Does anyone have the actual acreage involved?
Well, a couple of articles I checked were laced with panicky jibber jaber, but no numbers for this year, only the typical "In the last 50 years..." which is a typical time stretch designed to inflate the numbers.
About as close as I have been able to get to any figures is this:
Meanwhile, as of August 16, a NASA analysis suggested that "total fire activity across the Amazon basin has been close to the average in comparison to the past 15 years". NASA noted that the Amazon spreads across several countries.

Increased agricultural and mining activity (better accessibility in some areas, and exposure of resources).
Archaeological discoveries, previously masked by foliage, some new finds will come to light after the fires burn out. These, too, will be more accessible by air (helo), and if significant enough, airstrips or roads may be built to access them further.
Nutrients will wash down the Amazon, eventually reaching the ocean and causing an increase in the phytoplankton count offshore, increasing oceanic oxygen production, and the soil in the rain forest will have new growth, also generating O2. There will be increased turbidity in tributaries until this happens, from runoff and erosion of soil.
More varied environments (non canopy jungle) will cause greater variation in habitat, and that will be filled by organisms which are best adapted to that habitat, increasing localized faunal biodiversity. (yeah, I thought that was a good thing)
