Abstract
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 agricultural exploration was
characterized by the intensive use of the soil (agricultural exploration)
and by mechanical and biochemistry technologies; by the intensity of
cattle exploration; and other dimensions of the agriculture. The microrregions
with larger degradation levels concentrated on the northwest of
Minas Gerais, part of south of Goiás, and part of the southeast of Mato
Grosso. The smallest mean values of the degradation index were due to
Tocantins, Piauí and Maranhão. The largest index was from the microrregion
of Primavera do Leste (MT) and the smallest, Jalapão (TO).
