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.

Several diseases have caused great damage to citrus production worldwide. Among them, Greening is the most feared for its aggressiveness, speed of spread, and a lack of resistant variety. Infected plants goes through a long asymptomatic period (around 6 to 36 months), allowing the permanence of inocullum in the field. This study purpose to evaluate the capability of early diagnosis of spectroscopy at infrared with transformed Fourier (FTIR) for the Greening disease. For both, 60 citrus seedlings were inoculated with Candidatus Liberibater asiaticus (CLas) and 60 healthy seedlings (control) were kept in a greenhouse, which grown under controlled conditions of soil, irrigation and nutrients. Their leaves were measured monthly using FTIR spectroscopy during eight months. The evolution of the bacteria on inoculated plants was monitored by RT-qPCR (real-time quantitative PCR) amplification of CLas sequences. The spectra were analyzed using Principal Component Analysis (PCA). For all the months, it was shown separation between the asymptomatic and healthy leaves, emphasizing that significant chemical changes are occurring before symptomatic phase. Preliminary analyses showed that infected plants suffered a decreasing in concentrations of carbohydrate and chlorophyll. The results also showed that is possible to recognize a typical signature of sick leaf using FTIR spectroscopy, even in symptomatic phase, which must be studied as a feasible tool to develop a methodology for early citrus greening detection.
