Análise competitiva na cadeia produtiva da uva orgânica em uma vinícola da serra gaúcha através da MAP (Matriz de Análise de Política)

Nicaretta, Leandro 26 June 2014 (has links)
Este estudo teve o objetivo de através da MAP analisar a competitividade da uva orgânica em relação a sua cadeia produtiva e as maneiras de calcular os custos e ser utilizado como diferencial de negócio para os produtores. Dentro da evolução da cadeia da uva orgânica existem duas alternativas de produto, sendo que uma delas é a produção convencional, que demonstra perda de espaço para a produção orgânica. Produção esta que tem se mostrado mais rentável para os produtores. Dessa forma, a análise de competitividade da cadeia da uva orgânica teve como finalidade apresentar a MAP como método quantitativo destinado a medir o impacto das políticas, a lucratividade e a eficiência, de uma vinícola da serra gaúcha apresentando a existência de viabilidade econômica na região, grande produtora da variedade orgânica do produto. Dentre os principais resultados está preço pago pelo pela iniciativa privada segundo a avaliação realizada nesta pesquisa através da MAP apresentou os seguintes valores R$1,95 ao quilo e no cenário público social obtivemos R$ 2,30 apresentando uma diferença de 0,35 centavos por quilo, remunerando de maneira inferior o produto no mercado. Mesmo a cadeia como um todo apresentar um resultado positivo um Lucro Privado de R$ R$ 30.704,75 e coeficiente de lucratividade de 1,63 que representa ser um índice bastante aceitável para a cadeia em questão. / Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2015-02-06T16:02:55Z No. of bitstreams: 1 Dissertacao Leandro Nicaretta.pdf: 1469517 bytes, checksum: 21e10f550a4dd16ec3c247f04675916e (MD5) / Made available in DSpace on 2015-02-06T16:02:55Z (GMT).

Within the evolution of the organic grape chain there are two product alternatives, one of which is the conventional production, demonstrating loss of space for organic production. This production has been more profitable for producers. Thus, the analysis of competitiveness of organic grape chain aimed to present the MAP as a quantitative method to measure the impact of policies, profitability and efficiency, a winery in Serra gaúcha showing the existence of economic viability in the region, major producer of organic product variety. Among the main results is the price paid by the private sector according to the evaluation conducted in this study through MAP showed the following values R $ 1.95 to the pound and public social scene obtained R $ 2.30 showing a difference of 0.35 cents per pound, paying way below the product to market. Even the chain as a whole present a positive result one Private Profit of R $ R $ 30,704.75 and profitability coefficient of 1.63 which is quite acceptable to be an index to the string in question.

Vliv produkčních procesů při pěstování brambor na emise CO2 / Influence of production proces during potatoes growing on CO2 emissions

JAREŠOVÁ, Martina January 2011 (has links)
The thesis deals with the partial evaluation of life cycle of the potatoes and its environmental impact during the all phases of the cycle. The cycle consists of the evaluation of emission load in the field production, processing and transportation to processing and end-users. The evaluation compared the emission load variations, such as organic and conventional potatoes, seasonal and stored potatoes, raw potatoes and processed potato products. For calculating the emission load was used software tool SimaPro. The aim of work was to find which forms of cultivation; processing and transport have the lowest environmental impact and propose variants with low environmental impact to school canteens.

The research aims to know the origin of the seeds of vegetables grown in the world, in Brazil and next to the Association for the Development of Organic Agriculture of Goiás (ADAO). The behavior of the countries of Europe, Argentina, Chile, Japan and the United States were studied through a bibliographic review, which focused on the organic legislation and its requirements related to the use of the seed. In Brazil, organic production and research initiatives were studied through bibliographic review and interviews. Also through interviews conducted from April to December 2017, the main difficulties faced by ADAO farmers in producing and using organic vegetable seeds were studied. International legislation, because it originates in the same documents, resembles the requirements for seeds. Europe stands out because it has not allowed the use of conventional seeds since 2013. Brazilian research institutions, companies and associations that work with organic seeds of vegetables sell few seeds, but contribute to the development of the sector, stimulating the farmer to develop their production. In Goias, despite the diversity in cultivation, with 52 species of different vegetables, the dependence of conventional seeds is still high and one way to minimize it would be the production of own seeds. The change in this scenario is not sudden, nor can it depend only on one sector, it is a joint effort. Successful experiences must be exchanged, replicated, and each region adapting to the best solution. / A produção de hortaliças orgânicas sofre com a falta de disponibilidade de sementes adequadas para seu cultivo. A pesquisa tem como objetivo conhecer a origem das sementes de hortaliças cultivadas no mundo, no Brasil e junto à Associação para o Desenvolvimento da Agricultura Orgânica de Goiás (ADAO). O comportamento dos países da Europa, Argentina, Chile, Japão e Estados Unidos foram estudados através de revisão bibliográfica, que teve como foco a legislação orgânica e suas exigências relacionadas ao uso da semente. No Brasil, foram estudadas as iniciativas de produção e pesquisa com sementes orgânicas, através de revisão bibliográfica e entrevistas. Também por meio de entrevistas realizadas no período de abril a dezembro de 2017, foram estudadas as principais dificuldades dos agricultores da ADAO, em produzir e utilizar sementes orgânicas de hortaliças. A legislação internacional, por ter origem nos mesmos documentos, assemelha-se nas exigências às sementes. A Europa se destaca por não permitir o uso de sementes convencionais, desde 2013. As instituições de pesquisa brasileira, empresas e associações que desenvolvem trabalhos com sementes orgânicas de hortaliças comercializam pouca quantidade de sementes, mas contribuem para o desenvolvimento do setor, estimulando o agricultor a desenvolver sua produção. Em Goiás, apesar da diversidade no cultivo, com 52 espécies de hortaliças diferentes, a dependência das sementes convencionais ainda é alta e uma forma de minimizá-la seria a produção de sementes próprias. A mudança neste cenário não é repentina, nem pode depender apenas de um setor, é um trabalho conjunto. As experiências de sucesso devem ser trocadas, replicadas e cada região se adaptar a melhor solução.

The experiment was conducted at Universidade Federal de Goiás - Campi Jataí, and implemented on November 30th, 2015. The experimental design has happened with randomized blocks (RBD) with eight treatments (2012-38, 2012-71; 2013-293, 2013-415; 2013-413 OL; 2013-415 OL), and with the commercial varieties Runner IAC 886 and IAC 505 in four replications. The characteristics evaluated are divided into two categories: (a) Productivity, measured by weighing the parcel; and (b) Weight of 100 pods; weight of seeds in 100 pods and the weight of 100 seed. After the sowing time, period of 88, 119 and 140 days, the weighing of fresh and dry matter of fruit, stem and roots have been made. During the cycle of the plants, there were photographic records for the growth and coverage factor analysis. The manual harvesting process of the crop, on April 28th, 2016 (corresponding to 140 days after sowing), happened when 60% to 70% of the pods presented brown color pigments inside. Through linear regression, it was possible to estimate the fruiting period by subtracting the days of maturity (harvest) from the fruiting ones. The evaluated strains differ statistically with a emphasis on the lineage 13-425OL productivity. Based on the parameters studied, the strains have the potential to be cultivated through the organic system. Fungal diseases caused significant losses on the coverage factor. / Nessa pesquisa objetivou-se avaliar o desempenho de seis linhagens de amendoim e duas cultivares, com base em indicadores produtivos, em sistema de transição orgânico na região de Jataí- GO. O experimento foi conduzido na Universidade Federal de Goiás - Regional Jataí, e implantado no dia 30 de novembro de 2015. O Delineamento experimental foi em Blocos Casualizados (DBC) com oito tratamentos (2012-38; 2012-71; 2013-293; 2013-415; 2013-413 OL; 2013- 415 OL), e com as variedades comerciais Runner IAC 886 e IAC 505 em quatro repetições. As características avaliadas se dividem em duas categorias: (a) Produtividade: avaliada através de pesagens do peso de vagens das parcelas, e (b) peso de 100 vagens, peso das sementes em 100 vagens e o peso de 100 sementes; Aos 88, 119 e 140 dias após a semeadura, foram feitas pesagens de matéria fresca e seca de frutos, assim como caules e raízes. Durante todo o ciclo das plantas, houve registros fotográficos para análise de crescimento e fator de cobertura. A colheita realizada, no dia 28 de abril de 2016 (correspondente a 150 dias após a semeadura), aconteceu quando 60% a 70% das vagens apresentavam pigmentos de cor marrom na parte interna. Por meio dos parâmetros de regressão, foi possível estimar o período de frutificação ao subtrair os dias de maturação (colheita) dos dias de frutificação. As linhagens avaliadas diferiram estatisticamente, com destaque maior de produtividade na linhagem 13-425OL. Com base nos parâmetros estudados, as linhagens apresentam potencial para serem cultivadas sob o sistema orgânico. As doenças fúngicas causaram perdas significativas no fator de cobertura.

Percebe-se que há um lugar reservado aos produtos orgânicos em grandes redes de supermercados e que, apesar do preço superior aos similares produzidos sem a tecnologia orgânica, a demanda por este produto tem aumentado. O trabalho buscou explicitar as insuficiências e limitações das práticas de mercado dos produtos orgânicos em supermercados e o risco da adoção dos mesmos pelos pequenos agricultores orgânicos, como base para buscar melhorar este canal e/ou pensar em outros canais de comercialização. Para cumprir com esses objetivos foram analisadas diferentes estratégias de comercialização adotadas pelos supermercados. Foram selecionados para estudo 10 supermercados na região do Pólo Bandeirante do estado de São Paulo, onde os produtos orgânicos foram comparados com os não orgânicos: preços praticados e estratégias de mercado. Foi verificado que há uma diferença significativa de preço de produtos orgânicos quando comparado com os não orgânicos tornando o mesmo acessível a apenas uma parcela da população e tendo como conseqüência um desserviço ao movimento de agricultura orgânica / Abstract: Significantly increasing number of consumers of organic products , the concern with the effects of food intake on a day- to-day with regard to health and its action on the environment. It is noticed that there is a place reserved for organic products in large supermarket chains and that , despite the higher price to similar produced without organic technology , the demand for this product has increased. The study sought to explain the shortcomings and limitations of market practices organic produce in supermarkets and the risk of adopting the same by small organic farmers , as a basis for seeking to improve this channel and / or think of other marketing channels . To fulfill these objectives were analyzed different marketing strategies adopted by supermarkets . Were selected for study 10 supermarkets in the Bandeirante pole of São Paulo , where organic products were compared with non- organic region : prices and market strategies . It was found that there is a significant price difference of organic products compared with non- organic making it accessible to only a portion of the population and as a consequence having a disservice to the organic farming movement / Mestrado / Planejamento e Desenvolvimento Rural Sustentável / Mestre em Engenharia Agrícola

The "New Rural Reconstruction" : movement and sustainable agricultural development in China / La "nouvelle reconstruction rurale" : le mouvement et le développement agricole durable en Chine

Guo, Huanxiu 23 October 2013 (has links)
Cette thèse étudie le mouvement de la Nouvelle Reconstruction Rurale (NRR) sous l'angle du développement durable, en prenant l'exemple concret du village de Sancha, une communauté rurale de la province du Guangxi en Chine. Initié en 2003, la NRR est un réseau national de projets de développement qui réunit des intellectuels, des étudiants et des organisations dont l'objectif estd'expérimenter différents modèles de développement agricole et rural en Chine. Comme alternative à l'industrialisation agricole, la NRR favorise la coopération entre les petits agriculteurs, le savoir-faire local et l'agro-écologie pour le développement durable de l'agriculture. Afin de comprendre ses caractéristiques institutionnelles, son fonctionnement et son impact, nous avons mené une enquête dans le village de Sancha pour collecter des données sur les comportements socio-économiques de petits exploitants agricoles, et proposé trois études de cas sur la NRR. Nos analyses empiriques suggèrent que la NRR a promu le développement de l'agriculture biologique dans le village. Les activités sociales sont efficaces pour la construction du réseau social via lequell'agriculture biologique a été diffusée rapidement. Néanmoins, sans la formation technique suffisante et continue, les paysans récemment convertis à l'agriculture biologique tendent à sur-utiliser l'azote et perdent leur avantage environnemental dans la riziculture. Pour améliorer la performance des petits paysans, l'apprentissage participatif social paraît utile mais limité car les petits agriculteurs sont plutôt tirés par la performance économique que par la protection environnementale. De ces résultats, nous recommandons un partenariat Etat-société civile qui combine les services d'extension agricole du gouvernement et la reconstruction rurale ascendante pour l'objectif commun d'une agriculture durable en Chine. / This doctoral thesis studies the New Rural Reconstruction (NRR) movement from a sustainable development perspective, through a concrete case of Sancha village, a rural community in China's Guangxi province. Initiated in 2003, the NRR is a grassroots network of development projects which unites intellectuals, students and organizations to experiment with different models of agricultural and rural development in China. As an alternative to agricultural industrialization, the NRR favors the cooperation of smallholder farmers, local knowledge and agro-ecology for sustainable agricultural development. In order to understand the NRR's institutional characteristics, functioning and impact, we conducted a survey in Sancha village to collect data on smallholder farmers' socio-economic behavior and performed three in-depth NRR case studies. Our empirical analysis suggests that the NRR has promoted the development of organic farming in the village. Social activities are cost-effective for social network building where organic farming is diffused rapidly. Nevertheless, without sufficient, ongoing technical training, farmers newly converted to organic farming tend to overuse nitrogen and lose their environmental advantage in rice production. To improve the performance of smallholder farmers, participatory social learning appears useful but limited because smallholder farmers are interested in economic performance rather than environmental protection. On basis of these results, we recommend a state-civil society partnership which combines the government's agricultural extension services and bottom-up rural reconstruction for the commonobjective of sustainable agriculture in China.

Institutional dynamics in a small-scale organic farming organisation : the case of the Ezemvelo Farmers' Organisation

Msomi, Thulisile Felicity January 2017 (has links)
Magister Philosophiae (Land and Agrarian Studies) - MPhil(LAS) / This study explores institutional dynamics within an organic farming organisation, the Ezemvelo Farmers' Organisation (EFO), based in uMbumbulu in KwaZulu-Natal (KZN). The main objective of the study was to identify the institutional and governance factors that impact on the sustainability of the organic production programme of the EFO. A variety of research methods were employed, including a small sample survey of 50 households, in-depth interviews with key respondents, and a critical assessment of the existing literature on the EFO. The study established that many rural households in uMbumbulu maintain their livelihoods through a diverse array of activities that include social grants. Agriculture remains an important livelihood strategy for many households. It presents opportunities for income generation, access to food, job creation and increased asset accumulation. Communal land tenure systems do not constrain agricultural development, and kinship ties and social relations determine affordable and flexible land access for farming and residential use. The EFO initiave regenerated agricultural production in uMbumbulu. Many households have rights to cropping fields and these fields were revitalised and put under productive use as the organic farming initiative gained momentum. The EFO marketed its produce to Farmwise, a packhouse that distributes produce to various retailers. The agro-food industry is dominated by large business interests and maintained exploitative relations with the EFO. Organic production and marketing to such businesses imposed high transaction costs on members of the EFO as onerous quality standards were enforced throughout the value chain. Rural development interventions that are driven by external stakeholders such as academic institutions, government departments and other agencies tend not to provide sustainable solutions to help support the development of smallholder farmers. In the case of the EFO, such support saw abuses of power, elite capture, free-rider problems, conflict and weak management systems. The thesis argues that the agrarian transformation imperative means that policy frameworks must be re-examined, and adapted to the needs and local practices of smallholder farmers such as members of the EFO. Proper extension support that provides accurate market information, effective coordination of production and transport services, and relevant infrastructure, is also required. / National Research Foundation (NRF)
