The Challenges of Sustainable Forest Operations in Amazonia

Purpose of ReviewThe goal of this review was to determine what constitutes current challenges in effectively implementing sustainable forest operations in Amazonia. Next, succinctly characterize these challenges into comprehensive well-defined areas. Then ascertain the solutions provided in the literature. Lastly, after a thorough assessment, present potential directions to assist foresters, land managers, researchers, and loggers to build a consensus on what is necessary to achieve sustainable forest operations in Amazonia.Recent FindingsIllegal logging is a pervasive threat to the credibility of the forest sector with 38% of all logged area in the Brazilian Amazon illegal, which undermines legitimate logging operations through an unfair competitive advantage. One solution is the application of near infrared spectroscopy which has shown promise in determining species and potentially the region of origin. This same technology is also being refined for utilization in species differentiation between logging residues used in green energy, as some industries are species averse, whereas the same species may still be viable for energy generation. Recent models reveal that in the Brazilian Amazon the logging cycle is too short and the cutting intensity too high. Moreover, tree age estimation, which is difficult in many Amazonian species, can now be determined through radiocarbon analysis to determine sustainable cutting cycles.SummaryWithout increased onsite forest inspections and determination of timber origin, illegal logging will continue unabated. Stand damage from logging can easily be reduced through new models and programs that reduce logging infrastructure coverage. To avoid the depletion of timber stocking, the logging cycle must be increased to coincide with the slow growth realities of many species in the Amazon.

Automated summary

Illegal logging poses a widespread threat to the forest sector in Amazonia, with a significant proportion of logged area being illegal. Near infrared spectroscopy has been identified as a potential solution for species determination and timber origin tracking. In addition, models suggest that the logging cycle in Amazonia is too short and the cutting intensity is too high. Radiocarbon analysis can now be used to estimate tree age and determine sustainable cutting cycles.
