Researcher at the Department of Forest and Climate.
Working on Land Use, Land-Use Changes, and Forestry (LULUCF) related to greenhouse gas emissions. My area of focus is related to the analysis and estimation of emissions and uptake from LULUCF carbon stocks, development of projections of land development, and associated emissions and uptake under different scenarios, and LULUCF guidelines and regulations related to national reporting and accounting (IPCC, UN and EU). I coordinate the national greenhouse gas inventory for the LULUCF sector under the UN Climate Convention and the EU.
Area of expertise: LULUCF, climate change, biogeochemistry/environmental chemistry (processes and cycles in soil and water), analytical chemistry, modelling, and programming in R.
Abstract
There is an increasing interest in using forests as a natural solution for enhancing terrestrial carbon dioxide removal, as part of climate smart forestry strategy to have a significant role in climate mitigation efforts. Harvest deferral is seen as one carbon farming practice to increase carbon sequestration in forests. The aim of this study was to evaluate the role of harvest deferral on carbon forest sink potential of Norwegian forests in the short, medium and long-term. Here, we carried out scenario analysis for the whole Norway during the 21st century to assess the effect on carbon sequestration of delaying harvest in a certain number of forests. The scenarios represented different levels of harvest deferral through Norwegian forests. Delaying harvest would increase CO2 removals in the medium (2050) and long-term (2100), resulting in an additional uptake of approximately 6 and 34 Tg CO2, respectively, when extending rotation for 20 years in those plots with high growth increment in the last 5 years. Scenarios where harvest was delayed for a longer period showed slightly higher CO2 removals by the end of the century. While harvest deferral scenarios showed positive effects in terms of climate change mitigation potential, there are several other aspects that need to be considered, such as trade-offs and synergies with other sustainability goals, leakage, market behaviour and willingness of forest owners to get involved in these carbon farming practices.

NIBIO har utviklet en karttjeneste for å beregne utslipp og opptak av klimagasser for nåværende og planlagt arealbruk. Kartgrunnlaget, som beskriver nåværende arealbruk, benytter offentlige datakilder. Brukere av kalkulatoren kan laste inn arealplaner eller tegne inn arealer og klassifisere dem med arealformål. Beregningene i kalkulatoren skjer i tråd med retningslinjene i det nasjonale og kommunale klimagassregnskapet for skog- og arealbrukssektoren (LULUCF) og anbefalinger i Miljødirektoratets Håndbok for konsekvensutredninger. Kalkulatoren forenkler arbeidet med å vurdere klimakonsekvenser ved arealbruk og arealbruksendringer i kommunal planlegging.

Grøfter i skog har blitt etablert for å bedre vekstforholdene på dårlig drenerte arealer. I dag er nygrøfting av myr og sumpskog for skogproduksjon forbudt, men vedlikehold av eksisterende grøfter – såkalt grøfterensk – er fortsatt aktuelt på produktiv skogsmark. Tiltaket er omdiskutert, særlig på grunn av mulige klimagassutslipp. Så hva betyr egentlig grøfterensk for klimaet?

EU Climate Policy Implications for Land Use in Norway: Managing Trade-offs and Achieving Policy Coherence (ClimaLand)
The ClimaLand project will investigate trade-offs between policy goals, governance levels, and sector interests, and seek to identify how to design more coherent climate and land-use policies. An important objective is to investigate how conflicting policy goals can be handled and various considerations and land-use interests balanced.

Optimizing Carbon, Soil Health and Yield in Coffee-Forest Systems as a Climate-Smart Land Management in Ethiopia (CoffeeLand)
CoffeeLand is an interdisciplinary research project aimed at advancing climate-smart land management in Ethiopia’s coffee-forest systems, which are critical for biodiversity, livelihoods, and global Arabica coffee genetic resources. These systems support millions of smallholder farmers but are increasingly threatened by climate change, land-use pressure, and declining productivity.
