Naturtypen slåttemark er sterkt truet ifølge «norsk rødliste for naturtyper», og var i 2011 utvalgt naturtype (UN) med et visst vern gjennom naturmangfoldloven. I 2026 fikk NIBIO forespørsel fra Nannestad kommune om utarbeding av skjøtselsplan for område ved Tømte i Nannestad. Feltarbeidet ble gjennomført i juni 2026. Denne skjøtselsplanen gir restaurerings- og skjøtselsplanråd for ivaretakelse av de kulturavhengige naturtypene.

Abstract The utilisation of waste wood in cement-bonded composites addresses pressing ecological challenges by diverting municipal waste wood from incineration. In this study, a life cycle assessment (LCA) was conducted on a pilot-sized wood-cement composite board (1 × 1 m²; 18 mm thick) incorporating 25 wt% waste wood converted into wood chips. Environmental impacts were quantified for standard categories, including global warming, acidification, eutrophication, etc., in accordance with ISO 14044 guidelines. The results showed that Ordinary Portland cement was the dominant contributor to all impact categories, whereas the waste wood had negligible cradle burden. The composite product achieved a global warming potential of approx. 10.7 kg CO₂-eq., substantially lower than comparable cement-based composite boards on the market (14–32 kg CO₂-eq.). Primary energy demand of the boards was 40–70% less than that of commercial alternatives, benefiting from the use of bio-based waste and a cleaner energy mix in production. The composite boards exhibited a favourable environmental profile while maintaining acceptable mechanical performance for non-structural applications, thus providing a sustainable outlet for municipal waste wood. The findings support the viability of upcycling municipal waste wood into value-added building materials in line with circular economy goals.

The Norwegian Environment Agency has tasked The Norwegian Scientific Committee for Food and Environment (VKM) with developing generic guidance documents for environmental risk assessment of genetically modified organisms (GMOs) to be used in field trials. GMOs used in field trials may have effects on the environment, and human and animal health. All experiments involving the use of GMOs in field trails for research require approval under the Norwegian Gene Technology Act. The Norwegian Environment Agency is the decision-making authority for deliberate release of GM plants in field trials. VKM performs health and environmental risk assessments (ERAs) of genetically modified plants (GM plants) for the Norwegian Environment Agency. This guidance document is intended as a support for applicants seeking approval for field trials with GM plants under the Gene Technology Act. The risk assessments conducted by VKM generally follow the step-by-step approach outlined in EU Directive 2001/18/EC on the deliberate release of genetically modified organisms into the environment, starting with hazard identification, hazard characterization, exposure characterization and risk characterization. The Gene Technology Act and the Regulations on impact assessment under the Gene Technology Act implements Directive 2001/18/EC into Norwegian legislation. Appendix 2 of the Regulation contain the principles for environmental risk assessment, which corresponds to the principles of Annex II in the Directive. The European Food Safety Authority (EFSA) has developed further guidance on the risk assessment of genetically modified organisms based on Annex II. The guidance is based on guidance documents developed by the EFSA on risk assessment of GM plants. The document is divided into four main chapters: molecular characterisation, cross-cutting considerations, specific areas of risk to be addressed in the ERA, and risk-reducing measures. The guidance is intended to support applicants in identifying experimental data and scientific documentation necessary to include in an application to enable an independent risk assessment. The guidance is intended as a dynamic document to be amended in accordance with future scientific and regulatory developments.

Despite the growing use of heritagization in describing how food and food-related practices become cultural heritage, important questions remain regarding what characterizes heritagization and its internal dynamics. This article advances studies on heritagization by applying cultural adaptation work (CAW) to apple festivals. Whereas CAW has been conceptualized within Norway’s regime of geographical indications (GIs) as a rule-bound regulatory institution, we revise and extend that conceptualization by (i) relocating CAW to a hybrid institutional arena where protected GIs (PGIs) and festivals meet; (ii) specifying how CAW’s adaptive practices – translation, reorganization, and transformation – operate as mechanisms that generate recognition, legitimization, and valorization; and (iii) foregrounding festival publics, pedagogy, and experimentation as drivers of adaptation. Drawing on multi-sited ethnographic fieldwork in Norway at three apple-based PGI festivals and, for comparison, one non-PGI apple festival, we show how bottom-up festivalization recalibrates the top-down governance of GIs and yields both intended outcomes and unintended frictions. By shifting analysis from stage models to patterned work on living heritage, the CAW-in-GI-festivals approach makes adaptation practices visible and comparable across cases. In turn, it clarifies food heritagization’s internal dynamics and offers a lens on agri-food domains where de jure certification regimes intersect with de facto experiential publics.

Mange arkitekter og byggherrer velger i dag umalt trekledning fordi den krever mindre vedlikehold og får et naturlig uttrykk over tid. Men hva synes folk flest om den grå overflaten som utvikler seg når treverket står ute i vær og vind? En ny studie fra Norge, Sverige og Tyskland viser at flertallet av befolkningen fortsatt foretrekker malt trekledning. Samtidig er det store forskjeller mellom landene når det gjelder hvor godt folk aksepterer at treverket gråner naturlig. Resultatene tyder på at både kultur, erfaring og personlighet påvirker hvordan vi vurderer utseendet på trekledning.

Å velge trekledning handler om mer enn bare tekniske egenskaper. Utseende, vedlikeholds behov, kostnader og personlige preferanser spiller også en viktig rolle. En ny studie fra Norge, Sverige og Tyskland viser at bare én av fem foretrekker ubehandlet trekledning, og at både personlighet og lokale tradisjoner påvirker hva vi oppfatter som attraktive fasader. Med utgangspunkt i disse funnene har forskerne, som har utført studien, utviklet en enkel veiledning som kan hjelpe huseiere og byggherrer med å velge kledningsløsninger som passer deres forventninger til utseende, levetid og vedlikehold.

Hvor ofte folk vasker, maler og skifter ut trekledning varierer betydelig mellom land og mellom ulike brukergrupper. En spørreundersøkelse i Norge, Sverige og Tyskland viser at både erfaring, sosioøkonomiske forhold og personlighetstrekk påvirker hvor mye vedlikehold folk mener er nødvendig.
