How can sub-national level information on forest area be used to improve/generate national level estimates?
A4 If boundaries of the sub-national units are consistent and definitions compatible, sub-national level information can be aggregated to generate a composite national level estimate through addition of the sub-national figures. Where definitions/classifications differ, harmonization of national classes or reclassification to the FAR 2005 categories should be done prior to adding the various estimates.
