Food security is an urgent global challenge, intensified by population growth, climate change, and resource limitations. Circular bioeconomy, with its focus on sustainability and efficiency, offers a novel paradigm to address these challenges. By emphasizing sustainable practices, waste reduction, and the integration of biological processes, circular bioeconomy emerges as a transformative framework to ensure a resilient and secure food future. This manuscript aims to describe the challenges facing food security and provide a brief overview of the relationship between the bioeconomy and the agricultural sector, with a focus on the bioeconomy status in Latin America and the Caribbean.
