According to the latest report of the Intergovernmental Panel on Climate Change (IPCC), emissions must be cut by 41–72%below 2010 levels by 2050 for a likely chance of containing the global mean temperature increase to 2C°. The AFOLU sector (Agriculture, Forestry and Other Land Use) contributes roughly a quarter (~10–12 PgCO$_{2}$e yr$^{-1}$) of the net anthropogenic GHG emissions mainly from deforestation, fire, wood harvesting, and agricultural emissions including croplands, paddy rice, and livestock. In spite of the importance of this sector, it is unclear where the regions with hotspots of AFOLU emissions are and how uncertain these emissions are. Here we present a novel, spatially comparable dataset containing annual mean estimates of gross AFOLU emissions (CO$_{2}$, CH$_{4}$, N$_{2}$O), associated uncertainties, and leading emission sources, in a spatially disaggregated manner (0.5°) for the tropics for the period 2000–2005. Our data highlight the following: (i) the existence of AFOLU emissions hotspots on all continents, with particular importance of evergreen rainforest deforestation in Central and South America, fire in dry ... mehr
