Biografi

I hold a Ph.D. in ecology and I am generally interested in the factors that shape population and community dynamics. I have worked for many years in arctic and alpine areas where my focus has been herbivore-plant interactions in relation to climate change. Currently my work focus on how land use and land use change in the agricultural landscape affect biodiversity, population dynamics and community composition using birds and plants as indicators. Main responsibilities include management of and reporting from the Norwegian monitoring program for agricultural landscapes, with particular focus on the development and use of indicators of biodiversity.

Sommeren 2023 utlyste Vestfold og Telemark fylkeskommune, sammen daværende Viken fylkeskommune, en tilbudskonkurranse om å utarbeide en digital kartløsning som synliggjør naturlige økosystemtjenester. Kartløsningen er laget for kommunene Sandefjord, Larvik, Porsgrunn, Skien, Notodden, Nome, Ringerike, Aurskog-Høland, Rælingen og Moss. Hensikt med oppdraget er å se klimagassutslipp, klimatilpasning og naturmangfold i sammenheng for å styrke betydningen av grønnstruktur og økosystemer i arealbruksvurderinger. NIBIO har laget en rekke temakart som synliggjør økosystemtjenestene. Denne rapporten gjør rede for temakartene, datagrunnlaget og bruksmåter.

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.
