| Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to which farm management schemes affect biodiversity components other than species richness, and whether impacts differ across spatial scales and landscape contexts. Using a global metadataset, we quantified the effects of organic farming and plant diversification on abundance, local diversity (communities within fields), and regional diversity (communities across... |

| Par rapport à l'agriculture conventionnelle, l'agriculture biologique fournit sensiblement plus de prestations en faveur de la biodiversité. Selon l'altitude à laquelle elles se trouvent, les exploitations biologiques comptent entre 46 et 72 pour cent de surfaces proches de l'état naturel en plus, abritent 30 pour cent d'espèces en plus et 50 pour cent d'individus en plus que les exploitations non-biologiques. Grâce à la faible intensité d'exploitation et la proportion plus élevée de surfaces proches de l'état naturel, on rencontre encore beaucoup d'espèces végétales et animales régionales typiques sur les exploitations biologiques. Les agriculteurs peuvent ainsi profiter d'un écosystème intact et fonctionnant de manière durable. |

| Amara ovata und A. similata, zwei im Adultstadium phytophage Laufkäferarten, wiesen in Rapskulturen im Vergleich zu Winterweizenflächen und ökologischen Ausgleichsflächen (Buntbrache und extensiven Wieslandstreifen) in der Nähe von Basel ein mit TRichterfallen gemessene, hohe Aktivitätsdichte auf. Handfänge und Beobachtungen auf fünf anderen Rapsfeldern in der Umgebung von Basel zeigten, dass Amara ovata und A. similata Schoten, Samen und Blüten der Rapskultur fressen. Aufgrund der nahen Verwandtschaft des Rapses mit anderen Brassicaceen nehmen wir an, dass Raps für A. ovata und A. similata eine bevorzugte Nahrungsquelle darstellt. Ob dadurch ein wirtschaftlicher Schaden entsteht, ist zurzeit noch nicht klar. Ein stärkerer Befall ist in der Nähe von... |

| 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... |

| Determining explanatory environmental factors that lead to patterns of biodiversity in cultivated landscapes is an important step for the assessment of the impact of landscape changes. In the context of an assessment of the effect of agricultural national extensification programme on biodiversity, field data of 2 regions were collected according to a stratified sampling method. A distribution model of 3 indicator species taxa (butterflies, spiders, and carabid beetles) is related to influencing factors by means of multivariate statistics (CCA, partial CCA). Hypothetical influencing factors are categorised as follows: (1) habitat (habitat type, management techniques) and (2) landscape (habitat heterogeneity, variability, diversity, proportion of natural and... |

| Carabid populations (species diversity and abundance) in different crops were investigated during the period from April to July 1993 to 1995. The study was carried out on two farms in North-Western Switzerland. Nine fields with winter cereals (4x wheat, 2x spelt, 2x barley, lx rye), three rape fields, five spring cultures (3x maize, lx soybeans, lx potatoes) and an arable meadow were studied. In winter cereals, more carabid species were found than in spring cultures. In barley, we recorded fewer carabid species and individuals, larger numbers of hygrophilaus carabids and a more even population structure than in the other cereals. In rape, we recorded the highest numbers of carabid species and individuals, and very large numbers of Amara similata and A... |

| Fazit Unter Einbezug der Erkenntnisse von Betriebspaarvergleichen und Parzellenexaktversuchen (Langzeit DOK-Versuch) kommen wir zur Schlussfolgerung, dass biologischer Anbau kombiniert mit qualitativ wertvollen naturnahen Flächen eine Schlüsselrolle für eine nachhaltige Förderung der Nutzarthropodenfauna in der ackerbaulich geprägten Kulturlandschaft darstellt. Regional ausgelegte Agrarumweltprogramme müssten so ausgerichtet sein, dass nicht nur ‚punktuell’ auf Betriebsebene sondern vermehrt auf der Landschaftsebene unter Berücksichtigung der Anbauintensitäten die Kulturlandschaft spezifisch aufgewertet wird. Dies würde zur Verbesserung verschiedener Umweltfunktionen (z.B. Biodiversität, natürliche Schädlingsregulation) wesentlich beitragen. |

| Im Projekt „Mit Vielfalt punkten – Bauern beleben die Natur“ erforschten und erprobten das FiBL und die Vogelwarte Sempach seit 2009 Massnahmen und Instrumente, um die Biodiversität auf Landwirtschaftsbetrieben wirksam zu fördern. Es hat sich gezeigt, dass die Produktion von Nahrungsmitteln sehr wohl mit der Erhaltung und Förderung der Biodiversität vereinbar ist, ja sogar ökonomische Vorteile bringen kann. An der Schlussveranstaltung vom 30. Juni 2017 wurden die wichtigsten Resultate einem breiteren Publikum vorgestellt und deren Stellenwert für die Weiterentwicklung nachhaltiger Produktions- und Ernährungssysteme mit Akteuren aus Verwaltung, Politik und Markt beleuchtet und diskutiert. |

| 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... |

| Over the last century, the intensification of agriculture with high inputs of synthetic pesticides and fertilisers combined with monocrop specialisation has been detrimental to the diversity of genetic resources of crop varieties and livestock breeds, to the wild flora and fauna species and to the diversity of ecosystems. Higher levels of biodiversity can strengthen farming systems and its resilience under changing environmental conditions. This chapter gives an overview of the impact of organic farming on biodiversity. The chapter considers land-use intensity, the impact of organic farming on biodiversity, biodiversity at different spatial scales and the impact of organic farming on selected functional groups. Finally, the chapter discusses some examples... |

| Farmland biodiversity has often been assessed, but seldom at the farm scale, although it is ultimately the farm level at which decisions are taken. Therefore, a credit point system (CPS) was developed based on 32 options known to enhance farmland biodiversity. It was verified whether the resulting CPS score and farm-scale biodiversity are correlated considering four indicator groups (plants, grasshoppers, butterflies and birds) on 133 farms in the Swiss lowland. We further compared the suitability of the CPS score in reflecting farm-scale biodiversity to three alternative habitat measures, i.e. the amount of ecological compensation areas (ECAs, i.e. agri-environment scheme options), ECAs with a high ecological quality and valuable semi-natural elements... |
