Climate change mitigation potential of biochar from forestry residues under boreal condition
(Peer reviewed; Journal article, 2021-10-18)Forest harvest residue is a low-competitive biomass feedstock that is usually left to decay on site after forestry operations. Its removal and pyrolytic conversion to biochar is seen as an opportunity to reduce terrestrial ... -
CO2-equivalence metrics for surface albedo change based on the radiative forcing concept: a critical review
(Journal article, 2021-07-01)Management of Earth’s surface albedo is increasingly viewed as an important climate change mitigation strategy both on (Seneviratne et al., 2018) and off (Field et al., 2018; Kravitz et al., 2018) the land. Assessing the ... -
Anaerobic digestion affecting nitrous oxide and methane emissions from the composting process
(Peer reviewed; Journal article, 2021-07-02)Composting and anaerobic digestion are the most common ways to treat organic residues. Sometimes the organic rest after anaerobic digestion is also composted. In this study we investigated greenhouse gas emissions from ... -
Improving living biomass c-stock loss estimates by combining optical satellite, airborne laser scanning, and nfi data

Biotic threats for 23 major non-native tree species in Europe
(Peer reviewed; Journal article, 2021-08-06)For non-native tree species with an origin outside of Europe a detailed compilation of enemy species including the severity of their attack is lacking up to now. We collected information on native and non-native species ... -
The Gaupne area in Sogn og Fjordane – a hot-spot for lichens in Norway
(Peer reviewed; Journal article, 2021)During a three-day field trip to the Gaupne area, Luster kommune, three main localities were visited in search of lichens. A total of 35 lichens or lichenicolous fungi were found to be new to Sogn og Fjordane, most of which ... -
A review of Sensors, Sensor-Platforms and Methods Used in 3D Modelling of Soil Displacement after Timber Harvesting
(Peer reviewed; Journal article, 2021)Proximal sensing technologies are becoming widely used across a range of applications in environmental sciences. One of these applications is in the measurement of the ground surface in describing soil displacement impacts ... -
Direct and indirect impacts of climate change on wheat yield in the Indo-Gangetic plain in India
(Peer reviewed; Journal article, 2021-02-28)The Indo-Gangetic Plain (IGP) is one of the main wheat-production regions in India and the world. With climate change, wheat yields in this region will be affected through changes in temperature and precipitation and ... -
Recent strengthening of snow and ice albedo feedback driven by Antarctic sea-ice loss
(Peer reviewed; Journal article, 2021-10-28)The decline of the Arctic cryosphere during recent decades has lowered the region’s surface albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the Antarctic cryosphere plays ... -

Taksering av elgbeite, Stjørdal – grunntakst 2021
(NIBIO-rapport;7(172) 2021, Research report, 2021-11)NIBIO har på oppdrag av Stjørdal kommune utført taksering av elgbeite i de skogkledde delene av kommunen i juli 2021, for å kunne si noe om beitetilbud og beitepress. Vi fant at den totale tettheten av beite-trær i elgens ... -
Constraining the HBV model for robust water balance assessments in a cold climate
(Peer reviewed; Journal article, 2021-01-19)Robust projections of changes in the hydrological cycle in a non-stationary climate rely on trustworthy estimates of the water balance elements. Additional drivers than precipitation and temperature, namely wind, radiation, ... -
Prediction and model-assisted estimation of diameter distributions using Norwegian national forest inventory and airborne laser scanning data
(Peer reviewed; Journal article, 2021-04-07)Diameter at breast height (DBH) distributions offer valuable information for operational and strategic forest management decisions. We predicted DBH distributions using Norwegian national forest inventory and airborne laser ... -
Temporal analysis shows relaxed genetic erosion following improved stocking practices in a subarctic transnational brown trout population
(Peer reviewed; Journal article, 2021-08-30)Maintaining standing genetic variation is a challenge in human-dominated landscapes. We used genetic (i.e., 16 short tandem repeats) and morphological (i.e., length and weight) measurements of 593 contemporary and historical ... -
