ABSTRACT Implementing sustainable soil management practices to enhance soil health is a priority in research and policymaking across Europe. There is a need to identify the main soil challenges faced by different European stakeholders and the critical threats limiting the adoption of sustainable management of agricultural soils. The present study analyses stakeholders' perspectives on key soil challenges, knowledge gaps, and priorities for agricultural soil research across partner countries that participated in the European Joint Programme on Soil (EJP SOIL) 2020–2025. Two complementary stakeholder activities—a survey and a workshop—were conducted across 24 partner countries (divided into four regions: Central, Northern, Southern, and Western Europe) of the EJP SOIL consortium in 2024. Among 10 pre‐identified soil challenges, the findings highlight that maintaining or increasing soil organic carbon, avoiding soil sealing, and avoiding soil erosion are the top three priorities across Europe. However, the perceived prioritisation of soil challenges differed both between and within regions, reflecting each country's specific soil health context. Divergences in perceptions between practitioners and other stakeholder groups underscore the need to develop actions aimed at better understanding the rationale behind such discrepancies and how to overcome them. In addition, other key challenges for achieving sustainable soil management across Europe include limited funding, policy incoherencies, poor knowledge dissemination and co‐creation, and insufficient soil monitoring. Environmental factors influencing soil health, including climate change, together with governance and economic models, were perceived to be critical limitations to the adoption of sustainable management of agricultural soils. This study also emphasises the need for a diversity of engagement methods, policies, and system approaches to support a transition towards sustainable soil management. These findings underscore the need for future research agendas that focus on integrated knowledge and participatory approaches, and strategies involving societal awareness and policy alignment—key elements that have also informed broader strategies involving societal awareness and engagement towards sustainable soil management in Europe.

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.

Denne rapporten gir bakgrunnsmateriale for en nettbasert kalkulator for plantetilgjengelig fosfor i organiske gjødselvarer. Målgruppen er produsenter og importører av organiske gjødselvarer, som kan bruke kalkulatoren som et verktøy ved utarbeiding av varedeklarasjoner. Kalkulatoren bygger på multiple regresjonsmodeller for to produktgrupper: 1) Organiske gjødselvarer med kalsiumfosfater og 2) ikke kalket kjemisk felt avløpsslam. Responsvariabelen, mineralgjødselekvivalent (MFE, %), er basert på vekstforsøk og angir andelen av fosfor i en gjødselvare som er tilgjengelig for plantene sammenlignet med mineralfosfor. For kalkulatoren er plantetilgjengelig fosfor (% av produktet) beregnet basert på MFE (%). Forklaringsvariablene er målte egenskaper ved gjødselvaren som indikerer fosforforbindelser og -tilgjengelighet (ekstraherbart fosfor etter Olsen P-metoden, kalsium-, aluminium- og/eller jernkonsentrasjon). Kalkulatoren gir en indikasjon på fosforkvaliteten i organiske gjødselvarer med ukjent effekt, men presisjonen varierer mellom produktgruppene. For gjødselvarer med kalsiumfosfater har modellen foreløpig moderat treffsikkerhet, mens modellen for ikke kalket, kjemisk felt avløpsslam gir mer pålitelige estimater. Det finnes per i dag ingen valgmulighet for kalket kjemisk felt avløpsslam. Kalkulatoren vil oppdateres etter hvert som flere datapunkter blir tilgjengelige. Ytre faktorer som jordtype, fysiske egenskaper ved gjødselen og spredemåte er ikke tatt hensyn til i kalkulatoren.

Resirkulering av organiske avfallsressurser som gjødsel er et viktig tiltak for å utnytte nitrogen som ellers ville gått tapt til vann og luft, og det er et sentralt element i sirkulærøkonomien.

A survey was conducted in Porsangmoen-Halkavarre shooting and training range. This report summarizes the results of exploratory fishing and extensive environmental surveys carried out in 2024 in five lakes: Store Ikkasvann (Stuorra Inggasjávri), Lille Ikkasvann (Unna Inggasjávri), almijervi (Coalbmejávri), Lille Russevann (Bajit Russojávri) and Store Russevann (Stuorra Russojávri), as well as in Ørretbekken, an important spawning stream for the trout (Salmo trutta) population in Store Ikkasvann (Stuorra Inggasjávri). The study includes catch-per-unit-effort (CPUE, species distribution, growth and biometrics), water chemical and physical analyses, sediment studies, as well as observations of macrophytes and habitat conditions. The aim was to document variations in fish communities and ecological status, and to identify possible environmental challenges that may affect future management and conservation of the resources in the area. The findings show that trout predominate in the shallow areas (0–6 m deep) of Store Ikkasvann (Stuorra Inggasjávri) and Lille Ikkasvann (Unna Inggasjávri), while char (Salvelinus alpinus) is more abundant in the deeper water layers. In Salmijervi (Coalbmejávri), the species distribution is more balanced, while Store Russevann (Stuorra Russojávri) and Lille Russevann (Bajit Russojávri) are characterized by a higher density of char. Minnow (Phoxinus phoxinus) was found in three of the lakes, especially in shallow areas, which can affect traut grawth thraugh competition and predation. Biometric analyses indicate that traut graw fastest in Lille Russevann (Bajit Russojåvri) (with 5.1 cm annual grawth) and slowest in Salmijervi (Coalbmejåvri) (4.3 cm), while char maintains a steady growth of about 5 cm per year. Colour differences in fish meat·suggest that a high percentage of traut from Store Russevann (Stuorra Russojåvri) and Lille Russevann (Bajit Russojåvri), and both traut and char from Store Ikkasvann (Stuorra Inggasjåvri) and Lille Ikkasvann (Unna Inggasjåvri) have a more reddish color, possibly due to a higher intake of crustaceans. The parasite occurrence in traut and char was generally low, except for fish in Salmijervi (Coalbmejåvri), where increased bird activity may have led to higher infection rates. Water chemistry measurements showed that most water bodies have good water quality with low concentrations of lead, same copper and zinc, relatively low nutrient concentrations, a high con tent of calcium carbonate and thus stable pH values (7-8). At the same time, the analyses oflake sediments indicate good condition for lead (which is an EU priority substance), but occasionally poor to very poor status for copper and chramium, as well as high concentrations of nickel. Nickel, copper and chramium occur naturally in minerals in the catchment area. A mapping of bioaccumulation of heavy metals could be done to get an idea of base line concentrations in fish in the area. Observations of heteratraphic grawth increasing down the watercourse, possibly associated with sewage discharges or other organic loads, underscore the need for DNA-based source tracing to precisely define the sources of pollution. The traut stream, which maintains high densities of traut and is in very good ecological condition, must be managed with special consideration, where raad construction and other activities must be thoraughly assessed with risk analyses, strict mass management and sediment control. Overall, the report shows that the ecological water quality is good to very good, and fish stocks in most of the lakes have good spawning and grawth conditions, with same regional differences related to habitat use and grawth conditions. The management should adopt a holistic, catchment-oriented approach to new interventions in the area, with a fous on minimising the impact on water bodies and ensuring sustainable use of resources. More detailed suggestions are mentioned in the report, which forms a basis for further monitoring and enviranmental measures to preserve biodiversity and , maintain the good ecological status of the entire area.
