abstract = "This research aims to understand the difference of major
land-cover change results caused in various time periods and to
examine the impacts of human-induced factors on land-cover changes
along the TransAmazon Highway region. The Landsat Thematic Mapper
and Operational Land Imager data from 2011, 2014, and 2017 and our
previous land-cover classification results in 1991, 2000, and 2008
were used to examine land-cover dynamics. A classification system
consisting of five land-cover classes primary forest (PF),
secondary forest (SF), agropasture (AP), urban area, and water
were chosen. The hierarchical-based classification method was used
to generate land-cover classification results, and the
post-classification comparison approach was used to produce
detailed from-to conversions for each detection period. The
emphasis was on deforestation of PF, dynamic change of SF and AP,
and urbanization over time. The impacts of human-induced factors
such as population and economic conditions on urban expansion, AP
expansion, and deforestation were examined. This research
indicated that selection of a suitable time period was critical
for effectively detecting land-cover changes; that is, too long
time period (i.e., 9 years) cannot accurately capture some
land-cover changes such as the AP and SF in this research.
Although deforestation the conversion from PF to SF and AP
accounted for a large proportion of land-cover changes, the
changes between SF and AP became more important than PF
conversion, and required a short time period (i.e., 3 years here)
for effectively reflecting their dynamics. Human-induced factors
play important roles in deforestation, dynamic changes between AP
and SF, and urbanization.",
