abstract = "In this study, we examine the hypothesis of a forest transition in
an area of early expansion of the agricultural frontier over the
Brazilian Atlantic Forest in the south-central part of the State
of S{\~a}o Paulo. Large scale land use/cover changes were
assessed by integrating Landsat imagery, census data, and
landscape metrics. Two Landsat multi-temporal datasets were
assembled for two consecutive periods19952006 and 20062013to
assess changes in forest cover according to four classes: (i)
transition from non-forest cover to planted forest (NF-PF); (ii)
transition from non-forest to secondary (successional) forest
(NF-SF); (iii) conservation of planted forest (PF) and (iv)
conservation of forest remnants (REM). Data from the two most
recent, 1995/96 and 2006 agricultural censuses were analyzed to
single out major changes in agricultural production. The total
area of forest cover, including primary, secondary, and planted
forest, increased 30% from 1995 to 2013, whereas forest planted in
non-forest areas (NF-PF) and conservation of planted forest (PF)
accounted for 14.1% and 19.6%, respectively, of the total forest
area by 2013. Such results showed a relatively important forest
transition that would be explained mostly by forest plantations
though. Analysis of the landscape metrics indicated an increase in
connectivity among forest fragments during the period of study,
and revealed that nearly half of the forest fragments were located
within 50 m from riverbeds, possibly suggesting some level of
compliance with environmental laws. Census data showed an increase
in both the area and productivity of sugarcane plantations, while
pasture and citrus area decreased by a relatively important level,
suggesting that sugarcane production has expanded at the expense
of these land uses. Both satellite and census data helped to
delineate the establishment of two major production systems, the
first one dominated by sugarcane plantations approximately located
in the NE part of the study area, and a second one concentrating
most of the forest plantations in the SW portion of the study
area, where most of the forest transition could be observed.",
