biomass burning is a major source of greenhouse gas emissions in developing countries. in colombia, land use change, forestry and agriculture are responsible for more than 50% of the total greenhouse gas emissions. fire is commonly used as a mechanism for land use change. in colombia the llanos orientales and the amazonia are subject to biomass burning every year during the dry season, especially from january to march. studies of the spatial and temporal distribution of emissions are required for emissions report at a national level. the goal of this state of the art article is to describe a method to estimate emissions with a remote sensing approach and to present some of the variables already measured in colombia.
