    Valorizing meat by-products for human consumption: understanding consumer attitude formation processes
    (Frontiers Media SA, 2023-01-01)
    Georgia Lavranou  
    Introduction A considerable body of research has identified that meat by-products contain significant amounts of high-quality protein, which when properly extracted can lead to valuable opportunities for the food industry. However, the market success of food products containing protein extracted from meat byproducts is subject to consumer acceptance. This study explores Irish consumers’ attitudes toward hypothetical food products containing protein derived from beef offal sources. Methods A nationally representative survey (n = 953) was undertaken to investigate what attitude processes, that is intuitive and/or deliberative, dominate attitude formation toward food products containing beef offal-derived protein, while accounting for the effects of product familiarity and information provision. Using a 2 x 3 between-subject design, study participants were randomly assigned to one of the 6 study conditions. Participants were exposed to Affect Misattribution Procedure (AMP) tasks which measured their intuitive evaluations, followed by a number of questions that measured deliberative evaluation, attitude ambivalence, attitudes and acceptability toward the food products containing protein extracted from beef offal. Results The study reveals that consumers’ intuitive and deliberative evaluations worked in the same direction, predicting overall attitudes toward these products; however, deliberative evaluation was found to be a better predictor of consumers’ attitudesthan intuitive evaluation. Moreover, intuitive evaluations do not influence deliberative evaluations, suggesting that information provision that prompts deliberative evaluations could lead to the formation of more considered and stable attitudes. Familiarity influences acceptance: these findings suggest that the potential impact of a lack of familiarity with the ingredient is offset by familiarity with the carrier products. Consumers who received benefit information about the health and environmental consequences of consuming food products containing protein extracted from beef offal expressed a more positive deliberative attitude toward these products. However, interestingly, the provision of benefit- and risk-orientated information at the same time at the same time also had a positive effect on deliberative evaluations. Discussion The findings have implications for new product development, and more generally for strategies that seek to promote sustainable food production and consumption.

    Nostradamus focuses on addressing the critical challenges of food security, sustainability, and agricultural resilience in the European Union (EU) by leveraging digital solutions for resilient agriculture and independence from agrochemical inputs. This Horizon Europe project aligns with the EU Green Deal, Common Agricultural Policy, forthcoming Soil Monitoring Law, and EU Data Strategy, among others, promoting open-source data ecosystems and tools to enhance agricultural resilience and sustainability. Central to the project is developing a Data Ecosystem comprising five national Data Cubes spanning Cyprus, Germany, Serbia, Slovenia, and Switzerland and a Catalog for geospatial and non-geospatial datasets. Interconnectedly, the Data Ecosystem serves as a one-stop-shop for data aggregation by integrating Earth Observation, IoT, socio-economic, and other relevant datasets, establishing robust pipelines for collecting, processing, and analysing data from multiple sources. By providing farmers, policymakers, researchers, and industry with comprehensive, accessible, and interoperable digital solutions, the Nostradamus project will empower informed decision-making and policy-shaping to enhance the agricultural sector's competitiveness and productivity while minimizing environmental impact. The project’s overarching objectives are: (1) to serve as a data-driven backbone for the EU’s food security and independence, and (2) to enable the development of scalable, open-source digital applications through Open Calls tailored to address the complexities of modern agriculture. These applications will tackle pressing challenges such as drought monitoring, crop yield prediction, soil fertility management, and sustainable pest control. By employing machine learning, these tools support stakeholders in optimizing farming practices and resource allocation, reducing dependency on agrochemical inputs, and ensuring resilience against disruptions. Nostradamus adopts a gender-sensitive multi-actor approach, fostering collaboration among diverse stakeholders. This inclusive strategy ensures solutions are co-created and validated across various biogeographical and socio-economic contexts. The project’s five demonstration sites, located in the distinct biogeoclimatic regions, act as hubs for testing and showcasing innovations, enabling the transfer of knowledge and best practices across the EU. Recognizing the challenges posed by digital inequity, particularly in regions with limited connectivity, Nostradamus integrates cloud, edge, and mixed solutions to ensure accessibility and scalability. Additionally, the project provides a suite of ready-to-use templates that facilitate the seamless development and integration of modular digital applications for solving specific challenges while benefiting from standardized, interoperable foundations. Through tailored capacity-building, the project empowers end-users to utilize digital tools and fully adopt data-driven decision-making practices. The project also emphasizes the importance of data interoperability, switchability, and transparency, laying the foundation for the future evolution of agriculture in the EU. Beyond its technical contributions and support for EU policy frameworks and engaged actors, including AKIS platforms, Nostradamus actively supports upscaling the impact of ongoing EU projects by addressing critical gaps in data requirements and consolidation. By bridging technological innovation with stakeholder-driven development, Nostradamus represents a paradigm shift in the EU's agricultural digital transformation. Its outputs ensure that the sector remains resilient, competitive, and aligned with long-term sustainability goals. The project exemplifies how data-driven solutions can create a more secure, sustainable, and equitable future for the EU agricultural sector, setting a benchmark for global initiatives in agricultural innovation.

    To work towards climate neutrality, the European Union (EU) has established a new target within the revised Regulation on land, land use change and forestry (LULUCF) aiming to achieve a net removal of 310 million tons of CO2 equivalent by 2030 through land-based actions. The LandShift project represents a transformative approach to land-use planning and management, addressing the complex challenges of climate change, biodiversity loss, and unsustainable practices in various terrestrial ecosystems, including forests, farmlands, peatlands, and wetlands. Aligning with the EU Green Deal, forthcoming Soil Monitoring Law, and New European Bauhaus (NEB) principles, among other initiatives, LandShift aims to achieve a climate-neutral land-use sector through the establishment of five interconnected Living Spaces (LSs) located in France, Greece, Italy, Poland, and Ukraine. These regions will serve as hubs for co-creation, innovation, and co-governance of sustainable solutions that integrate ecological, social, and economic dimensions. At its core, LandShift leverages digital technologies, including Earth Observation and Artificial Intelligence to optimize land-use strategies and enhance climate actions by providing actionable insights into carbon sequestration, ecosystem resilience, and biogenic emissions through a holistic approach. Additionally, the LandShift data ecosystem, built around five regional Data Cubes, acts as a comprehensive resource for stakeholders, offering harmonized data to support informed decision-making. By integrating the Living Earth framework and Multi-Criteria Decision Analysis, LandShift systematically evaluates trade-offs among climate mitigation, food and biomass production, biodiversity conservation, and socio-economic objectives. The project’s innovative approach integrates Nature-Based Solutions (NBS) with NEB principles, emphasizing aesthetic value, inclusivity, and sustainability to facilitate the operationalization of regional strategies. Through workshops, co-creation activities, and a digital library of NEB-aligned NBS, LandShift promotes practices that enhance ecological balance while effectively bridging the gap between top-down policies and on-the-ground realities. LandShift also addresses the urgent need for robust monitoring, reporting, and verification frameworks, which offer the capacity to measure the impact of implemented solutions while integrating environmental considerations with financial incentives, such as Environmental Impact Bonds. A distinguishing feature of LandShift is its emphasis on inclusive collaboration among all key stakeholders from the Quintuple Innovation Helix framework through a multi-actor approach. Policy and Community Labs will facilitate co-design processes, ensuring that solutions are context-specific and aligned with the unique needs and priorities of each LS while fostering co-ownership through crowd-sourcing and crowd-funding mechanisms. The project also examines dietary preferences while implementing efforts to transform Data Cubes and Living Earths into Knowledge Cubes. Tailored capacity-building further empower stakeholders to adopt and co-implement these solutions effectively, ensuring that the LSs become Lighthouses of regionally socio-economic and environmentally responsible strategies for achieving a climate-neutral land-use sector. LandShift integrates with over 15 EU strategies, leveraging synergies with complementary programs to enhance scalability, promote transdisciplinary collaboration, and strengthen contributions to overarching EU objectives. Its holistic, data-driven approach establishes a benchmark for sustainable land management, offering replicable and scalable solutions across Europe. By bridging the gap between policy and practice, LandShift envisions resilient, sustainable, and inclusive landscapes, transforming land-use planning and management to deliver enduring benefits for communities and ecosystems.
