CVBiografi
Jeg er utdannet naturforvalter (1990), og har en doktorgrad i landskapsøkologi fra NMBU (1997). Som landskapsøkolog er jeg spesielt opptatt av landskapets innhold og romlige struktur; hvordan landskapet fungerer som en mosaikk der ulike arealtyper og landskapselementer er geografisk fordelt, hvilken kvalitet de har og hvordan de endres over tid.
Jeg har jobbet i mange år med tilstand og endring i jordbrukslandskapet, med spesiell fokus på hvordan endringer i landskapets utforming kan ha betydning, for eksempel for biologisk mangfold og hvordan vi opplever landskapet. Dette inkluderer blant annet utvikling og drift av overvåkingsprogrammet for jordbrukets kulturlandskap, det såkalte 3Q-programmet, og indikatorer som kan brukes til å overvåke endringer.
Jeg kan dessuten litt om humler, litt om romlige analyser og GIS, er opptatt av jordvern og jordbruk, samt arealplanlegging. Jeg er medlem av Executive Commitee i IALE-Europe.
Jeg er professor II ved NMBU, der jeg underviser i landskapsøkologi (LAA370) og av og til veileder studenter med bachelor- eller masteroppgaver.

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.

The value of genetic resources in agriculture is hard to overestimate as they are decisive for food safety, provide options for adaptation of future diet needs, and underpin a vast amount of biodiversity. To enable an effective conservation of these resources, we need knowledge about where they are located. The EU project GenRes Bridge showed that this knowledge is indeed modest at the European level. A source of genetic resources with particular potential for use in agriculture, e.g. related to the future adaptation to climate change, are crop wild relatives (CWR). Crop wild relatives are plant species categorized as wild relatives of cultivated plants and are used here as an indicator of genetic resources in the landscape. We therefore wanted to explore new ways of identifying hotspots of genetic resources, highlighting the landscape as a starting point. It is well established that landscape heterogeneity is closely related to biodiversity, although to our knowledge studies hitherto have rarely looked at the relation between landscape and genetic resources. Focusing on crop wild relatives, used here as an indicator for genetic resources in the landscape, we wanted to assess whether we could identify how landscape variation in topography and land cover has consequences for the spatial distribution of genetic resources that may be important in the future development of agriculture. Here we report the results from this pilot study where we have tested whether there is a correlation between landscape heterogeneity and agricultural genetic resources, using 5 x 5 km grid cells as spatial units. We used the presence of the crop wild relatives (CWR) which are prioritized for conservation in Norway as indicators of agricultural genetic resource diversity and extracted landscape heterogeneity descriptors from publicly available sources. The results from our study do suggest that landscape diversity could be a path worth following in searching for these resources in the landscape, and thus also important in decision-making on planning and management in these diverse landscapes.

The study focuses on ecosystem services, historical aspects, and natural diversity. Specifically, it assesses possible proxies for investigating a set of cultural ecosystem services from the Norwegian agricultural landscape. Agricultural areas on the Norwegian land cover map surrounded by a 100 m wide buffer zone were analyzed for recorded historical buildings, cultural heritage sites, red-listed vascular plant species (defined as being at varying degrees at risk of extinction), and red-listed nature types (defined as endangered or vulnerable). The results indicate significant contributions from agricultural landscapes with respect to historical buildings, cultural heritage sites, and red-listed plant species. Regarding red-listed nature types, the contributions were diverse. The ecosystem proxies investigated showed increasing distribution trends with increasing proportions of agricultural landscapes in the spatial units, with a sharp increase with smaller area sizes. However, for cultural heritage sites the trend was different when the proportion of the agricultural landscape was below 25%; it showed a very slow increase. In conclusion, the study highlights the agricultural landscape’s diverse contributions to the investigated ecosystem services in Norway, prompting the need for further research on additional ecosystem services to ensure the continued delivery of environmental and social well-being.

Det stilles mange og store og inngripende krav til dagens bonde, og det er mange ulike målsetninger å forholde seg til. Dette skaper fort usikkerhet, spesielt når bonden møter målkonflikter. For eksempel skal det produseres mer og mer effektivt samtidig som det blant annet skal tas en rekke miljøhensyn. Undersøkelser viser imidlertid at det er mulig å øke avlingene, nettofortjenesten og redusere klimagassutslipp.

Integrering av klima, miljø og folkehelse i det norske matsystemet for å vurdere effektive, trygge og akseptable politiske alternativer
Norges matsystem utfordres ikke bare av interne målkonflikter, men også av økende ambisjoner knyttet til landbruk og mat fra andre politikkområder. Utslipp av klimagasser fra landbruket må reduseres, tap av natur og biologisk mangfold må stanses, og nye kostholdsanbefalinger forventes å flytte kostholdet mot mindre kjøttforbruk og -produksjon.
