Capping is an effective method for reducing internal nutrient loading in eutrophic water bodies, but research on low-cost materials, especially for trapping nitrogen and phosphorus, remains limited. This study evaluates the performance of a dual-layer biochar and zeolite capping system in mitigating nutrient fluxes. The structural and compositional properties of the materials were characterized using advanced techniques such as scanning electron microscopy, electron diffraction spectroscopy, and Raman spectroscopy. Three setups at 16 C and 24 C were tested for 60 d: (1) uncapped sediment, (2) nonwoven fabric mat (NWFM) with zeolite over biochar, and (3) NWFM with biochar over zeolite. Both capping configurations significantly reduced ammonium-nitrogen flux. The zeolite-on-top setup achieved the lowest total nitrogen flux at 16 C (1.03 mg/m2/d), while uncapped sediment had the highest at 24 C (5.02 ± 1.36 mg/m2/d). Zeolite at the top layer enhanced nutrient retention—up to 95% ammonium and 98% phosphorus—while maintaining dissolved oxygen and reducing chemical oxygen demand. These results highlight the short-term efficacy of dual-layer capping as a cost-effective approach for lake restoration. Further field-scale studies are recommended to assess long-term outcomes.

One of the UN’s 17 sustainable development goals (SDGs), SDG 7, is to “ensure access to affordable, reliable, sustainable and modern energy for all.” This goal addresses the need for environmental sustainability while highlighting energy’s vital role in promoting social and economic justice. It calls for sustainable, affordable, modern, and reliable energy usage for the health and well-being of society while mitigating climate change. Here, we briefly review available literature and data to examine how renewable energy, food security, and sustainability are interconnected in Arctic countries and regions, and how these regions can “ensure access to affordable, reliable, sustainable and modern energy for all” and progress towards achieving food self-sufficiency by integrating renewable energy sources into food production systems. We analyze several case studies to draw conclusions on how Arctic communities can become resilient, sustainable, and economically prosperous by promoting local food production while preserving cultural practices.

Carrot (Daucus carota L. subsp. sativus) is a major vegetable crop in Norway which is stored up to 9 months in refrigerated storage rooms. Postharvest storage losses—primarily from water loss, respiration, and fungal decay—can reach up to 30 %. This study investigated the effects of different postharvest pre-storage strategies involving wound healing (WH) and temperature adaptation (TA) on mass loss, respiration rate, polyacetylene content, and disease development in four carrot cultivars (Nelson, Triton, Nominator, and Romance) during long- term storage. Carrots were subjected to six pre-storage strategies combining WH at 10 ◦ and various TA regimes (directly to 0 ◦ C or 1 ◦ C (60 % or 95–98 % RH) C reduction/day), followed by storage at 0 ◦ C for six months. Data showed that WH at high humidity, followed by gradual cooling, reduced disease incidence and increased the accumulation of antifungal polyacetylenes such as falcarinol and falcarindiol-3-acetate. Respiration rates were initially higher under WH treatments but did not result in increased total storage losses. Rapid cooling without WH led to higher disease levels, particularly in the cultivars Nelson and Romance. The findings support the implementation of a wound healing period prior to temperature reduction as a strategy to reduce postharvest decay and improve carrot storage quality, especially under commercial storage conditions where cooling rates may vary.

As the EU intensifies its climate ambitions with the upcoming 2040 targets, it is crucial to understand how implementation of existing EU climate policies is going. How well are current policies working on the ground? Are we on track – or are there gaps that need urgent attention? As the debate around the 2040 targets heats up, this policy brief provides a timely assessment of how existing policies play out in practice and to what extent and how implementation varies across countries. Looking at Norway and Denmark, we compare the implementation of three EU regulations, which were revised in 2023: the EU Emission Trading Scheme (ETS), the Effort-Sharing Regulation (ESR) and the Land Use, Land-Use Change, and Forestry (LULUCF) sector.

I prosjektet ‘RobustRubus’ er et av målene å finne nye sorter av bringebær for dyrking i plasttunnel med mulighet for høsting fra juni til oktober. På NIBIO Apelsvoll ble det i 2022–2025 testet til sammen 24 sorter og seleksjoner av både norske og importerte sorter og langskudd-planter. Det ble gjort registreringer av avling og avlingskomponenter, samt bærkvalitet og smak. Sortene ‘Duo’, ‘Glen Ample’, ‘Lagorai Plus’, ‘Ninni’ og ‘Sequoia’ ble etter fire år med testing vurdert til å være best egnet til dyrking i plasstunnel.

Rapporten undersøker relasjonen mellom bærekraftige lokalsamfunn og landbruk, med særlig fokus på arktisk landbruk. Med utgangspunkt i en litteraturstudie og innspill fra faglige møteplasser (2023–2024) viser rapporten at lokalsamfunn gir infrastruktur, tjenester og sosiale nettverk, mens landbruket bidrar med sysselsetting, beredskap, kulturlandskap og kulturell verdi – også i samiske lokalsamfunn. Litteraturstudien viser at vi må forstå hvordan landbruk og lokalsamfunn henger sammen for å kunne møte utfordringene i det arktiske landbruket. Rapporten peker også på utfordringer, blant annet strukturendringer, svake økonomiske marginer, fraflytting og sårbar logistikk. Studien viser at vi trenger mer kunnskap om samspillet mellom landbruks- og distriktspolitikk, samisk jordbruk og lokale perspektiver på nærings- og samfunnsutvikling. Rapporten setter søkelys på behovet for en mer helhetlig politikk, sterkere praksisfellesskap og regionale matsystemer for å sikre robust matproduksjon og livskraftige steder i nord.

The global loss of biodiversity and natural capital, driven by land use change, poses a risk for vital ecosystem services, such as air and water filtration, food provisioning, and wellbeing. Ecosystem accounting is a framework for documenting ecosystem extent, condition and the services which they produce. Questions remain about the way in which this new framework can be implemented and utilised in spatial planning. Using Norway as a case study, we perform a requirements analysis of its current spatial planning system, drawing on qualitative data from planning professionals and planning policy documents, to understand the contemporary problems within planning related to the use of ecological data. Ecological data is currently produced to adhere to the knowledge deficit model of decision making, whereby more data and knowledge lead to better decisions. However, our current communicative planning system relies on participation for knowledge gathering, which becomes an issue when the scope, communication method, and timing of communication are barriers to knowledge being used in a decision. We therefore propose a new theoretical model, PRISM, based on the analogy of a prism, as its purpose is to break ecological data up to meet the diverse objectives of, and thus engage with, as many actors as possible. The analogy is derived from the finding that ecological data and knowledge constitutes only one band in the spectrum of considerations and knowledge used in decisions. Framing is proposed as the method to achieve this effect with ecosystem accounting data, thereby activating participation to meet policy and actor objectives.
