| Conclusion of chapter 2: "Organic Farming and the Environment" 7 Conclusion The findings of this study show that organic farming provides a wide range of environmental services. The main results may be summarised as follows: 1. Organic matter content is usually higher in organically managed soils indicating a higher fertility and stability of organic soils, thus reducing the risk of erosion. 2. Organically farmed soils have significantly higher biological activity and a higher total mass of micro-organisms. As a consequence of the higher activity of micro-organisms, in organically managed soils nutrients are recycled faster and soil structure is improved. 3. Organic farming poses no risk of ground and surface water pollution through synthetic... |

| Die Artenvielfalt an Pflanzen und Wildtieren und die Vielfalt der Landschaften werden zunehmend durch die sich ausbreitende intensive Landwirtschaft bedroht. Zwar gibt es europäische und nationale Agrarumweltprogramme, die dem entgegenwirken wollen. Sie werden aber zu wenig effizient umgesetzt. Ungenügendes ökologisches Fachwissen und zu wenig ökologisch ausgerichtete Beratung gehören zu den Hauptgründen für die schlechte Umsetzung dieser Programme. Der biologische Landbau geht im Gegensatz zur konventionellen, industriellen Landwirtschaft sehr schonend mit natürlichen Ressourcen um und eignet sich daher besonders zur Förderung einer reichhaltigen Kulturlandschaft mit einer grossen Arten- und Lebensraumvielfalt. Biolandbau kombiniert mit... |

| Das Merkblatt hilft Beratungskräften, Landwirtinnen und Landwirten sowie weiteren landwirtschaftlichen Akteuren bei der Umsetzung der neuen Biodiversitätsförderfläche Blühstreifen für Bestäuber und andere Nützlinge. Das Dokument beschreibt den kulturspezifischen Nutzen der Flächen, deren Anlage, Pflege und Aufhebung. Zudem werden Empfehlungen zur optimalen Umsetzung formuliert, damit die erwartete Leistung der Bestäuber und Nützlinge auch langfristig erbracht werden kann. |

| In ecological cross compliance, farmers have to meet environmental standards in order to qualify for area-related direct payments. Because this is a strong financial incentive, cross compliance is a potentially powerful policy instrument. We monitored the effectiveness of cross compliance in promoting biodiversity on grassland and on arable land in Switzerland over 8 years. We observed measurable benefits for flora, butterflies, ground beetles, and spiders, in terms of species numbers and/or community composition. However, populations of threatened species showed no signs of benefit. While cross compliance has been in force in Switzerland for almost a decade, it has only recently been introduced in the neighbouring European Union. We argue that – provided... |

| Die Unterengadiner Kulturlandschaft hat in der Schweiz eine einmalige Stellung was deren Artenvielfalt und Vielfalt an wertvollen Lebensräumen betrifft. In den teilweise noch traditionell genutzten Wiesen kommen Pflanzen- und Tierarten vor, die sonst in der Schweiz nur noch an wenigen Standorten zu finden sind. Heutzutage wirtschaften mehr als 80 % der Unterengadiner Landwirte nach den biologischen Richtlinien. Dieses naturnahe Bewirtschaftungssystem hat ein beträchtliches Potential in Kombination mit naturnahen Flächen eine reichhaltige Flora und Fauna zu erhalten. Aber auch die biologisch wirtschaftenden Landwirte stehen zunehmend unter einem ökonomischen Druck. Deshalb ist in Zukunft mit tief greifenden Veränderungen in der Landwirtschaft zu Ungunsten... |

| Spiders from ecological compensation areas in the Swiss cantons Aargau and Schaffhausen (Arachnida: Araneae) - with remarks on Phrurolithus nigrinus (Corinnidae). The dpider fauna of open habitats adjacent to arable land was investigated in northern Switzerland. The three habitat types were (1) herbaceous edges of fields (Sa), (2) fallow land sowed with flowers (BB), and (3) grass borders of fields (GS). Four funnel pitfall traps (10 cm diameter) were used to catch spiders in three stripe-types in two geographical regions in two years over 5 weeks in May and June: in total 12 sets of data. Spider species typical for open habitats were dominant, mostly lycosids (6 of 10 most active species). The results were analysed together with environmental factors... |

| Organic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. Growing flowers in order to gain more natural enemies, and hence less pests is a technique called Functional Agro-Biodiversity (FAB). Ongoing research in this CORE Organic Plus project aims to collect existing knowledge and generate new knowledge in order to use FAB successfully in orchards. |

| Although the European organic agriculture movement was founded by Rudolf Steiner and Hans Mueller in the years between 1924 and 1940, it was not until the 1980s that pest management researchers began to develop strategies to control pests in organic systems. Today, insect pest management in organic agriculture involves the adoption of scientificallybased and ecologically sound strategies as specified by international and national organic production standards. These include a ban on synthetic insecticides and, more recently, on genetically modified organisms (GMOs). The first phase of an insect pest management program for organic systems is the adoption of cultural practices including diverse crop rotation, enhancement of soil quality by incorporation of... |

| In dieser Arbeit wurden die Auswirkungen unterschiedlicher traditioneller (konventionell, integriert) und biologischer (organisch-biologisch, bio-dynamisch) Anbausysteme auf die epigäischen Nutzarthropoden und die Regenwurmfauna untersucht. Alle vergleichenden Erhebungen wurden in geregelten Ackerfruchtfolgen durchgeführt. Einerseits waren dies Untersuchungen im DOK-Langzeit-Exaktparzellenversuch in Therwil (Teil A), und andererseits stand danach die Analyse der Praxissituation im Rahmen von Paarbetriebsvergleichen unter Berücksichtigung des Umfeldes der Produktionsflächen (Teil B) im Vordergrund. Es wurden stets der Versuchsanlage angepasste Standardmethoden angewandt. Die Nutzarthropoden wurden mit Trichterbodenfallen (Lebendfang im DOK-Versuch; mit... |

| Despite the introduction of agri-environmental schemes, no general increase of farmland biodiversity in Europe has been observed. Farmers take decisions about the implementation of agri-environmental schemes at the farm scale, and it is thus highly relevant to assess the relationship between farm management and biodiversity at this scale to increase the effectiveness of agri-environmental schemes. The present study quantifies to what extent and with which practices farmers can influence biodiversity on their farm and to what extent conditions outside farmers’ control may mediate biodiversity. We grouped 27 variables into four variable sets: (1) ecological compensation (mainly semi-natural habitats), (2) in-field options (e.g. no growth regulator,... |
