简介: |
Carbon emissions from land-use and land-cover change (LULCC) are part of the human perturbation to the global carbon cycle and started in fact before the Industrial Era when fossil fuel CO2 emissions appeared. Since 1850, estimated cumulative LULCC emissionsrepresent one-third of total cumulative anthropogenic CO2 emissions.However, the uncertainties in LULCC emissions are large due to lack of direct observations. I will address several aspects onhow to reduce the uncertainties in the global LULCC and carbon cycle using models and observations. I will introduce the global land cover changes from the ESA CCI global land cover dataset and methods to estimate LULCC carbon emissions. |
