Africa's savanna grasses found to store carbon below ground

A review of experiments on African savanna grasslands finds that carbon in grass leaves and stems largely returns to the atmosphere when the plants are eaten, decompose, or burn. Long-term carbon storage in these grasslands instead happens mainly underground, especially in soils, and the review found no consistent increase in that storage across the experiments examined. The findings matter for how grassland restoration is counted in carbon schemes.

Why now: The finding challenges assumptions that grassland restoration reliably increases carbon storage, which is relevant to climate policy debates.
