Blockchain technology (BCT) is emerging as a key enabler of sustainability in various sectors, including agriculture. This study explores the impact of BCT adoption on sustainability within the Australian agriculture sector. Through a systematic literature review (SLR) of studies published between 2015 and 2021, ten key themes influencing BCT adoption were identified: transparency, traceability, contract exchange, transaction efficiency, trade finance management, quality control, real-time information dissemination, security, trust, and legislative frameworks. The findings suggest that BCT adoption in agriculture can lead to improved sustainability outcomes. By enhancing transparency and traceability, BCT enables stakeholders to track the provenance of products, reducing the risk of fraud and ensuring compliance with environmental standards. The automation and efficiency gains afforded by BCT streamline supply chain processes, reducing waste and resource consumption. BCT enhances trust among stakeholders, fostering collaboration and information sharing to address sustainability challenges. This study contributes to the literature by highlighting how BCT can drive sustainability in agriculture through improved transparency, efficiency, and collaboration.
