The dataset contains two files:
File 1 name:		wfwood.tiff
File 1 description:	Raster with the green, blue and green plus blue water footprint in m³ water per m³ roundwood at 30 x 30 arc minutes spatial resolution.
			Raster contains 3 bands:
			Band 1:	Green water footprint in m³ water per m³ roundwood
			Band 2:	Blue water footprint (from capillary rise) in m³ water per m³ roundwood
			Band 3: Green plus blue water footprint in m³ water per m³ roundwood
			NoData value: -9999

File 2 name:		wfwood-country-avg.xlsx	
File 2 description:	Table with the average green, blue and green plus blue water footprint in m³ water per m³ roundwood per country.
			This table has been obtained by taking a roundwood production-weighted average per country of the underlying values at 30 x 30 arc minutes spatial resolution.
			Table contains 5 variables:
			country_code: FAOSTAT country code
			country_name: country name
			wfg_m3m3rw: green water footprint in m³ water per m³ roundwood
			wfb_m3m3rw: blue water footprint in m³ water per m³ roundwood
			wf_m3m3rw: green plus blue water footprint in m³ water per m³ roundwood
