Spatiotemporal Dynamic Analysis of Heat Spots in Two Indigenous Lands of Mato Grosso State: a Geoespatial Approach Over the a Dynamic of Fire Use by Xavantes and Bororos

ABSTRACT The article aimed to use geotechnology to study the occurrence of heat spots detected sensors on board of NOAA-12 and NOAA-15 satellites, between the years 2000 and 2010 in a region located on east of Mato Grosso state. It was observed that in the Merure, belonging to Bororo people and São Marcos, belonging to Xavante people indigenous lands the heat spots were presented in different patterns that can be attributed to the distinct ways of fire management by each ethnic group. The practice of hunting with the use of fire influenced the higher concentration and considerable densities of hot spots distributed throughout inside the Xavante`s territory compared to the Bororo´s and in the surrounding buffer areas of São Marcos. In the Bororo territory was observed that the hot spots were presented in higher densities close to the highways that crosses its territory.
