Livestock grazing may boost soil carbon storage in Iceland's subarctic grasslands‎

Grassland plants transfer large amounts of carbon to soil through their roots, and most of that carbon is stored underground. Therefore, promoting soil carbon storage can help combat climate change. Grazers feed on grassland plants, and conventional wisdom often assumes that removing grazers benefits carbon storage, but a new study in Global Change Biology Communications reveals that the opposite may be the case.

After four years of research, the European collaborative project Blue Transition, led by the LIAG Institute for Applied Geophysics in Hanover, takes stock. The final report brings together the findings from 16 pilot regions in six countries and identifies three key levers to strengthen climate resilience: changing land use, improving soil health and diversifying water resources and optimizing their use.
