Hotspots of gross emissions from the land use sector: patterns, uncertainties, and leading emission sources for the period 2000–2005 in the tropics por Román Cuesta, Rosa María, Rufino, Mariana C., Herold, Martin, Butterbach-Bahl, Klaus, Rosenstock, Todd S., Herrero, Mario, Ogle, Stephen Michael, Li C, Poulter, B., Verchot, Louis V., Martius, Christopher, Stuiver J, Bruin, S. de

“…Our data highlight the following: (i) the existence of AFOLU emissions hotspots on all continents, with particular impor- tance of evergreen rainforest deforestation in Central and South America, fire in dry forests in Africa, and both peat- land emissions and agriculture in Asia; (ii) a predominant contribution of forests and CO2 to the total AFOLU emis- sions (69 %) and to their uncertainties (98 %); (iii) higher gross fluxes from forests, which coincide with higher uncer- tainties, making agricultural hotspots appealing for effective mitigation action; and (iv) a lower contribution of non-CO2 agricultural emissions to the total gross emissions (ca. 25 %), with livestock (15.5 %) and rice (7 %) leading the emissions. …”
