Item Interaction between climate, flowering and production of dry coffee (Coffea arabica L.) in Minas Gerais(Editora UFLA, 2021) Soares, Lidiany dos Santos; Rezende, Tiago Teruel; Beijo, Luiz Alberto; Franco Júnior, Kleso SilvaAiming to determine the interaction between climatic factors, flowering and yield of dry arabica coffee in municipalities in the regions of Southern Minas Gerais and Alto Paranaíba, both in the State of Minas Gerais, this study considered data from the harvest years 2008/2009 to 2017/2018, and climatic data analyzed according to the coffee phenological cycle. The determination of significant variables used the Stepwise method and the Akaike Information Criterion (AIC). The association of yield with climatic variables used a generalized linear model with gamma distribution and logarithmic function. Average flowering (20% to 50% of flowers per branch) used a logistic regression model. The productive variability of arabica coffee showed an association with the biennial cycle, the occurrence of medium and main flowering, flowering period and rains in bean formation. The occurrence of average flowering and the frequency of rainfall during bean formation enhanced coffee yield, at the same time as the increment in maximum temperature in vegetative bud formation reduced flowering and yield.Item The continual improvement in the certification of coffee farms: a case study(Editora UFLA, 2018-10) Castro, Claúdio Vieira; Lira, Jean Marcel Sousa; Salgado, Eduardo Gomes; Beijo, Luiz AlbertoThe certification of agricultural products is considered a strategy that promotes sustainability and appreciation of product. In coffee production, the Certifica Minas Café is the only public coffee certification program in Brazil. However, over the years, many coffee farms that have this certification reduce their competence to meet the requirements, stabilizing at minimum levels of compliance, which allows maintaining the certificates, but does not promote continual improvement. Therefore, this study aimed to evaluate the effect of Certifica Minas Café certification on the improvement of sustainability over time on coffee farms. For this, a case study with two properties in the south of the state of Minas Gerais was carried out in which one of them quest to not achieve continuous improvement, while the other does. On the coffee farm of the first case was observed a reduction of number of requested fulfilled by the certification program over time. While coffee farm of the second case there was a reduction in investment and low concern to maintain the requirements established by the certification. Lastly, this paper hypothesizes that improvement of sustainability depends on understanding the benefits of certification in the long term and is related to a behaviour change by the certified farm.Item Certifica Minas Café: um novo paradigma da atuação do estado na proteção ambiental?(Editora UFLA, 2017-10) Castro, Claudio Vieira; Salgado, Eduardo Gomes; Beijo, Luiz AlbertoO programa Certifica Minas Café (CMC) é uma iniciativa do governo do Estado de Minas Gerais para a certificação de propriedades cafeeiras. É o único programa de certificação de lavoura de café promovido pelo Poder Público. Esta pesquisa abordou um dos desafios do programa: lidar com as não conformidades encontradas nas auditorias e que possam representar o descumprimento de obrigações legais, pois os auditores do CMC possuem também atribuições de fiscalização da utilização de agrotóxicos. A pesquisa teve acesso a 570 relatórios de auditorias realizadas pelo programa no ano de 2015, tomando-se uma amostra de 230. Dos relatórios foram extraídos os dados referentes a seis requisitos da certificação, associados aos agrotóxicos. Adicionalmente, foram realizadas entrevistas com o gestor do programa e examinados os procedimentos e formulários da certificação. A maior contribuição desta pesquisa é apresentar e discutir a hipótese de que a certificação pública de propriedades e de produtos agrícolas pode ser considerada como um novo paradigma da atuação do Estado na proteção ambiental. O modo de atuação estatal na certificação não se enquadra nos paradigmas anteriores e proporciona resultados importantes no atendimento aos parâmetros técnicos e legais desejados, permitindo sugerir que sua utilização seja ampliada para outros setores, além da cafeicultura.
