Erosion's Contribution to Greenhouse Gases
Summary
Monday, December 31, 2001
GHGs (CO2, CH4, and N2O) have increased steadily during the past century.
Soil organic matter (SOM) contains a large reservoir of sources for GHGs.
Human-enhanced erosion through cultivation and land clearing is ubiquitous and increasing.
Erosion accelerates SOM decomposition.
SOM decomposition releases CO2, CH4, and N2O.
Accelerated erosion is a source of GHGs by enhancing SOM decomposition.
