Abstract

<p> The agriculture and livestock sector accounts for 24% of anthropogenic greenhouse gases in the global warming problem. Therefore, we estimated the emissions of CH₄ and N₂O in the agriculture and livestock sectors in the Latin America region, which have not been studied before, the amount of possible emission reductions, and effective countermeasure technologies. As a result, it is estimated that the emissions of CH₄ and N₂O in the agriculture and livestock sectors in the Latin American region will be 633MtCO₂eq/year in 2050, which is 528MtCO₂eq/year (45.5%) lower than the case where no countermeasures are taken. The study covered 34 countries in the Latin American region, and the top three countries accounted for 71.1% of the reduction. The most effective reduction technology in 2050 was shown to be the change to highly productive livestock species, followed by the highly efficient use of fertilizers.</p>
