                         to atmosphere, alter the radiation balance and reduce 
                         photosynthetic rates of vegetation. These emissions can interfere 
                         in the rainfall regime and affect the health of population. The 
                         aim of this work was to answer the following questions: (i) is 
                         there any temporal trends on fire behavior in the Amazon? (ii) 
                         where do these trends occur and what is the spatial extent of 
                         significant trends? (iii) what is the magnitude of these trends? 
                         For answering these questions, we used active fire detection data, 
                         aggregated at 729 km2 cell grid for analyzing the entire Brazilian 
                         Legal Amazon, during the years 2002-2014. We used two 
                         non-parametric statistical methods to analyze the regional and 
                         local trends, as well as quantify its magnitude (Mann-Kendall and 
                         Sens Slope, respectively). We found evidence of a significant 
                         tendency in regional reduction of fires between the years 
                         2002-2014 (at 10% of significance; p-value = 0.077). Locally 
                         significant trends (p-value < 0.05) were observed in the reduction 
                         of fires, mostly in the Arc of Deforestation region; however, 
                         there was a significant (p-value < 0.05) increase in areas of 
                         deforestation frontiers, especially in Cerrado (Brazilian Savanna) 
                         areas. The areas with negative trends are possibly related to the 
                         reduction in deforestation rates, whereas the areas with positive 
                         trend were associated with an increase of deforestation.",
