The aim of this study was to analyse the potential greenhouse gas emissions (GHGE) of locally and regionally produced, alternative protein‐rich feedstuffs (APRFs) which can be utilised in dairy cattle feeding as compared to extracted soybean meal (SBME) in a complete life‐cycle chain for Austria. In addition to GHGE from soil (N2O), from the production of mineral fertilizers and pesticides, industrial processes (oil milling, distillery, and drying plant) and use of fuels, the effects of land use change (LUC) were included in the calculation of GHGE. Currently, SBME, which is mainly imported from South‐America, is the most important protein feedstuff for livestock in Austria, but recently it was started to replace it by APRFs in diets for dairy cows for... |

This study examined the environmental impact of the three common organic pig husbandry systems, indoor (n = 24), partly outdoor (n = 30), and outdoor (n = 10), in eight European countries. Global warming (GWP), acidification (AP), and eutrophication potential (EP) was assessed per 1000 kg pig live weight on 64 farrow-to-finish pig production chains (cradle to farm gate). GWP, AP, and EP varied greatly, and the most important source was feed production, followed by housing. GWP did not differ between systems (p = 0.934), but AP in indoor systems and EP in outdoor systems were higher than in partly outdoor systems (p = 0.006 and p = 0.010, respectively). The higher AP in indoor systems can mainly be explained by NH3 arising from manure spreading, while... |

Der Beitrag stellt einen quantitativen LCA-basierten methodischen Ansatz vor, um wesentliche Aspekte sozialer Nachhaltigkeit von Lebensmittel-Bereitstellungsketten zu analysieren. Dabei wird für alle betrachteten Indikatoren ein gemeinsamer Wirkungsindikatorwert (Zeit je kg Produkt), gewichtet mit Lebens- und Arbeitsqualität von Arbeitsschritten, verwendet. Dies erlaubt eine Integration zentraler sozialer Wirkungen und ermöglicht eine Darstellung von Unterschieden in Lebensmittel-Wertschöpfungsketten, einschließlich Faktoren wie ökologische und herkömmliche Bewirtschaftung, unterschiedliche Arbeitsbedingungen oder Unterschiede bei Mitspracherechten von Arbeitnehmern. |

Organic farming standards regulate allowable nutrient inputs according to the core principles of: reliance on renewable resources, recycling of wastes and by-products of plant and animal origin, and feeding of plants through the soil ecosystem and not through soluble fertilizers, balanced against a goal to produce high quality products with a minimum level of contaminants. These criteria are applied to the list of currently permitted inputs in organic agriculture, known as "Annex 1" of the European Commission Regulation EC No. 889/2008. This list currently excludes some potentially useful sources of societal waste (e.g. some sources of household waste and digestate, sewage sludge), but allows other sources which may pose higher risks according to some... |

The aim of this study was to analyze various Austrian dairy production systems (PS) concerning their greenhouse gas emissions (GHGE) in a life-cycle chain, including effects of land-use change (LUC). Models of eight PS that differ, on the one hand, in their regional location (alpine, uplands and lowlands) and, on the other hand, in their production method (conventional versus organic, including traditional and recently emerging pasture-based dairy farming) were designed. In general, the GHGE-reducing effect of a higher milk yield per cow and year in conventional dairy farming cannot compensate for the advantages of organic dairy production which requires lower inputs. This is shown both for GHGE per kg of milk and GHGE per ha and year of farmland.... |

Regionale Lebensmittel zeichnen sich durch ein hohes Maß an geschlossenen, regionalen Stoff- und Wirtschaftskreisläufe entlang der Wertschöpfungskette (WSK) aus. Sie leisten damit insbesondere auf regionaler Ebene einen Beitrag zur Nachhaltigen Entwicklung und Resilienz. Zur Quantifizierung dieses Beitrags wurde ein Bewertungsmodell entwickelt, welches die Themen regionale Wertschöpfung, regionale und betriebliche Resilienz sowie Produkteigenschaften abdeckt. Bei der Bewertung wird die gesamte Wertschöpfungskette von den landwirtschaftlichen Vorleistungen bis zum point-of-sale mit einbezogen. Das Modell liefert produktbezogene Ergebnisse, die als „regionaler Mehrwert“ bezeichnet werden. Im Folgenden wird das Bewertungsmodell und die damit generierten... |

Phosphorus (P) is an essential element for all living organisms. At the current rate of extraction, global reserves of mineable deposits will be exhausted within the next few centuries. This publication aims to summarize the current knowledge on P recycling for organic farming. The evaluation of recycled P fertilizers (RPFs) includes (i) a chemical characterization, (ii) assessment of their plant P availability and added effects in the soil, (iii) life cycle assessments, (iv) a risk assessment of their long-term impacts on soil pollution, and (v) the compilation of other environmental impacts of different treatment approaches to produce RPFs. The highest nutrient recovery rates for P are achieved by rather simple process approaches of P recycling, while... |
