Description :
This paper re-examines estimates of Cerrado (tropical savanna) vegetation change dynamics using high-resolution satellite remote sensing data from eastern Mato Grosso State. This region has undergone a high degree of typical agricultural development since the early 1970s. Results indicate significant loss of original vegetation as well as high levels of regeneration, suggesting Cerrado vegetation may be more resilient to human impacts than catastrophic estimations suggest. The paper concludes with a critical review of Cerado land-cover change studies and the implications of evidence for vegetation regeneration, land-cover dynamism and land-use intensification, paying particular attention to spatial scale and research methods.
