Housing affordability and climate sustainability are increasingly interlinked in Europe, as housing costs strain household budgets and the residential sector contributes significantly to greenhouse gas emissions. This study investigates Finnish public perceptions of decarbonization housing policies, particularly views on financial support for the transition to low-carbon housing. Using nationally representative survey data from 2022, combined with housing registry and price data, we analyze how both objective and subjective indicators of energy poverty are linked with support for public funding. The findings demonstrate strong public support, particularly among women, urban residents, and those using oil heating. Objective energy poverty correlates positively with policy support, and subjective economic well-being mediates this relationship. These findings contribute to the growing literature on housing, energy poverty, and climate policy acceptance, underscoring the importance of addressing social vulnerabilities to secure equitable and widely supported low-carbon housing transitions.

Background and aims: European wheat production faces the challenge of maintaining yields while reducing environmental impacts from agrochemicals. Organic farming is often considered a sustainable alternative to promote soil health and reduce chemical inputs. This study assessed nutrient status in wheat soils across nine European pedoclimatic zones, comparing conventional and organic systems and evaluating management practices such as crop rotation, tillage and fertilization type. Methods: A total of 188 soils were analyzed for macro- and micronutrients, and wheat yield data were evaluated in relation to soil nutrients, climate, wheat type (winter- vs. spring-sown), and management using correlation, random forest, and regression analyses. Results: Soils showed excess P, K, Mg, Cu, Fe, Mn, and Zn, but S and B deficiencies. Organic systems increased total N, while conventional farming enhanced nitrate, sulfate, and boron. Wheat yield was primarily driven by temperature, precipitation, wheat type (winter- vs. spring-sown), and farming system, with additional contributions from fertilization and nutrients (particularly exchangeable Ca, Fe, Mn, and Zn). On average, organic yields were 37% significantly lower than conventional, but these differences were smaller in Mediterranean zones due to reduced pest pressure and improved water retention and infiltration. Practices such as crop rotation, residue incorporation, and reduced tillage positively influenced yield. Conclusion: Organic farming supports soil health and sustainable use of resources, but may reduce wheat yield in northern and central European pedoclimatic zones. Tailored nutrient management combined with agronomic practices can enhance productivity while minimizing environmental impacts, especially in climate-stressed regions.

Soil electrical conductivity (EC) and aggregate-size distribution are critical indicators of soil salinity risk, structural integrity, and overall soil health. We assessed the status of these properties in 188 wheat plots across nine European pedoclimatic zones to quantify the influence of climate and agricultural management. Most soils (~88%) were non-saline, 9% slightly saline, and 3% moderately saline, with the highest salinity in Mediterranean regions. EC was generally lower under organic management, reflecting higher soil organic carbon, improved porosity, and enhanced cation retention. Soils were dominated by small macroaggregates (250–2000 µm) and large microaggregates (53–250 µm), together accounting for an average of 73% of total aggregates. Climate was the primary determinant of both EC and aggregate distribution, with drier and warmer conditions promoting salinization and smaller aggregate sizes, whereas wetter conditions favored macroaggregate formation. Agricultural management had a secondary but context-dependent effect, particularly on soil aggregation, with organic farming, integrated organomineral fertilization, crop residue incorporation, and legume rotations enhancing macroaggregate formation, especially in low-SOC soils. These results indicate that pedoclimatic conditions largely shape soil salinity and structure, but adopting targeted, site-specific management practices can sustain soil health and mitigate risks related to salinity and structure, particularly under projected climate change.
Improved subsurface drainage increased small grain cereal yield but not the soil carbon stock of a boreal clay soil

Removal of excess water by soil drainage is a prerequisite of proper yields in boreal agriculture. A functioning drainage system enables farming operations, maintains yields and improves the environmental performance of a field plot. As carbon input to soils in crop residues increases with the yield, increased crop production might benefit the carbon balance of the soil. We document the effects of drainage renovation on the yield and crop residue production of spring cereals at a long-term experimental site on Protovertic luvisol in south-western Finland and discuss their relevance for soil carbon sequestration. The yield and amount of crop residues were monitored continuously before (1985–1990) and after (1992–1997) a drainage renovation. The cereal yields almost doubled, reaching the current average yields, and the amount of crop residue increased by 30% after the improvement of the drainage system. This was, however, not significantly reflected in the soil carbon stock. Drainage renovation can be considered sustainable intensification that provides long-term benefits for crop production, but carbon sequestration likely requires more carbon input than is available in the cereal straw.
Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine-scale GPS-based habitat selection data with broader-scale dietary information from stable isotope analysis (δ13C, δ15N) of hairs in semi-domesticated reindeer Rangifer tarandus tarandus. Thresholds introduced within this framework detect seasonal shifts in habitat and diet selection and classify foraging strategies along a specialist–generalist continuum. Despite individual variability, most individuals exhibited pronounced seasonal changes between spring/early summer (SES) and late summer/autumn (LSA), consistent with generalist foraging strategies. Habitat selection models revealed reduced avoidance of rugged terrain and increased use of mires and bogs from SES to LSA. Concurrently, isotopic enrichment and niche expansion reflected a dietary shift from δ15N- and δ13C-depleted plants (e.g. lichens, shrubs, deciduous vegetation) to more enriched forage types such as sedges, grasses, horsetails, and mushrooms. We assessed whether individual-level shifts in diet and habitat use were linked and found an inverse correlation between the shifts in terrain ruggedness avoidance and dietary change in approximately 67% of individuals, suggesting that behavioural flexibility facilitates seasonal transitions. By integrating spatial and isotopic data, this study overcomes the limitations of single-method approaches and provides a more nuanced understanding of the seasonal foraging dynamics of a keystone Arctic and boreal ungulate. The findings highlight the plasticity of reindeer foraging within a variable environment and suggest a capacity to respond to environmental changes. This framework also offers broader applications for investigating behavioural responses and ecological strategies in other herbivores facing climate-driven habitat shifts.
