Abstract: The objective of this paper is to evaluate the potential contribution of regionally-specific land use-related activities to the future emissions at 0.5o x 0.5o resolution. We have developed a downscaling framework, which spatially disaggregates future land uses changes based on socioeconomic, biophysical, and biogeochemical factors at 0.5о by 0.5 о resolution. The downscaling framework has been used to calculate greenhouse gas emissions for two IPCC scenarios, A2 and B2. Results indicates that Land uses changes under the A2 scenario contribute significantly to the emissions of CO2, CO, NOx, and NMHCs. Under this scenario land use changes generate 0.8 Gt/yr CO2, 71.1 Tg/yr CO, 1.9 Tg/yr Nox, and 4.9 Tg/yr NMHCs by 2025, which drop to 0.6 Gt/yr, 16.5 Tg/yr, 0.4 Tg/ye, and 1.0 Tg/yr by 2050. Results also indicate that more land will be available for the Agro-Ecological zones, which represent a length of growing period between 120 to 239 days in the future under both scenarios.
