Only approximately 2% of the land area in Northern Norway is suitable for agricultural purposes. The short growing season and cold climate impose limitations for what can be produced. Agriculture still takes place here, with forage crops for livestock being the most important. On free rangeland areas, including both semi-natural and natural habitats, livestock grazing is common. The biomass production on some of these rangelands is presumed to be high, although little is known about the actual fodder potential. In 2022 a preliminary study was performed to determine abundance and variety of wild pasture plants, dry matter yield (DM) and feed quality in the (presumed) highest yielding Vegetation types. Results showed an average of 1520 kg DM ha–1 in spring and 5380 kg DM ha–1 in autumn. Early season feed quality was high, but with rapidly decreasing trends. The number of pasture plants was also high. Our results show that in sub-arctic Northern Norway grazing animals can harvest substantial amounts of ‘free’ fodder of good quality, yet the official statistics show that only 14% of this resource is utilised. Continuous grazing is needed to maintain production and fodder quality in these areas.

We address the question of nature-culture synergies in protected mountain landscapes with a specific focus on the Norwegian National Park of Hardangervidda. Fragile and complex ecosystems developed from long-lasting socio-ecological grazing processes that started approximately 4000 years ago in Scandinavia are facing manifold environmental challenges and societal issues that endanger both natural and cultural heritages. Our goals are to clarify the nature-culture synergies and relationships and investigate holistic management and preservation of natural and cultural values. Our results highlight an urgent need to develop holistic conservation frameworks and methodologies for protected landscapes that integrate cultural and natural heritages and enhance the potential of local communities to protect threatened semi-natural environments and experienced-based knowledge for the future.

The Climate Laboratory in Tromsø offers excellent facilities for controlled growth experiments. In an attempt to provide for future needs to perform qualitative and quantitative analysis of plant growth and plant traits at the laboratory scale, UiT and NIBIO have jointly implemented state-of-the-art monitoring and imaging systems as part of the strategic project ABSORB (https://site.uit.no/absorb/). Here, we present a 3D multi- and 2D hyper-spectral imaging platform, augmented with thermal analysis capabilities, tailored for plant phenotyping in both research and teaching contexts. The 3D imaging component of the PlantEye F600 laser scanner provides effortless and accurate non-invasive assessments of plant architecture and growth dynamics. Three complementary 2D hyperspectral cameras deliver more detailed spectral information across a 400-1700 nm range of wavelengths, supporting in-depth analysis of biochemical composition and stress responses at the macro- and micro-scales. We showcase the platform's versatility through two compelling experiments investigating drought-stress and light-inhibition, respectively. In the drought-stress experiment, we observed plant responses to water scarcity, tracking physiological changes and morphological adaptations with our integrated imaging system. In the light-inhibition experiment, we further explored the impact of light intensity on plant growth and development. We envision collaborative efforts to address the current challenges in plant biology, agriculture, and environmental science.
