Potato field management in Europe is already optimized for high production and tuber quality; however, numerous environmental challenges remain if the industry is to achieve “green economy” targets, such as less resources utilized, and less nitrate leached to the environment. Strategic co-scheduling irrigation and nitrogen (N) fertilization might increase resource use efficiency while minimizing reactive losses such as nitrate leaching. This study aimed to quantify the combined effect of irrigation and N fertilization on potato production, growth, and resource use efficiencies. A field experiment was conducted from 2017 to 2019 on a coarse sandy soil in Denmark, with a drought event occurring in 2018. Full (Ifull, maximized), deficit (Idef, 70–80 % of Ifull) and low irrigation treatments (Ilow, minimized amount to keep crop survival), each under full (Nfull, maximized) and variable (Nvar, variable amount according to the crops’ needs) N fertilization were applied. The analyses results show that Ilow limited potato growth under a drought-heat event; otherwise, potato growth was comparable between Ifull and Idef treatments, with 31–32 % higher irrigation efficiency (IE) under Idef than under Ifull. Nitrate leaching was variable and not significantly different among the treatments, being in general 9–13 % lower under Idef in absolute terms than under Ifull. Unexpectedly, outcomes from Nvar were statistically lower compared to those from Nfull. Radiation use efficiencies (RUEs) from Ilow and Nvar were significantly lower than from Ifull and Idef (14–19 %), and from Nfull (9–11 %). N use efficiencies (NUE) were comparable between N fertilization treatments but significantly different among different irrigation treatments. Overall, this study confirms that Idef is the best irrigation strategy. Future efforts should focus on developing improved approaches for detecting in-season crop N status and further quantifying N requirements, as well as promoting the co-scheduled management of irrigation and N fertilization. Remote sensing approaches have great potential to assist with this.

Agrivoltaics, also known as solar sharing or agri-PV, represents a pioneering con- cept that seeks to optimise land use by combining agriculture with photovoltaics on the same land area. While research and development on this topic have increased significantly, few studies address the issue in the Continental Subarctic Climate zone. In this paper, we report on the modelling and installation of a 48 kWp agrivoltaic system at the Skjetlein High School in Trondheim (Norway, lat. 63.34), which is currently the highest latitude system in the World, and we present the initial results of the impacts of the system on Timothy grass biomass. This work takes the first steps towards realising agrivoltaic opportunities for a broad area of Norwegian agriculture.

Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively managed landscapes remains poorly understood. We analyzed 953 occurrences of wild bees comprising 79 nonparasitic species sampled at 68 study sites across a Norwegian and a Danish landscape. We first tested whether bee species richness was positively associated with the lengths of seminatural LLS in bee foraging ranges of study sites while controlling for local plant species richness. We then combined maps identifying seminatural LLS with least‐cost path (LCP) analysis to determine whether bee species compositional similarity, a proxy for connectivity, decreased as LCP length increased. The length of seminatural LLS, such as forest edges, was positively correlated with bee species richness and habitat connectivity. Specifically, wild bee species richness sampled along roadsides increased as the length of seminatural LLS increased in 1.5 km circles around the study sites, and increased as local plant species richness increased. The most likely dispersal routes between our bee communities tracked forest edges. The length of LCPs provided better models of bee species compositional similarity than geographic distance, suggesting that seminatural LLS, particularly forest edges, act as dispersal corridors in intensively managed landscapes. However, bee species compositional similarity among communities depended on site‐specific plant species richness and similarity in plant community composition, which highlights the importance of improving the habitat quality of seminatural LLS if they are to function as dispersal corridors. Our findings suggest that maps of LCPs can be used to identify important dispersal corridors between bee habitats and to direct wild bee habitat management actions along seminatural LLS to facilitate the dispersal of bees in intensively managed landscapes.

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.
