abstract = "Better remote sensing based information on the global distribution
of croplands and pastures is urgently needed. Without reliable
cropland-pasture separation it will be impossible to retrieve
high-quality information on agricultural expansion or land use
intensification, and on related ecosystem service provision. In
this context, the savanna biome is critically important but
information on land use and land cover (LULC) is notoriously
inaccurate in these areas. This is due to pronounced
spatial-temporal dynamics of agricultural land use and spectral
similarities between cropland, pasture, and natural savanna
vegetation. In this study, we investigated the potential to
reliably separate cropland, pasture, natural savanna vegetation,
and other relevant land cover classes employing Landsat-derived
spectral-temporal variability metrics for a savanna landscape in
the Brazilian Cerrado. Spectral-temporal variability metrics were
derived from 344 Landsat images across four footprints between
2009 and 2012. Our results showed a reliable separation between
cropland, pasture, and natural savanna vegetation achieving an
overall accuracy of 93%. There is great potential for expanding
our approach towards large parts of the Cerrado biome and to other
savanna systems which still suffer from inaccurate LULC
information.",
