<p>This paper examines farmer data sovereignty and valuation approaches as critical elements for advancing sustainable agriculture. It analyses technological, educational, legal, economic, and methodological barriers to implementation, proposing a holistic approach to overcome these challenges. The study introduces an innovative data valuation model incorporating investment costs, potential commercial usage, and ecosystem services value, along with a framework for integrating this value into agricultural accounting practices. By exploring successful case studies, emerging technologies, and gender equity considerations, the paper offers insights for policymakers and stakeholders. It emphasises the need for collaborative efforts between farmers, researchers, policymakers, and technology providers to create a more sustainable, resilient, and equitable agricultural system. The study concludes by outlining future research directions to further develop and refine these approaches in the context of evolving agricultural practices and technologies.</p>
