Forest ecosystems will play a critical role in achieving policy targets for biodiversity and conservation, such as those set out in the EU Biodiversity strategy for 2030. However, practitioners need to know where forests of high conservation value are to make the best-informed decisions about which forests to prioritize. Here, we combine airborne LiDAR (airborne laser scanning/ALS), optical satellite imagery, and gridded datasets on soil and water availability with machine learning models to predict forests' conservation value across Denmark. We then use change-detection algorithms to identify forests that had been disturbed since the collection of the LiDAR data to produce up-to-date estimates for the year 2020. Our models reached a high predictive capacity (82% accuracy) and suggested that 1982 km2 (~31%) of Denmark's forests were of potential high conservation value. Our study demonstrates the utility of data fusion approaches to identify forest areas of high value for conservation at fine spatial resolutions (~10–100 m) and nationwide extents. However, uncertainties remain in our approach. Hence, our findings should be used to guide field-based assessments to confirm the in situ conservation value of the forests. Only in combination with such in situ data will approaches like ours enable decision makers to better protect forest biodiversity.

Quantifying the impact of biochar on carbon persistence across soil textures is complex, owing to the variability in soil conditions. Using artificial soils with precise textural and mineral compositions, we can disentangle the effects of biochar from the effects of soil particle size. We can show that biochar application significantly reduces the early-stage carbon mineralization rates of plant residues in various soil textures (from 5 % to 41 % clay) but more significantly in sandy soils. Clay and silt particles alone also reduce C mineralization, but the magnitude of the changes is negligible compared to the impact of biochar. This finding suggests that biochar can compensate for the lack of clay in promoting C persistence in soil systems. This short report contributes substantially to understanding soil texture and biochar application interactions.

Community supported agriculture (CSA) is a format for provisioning food, usually vegetables, where consumers are involved, to various degrees, in the production process. In this study of survey data, we explore differences between CSAs in Norway and the UK in terms of organisational models and member characteristics, particularly the factors that contribute to increase member contentment with CSAs, and their perceptions of their own mental health and vegetable consumption. Results show that compared to the British, Norwegian CSA members participate far more actively in the cultivation and harvesting of the vegetables, and more often prepay subscrip‑ tions for the whole season. In both countries, CSA membership was perceived to have caused improvements in members’ life quality, vegetable intake and physical and mental health. Members who participated more actively in the CSA and who received more of their vegetables through the CSA, were also more satisfied with their CSA and had a stronger perception that their vegetable consumption level and their mental health were positively affected by membership. Members with lower educational attain‑ ment levels were more likely to have discovered new vegetables through the CSA. Environmentally friendly production methods were also found to be important for CSA members. Vegetable quality and affordability were associated with higher content‑ment, and learning how to cook and grow vegetables through the CSA was associated with higher consumption of, and interest in, new vegetables. Overall, the results indicate that CSAs can stimulate contentment due to their members’ perceptions of social and environmental benefits.

Nord-Norge har svært gode utmarksbeiter for sau og samtidig en stor og uutnytta beitekapasitet. Paradoksalt nok er nedlegging av gårdsbruk og færre beitedyr den største flaskehalsen for økt bruk av utmarka i nord. I dialog med aktive beitebrukere i Nordland, Troms og Finnmark, har vi kartlagt årsaker til og virkninger av redusert beitebruk i Nord-Norge og foreslått hvordan en bærekraftig beitedrift kan opprettholdes og styrkes. Muligheter og begrensninger kartlagt i denne utredningen vil kunne gi et bedre grunnlag for kommunal planlegging og en politikkutforming for økt bruk av utmarka, og gjennom dette sikre det arktiske landbruket som en ryggrad i beredskap og bosetning i nord.
