Sustainability labels serve as crucial instruments facilitating the presentation of credible product attributes, enabling consumers to assess various aspects of sustainability in their purchasing decisions. This study aims to evaluate consumers’ preferences and willingness to pay for sustainable certifications, specifically Fairtrade and UTZ certification, within the coffee sector in Spain. Employing the choice experiment approach, an online survey involving 547 Spanish consumers was conducted, and a conditional logit model was estimated. The findings indicate that consumers exhibit positive utility towards both sustainability labels examined. Furthermore, the results reveal that consumers are willing to pay a premium of EUR 1.481 per 250 g for the Fairtrade label and EUR 1.379 per 250 g for the UTZ label. The proposed model offers an initial insight into willingness to pay for sustainable coffee in Spain. These results furnish valuable insights for the coffee sector in crafting effective marketing strategies to bolster initiatives promoting sustainable production practices and expanding market access for certified coffee products.

Aquaculture in the Arab region has grown rapidly over the past two decades. Nonetheless, its sustainability faces challenges due to reliance on costly imported protein sources. Insect meals have emerged as potential alternatives, yet the region’s willingness to accept (WTA) insect-based aquafeeds remains largely unexplored. This study surveyed consumers ( ) and industry stakeholders ( ) across five Arab countries, examining WTA in relation to sociodemographic, cultural, religious, and economic factors, while drawing insights from the European experience. WTA levels varied, with 61% of consumers and 80% of stakeholders expressing WTA. Despite these relatively high rates, knowledge regarding insect meals and WTA remained limited, with 14% of consumers and 60% of stakeholders demonstrating adequate understanding. For both consumers and stakeholders, statistically significant predictors of willingness to adopt insect-based aquafeeds included age, knowledge, and exposure to relevant information. Consumers were influenced by income, fish species consumed, and emotional barriers, while stakeholders were affected by price sensitivity. Cultural and religious beliefs, environmental awareness, and health and safety were not significant determinants. Current WTA levels indicate that the Arab market is well-positioned to adopt insect-based aquafeeds. Strengthening regulatory frameworks, introducing Halal certification, enhancing institutional arrangements, promoting participatory stakeholder governance, and improving communication could further increase WTA. Simultaneously, scaling up production, investing in R&D, and reducing insect meal production costs would support adoption. Together, these measures can accelerate the wider use of insect-based aquafeeds and contribute to sustainable aquaculture, resilience to climate-related risks, and improved food security across the Arab region.
