Methane and nitrous oxide mitigation in agriculture
This analysis presents cost estimates for mitigating nitrous oxide from cropland soils, and methane from livestock enteric fermentation, manure management and rice cultivation for major world regions. Total estimated global mitigation potential is approximately 64 MtCeq. in 2010 at negative or zero costs, 141 MtCeq. at $200/ITCeq., and up to 168 MtCeq. at higher costs. Costs for individual options range from negative to positive in nearly every region, depending on emission, yield, input, labor, capital cost, and outside revenue effects. Future assessment requires improved accounting for multiple greenhouse gas effects, heterogeneity of emissions and yields, baseline management conditions, identification of options that generate farmer and societal benefits, adoption feasibility, and commodity market effects into mitigation decisions.
