| O objetivo deste trabalho foi avaliar o efeito de plantas de cobertura em cultivo consorciado de maracujá, abacaxi, mandioca e milho sobre a atividade biológica do solo em período chuvoso e de estiagem. O experimento foi conduzido em Rio Branco, Acre, em um ARGISSOLO AMARELO Alítico plíntico. O delineamento experimental utilizado foi o de blocos casualizados completos com parcelas subdivididas e quatro repetições. Nas parcelas foram estudadas épocas de avaliação (março, maio, agosto e outubro de 2011) e, nas subparcelas, plantas de cobertura [kudzu tropical (Pueraria phaseoloides), crotalaria (Crotalaria espectabilis), amendoim forrageiro (Arachis pintoi), feijão de porco (Canavalia ensiformis) e plantas espontâneas]. Foram avaliadas respiração (edáfica e... |

| This work describes a way of splitting emission intensity from enteric fermentation and manure decomposition of a beef cattle production system as a product of performance ratios inspired by DuPont identity used for financial performance analysis (MATT, 2016). Selected production systems identified by the PECUS project were compared through these performance ratios in order to evaluate if they can help on identifying opportunities for the reduction of CO2-e emission intensity. |

| Embrapa?s PECUS project aims to estimate greenhouse gas emissions (GGE) and recommend technological solutions for reducing CO2-e emission intensity from beef cattle production systems. PECUS project identified 23 typical production systems that represent most of the Brazilian beef cattle production and defined mathematical models for their technical and economic performance and CO2-e emission intensity. Choosing the right performance indexes can help to compare different production systems and identify opportunities for improvement. This work describes a way of splitting emission intensity from enteric fermentation and manure decomposition of a beef cattle production system as a product of performance ratios inspired by Du- Pont identity used for financial... |

| The sustainable intensification of production systems will play a prominent role in the future agenda of public research and development institutions. Brazil has made substantial progress over the past few years in the use of sustainable technologies and systems integration. In the last 30 years, the country has developed a sustainable production model that integrates agricultural, livestock, and forestry production in the same area. The Integrated Crops-Livestock-Forestry (ICLF), already occupies approximately 17 million hectares throughout the national territory and has been expanding. Research data show that it is possible to produce, sustainably and competitively, grains, pasture, wood, and meat in the same area. Thus, the ABC Plan and its second... |

| This analysis estimates the profitability of restoring wetlands for the sale of carbon offsets. Results indicate that about 7% to 12% of the recently restored grassed wetlands of the prairie pothole and high plains regions and 20% to 35% of the forested wetlands of the Mississippi alluvial valley and Gulf-Atlantic coastal flats regions could have carbon offset values that exceed the cost of restoring the wetland and the opportunity cost of moving the land out of agricultural production. Given the uncertainties, the analysis applies conservative estimates of wetlands’ costs, offset prices, and wetlands’ effects on greenhouse gases. |
