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 human populations. All quantities of carbon distributed to each gridcell were divided by the total gridcell area, resulting in average carbon fluxes per unit of total area. For derivation of human carbon fluxes at the national 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 human populations and total food supply reported by FAO, on food supply chain losses reported by Gustavsson et al. [2011, 2013], on additional coefficients developed by Wolf et al. [in review], and on respiration quantities reported by West et al. [2009]. References:Gustavsson, J., C. Cederberg, U.
