A landscape region can be drawn on a map as a geographic feature with distinct boundaries. Reality is, however, that the change from one landscape to another usually is gradual and that landscapes therefore have uncertain or undetermined boundaries. A thematic map of landscape regions is therefore a too simple model of the landscape. An alternative approach is to consider landscape categories as purely theoretical concepts. With this perspective, a particular geographical location can be more or less affiliated with a number of different landscape categories. Such a conception of landscape does not lead to a traditional thematic map of uniform, non-overlapping regions, but to a landscape model composed of multiple overlapping probability surfaces. This article shows how such a landscape model can be established using binary logistic regression. The method is tested and the result is assessed against an existing landscape map of Norway much used in policy impact analysis in this country. The overall objective is to develop a data driven landscape model that can supplement, elucidate and for some purposes maybe even replace, the qualitative landscape description represented by the traditional landscape map.

As a primary industry, agriculture is directly dependent on natural conditions and therefore potentially vulnerable to the consequences of climate change. In Norway and Northern Norway in particular, the future climatic changes are expected to be overall positive. Still, the consequences for agriculture are not straightforward, but dependent on the interaction between different weather and biological elements, as well as political, economic and social conditions. In this interdisciplinary study we have assessed biological and agronomic effects of climate change, and their interaction with political, economic and social factors, to identify farmers' vulnerability and adaptive capacity to climate change. The assessments are based on downscaled climate change scenarios and interviews with local farmers in the three northernmost counties in Northern Norway (latitude 65.5° to 70°). The study shows that the farmers to a degree are vulnerable to a changing climate, not mainly because of the direct effects of changing growing conditions, but because these changes are an added factor to an already tenuous situation created by Norwegian agricultural policy and socio-economic development in general. We have found that farmers are highly adaptive, to both changing growing conditions and changing agricultural policies. However, changes in policy are currently a greater challenge to farmers than climate change, and such changes are therefore a more salient driver of vulnerability.

Abstract
A combined wood impregnation process including impregnation with a chromium-free wood preservative and oil treatment was evaluated with regard to leaching of copper during the oil process. Two different experimental setups make up the balance of copper content in oil, wood samples and condensate water, also taking different fixation times and process durations into account. Copper is sufficiently fixed after 24 hours, and leaching of copper into the oil is low. Increasing the oil process time does not lead to increased leaching. The hot oil treatment of impregnated wood under vacuum atmosphere is a fast drying method without major negative consequences for the impregnated copper.
