Forecast deforestation calculated using minimum (29%) and maximum deforestation (58%) historically registered along the three main roads already paved in the
Amazon.
This section has already been paved in 1997/98.

the highway recovery and pavement, foreseen in the
Avança Brasil Programme.
Among the predominant forces that will have a crucial
role in regional development and will determine
possible scenarios in the region it is worth mentioning
the proposed integration and development policy that
will allow continuity of construction of the paved
highways. This will expand the agriculture frontier and
deforestation, configuring a Scenario of Conventional
Development. The main characteristic of such scenario
is its high likelihood to replicate and even expand the
patterns of occupation and development that took place
in the last decades by means of plans geared towards
economic growth and exploitation of natural resources
of the region.
