Making soil sexy again. Why food security, biodiversity & climate change depend on it

BetterSoil Founder Azadeh Farajpour joins us to outline why the future of food, climate, and biodiversity isn't found in a lab, but in the life beneath our feet.
We’re obsessed with the "next frontier." We’re pouring billions into Mars, the metaverse, and deep-sea mining, while we’re neglecting the most vital, high-tech, and biodiverse ecosystem in existence. And it's right beneath our feet!
If the Earth were an apple, the soil that feeds 10 billion people is no thicker than that peel. Yet, we’re peeling it off and throwing it away.
We sat down with Azadeh Farajpour, founder of BetterSoil and a member of the Club of Rome, to dig into why the transition to a circular bioeconomy isn't just about high-tech biorefineries. It starts with the most complex, biodiverse, and misunderstood technology in existence: dirt.
It’s time to make soil sexy again.
The Silent Crisis: A Finite Resource in Retreat
Most people think of soil as dirt: infinite and inert. The reality is far more "insane," as Azadeh puts it. A single gram of healthy soil can contain 10 billion organisms. Over 60% of all organisms on this planet live in soil.
It’s a biological masterpiece that takes nature 1,000 years to build just one centimeter of topsoil. Meanwhile, we’re destroying it 10 to 40 times faster than it can regenerate.
Every year, 100 million hectares of soil vanish. They don't just disappear; they are "operated on" by industrial agriculture with the metaphorical knives of heavy tillage, fungicides, and synthetic fertilizers. This kills the very microbial life that makes our existence possible.
The Triple Threat: Food, Climate, and Water
The health of our soil isn't a niche "agri-tech" concern. It is the foundation of three global pillars:
The Food Gap: 95% of our food comes from the soil. In Europe, potato yields have dropped 36% in the last 20 years, largely because we’ve exhausted the land through relentless monocultures that don't give the earth a second to breathe.
The Carbon Vault: Soil is the largest carbon reservoir on Earth after the oceans. When we abuse it, it leaks carbon into the atmosphere. But when we heal it? It becomes a massive sponge. Unlike oceans, which turn acidic when they absorb CO2, soil actually gets more fertile the more carbon it stores.
The Water Battery: Healthy soil can store the equivalent of 1.5 Olympic swimming pools of water per hectare. In a world of extreme floods and "eternal" droughts, healthy soil is our best insurance policy.
From Dirt to Data: The BetterSoil Mission
Azadeh's startup, BetterSoil, bridges the gap between ancient biological wisdom and space-age data.
By partnering with the European Space Agency (ESA), BetterSoil uses satellite imagery to analyze soil health from orbit. They’re looking at "bare soil days" (how long the earth is left exposed and vulnerable) and mapping clay and sand content to predict water retention.
Their Farm Assistant app acts as a digital advisor for farmers, providing data-driven "prescriptions" for crop rotations and regenerative practices like cover cropping and biochar integration. As Azadeh puts it, you can't solve a problem you haven't identified. For many agribusinesses, the "problem" of rising costs and falling yields is actually a soil health crisis in disguise.
The Bottom Line: Soil is a Billion-Dollar Market
For the investors and startups in our ecosystem, here is the provocative truth: the bioeconomy cannot survive on a dying foundation. Regenerative soil is a billion-dollar market because it is the only way to ensure a constant, high-quality supply of biomass.
Healthy soil smells like life. It’s dark, soft, and resilient. It’s time we stopped treating it like a disposable commodity and started treating it like the living infrastructure it is. If we want a future powered by biology, we have to start by falling back in love with the earth beneath our feet.
