             abstract = "Woody encroachment is occurring in all tropical savannas of the 
                         world. However, in the Brazilian savanna (the Cerrado), the extent 
                         of this phenomenon is still poorly documented. Here woody 
                         encroachment was quantified throughout the Cerrado biome and 
                         transitional ecotones using a trend analysis of the annual maximum 
                         of enhanced vegetation index obtained from the Moderate Resolution 
                         Imaging Spectroradiometer. The associations with potential local 
                         drivers, such as fire and land use regime, were assessed using 
                         satellite data of land cover and fire regime. We found that 19% of 
                         the remaining native vegetation showed significant evidence of 
                         woody encroachment in the last 15 years and 7% exhibited 
                         degradation processes. The local factors that favored woody 
                         expansion in 19% of the biome were a decrease of fire (34%) and 
                         land use abandonment (26%). Our study highlights that local 
                         human-associated drivers are playing a major role in woody 
                         encroachment and savanna degradation.",
