This article uses an activity-based understanding of landscape to explore values related to perceived land cover diversity. Perceptions within two user groups, members of landowner families and hiking tourists in a mountain area in western Norway, were related to a simultaneous land cover survey, and compared to experts' evaluations of land cover and to the aims of landscape protection in the area. Users perceived the area as being significantly more diverse and valuable than experts did, which stresses the importance of taking user perception into account in landscape protection and management. Some central landscape values were dependent upon land use outside the boundaries of the protected area. This illustrates that measures within structurally defined land units are not necessarily sufficient for maintenance of landscape values experienced by users. Land use in both respects, as an upholder of values and as a way of experiencing or perceiving them, should receive an increased role in the determination of management units.

Norwegian agriculture has, as in most western-European countries, gone through several periods of change during the last 100 years. Pronounced changes have occurred in production systems and the spatial organisation of farm land, as well as agricultural policy. During the last 50 years, official statistics document a marked decline in the number of active farms. This decline has caused concern, as Norway traditionally has had an agricultural policy that emphasises self-sufficiency and rural settlement. Yet statistics also show that the amount of agricultural land in use has remained the same. This is usually explained through a larger proportion of tenanted land, as technological progress has allowed production levels to be maintained with a smaller workforce. Studies elsewhere in Europe show, however, that tenancy may not promote the same levels of investment and landscape management as owner occupation. To assess the potential impact of this change on Norway's landscape (and its value as both a cultural and tourism resource) we analyse tenancy patterns in Norwegian agriculture between 1999 and 2003. In particular we note that, even if owner occupation remains strong nationally, when the statistics are broken down by municipality, tenancy has increased significantly in some areas. This has left large areas of land managed as tenancies by a relatively small number of farmers, including parts of the iconic west coast fjords. We conclude therefore that further work is urgently required to establish whether the effects of tenancy seen elsewhere apply to Norway, whether this exposes key landscapes to increased risk of abandonment and if so what appropriate political responses there could be.

Jordbruksarealene er viktige med tanke på lagring av karbon. Kombinasjon av jordtype og arealbruk er avgjørende for hvor mye karbon som kan lagres. For å ivareta karbon i jordbruksjord er det nødvending at rett tiltak skjer på rett sted.

CORINE Land Cover (CLC) is a seamless European land cover vector database. The Norwegian CLC for the reference year 2006 (CLC2006) was completed by the Norwegian Forest and Landscape Institute (Skog og landskap) in 2009 and was produced according to CLC2006 technical guidelines (EEA 2007). CLC has a common nomenclature with 44 classes that is used throughout Europe. 31 of these classes are found in the Norwegian dataset. A coordinating Technical Team from the European Topic Centre on Land Use and Spatial Information (ETC-LUSI) is coordinating the mapping efforts ensuring that the classification is applied in a similar fashion in each country....

All the Norwegian CLC2006 classes are documented through descriptive statistical “profiles” of the actual contents in each class. The CLC2006 profiles are worked through based on an overlay operation between CLC2006 and AR5 (under the timberline) and AR50 (above the timberline). Based on this dataset statistics are generated, that shows the percent distribution of AR5 and AR50 classes in each CLC2006 class. The study was carried out with funding from the Norwegian Space Centre.

The coastal heath region along the western coast of Norway, dominated by Calluna vulgaris, is undergoing rapid change. Vegetation changes are caused by changes in management, including reduced frequency or abandonment of periodic heath burning and reduced cutting and grazing. The islands of Froan, in the outermost part of Sør-Trøndelag County in mid-western Norway, are dominated by coastal heath in a state of recession due to reduced traditional land use. The coastal heath is acknowledged as vulnerable and valuable by national environmental authorities, and local landscape management is supported by different national subsidies. The authors mapped the vegetation on Froan and used rule-based GIS-modelling to predict the relative potential for future vegetation changes. The model was based on a range of map layers, including management themes such as history of heath burning and peat removal, current practices of sheep grazing, and also themes derived from the vegetation map, such as soil nutrients, soil moisture and present management status. The resulting model output provides relative probabilities of future changes under different land-use scenarios, and highlights where management efforts should be focused in order to maintain the traditional landscape character.
