carbon sequestration Flashcards
How does land cover change affect the process of carbon sequestration?
Land cover change affects processes that occur within the carbon cycle, including that of carbon sequestration.
Any change to this process due to land cover change will ultimately effect climate, which then creates feedback loops to influence land cover (a bi-directional relationship)
what is the definition of natural carbon sequestration
the syllabus defines natural carbon sequestration as the process of capture and long term storage of atmospheric carbon dioxide by the natural biogeochemical cycling of carbon
What is the primary cause of deforestation and the subsequent release of carbon into the atmosphere?
The creation of new agricultural land typically requires the clearing of native forests. When trees are cut down and burned or left to decompose, carbon that was previously stored in the fibres of the vegetation is released as CO2 to the atmosphere.
Currently, deforestation and the resulting net carbon source to the atmosphere is occurring primarily in the tropics
What has allowed for natural carbon sequestration in the US and Europe?
Less productive agriculture land in the US and Europe has been allowed to regrow as frorets. This has resulted in the natural sequestration (long term storage) of carbon from the atmosphere, through carbon accumulation in woody biomass and soils.
