The increasing use of data-driven technologies in the agriculture industry introduced new opportunities for improving quality, efficiency, and sustainability in the agriculture sector. However, it has also brought major challenges to its agricultural data (agri-data) users, concerning trustworthiness, data sovereignty, and cybersecurity. This paper presents a conceptual framework that integrates these three pillars into a single approach to evaluate the reliability of agri-data sharing environments. The proposed framework offers guidelines for policymakers and agricultural businesses (agri-businesses) to deal with the complex digital agricultural landscape. It enables secure, sovereign, and trustworthy data sharing environments for all agri-data stakeholders, especially farmers. This paper also highlights a practical application through a real-world case study and recommends directions for future research.
