EPPO-listed plant pests were assessed and ranked according to the overall risk they pose to Norwegian plant health. Based on probability of entry, probability of establishment (including spread), and potential impact on plant health, pests were classified into five risk classes: very high, high, moderate, low, and very low risk. In this second progress report VKM has assessed 69 pests: 53 insects and mites, eight bacteria, four viruses, three fungi, and one chromista. No pests were assessed to pose very high or high risk. Six pests were assessed to pose moderate risk: Choristoneura fumiferana, Dendrolimus superans, Grapholita packardi, Potexvirus pepini, Tobamovirus fructirugosum, and Xylella fastidiosa. The remaining 63 pests were assessed to pose low risk (20 pests) or very low risk (43 pests) to Norwegian plant health.

Betaphycus gelatinus is a red seaweed with emerging commercial interest due to its potential as a source of high-quality carrageenan and bioactive compounds. Despite its promise, there remains a lack of established cultivation techniques for this species. Here, we provided a comprehensive assessment of the strain-specific performance of B. gelatinus grown in land-based cultivation systems, focusing on growth and its seasonality, morphological transformation, and a snapshot biochemical analysis at the end of a one-year cultivation period. Three B. gelatinus strains, namely KU9-PGD, KG1-PGD, and K-PGD, were collected from field and maintained in a land-based culture system. Significant differences in growth rates were observed among strains, with generally higher values recorded during the inter- and southwest monsoon (0.78 – 3.09, 1.74 – 4.41, and 1.79 – 5.45% d−1, respectively) compared to northeast monsoon (0.49 – 1.44, 1.25 – 2.12, and 1.20 – 3.97% d−1, respectively). Among the three strains, K-PGD exhibited the most robust growth, underscoring the importance of strain selection in optimizing biomass yield. Growth rates also varied between cultivation systems, with glass aquaria (1.30 – 2.87% d−1) promoting higher growth rates than concrete tanks (1.15 – 1.75% d−1). The domestication of B. gelatinus resulted in morphological transformation where changes in branching, pigmentation, and thallus surface features emerged compared to their respective original wild forms. During the southwest monsoon sampling, biochemical profiles (pigments, carbohydrates, proteins) of the three strains remained relatively uniform under controlled conditions. These results affirm the potential of B. gelatinus as a viable crop for future commercial mariculture and provide valuable baseline information for developing cultivation protocols and selecting high-performing strains for large-scale production.

Abstract
This paper examines the effect on employment and Greenhouse Gas (GHG) emissions if legume production and consumption in Norway increase and replace animal-based proteins. Three scenarios—maximising employment and cultural landscapes, minimising GHG emissions and evenly reducing each type of livestock—were analysed. Results show that increasing legume production and consumption can significantly reduce GHG emissions but also reduce employment in the livestock sector. This demonstrates a trade-off between reducing GHG emissions versus maintaining cultural landscapes and employment opportunities in rural areas where other income opportunities may be scarce.
