Abstract

This work aims to use indicators to assess the pasture expansion process in the Pantanal of Cáceres-Mato Grosso, from 1999 to 2014. A spatiotemporal analysis of the past 15 years was carried out with time interval of 5 years, through images of Landsat 5 and Landsat 8. Three land use classes were mapped: Natural Forest Vegetation, Pasture and Forested Savannah + Grassy-Woody Savannah. The generated classes enable the calculation of indices for the determination of an environmental scenario in the study area. The indicators showed a growing increase in pasture area in the order of 182.34% to Pasture Occupation Index and 23.08% to Pasture Expansion Index until 2014 and showed that the suppression of Natural Forest Vegetation is greater than the suppression of Forested Savannah and Grassy-Woody Savannah. The oscillation of the indices during the study period can be attributed to the occurrences of forest fires, droughts, floods and flow. The indicators showed that despite the pasture expansion, the Pantanal of Cáceres is a region with a complex environmental dynamic, enriched and diversified, suggesting the need for constant monitoring to check human actions that threaten its environmental balance.
