A Intensidade da Exploração Agropecuária como Indicador da Degradação Ambiental na Região dos Cerrados, Brasil AgEcon
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...

Eficiência técnica na atividade leiteira de Minas Gerais: um estudo a partir de três sistemas de produção AgEcon
Ferreira Junior, Silvio; Cunha, Nina Rosa da Silveira.
Because of the importance of the dairy activity in Brazil and the recognized call for increasing domestic production, the objective of this work was to verify technical efficiency levels in three alternative production systems, using the stochastic production frontier model. Factorial analysis was used to evidence the heterogeneity of resources applied to the activity, which allowed the 11 original quantitative variables to be synthesized in only three characteristic management variables - "machine use", “facility use" and "quality of the herd". Three additional variables, characteristic of the professionalization of the activity, were considered: “specialization", "scale" and "average cost". Both categories of variables allowed the levels of technical...
