Zimmerman, B.L. and C.F. Kormos. 2012. Prospects for sustainable logging in
tropical forests.
62:479-487.
A convincing body of evidence shows that as it is
presently codified, sustainable forest-management
(SFM) logging implemented at an industrial
scale guarantees commercial and biological depletion of high-value timber species within three
harvests in all three major tropical forest regions.
The minimum technical standards necessary for approaching ecological sustainability directly
contravene the prospects for financial profitability.
Therefore, industrial-scale SFM is likely to lead to the degradation and devaluation of primary tropical
forests as surely as widespread conventional
unmanaged logging does today. Recent studies also show that logging in the tropics, even using SFM
techniques, releases significant carbon
dioxide and that carbon stocks once stored in logged timber and slash takes decades to rebuild. These
results beg for a reevaluation of the United
Nations Framework Convention on Climate Change proposals to apply a Reducing Emissions from
Deforestation and Forest Degradation subsidy
for the widespread implementation of SFM logging in tropical forests. However, encouraging models of
the successful sustainable management of
tropical forests for timber and nontimber products exist at local-community scales.
Too little is being done to conserve nature in the tropics
despite its importance for human welfare and biodiversity.
