             abstract = "A worldwide increase in the number of vegetation fires occurred in 
                         the last decades and Brazil accounts for the highest records in 
                         South America. The use of fire is still common as a tool for soil 
                         management, deforestation, pasture renewal and manual sugar-cane 
                         harvesting in developing regions. However, inadequate fire use 
                         causes socioeconomic and environmental damages. In this context, 
                         an assessment of the potential fire risk of vulnerable lands can 
                         be used to minimize harmful consequences and promote sustainable 
                         land management and practices. Therefore, the aim of this study 
                         was to evaluate the seasonal predominant fire risk in the 
                         Brazilian biomes (Amazonia, Caatinga, Cerrado, Mata 
                         Atl{\^a}ntica, Pampas e Pantanal) from 2001 to 2017 according to 
                         the fire risk (FR) model from Center for Weather Forecasting and 
                         Climate Studies/National Institute of Space Research (CPTEC/INPE). 
                         The FR model estimates the daily fire risk in a given region based 
                         on the number of consecutive days without precipitation during the 
                         last 120 days, the maximum daily temperature, the minimum daily 
                         relative air humidity and the local vegetation type. The 
                         meteorological data were obtained from the Climate Prediction 
                         Center and from reanalysis of the European Center for Medium-Range 
                         Weather Forecasts Interim Reanalysis. The vegetation type is a 
                         reclassification of Brazil0 s MapBiomas v3.0 dataset in seven 
                         predominant land cover classes defined by the Brazilian Institute 
                         of Geography and Statistics-IBGE. All input datasets were 
                         interpolated to a grid of 25x25km spatial resolution. From the 
                         daily FR data, the monthly predominance of FR in each biome was 
                         calculated, issuing the monthly median values within the 25th and 
                         75th percentiles values for the same month of all years. The 
                         predominant FR values were evaluated in five categories: 
                         1-minimum: FR<0.15, 2-low: 0.15<FR<0.40, 3-medium: 0.40<FR<0.70, 
                         4-high: 0.70<FR<0.95 and 5-critical: FR>0.95). The biomes showed 
                         different seasonal distributions of FR. Caatinga, Cerrado and 
                         Pantanal were the biomes with more months susceptible to fire, 
                         with medium to high FR, and concentrated in the dry season (June 
                         to November, May to October and June to September, respectively). 
                         Amazonia, with \∼5 million km2, and Pampas showed minimum 
                         to low FR, with maximum values in August. Mata Atlantica has a 
                         low-medium FR from April to September. This study showed that an 
                         adequately fire use in the land management and agricultural 
                         practices or prescribed fires to minimize fuel to avoid dangerous 
                         forest fires must be applied in different periods for each biome
