Eficiência E Energética De Sistemas De Produção De Mamona No Estado De Minas Gerais

Abstract

The objective of this study is to determine the economical and energetic efficiency of the castor bean culture in "Zona da Mata" and South of Minas Gerais. Through the method of simulation "Monte Carlo", we verified the probabilities of occurrence of the economical, cultural and energetic efficiency indexes. In relation to the production systems of castor bean in Minas Gerais in the season 2005/2006, we established that the variables price and productivity were the most noticeable for the producers from "Zona da Mata", while in the South of Minas it was productivity. We verified that the probability of the economical efficiency index to be lower than one was 43,26% for the producers from "Zona da Mata" and 39,57% for the ones from the South of Minas. The medium price received covered the medium costs of production. However, we observed that the medium costs in these regions of Minas Gerais, were over the minimum price. Regarding the energetic analysis, the results showed that the systems in the regions studied in Minas Gerasi, presented average of cultural efficiency indexes of 8,26 and 18,89. We concluded that despite the result being favorable from the energetic point of view, from the economical sustainability point of view there is the need of a more effective support policy for the castor bean, taking into consideration that the expectations of the producers with PNPB were not confirmed.

Análise das eficiências energética e econômica de dois diferentes sistemas de produção de leite bovino em explorações familiares / Analysis of energy and economic efficiencies of two different milk productions in cattle farm family

“…Entretanto, se o resultado for inferior à unidade, tem-se uma indicação que os rendimentos da atividade não cobrem todos os custos de produção. Em se tratando de Ec igual à unidade, mostra que as receitas obtidas cobrem apenas os custos operacionais total de produção, portanto os produtores não estarão obtendo lucro (SILVA, 2008).…”
