abstract = "The unavoidable diet change in emerging countries, projected for
the coming years, will significantly increase the global
consumption of animal protein. It is expected that Brazilian
livestock production, responsible for close to 15% of global
production, be prepared to answer to the increasing demand of
beef. Consequently, the evaluation of pasture quality at regional
scale is important to inform public policies towards a rational
land use strategy directed to improve livestock productivity in
the country. Our hypothesis is that MODIS images can be used to
evaluate the processes of degradation, restoration and renovation
of tropical pastures. To test this hypothesis, two field campaigns
were performed covering a route of approximately 40,000 km through
nine Brazilian states. To characterize the sampled pastures,
biophysical parameters were measured and observations about the
pastures, the adopted management and the landscape were collected.
Each sampled pasture was evaluated using a time series of MODIS
EVI2 images from 2000-2012, according to a new protocol based on
seven phenological metrics, 14 Boolean criteria and two numerical
criteria. The theoretical basis of this protocol was derived from
interviews with producers and livestock experts during a third
field campaign. The analysis of the MODIS EVI2 time series
provided valuable historical information on the type of
intervention and on the biological degradation process of the
sampled pastures. Of the 782 pastures sampled, 26.6% experienced
some type of intervention, 19.1% were under biological
degradation, and 54.3% presented neither intervention nor trend of
biomass decrease during the period analyzed.",
