Biography

I am part of the coordinating team for Norway's national greenhouse gas inventory for the Land Use, Land-Use Changes, and Forestry (LULUCF) sector under the UNFCCC and EU. My work includes calculating and reporting carbon emissions and removals for the LULUCF sector and contributing to projects that analyze the coherence and effects of national and international policies on land use, including drivers, correlations, and outcomes. I have experience in risk and uncertainty analysis, long-term planning in the forest sector, and evaluating payment for ecosystem services schemes. My expertise includes LULUCF, climate change, carbon accounting, policy analysis, and risk and uncertainty analysis.

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.

Abstract

Key messages: Multifunctionality should serve as a guiding principle for forest governance and investment, complementing production and conservation objectives. To operationalise this vision, three guiding principles should inform EU and national policies: • Plan and manage at the landscape level balancing production, biodiversity, climate adaptation and social needs in complementary ways. Policies should support a diversity of management practices. • Align sectoral policies to ensure coherence between forestry, energy, biodiversity, climate and social objectives. • Reward and support multifunctionality explicitly through advisory programmes, certification systems, and financial mechanisms that recognise and support diverse management practices.
