Fighting food waste

Dec 19, 2023

Dr. Digvir Jayas is on a mission to stop grain spoilage. The researcher has been helping farmers and grain managers reduce spoilage losses for 40 years. He recently published a new study that used the Canadian Light Source at the University Saskatchewan to peer inside grains themselves, looking for the signs of spoilage and resistance.

Spoiled grain represents a huge pool of potential food that could help feed a growing global population. Spoilage rates vary greatly between grains and storage conditions, from as low as 1% of stored grain lost up to 50%.

“So, if you took an average of 20% loss, that would mean 640 million tonnes of grain is being lost globally on an annual basis,” says Jayas, who conducted the research while he was in the Department of Biosystems Engineering (Price Faculty of Engineering) at the University of Manitoba. “We could feed 1.5 billion people by preventing that loss through spoilage.”

To understand how the grain itself can be bred, and specific varieties selected to maximize storage potential, his team focused on hard durum wheat, which spoils less easily than soft wheats.

“The CLS has such a unique capability to look at the composition of materials at a nano or micro level. When grain spoils, there are unique changes occurring in the grain, and we were able to look at those changes.”

Video: From Conventional to Regenerative: Will Groeneveld’s Journey Back to the Land

"You realize you've got a pretty finite number of years to do this. If you ever want to try something new, you better do it."

That mindset helped Will Groeneveld take a bold turn on his Alberta grain farm. A lifelong farmer, Will had never heard of regenerative agriculture until 2018, when he attended a seminar by Kevin Elmy that shifted his worldview. What began as curiosity quickly turned into a deep exploration of how biology—not just chemistry—shapes the health of our soils, crops and ecosystems.

In this video, Will candidly reflects on his family’s farming history, how the operation evolved from a traditional mixed farm to grain-only, and how the desire to improve the land pushed him to invite livestock back into the rotation—without owning a single cow.

Today, through creative partnerships and a commitment to the five principles of regenerative agriculture, Will is reintroducing diversity, building soil health and extending living roots in the ground for as much of the year as possible. Whether it’s through intercropping, zero tillage (which he’s practiced since the 1980s) or managing forage for visiting cattle, Will’s approach is a testament to continuous learning and a willingness to challenge old norms.

Will is a participant in the Regenerative Agriculture Lab (RAL), a social innovation process bringing together producers, researchers, retailers and others to co-create a resilient regenerative agriculture system in Alberta. His story highlights both the potential and humility required to farm with nature, not against it.
