Contribution of organic farming to public goods in Denmark Organic Eprints
Jespersen, Lizzie Melby; Baggesen, Dorte Lau; Fog, Erik; Halsnæs, Kirsten; Hermansen, J.E.; Andreasen, Lise; Strandberg, Beate; Halberg, Niels.
The potential contribution of organic farming to the public goods, ‘Nature and Biodiversity’, ‘Environment’, ‘Energy and Climate’, ‘Human Health and Welfare’ and ‘Animal Health and Welfare’ in Denmark is guided and partly secured by the principles and specific requirements of the EU Organic Regulation. However, other factors, such as the production type, farm size, geographical location and—not the least—the management of the farm, also influence the contribution. Using the ban on synthetic pesticides and restricted use of antibiotics, including the requirements to compensate for and prevent such uses in organic farming, as examples, the positive and negative contributions of organic farming in relation to selected public goods were analysed. The...

Does organic farming enhance biodiversity? Complex issues and modelling approaches Organic Eprints
Andersen, Liselotte Wesley; Marchi, Chiara; Topping, C.J.; Strandberg, Beate; Bruus Pedersen, Marianne; Damgaard, Christian; Jensen, Thomas Secher; Olsen, Kent; Dalgaard, Tommy.
Changes in agriculture might drive changes in biodiversity and are expected to have just as serious an effect as climate change. These changes are results of complex changes in land-use as well as land management, intensification of management and structural developments in agriculture. In this review we present results of a recent research project (ICROFS 2013) focusing on organic farming and biodiversity in Denmark and relate the results to international studies that focus on drivers of biodiversity in the agricultural landscape. The project was organized under five major themes, forming the main sections of the present review paper: Impact on i) plant biodiversity ii) insect and food-webs in cereal fields, iii) small mammals, iv) natural genetic...

Effects on herbicides on hedgerow biodiversity Organic Eprints
Strandberg, Beate; Christensen, Kimmie K..
Low dosages of herbicides may reduce the number of flowers on non-target plants. Effect of herbicides on flowering and on pollen and nectar production are relevant end-points for effect assessment on non-target species. Herbicides have the potential to reduce the number of flowers in hedgerow vegetation and thereby also decrease the availability of pollen, nectar and seeds that are important food for many insects and birds. The biodiversity of hedgerow bottom vegetation is lower at conventional than at organic farms, presumably as a consequence of the herbicide use.

Herbicide impact on non-target plant reproduction: what are the toxicological and ecological implications? Organic Eprints
Boutin, Céline; Strandberg, Beate; Carpenter, David; Mathiassen, Solvejg Kopp; Thomas, P.J..
Declining plant diversity and abundance have been widely reported in agroecosystems of North America and Europe. Intensive use of herbicides within cropfields and the associated drift in adjacent habitats are partly responsible for this change. The objectives of this work were to quantify the phenological stages of non-target plants in in-situ field situations during herbicide spray and to compare plant susceptibility at different phenological stages. Results demonstrated that a large number of non-target plants had reached reproductive stages during herbicide spray events in woodlots and hedgerows, both in Canada and Denmark where vegetation varies considerably. In addition, delays in flowering and reduced seed production occurred widely on plants sprayed...

Økologisk jordbrug som refugier for biodiversitet (Refugia) Organic Eprints
Andersen, Liselotte Wesley; Marchi, Chiara; Strandberg, Beate; Bruus Pedersen, Marianne; Damgaard, Christian; Jensen, Thomas Secher; Olsen, Kent; Dalgaard, Tommy; Topping, C.J..
• Økologiske marker har mere ukrudtsbiomasse end konventionelle. • Der er flere blomstrende arter i økologiske hegn end konventionelle forudsat, at der er kontinuitet i den økologiske drift. • Der er flere små pattedyr i små økologiske biotoper end konventionelle. • Fjernmålinger fra fly eller satellit, kaldet remote sensing, kan skelne hvilken afgrødetype der dyrkes, samt forekomsten af småbiotoper. • Uanset driftformen er det vigtigt at inddrage naturhensyn i driften, dvs., at der findes ekstensivt drevne arealer (græsmarker, overdrev, enge) til natur og direkte afsatte arealer til natur.

Organic farming and biodiversity - the impact of organic farming on nature Organic Eprints
Andersen, Liselotte Wesley; Marchi, Chiara; Strandberg, Beate; Topping, C.J.; Jensen, Thomas Secher; Olsen, Kent; Bruus Pedersen, Marianne; Damgaard, Christian; Dalgaard, Tommy.
Organic farming is generally acknowledged for its positive effects on biodiversity and other landscape services. However, the intensity of farming has changed significantly through the last decade as ranks of traditional holistic organic farmers have been joined by much more economically-driven new organic farmers. At the same time there have also been steady improvements in farming methodology and crop types resulting in efficiency in organic farming which can often rival its conventional counterparts. Therefore, large variations occur between organic farms.

Time matters: Effects of duration of the organic management on biodiversity in hedgerows Organic Eprints
Strandberg, Beate; Damgaard, Christian.
Organic farming has been suggested to counteract declines in farmland biodiversity but comparisons to conventional farming have produced variable outcomes. At the plot and field scales positive effects of organic farming on abundance of birds, predatory insects, and soil organism have been found and for plants positive effects on species richness have been found in hedgerows. Establishment of new species is a slow process especially in nutrient rich habitats such as hedgerows in the farmland. Fluctuating market prices and short-term economic gains have become increasingly important as incentive for conversion from conventional to organic management and transition forth and back between practices has become more frequent. We investigated the effect of...

Time matters:effect of time since transition to organic farming on hedgerow ground vegetation Organic Eprints
Strandberg, Beate; Damgaard, Christian; Dalgaard, Tommy.
Agri-environment schemes such as organic farming has been implemented to counteract declines in farmland biodiversity but comparisons to conventional farming have produced variable outcomes depending on both taxa and landscape factors. However, changes in land-use may not always result in rapid changes in species distributions and diversity. The importance of such a time-lag between transition to organic farming and species responses have received little attention. We investigated the effect of time since transition from conventional to organic practice on the biodiversity of hedgerow ground vegetation in 30 hedgerows within two landscapes of different heterogeneity and land-use intensity. We found that time since transition of the neighbouring...
