What if the food system could be a climate solution instead of a climate problem? That’s the question Eva Goulbourne explores with Renée Vassilos, Director of Agriculture Innovation at The Nature Conservancy (TNC), in the debut episode of Everything But the Carbon Sink. Together, they unpack the role of agriculture in addressing the climate crisis—and why capital and innovation are key to unlocking its potential.
“Agriculture has a tremendous negative footprint in terms of greenhouse gas emissions,” said Vassilos. “But it’s also uniquely positioned to be a carbon sink.”
Vassilos explained that by focusing on soil health, reduced inputs, and practices like cover cropping and rotational grazing, farms can become drivers of climate resilience, biodiversity, and profitability. “At the core of how we think about regenerative agriculture, it is about soil health. It’s about rebuilding soil health,” she said. “Because as we think about the role agriculture can play in climate change mitigation, halting and reversing biodiversity loss, and improving freshwater systems, it all anchors around rebuilding soil health.”
Goulbourne believes that the concept of regenerative agriculture can feel messy and hard to pin down. “There are practices, there are values. It’s not one-size-fits-all.” Vassilos agreed, noting that what works in one region or operation might not work in another. “Each operation will have to anchor itself in rebuilding soil health, and the tools they’ll use will vary.”
They also discussed the economic realities farmers face. “It all comes down to economics,” said Vassilos. “The operations that are shifting to regenerative are doing so because it makes business sense, often because they’re producing higher-margin food crops.”
However, with high labor costs, land leasing complexity, and limited short-term ROI, adoption remains slow. To address this, TNC is investing in early-stage agtech solutions aimed at removing the so-called green premium. One example cited by Vassilos is SwarmFarm, an Australian startup building autonomous, lightweight farm equipment. “Their robots enable precise nitrogen application without the heavy soil compaction of traditional machinery,” Vassilos explained.
My favorite part of the conversation is when Goulbourne asked Vasillos what the “ugly baby” in this space is – in other words, the problem in ag that no one wants to touch.
Vassilos didn’t hesitate: “Addressing labor challenges is just absolutely critical,” she said. “These regenerative systems are more complex. That often means they take different kinds of labor, sometimes more labor. We have to be honest about that.” She pointed to emerging technologies in automation as promising, but noted it’s still an underfunded area given its significance.
It was a great conversation, one that really highlights Eva Goulbourne’s unique perspective on the different pathways for capital to help address the climate challenge through the food system.
