I perioden 2003 – 2013 har gras- og beitearealet i Møre og Romsdal blitt redusert med om lag 10 %. Samtidig er det en politisk målsetting at husdyrproduksjonen så langt som mulig skal skje på grunnlag av norsk grovfôrareal, beitebruk og norske fôrråvarer. Skal vi lykkes med det krever det at vi bruker jord- og beiteressursene våre langt bedre enn i dag.

Purpose Outside farming, pluriactivity is generally considered as undesirable, whereas agricultural economists tend to recommend part-time farming. This contradiction is to be solved. The paper aims to discuss this issue. Design/methodology/approach Linking tax-payer and statistical farm-level data from Norway, the authors tested how profitable part-time farming is for Norwegian farm households. Findings The analysis showed that concentrating on either working on-farm or off-farm generates a higher household income than combining the two. Practical implications Part-time farming may be a lifestyle decision, but apparently is not economically optimal for most farms. Originality/value The contribution solves an apparent contradiction between the discourses inside and outside agriculture.

Despite global deforestation some regions, such as Europe, are currently experiencing rapid reforestation. Some of this is unintended woodland encroachment onto farmland as a result of reduced livestock pasture management. Our aim was to determine the likely impacts of this on exposure to ticks and tickborne disease risk for sheep in Norway, a country experiencing ecosystem changes through rapid woodland encroachment as well as increases in abundance and distribution of Ixodes ricinus ticks and tick-borne disease incidence. We conducted surveys of I. ricinus ticks on ground vegetation using cloth lure transects and counts of ticks biting lambs on spring pastures, where lambs are exposed to infection with Anaplasma phagocytophilum, the causative agent of tick-borne fever in livestock. Pastures had higher densities of I. ricinus ticks on the ground vegetation and more ticks biting lambs if there was more tree cover in or adjacent to pastures. Importantly, there was a close correlation between questing tick density on pastures and counts of ticks biting lambs on the same pasture, indicating that cloth lure transects are a good proxy of risk to livestock of tick exposure and tick-borne disease. These findings can inform policy on environmental tick control measures such as habitat management, choice of livestock grazing area and off-host application of tick control agents.
