| Climate change mitigation is urgent and adaptation to climate change is crucial, particularly in agriculture, where food security is at stake. Agriculture, currently responsible for 20-30% of global greenhouse gas emissions counting direct and indirect agricultural emissions), can however contribute to both climate change mitigation and adaptation. The main mitigation potential lies in the capacity of agricultural soils to sequester CO2 through building organic matter. This potential can be realized by employing sustainable agricultural practices, such as those commonly found within organic farming systems. Examples of these practices are the use of organic fertilizers and crop rotations including legumes leys and cover crops. Mitigation is also achieved... |

| Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom. A total of 34 farms were analysed. The assessment was carried out using an attributional approach with system boundaries from cradle to farm gate. In relation to dairy production, a functional unit of 1 kg of energy corrected milk was used. The results gave an average of 1.32 kg CO2 equivalents per kilogramme of energy-corrected milk with standard deviation of 0.22, which is consistent with recent studies. The main contributor to this is enteric... |

| There has recently been an increase in interest in the “public goods” that could be provided by a farm alongside its primary function of agricultural production. This paper reviews recent reports on the topic of public goods and, in particular, the public goods provided by agriculture and then goes on to discuss the development of a tool which can be used to assess the provision of public goods on a farm across a range of areas: soil management, biodiversity, landscape and heritage, water management, manure management and nutrients, energy and carbon, food security, agricultural systems diversity, social capital, farm business resilience, and animal health and welfare. |

| Die Stickstoffüberschüsse in der deutschen Landwirtschaft sind beträchtlich. Der Beitrag stellt dar, welchen Beitrag zum aktiven Wasserschutz eine entsprechende Landnutzung leisten kann. Von den bestimmenden Landnutzungsformen in Deutschland (Ackerland, Grünland, Wald) wurden für den Nährstoff Stickstoff jeweils anhand von vielen in der Literatur dokumentierten Daten Mittelwerte und Schwankungsbreiten für die Bilanzkriterien (Zufuhr, Abfuhr, Saldo) die Nmin-Gehalte im Spätherbst, die Nitratkonzentrationen im Sickerwasser und die Auswaschung ermittelt. |

| Die Landwirtschaft soll Treibhausgasemissionen reduzieren und klimafreundlicher werden. So die Zielsetzung laut Klimastrategie des Bundesamtes für Landwirtschaft. Dass diese Strategie auch ohne gesetzliche Verpflichtungen umgesetzt werden kann, zeigen Marion und Jacques Granges auf der Domaine de Beudon in Fully VS. Das FiBL hat im Auftrag von Bio Suisse für den Bioweinbetrieb eine Klimabilanz gerechnet. |

| Buffer zones were effective in decreasing losses of eroded soil particles, total P and particulate P in surface runoff from fields ploughed in autumn. The retention of DRP was low, the DRP loads to surface runoff might increase on BZs in winter and early spring. The grass should be cut and the swathe removed on the BZs. Innovatons, with them DRP can be retained on BZs especially in winter and spring >StoP. On pasture and in direct drilling, the mean annual DRP load was slightly smaller on the VBZ with native scrubs and herbs compared with NBZ (p=0.05, p=0.07, respectively). There was a significant treatment x season interaction on surface runoff, TP, and DRP and almost significant on total solids (erosion), and PP. |

| Considerable amounts of methane and nitrous oxide were emitted during storage of solid pig manure generated by slurry separation. The production of greenhouse gases inside the heap was found to be heavily influenced by the oxygen accessibility, which again was influenced by length of storage and the distance to the heap surface. This implies that emission of greenhouse gases from stores of solid manure may be heavily influenced by the size of heaps and the length of storage. Attention should therefore be paid to the size of heap and the length of the storage period when composting studies for inventories of greenhouse gas emission are planned or used. |

| Organic farming is perceived as a system with a number of positive impacts on all components of the environment. For more precise assessment of differences in environmental impacts of conventional and organic farming, we need to be able to measure and quantify such impacts. For this the LCA (Life Cycle Assessment) method may be used as a tool. Among other, the LCA method is also an invaluable tool for assessing GHG emissions related to agricultural production. In this paper, the use of LCA for evaluation of GHG emissions from Zea Mays L. growing is presented. The emission load was calculated by the simplified method LCA, impact category: climate change. The calculation was performed by SIMA Pro software with integrated ReCiPe Midpoint (H) method. The... |

| The aim of this study is to illustrate the importance of farm scale heterogeneity on nitrogen (N) losses in agricultural landscapes. Results are exemplified with a chain of N models calculating farm-N balances and distributing the N-surplus to N-losses (volatilisation, denitrification, leaching) and soil-N accumulation/release in a Danish landscape. Possible non-linearities in upscaling are assessed by comparing average model results based on (i) individual farm level calculations and (ii) averaged inputs at landscape level. Effects of the non-linearities that appear when scaling up from farm to landscape are demonstrated. Especially in relation to ammonia losses the non-linearity between livestock density and N-loss is significant (p > 0.999), with... |

| Energy production and energy use in organic agriculture (OA) need to be addressed in order to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Thus, there is an obligation to find consensus between the apparent opposing aims of renewable (bio) energy production and soil fertility in OA. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil fertility. |

| This report was presented at the UK Organic Research 2002 Conference. Land emissions of N2O, CO2 and NH3 have been subject to little study under organic systems, yet form important aspects of sustainability of such systems. We describe innovative methods developed at SAC to assess trace gas emission using both automatic closed chamber systems (intensive, short term monitoring) and manually-operated closed chamber systems (occasional, long term monitoring). Long-term data were collected from organic ley-arable rotation trials in North-east of Scotland. Short term data were collected to show the effect of timing and depth of ploughing-out of the ley phase on gas emissions. Ploughing gave a shortterm stimulation of CO2 and, more markedly, of N2O emission.... |

| Klimaschutz wird die Themen Bodenschutz, Naturschutz, Wasserschutz und Tierschutz zukünftig als weitere zentrale Umweltwirkung ergänzen, um Landwirtschaft umweltfreundlich weiter zu entwickeln und zu vergleichen. Der Biobetrieb weist bei den beiden Treibhausgasen CO2 und N2O große Vorteile auf. Bei CH4 fehlt eine hinreichende Analyse, die Systemunterschiede dürften aber gering und eventuell auch nachteilig für den Biobetrieb sein. Für den Einzelbetrieb sollte die absehbare Wirkung des Klimawandels vor Ort frühzeitig bei allen zukünftigen Entscheidungen für die Betriebsentwicklung, Investitionen und Bewirtschaftung berücksichtigt werden. Ebenso sollte einzelbetrieblich für landwirtschaftliche Höfe, aber auch für Verarbeitungs- und Handelsbetriebe der... |
