The level of support to Norwegian agriculture is partly justified with reference to agriculture’s multifunctionality. The concept of multifunctionality involves the provision of so-called “public goods» by agriculture, in addition to the production of food and fibre. Examples of these public goods include cultural landscape, biodiversity, ecological functions, cultural heritage, the viability of rural areas, and food security. The overall aim of the research project “Operationalization of multifunctionality using the CAPRI modeling system» is to study the effects of policy instruments on agriculture’s multifunctionality by defining quantitative indicators for selected elements of agriculture’s multifunctionality that can be implemented in the agricultural sector model CAPRI. This working paper takes a first step towards the appropriate regionalization when multifunctionality is concerned. The current regionalization of the CAPRI model is at the county level. This approach fails when multifunctionality is concerned, because many issues of multifunctionaliy (e.g., cultural landscape aspects) are independent of administrative borders at that level. As the aim of the overall project is to study the effects of policy instruments on agriculture’s multifunctionality, it is important to design regions within the CAPRI model that to a greater extent exhibit similar characteristics with respect to aspects of agriculture’s multifunctionality. Accordingly, it is reasonable to assume that policy changes will have quite similar effects on the multifunctionality indicators within each of these CAPRI regions. This task has been addressed by performing a cluster analysis by which Norwegian municipalities have been grouped with respect to their performance on variables that are expected to describe different aspects of the multifunctionality of agriculture. This information will then later on be used to regionalize the CAPRI model accordingly. […]

I 1998-2000 ble det biologiske mangfoldet av minerfluer undersøkt i konvensjonelt og økologisk dyrket korn og gras i Sørøst-Norge. Fluene ble fanget med håv i 1x10m store ruter i åkerkanten, 0,5, 5, 15 og 30 m ute i åkeren. Totalt 5822 individer av minst 66 arter ble fanget. Deler av biodiversiteten var høyere i de økologiske feltene. I både konvensjonelle og økologiske felt ble biodiversiteten redusert når en gikk fra åkerkanten og utover i åkeren. In 1998-2000 the species richness and species diversity of Agromyzidae were investigated in conventionally and biologically managed cereal and grass fields in Southeastern Norway.Flies were caught with sweep-net in 1x10 m plots in the boundary, 0.5, 5, 15 and 30 m into the fields. A total of 5822 specimens of at least 66 species were caught. Parts of the biodiversity was shown to be higher in biological fields. In bothconventional and biological fields the biodiversity was reduced when moving from the boundary and into the field.
