To address climate change, reducing food loss along the production and supply chain is a global priority. Addressing this challenge requires a shift in agrifood systems toward greater sustainability, in which new technologies and novel foods appear as promising strategies. Among emerging novel foods, 3D-printed foods are an interesting new food technology for food loss reduction, resource optimization, and by-product valorization. However, to reach market success, it needs consumer acceptance, a topic far unexplored, particularly in the Italian context. To fill the literature gap, this article investigates Italian consumers’ intention toward 3D-printed savory snacks using an extended Theory of Planned Behavior, based upon the relevant literature. Survey data were collected, and partial least squares structural equation modeling was performed to test research hypotheses. Results show that attitude and subjective norms are the strongest predictors of purchase intention. In addition, perceived usefulness is shown to be a powerful construct, positively impacting attitude and subjective norms, while self-identity as a green consumer reinforces perceptions of the benefits of 3D-printed foods. Sensory appeal impacts consumer attitude. These insights have practical policy and micro-level applications, suggesting tailored strategies, educational campaigns, and supportive policies and marketing campaigns for fostering acceptance of 3D printing in the agrifood sector.

Olive cultivation represents a key pillar of rural economies and cultural heritage in Mediterranean regions, including western Greece. Despite its socio-economic importance, the sector faces increasing pressures from climate change, market volatility, and technological transformation, while progress toward environmentally sustainable production remains uneven. This study investigates how olive farmers’ perceptions of carbon footprint and climate risks are influenced by their demographic characteristics. Primary data were collected through 402 structured questionnaires distributed to olive producers in the Aetolia–Acarnania region. The sample was designed to represent farmers directly engaged in olive production, ensuring the relevance and reliability of the collected data. The findings, based on descriptive statistics, reveal significant heterogeneity in producers’ perceptions of climate risks and their capacity to respond through sustainable practices. Demographic characteristics appear to play an important role in shaping awareness of carbon footprint and the potential adoption of environmentally responsible farming strategies. These results suggest that sustainability transitions in perennial cropping systems depend not only on technological availability but also on social, informational, and institutional capacities. Strengthening agricultural advisory services, farmer training, and climate adaptation strategies may therefore support the adoption of climate-smart practices in olive cultivation. Furthermore, cooperation and value-chain integration are identified as potentially important mechanisms for facilitating knowledge transfer and supporting the adoption of sustainable practices (e.g., efficient irrigation and optimized input use). However, their contribution to environmental performance and greenhouse gas mitigation cannot be directly inferred from the present perception-based analysis and should be examined in future research using appropriate quantitative or environmental assessment frameworks.

Mediterranean forests are increasingly exposed to climate-related risks, including large wildfires, prolonged droughts and rural abandonment, making sustainable forest management (SFM) a key element for climate adaptation and territorial resilience. However, despite its recognised importance, the social acceptance of SFM remains insufficiently understood, particularly in relation to how public perceptions are shaped by media narratives and information ecosystems. This study addresses this gap by analysing the relationship between media framing and social acceptance of SFM in a Mediterranean context. A mixed-methods approach was applied in the Valencian region (Spain), combining (i) a systematic analysis of conventional and digital media, (ii) a system mapping exercise to identify dominant narratives and communication dynamics, and (iii) a population survey (n = 1070) focused on perceptions of forests, climate change and forest management. The results reveal a high level of environmental concern and climate awareness, coexisting with limited knowledge of SFM and simplified or distorted perceptions of forest dynamics. Media coverage is predominantly reactive and event-driven, strongly focused on wildfire events, while preventive and adaptive forest management practices remain largely invisible. In this context, support for SFM increases significantly when management practices are clearly explained and contextualised, indicating that resistance is more closely related to communication gaps than to ideological opposition. These findings highlight the critical role of media framing and communication processes in shaping the social acceptance of SFM. The study contributes to the literature by integrating media analysis and social perception within a forest governance perspective, and provides empirical insights to support more effective communication strategies and policy design in Mediterranean regions facing increasing climate pressures.

Marine turtles are key species for the stability of coastal and oceanic ecosystems; however, their conservation faces increasing pressures derived from climate change and anthropogenic activities. This study analyzes the perception of the academic and scientific community in biology, environmental sciences, and marine sciences regarding marine turtle conservation along the coast of Sinaloa, Mexico. A quantitative cross-sectional survey-based study with an exploratory approach was employed, using a Likert-scale questionnaire administered to 358 participants. The instrument demonstrated adequate internal consistency (α = 0.836; ω = 0.827). An exploratory factor analysis (EFA) using principal component extraction identified four components explaining 55.51% of the total variance, corresponding to four dimensions: (1) commitment to conservation, (2) environmental and climatic impacts on reproductive processes, (3) key factors and threats in the reproductive cycle, and (4) conservation practices and knowledge. Results suggest a general tendency toward agreement on the ecological importance of marine turtles and the threats affecting their reproductive success, particularly climate-related and habitat degradation factors. However, greater variability was observed in perceptions related to applied practices and technical knowledge, indicating differences in perceptions related to the implementation of conservation strategies. These findings suggest the potential relevance of strengthening applied training, interdisciplinary collaboration, and knowledge transfer mechanisms to enhance the effectiveness of conservation initiatives in priority nesting areas of Sinaloa.

Like other agricultural products, food legumes production faces uncertainty risks stemming from climate change, which may affect yields and consequently impact farmers’ livelihoods. Agricultural insurance serves as one of the climate change adaptation measures available to farmers, helping mitigate the impacts of climate change on agricultural production and livelihoods. While considerable attention has been paid to climate change adaptation through production-side measures, comparatively fewer micro level studies examine insurance adoption as an adaptive response, particularly among food legume farmers. Based on a survey of 460 food legume farmers in Baicheng City, Jilin Province of China, this study employs a binary probit regression model to analyze the relationship between climate change perceptions and farmers’ adoption of agricultural insurance as an adaptation measure. Farmers’ climate change perception is measured through four indicators: perceived changes in average annual temperature, precipitation, drought severity, and frost severity over the past five years. Robustness tests are conducted by using a replacement econometric model, altering the climate change perception variable, and implementing sample restriction. Results indicate that food legume farmers’ perceptions of climate change exhibits significant correlation with their agricultural insurance purchasing behavior. Farmers who perceive lower temperatures and more severe frosts are more inclined to purchase agricultural insurance. Participation in food legume production cooperatives and prior experience with yield reductions exert significant positive correlation with insurance purchase decisions. Therefore, enhancing targeted outreach and education, leveraging the role of cooperatives in insurance promotion, and implementing differentiated insurance promotion based on disaster experiences hold positive implications for reducing farmers’ exposure to climate change risks. The findings further offer valuable insights into climate adaptation policy in other drought-prone, legume-growing regions. Full article

The agricultural sector faces increasing vulnerability to climate change, necessitating effective adaptation measures to maintain productivity and enhance system resilience. Despite this critical need, limited studies explore the factors influencing farmers’ adaptive responses within specific climatic zones. This study aimed to identify adaptation measures essential for agricultural sustainability in the three purposively selected Grama Niladari divisions (GNDs) known for their diverse crop varieties in the Maho Agrarian Zone, a region characterised by the Maha (Northeast Monsoon) and Yala (Southwest Monsoon) agricultural seasons. A mixed-methods descriptive research design, integrating quantitative surveys and qualitative focus group data, was employed. The findings reveal a highly experienced farming community: 34.9% of farmers have over 30 years of farming experience. A total of 96.7% of farmers reported noticing changes, including a shift in seasons (over 80%) and unpredictable rainfall patterns (53%). A vast majority (62.8%) of farmers lack access to agricultural insurance, leaving them financially exposed to crop losses. Furthermore, while younger and middle-aged groups demonstrated the highest awareness of climate-smart agriculture (CSA), there is a strong, consistent perception across all age groups that government and associated institutions are not providing sufficient support for adaptation efforts. The results offer actionable recommendations for empowering local planning authorities, optimising climate communication strategies, and prioritising the development of practical CSA training modules, ultimately synthesising local knowledge with expert insight to support global resilience-building initiatives.

As the world progresses towards more sustainable food systems, an increasing number of individuals are inclined to reduce meat consumption and transition to plant-based protein sources. Given the implications of climate change and escalating public health issues, plant-based protein sources appear to be a viable alternative; yet, this transition will be challenging to implement. Legumes, cereals, oilseeds, microalgae, and mycoprotein constitute the primary sources of plant-derived protein. Each possesses distinct functional attributes; yet, they also exhibit certain nutritional constraints. The restrictions mostly pertain to the composition of essential amino acids and the body’s efficacy in utilizing micronutrients such as iron, zinc, and vitamin B₁₂. From an ecological perspective, plant-based proteins often exert a significantly lesser impact on the environment compared to conventional meat. This reduces greenhouse gas emissions and optimizes resource utilization. Recent technological advancements, including fermentation methods, shear cell structuring, and high-moisture extrusion, have significantly improved the texture and flavor of plant-based products. However, consumer perceptions of the sensory attributes of these products significantly influence their acceptance. Current research priorities include improving protein digestibility, mitigating antinutritional factors, reducing salt content, and generating robust long-term data on health effects/health benefits. Ultimately, replacing meat with plant-based proteins involves not only scientific and nutritional considerations but also requires significant cultural and societal transformations to establish a more balanced and sustainable food system.

This exploratory study explores the preparedness and response strategies of tourism businesses to climate change through an in-depth qualitative analysis. Using open-ended questionnaires, we collected detailed narratives from a diverse range of tourism businesses, allowing respondents to express their perceptions, strategies and challenges in their own words. Thematic analysis of the data revealed a wide variation in how businesses understand and respond to climate risks. While most participants acknowledged climate change as a critical issue, many reported significant barriers, such as financial constraints and lack of expertise, which hindered their ability to implement meaningful strategies. Key themes that emerged from the data include the role of external support in overcoming financial and technical challenges, the diversity of mitigation strategies adopted and the gap between climate awareness and practical action. This study pinpoints the need for tailored interventions to support small- and medium-sized enterprises (SMEs) in the tourism sector, highlighting the complexity of translating climate change awareness into tangible business practices. The findings contribute to the growing discourse on sustainable tourism by offering an understanding of the challenges and opportunities that businesses face in addressing climate change.

The energy transition of small and medium-sized enterprises (SMEs) is an important element in achieving climate and energy goals, but its pace and scope remain varied. Previous studies have focused mainly on regulatory pressure, energy costs and financial barriers, while the importance of market factors has been analysed relatively rarely. The aim of this article is to assess consumer expectations perceived by enterprises as a factor that influences SMEs’ energy transition strategies. While the approach demonstrated by previous authors concentrated mostly on energy transition as a policy issue or an adjustment to legal changes, the originality and contribution of this paper lies in approaching this problem as one of a strategic adjustment to customers’ changing expectations. The study is based on a CATI survey of 417 Polish SMEs, predominantly micro- and small enterprises. The study covers the perception of customer expectations regarding energy efficiency, the use of renewable energy sources (RES) and environmental communication tools. Relationships were identified between perceived market signals and the energy-related actions of enterprises. The results indicate that SMEs perceive consumer expectations primarily as specific and quantifiable energy measures, such as reducing energy consumption and implementing renewable energy sources, while attaching less importance to formal reporting and certification tools. The energy transition is selective and incremental, focusing on solutions with low barriers to entry and short payback periods. From an energy policy perspective, the results suggest a need to design support instruments that are better aligned with how SMEs interpret market expectations. Full article

We argue that mainstreaming Nature-based Solutions (NbS) requires alignment of diverse value systems and integrated, cross-sectoral collaboration, and we present the necessary conditions for increasing practical implementation. NbS are increasingly recognised as effective strategies to protect critical infrastructures against climate change impacts while enhancing them by delivering ecological, social, and economic benefits. Despite growing policy support, the integration of NbS into mainstream infrastructure planning remains limited due to siloed responsibilities and decision making, entrenched institutional structures that favour grey infrastructure, and challenges in balancing short-term risks with long-term value. We examine if and how NbS mainstreaming in the infrastructure sector could be enabled. Building on insights into infrastructure governance and innovation mainstreaming, we explore perceptions and engagement with NbS and opportunities for strengthening co-governance and collaborative decision making in the Dutch infrastructure domain. A critical insight is that NbS must be understood as part of a broader socio-ecological–technical system rather than isolated interventions. This results in requirements for more integrated approaches to governance and planning as well as assessment. Asset managers in particular could play a pivotal role by adopting holistic performance assessments that consider co-benefits and trade-offs. Full article

Global climate change poses increasing challenges to agricultural production and global food security by intensifying temperature and precipitation variability and increasing the frequency of extreme weather events. While several studies have examined farmers’ perceptions of climate change in the United States, limited empirical evidence exists for the Delaware, Maryland, and Virginia (Delmarva) Peninsula. This study assessed farmers’ perceptions of climate change in the Delmarva region and identified key factors influencing these perceptions, as well as adaptation strategies employed to address climate-related risks. Primary data were collected through a structured survey administered to farmers across the Delmarva Peninsula, while secondary data consisted of historical temperature and precipitation records obtained from meteorological stations in the region. Descriptive statistics were used to summarize farmer perceptions and adaptation practices, and a logit regression model was applied to examine socioeconomic and experiential factors influencing perceptions of climate change. Analysis of climate data revealed notable variability in temperature and rainfall patterns, with the warmest temperatures occurring during June, July, and August and peak rainfall generally observed between May and September. Survey results showed that a large majority of respondents (88.2%) perceived that climate change is occurring. Logit model results indicated that farmers’ age, education level, acceptance of climate change adaptation practices, and observed changes in climate over the past 5–10 years positively influenced perceptions of climate change. Adaptation strategies included selective crop choices, avoiding cultivation in flood-prone areas, adoption of soil conservation practices, and the use of crop insurance. Full article

Population aging and climate change are two long-term processes that increasingly intersect, yet their interrelationship remains insufficiently explored in Southeast Europe. This article examines how adults aged 50+ in Serbia and Bulgaria understand, perceive, and respond to climate risks, with the aim of identifying age-specific vulnerabilities as well as opportunities for climate action. We administered the ClimateMind50+ questionnaire to purposive national samples comprising 309 respondents in Serbia (CAPI, 82 municipalities) and 155 respondents in Bulgaria (CAWI, 74 municipalities). Socio-demographic differences were analyzed using descriptive statistics and χ² tests. The findings indicate moderate levels of self-assessed climate literacy, strong concern about the impacts of climate change on future generations, and heightened anxiety regarding extreme heat and prolonged dry periods. During climate-related emergencies, respondents rely predominantly on family networks rather than local institutions, and overall preparedness for extreme events remains limited. Adaptive and pro-environmental behaviors are modest and vary by gender, education level, and type of settlement. Population aging interacts with socio-economic vulnerability, energy poverty, regional decline, and governance constraints, shaping both exposure to climate risks and the capacity for behavioral adaptation. Climate strategies in both countries should therefore become more age-inclusive and socially responsive, recognizing older adults not only as a vulnerable group but also as active contributors to resilience.

Solar Radiation Modification (SRM) is increasingly discussed as a potential supplement to climate-change mitigation, yet public and stakeholder judgments remain sensitive to knowledge, framing, and perceived risks. We examined how a structured university classroom module on SRM reshaped student perceptions using a matched pre–post survey design. Participants were students enrolled in an English-taught global climate change course (N = 106); 103 students provided valid matched responses after applying pre-specified exclusion rules. Self-rated SRM knowledge increased substantially after the module (mean change +0.47 on a 1–3 scale; Wilcoxon signed-rank p (Holm-adjusted) < 1 × 10⁻⁷; Cohen’s dz = 0.67). Support for SRM research remained moderately positive but did not increase (pre mean 3.76 to post mean 3.54 on a 1–5 scale). In contrast, support for stratospheric aerosol injection (SAI) deployment declined (pre mean 3.42 to post mean 2.95; p (Holm-adjusted) = 0.0084; dz = −0.33), and preferences shifted away from prioritizing climate intervention toward low-carbon development (mean change −0.68 on a 1–5 priority scale; p (Holm-adjusted) = 0.0001; dz = −0.45). Post-lecture models indicated that perceived benefits versus risks was the most consistent correlate of support across outcomes. Open-ended responses most frequently emphasized feasibility, unintended consequences, governance, and moral hazard. Overall, students largely endorsed SRM research as valuable while becoming more cautious about deployment and political prioritization, suggesting that balanced, structured instruction can sharpen sensitivity to evidence, uncertainty, and potential trade-offs that students also weighed in the survey.

Climate change poses increasing challenges to agricultural systems in vulnerable territories, where climate variability, ecosystem degradation, and governance constraints interact to shape farmers’ management decisions. Understanding how institutional and social factors influence adaptive responses is therefore critical. This study examines how trust in public environmental agencies shapes small farmers’ willingness to adopt climate change adaptation practices in the highly vulnerable district of Alhué, central Chile. A structured questionnaire was administered to small farmers to assess willingness to adopt adaptive practices and levels of trust in public environmental agencies. Multivariate models revealed a non-linear, U-shaped relationship between trust in agencies and willingness to adopt adaptive practices: willingness was lowest at intermediate levels of trust and higher among farmers reporting either low or high trust in environmental agencies. This pattern remains robust after controlling for socioeconomic characteristics and climate change perceptions. The results highlight how heterogeneous trust dynamics condition adaptive behavior, suggesting that both barriers and strong institutional confidence may influence adaptation through different mechanisms. Overall, the findings underscore the importance of socially legitimate and context-sensitive governance arrangements for fostering climate change adaptation in vulnerable rural territories.
