A controversy re-visited: Is the coccinellid Adalia bipunctata adversely affected by Bt toxins? Organic Eprints
Hilbeck, Angelika; Mc Millan, Johanna M.; Meier, Matthias; Humbel, Anna; Schläpfer-Miller, Juanita; Trtikova, Miluse.
Background: In 2008/2009, Schmidt and colleagues published a study reporting lethal effects of the microbial Bt toxins Cry1Ab and Cry3Bb on the coccinellid biological control organisms Adalia bipunctata. Based on this study, in concert with over 30 other publications, Mon810 cultivation was banned in Germany in 2009. This triggered two commentaries and one experimental study all published in the journal ‘Transgenic Research’ that question the scientific basis of the German ban or claim to disprove the adverse effects of the Bt toxins on A. bipunctata reported by Schmidt and colleagues, respectively. This study was undertaken to investigate the underlying reasons for the different outcomes and rebuts the criticism voiced by the two other commentaries....

Agriculture bio respectueuse du climat: le jeu en vaut-il la chandelle? Organic Eprints
Schader, Christian; Meier, Matthias.
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.

Climate Change Adaptation Through Science-Farmer-Policy Dialogue in Mali Organic Eprints
Bautze, Lin; Nicolay, Gian L.; Meier, Matthias; Gattinger, Andreas; Müller, Adrian.
Climate change increases the number of risks for agricultural production in arid and semiarid regions, especially in Western Africa. Smallholder farmers are particularly vulnerable to climate change risks. These risks affect their socioeconomic situation, as well as the local food sector value chain in general. Therefore, their food security is threatened if smallholder farming structures do not adapt to them. Thus, effective climate change adaptation measures for smallholders are essential and should be implemented without delay. However, success hinges on the acceptance of the promoted measures among various stakeholders. Thus, their acceptance needs to be assessed before promoting. The project “The potential of sustainable land-use systems to promote...

Eckpunkte einer standortangepassten Landwirtschaft in der Schweiz Organic Eprints
Müller, Adrian; Meier, Matthias; Moakes, Simon; Oehen, Bernadette.
In dieser Studie bestimmen wir auf der Basis verschiedener Modellierungsstudien die Eckpunkte einer standortangepassten Landwirtschaft für die Schweiz. Dies bedeutet eine langfristig produktive Landwirtschaft, die umweltverträglich ist und die Lebensgrundlagen nicht zerstört weil sie die lokalen Ressourcen in einer den lokalen Gegebenheiten entsprechend optimalen Weise nutzt. Dies bedeutet insbesondere, dass sie die lokal verfügbaren Kulturlandflächen mit einer Produktionsintensität, die innerhalb der Kapazitätsgrenzen der lokalen Ökosysteme liegt, nutzt. Neben der Nahrungsmittelproduktion erbringt eine solche Landwirtschaft zahlreiche weitere Ökosystemdienstleistungen und unterstützt die Resilienz der Ökosysteme. Dies wird durch die Reduktion der Inputs...

Effect of Three Husbandry Systems on Environmental Impact of Organic Pigs Organic Eprints
Rudolph, Gwendolyn; Hörtenhuber, Stefan; Bochicchio, Davide; Butler, Gillian; Brandhofer, Roland; Dippel, Sabine; Dourmad, Jean Yves; Edwards, Sandra; Früh, Barbara; Meier, Matthias; Prunier, Armelle; Winckler, Christoph; Zollitsch, Werner; Leeb, Christine.
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...

Environmental risk assessment of genetically modified plants - concepts and controversies Organic Eprints
Hilbeck, Angelika; Meier, Matthias; Römbke, Jörg; Jänsch, Stephan; Teichmann, Hanka; Tappeser, Beatrix.
Background and purpose: In Europe, the EU Directive 2001/18/EC lays out the main provisions of environmental risk assessment (ERA) of genetically modified (GM) organisms that are interpreted very differently by different stakeholders. The purpose of this paper is to: (a) describe the current implementation of ERA of GM plants in the EU and its scientific shortcomings, (b) present an improved ERA concept through the integration of a previously developed selection procedure for identification of non-target testing organisms into the ERA framework as laid out in the EU Directive 2001/18/EC and its supplement material (Commission Decision 2002/623/EC), (c) describe the activities to be carried out in each component of the ERA and (d) propose a hierarchical...

Evaluating On-Farm Biodiversity: A Comparison of Assessment Methods Organic Eprints
Gabel, Vanessa M.; Home, Robert; Stöckli, Sibylle; Meier, Matthias; Stolze, Matthias; Köpke, Ulrich.
Strategies to stop the loss of biodiversity in agriculture areas will be more successful if farmers have the means to understand changes in biodiversity on their farms and to assess the effectiveness of biodiversity promoting measures. There are several methods to assess on-farm biodiversity but it may be difficult to select the most appropriate method for a farmer’s individual circumstances. This study aims to evaluate the usability and usefulness of four biodiversity assessment methods that are available to farmers in Switzerland. All four methods were applied to five case study farms, which were ranked according to the results. None of the methods were able to provide an exact statement on the current biodiversity status of the farms, but each method...

Improving Crop Yield and Nutrient Use Efficiency via Biofertilization - A Global Meta-analysis Organic Eprints
Schütz, Lukas; Gattinger, Andreas; Meier, Matthias; Müller, Adrian; Boller, Thomas; Mäder, Paul; Mathimaran, Natarajan.
The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen, to improve water uptake or to act as biocontrol agents. Despite the existence of a considerable knowledge on effects of specific taxa of biofertilizers, a comprehensive quantitative assessment of the performance of biofertilizers with different traits such as phosphorus solubilization and N fixation applied to various crops at a global scale is missing. We...

Klimabilanz im Fricker Langzeitversuch Organic Eprints
Meier, Matthias; Schader, Christian.
Conclusion ❯ Sur l'ensemble de la rotation des cultures, le travail réduit du sol a produit près de 20 % en moins d'émissions de gaz à effet de serre par hectare que le labourage, et près de 75 % de carbone en plus a été stocké à long terme. ❯ Aucune différence entre les variantes d'utilisation des engrais. ❯ Les émissions de N2O produites par le sol sont responsables de 25 à 63 % des émissions de gaz à effet de serre (en fonction des cultures). Le reste provient de la combustion d'énergies fossiles. ❯ Dans le travail réduit du sol, la séquestration du carbonecompense les émissions de gaz à effet de serre produites par le travail des cultures (sur l'ensemble de la rotation des cultures). Cette méthode de culture présente donc un bilan climatique...

Measuring and improving the environmental performance of organic farming Organic Eprints
Müller, Adrian; Meier, Matthias; Schader, Christian; Gattinger, Andreas; Steffens, Markus.
There is a large and growing body of literature comparing the environmental performance of organic and conventional farming in specific settings, either on farm or product level. However, how one assesses ‘environmental performance’ is a complex and multifaceted question, and one-dimensional indicators tend to neglect key aspects of production systems. This chapter evaluates a number of multidimensional methods of assessment, including Life Cycle Assessment, Productivity Analysis, multi-criteria assessment approaches and food systems modelling. It is concluded that the assessment of environmental performance must go beyond the level of production, and address consistency and sufficiency aspects that emerge at the consumption stage. The organic sector has a...

Mitigating the impact of agriculture on air quality and climate change: Solutions for improved Nitrogen management Organic Eprints
Steinemann, Beatrice; Gattinger, Andreas; Krauss, Maike; Berner, Alfred; Leiber, Florian; Maurer, Veronika; Meier, Matthias; Oehen, Bernadette; Bautze, Lin; Niggli, Urs.
Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800 000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century.

Modell zur Quantifizierung des Energieverbrauchs und der Treibhausgasemissionen von Biobetrieben Organic Eprints
Schader, Christian; Meier, Matthias; Kuhn, Till; Jud, Katja; Oehen, Bernadette; Gattinger, Andreas; Stolze, Matthias.
Zusammenfassung Während der Jahre 2009-2011 wurden am FiBL über verschiedene Projekte Grundlagen zur betrieblichen und produktbezogenen Energie- und Klimabilanzierung erarbeitet. Daraus wurde ein Modellansatz entwickelt, mit dem der Energieverbrauch und die Treibhausgasemissionen (THG-Emissionen) auf Betriebsebene abgeschätzt werden können. Aus diesen Vorarbeiten ist 2011 und 2012 das FiBL-Betriebsmodell entstanden, mit dem es möglich ist: 1. detaillierte Klimabilanzen von Schweizer Biobetrieben durchzuführen, 2. zwischenbetriebliche Vergleiche anzustellen und 3. die Auswirkungen von betrieblichen Veränderungen oder Anpassungsstrategien auf die THG-Emissionen zu berechnen. Die grosse Stärke des Betriebsmodells ist seine hohe Flexibilität in Bezug...
