Caracterização hidroquímica dos sistemas aquíferos Serra Geral e Guarani da sub-bacia do Rio Pardo e municípios adjacentes, no sudoeste do estado de São Paulo

The main purpose of this work is to evaluate the chemical composition of the groundwaters from Guarani Aquifer System and Serra Geral Aquifer System in the Rio Pardo basin, located at the southwestern of São Paulo state. To the hydrochemical characterization, physicalchemical analyses from 32 sampled wells were used. These results were plotted in Piper diagrams allowing the classification of groundwater as calcium or calcium-magnesium bicarbonate type and sodium bicarbonate type for both aquifer systems. Distribution of hydrochemical facies over the study area was obtained using Stiff diagrams. The groundwater can be classified, representing in this sequence its hydrochemical evolution. The recognized mechanisms responsible for groundwater evolution are dissolution of minerals magnesium, such as olivine, present in the basalt, dissolution of feldspars and removal of the carbonate cement of the sandstones mineral framework. Ionic exchange may represent an important processes in the groundwater evolution, responsible for the increase in the sodium concentration and decrease of calcium

A institucionalização da agricultura familiar no mercosul

The Mercosul project, signed in 1991, represents the union of a political project, characterized by a democratic agreement among its members, with an economical project characterized by the trade liberalization among its regional members and among these with the global economy. So, it was constituted, with the aim to expand the national trades by the integration, to increase the economic development process with social justice. However, the Mercosul follows the historical trajectory of Latin America integration, characterized by models that aimed the economical development from the strengthening of the industry. According to that, the Mercosul politics are priority for economic issues, focused in the industrialization and trade relations, giving less priority to the social demands. In opposition to such ideas, in 2004 was created the Especialized Meeting about Family Farm (Reunião Especializada sobre Agricultura Familiar - REAF) in the Mercosul, that aim to strengthen the public policies of the sector, to promote the commercialization of the family farm products in the region. So, the family farm, a sector historically marginalized from the integration projects, it is institutionalized in the Mercosul. In that way, the aim of this research is to discuss the reasons that leaded to the family farm institutionalization, and also to analyze the advances and problems of the Especialized Meeting about Family Farm

A importância da reserva legal para a preservação da fauna e flora existentes nas propriedades rurais de Botucatu

The main objective of this study was elaborating a diagnosis of technical conditions of Legal Reserves situation on the rural properties in Botucatu. In addition, considering the characteristics of fauna and flora and the economic aspects of these areas, it was presented alternatives to encourage the correct implantation and the effective preservation of the Legal Reserves. Because these areas contribute to the maintenance of local biodiversity and to availability of environmental services essential for all living creatures. In this study it was observed the presence of native vegetation in 13% of the rural properties’ areas in Botucatu, it is therefore necessary the recovery (reforestation) of 7% of all the rural properties’ areas, to be achieved the 20% of native vegetation (minimum area to be preserved as Legal Reserve, as disposed in Federal Law nº 12.651/12) on rural properties. A viable and significant alternative for recovery these areas, reinforced by the new forestry law, is the practice of sustainable management, that must be carried in harmony with conventional farming practices existing in the remaining areas of rural properties

Análise das propriedades da madeira de estrutura de telhado após a ocorrência de um incêndio

The present study evaluated the mechanical properties of pieces of wood coming from the roof structure of a residence subject fire in the rural area of Itapeva/SP. The structure was built 25 years ago using wooden beams of the species Guarucaia (Peltophorum vogelianum), where the specimens were removed. The research methodology included qualitative evaluation of the samples, estimating the layer pyrolysis and carbonization of the wood, measuring of density and mechanical tests of compression parallel to grain, tension parallel to grain and shear. The mechanical properties of wood were analytically correlated with the layers carbonization and pyrolysis that are influenced by the temperature and time of fire; these values were estimated at 1000 °C and two hours for the case in question. The results indicate that the strength properties of degraded wood are different from a healthy wood. The level of thermodegradation, in general, can be measured by density, result in weight loss due to decomposition of the wooden components.

Agroecologia e redes sociais: análise da participação intersetorial. Um estudo a partir da rede de agroecologia Mantiqueira-Mogiana

O objetivo desse trabalho foi discutir a participação das diferentes instituições integrantes da Rede de Agroecologia Mantiqueira-Mogiana, organização social com enfoque no desenvolvimento comunitário coordenada pela Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), que trata da construção coletiva do aprendizado e da troca de experiências e intercâmbio de tecnologias em Agroecologia. Para tanto, foi proposto que as instituições participantes da Rede de Agroecologia respondessem um questionário que abrangia tópicos acerca da participação de tais instituições bem como de estruturação e gestão da Rede. Tendo o estudo tratado da participação das instituições, foram contatados os profissionais dessas organizações envolvidos diretamente com as atividades da Rede, por ser de conhecimento prévio que tais instituições são representadas no projeto por um determinado profissional com maior identificação pessoal com o campo da Agroecologia. Tais opiniões foram posteriormente analisadas enquanto representativas das instituições as quais esses profissionais estão vinculados. Os dados obtidos revelaram a necessidade de um acordo formal entre a Empresa Brasileira de Pesquisa Agropecuária e as instituições participantes do projeto, o que permitiria que os profissionais pudessem participar de forma mais efetiva das atividades da Rede de Agroecologia, integrando as atividades do Colegiado Gestor com as atividades das instituições as quais esses profissionais são vinculados. Foi possível observar também que para que os objetivos de uma determinada rede de desenvolvimento comunitário sejam atingidos é necessário que estes estejam em consonância com as motivações que as instituições parceiras apresentam para participar de tal rede. Dessa forma, é possível congregar esforços de todas as partes para que o objetivo coletivo seja atingido.

A geografia agrária brasileira: dinâmica, variada e complexa

This paper is a contribution to the debate on the methodological issues surrounding the Land Geography, demonstrating why the Brazilian Agrarian Geography is dynamic, varied and complex. It was chosen as the theme of Research Groups in Geography Agrarian present in Directory Groups CNPq and they held on a characterization considering: home institution, location, year of training, Group name, words and lines of research. The survey allowed the treatment of 70 groups in 2009 had the agrarian geography, agriculture, rural development, rural, rural areas, organization of space and rural development as guiding their research and performances. The analysis of the research lines identifi ed groups concerned with economic, political, ecological, demographic and cultural, and also found concerns with farmers, with their production and the functioning of the agricultural system, being thus, the set of raised lines one can say that there is signifi cant diversity in themes, which reinforces the hypothesis of dynamism, variety and complexity of studies on agriculture today.

Educação ambiental nos anos finais do ensino fundamental em uma escola do campo: uma análise a partir do projeto político pedagógico

Environmental education (EE), a critical component to face the environmental crisis, must be present in formal education in a continuous, permanent and transversal way. Studies show, however, that EE occurs, often, in a sporadic and discontinuous way, and that it is mainly linked to Sciences. The objective of this study was to investigate the inclusion of environmental subjects in the Political Pedagogical Project (PPP) of a rural school, in Araraquara, SP. Through documentary analysis of the PPP, proposals for the Environmental Education for the last years of elementary education were examined. The results allowed the understanding, in a complex and contextualized way, of aspects related to the presence of environmental subjects in the school curriculum. They reveal that the suggestion of working with Environment attend the recommendations of the conference of Tbilisi and of Brazilian National Curriculum (PCN).

O programa territórios de cidadania no norte pioneiro paranaense: premissas processos e perspectivas

A abordagem territorial do desenvolvimento tornou-se um referencial importante para a elaboração de políticas públicas de desenvolvimento rural. No Brasil, a Secretaria de Desenvolvimento Territorial, criada em 2003 e vinculada ao Ministério do Desenvolvimento Agrário, o adotou estrategicamente. O Programa Nacional de Desenvolvimento Sustentável dos Territórios Rurais (Pronat), lançado em 2003, prevê a execução de um conjunto de ações voltadas a municípios rurais articulados territorialmente. Em 2008, ocorreu a implantação do Programa Territórios da Cidadania, desdobramento do Pronat e política de desenvolvimento rural para dinamizar territórios economicamente deprimidos. A gestão decisória compartilhada entre Estado e sociedade é uma das premissas e objetivos do Programa. No estado do Paraná, o Projeto de Inclusão Social e Desenvolvimento Rural Sustentável converge com as políticas territoriais estabelecidas na esfera federal, tanto em termos de conteúdo como de procedimentos. A análise da constituição do Território Integração Norte Pioneiro (PR) fundamenta o argumento de que a formulação do Pronat, e do Programa Territórios da Cidadania, tem como um de seus objetivos centrais a constituição de uma esfera decisória microrregional que atue nas questões rurais, priorizando-se a descentralização das atribuições no que concerne ao desenvolvimento rural.

Inovação tecnológica de boas práticas agrícolas e a informática na gestão agropecuária

This study aims to develop innovative proposals for production agriculture management and plans to build a participatory model, through the digital inclusion of members of the family farm gathered in a cooperative venture seeking to establish new environmental management efficiency for household production. The first part of the hypothesis assumes that a major obstacle to the insertion of small family farms into the markets is skilled labor, human capital. A training model has been developed for traceability and tracking activities on family farms, based on the atemoya culture. The second hypothesis predicts that it is possible to create a model that is scientifically supported by widely accepted rules derived from GlobalGAP standard certification, a global benchmark for good agricultural practices. Using these rules the model seeks to achieve the traceability of agricultural products and operations from the preservation of identity information within the production chain. The results obtained by the computerized system confirmed the presented hypotheses by demonstrating that technological innovation through intensive communication and information technologies education as well as other associated forms are important drivers of regional development, especially if implemented through a digital inclusion project using the state program Infocentros Access São Paulo.

Estrutura Institucional da Sustentabilidade: Panorama Comparativo Preliminar Brasil - França.

A sustentabilidade vem sendo perseguida em todos os segmentos da economia tanto dos países desenvolvidos quanto em desenvolvimento. Especificamente no que diz respeito ao setor rural destes países não poderia ser diferente. O presente trabalho se propõe a analisar e comparar o Brasil e a França em termos das principais semelhanças e diferenças nas suas estruturas institucionais voltadas para a promoção do desenvolvimento rural sustentável. Para tanto, foram utilizados os métodos Dedutivo e Indutivo. Verificou-se que as estruturas institucionais de ambos os países são relativamente semelhantes, muito embora haja especificidades relacionadas às distintas realidades rurais destes países em termos de atividades agropecuárias, florestais, propriedades rurais, dentre outros aspectos. O desenvolvimento rural sustentável desempenha, assim, um papel importante nas políticas nacionais, da França e do Brasil, sendo que a agropecuária, o meio ambiente, as energias, o turismo, a educação e a pesquisa são as principais áreas de sustentabilidade em ambos os países. Pode-se observar que, em geral, um Ministério francês responsabiliza-se, em se tratando de temas vinculados ao desenvolvimento rural sustentável, por uma área de ação mais ampla e menos precisa comparativamente a um Ministério brasileiro. Por fim, alguns temas associados ao tema do desenvolvimento rural sustentável são exclusivamente observados nos Ministérios brasileiros, tais como proteção das florestais tropicais, povos indígenas e biocombustíveis.

Construção e validação de um túnel de vento para ensaios de estimativa da deriva em pulverizações agrícolas

The aim of this study was to build and validate a low cost reduced-scale wind tunnel for drift evaluation on pesticide application technology. The work was carried out at the NEMPA - Núcleo de Ensaio de Máquinas e Pneus Agroflorestais (NEMPA), FCA/UNESP, Departamento de Engenharia Rural, Botucatu/SP, Brazil. The wind tunnel main characteristics were an open circuit and a closed working section with a fan blowing air into the tunnel. Screens were fitted downstream after the fan in order to stabilize the air flow on the working section. The tunnel was built with 3.0 mm eucalyptus hardboard, with a total length of 4.8 m and a squared section of 0.56 m. The air flow was provided by a 180 W axial fan. The system was adjusted and calibrated to provide a laminar and stable flow at 2.0 m s-1. Validation studies were carried out by using a Teejet XR 8003 flat fan nozzle at 200 kPa (medium droplets) to apply a spray solutions containing water plus a food dye (Blue FDC) at 0,6% m v-1 mixed with two adjuvants: a polymer based anti drift formulation at 0,06% m v-1 and a sodium lauryl ether sulfate based surfactant at 0,2% v v-1. After a 10-second application the drift was collected on nylon strips transversally fixed along the tunnel at different distances from the nozzle and different high from the bottom part of the tunnel. Drift deposits were evaluated by spectrophotometry. The wind tunnel had low levels of turbulence and high repeatability of the data, which means that the flow was uniform and able to be used for carrying out measures to estimate drift. The validation results showed that the tunnel was effective to enable comparative drift measurements on the spray solution used in this work making possible the evaluation of drift risk potential under those spray technologies. The use of an adjuvant based on a polymer reduced the amount of drift from the nozzle compared to the surfactant.

Ocorrências e usos do Tucumã (astrocaryum vulgare mart) em comunidades ribeirinhas, quilombolas e de agricultores tradicionais no município de Irituia, Pará

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.
