abstract = "The main objective of our study was to provide consistent
information on land cover changes between the years 1990 and 2010
for the Cerrado and Caatinga Brazilian seasonal biomes. These
areas have been overlooked in terms of land cover change
assessment if compared with efforts in monitoring the Amazon rain
forest. For each of the target years (1990, 2000 and 2010) land
cover information was obtained through an object-based
classification approach for 243 sample units (10 km × 10 km size),
using (E)TM Landsat images systematically located at each full
degree confluence of latitude and longitude. The images were
automatically pre-processed, segmented and labelled according to
the following legend: Tree Cover (TC), Tree Cover Mosaic (TCM),
Other Wooded Land (OWL), Other Land Cover (OLC) and Water (W). Our
results indicate the Cerrado and Caatinga biomes lost (gross loss)
respectively 265,595 km2 and 89,656 km2 of natural vegetation (TC
+ OWL) between 1990 and 2010. In the same period, these areas also
experienced gain of TC and OWL. By 2010, the percentage of natural
vegetation cover remaining in the Cerrado was 47% and in the
Caatinga 63%. The annual (net) rate of natural vegetation cover
loss in the Cerrado slowed down from \−0.79% yr\−1
to \−0.44% yr\−1 from the 1990s to the 2000s, while
in the Caatinga for the same periods the rate increased from
\−0.19% yr\−1 to \−0.44% yr\−1. In
summary, these Brazilian biomes experienced both loss and gains of
Tree Cover and Other Wooded Land; however a continued net loss of
natural vegetation was observed for both biomes between 1990 and
2010. The average annual rate of change in this period was higher
in the Cerrado (\−0.6% yr\−1) than in the Caatinga
(\−0.3% yr\−1).",
