Cunha, Nina Rosa da Silveira; Lima, Joao Eustaquio de; Gomes, Marilia Fernandes Maciel; Braga, Marcelo Jose.
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...

These applications are complementary to the identification of key sectors of the economy. The 1995 input-output matrix was used. Linkages indexes of Rasmussen-Hirschman and the analysis of the influence field pointed out that coffee production presents multiplying indicators above those of the economy, presenting higher backward and forward linkages. The coffee...

Effects of the Public Policies on the Natural Rubber Production in Sao Paulo and Mato Grosso States AgEcon
Rosado, Patricia Lopes; Tosto, Sergio Gomes; Gomes, Marilia Fernandes Maciel; do Carmo, Ciriaca A.F. Santana.
The objective of this study was to evaluate the effects of the government intervention on the expansion of the natural rubber production in Sao Paulo and Mato Grosso states. The method used was the policy analysis matrix, developed by MONKE and PEARSON (1989). The results showed that the production of natural rubber in those states has conditions to face the liberalization changes that have been taking place in the international market. The government's role in that process is relevant in order to promote the development of that activity and to reduce the distortions, since these impede that the market signals guide the producer decisions in an integrated economy into the world market. Some policy measures can be carried out to improve the competitiveness...

Santos, Venussia Eliane dos; Gomes, Marco Tulio M.; Gomes, Marilia Fernandes Maciel.
This paper aimed to assess the changes in the consumption quantity of roasted and ground coffee in response to changes in the consumers' income, in the Southeast Region of Brazil, specifically in the states of Minas Gerais, São Paulo and Rio de Janeiro, and in all areas of the covered by the POF (Brazil). For that, the income elasticity of the consumption of those types of coffees was estimated by using an econometric model that fitted a three-segment polygon to show as the per capita physical consumption of those types of coffee varies as the per capita family monthly income changes. The data were gathered from the Family Budget Survey for the years of 2002/2003, published by the IBGE. The estimated income elasticity for roasted and ground coffee was...

Paula, Eduardo Vitor de; Gomes, Marilia Fernandes Maciel; da Silva Junior, Aziz Galvao.
The coffee roasting segment is passing through deep transformation since the beginning of the 90´s, and the requirement of quality has been essential for the performance of those companies in the market. The quality factor has been playing important role for the competitiveness of the enterprises. Some authors believe that, under the aegis of the market globalization, the quality reaches its highest level of importance in the business decision process and turns out to be the passport for opening the most challenging markets and for upholding the niches in the more competitive markets. However, systems or quality programs generate costs that, usually, are unknown for the firms. In Brazil, the literature on the costs of the quality lacks more comprehensive...

Impactos da influenza aviária no mercado internacional de carnes AgEcon
Valente, Luiza Carneiro Mareti; Gomes, Marilia Fernandes Maciel; Campos, Antonio Carvalho.
Animal infectious disease outbreaks as Avian Influenza, Foot and mouth disease and Bovine Spongiform Encephalopathy can influence trade and bring economic consequences to affected countries. For this reason, this work aims to analyze the effects on meat import demand in the years of 1997 and 2003 to 2005, the Avian Influenza outbreaks period. The analytical framework used was panel data econometrics. The results point to a reduction on chicken meat demand in 1997 and increase to the other meats, indicating a possible substitution. From 2003 on, chicken meat demand showed slight increase, as did pig meat, only bovine meat demand showed a reduction. This fact can be explained by a restriction on bovine and chicken supply caused by the imposition of sanitary...

Andrade, Wendel Sandro de Paula; Gomes, Marilia Fernandes Maciel; Santos, Heleno do Nascimento; Lima, Joao Eustaquio de.
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:...
