| description | We compared the balance of greenhouse gasses (GHG) of two contrasting livestock production models of the Salado river basin, Buenos Aires province. One model was characterized by the predominance of native grassland in good condition because of the application of controlled grazing (MP 1) and the other model by a larger surface of cultivated pastures and annual forage crops, higher stocking rate and beef production (MP 2). We applied the IPCC (Intergovernmental Panel on Climate Change) methodology for estimating primary emissions. We incorporated the estimation of secondary emissions and the gain or loss of soil carbon of to the GHG balance. Total emissions were higher in MP 2 than MP 1 (4500 vs. 2273 kg CO2 eq. ha-1 year-1 respectively, p<0,01). MP 1 sequestered carbon at a rate of 1851 kg CO2 eq. ha-1 year-1, while MP 2 emitted carbon at a rate of 601 kg CO2 eq. ha-1 year-1. GHF balance was ten times more negative for MP 2 than MP 1, whose balance resulted neutral. Livestock systems of Salado river basin with predominance of native grassland in good condition are able to mitigate the effect of global warming. |

Livestock systems of Salado river basin with predominance of native grassland in good condition are able to mitigate the effect of global warming. Se comparó el balance de gases efecto invernadero (GEI) de dos modelos de producción ganadera de la cuenca del río Salado, provincia de Buenos Aires. Uno, caracterizado por el uso predominante de pastizal natural en buena condición debido al pastoreo controlado (MP 1), y otro por una mayor superficie de pasturas y cultivos forrajeros, mayor carga animal y producción de carne (MP 2). Se estimaron las emisiones primarias según el IPCC (Panel Intergubernamental del Cambio Climático). Al balance de GEI se incorporaron las estimaciones de las emisiones secundarias y de la ganancia o pérdida de carbono del suelo. Las emisiones resultaron mayores en el MP 2 que en el MP 1 (4500 vs 2273 kg CO2 eq. ha-1año-1 respectivamente, p<0,01). El MP 1 secuestró carbono como carbono orgánico del suelo a una tasa de 1851 kg CO2 eq. ha-1 año-1, mientras que el MP 2 emitió carbono a una tasa de 601 kg CO2 eq. ha-1 año-1. El balance de GEI fue diez veces más negativo en el MP 2 que en el MP 1, cuyo balance resultó neutro. Los sistemas pastoriles de esta región con predominio de pastizal natural bajo pastoreo controlado pueden mitigar los efectos del cambio climático.
