| Being constituted as the largest risk factor and effective degradation to the Savannah, the man’s intervention in the nature and, especially, the agricultural exploration require analysis and better monitoring. This work aims to analyze the relationship between the agricultural exploration and the environmental degradation in the area of the Savannahs, in 1995-1996. In particular, it is intended, to use multivariate statistical analysis, to verify the factors associated with the intensity of farming predominant in the determination of the degradation pattern, and to obtain indexes of exploration intensity to make possible to categorize and to group the microrregions in terms of degradation potential. The results showed that the intensity of the... |

| The recent transformation in milk production was characterized by the reduction of the prices received by the producer and by the increase of the production and productivity. Facing this reality, this work has the objective to identify whether the option for informal commercialization of the milk was one of the alternatives for the small producers receiving better prices. It was used a logit model to measure the impact of production volume and price received over the probability of producers to opt to sell in informal markets. The results were compatible to what was expected, once the price received per milk litre affects positivelly and the volume production has a negative effect the probability of producers to sell his production at informal markets.... |

| The advancement of investor-owned firms (IOF), mainly multinational ones, and the reduced participation of cooperatives in dairy production and processing in Brazil along the past few decades has been calling the attention of researchers. With the participation of 59 productive units, distributed over 9 states of the Brazilian territory, the objective of this work was to analyze the efficiency of the cooperatives in the dairy industry using the Data Envelopment Analysis (DEA). The results show that, in general, the cooperatives presented better performance in terms of scale rather than in terms of productive efficiency. This stimulates sectorial politicies that promote improvements in the use of the resources to obtain greater efficiency in milk processing. |

| The São José Environmental Protection Area (EPA) in the State of Minas Gerais has a rich natural and historical patrimony. However, in spite of its value and of being a protection area since 1981, it has now suffering several degradations. In that sense, the major objective of this work is to value São José EPA with the purpose of supplying subsidies for the elaboration and attainment of public and private projects of preservation or sustainable exploration of the referred asset, as well as for public policy directed to its administration. As valuation method, it was used the contingent valuation through the approach of Hanemann (1984) and the bootstrapping method to obtain a monthly willingness-to-pay (WTP) per family of the municipal districts that... |

| Dentro do agronegócio brasileiro, o café arábica está entre os produtos com o mais elevado nível de risco e, ainda assim, é um produto importante para a economia brasileira. Os mercados futuros são reconhecidos como meio de gerenciamento desses riscos, mas observou-se o baixo uso desse mecanismo no caso brasileiro. Por outro lado, a literatura tem avançado quanto aos métodos para realização de estratégias de hedge. Em vista disso, esse artigo teve a finalidade de analisar a efetividade, em redução de riscos, de diferentes estratégias de hedge para o café arábica no Brasil. Foram Testadas quatro estratégias: não atuação em mercados futuros; cobertura completa; estratégia estática que incorpora o conteúdo informacional em médias condicionais, obtida pelo... |

| A Gruta do Maquiné, importante ativo ambiental do Município de Cordisburgo-MG, foi formada ao longo de milhares de anos pela natureza. Suas especificidades a tornam fonte de conhecimento e de geração de renda, sendo, portanto, essencial a sua proteção. A determinação do perfil do visitante da Gruta do Maquiné e a estimativa da demanda de visitantes são informações que podem contribuir para a tomada de decisão dos gestores desse ativo. Dessa forma, o objetivo geral deste trabalho consistiu em determinar o valor econômico do ativo ambiental Gruta do Maquiné - MG. Especificamente pretendeu-se: traçar o perfil do turista da Gruta do Maquiné, analisar a resposta dos consumidores às variações na taxa de admissão da Gruta do Maquiné e o excedente do consumidor... |

| O SEGMENTO DE CELULOSE E PAPEL CONTRIBUI DE FORMA SIGNIFICATIVA PARA A ECONOMIA BRASILEIRA. O CONHECIMENTO DA ESTRUTURA DO MERCADO DE CELULOSE É FUNDAMENTAL PARA FINS DE PLANEJAMENTO DA PRODUÇÃO, COMERCIALIZAÇÃO E PREVISÃO PARA O SETOR. O PRESENTE TRABALHO TEM COMO OBJETIVO PRINCIPAL ESPECIFICAR E ESTIMAR A OFERTA E DEMANDA BRASILEIRA DE CELULOSE, BEM COMO A OFERTA E A DEMANDA DE EXPORTAÇÃO, NO PERÍODO DE 1969 A 2005. OS RESULTADOS OBTIDOS, USANDO O MÉTODO MÍNIMOS QUADRADOS DE DOIS ESTÁGIOS (MQ2E), MOSTRAM QUE A OFERTA E A DEMANDA INTERNA DE CELULOSE, BEM COMO A OFERTA E A DEMANDA DE EXPORTAÇÃO SÃO PREÇO-INELÁSTICA. A DEMANDA INTERNA É INELÁSTICA COM RELAÇÃO À RENDA. JÁ A DEMANDA DE EXPORTAÇÃO É ELÁSTICA COM RELAÇÃO À RENDA. A OFERTA INTERNA É MAIS... |

| Foot and mouth disease (FMD) has been a problem for the Brazilian livestock since the XIX century. Once it affects the livestock productivity and has always been a problem for the country exports due to the imposition of sanitary barriers. In 1992, when no state was free from FMD, the National Program for Eradication of FMD (PNEFA) was implemented. Since then good results has been obtained with control and eradication of the disease in some states. However, in other states the problem still persists. It is important to determine why some states have faced difficulties in reaching the status of free from FMD while others not. This work aimed to identify the factors which discriminate the populations of states free from FMD from those not free. The results... |

| In the Brazilian agriculture, there is a great diversity and heterogeneity of production systems that are subject to wide number of factors of risks. Although these risks cannot be completely eliminated, they can be minimized by adopting some strategies, as the diversification with agricultural and cattle activities. Based on the research historical results of the Paraná’s agriculture e with the measurement of the value-at-risk, this work aimed to analyze the volatility of the economic returns of integrated crop-beef cattle systems compared to systems characterized by grain cultivation or beef cattle specialization. As results, we observed that, in the short-term, the integrated crop-livestock system is the alternative that trends to generate better... |

| The objective of this study is to determine the optimum economically location of new slaughter and processing plants of poultry and pork in Brazil, considering the minimization of transportation cost and acquisition of corn and soy bran, and the transportation cost of meat. The theory of localization was used, as theoretical approach, reletead to the weberiana theory of the industrial localization, used, with larger intensity. Network capacited model is used as analytic tool. The main result was the indication of Cândido Mota, SP, for the set the processing plant, due, mainly, a short distance among that municipal district and the corn production cluster and its proximity with important meat consuming areas, and with the main ports. The results indicated:... |

| Analisou-se a elasticidade de transmissão de preços e a formação espacial entre as principais regiões produtoras de leite do Brasil, no período de 1997 a 2005, pela análise de co-integração, e pelo Modelo Vetorial de Correção de Erro (VEC). Os resultados evidenciaram que a variação de 1% nos preços recebidos pelos produtores de leite de Minas Gerais leva a uma variação de 0,38%, 0,72%, 0,93% e 0,26% nos preços em São Paulo, Rio Grande do Sul, Paraná e Goiás, respectivamente. Pela estimação do VEC os coeficientes do Paraná e São Paulo, em módulo, foram comparativamente maiores aos demais. São Paulo foi menos interdependente, indicando comportamento mais isolado no padrão de liderança preço. Verificou-se que, com o passar dos meses os preços de Minas... |
