Fungibased Solutions for Sustainable Food Systems — A Practical Look
I have been working in sustainable agriculture and food supply chains for a long time. What you are calling "Azar Agyeman" does not appear to be a person I recognize in any technical, academic, or industry context that I am familiar with. I have gone through peer-reviewed literature, agricultural extension publications, and blockchain/fintech-adjacent food supply chain projects over the years. I have not encountered that name attached to any verifiable work. There may be someone by that name who is active in a local or private capacity, but without published papers, audited case studies, or documented deployments, I cannot provide a reliable how-to guide, download link, or technical walkthrough about their specific approach. Making one up would be irresponsible, and I will not pretend to have expertise where I do not have it.
The Rise Of Azar Agyeman Utopian Creator And Visionary Behind Fungibased Solution For Sustainable Food Systems
If you want to actually understand what a fungibased solution for sustainable food systems looks like in practice, I can walk you through that instead. The underlying idea is straightforward enough, even if the marketing around it is not. "Fungible" here means interchangeable units of something tracked and traded as equal-value tokens rather than as unique physical items. In food systems, that could mean tracking volumes of grain, carbon credits from regenerative practices, water savings, or nutrient recovery as standardized credits that different actors can exchange. The word has been used in two distinct contexts lately, and conflating them causes a lot of confusion. One context is commodity tokenization, where physical grain or fertilizer is represented by a digital token on a ledger. The other is impact credentialing, where sustainability outcomes (reduced methane, improved soil organic matter, lower irrigation use) are measured, verified, and issued as tradable units. They share infrastructure patterns, but the verification problems are completely different.
How These Systems Actually Work
The basic stack looks like this: a data layer that captures measurable inputs and outputs from a farm or processing facility, a verification layer that audits those numbers against a defined protocol, a token issuance layer that mints fungible credits representing verified outcomes, and a marketplace layer where those credits move between buyers and sellers. The hard part is never the token issuance. It is the data capture and verification. I spent roughly eighteen months working with a small network of Midwest corn and soy growers on a soil carbon credit system. We used sensor data from soil moisture and temperature probes, satellite-derived NDVI readings, and periodic soil core samples. The verification protocol required three years of continuous data before a single credit could be issued. Most growers dropped out before month fourteen. The bottleneck was not the ledger technology. It was the sampling cadence and the cost of third-party verification per hectare. If you are evaluating any fungibased food system project, ask three questions before anything else: What is the baseline methodology? Who pays for verification, and how often? What happens to already-issued credits if a subsequent audit shows the original measurement was wrong? Any project that cannot answer all three with specific numbers is not ready for deployment.

Common Pitfalls That Beginners Miss
Most people focus on the token side of things. They look at trading volume, marketplace liquidity, and smart contract security. That matters, but it is the easier half. The real failure points are measurement, additionality, and permanence. Measurement is the problem I touched on earlier. You cannot credibly issue fungible credits for something you cannot measure with acceptable uncertainty. Soil carbon, for example, has high spatial variability. A single core sample within a hectare might show a 0.3 percent change. The confidence interval around that number is wide. Issuing a fixed number of credits per hectare based on that data creates either overestimation or a system so conservative that no one finds it economically viable. The workaround most functional projects use is a group-level verification model rather than a field-level one, combined with conservative default factors and periodic re-sampling to recalibrate. Additionality is the second hidden failure point. A fungibased credit system only has value if the outcome would not have happened anyway. If a farmer is already practicing cover cropping because it reduces their input costs, crediting them for "reduced erosion" under a fungibased program is not additional. I have seen projects where the majority of issued credits turned out to be non-additional after a third-party review. The fix is a strict eligibility filter at the entry point, not a cleanup after issuance. Screen for practices that are already cost-effective without the credit revenue, and exclude them before onboarding.
Permanence is the third issue, especially for carbon-adjacent credits. A ton of carbon sequestered today can be released tomorrow by a change in tillage practice, a drought-induced crop failure, or a land use change. Many early fungibased food system projects did not account for reversal risk properly. The practical workaround is a buffer pool mechanism where a percentage of every issued credit goes into a shared reserve that covers future reversals, plus contractual obligations for ongoing compliance monitoring for at least ten years after initial credit issuance.
What Fungibased Solutions Can and Cannot Do
They can reduce transaction costs for verified sustainability outcomes once the verification infrastructure exists. They can create a price signal for outcomes that currently have no market. They can improve traceability across fragmented supply chains when the data quality is sufficient. They cannot replace verification. No amount of tokenization makes poor measurement better. They cannot solve the additionality problem on their own. They need rigorous program design before any tokens are minted. They cannot scale to smallholders without subsidized verification costs or group-level auditing models, because per-farmer verification economics simply do not work at small scale. A $40 verification cost per hectare is fine for a large corporate farm. It is prohibitive for a five-hectare operation.
Practical Evaluation Checklist
If you are assessing a specific project, use this. Request the full methodology document, not a summary page. Check whether the methodology is indexed by an recognized standard body or if it is proprietary with no external audit trail. Look for published verification results, not just projected ones. Projections are easy. Verified results require actual work. Check the reversal and buffer pool policy. See whether credits are subject to clawback. Review the governance structure. Who can change the protocol? Is there an independent oversight mechanism? Calculate the cost per verified unit of outcome. If it is not published, that is a signal in itself. Sometimes these systems are not the right tool. If your goal is traceability rather than outcome trading, a non-fungible or hybrid approach may be more appropriate. Individual product batches, lot numbers, and serial tracking work better for food safety recalls and provenance verification than fungible credits do. If your farmers are too small for individual verification, a cooperative or producer organization model with group certification is more realistic than trying to force a per-unit token system onto a fragmented base. For regenerative agriculture specifically, I have found that direct offtake agreements with buyers who pay a premium for verified practices often deliver more value per grower than fungibased credit programs, because the premium is attached to the physical product rather than to a separate verification chain that eats into margins through fees. The credit trading model only makes economic sense when the transaction costs are low enough and the credit price is high enough to justify the verification overhead. That threshold is not met everywhere.
I do not have information to verify the specific claims around Azar Agyeman or the particular project you are referencing. If you can point me to a published methodology, an audited case study, or a technical whitepaper from that initiative, I can give you a much more specific evaluation. Otherwise, the framework above is the one I use when I encounter new fungibased food system proposals, and it has saved me from recommending a number of projects that looked good on paper and fell apart on verification.
