West, Yannick L. Le Page, G. Page Kyle, Xuesong Zhang, G. James Collatz, Marc L. Imhoff. Biogenic carbon fluxes from global agricultural production and consumption. Submitted to Global Biogeochemical Cycles. NCO: 4.3.7 comment: These data represent gridded annual (2005 to 2011) carbon fluxes associated with global livestock, summed over all livestock types. For derivation of livestock carbon fluxes at the subnational level and distribution at the 0.05 degree x0.05 degree gridcell level, see Wolf et al. [in review]. These flux estimates were based on livestock populations reported by FAO, on coefficients provided by the IPCC, and on additional coefficients developed by Wolf et al. [in review]. The method subtracts estimated enteric fermentation methane emissions, manure production, and milk and egg production from total feed intake to obtain the quantity of carbon respired as carbon dioxide, and subtracts manure management methane emissions from total manure production to estimate carbon dioxide emissions due to manure management. Annual fodder (i.e. feed provided to animals by humans) intake per nation was derived from i) FAO reports of available market feeds and ii) hay and fodder crop harvests, and iii) estimated crop residues collected for feed [Krausmann et al., 2008; Wolf et al., in review]. Forage intake (i.e. grazing and/or scavenging by ranging animals) was estimated as the difference between total feed intake and fodder intake. Coefficients used and detailed information can be seen in Wolf et al. [in review]. References: Krausmann, F., K.-H. Erb, S. Gingrich, C. Lauk, and H.
