Brown stuff that sticks to your shoes might seem an unlikely hero in the story of our fight against the climate crisis. But mud and soil are currently being tipped for starring roles as scientists seek ways to capture more carbon.
Simple techniques to improve soil quality could help us reach our climate targets, scientists say.
Crop rotation, planting cover crops and using direct drilling could store around 31 gigatonnes of carbon dioxide annually, according to land management company, Downforce Technologies.
And that would make a sizable impact since it is close to the 32 gigatonnes gap that exists between planned emissions reduction globally per year, and the amount of carbon that must be cut by 2030 to stay within 1.5C global heating, Downforce’s Chief Scientist, Jacqueline McGlade told The Guardian.
How is the World Economic Forum helping farmers with technology?
Soil as superhero
The calculations underscore the vital part soil plays. Yet 33% of soil is already degraded around the world, reports the UN. More carbon resides in soil than in the atmosphere and all plant life put together, research shows.
A recent study has found that more than half of Earth's species live in the soil, with the study finding it was the world's most biodiverse habitat.
The importance of healthy soil around the world was the focus of a panel chaired by Tania Strauss, the World Economic Forum’s Head of Food and Water, at the Forum’s 14th Annual Meeting of the New Champions (AMNC) in Tianjin, People’s Republic of China.
Science, technology and nature can come together to help restore soils, the panellists said.
Innovation to restore soil
Restoring soils that are currently degraded has the potential to store much more carbon, Sivertsen said, but innovation is vital.
The Forum’s 100 Million Farmers programme is a multi-stakeholder platform promoting action on farms to underpin the transition to net-zero food systems by 2030.
Access to technology and smart farming tools forms a large plank of the strategy for smallholder farms, Doris Yu, Senior Vice-President at Yara International, told AMNC.
Better soil has huge potential to help mitigate the climate crisis, and it’s currently untapped, said Fan Shenggen, Chair Professor, China Agricultural University, at the same event.
“Without soil, there would be no human beings,” Shenggen said. “That’s the importance of soil.”
