REVIEWING THE ROLE OF TERRESTRIAL ECOSYSTEMS ON THE CARBON SEQUESTRATION
In the light of increasing evidences that a large part of global climate change in the last 200 years originates from human activities, the scientific community has been intensifying the research effort on understanding global warming processes. Carbon sequestration has been appointed as a alternative to mitigate carbon dioxide emissions, being considered in international agreements as the Kyoto Protocol. The analyses of the terrestrial ecosystem potential of carbon sequestration are largely punctual and fragmented. Integrated analyses, discussing processes involved in the biogeochemical cycle of green house gases, are scarce in the literature. Aiming at expanding the discussion on the subject, a deep analysis was made of the terrestrial ecosystem role on CO2 (the major green house gas) balance in the atmosphere was made, emphasising the potentialities and limitations of mitigating activities related to land use changes, in the Kyoto Protocol scope. The evidences led to the conclusion that, if the present patterns of fossil fuel consumption was maintained, carbon fixation in terrestrial ecosystems would be inefficient and innocuous to mitigate problems caused by CO2 accumulation in the atmosphere. Some considerations on processes involved and implications for policy makers are presented, emphasising the necessity of constant search for renewable energy sources.
