Conteúdo: | This publication presents the contributions of Embrapa and its partner institutions for the advancement of knowledge about GHG emissions in the Brazilian agricultural sector, the result of an integrated work effort that constituted the Agrogases research network ? Carbon Dynamics and Greenhouse Gas Emissions in Brazilian Agricultural, Agroforestry and Forestry Systems. Among the results, the most prominent is the generation of specific values for CH4 and N2O emission factors for Brazilian conditions, which were then compared with the figures presented by the Intergovernmental Panel on Climate Change (IPCC). Methane emission factors were determined in irrigated rice production systems, with possible mitigation associated with the planting system. Other aspects worth noting were the positive nitrogen balance in agricultural systems, especially in no-tillage planting, and the rehabilitation of degraded pastures to promote sequestration of C in soils. In beef and dairy cattle production, emission factors for enteric methane were determined for various dietary conditions, demonstrating that it is possible to significantly reduce the production of this gas per unit of meat produced by improving the quality of the forage. The introduction of forage legumes with an efficient system of obtaining N2 from the air through biological nitrogen fixation is a good strategy to improve not only the productivity of pastures, but also their quality. This strategy, combined with the adoption of the crop-livestock integration system, offers the best prospects for boosting grain and livestock production in a sustainable way, significantly contributing to the mitigation of GHG emissions.
