Description:
It is over three decades since a large terrestrial carbon sink ( S T ) was first reported. The magnitude of the net sink is now relatively well known, and its importance for dampening atmospheric CO 2 accumulation, and hence climate change, widely recognised. But the contributions of underlying processes are not well defined, particularly the role of emissions from land-use change ( E LUC ) versus the biospheric carbon uptake ( S L ; S T = S L − E LUC ). One key aspect of the interplay of E LUC and S L is the role of agricultural processes in land-use change emissions, which has not yet been clearly quantified at the global scale. Here we assess the effect of representing agricultural land management in a dynamic global vegetation model. Accounting for harvest, grazing and tillage resulted in cumulative E LUC since 1...
