Publikasjoner

NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Ny forskning viser at jo mer tid rein bruker på å tygge drøv, desto mindre søvnige blir de. Drøvtyggingen reduserer dyras søvnbehov om sommeren, noe som gir mer tid til å finne mat.

Stadig mer skog vernes, og mer av naturskogen befinner seg i områder der hogst ikke er tillatt. Samtidig skorter skogvernet i produktiv skog på høy bonitet.

Bjørk er mer enn bare ved. Treslaget brukes til møbler, panel og knivemner og er en viktig del av nordisk design. En ny rapport fra NIBIO viser potensialet for mer kvalitetstilpasset bruk av bjørk.

Forests plays many vital roles: They provide a natural habitat for animals, plants and other organisms. They contribute to soil protection and water conservation, carbon storage and clean air. Moreover, forests promote economic growth through providing essential goods and services for humans such as timber and food, in addition to a wide variety of products to replace fossil resources in a biobased economy. They are also popular places for outdoor recreation. For forests to thrive, it is important that they are managed in a sustainable way balancing the various ecosystem service demands. Most of these demands are mentioned in different national forest policies. However, such policies often focus on potentially conflicting societal needs, and are mostly developed in non-coordinated processes, both in Norway and other countries. This has created incoherences in design and implementation, leading to policies with conflicting targets. In the international collaborative project MultiForest, scientists have looked at how expectations for forests can be met in a better way in four countries Sweden, Finland, Norway and Germany.

Jordbruket forvalter store nitrogenressurser. Nitrogen er avgjørende for matproduksjonen, men har negativ effekt på klima og vannmiljø om det kommer på avveie. I en ny rapport presenterer NIBIO en rekke tiltak som kan bedre utnyttelsen av nitrogen i jordbruket.

Sustainable forest management systems require operational measures to preserve the functional design of forest roads. Frequent road data collection and analysis are essential to support target-oriented and efficient maintenance planning and operations. This study demonstrates an automated solution for monitoring forest road surface deterioration using consumer-grade optical sensors. A YOLOv5 model with StrongSORT tracking was adapted and trained to detect and track potholes in the videos captured by vehicle-mounted cameras. For model training, datasets recorded in diverse geographical regions under different weather conditions were used. The model shows a detection and tracking performance of up to a precision and recall level of 0.79 and 0.58, respectively, with 0.70 mean average precision at an intersection over union (IoU) of at least 0.5. We applied the trained model to a forest road in southern Norway, recorded with a Global Navigation Satellite System (GNSS)−fitted dashcam. GNSS-delivered geographical coordinates at 10 Hz rate were used to geolocate the detected potholes. The geolocation performance over this exemple road stretch of 1 km exhibited a root mean square deviation of about 9.7 m compared to OpenStreetMap. Finally, an exemple road deterioration map was compiled, which can be used for scheduling road maintenance operations.
