Nitrous oxide emission estimation from managed soils in Argentina: Differences between IPCC 2006 guidelines and the IPCC 2019 refinemet
Based on the IPCC 2006 guidelines, the total GHG emission for 2016, in Argentina, were estimated to reach a total net 364 MtCO2eq. Particularly, N2O emissions from managed soils sector represented 12% of total emissions. The IPCC 2019 refinement to the 2006 guidelines for GHG inventories provides an...

| description | Based on the IPCC 2006 guidelines, the total GHG emission for 2016, in Argentina, were estimated to reach a total net 364 MtCO2eq. Particularly, N2O emissions from managed soils sector represented 12% of total emissions. The IPCC 2019 refinement to the 2006 guidelines for GHG inventories provides an up-to-date and robust scientific basis to support the preparation and continuous improvement of estimates. The aims of the present work were to carry out a desk study to estimate nitrous oxide emissions from managed soils, using the IPCC 2019 and to compare this methodology with the one currently used for national GHG inventories (IPCC 2006) in Argentina. The nitrogen sources accounted for GHG emissions were: (i) synthetic fertilizer, (ii) crop residues, (iii) mineralization from soil organic matter, (iv) urine and dung from grazing animals, and (v) organic fertilizer. The adoption of the updated
emission factors from the 2019 IPCC refinement would have a significant impact on the estimation of nitrous oxide (N2O) emissions. Compared to the 2006 IPCC guidelines, the application of these factors in Argentina would lead to decrease emissions from managed soils in 18.95 MtCO2eq, representing a 46% reduction for this category. This reduction would be significant in the greenhouse gases (GHG) inventories of Argentina (by approximately 5%), and for other countries with similar economies. These changes might affect the prioritization of mitigation actions for the analyzed categories, when considering cost and benefits. |

Según las directrices del IPCC de 2006, las emisiones totales de gases de efecto invernadero (GEI) en 2016 se estimaron en 364 MtCO2eq en Argentina, representando el óxido nitroso (N2O) de los suelos gestionados el 12% de estas emisiones. El refinamiento 2019 de las Directrices del IPCC de 2006 para los inventarios de GEI proporciona una base científica sólida y actualizada para respaldar la preparación y la mejora continua de las estimaciones. El objetivo de este artículo es realizar un estudio teórico para estimar las emisiones de óxido nitroso de suelos gestionados, utilizando el refinamiento del IPCC 2019 y compararlo con la metodología utilizada actualmente para los inventarios nacionales de GEI (IPCC 2006) en Argentina. Las fuentes de nitrógeno contabilizadas que generan emisiones de GEI fueron: (i) fertilizante sintético, (ii) residuos de cultivos, (iii) mineralización de materia orgánica del suelo, (iv) orina y estiércol de animales de pastoreo, (v) fertilizante orgánico. La aplicación de los factores del refinamiento del IPCC 2019 tendría un impacto significativo en la estimación de las emisiones de óxido nitroso (N2O). En comparación con las directrices del IPCC 2006, la aplicación de estos factores en Argentina llevaría a disminuir las emisiones de suelos manejados en 18,95 MtCO2eq, lo que representa una reducción del 46% para esta categoría. Esta reducción sería significativa en los inventarios de GEI de Argentina (en aproximadamente un 5%), y posiblemente en los inventarios de GEI de otros países con economías similares. Estos cambios podrían afectar la priorización de acciones de mitigación para las categorías analizadas, al considerar costos y beneficios. Instituto de Suelos Fil: Said, Andrés.
