About This Episode

The global food system faces an arithmetic problem. By 2050, Earth's population will grow to 9-11 billion while agricultural land shrinks. Simultaneously, we must increase crop yields by 60 percent to bridge the gap between projected demand and available growing space. Denmark, one of the world's most intensively farmed nations, is both a case study in the pressure and a laboratory for solutions. In this episode, Mikkel Svold speaks with Lars Horsholt Jensen, Chief Operating Officer of Food & Bio Cluster Denmark, about the mechanisms driving food scarcity and the interconnected innovations that might unlock them.

The conversation reveals a system of hidden inefficiencies. Denmark dedicates 60 percent of its land to agriculture, yet 80 percent of its crops become animal feed rather than human food. Drained peatlands, a legacy of 20th-century agricultural development, produce roughly one-third of Danish agriculture's greenhouse gas emissions. And globally, approximately one-third of all food produced never reaches human consumption. These are not separate problems. They are symptoms of a food system designed in an earlier era, now creaking under new constraints.

The episode maps emerging solutions that operate at different scales. Regenerative agriculture rebuilds soil carbon. Biochar captures carbon in mineral form. Grass and other alternative proteins offer dramatically higher yields per field than conventional crops. Strip cropping with autonomous robots allows polyculture in industrial contexts. Technology that measures spoilage at the molecular level instead of relying on dates could eliminate entire categories of waste. None of these ideas is new in isolation. The work now is in combining them and understanding how they fit together.

Key Quotes

"80% of the crops that we produce are feed for animals. So really, what we're doing in the farmland is producing something that feeds the animals, that then in turn is going to feed us."

"It's not just a linear innovation that we're talking about. It's also completely new ways of working, completely new ways of producing food and feed for the nourishment of people and animals."

"You get approximately, in comparison to a feed field of wheat, you get about two and a half times as much protein from a field of grass."

"It took wind 20 years, maybe 25, 30 years to become a profitable business on its own. You need to have the same perspective, only the fact that we have to do it in 10 years or 15 years."

About Lars Horsholt Jensen

Lars Horsholt Jensen serves as Chief Operating Officer of Food & Bio Cluster Denmark, an innovation network of 384 member organisations working at the intersection of food systems and biotechnology. In his role, he oversees projects connecting startups, established companies, and research institutions to accelerate innovation in food production, sustainability, and bio-resource management. He describes his work as having a broad overview of ideas being processed across the cluster, from regenerative farming practices to autonomous agricultural robotics.

We Perfected the Wrong System

Danish agriculture produces food with astonishing efficiency — for the wrong target. We have spent a century optimising animal feed production. The next revolution requires recognising when the metric has drifted from the purpose.
