This report reviews the potential use of seaweed as a feed ingredient for ruminants under Northern-Norwegian conditions. Seaweed has a long history in coastal livestock farming, especially where conventional forage was scarce, but its use declined as farms became larger, more specialised and dependent on high-quality feeds. Renewed interest is driven by the need to increase national feed self-sufficiency, reduce reliance on imported protein sources, and explore strategies to lower enteric methane emissions. Seaweed species differ greatly in nutritional value, digestibility, mineral composition and effects on rumen fermentation. Red species such as Porphyra and Palmaria palmata appear most promising as protein sources, whereas several brown species show lower protein digestibility and may contain high iodine levels or potentially harmful elements. Preservation is a major barrier because fresh seaweed decomposes rapidly; ensiling, drying and multi-nutrient blocks require further development to improve dry matter content, palatability, shelf-life and nutrient quality. Seaweed has also been studied as a methane inhibitor. Asparagopsis can strongly reduce methane emissions, but concerns about bromoform content, animal health, productivity and suitability for Norwegian systems limit its relevance. Norwegian studies with locally available seaweeds have not shown consistent in vivo methane mitigation. Overall, seaweed may support more circular and locally based feed systems, but practical use requires species-specific evaluation, safe inclusion levels, improved preservation methods and stronger in vivo documentation.

Foreliggende rapport er en utredning av konsekvensene for reindriftsnæringen ved utvidelse av Sulitjelma fjellandsby Daja, i Fauske kommune. Tiltaket omfatter etablering av 167 nye boenheter (hytter og fritidsleiligheter), interne adkomstveier, tilhørende infrastruktur samt en mindre utvidelse av alpinbakken med nytt garasjebygg for tråkkemaskin. Balvatn reinbeitedistrikter vil bli berørt av tiltaket. Det er forventet at det er de indirekte virkningene av hyttebygggingen i form av økt ferdsel i forbindelse med friluftsliv inn i sentrale beiteområder som utgjør den største belastningen for reindrifta. Det er foreslått skadereduserende tiltak for å reduserer de negative konsekvensene for reinbeitedistriktet.

Climate change is intensifying floods, droughts, and nutrient export from agricultural landscapes, threatening water security under increasingly non-stationary hydroclimatic conditions. Although landscape-scale water-retention measures are widely promoted as nature-based solutions, their combined effectiveness under future climates remains poorly constrained, particularly across contrasting hydroclimatic settings. Here, we evaluate the capacity of distributed retention portfolios to buffer climate-driven hydrologic and water-quality change using a harmonized, field-explicit Soil and Water Assessment Tool Plus (SWAT+) framework applied to five European agricultural catchments spanning a pronounced hydroclimatic gradient. Portfolios, co-designed with local stakeholders, were simulated under historical and late-century climates drawn from bias-corrected Coordinated Regional Climate Downscaling Experiment over Europe (EURO-CORDEX) simulations. Impacts were assessed for flood peaks, low flows, soil-moisture drought duration, and nutrient or sediment export. Climate change consistently amplifies hydrologic extremes and pollutant loads, particularly under wetter future conditions. Retention portfolios reduce flood peaks and pollutant export across all catchments but provide only limited improvements in low flows and drought duration. However, portfolio effects rarely offset climate-driven changes, indicating that retention primarily functions as a risk-reduction strategy rather than a means of restoring baseline conditions. Portfolio effectiveness showed weak associations with the catchment dryness index and varied among catchment-specific portfolios. Because hydroclimate, catchment properties, measure composition, and spatial placement covary in this comparative design, their independent effects cannot be separated. The results nevertheless identify measure-pathway alignment and hydrologic connectivity as plausible design considerations. Responses were predominantly co-beneficial across indicators, indicating that portfolios can deliver multiple co-benefits with limited trade-offs. These findings position distributed retention portfolios as a useful but inherently limited component of climate adaptation, underscoring the need to combine retention with complementary strategies to manage residual risks.
