WEF: Is Blockchain the Key to Sustainable Food Supplies?

The global food supply chain, valued at US$9tn, is a significant contributor to carbon emissions. The World Economic Forum (WEF) has been actively exploring strategies to make this complex industry more sustainable without compromising food availability.

Among the various solutions discussed, blockchain technology stands out as a transformative tool for enhancing transparency, traceability and security within food supply chains.

Blockchain has the potential to address many of the pressing challenges faced by the global food industry.

Traditional supply chains often suffer from inefficiencies, security vulnerabilities and a lack of transparency. These shortcomings can lead to serious consequences, ranging from excessive food waste to deaths caused by contamination.

By integrating blockchain technology, the food industry can significantly improve the quality of life globally, ensuring that food is safer, more accessible and sustainably produced.

One of the most compelling benefits of blockchain in food supply chains is its ability to provide real-time tracking of products from their source to the consumer.

This capability supports sustainability efforts by ensuring compliance with environmental, social and governance (ESG) standards and helps producers receive fair compensation.

As the WEF report highlights: “To become more sustainable, firms now need to consider how they operate as part of an extensive multi-tiered supply network with multiple supply and demand links, reverse loops, multi-way interactions and exchanges with numerous actors and non-linear dynamics.”

The transparency offered by blockchain is particularly crucial in overcoming the challenges associated with Scope 3 emissions, which originate from a business's supply and value chains.

These emissions are notoriously difficult to manage, especially when suppliers are located in countries with weaker environmental regulations.

By providing a clear and immutable record of every transaction and process within the supply chain, blockchain helps companies better monitor and reduce their carbon footprint, even across multiple tiers of suppliers.

Blockchain also addresses the issue of visibility, a common problem in traditional supply chains where companies often struggle to see beyond their first-tier suppliers. This lack of visibility weakens supply chain resilience and makes it difficult to anticipate disruptions.

Blockchain’s distributed ledger system ensures that all participants in the supply chain have access to the same information, improving communication and trust. 

One report from SettleMint outlined a useful case study, Silal Fresh, a division of the agritech company Silal, which struggled with tracing its products across the supply chain.

By adopting blockchain technology, Silal Fresh was able to integrate a comprehensive traceability system into their operations. This system, which includes consumer apps and a web-based dashboard, allowed them to record every touchpoint of their products in a blockchain ledger.

The result was a significant improvement in delivery efficiency, customer satisfaction, trust and brand loyalty.

Customers could now scan a QR code on a piece of produce and see the entire journey of that food item, from farm to table.

“We’re seeing blockchain technology’s ability to improve operations and the end-user experience grow across a number of different industries and applications today — and which will only continue into the future," adds Matthew Van Niekerk, Founder & CEO of SettleMint. 

"One of the biggest areas blockchain has the potential to transform is supply chain management. From more accurate tracking through increased transparency, to promoting more security in data exchange, blockchain can make supply chains more efficient, resilient and compliant.

"SettleMint has worked with many companies to help bring more efficiency and transparency to their supply chain through blockchain initiatives. However, we wanted to learn more about how IT and digital leaders are integrating blockchain into their supply chain management processes.”

In addition to enhancing transparency, blockchain also offers significant security advantages. Traditional supply chains are vulnerable to cyber-attacks, particularly when they rely on centralised systems.

Blockchain's decentralised nature makes it more resilient to such threats, as it distributes data across a network of nodes rather than storing it in a single location. This added layer of security is crucial in protecting sensitive information and maintaining the integrity of the supply chain.

The WEF report also emphasises the importance of sustainable innovation throughout the food supply chain, from raw materials to delivery.

Blockchain supports this by facilitating the diffusion of innovative practices and technologies that can reduce emissions, improve soil management and enhance overall farming techniques.

By making data more accessible and transparent, blockchain enables all participants in the supply chain to adopt and implement these innovations more effectively.

As the WEF continues to explore strategies for a more sustainable future, blockchain stands out as a critical tool for transforming the way we produce, distribute and consume food.
