Description

  • This paper treats the question if the interaction of anthropogenic and natural threats on the Amazon forest may lead to a tipping point in the near future.
  • Global markets demand increasing supplies of biofuels and animal rations and thus economically incentivize large scale forest clearing due to a growing profitability of land uses which depend on deforestation. Furthermore, there are positive feedbacks among drought, forest fire and economic activities.
  • Human land use and its expansion in the Amazon forest often induce fire or increase the susceptibility of forests. Forest fragmentation and selective logging further degrade forests and are factors which change the structure of the forest in the long term, potentially turning it into low-stature ecosystems where fires easily ignite and spread. Except from the effect from fires, climate change might reduce the amount of rain in the Amazon. These characteristics that may trigger forest degradations play an increasingly important role in the Amazon forest.
  • The authors suggest that the interaction of the above-mentioned factors may lead to a large-scale forest dieback, for example a deforestation of about 31% of the Amazon closed-canopy forest formation.
  • Several suggestions are provided on how to prevent this scenario. First, farmers would have to use fire more cautiously in landscape management. Second, the authors suggest further implication of certification and sustainable land use crediting systems and third, a restriction of agriculture and livestock production in the Amazon forest region. This should be accompanied by the expansion of protection zones and incentives for local people and governments from programs like UN REDD+ to further protect forested areas.
