How blockchain is used in agriculture supply chain?

Published on May 2, 2024

 Agriculture isn’t simply a sector; it serves as the foundation of the worldwide food supply network, playing a major role in economies, communities, and ecosystems globally. With the increasing world population, the demands on agriculture are growing, requiring advancements for improved effectiveness, visibility, and security. Blockchain technology is best known for its connection to digital currencies, and it is playing a crucial role in improving transparency and productivity in the agricultural industry supply chains. This analysis seeks to clarify the transformative impact of blockchain on agricultural logistics, exploring its uses and examining the advantages and current obstacles.

Blockchain Technology

Decoding Blockchain

At its core, blockchain acts as a formidable system for recording information, making it exceedingly difficult, if not impossible, to change, compromise, or manipulate. It functions as a digital ledger of transactions, replicated and spread across a vast network of computers within the blockchain. Each block in this chain contains a sequence of transactions, with every new transaction recorded across every participant’s ledger, representing what is known as Distributed Ledger Technology (DLT).

Fundamental Characteristics of Blockchain:

• Decentralisation: The system operates autonomously, without a central authority; it is governed by numerous custodians.
• Immutability: Once data is recorded on the blockchain, altering it without affecting all subsequent blocks becomes unfeasible.
• Transparency: Any changes to the public blockchain are visible to all, ensuring transparency, with all transactions remaining permanent and unalterable.

Blockchain’s Essential Role in Agriculture

Blockchain technology is poised to revolutionise agricultural supply chains by bolstering transparency, efficiency, and traceability. This transformation not only reduces costs by removing intermediaries but also enhances food safety by enabling real-time monitoring of the food’s journey from farm to consumer.

Principal Advantages of Blockchain in Agriculture Include:

• Enhanced Trust: Increased transparency and data accuracy foster trust.
• Reduction in Fraud: Provides a secure, transparent log of transactions.
• Improved Compliance: Enhanced traceability aids in adhering to safety standards.

Applications of Blockchain in Agricultural Supply Chains

Traceability and Transparency

In agriculture, traceability refers to the capability to track each step of the food’s journey from its origin to the end consumer. Blockchain significantly fortifies this capability by providing a tamper-proof digital ledger. A notable implementation is by the global retail giant Walmart, which utilises blockchain to track its sales of leafy greens, enabling them to quickly trace the source of greens in real-time, thus efficiently addressing issues like contamination.

Smart Contracts for Elevated Efficiency

Smart contracts, or self-executing contracts with the terms of the agreement embedded directly into code, greatly reduce the need for manual intervention by automating transactions like payments when predefined conditions are met.

Impact on Small and Medium Enterprises (SMEs)

Blockchain proves especially beneficial for small to medium agricultural enterprises, granting them access to new markets and simpler methods to authenticate the quality and ethical sourcing of their products, a game-changing development for small-scale farmers in developing nations.

Operational Efficiency

Blockchain introduces substantial operational efficiencies by digitising supply chains, diminishing reliance on error-prone and slow paper-based records. For instance, in grain supply chains, blockchain enables real-time management, substantially reducing losses and inefficiencies.

Food Safety and Consumer Confidence

Blockchain aids food safety through robust traceability systems that swiftly pinpoint contamination sources, mitigating health risks and economic losses associated with food recalls. For consumers, blockchain bolsters confidence by providing easily accessible records of a product’s journey from farm to table.

Challenges and Considerations

Technological and Infrastructural Barriers

Despite its advantages, the integration of blockchain into existing agricultural frameworks poses significant technological challenges and incurs high costs. Many farming operations, particularly in less developed countries, lack the necessary digital infrastructure.

Strategies to Overcome Adoption Barriers

Overcoming the inherent resistance to technological change involves demonstrating the tangible benefits of blockchain and supporting stakeholders through education and training.

Future Prospects and Innovations

As blockchain technology evolves, its applications are expected to expand, potentially integrating with emerging technologies like the Internet of Things (IoT) and artificial intelligence (AI) to further enhance data analytics and automate processes.

Conclusion

Blockchain technology will transform the agricultural industry by improving traceability, efficiency, and consumer confidence. Despite the difficulties in the road ahead, the progress being made and the growing awareness are clearing the path for wider acceptance. With ongoing innovation in the agricultural industry, the future looks promising for farmers worldwide with improved food safety, decreased waste, and increased economic opportunities.
