Soil disturbance following forestry operations is influenced by multiple factors. Reducing disturbance requires placing strip and base roads in locations with minimal risk of disturbance. However, identifying these areas is a complex task. To address this, we have begun developing a forwarding risk index ranging from 1 to 100 that integrates several geographical information sources in the area around Oslo. This forwarding index seems to provide good estimates of areas with a higher risk of ground disturbance during forwarding operations at the sites used for development. With further development of geographical inputs, their combination into a risk index, and later on nationwide validation, the forwarding risk raster combined with a terrain map could improve the identification of suitable areas for forwarding trails. The risk raster was tested for path planning and performed well in areas with a low to moderate frequency of high-risk pixels but was less effective in areas with a high concentration of high-risk pixels. In these areas, an assessment of the potential ecological impact (erosion, sedimentation of streams, mobilisation of mercury, soil carbon impact, changes in hydrology, soil compaction) of ground disturbance is needed alongside the risk index to determine the least unsuitable trail locations.

Food self-sufficiency and local food production are increasingly important in the context of global supply chain uncertainty. In Northern Norway, sustaining agricultural activity is central to national food preparedness, yet vegetable production in Arctic municipalities remains limited. In this study, we examine how vegetable production can be enhanced in Nordreisa municipality by exploring barriers, opportunities, and stakeholder perspectives. Using a qualitative single-case study design, we investigate local realities that shape the current lack of vegetable production through semi-structure interviews with diverse stakeholders across the regional food system and a local interest in vegetable production survey. We found that systemic barriers such as limited infrastructure, fragmented markets, and governance gaps constrain immediate growth. At the same time, motivated producers, consumer interest in local food, and a shared desire for self-sufficiency indicate a latent potential for development. This study suggests that increasing local vegetable production requires a dual approach: grassroots initiatives that mobilize local actors and supportive governance that enables implementation. Practical measures include the establishment of local storage and distribution facility, fostering collaboration between producers and consumers, and aligning municipal and national policies with local capacities. Through the enhancement of social networks and institutional support, municipalities like Nordreisa can take concrete steps towards strengthened local vegetable production.

Sjokoladeflekk er en av de mest alvorlige sjukdommene som rammer åkerbønne og finnes over hele verden der åkerbønne dyrkes. Sjukdommen forårsakes av ulike arter i soppslekta Botrytis, hovedsakelig Botrytis fabae og Botrytis cinerea, som kan angripe alle overjordiske plantedeler. Tidlige utbrudd viser seg som små, spredte mørkebrune flekker på bladene. Ved fuktig og varmt vær (15-22 °C) utvikler sjukdommen seg raskt ved at flekkene vokser sammen og etter hvert vil bladene visne og falle av, noe som kan gi betydelige avlingstap på grunn av redusert fotosyntese. Infeksjon i blomster reduserer belgsetting. Angrep tidlig i sesongen (før og ut blomstringa), kan gi total skade. Frøsmitte er en viktig smittekilde for B. fabae.
