“…Globally, 130 million ha were deforested between 1990 and 2009, while the areas of cropland and grassland have increased by 11 and 21 million ha, respectively (FAOSTAT, 2013). Annual mean global C emissions from LUC were estimated to be 4.1 Gt CO 2 y À1 between 1870 and 2013 (Le Quéré et al, 2013) and 4.0 Gt CO 2 y À1 between 1980 and 2000 (Houghton et al, 2012). With ongoing concern about global climate change, the effect of LUC on the emission of all these GHGs needs to be critically evaluated.…”
