Abstract
The agricultural sector is increasingly recognized for its potential to mitigate climate change through carbon sequestration. However, the accurate and transparent validation of carbon credits generated by regenerative farming practices remains a significant challenge. This paper proposes a novel blockchain-enabled framework for automated lifecycle tracking and validation of carbon credits derived from regenerative agriculture. By leveraging distributed ledger technology, we aim to enhance the integrity, immutability, and transparency of carbon credit generation and trading processes. The methodology integrates Internet of Things (IoT) sensors for real-time data collection on soil health, crop yields, and farming inputs with blockchain technology to create an auditable and tamper-proof record of agricultural activities and their associated carbon sequestration outcomes. We detail the architecture of the proposed system, including data acquisition, on-chain storage, smart contract-based validation rules, and a tokenization mechanism for carbon credits. Preliminary analysis suggests that this approach can significantly reduce verification costs, prevent double-counting, and build greater trust among stakeholders in the carbon market. The findings highlight the potential of blockchain to revolutionize carbon accounting in agriculture, paving the way for more effective climate action and sustainable land management practices. This framework addresses critical issues of data integrity and validation, crucial for the nascent but growing field of agricultural carbon markets (Goswami, 2024; Abubakar & Ahamad, 2023).
