             abstract = "The Brazilian Cerrado is considered to be the most species-rich 
                         savannah region in the world, covering ~2 million km2. 
                         Uncontrolled late season fires promote deforestation, produce 
                         greenhouse gases (~25% of Brazil's land-use related CO2 emissions 
                         between 2003 and 2005) and are a major threat to the conservation 
                         of biodiversity in protected areas. Governmental institutions 
                         therefore implemented early dry season (EDS) prescribed burnings 
                         as part of integrated fire management (IFM) in protected areas of 
                         the Cerrado, with the aim to reduce the area and severity of late 
                         dry season (LDS) fires. The planning and implementation of EDS 
                         prescribed burning is supported by satellite-based geo-information 
                         on fuel conditions, derived from Landsat 8 and Sentinel-2 data. 
                         The Mixture Tuned Matched Filtering algorithm was used to analyse 
                         the data, and the relationship between the resulting matched 
                         fractions (dry vegetation, green vegetation and soil) and in situ 
                         surface fuel samples was assessed. The linear regression of in 
                         situ data versus matched filter scores (MF scores) of dry 
                         vegetation showed an r2 of 0.81 (RMSE\ =\ 0.15) and 
                         in situ data versus MF scores of soil showed an r2 of 0.65 
                         (RMSE\ =\ 0.38). To predict quantitative fuel load, 
                         a multiple linear regression analysis was carried out with MF 
                         scores of NPV and soil as predictors (adjusted 
                         r2\ =\ 0.86; p\ <\ 0.001; standard 
                         error\ =\ 0.075). The fuel load maps were 
                         additionally evaluated by fire managers while planning EDS 
                         prescribed burning campaigns. The fuel load mapping approach has 
                         proven to be an effective tool for integrated fire management by 
                         improving the planning and implementation of prescribed burning, 
                         promoting pyrodiversity, prioritising fire suppression and 
                         evaluating fire management efforts to meet overall conservations 
                         goals. National and state level authorities have successfully 
                         institutionalized the approach and it was incorporated into IFM 
                         policies in Brazil.",
