We used a survey to investigate the effects of personality, motives, and socioeconomics for drinking hard cider among 3,373 Norwegian respondents in 2023. Wine interest, cultural interest, having a high score on conspicuous attitude, or being female increased the predicted consumption frequencies of hard cider. Scoring high on the taste index, being a conscientious respondent, being older, higher educated, or believing religion is important reduced the predicted frequencies. The estimated effects were compared with the corresponding effects for red, white, and sparkling wines. Cultural interest and wine interest are the main motives for hard cider and all categories of wine.

This study investigates food neophobia as a potential barrier to the use of unconventional fertilizers, such as fish sludge and human waste, in food production. Using data from Norway, the study estimates consumers’ willingness to pay (WTP) for lettuce grown with these fertilizers. Results from the random effect interval regression model show that, on average, consumers are willing to pay 8 % more for conventional lettuce compared to lettuce grown with fish sludge and 13 % more for lettuce grown with human waste. However, between 40 % and 50 % of respondents accepted lettuce produced with unconventional fertilizers and were not willing to pay more for conventional lettuce compared to these alternatives. Key factors influencing WTP include gender, the presence of children in the household, and food neophobia. These findings suggest that food neophobia and socio-demographic factors can significantly impact consumer acceptance of sustainable agricultural practices. Targeted communication strategies focusing on food safety, environmental sustainability, and the benefits of nutrient recycling are needed to foster broader public acceptance and support for recycled waste in agriculture.

Boreal forests are important carbon sinks and host a diverse array of species that provide important ecosystem functions. Boreal forests have a long history of intensive forestry, in which even-aged management with clear-cutting has been the dominant harvesting practice for the past 50–80 years. As a second cycle of clear-cutting is emerging, there is an urgent need to examine the effects of repeated clear-cutting events on biodiversity. Clear-cutting has led to reduced numbers of old and large trees, decreased volumes of dead wood of varied decay stages and diameters, and altered physical and chemical compositions of soils. The old-growth boreal forest has been fragmented and considerably reduced. Here, we review short- and long-term (≥50 years) effects of clear-cutting on boreal forest biodiversity in four key substrates: living trees, dead wood, ground and soil. We then assess landscape-level changes (habitat fragmentation and edge effects) on this biodiversity. There is evidence for long-term community changes after clear-cutting for several taxa: epiphytic lichens; saproxylic fungi, bryophytes and insects; epigeic bryophytes; and soil snails, bacteria, and ectomycorrhizal fungi. Long-term declines in species richness were found for saproxylic fungi, bryophytes and true flies. However, for the majority of taxa, long-term effects of clear-cutting are not well understood. On the landscape level, reduced connectivity to old-growth forests has negative effects on several species of fungi, lichens, bryophytes and insects, notably among Red-Listed species. Furthermore, altered microclimate near clear-cut edges negatively affects epiphytic lichens and epigeic arthropods, implying complex effects of habitat fragmentation. Repeated cycles of clear-cutting might pose even stronger pressures on boreal forest biodiversity due to continued fragmentation of old-growth forests and accumulation of extinction debts. Examining the broad effects of forestry on biodiversity across the boreal biome is crucial: (i) to increase our knowledge of long-term and landscape-level effects of former clear-cutting; and (ii) to gain a better understanding of how forestry will affect biodiversity and, subsequently, ecosystem functioning, with repeated cycles of clear-cutting.
