| Many farm sustainability assessments use multi-criteria methods for aggregating indicators based on performance scores and importance weights. One of these is the SMART-Farm Tool, which measures the degree of goal achievement of farms across 327 indicators nested within 4 sustainability dimensions, 21 themes and 58 sub-themes of the FAO-SAFA Guidelines (Sustainability Assessment of Food and Agriculture). This study aims to improve the empirical foundation of the SMART-Farm Tool by (i) evaluating the uncertainty of indicator weights obtained via expert opinion and (ii) integrating this uncertainty into SMART assessment results. An adapted Delphi process was implemented, involving a group of 67 experts from 21 countries divided into thematic and regional... |

| Contexte La rentabilité d'une exploitation est une condition essentielle pour assurer la réussite de la culture sans labourage dans la pratique. Question expérimentale Dans quelle mesure le travail réduit du sol se distingue t-il du labourage sur le plan des finances et de la gestion du travail? Conclusion �Dans l'essai de longue durée à Frick, le travail réduit du sol affiche de meilleurs résultats que le labourage. Les coûts de production étant presque identiques, le rendement est le critère de jugement décisif. Après trois ans, les premiers résultats des exploitations pratiques ne confirment toutefois pas encore les avantages économiques du travail du sol sans labourage. |

| This paper aims to present the results of an expert and stakeholder based Delphi approach for analysing the performance of Swiss organic agriculture in terms of sustainability. We analysed four different production systems: Bio Suisse standards, public organic standards, integrated farming and farming according to Swiss cross compliance standards. The study illustrated that none of the farming systems performs 100% sustainable against any of the indicators. However, organic production showed an about 1-20% better performance than conventional and integrated systems. Particularly high scores were achieved for product quality, animal welfare, and biodiversity, while performing below average regarding resource use, food security and climate change. We... |

| This paper presents results of an on-farm biodiversity assessment of 45 organic arable farms in eastern Austria (region Weinviertel). The core of the assessment method consists of 99 parameters concerning agricultural practices and semi-natural habitats and their impacts on genetic diversity, habitat diversity and species diversity of eleven indicator species groups. For each farm, a biodiversity performance score was calculated ranging from 0 to 100 %, where 100 % would be reached with the highest possible scores for all parameters. The biodiversity assessment of the 45 organic arable farms revealed big between-farm differences in the biodiversity performance (16.8 to 50.6 %; Ø 32.8 ± 6.1 %). While 32 farms for example achieved biodiversity scores > 40... |

| Quantitative sector models are an essential tool to forecast the sector-wide economic effects of agricultural policies. However, to cover ecological effects with economic sector models is still a methodological challenge. This poster describes a promising approach, which is currently implemented at the Research Institute of Organic Agriculture (FiBL) to meet this challenge. CH-FARMIS is a sector consistent farm group model, which is able to forecast economic impacts of policies on farm, regional and sector-level. In a flexible way, CH-FARMIS is able to split up the farm sector in farm groups according to various characteristics (region, farming system, farm type, etc.). CH-FARMIS is based on positive mathematical programming (PMP) to allow for a realistic... |

| The aim of this PhD thesis was to calculate the cost-effectiveness of organic farming in achieving environmental policy targets compared to single-agri-environmental policies. Using a theoretical model, it was demonstrated that financial support for organic farming does not in principle contradict the Tinbergen Rule, even if there are other targeted policy measures which are more cost-effective in achieving specific environmental goals. Hence, organic farming should be included as an option within a mix of other policies as long as its costeffectiveness with respect to the overall set of policy goals is superior to that of a combination of other policy instruments. The cost-effectiveness of agri-environmental policies can be understood as a function of... |

| In many countries, cotton is traditionally intercropped with other plants in order to increase yields and to control pests. We tested the effects of intercropping cotton (Gossypium barbadense L.) and basil (Ocimum basilicum L.) during one field season on pest infestation, yields, and economical parameters in the Governorate of Fayoum, Egypt. Basil, which is known for its repellent effect on various insect pests, was mixed with cotton in three different intercropping rates (no, medium and high basil area fraction) and two row distances (60 and 90 cm) using a substitutive design with four replicates. Compared with the non-intercropped plots, cotton-basil intercropping significantly reduced total pest infestation and led to a 50% reduced abundance of the pink... |

| Unsere Ernährung ist eng mit gesellschaftlichen Aspekten verknüpft. Von der Nahrungsmittelproduktion gehen erhebliche ökologische Wirkungen aus. Das Forschungsprojekt beleuchtet das Ernährungssystem in der Stadt näher und untersucht das Potential für eine nachhaltigere Gestaltung. Im ersten Projektteil wurden die Institutionen, Organisationen und Initiativen identifiziert, die im Ernährungssystem eine Rolle spielen und strategische und rechtliche Dokumente analysiert, die darauf Einfluss nehmen. Die Ergebnisse sind im Folgenden dargestellt. Das Ernährungssystem einer Stadtregion umfasst alle Prozesse, die Lebensmittel von der Produktion über Verarbeitung, Transport, Handel, Konsum bis zur Entsorgung von Lebensmittelresten (und Food Waste) in dieser Stadt... |

| The need for more sustainable production and consumption of animal source food (ASF) is central to the achievement of the sustainable development goals: within this context, wise use of land is a core challenge and concern. A key question in feeding the future world is: how much ASF should we eat? We demonstrate that livestock raised under the circular economy concept could provide a significant, nonnegligible part (9–23 g/per capita) of our daily protein needs (~50–60 g/per capita). This livestock then would not consume human‐edible biomass, such as grains, but mainly convert leftovers from arable land and grass resources into valuable food, implying that production of livestock feed is largely decoupled from arable land. The availability of these biomass... |

| The request for quantitative tools for ecological-economic impact assessment of agricultural policies has increased in recent years, due to i) improved impact assessment and policy evaluation standards of the new agricultural support schemes (European Commission, 2004) and ii) the improved methodological and technical potentials in the field of sector modelling (Heckelei, 2002). Switzerland, as a non-EU member, has introduced cross-compliance rules already in 1998 and linked a bulk of further ecological direct payments to specific farm management restrictions. While the whole direct payment system has been subject to an official evaluation process (Flury, 2005), especially the question for the cost-effectiveness of extensification policies has not been... |

| Background Dietary patterns have manifold impacts on the environment. • However, studies that assess dietary patterns operate with varying methodological approaches and underlying assumptions, which evoke different, and occasionally even contradicting, results. • This leads to uncertainty regarding what should or should not be eaten, especially with regard to animal-source food (ASF) and production types (e.g. conventional or organic). • Therefore, to adequately interpret results, it is necessary to interpret these in the context of the respective methods used and assumptions made. |

| Dietary patterns have manifold impacts on human health and the environment. Impact assessments are employed to compare impacts of single food items or of diets as a whole, either in their current state or for theoretical scenarios. However, conclusions from impact assessments focusing on theoretical scenarios are diverse, and occasionally even contradicting. The role of animals and types of production are key aspects of these discussions. Therefore, the aim of this study is to analyse the methodological choices that cause these differing conclusions. We find that consideration of food-system-wide consequences of dietary change in the impact assessment, differentiation between land use categories, and production units are central for determining which... |
