In Norway, agroclimatic zones (ACZs) are a valuable tool for national analyses in subject areas concerning the optimized management of agricultural land resources. However, current Norwegian ACZs have been criticized for having an outdated standard climate normal (1931–1960), a limited representation of the local climatic variation, a lack of important model parameters, and weak methodological documentation. Therefore, this paper presents new ACZs for Norway that address these weaknesses. The most significant methodological updates are the use of the standard climate normal of 1991–2020, additional weather data variables, the downscaling of weather data to 250 m hexagons, and the incorporation of phenological crop models for spring wheat, spring barley, and forage grass. The grass model was calibrated with the number of grass harvests at research stations, while the grain models were calibrated with subsidy claim data. The modeled zones for the three crops were combined into the general ACZs. Example maps of the crop zones and new ACZs for the selected regions and the whole country are presented. The new ACZs are more robust, agronomically relevant, and better aligned with the current climatic conditions in Norway. The deliberate exclusion of factors other than climate ensures the new ACZs’ national comparability and their applicability in policy development, land-use planning, climate adaptation, and agronomic assessments at the national scale.

This study has applied FAO’s resilience assessment tool «SHARP+» to 14 farm enterprises practicing mountain summer farming (stølsdrift) in the Valdres region, representing the first use of this tool in a Norwegian context. The questionnaire was adapted to better capture local agricultural practices and institutional conditions, and structured interviews with farm managers were conducted in November 2025. Technical resilience scores ranged from 4.9 to 7.4 out of 10 (mean 6.2), and self-assessed scores from 5.9 to 7.9 (mean 6.9). The strongest areas were Government and institutional support (9.3) and Education and knowledge (8.5). The weakest were Livestock nutrition (3.5), Reasonably profitable (3.8), and Globally autonomous and locally interdependent (3.2), pointing to structural constraints related to feed self-sufficiency, farm profitability, and dependence on external inputs. Self-assessed scores consistently exceeded technical scores, particularly in production-related modules. Farmers' stated priorities — climate adaptation, infrastructure, farm economy, cooperation, and policy — largely aligned with the weakest areas in the technical assessment. The 2018 drought was the most critical environmental event reported by ten of the fourteen interviewees during their career as farmers.

Norske stølsbønder har god tilgang til kunnskap og offentlig støtte, men er sårbare når det gjelder økonomi, grovfôrproduksjon og klimaendringer.

Afforestation of agricultural land is widely promoted as a nature-based solution to enhance carbon (C) sequestration and mitigate atmospheric CO2 levels. However, the temporal dynamics of soil organic carbon (SOC) after afforestation, particularly in mineral soils, remain uncertain due to the complex interaction of biogeochemical processes and their spatial variability. We investigated changes in SOC sequestration over five decades of afforestation on former cropland by extending the chronosequence approach with three repeated soil inventories in oak (Quercus robur L.) and Norway spruce (Picea abies (L.) Karst.) stands. Aboveground biomass C stocks were also quantified to evaluate the contribution of SOC to post-agricultural ecosystem C stocks. Forest floor C stocks increased rapidly in the early years and stabilized after approximately three decades, with consistently higher accumulation under Norway spruce than oak. In contrast, mineral SOC stocks in 0-25 cm depth increased with forest age by 0.18 ± 0.06 Mg ha−1 yr−1 under oak and 0.44 ± 0.07 Mg ha−1 yr−1 under Norway spruce. These contrasting trends in forest floor and mineral soil indicated a shift in C source-sink strength over time and between species. After 50 years of afforestation, total ecosystem C stocks in afforested stands reached up to 75% of those in a 200-year-old forest, with most new C stored in biomass (84-86%), followed by mineral soil (10-11%) and forest floor (4-5%). Despite higher sequestration of new C in Norway spruce stands, the relative distribution across ecosystem compartments was similar between tree species.

Rapporten gir en oversikt over klimarisiko for noen jordbruksproduksjoner i Trøndelag. Basert på forventede endringer i klima er det vurdert både muligheter og utfordringer for korn, grovfôr og grønnsaksproduksjon i Trøndelag. I klimatilpasning er det vektlagt kunnskap om lokalt jordsmonn for tilpasning av drenering, maskiner og jordarbeiding, tilpasning av vekster og agronomisk praksis. This report gives a short overview of climate risk for certain agricultural productions in Trøndelag. Based on expected changes in climate both opportunities and challenges are included for cereal, fodder and vegetable productions. Knowledge about soil and soil quality for adaptation of drainage, soil tillage, machinery and choice of crops and agronomic practice is emphasized.

Background and aims Cover crops are an important measure for carbon (C) sequestration in agriculture. However, little is known about the potential of cover crops to increase C under Nordic conditions and the efficiency of this measure over time. Here, we quantify the potential contribution of different cover crops to soil organic carbon (SOC) and organic matter fractions, and study how this is affected by the origin of the C input (aboveground or belowground residues). Methods We conducted a 13 CO 2 pulse-labelling experiment during the growing season of four cover crops adapted to Nordic conditions, representing different plant functional types. The assimilated 13 C was traced in soil during the following two years. We investigated the fate of cover crop C in two organic matter fractions, Particulate Organic Matter (POM) and Mineral-Associated Organic Matter (MAOM), known to have different persistence in soil. Results Carbon derived from aboveground residues decayed two to three times faster as compared to belowground C. Belowground C inputs were similar among cover crops despite their contrasting root traits and differences in root biomass C. Rhizodeposited-C was consistently the largest belowground C input. Cover crop species affected the quantity of POM-C and MAOM-C, but MAOM-C was preferentially formed from belowground C (ranging from 0.63 ± 0.2 to 0.25 ± 0.1 Mg MAOM-C ha −1 across different cover crops), regardless of the species. Conclusions Cover crop species that can combine large belowground biomass production with root traits that promote physical and physico-chemical protection of OM will contribute most effectively to the long-term SOC pool. These aspects need to be balanced with considerations related to agricultural management.
