Burkina Faso CR timeseries #53

Closed JGuetschow closed 5 months ago

JGuetschow commented 1 year ago

Burkina Faso has 0 / almost 0 values in UNFCCC DI data for some categories. Check where they come from and see if they need to be removed.

The (almost) 0 values in 1.A for CH4 and N2O are not consistent with the reported CO2 emissions. CH4 emissions from agriculture excluding livestock are very low (compared to FAO, EDGAR and the 1994 value) for 2008 - 2017 which is consistent with the data in BUR1 where the only CH4 source is rice cultivations.

There are no new submissions available thus we have no alternatives for the data. The 1994 values come from NC1. Emissions factors use there are consistent with other sources. NC1 contains some of the tables used to calculate the emissions factors and while I could find some errors, none impact the emissions enough to explain the low CH4 emissions in 1.A. The low CH4 and N2O emissions compared to later years might originate from different activity data on biomass use. While NC3 states that 82% of energy supply come from biomass the fraction is below 20% for NC1 which provides the 1994 data. A reason for this discrepancy could be that emissions from firewood used for e.g. cooking is listed in the energy sector in NC3 while they seem to be included in the LULUCF sector in NC2. due to these discrepancies and unclarities we will remove data for 1994 in future versions of PRIMAP-hist
