balneário Municipal. Os resultados também mostraram que durante o períodode tempo analisado houve mudanças nos valores de pixels registrados em 1992 e 2002, o que podesignificar um adensamento demográfico e construtivo na cidade e alterações na densidade davegetação existente em sua superfície terrestre, devido, principalmente, ao seu processo de expansãoterritorial no eixo Oeste, Sul e Sudeste.

Les mammites ont un impact économique considérable dans les régions productrices de lait de divers pays, dont le Brésil et la France. Elles constituent la première cause de consommation d’antibiotiques dans les élevages laitiers qui doivent répondre à une forte demande sociétale pour une agriculture consommant moins d’intrants et plus respectueuse de l’environnement et du bien-être animal. Il y a donc une réelle nécessité de trouver des outils alternatifs efficaces pour le contrôle des mammites bovines infectieuses. Ce travail de thèse a eu comme objectif la recherche de souches de bactéries lactiques (BL) ayant des capacités inhibitrices de l´infection mammaire, pouvant être utilisées comme probiotiques mammaires. Pour cela, 278 (165 en France et 113 au Brésil) souches bactériennes ont été isolées à partir de lait et de la superficie et du canal du trayon de vaches laitières et 9 souches non-redondantes de BL ont été identifiées et caractérisées en fonction de leurs propriétés de paroi et de production de composés inhibiteurs avant d´évaluer leurs interactions avec des agents pathogènes responsables de mammites et/ou avec les cellules hôtes dans un modèle de cellules épithéliales mammaires bovines (CEMb). Certaines souches de Lactobacillus brevis e Lactobacillus plantarum ont montré une bonne capacité d’adhésion aux cellules épithéliales ce qui pourrait inhiber l´invasion par Staphylococcus aureus, un pathogène majeur responsable de mammites, et de stimuler la production de cytokines pro- et anti- inflammatoires par les CEMb. D´autres tests d'interaction avec des lignées cellulaires en co- inoculation ont mis en évidence que la souche Lactococcus lactis V7 était capable d´inhiber de manière significative l'invasion des CEMb par Escherichia coli et S. aureus. Le mécanisme exact de cette inhibition n´a pas été élucidé, mais la souche L. lactis V7 a montré des capacités prometteuses en termes de probiotique mammaire, notamment, la capacité de moduler la réponse immunitaire des CEMb infectées par E. coli en intensifiant la réponse inflammatoire. A partir des résultats obtenus au cours de ce travail, on peut suggérer que des souches de L. brevis, L. plantarum et L. lactis V7 présentent des qualités intéressantes pour une possible stratégie de prévention voire de lutte contre la mammite. Ces souches sont en effet capable d'inhiber la croissance et l'adhésion et/ou l'invasion de bactéries pathogènes et de moduler la réponse immunitaire des cellules-hôte, Mastitis causes huge economic losses in the dairy sector both in Brazil and France. They also are the first cause of antibiotic consomption in the dairy farms. There is thus a need for new alternatives to antibiotics to control infectious mastitis. In this thesis work, we isolated 278 (165 in France and 113 in Brazil) bacterial strains from bovine milk and teat canal, and identified 9 non-redundant lactic acid bacteria (LAB) strains that were further tested as potential mammary probiotic candidates. LAB strains were tested for their surface properties and production of inhibitory compounds and then evaluated for their interactions with Staphylococcus aureus and Escherichia coli, two major mastitis pathogens, or with bovine mammary epithelial cells (bMEC), in vitro. Some LAB strains (Lactobacillus brevis e Lactobacillus plantarum) presented inhibitory capacity against S. aureus adhesion and internalisation and were shown to stimulate the production of pro- and anti-inflammatory cytokines in bMEC. Other interaction tests with bMEC showed that Lactococcus lactis V7 was able to significantly inhibit bMEC invasion by Escherichia coli and S. aureus. Although the inhibitory mechanism was not elucidated, Lactococcus lactis V7 showed promising capacities in terms of mammary probiotic potential with, notably, the ability to modulate the immune response of E. coli-infected bMEC by modifying the expression of inflammatory cytokine genes. In this work, several LAB strains were identified in the milk and teat canal microbiota. We showed that L. brevis, L. plantarum and Lactococcus lactis V7 strains had interesting properties for a possible strategy to prevent or treat against mastitis.

The main purpose of this article is to analyze the influence of rural French sociology in the Brazilian academic debate about family farming. The analysis focuses on demonstrating that the main Brazilian authors that influence the theoretical discussion about the issue have strong affiliation to French rural sociology. Inspecific terms, it discusses the public apparatus adopted in France to promote the family-farming model of socioeconomic dimensions with potential to integrate the modernization of agriculture undertaken since World War II. The tendency demonstrated by Brazilian public policies of a productive character to adopta similar orientation signifies excluding from these policies most family farms in the country.; Este artigo tem por objetivo analisar ainfluência da sociologia rural francesa no debate acadêmico brasileiro referente à agricultura familiar. O eixo de análise consiste em demonstrar que os principais autores nacionais que influenciaram a discussão teórica sobre o tema apresentam uma forte filiação à sociologia rural francesa. Em termos específicos discutese o aparato público adotado na França para promover o modelo de agricultura familiar de dimensões socioeconômicas com potencial de se integrar no processo de modernização da agricultura levado a cabo no pós-segunda guerra mundial.A tendência demonstrada pelas políticas públicas brasileiras de caráter produtivode adotar uma orientação semelhante significa excluir dessas políticas a maior parte das unidades agrícolas familiares.

International audience; Fumonisin B1 (FB1) is a secondary metabolite produced mainly by Fusarium verticilioides in several types of foods, particularly corn, which is the basis for composition of feed for several domestic animals. FB1 is particularly toxic to pigs, being the clinical manifestations evident in animals exposed to high concentrations of FB1 in the diet (generally above 30mg/kg). However, there are few studies on the effects of FB1 on pigs fed rations containing low concentrations of fumonisin, which are most probably found under field conditions. The aim of the study was to evaluate the effects of a 28-day exposure of piglets to low levels of FB1 in the feed on the weight gain, feed consumption, organ weights and histological aspects of the spleen, liver, lungs, kidneys and heart. Twenty-four pigs were assigned into 4 experimental groups and fed diets containing 0mg (control), 3.0mg, 6.0mg or 9.0mg FB1/kg diet. The different diets did not affect (P>0.05) the weight gain or the weight of organs examined. There were no macroscopic or histological lesions in the spleen, liver, kidneys and heart. However, histological lesions were found in the lungs from all animals fed rations containing fumonisin, hence indicating that none of the FB1 levels used in the experiment could be considered as safe for piglets. Further studies on the mechanisms of toxic action of FB1 in pigs are needed, particularly under conditions of prolonged exposure to low contamination levels in the diet.; A fumonisina B1 (FB1) é um metabólito secundário produzido principalmente por Fusarium verticilioides em diversos tipos de alimentos, principalmente o milho, o qual constitui a base para composição de rações para várias espécies de animais domésticos. A FB1é particularmente tóxica para suínos, cujas manifestações clínicas são evidentes em animais expostos a altas concentrações de FB1 na ração (em geral, acima de 30mg/kg). No entanto, são escassos os estudos sobre os efeitos da FB1em suínos alimentados com rações contendo baixas concentrações de fumonisinas, as quais são mais prováveis de serem encontradas em condições de campo. O objetivo do estudo foi avaliar os efeitos da exposição de leitões a baixos níveis de FB1 na ração, durante 28 dias, sobre o ganho de peso, consumo de ração, peso relativo de órgãos e aspectos histológicos do baço, fígado, pulmões, rins e coração. Vinte e quatro leitões foram distribuídos em 4 grupos experimentais e alimentados com rações contendo 0mg (controle), 3,0mg, 6,0mg ou 9,0mg FB1/kg de ração. As diferentes dietas não afetaram (P>0,05) o ganho de peso e nem o peso relativo dos órgãos analisados. Não foram constatadas lesões macroscópicas ou histopatológicas no baço, fígado, rins e coração. No entanto, foram observadas lesões histopatológicas nos pulmões de todos os suínos alimentados com rações contaminadas com fumonisinas, indicando que nenhum dos níveis de FB1 usados no experimento poderia ser considerado como seguro para suínos. São necessários novos estudos sobre os mecanismos de ação tóxica da FB1 em suínos, sobretudo em condições de exposição prolongada a baixos níveis de contaminação na ração.

Great droughts of the past (such as 1959, 1976, 1989 or 2003) have had heavy impacts on important socio-economical activities for the economy of the Brittany, such as agriculture. In a climate change context it seems important to evaluate the possible ways of evolution of that risk in this region. These evolutions have been studied by using climate simulations from three IPCC’s scenarios: A1B, A2 and B1. In order to monitor droughts, the methodology used is a soil water balance and the implementation of the evaporation deficit. Results revealed an increase of drought intensity during the 21st century, more specifically in the eastern part of the region. The south coastline would be the most sensitive area in terms of droughts’ intensity and frequency. In that area a similar intensity as the one measured during the 1976 drought, other things being equal, would be frequently reached. Exceptional past droughts could become common in the future, impacting both agriculture and water cycle. This could cause a decreasing in runoff aquifer's levels and force farmers to adapt both crops and cropping methods., RESUME. Les grandes sécheresses du passé (1959, 1976, 1989 ou 2003) ont entrainé des dommages importants sur des activités essentielles pour l’économie de la Bretagne, telles que l’agriculture. Dans un contexte de changement climatique, il apparait donc important d'analyser les évolutions possibles du risque de sécheresse à l’échelle de la région à partir de simulations climatiques du modèle Arpège-Climat pour trois scénarios du GIEC : A1B, A2 et B1. La méthodologie retenue est celle du bilan hydrique et le calcul du déficit d’évaporation. Les résultats montrent une augmentation de l’intensité des sécheresses au cours du 21ème siècle, principalement pour la moitié est de la Bretagne. Le littoral sud serait la région la plus sensible à une augmentation de la fréquence et de l’intensité des sécheresses. En termes d’intensité, on dépasserait ici les valeurs relevées lors de la sécheresse de 1976, toutes choses égales par ailleurs. Ce risque de voir des sécheresses exceptionnelles par le passé devenir communes à moyen terme, impacterait fortement l’agriculture, ainsi que le cycle de l’eau, sur une grande partie de l’année. Cela pourrait entrainer une diminution des écoulements de surface alimentant les nappes phréatiques bretonnes et contraindre les agriculteurs à adapter leurs cultures et leurs pratiques., RESUMO. As grandes secas do passado (1959, 1976, 1989 ou 2003) resultaram em danos significativos às atividades essenciais para a economia da Bretanha, como a agricultura. Por isso, no contexto das mudanças climáticas, parece importante analisar possíveis mudanças quanto ao o risco de seca na escala regional. Essas mudanças são estudadas por meio de simulações climáticas do modelo Arpège-Clima para três cenários do IPCC: A1B, A2 e B1. Para monitorar as secas, a metodologia utilizada é o balanço hídrico e o cálculo do déficit de evaporação. Os resultados mostram um aumento na intensidade das secas durante o século 21, principalmente para a metade oriental da Bretanha. A costa sul seria a região mais sensível para o aumento e a frequência da intensidade das secas. Em termos de intensidade, seriam ultrapassados os valores registrados durante a seca histórica de 1976, inalteradas as circunstâncias. O risco de seca excepcional no passado tornou-se comum em médio prazo e teria um impacto forte sobre a agricultura e o ciclo da água durante uma grande parte do ano. Isso pode causar uma diminuição no escoamento que alimenta o lençol freático na Bretanha e forçar os agricultores a adaptar as suas culturas e práticas agricolas.

National audience; Aiming to contribute to climate-hydrology studies in PARNA Pantanal Ramsar site according to the recommendations of the Ramsar Convention, the present study examined annual series of observed data of rainfall, temperature and fluviometric quota in the period 1971 to 2011 of sub-basin of the Upper Paraguay River. Data were analyzed with tests Mann-Kendall and Linear Regression to identify trends and Pettitt to check ruptures. The following facts were observed: a decline in annual rainfall in the portion extending from the Amazon to the center of the Pantanal biome and an increased of maximum and minimum temperatures at the stations of Cáceres (MT) and Cuiabá (MT). The water level of the rivers located in Ottobacias responsible for the maintenance of the water system of the Ramsar PARNA Pantanal site varied. This study demonstrates the high degree of vulnerability of the Ramsar site PARNA Pantanal to climate variability.; Com o intuito de contribuir com os estudos climato-hidrológicos no sítio Ramsar PARNA Pantanal, conforme as recomendações da Convenção de Ramsar, o presente trabalho analisou séries anuais de dados observados de chuva, temperatura e cotas fluviométricas no período de 1971 a 2011 de estações da sub-bacia do Alto Paraguai. Os dados foram analisados com os testes de Mann-Kendall e Regressão linear para identificação de tendências e Pettitt para verificação de rupturas. Foram constatados diminuição pluviométrica anual na porção que se estende da Amazônia ao centro do Pantanal e aumento das temperaturas máxima e mínima nas estações de Cáceres (MT) e Cuiabá (MT). O nível d' água dos rios localizados nas Ottobacias responsáveis pela manutenção do sistema hídrico do sítio Ramsar PARNA Pantanal variou no período estudado. O estudo demonstra o alto grau de vulnerabilidade do sítio Ramsar PARNA Pantanal à variabilidade do clima.

This article aimed to present the methodological procedures and geoprocessing techniques used for data extraction of thematic cartographic bases or spatial models for the calculation of indices for the evaluation of water sustainability of sugarcane cultivation, applied to the analytical description of four microregions of Goiás State, Brazil: Sudoeste de Goiás, Vale do Rio dos Bois, Quirinópolis and Meia Ponte. The various spatial data in shape format, acquired in secondary sources or elaborate models were introduced in a Geographical Information System (GIS) from computational ArcGIS 10ESRI package. Where by means of simple geoprocessing techniques were done tweaking and/or crossings of spatial data (shapes) in order to obtain data (IUPAP) concerning territorial units of analysis adopted (UTAs microregions) for calculating dimensionless index proposed by System of Indicators for Assessment of the Potential for Water Sustainability and Monitoring of the Sugarcane Cultivation -SISH-Cana (FERRAZ, 2012). The results demonstrate the appropriateness of the techniques used and the level of precision and accuracy of spatial models adopted, whereas the proposed indexes apply to the characterization of the UTAs in strategic planning process, territorial and/or sectoral (water resources; agriculture)., O presente artigo objetivou apresentar os procedimentos metodológicos e as técnicas de geoprocessamento utilizadas para a extração de dados de bases cartográficas temáticas e de modelos hídricos espacializados requeridos para o cálculo de indicadores de sustentabilidade hídrica da cultura canavieira em quatro Microrregiões do Estado de Goiás: Sudoeste de Goiás, Vale do Rio dos Bois, Quirinópolis e Meia Ponte. Os diversos dados espaciais em formato shape, adquiridos de fontes secundárias e de modelos especificamente elaborados para este fim foram introduzidos em um Sistema de Informações Geográficas (SIG), no qual, por meio de técnicas simples de geoprocessamento, foram ajustados e integrados para a obtenção dos dados (grandezas físicas) utilizados para a determinação de indicadores (índices) propostos pelo Sistema de Indicadores para a Avaliação do Potencial de Sustentabilidade Hídrica da Atividade Canavieira - SISH-Cana (FERRAZ, 2012). Os resultados demonstram a pertinência das técnicas utilizadas e do nível de precisão e detalhamento dos modelos espaciais adotados, considerando que os índices aplicam-se para a avaliação de unidades territoriais de analise em nível de microrregião com vistas a planejamentos territoriais e/ou setoriais em nível estratégico.

[Departement_IRSTEA]Territoires [TR1_IRSTEA]DTAM [Axe_IRSTEA]DTAM2-ACPUB [Axe_IRSTEA]DTAM-QT2-ADAPTATION; International audience; Facing the changes in the agricultural sector as well as new growing demands from society in relation to the European countryside, new questions emerge as to the management of the agricultural landscapes. The multiple combination of production with the support of multiple functions is a challenge for present day management. Tools are needed that make it possible to assess how a certain landscape can support in particular cultural and amenity functions, those that directly depend on the public preferences. The objective of this paper is to describe the proposed Landscape Amenity Model (LAM), a landscape amenities evaluation tool developed within the framework of the Integrated Project SEAMLESS. The LAM is based on the calculation of the Index of Function Suitability (IFS) for a given landscape, based on the distance between that landscape and the preferred landscape, as expressed by different users. The paper goes further in applying IFS namely by examining two different approaches for deriving land cover pattern preferences by users, either gathered from questionnaire surveys or expert panels in two case-studies, one in Portugal and another in France, respectively.

National audience; This article aimed to assess the sugarcane expansion process in four microregionsconsidered sugarcane expansion hotspots in the State of Goiás, Brazil, from the use ofindicators proposed by the Indicators System of Sugarcane Water Sustainability Assessment- SISH-Cana (Ferraz, 2012) Thus, it became possible to perform an analytical andcomparative evaluation of the sugarcane expansion process occurred in 2005/2006 to2010201 period, in the following microregions of South of the State of Goiás, Brazil:Sudoeste de Goiás, Vale do Rio dos Bois, Quirinópolis and Meia Ponte, adopted as territorialunits of analysis. The results of the indicators suggest that the proportions of sugarcaneoccupation in microregions studied are still relatively small in relation to the total areas oftheir territories. They also suggest that the sugar-alcohol sector has expanded mainly on themost appropriate areas, precisely those with slope gradients lower than 12 and with soilswith preferential agricultural suitability, where it becomes possible to develop sugarcaneactivity with high technological level. They have also shown that sugarcane expansionprocess is occurring primarily on areas traditionally occupied with agriculture, but alsopointed out the trend of gradual pastures replacement, while the native vegetation removalis relatively small. In relation to the balance between demand and water availability, theresults demonstrated the sugarcane culture still has a high possibility to develop in themicroregions considered.

International audience; The consumer concerns about the origin of their food are rising. In this regard, the traceability acquires increasing relevance in the livestock sector, especially in Brazil, which is the biggest beef exporter in the world. This paper reviews the current knowledge regarding the traceability of the animals feedings using their products, showing the potential markers concerned in the issue. Plant biomarkers (e.g. carotenoids, terpenes and phenolic compounds) and fatty acids are potential tracers in the meat. Geographical origin has been successfully identified by spectroscopy or stable isotopes. In conclusion, each technique has particular indications for own use, so that, probably the future of traceability includes concomitant use of several techniques. Thus, the issue represents a target of high technological impact that needs to be included in the research agenda in Brazil.; A preocupação dos consumidores com a origem dos alimentos é crescente. No setor pecuário, o tema traçabilidade adquire importância cada vez maior, especialmente no Brasil, que é hoje o maior exportador de carne bovina do mundo. Este artigo revisa o conhecimento atual no que diz respeito à traçabilidade da dieta dos animais a partir de seus produtos, apresentando os potenciais traçadores envolvidos na temática. Marcadores de plantas (e.g. carotenóides, terpenos e compostos fenólicos) e ácidos graxos, são potenciais traçadores na carne. Já a origem geográfica tem sido identificada com sucesso através de métodos espectrais ou com base na análise de isótopos estáveis na carne. Em síntese, cada técnica em particular possui indicações próprias de uso de modo que, provavelmente, o futuro da traçabilidade incluirá a utilização concomitante de diversas técnicas. O tema, portanto, constitui-se em objeto de alto impacto tecnológico que necessita ser incluído na pauta de pesquisa no Brasil.

This paper discusses the transformations of the environmental issue between 1992 (Rio Conference) and 2012 (Rio+20 Conference) and highlights the controversies and deadlocks of this question, as well as its challenges. Focusing on climatic changes and employing the notion of complexity to guides the analysis and the comprehension of the processes, the question is contextualized within the international scenario. In this debate, emphasis is given to the positions and trends of different countries in terms of technical and political changes leading to a shift from mitigation to adaptation. The conclusion seems to point to the adoption of adaptation and environmental management measures at local scale as the inevitable pathway to face a situation in which today many place little hope for a diplomatic political solution.; O artigo discute as transformações da temática ambiental entre 1992 (Conferência do Rio) e 2012 (Conferência Rio + 20) destacando as controvérsias, impasses e desafios dessa problemática enfocando as mudanças climáticas, fundamentados em abordagem comparativa e na noção de complexidade geopolítica, a qual norteia as análises e a compreensão dos processos. Assim, contextualiza-se essa questão no cenário internacional, enfatizando a posição e tendências dos distintos países, com relação às mudanças técnico- -políticas da mitigação para a adaptação. Nesse debate assumimos que se tornou inevitável a adoção de medidas de adaptação e de gestão ambiental, no âmbito local, para enfrentar uma situação dominada pelo impasse político e diplomático.

With the purpose of increase the breeding of Black Belly sheep breed at the experimental station of the Institut Scientifique de Recherche Agronomique (INRA), Bourges, France, thirty-two Black Belly sheep were super ovulated with swine FSH on the last three days of a progesterone treatment. After surgical collect 264 embryos transferable were recovered (8.2 ± 6.0/ donor) and 232 were transferred to 88 multiparous Romane sheep receptors and 23 nulliparous Suffolk sheep. Birth rate and survival rate were 83.6 and 63% respectively, though the results form multiparous Romane sheep receptors were better than from nulliparous Suffolk sheep. The ovulations number, transferred embryos and development stage had an effect on embryo survival rate. The best birth and embryo survival rates were from receptors that had more than two ovulations and had two embryos implanted at the stage of blastocyst.; Visando ao aumento do plantel de ovinos da raça Black Belly na estação experimental do Institut Scientifique de Recherche Agronomique (INRA) de Bourges, França, foram utilizadas 32 ovelhas da raça Black Belly superovuladas com FSH suíno nos últimos três dias de tratamento progestágeno de 14 dias. Após coleta cirúrgica, obtiveram-se 264 embriões transferíveis (8,2 ± 6,0/doadoras), sendo transferidos 232 a 88 receptoras da raça Romane pluríparas e 23 da raça Suffolk nulíparas. As taxas de parição e de sobrevivência embrionária foram 83,6 e 63%, respectivamente, sendo os melhores resultados observados em receptoras da raça Romane pluríparas do que nas nulíparas da raça Suffolk. O número de ovulações, de embriões transferidos e o estádio de desenvolvimento embrionário causaram efeito sobre a taxa de sobrevivência embrionária. As melhores taxas de parição e de sobrevivência embrionária foram obtidas de receptoras com mais de duas ovulações que receberam dois embriões no estádio de blastocisto.

Soil organic matter (SOM) is responsible for soil fertility, nutrient cycling and structure stability and is closely related with soil aggregation. However, the relationship between aggregate size classes in the SOM dynamics is unclear, resulting in SOM accumulation or loss due to soil land use and management. This study aimed to evaluate the amount of carbon (C) in soil aggregates under four uses and management: native Cerrado (CE-savannah vegetation), no-tillage (NT), conventional tillage (SPC) and pasture (PA). The study areas are located in Rio Verde (GO) where the soil was classified as kaolinitic clayey Oxisol. The soil layers 0-5, 5-10 and 10-20 cm were sampled (n=6) in February 2007, and the amount of water-stable macroaggregates (> 2.0 mm), mesoaggregates (> 0.25 and < 2.00 mm) and microaggregates (> 0.05 and < 0.25 mm) were determined, as well as the mean weight diameter (MWD) and mean geometric diameter (MGD), and the C levels in the soil aggregate classes. Macroaggregates were predominant in the soil evaluated, with higher quantities in CE and PA compared NT and SPC soils, indicating a negative effect of soil cultivation on macroaggregate conservation. However, the soil aggregate C levels in the 0-20 cm layer were higher in CE and SPD than in PA and SPC soils, suggesting that the absence of tillage and maintenance of crop residues on the soil drives C accumulation. This shows that macroaggregates and mesoaggregates were more sensitive to soil use and management than microaggregates. The similarities of aggregation in PA and CE soils, although with lower C levels in PA suggested different aggregation dynamics, requiring further research., A matéria orgânica do solo (MOS) é responsável pela fertilidade, ciclagem de nutrientes e estabilidade da estrutura, possuindo estreita relação com a agregação do solo. No entanto, ainda não é clara a relação entre as classes de agregados na dinâmica de acúmulo ou perda de MOS em função do uso e manejo do solo. Este trabalho teve como objetivo avaliar os teores de carbono (C) em agregados do solo sob quatro usos e manejos: Cerrado nativo (CE), sistema plantio direto (SPD), sistema plantio convencional (SPC) e pastagem (PA). As áreas de estudo estão localizadas no município de Rio Verde (GO), em solo classificado como Latossolo Vermelho distrófico de textura argilosa. Em amostras de solo coletadas em fevereiro de 2007 nas camadas de 0-5, 5-10 e 10-20 cm de profundidade, foram determinados: a quantidade de macroagregados (maiores que 2,0 mm), mesoagregados (maiores que 0,25 e menores que 2,00 mm) e microagregados (maiores que 0,05 e menores que 0,25 mm) estáveis em água, os índices de agregação diâmetro médio ponderado (DMP) e geométrico (DMG) e os teores de C nas classes de agregados estabelecidas. No solo avaliado observou-se predominância de macroagregados, com maior quantidade sob CE e PA, em comparação ao solo sob SPD e SPC, indicando efeito negativo do cultivo do solo na conservação de macroagregados. Contudo, os teores de C nos agregados do solo na camada de 0-20 cm foram maiores no CE e SPD em relação a PA e SPC, sugerindo que o não revolvimento e a manutenção dos resíduos culturais na superfície do solo favorecem o acúmulo de C. Com isso, foi verificado que os macro e mesoagregados podem ser mais sensíveis ao tipo de uso e manejo do solo, quando comparados aos microagregados. A agregação do solo sob PA é semelhante à do CE, embora com menores teores de C, sugerindo dinâmica de agregação diferenciada, o que merece a atenção de novas pesquisas.

The Geographical Indications (GIs) are tools for valorization of goods increasingly used worldwide. This theme is a persistent agenda of the international trade negotiations. The regulation of GIs is one of the most prominent themes in the discussions relative to the organization of the global food system, especially because it involves issues such as intellectual property rights and market access. Opposed to a process of food production and consumption homogenization, the GIs seek to prize the diversity and singularity of products embedded in particular territories, highlighting the intangible assets as know-how, tradition, customs, practices of production etc. Nevertheless, it is a generic concept that makes sense to different contexts and social actors, including those outside of territory. In each project of the geographical indication is conformed to an heterogeneous sociotechnical network, where the concepts of quality are negotiated and different values are confronted. The institutionalization of grades and standards that enable the actors to transact is the result of this negotiation process in which commitments between heteroclite values are constructed. In the wine world, the geographical indications were for a long time, a concept which was associated almost exclusively with a style of production that was based in the prize of distinctive terroirs, through of institutionalization of rarity and traditional methods of viticulture and winemaking. However, the current changes in the wine global market related with the entrance of new actors and new qualitative conventions began to change the lives of terroirs and the concept of geographical indication. The adaptation of GI's in a new context has showed how this mechanism can be molded to different purposes. In this sense has showed how this tool can be molded with an instrument of qualification, in the wine sector where manifest a double process of institutionalization. First, the IGs have incited the valorization of territories and their identities, creating in some cases barriers to innovations that may reflect risk to the product uniqueness. Second, we are witnessing a process of sectorial appropriation where they are adjusted to serve as a catalyst for organizational and technical innovations consider necessary to the producers reacting to the loss of competitiveness in national and international markets. Thus, within a context of hybridization of competitive strategies in the wine market, these projects have reconciled conceptual models once antagonistic. For this to be viable, rather than reconcile tradition and innovation, the IGs are creating new commitments (compromissos) between evaluative principles (quality definitions), which manifests itself in a sequence of changes in production practices that range from the choice of varieties of grape until the definition of the methods of winemaking. The present research involved the study of seven different IGs in Brazil (Vale dos Vinhedos, Pinto Bandeira, Monte Belo do Sul, Farroupilha, Garibaldi) and France (Beaujolais, Languedoc), where it was done through semi-structured interviews, observation and documental analysis.; Les indications géographiques (IG) sont un instrument de plus en plus utilisé dans le monde entier. Sujet fréquent des négociations de commerce international, la régulation des IG est un des thèmes les plus importants dans les discussions concernant l'organisation du système agroalimentaire mondial, dans la mesure où il concerne un ensemble de questions autour des droits de propriété intellectuelle et de l'accès aux marchés. Opposé à un processus de standardisation de la production et de la consommation alimentaire, les IG cherchent à valoriser la diversité et l'originalité de produits ancrés dans des territoires spécifiques, mettant l'accent sur les biens immatériels (savoir-faire, tradition, habitudes, façon de produire etc.). Pourtant, il s'agit d'un concept générique qui peut être utilisé dans différents contextes et par des acteurs sociaux les plus divers, y compris pour ceux qui sont dehors du territoire. Chaque projet d'indication géographique est composé par un réseau sociotechnique hétérogène, au sein duquel sont négociées différentes conceptions de qualité et où des valeurs sont en conflit permanent. L'institutionnalisation des règles et des modes de production qui permettent aux acteurs d'échanger est le résultat de ce processus de négociation où des compromis entre des valeurs différentes sont constitués. Dans le monde des vins, les indications géographiques ont été pendant longtemps un concept qui était presque exclusivement lié à un modèle de production lié à la valorisation de terroirs distincts, à l'institutionnalisation de la rareté et à des méthodes traditionnelles de viticulture et de vinification. Cependant, les changements en cours sur le marché mondial, associés à l'entrée en scène de nouveaux acteurs et de nouvelles conventions qualitatives, ont commencé à transfigurer la vie des terroirs et la notion même d'indication géographique. Son adaptation aux nouveaux enjeux économiques a révélé la façon dont ce mécanisme peut être adapaté à différents objectifs. Dans cette thèse, nous révèlons que le développement récent de cet instrument de qualification dans le secteur vitivinicole exprime un double processus d'institutionnalisation. D'un côté, les IG ont incité la valorisation des territoires et de leur identité, avec, dans certains cas, la création d'obstacles aux innovations qui pourraient mettre en péril la typicité des produits. De l'autre, les IG ont été ajustées, dans le cadre d'un processus d'appropriation sectorielle, pour permettre des innovations techniques et organisationnelles jugées nécessaires pour que les producteurs puissent réagir à la perte de compétitivité sur les marchés nationaux et internationaux. Ainsi, dans un contexte d'hybridation des stratégies compétitives sur le marché du vin, les projets concilient des modèles conceptuels autrefois antagonistes. Pour cela, plus que concilier tradition et innovation, les IG créent des nouveaux compromis entre des principes de valorisation (définitions de qualité), qui se matérialisent dans un ensemble de changements des pratiques productives impliquant notamment le choix des cépages ou la définition des méthodes de vinification parmi d'autres composants. Nous avons étudié sept IG distinctes au Brésil (Vale dos Vinhedos, Pinto Bandeira, Monte Belo Sul, Farroupilha, Garribaldi) et en France (Beaujolais, Languedoc) sur la base d'entretiens semi-directifs, d'observation et d'analyse documentaire.

http://www.dsr.inpe.br/sbsr2011/files/p0947.pdfhttp://www.dsr.inpe.br/sbsr2011/files/p0947.pdf; International audience; The aim of this study is to show the land-cover changes after the construction of a hydroelectric dam in the central south state of Mato Grosso (Brazil) and the impact of this from an environmental point of view. With the use of satellite imagery it is possible to show which areas of vegetation flood and those which are always clear of the water: for example: cerrado, pasture land, forest, culture. The multi temporal study permits us to evaluate and quantify the change in land cover in the flood plain after the creation of the dam. This study presents the evolution of the land use in the flood plain during the 17 years, before and after the construction of the dam (between 1992 and 2009).To allow comparisons and interpretations of data, the images used were provided by the sensor Landsat-TM with atmospheric and geometric corrections. The useful agricultural land on the floodplain increased more than 100%, in 17 years. The areas of cerrado or forest which became arable or pasture formed 22.5 % of the total territory. The implantation of the dam and the land-use changes which resulted have had and will continue to have major repercussions on the environmental and territorial organisation.

A conversão de áreas nativas com o corte e queima de vegetação seguida do cultivo do solo resultam em mudanças na dinâmica da matéria orgânica do solo, com alterações nas emissões dos gases causadores de efeito estufa (GEE: CO2, CH4 e N2O) da biosfera para a atmosfera, que causam a elevação da temperatura média e, consequentemente, as mudanças climáticas globais. O objetivo deste estudo foi verificar as relações entre os fluxos de CO2, CH4 e N2O com a umidade, biomassa microbiana e as formas inorgânicas de N no solo com diferentes usos das terras no bioma Cerrado (Rio Verde, Goiás). O clima da região é do tipo Aw (Köppen-Geiger), e o solo foi classificado como Latossolo Vermelho distrófico caulinítico textura argilosa com vegetação original de Cerradão. O delineamento experimental foi inteiramente casualizado (DIC), com quatro tratamentos (áreas): vegetação nativa - Cerradão (CE); pastagem (PA) de braquiária, semeadura convencional (SC) de soja; e semeadura direta (SD) de milho sucedido por milheto. As emissões anuais de CO2 e N2O não mostraram diferenças significativas entre os tratamentos; isso ocorreu devido à elevada variação nos fluxos dos gases em decorrência da sazonalidade no clima, com as menores emissões observadas durante o inverno, devido à ausência da umidade do solo. A média na emissão de CO2 foi de 108,9 ± 85,6 mg m-2 h-1 , e para o N2O, de 13,5 ± 7,6 µg m-2 h-1. Os fluxos de CH4 apresentaram diferenças significativas somente para a pastagem, com emissão de 32 µg m-2 h-1 , enquanto nas demais áreas foram observados influxos entre 46 e 15 µg m-2 h-1 . Com os resultados das correlações, pode-se verificar que a umidade foi a variável do solo que apresentou maior correlação com o fluxo dos três gases de efeito estufa. O teor de N-NO3- e as emissões de CO2 mostraram correlações para todas as áreas. Quando consideradas as correlações para todos os tratamentos conjuntamente, verificou-se que os fluxos dos três gases apresentaram correlações significativas com os teores de C e N-microbiano. Contudo, a relação Cmicro:Nmicro não mostrou correlação significativa com o fluxo dos gases de efeito estufa. A pastagem foi a única situação em que os fluxos de CO2 e N2O apresentaram correlação com as quantidades de N-inorgânico. Os resultados sugerem que os fluxos dos GEE são dependentes do regime pluvial no bioma Cerrado, principalmente nas áreas cultivadas que recebem altas doses de fertilizantes para o aumento da produtividade. The conversion of native forests by cutting and burning into farming areas leads to alterations in the dynamics of soil organic matter, with changes in emissions of greenhouse gases (GHGs: CO2, CH4 and N2O) from the biosphere to the atmosphere. These cause an average temperature rise and, consequently, global climate change. The aim of this study was to examine relationships between the fluxes of CO2, CH4 and N2O with moisture, microbial biomass and inorganic N forms in soil with different land uses in the Cerrado biome (Rio Verde county, State of Goias - Brazil). The climate (Köppen-Geiger) was classified as Aw and the soil as Latossolo Vermelho distrófico caulinítico / a clayey kaolinitic Oxisol under original Cerrado (Brazilian savanna) vegetation. The experiment was arranged in a completely randomized design (CRD) with four treatments (areas): Native vegetation - Cerrado (CE); brachiaria pasture (PA); soybean in conventional tillage (SC) and no-tillage (NT) corn followed by millet. No significant differences in annual CO2 and N2O emissions were observed between treatments. This can be explained by the variability of gas fluxes due to climate seasonality, with lower emissions in the winter due to low soil moisture. Mean emissions of CO2 were 108.9 ± 85.6 mg m-2 h-1 , and of N2O 13.5 ± 7.6 mg m-2 h-1 . For CH4 significant differences in the fluxes were only observed in pasture (32 mg m-2 h-1 ), while in the other areas inflows between 46 and 15 mg m-2 h-1 were observed. The GHG fluxes showed close correlation with soil moisture. The N-NO3- emissions were significantly correlated with CO2-emissions in all areas. Considering all treatments together, the three GHG fluxes were correlated with the microbial C and N contents. However, the Cmicro: Nmicro ratio was not significantly correlated with the GHG flux. Only for pasture the CO2 and N2O fluxes were correlated with the content of soil inorganic-N. Results suggested that the GHG fluxes in the Cerrado are related to rainfall, mainly in farming areas treated with high fertilizer doses to increase productivity.

The reports of rainfall data can be altered for technical or human reasons. This study presents an approach to detect erroneous raingauges data in Legal Brazilian Amazon over the period (1998-2009). We examine the precipitation data from a target station with those of nearby stations belonging to a buffer. This buffer of 260 km is determined from the decorrelation of rainfall data versus the distance between the raingauges. Differences normalized of nine statistical criteria of a given station with the average of these criteria of nearby raingauges are calculated to build a risk index. This risk index shows a gloal quality of rainfall data used., Os relatórios dos dados de precipitação podem ser alterados por razões técnicas ou humanas. Esse estudo apresenta uma metodologia para detectar dados errôneos nos medidores na Amazônia Legal brasileira ao longo do período (1998-2009). Examinamos os dados de precipitação de uma estação com os de estações vizinhas pertencentes a um buffer. Esse buffer de 260 km é determinado a partir da decorrelação dos dados de precipitação com base na distância entre os pluviômetros. As diferenças normalizadas entre nove critérios estatísticos de uma estação e a média desses critérios das estações próximas são calculadas para construir um índice de risco. Esse índice de risco representa a qualidade global dos dados pluviométricos utilizados.
