The main objective of this work was to analyse how increased harvesting for bioenergy production might affect other Ecosystem Services (ES) in two Norwegian municipalities (Ringsaker and Voss). The aim was to identify locations where synergies or conflicts between ES could be expected. The spatial distribution of eight different ES (3 provision, 3 regulation and 2 cultural services) was modelled using information provided by land use spatial databases and additional data sources. Model parameters were set by integrating existing research and expert knowledge. Maps showing the level of provision of ES were analysed using a moving window to analyse scale dependence in the spatial distribution of ES provision. Map algebra was then used to identify areas providing multiple ES, thus defining the most important areas on which to focus the management of both synergies and trade-offs. Finally, specific ‘binary bundles’ maps, where bioenergy provision was compared with each of the other ES, were developed. The methodology proved its utility to assess the compatibility of bioenergy uses with other services. This straightforward approach is readily replicable in other regions and can be used as a decision support tool for planning and designing provision areas, and to ensure sustainable forest management approaches.

Mountain areas in Norway provide important resources for livestock grazing. These resources are crucial for agricultural production in a country with limited agricultural land and a climate and topography that restrict production of feed and food. A key contributor in the harvest of these resources has been mountain summer farming and outfield grazing in general. However, the use of mountainous grazing resources has been declining strongly for several decades with the regrowth of formerly open areas as a consequence. In contrast, recreational use, number of holiday cabins and associated infrastructure is rapidly increasing. Conflicts between recreational and agriculture use have received increasing attention in different media. We investigated the spatial patterns of cabin development and key grazing areas in Norwegian mountain areas, analysing data on livestock, cabins, and associated infrastructure. We found a large number of cabins and associated infrastructure within high-quality grazing areas indicating that the quality of grazing has not been adequately considered in the location of new cabins. Taking into consideration that cabin development seems not to decrease, the reduced availability of grazing resources may result in an increasing level of conflict and also impact food security in the long run.

Abstract
Landscape ecology is repeatedly described as an applied science that can help reduce the negative effects of land-use and land-use changes on biodiversity. However, the extent to which landscape ecology is in fact contributing to planning and design processes is questioned. The aim of this paper is to investigate if and how landscape ecology can be integrated in a planning and design process, and to uncover possible problems that, e.g., landscape architects and planners, may face in such processes. Our conclusion, based on a case study from Asker municipality, Norway, is that such a landscape ecological approach has a lot to offer. However, it is difficult to exploit the potential fully for different reasons, e.g., biodiversity information tends to be specialized, and not easily used by planners and designers, and landscape ecological principles need an adaptation process to be applicable in a real-world situation. We conclude that for the situation to improve, landscape ecologists need to ease this process. In addition, we recommend collaboration across disciplinary boundaries, preferably with a common design concept as a foundation.
