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.",
