 Smart and sustainable agricultural practices require a greater degree of complexity compared to other industries due to the unpredictable nature of production factors. Studies have suggested that technologies like blockchain can be used to achieve these goals. This systematic review examined the barriers and enablers of blockchain adoption for smart and sustainable agriculture. The findings suggest that while blockchain has potential to facilitate smart and sustainable agriculture, it faces challenges related to lack of global standards, industry-level best practices and policies, and a lack of stakeholder collaboration. Recommendations and implications are provided to address these knowledge gaps. This article was authored by Gopi Krishna, Akela, Santoso, Weboo, Srimanore and Agrandi, and others.
