The Amazon is composed of a wide variety of ecosystems and forms of occupation, taking a wide variety of settings, including spatial, social, economic, agronomic, which vary from region to region. From this perception of the Amazon region, this work presents an investigative study scenarios and their correlations, in order to quantify and qualify the strength of relationships and dependencies between the different variables involved, such as meteorological factors (relative humidity, rainfall, speed wind and temperature) and the number of fire outbreaks, in order to enable the analysis of the reasons that influence the environmental degradation of the study area. In order to validate the proposed methodology, we conducted a study in the city of Maraba area of settlement projects, whose focus is to analyze the correlation between climate variables and fire outbreaks in the region, using three study scenarios. Therefore, we use some statistical parameters, the Pearson correlation and Bayesian networks in order to establish the degree of dependency between the different variables of interest. From such studies, it is possible to make a set of inferences about the problem under study and possible alternatives, which more balance scenarios for the benefit of environmental sustainability.
