Prior research has shown a tendency for environmental problems to be rated as more severe at the global level than at the local level. The present article reports reanalyses of a large cross-cultural data set (Study 1: k = 22, N = 3,277) and new cross-cultural data (Study 2: k = 8, N = 1,131) examining the prevalence of this spatial bias in the rated severity of environmental problems along with analyses of individual and country-level predictors of this bias. Results from multilevel modeling analyses showed that spatial bias was greater for happier and younger individuals and for those from smaller communities. We interpret these results as evidence for self-serving and “place-serving” biases in which the bias tempers the severity of environmental problems in one’s local area. Considering the large cross-cultural evidence, we argue that spatial bias is a plausible candidate of a psychological universal identified by research in environmental psychology.

In accordance with cognitive dissonance theory, individuals generally avoid information that is not consistent with their cognitions, to avoid psychological discomfort associated with tensions arising from contradictory beliefs. Information avoidance may thus make risk communication less successful. To address this, we presented information on red meat risks to red meat consumers. To explore information exposure effects, attitudes toward red meat and perceived knowledge of red meat risks were measured before, immediately after, and two weeks after exposure. We expected information avoidance of red meat risks to be: positively related to (1) study discontentment; and (2) positive attitudes toward red meat; and negatively related to (3) information seeking on red meat risks; and (4) systematic and heuristic processing of information. In addition, following exposure to the risk information, we expected that (5) individuals who scored high in avoidance of red meat risks information to change their attitudes and perceived risk knowledge less than individuals who scored low in avoidance. Results were in line with the first three expectations. Support for the fourth was partial insofar as this was only confirmed regarding systematic processing. The final prediction was not confirmed; individuals who scored high in avoidance decreased the positivity of their attitudes and increased their perceived knowledge in a similar fashion to those who scored low in avoidance. These changes stood over the two-week follow-up period. Results are discussed in accordance with cognitive dissonance theory, with the possible use of suppression strategies, and with the corresponding implications for risk communication practice.

Coastal risk is already high in several parts of the world and is expected to be amplified by climate change, which makes it necessary to outline effective risk management strategies. Risk managers assume that increasing awareness of coastal risk is the key to public support and endorsement of risk management strategies – an assumption that underlies a common worldview on the public understanding of science, which has been named the deficit model. We argue that the effects of awareness are not as straightforward. In particular, awareness of coastal hazards might not lead to more technically accurate risk perceptions. Based on research on risk perception normalization, we explored the hypothesis that coastal risk awareness reduces coastal risk perception – in particular the perceived likelihood of occurrence of coastal hazards – through its effect on reliance on protective measures to prevent risk. Individuals can rely on protective measures, even when those are not effective, as a positive illusion to reduce risk perception. This effect might be stronger for higher probability hazards and for permanent residents of costal zones. Data from 410 individuals living in coastal zones corroborated most of our expectations. Global results demonstrated a risk normalization effect mediated by reliance on current measures. Additional analyses made clear that this effect occurred in 2 of the 5 high-probability hazards (flood and storm), and not in the low-probability hazard (tsunami). Normalization might be more likely among high-probability hazards which entail catastrophic and immediate impacts. This effect was also found among permanent residents, but not among temporary residents. Results imply that coastal risk management might benefit from (a) taking risk perception normalization effects into account, (b) tailoring strategies for permanent and temporary residents and (c) promoting a higher public engagement, which would facilitate a more adaptive and effective coping with coastal risk than the use of positive illusions.

The development of new biopolymer production technologies is becoming increasingly relevant for tackling the negative impact of linear plastics. Despite these potential benefits, their production and commercialization still face several obstacles that might hinder their widespread adoption. The present systematic review aimed to offer a thorough analysis of the multi-level supply-side barriers across researchers, policymakers, and industry professionals. Searches were performed in Web of Science, SCOPUS, PubMed, and IEEE Xplore between June and July 2023. Publications between 2019 and 2023 were considered for analysis (n = 176). Content was coded following a PICO structure and the results were reported following the PRISMA checklist. We found that technological and knowledge barriers were the most identified, followed by economic, regulatory, supply stability, and behavioral challenges. Moreover, we found that 82% of the documents identified more than one barrier, reflecting the complex interaction between the different challenges in the field. Fostering interdisciplinary collaboration, establishing clear regulatory frameworks, and enhancing communication strategies are relevant recommendations for overcoming these barriers. These findings draft a multifaceted roadmap of the key barriers in the commercialization of new, sustainable biopolymer production technologies, and carry significant implications for future research, policy development, and industry practices.

Stakeholder engagement in the processes of planning local adaptation to climate change faces many challenges. The goal of this work was to explore whether or not the intention of engaging could be understood (Study 1) and promoted (Study 2), by using an extension of the theory of planned behaviour. In Study 1, stakeholders from three European Mediterranean case studies were surveyed: Baixo Vouga Lagunar (Portugal), SCOT Provence Méditerranée (France), and the island of Crete (Greece) (N = 115). Stakeholders' intention of engaging was significantly predicted by subjective norm (which was predicted by injunctive normative beliefs towards policy-makers and stakeholders) and by perceived behavioural control (which was predicted by knowledge of policy and instruments). Study 2 was conducted in the Baixo Vouga Lagunar case study and consisted of a two-workshop intervention where issues on local and regional adaptation, policies, and engagement were presented and discussed. A within-participants comparison of initial survey results with results following the workshops (NT1 = 12, NT2 = 15, NT3 = 12) indicated that these were successful in increasing stakeholders' intention of engaging. This increase was paired with a) an increase in injunctive normative beliefs towards policy-makers and consequently in subjective norm, and to b) a decrease in perceived complexity of planning local adaptation and an increase in knowledge regarding adaptation to climate change.
