Agricultura de baixa emissão de carbono: uma investigação sobre financiamento e potenciais benefícios

O objetivo geral do presente trabalho é comprovar a hipótese de que é possível proporcionar proteção de renda ao produtor rural e adição de carbono no solo a partir da análise de dados secundários. Além disso, pretende-se investigar a possibilidade de facilitar a concessão de crédito em projetos que aplicam técnicas do Plano ABC sob a ótica de quem atua diretamente no atendimento aos produtores rurais no Banco do Brasil; analisar se está havendo um acompanhamento satisfatório do resultado positivo do crédito rural aplicado através do Programa ABC; e investigar formas de converter as emissões de GEE evitadas e o carbono armazenado no solo em valor agregado para o produtor tomador do crédito do Programa ABC. Para atingir o objetivo geral, foram analisados dados secundários obtidos de SENAR; EMBRAPA; IMEA (2014) e dados fornecidos de um experimento conduzido por pesquisadores da unidade da EMBRAPA. A análise dos resultados de SENAR; EMBRAPA; IMEA (2014) mostrou que apesar de ter ocorrido o efeito da proteção da renda no período de uma safra, 2009/2010, não se pode confirmar a hipótese de que as tecnologias ABC aplicadas na unidade produtiva são capazes de proporcionar proteção de renda ao produtor rural ao longo de vários ciclos produtivos. A partir dos resultados fornecidos pela EMBRAPA, não se pode confirmar a hipótese de que as tecnologias ABC aplicadas nas propriedades estudas são capazes de proporcionar adição de carbono ao solo. No entanto, diversos estudos indicam que há ganhos de estoques de carbono em solos bem manejados. O crédito do Programa ABC merece tratamento diferenciado junto as instituições financeiras, necessita também de acompanhamento, após a liberação do crédito, que vai além da simples fiscalização que verifica o andamento dos empreendimentos, mas mensurar se está havendo redução das emissões e captura de carbono nas áreas financiadas. E por último, o setor financeiro e os demais agentes das cadeias produtivas devem proporcionar valor agregado aos produtores que aplicam as boas práticas agronômicas do Plano ABC.

Economia solidária e relações de gênero na agricultura familiar: o caso do grupo produtivo mulheres decididas a vencer

The Women s experiences in the private sphere under the work s field changes the family relationship allowing them more freedom, autonomy and independence. The inequalities, socially built, homemade women s obligations results in discrimination, difficult to insert and recovery on female s job in a job s market, including low salary if compared with men s and difficult to services access in addiction a difficult daily life and in domestic sphere. The women s organisation in productive groups or economically solidary enterprises (ESE) torn possible the social economically organisations and politicians to promote deep changes in a domestically e socially relationship, positioning, for example, women s in publics areas and in the rout of emancipation. The objective of this search are understand men and women relationship in the family agriculture s field starts insert women in economically solidary enterprises (ESE) on Mulunguzinho s settlement (Mossoró/RN). The theoretical framework is inspirited Economical Solidary concept kind division s job and women s empowerment. This search had a qualitative character and exploration through case s study on Mulheres decididas a vencer s group. The secondary information was create through theoretical framework and information collected through semi-structured interviews based in interviews applied for women and yours respective husbands by criterion for women participation on productive activities of beekeeping culture of goat and sheep.

This finding confirm a different aspect not economical in solidary economy overcoming the monetary value in associative relationship observing principally individuals well-being and the concern with the form of reproduction this way of life in the associated

Caracterização de novos isolados de Bacillus thuringiensis para o controle de importantes insetos-praga da agricultura

A bactéria Bacillus thuringiensis Berliner produz um corpo de inclusão paraesporal (cristal) de natureza proteica, formado durante a esporulação, que atua de forma eficiente no controle de insetos-praga de culturas economicamente importantes. Esse cristal é constituído de proteínas Cry, que são codificadas pelos genes cry; um isolado pode ser caracterizado pelo conteúdo de genes cry que apresenta. Visando caracterizar novos isolados no combate de insetos-praga pertencentes às ordens Lepidoptera e Coleoptera, 76 isolados bacterianos foram analisados molecularmente e tiveram seu potencial de controle avaliado por meio de bioensaios com larvas de Spodoptera frugiperda (J.E. Smith), Sphenophorus levis Vaurie e Tenebrio molitor Linnaeus. As análises moleculares indicaram 11 isolados (14,5% da coleção), contendo genes lepidóptero-específicos e 17 (22,37%) com genes coleóptero-específicos. As análises de patogenicidade revelaram dois isolados com alto potencial de controle para lagartas de S. frugiperda, um para larvas de S. levis e seis prejudiciais ao desenvolvimento das larvas de T. molitor. Esses isolados de B. thuringiensis podem ser promissores no controle biológico das referidas pragas.

Variabilidade espacial de atributos do solo para adoção do sistema de agricultura de precisão na cultura de cana-de-açúcar

O objetivo do presente trabalho foi avaliar a variabilidade espacial de atributos de Latossolos sob cultivo de cana-de-açúcar na região de Jaboticabal (SP). Foram feitas amostragens do solo a intervalos regulares de 50 m, em uma área de 90 ha, nas profundidades de 0,00-0,20 e 0,60-0,80 m para determinação de pH, CTC, V % e teores de matéria orgânica, P, K+, Ca2+, Mg2+, H + Al e argila. Os dados foram submetidos às análises: estatística descritiva, geoestatística e interpolação por krigagem. Os alcances de dependência espacial para os atributos químicos do solo e teores de argila na camada de 0,60-0,80 m de profundidade foram menores, quando comparados àqueles referentes à camada de 0,00-0,20 m. Estes resultados demonstraram maior descontinuidade na distribuição espacial dos atributos do solo na camada de 0,60-0,80 m de profundidade dos Latossolos, indicando que essa classe de solos não apresentou homogeneidade de seus atributos como conceituadamente a ela foi atribuída. O manejo no solo alterou a dependência espacial dos atributos do solo na camada superficial de forma a diminuir a variabilidade espacial dos atributos químicos do solo em relação à camada mais profunda. A investigação da variabilidade espacial de atributos químicos e do teor de argila da camada superficial e subsuperficial dos solos proporcionou condições para a definição de zonas homogêneas de manejo, o que permite a adoção do sistema de agricultura de precisão.

Agricultura de precisão: mapeamento da produtividade em pomares cítricos usando geoestatística

A variabilidade espacial de produtividade e tamanho de frutos foi avaliada em pomares de laranja irrigados e não irrigados, localizados no município de Luiz Antônio - SP, utilizando-se de geoestatística. Através dos mapas de krigagem, podem-se determinar as áreas de alta e baixa produtividade dos talhões. Verificou-se maior variabilidade para produtividade e tamanho de frutos nas quadras irrigadas e não irrigadas. Portanto, a geoestatística mostrou-se uma ferramenta extremamente útil para auxiliar em Programas de Agricultura de Precisão.

Identidade rural e agricultura familiar :O Pronaf B sob a ótica dos beneficiados

This work has for objective to analyze the perception of benefited of Pronaf B Programa Nacional de Fortalecimento da Agricultura Familiar, in relation to the results that are presented concerning this program. For this, it is presented hypothesis of that the familiar agriculturists, fit in the norms of credit of Pronaf B, have a peculiar perception on the end item of this program, produced from inherent characteristics to the agricultural reality where they live. Ahead of this, I broke myself of estimated of that the searched familiar agriculturists are more socially vulnerable to the inaqualities the agricultural areas. For this research, they had been used, mainly, theoretical reflections of studious of the campesinato, familiar agriculture and of researchers of the impacts of Pronaf B in the agricultural way. The empirical data of the research had been gotten, through the application of questionnaires with the benefited ones and interviews with the mediators of this program in the two searched cities, Apodi and Antônio Martins, in the Rio Grande do Norte, who proportionally withholds the biggest contract number of Pronaf B in the state. The conclusion of the research ratifies the initial hypothesis of that the perception on the results of Pronaf B for benefited its is peculiar, and points stops beyond the economic results, such as: the rise of auto-esteem; the rescue of the citizenship feeling and as impact in autoconsumo of the families of the agriculturists benefited for Pronaf B

Os empoderados da agricultura familiar: capital social nos territórios do seridó e do sertão do Apodi/RN

The study of social practices aims to overcome the theoretical dichotomies that insist on separating the individual from the social structures and vice versa. In this sense, the debate between objectivism and subjectivism in the construction of social reality still has occupied much time and reflection of various scholars of the humanities. Pierre Bourdieu has extensive work that seeks to advance in relation to the theoretical framework of traditional sociological explanations. Bourdieu`s approach regarding social practices is considered by some researchers as a synthesis of classical theories and by others as an attempt of complexify contemporary studies on the significance of social life. This thesis sharesthis effort to understand the social practices of agents, aiming to analyze the strategies of social and political leaders of family farming in the territories of Seridó and Apodi in Rio Grande do Norte, and it has as reference the theoretical and methodological concepts of habitus, field and capital, in Bourdieu. Therefore, we studied the trajectories of social leaders, here called agents as family farming in the two locations in Rio Grande do Norte. As techniques and procedures of the study, we resortedto semi-structured interviews, observations, participation in events and other researches. In conclusion, this thesis gives an account of the construction of two different relational fields for the activities of agents of family farming in the territories of Seridó and Apodi. Although the relational fields in the territories have been structured under the same prevailing institutions, which are: church, union and political party, the social practice of agents shows itself from social position and political variety. Even with the similarities and differences identified and analyzed in different fields of construction, the social relations of the agents in the territories result in the construction of gated communities, the social capital that is the substrate which the agents called empowered .

Agricultura familiar, multifuncionalidade da agricultura e ruralidade: interfaces de uma realidade complexa

The last decades witnessed the revitalization of the debate around family farming with the addition of discussions regarding the multiple functions of agriculture, given the fact that rural areas are longer devoted exclusively to agricultural activities. In the Brazilian context, we believed that this debate must be permeated by analyses of how differentiated processes of land distribution and economic development, and the resulting types of agriculture, generate specific ruralities with characteristics such as, in the case of family farming, the maintenance of social and work practices marked by the relations among relatives and neighbours. It is in this light that this research analyses family agriculture in a rural area of Ouro Fino-MG, its historical heritage, and its participation in the creation of a physical and human landscape that greatly contributes to the attractiveness of the region.

Instituições, agricultura familiar e crédito rural: avaliação de resultados do Pronaf B nos territórios rurais do Rio Grande do Norte

Broadly anchored on Institutionalist literature this dissertation seeks to answer: Why rural credit granted to farming families in Rio Grande do Norte, Pronaf group B, has shown positive results in some territories while in others the same results are insatisfactory? Considering formal rules are the same, then why such results are so distinguished? This research supports the fact that these results are a direct consequence of the quality of institutions defined as longstanding social rules established and built in social interactions. For institutions one understands; organizational structures, formal and non-formal rules, social trust, thinking behaviors and its evolution as well as routines. Using Pronaf Rural Credit as a background this study measures and compares results obtained in the rural areas of Seridó, Sertão do Apodi, Mato Grande, Assú-Mossoró, Trairi, Potengi and Alto Oeste. The dimensions of measurement considered were: economics, social and guarantee of transparency. The study considers a sample of 402 Group B farming families. It also elaborates a socio-economic profile of these families in the considered areas and underlines the main causes for defaulted loans, difficulties to improve family income and results of access to Pronaf B credit line, as well as it proposes solutions to surpass obstacles to improve the efficiency of this credit line

Políticas públicas para agricultura familiar: uma avaliação sobre a correspondência do paa e do PRONAF nos territórios da cidadania do Rio Grande do Norte - 2008 a 2010.

Family farming has been considered as the new axis of rural development in the country, the focus of several public policies, especially the National Program for Strengthening Family Agriculture - PRONAF and Food Purchase Program - PAA. PRONAF was created with the aim of providing credit to farmers, while the PAA to support family farmers through the purchase of its production. In this context, the objective of this study is to analyze the correspondence of these two public policies for family farming, in the Territories of Citizenship of the state of Rio Grande do Norte, between the years 2008 to 2010. In the methodology, the analysis was performed by comparing the distributions of the two programs in the territories of citizenship status. There were also statistical tests of differences in proportions, and Spearman correlations, and estimated a logit regression model, in order to measure the probability of a farmer participating in the PAA is associated with one of the modes of PRONAF. The data used were obtained from the National and Supply - CONAB at the Institute of Technical Assistance and Rural Extension - EMATER, and the Ministry of Agrarian Development - MDA. Among the key findings was noted that policies were associated with a direct, but low in the districts of the Territories of Citizenship. And that, in the years 2008 and 2009, only in the territories of Mato Grande, Alto Oeste and Seridó, the actions of PAA and PRONAF had direct and significant correlations. It was found that in most of the territories, policies are performed randomly, ie that both have no correlation to each other. The estimates of the logit model showed that the chance of a family farmer, the PAA participant, receive credits PRONAF A, is higher in the territory of Mato Grande, and would have a chance to fall in PRONAF B in all areas surveyed. Moreover, farmers in the territories of the Assu-Mossoró, Sertão of Apodi, Seridó and Alto Oeste, participating in the PAA would be more likely to receive credits PRONAF C, reflecting thus the family farm more consolidated these territories
