| Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom. A total of 34 farms were analysed. The assessment was carried out using an attributional approach with system boundaries from cradle to farm gate. In relation to dairy production, a functional unit of 1 kg of energy corrected milk was used. The results gave an average of 1.32 kg CO2 equivalents per kilogramme of energy-corrected milk with standard deviation of 0.22, which is consistent with recent studies. The main contributor to this is enteric... |

| Mixed intercropping of spring barley (Hordeum vulgare L.) with field pea (Pisum sativum L.), faba bean (Vicia faba var. minor L.) or narrow-leafed lupin (Lupinus angustifolius L.) was compared to sole cropping in two field experiments at different locations, on a sandy loam soil and a sandy soil, in Denmark in 2001. Grain legumes were dominant in intercrops on the sandy loam soil, except for lupin, whereas barley was dominant in intercrops on the sandy soil site. Combined intercrop grain yields were comparable to grain yields of the respective sole cropped grain legume or sole cropped, fertilized barley on each soil site. On the sandy loam soil, pea-barley and faba bean-barley intercrops increased the proportion of plant N derived from N2 fixation in... |

| I dag udnytter flere og flere økologiske landmænd fordelene ved samdyrkning af bælgsæd og korn. Fordelene er mere stabile udbytter, mindre ukrudtstryk og lejesæd samt forbedret produktkvalitet for eksempel i form af mindre ærtesyge og højere proteinindhold i kornet. Der er dog stadig et væsentligst problem, nemlig at blandingspartier på nuværende tidspunkt ikke er en accepteret handelsvare. Det er problematisk, hvis ikke man selv har husdyr eller kan afsætte høsten direkte til en landmand, der kan fodre med blandingen. I dag er det oftest nødvendigt at lade korn- og foderstoffirmaet adskille blandingen mod betaling. Denne meromkostning er mange landmænd trætte af. Udbyttegevinsten, der opnås i blandingerne, forsvinder til disse ekstra omkostninger. |

| Growing global trade with organic products has increased the demand for environmental impact assessments during both production and transport. Environmental hotspots of organic soybeans produced in China and imported to Denmark were identified in a case study using a life cycle assessment approach. Furthermore, environmental impacts of organic and conventional soybeans at farm gate were compared in the case study. The total global warming potential (GWP) per ton organic soybeans imported to Denmark revealed that 51% came from transportation and 35% from the farm level. Comparing organic and conventional soybean at farm gate showed that GWP, non-renewable energy use, acidification and eutrophication was lower per ton organic soybeans, whereas land use was... |

| Including grass leys in organic arable rotations has potentially several benefits such as suppression of certain weeds, increased biodiversity (i.e. pollinators), increased soil carbon sequestration and productivity among others. The biomass from the grass mixtures can be refined into protein feed concentrate for monogastrics that can partly replace imported soybean, while the fibre fraction can be used as ruminant feed or for biogas. The grass mixtures can also be used directly for biogas. Increasing diversity of the mixtures will potentially also increase the yield stability and the benefits for biodiversity (pollinators), while the number of cuts per year will also have an effect. Thus, the use of multispecies mixtures in organic arable rotation for... |

| Increasing globalization affects agricultural production and trade and has consequences for the sustainability of both conventional and organic agriculture. During the last decades, agricultural production and yields have been increasing along with global fertilizer and pesticide consumption. This development has been especially pronounced in the industrialized countries and some developing countries such as China, where cereal yields have increased a remarkable twofold and 4.5-fold respectively since 1961. In those countries, food security has increased, a greater variety of food has been offered and diets have changed towards a greater share of meat and dairy products. However, this development has led to a growing disparity among agricultural... |

| During one intensive week in October 2005, the authors were gathered to discuss the impact that globalisation has on the Organic Food Systems and the opportunities that globalisation opens up for developing these systems. The meeting took place as a Ph.D. course under the auspices of the Research School of Organic Farming and Food Systems (SOAR; www.soar.dk). All participants research within Organic Agriculture and Food Production in one way or another. |

| Life Cycle Assessments (LCA) of food and agriculture generally include potential effects on global warming, eutrophication, ecotoxocity and acidification some of which again affect biodiversity. However, LCA most often does not include specific indicators of the product’s or agricultural system’s impact (negative or positive) on biodiversity. Using LCA methodology on agricultural products makes it highly relevant to assess the impacts of land use. Some LCA’s include a simple category of land use. This is sometimes interpreted as “nature occupation”. However, if this is the only impact category addressing land use related biodiversity, the LCA cannot distinguish between different forms of agricultural systems, which may differ in their biodiversity impact... |
