abstract = "This letter uses satellite remote sensing to examine patterns of
cropland expansion, cropland abandonment, and changing cropping
frequency in Mato Grosso, Brazil from 2001 to 2011. During this
period, Mato Grosso emerged as a globally important center of
agricultural production. In 2001, 3.3 million hectares of
mechanized agriculture were cultivated in Mato Grosso, of which
500 000 hectares had two commercial crops per growing season
(double cropping). By 2011, Mato Grosso had 5.8 million hectares
of mechanized agriculture, of which 2.9 million hectares were
double cropped. We found these agricultural changes to be
selective with respect to land attributes - significant
differences (p<0.001) existed between the land attributes of
agriculture Versus non-agriculture, single cropping Versus double
cropping, and expansion Versus abandonment. Many of the land
attributes (elevation, slope, maximum temperature, minimum
temperature, initial soy transport costs, and soil) that were
associated with an increased likelihood of expansion were
associated with a decreased likelihood of abandonment (p<0.001).
While land similar to agriculture and double cropping in 2001 was
much more likely to be developed for agriculture than all other
land, new cropland shifted to hotter, drier, lower locations that
were more isolated from agricultural infrastructure (p<0.001). The
scarcity of high quality remaining agricultural land available for
agricultural expansion in Mato Grosso could be contributing to the
slowdown in agricultural expansion observed there over 2006 to
2011. Land use policy analyses should control for land scarcity
constraints on agricultural expansion. © 2014 IOP Publishing
