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.

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

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 study turns possible conclude that the women s participations in productive groups in solidary economical change significantly their life and their family life. The group s organisations process, the training was received, the collective production, the marketing and the mobilized participation to move it all was fundamental for women share with their families partners some homemade and take care with the children. 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.
