| Pluriactivity in organic farming in Denmark, and its implications for intensity of farming- and nature practises. Societal demands to the farming sector are changing, from solely focussing on foodproduction to an increased interest in the production of environmental and nature values, as well as a socio-economically sustainable countryside. Coincident with this development agricultural restructuring takes place with high speed, implying structural development: fewer and larger farms. Meanwhile some farming households seek alternative pathways, including diversification of activities and use of resources. These pathways sometimes express alternative development choices other than farm intensification. A crucial question is thus, if some of these... |

| With changing societal goals for the rural areas, the question what role organic farming may play in rural development arises. Based on interviews with 10% of Danish organic farms, we explore which types of organic farms exist in terms of resources used for agricultural activity, what role do other types of income activities play and how are the different strategies co-existing or complementing eachother. Based on resource use on organic farms by farmer and spouse, less than half of the farms can be characterzed as full-time farms, with part-time farms making up one third and hobby farms 17%. More than half of the organic farms are managed by a farmer with the main income from off-farm work, and half of the farms engage in Other Farm-based Activities... |

| This study explores the localisation of organic farms in Denmark for the three years 1994, 1997 and 2001, on a county and parish level. Spatial concentration is found in counties with a high share of milk producers, but also in the counties, which contain the two largest urban centres. General regional specialisation of the agricultural sector in Denmark contributes to the explanation of concentration patterns of organic conversion, but other factors like a regional favourable policy climate and -support also appear to play a role. Major variations in concentration within regions are found, suggesting that local factors play an important role for the explanation of spatial patterns of organic conversion. |

| ”Naturkvalitet i Økologisk Jordbrug”er et forskningsprojekt knyttet til Forskningscenter for Økologisk Jordbrug. Formålet med projektet har været at udvikle nye metoder til at karakterisere naturindholdet på de økologiske bedrifter, at undersøge forvaltningen af natur på forskellige bedrifter, og at diskutere udviklingsmuligheder og måder at formidle denne viden på mellem interessegrupper. Denne rapport er en præsentation af de resultater, der kom ud af en omfattende interviewundersøgelse som 347 danske økologiske landmænd deltog i, i 2002-03. |

| The objective of this study was to evaluate the differences in the energy consumption between the production of certified organic pear, green food certified pear, and conventional pear in two areas in China. Data were collected from interviews with farmers during 2007 and 2008. Energy inputs were significantly higher in organic systems compared with conventional and green systems. Fertilizer was the most important contributor to energy consumption in all three farming systems. Three calculation methods for energy value of manure have been found in the literature: substitution method, by-product method, and thermal method. The choise of various calculation methods for estimating the energy value of manure turns out to have great influence on the results in... |

| Ni frøavlere og lige så mange frugtavlere har i løbet af sommeren vandret deres bedrifter tynde for at registrere blomster og kortlægge redepladser for de vilde bier. Deres registreringer skal bruges til at udvikle et nyt redskab, der kan bruges til at skabe bedre leveforhold for bierne. Der er almindelig enighed om, at de vilde bier har det svært i det intensivt dyrkede danske landbrugslandskab. Selv på økologiske bedrifter, hvor de ikke er udsat for pesticider, kan de mangle føde- og redesteder, og kun den enkelte landmand eller frugtavler kan ændre på situationen. Derfor har vi i forskningsprojektet BEEFARM sat os for at udvikle et værktøj, som landmanden kan bruge til at vurdere leveforholdene for vilde bier på bedriften. Ni økologiske... |

| This report is the result of a network project which was established to discuss the potential for collaboration on development of systemic approaches to pest management without pesticides between Chinese and Danish researchers. The focus is on systemic approaches rather than input substitution of synthetic chemicals with agents of natural origin, however, the latter is considered as an integrated tool for the development and design of systemic approaches. The discussions were, furthermore, limited to management of invertebrate pests as well as diseases, while other pests such as weeds have not been included in the discussions. The discussions took place at two workshops and were based on presentations of research from the two countries and field visits in... |

| Density and management of landscape elements on organic farms were investigated for 345 organic farms in Denmark in 2001, representing approximately 10% of the total number of organic farms. The density of hedgerows, area habitats and ponds was estimated and related to various aspects of farm character, such as size, type and lifestyle/part time/full time farms, as well as region and biophysical context. A large variation in the densities was found, the highest densities were found on the smallest farms. Farm size was the farm parameter that was closest related to the density of landscape elements as well as landscape structural variables. Farm size was related to the other farm characteristics. |

| I det seneste tiår har økologisk landbrug fået en stærkt øget udbredelse. Hvor der i begyndelsen af 1990'erne kun var få tusinde ha, som blev drevet økologisk, er der i 2001 over 170.000 ha, svarende til ca. 6,5 procent af det samlede danske landbrugsareal. Den samfundsmæssige interesse i økologisk landbrug er i høj grad drevet af de positive virkninger på natur og miljø, som det økologiske landbrug formodes at have. Samtidig har de samfundsøkonomiske effekter ved en øget udbredelse af økologisk landbrug været diskuteret. Bl.a. på denne baggrund blev der i regi af Forskningscenter for Økologisk Jordbrug iværksat et forskningsprojekt om Samfunds- og miljømæssige konsekvenser af forskellige strategier for udvikling og udbredelse af økologiske... |

| An analysis of peer reviews of 84 organic farming grant applications, submitted to The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS) in 2001 was carried out to investigate whether peer reviews were influenced by the peer reviewers’ affiliation to organic agriculture research and to what degree peer reviewers distinguish between scientific quality and societal relevance. Fifteen reviewers were grouped in three groups (1) scientists with affiliation to organic farming research, (2) scientists without affiliation to organic farming research and (3) users of the research. The scientist groups assessed societal relevance of the grant applications and scientific quality as a sum of three scientific criteria and the... |

| Conversion to organic farming shows a large variation at the county level in Denmark. This is attributed to proximity to urban markets and values, regional specialization of farm types and municipal promotion of organic farming. However, also at the local level there is a substantial variation in the localization of organic farms. This may be related to negative influences of social barriers and positive influences of fiery souls among producers and advisors. |

| Omlægning til økologisk jordbrug er ujævnt fordelt mellem landets amter. Dette hænger sammen med faktorer som bynærhed, bedriftstyper og den regionale indsats, der er gjort for økologien. Men også på lokalt niveau er der en ujævn fordeling af de økologiske bedrifter. Det kan fx skyldes en negativ betydning af sociale barrierer for omlægning, men også en positiv betydning af ildsjæle blandt såvel producenter som rådgivere. |
