On-the-Ground Realities of Soil Carbon MRV: Lessons from Global Project Developers

Across global agricultural landscapes, soil carbon projects are accelerating. But ensuring they deliver real, measurable climate impact requires more than sound methodology. It requires navigating the complex realities of monitoring, reporting and verification (MRV) where the work happens: on the farm.

During ISCIA's recent webinar, project developers from France, India, South Africa, and Australia shared their firsthand experience with the operational challenges involved in collecting data, supporting farmers, and scaling soil carbon projects with integrity. Their insights reveal a universal truth: high-quality MRV depends on strong relationships, reliable data, and grounded technical capacity.

Data Collection: The First and Largest Hurdle

Every panelist emphasized the same starting point: data collection is a persistent challenge in soil carbon MRV. High-integrity credits require accurate records of management practices, soil samples, and on-farm audits. But gathering that information is far from simple.

Developers must rely on self-reported data, which depends on farmers' time, availability, and comfort with digital tools. That data must be cross-checked with remote sensing or other technologies, but even the best models cannot replace boots on the ground.

In smallholder contexts, the challenge intensifies: field sizes may be as small as one acre, boundary mapping becomes time-consuming, the administrative burden on farmers grows, and costs increase significantly at scale. Even in regions with larger operations, travel across rural landscapes and recruiting technical expertise remain ongoing obstacles.

Trust and Agronomic Support Are Essential

Panelists agreed that farmer trust is the backbone of credible MRV. Maintaining that trust throughout a multi-year crediting period requires clear communication about why data is needed and how the project benefits farmers.

Several speakers emphasized the importance of agronomic support as a trust-building mechanism. While methodologies don't require it, agronomic guidance helps farmers adopt climate-smart practices, improves project permanence, and creates tangible value beyond carbon payments.

“There's no credible transition without agronomic support. That's what sustains long-term participation.”

Business Models Must Align Developer and Farmer Success

Another theme emerged across regions: the business model must support the farmer, not just the carbon outcome. Developers shared examples of structuring contracts with performance breaks, building long-term value pathways, and giving farmers multiple levels of engagement — especially in community-based landscapes.

Across all systems, successful developers recognise carbon as an agricultural product that can open new revenue streams. Helping farmers see that value is critical for participation and permanence.

Innovation Is Accelerating, but Ground Truth Remains Critical

Methodologies are evolving quickly, driven in part by industry collaborations. Yet panelists stressed that innovation must always be grounded in reality. Technology can help streamline parts of MRV, but accurate, credible soil carbon measurement still requires real-world data, technical expertise, and farmer partnership.

While soil carbon markets are advancing rapidly, delivering high-integrity MRV remains a complex operational effort. The fundamentals — trust, data, agronomy, and aligned incentives — are universal across geographies.
