| We present the global general circulation model IPSL-CM5 developed to study the long-term response of the climate system to natural and anthropogenic forcings as part of the 5th Phase of the Coupled Model Intercomparison Project (CMIP5). This model includes an interactive carbon cycle, a representation of tropospheric and stratospheric chemistry, and a comprehensive representation of aerosols. As it represents the principal dynamical, physical, and bio-geochemical processes relevant to the climate system, it may be referred to as an Earth System Model. However, the IPSL-CM5 model may be used in a multitude of configurations associated with different boundary conditions and with a range of complexities in terms of processes and interactions.

| Abstract: The objective of this work was to evaluate the quality of pasture and enteric methane (CH4) emission of Curraleiro Pé-duro x Nellore cattle in a pasture of Megathyrsus maximus 'Mombaça', both in full sun and in a consortium with babassu palms (Attalea spp.) in the Amazonian biome. The experimental design was completely randomized, with six steers per system, and the evaluations were done during the dry period (2015) and rainy period (2016). In comparison to forage in the full sun system, forage in the silvopastoral system showed, in the dry period, higher levels of crude protein, ether extract, total digestible nutrient, and in vitro digestible organic matter, and lower levels of dry matter, neutral detergent fiber, and total carbohydrate (TCHO).... |

| Abstract: The objective of this work was to contribute to the establishment of a baseline for the methane emission factor for the management of swine manure, considering the current practice of raw manure storage in two open deposits in parallel, in Southern Brazil. Methane (CH4) emissions were continuously measured in three PVC tanks of 3 m3, during 180 days, in the summer. As the content of volatile solids of pig slurry ran out in approximately 130 days, the CH4 emission factor was calculated as B0= 0.48 m3kg-1VS. Although this value is higher than the B0 estimated by Intergovernmental Panel on Climate Change for Latin America (0.29 m3 kg-1 VS), it is in agreement with the B0 estimated for developed countries (0.45 and 0.48 m3 kg-1 VS, for the US and EU,... |

| Abstract The objective of this work was to investigate the impact of the application of wood biochar, combined with N fertilizations, on N2O-N fluxes, nitrogen availability, and water-filled pore space (WFPS) of a clayey Oxisol under rice (wet season) and common bean (dry season) succession. Manual static chambers were used to quantify N2O-N fluxes from soil immediately after a single application of wood biochar (32 Mg ha-1) and after four crop seasons with N applications (90 kg ha-1 N). Soil ammonium (N-NH4+) and nitrate (N-NO3-) availability, as well as WFPS, was measured together with N2O-N fluxes. There was no interaction between biochar and N fertilization regarding N2O-N fluxes in any of the four seasons monitored, although these fluxes were clearly... |

| Zusammenfassung: In dieser Studie werden Treibhausgasemissionen (THG) aus der deutschen Agrar- und Ernährungswirtschaft analysiert und Möglichkeiten zu ihrer Reduzierung erörtert. Darüber hinaus wird die Eignung von Ökobilanzen für die Bewertung von Produktionsverfahren und Produkten untersucht. In Kapitel 2 werden theoretische Grundlagen für die Umsetzung von Klimaschutzpolitiken erörtert. Als Bilanzierungs- und Analysemethoden werden die Emissionsberichterstattung, die umweltökonomischen Gesamtrechnungen, Ökobilanzen (Life Cycle Assessment) und Carbon Footprints vorgestellt. Es folgt in Kapitel 3 eine Analyse der THG-Emissionen des deutschen Agrar- und Ernährungssektors nach Quellgruppen der Klimaberichterstattung sowie in Bezug auf Produktionsprozesse... |

| The Australian government is introducing a Carbon Pollution Reduction Scheme in 2010, as part of its climate change policy. After 2015 agriculture may be covered by this scheme. This paper examines how different broadacre farming systems may be affected by the policy settings of this scheme. Using the bio-economic farming systems model MIDAS (Model of an Integrated Dryland Agricultural System) the impacts of the Carbon Pollution Reduction Scheme on the profitability of different broadacre farming systems in the southwest of Australia are investigated. Results show a range of profit and enterprise impacts across the various farm types. In a scenario where agriculture is not covered by the scheme, reductions in profit range from 7 to 12 percent, attributable... |

| The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to... |
