		<abstract>The Brazilian Cerrado vegetation has been increasingly threatened over the last decades and the significant loss of ~50% in its native cover is also related in part to the absence of  a  consistent  fire  policy  in  the  region.  Although  the  Cerrado  is  adapted  to  natural  fires  the significant changes in fire regimes might alter this biome irreparably. With future projections of a drier and warmer climate, it is thus crucial to understand how fire regimes are evolving to allow a better management and allocation of resources. Satellite technology currently provides a tool to effectively study fire regimes through the identification of active fires and burned areas (BA). Here we use the MODIS MCD64A1 Collection 6 product to evaluate BA patterns in Cerrado over the last  18  years  (2001-2018).  Intra  and  inter-annual  variabilities  are  assessed  along  with  spatial analysis, with special focus on the existing Conservation Units; the existence of significant trends and shifts are also investigated. Results show that the dry period from August to October accounts for around 60% of the total BA. Fire extent varies considerably from year to year showing a strong dependence  on  climatic  conditions,  which  are  responsible  for  more  than  2/3  of  the  interannual variability of burned area for the last two decades. Very distinct patterns for its South-western and North-eastern  and  regions  are  seen,  with  negative  and  positive  trends,  respectively.  The  latter region is the new agricultural frontier with extensive and mechanized farms, whereas the former has  mostly  been  cleared  of  native  vegetation  and  is  now  dominated  by  grasslands  and  small-scale  croplands.  Conservations  units  near  by  the  Arc  of  Deforestation  and  the  new  agriculture frontiers of MATOPIBA present the higher amount of burned area.</abstract>
